In the ecological conditions on the farm Ezăreni-Iaşi was organized research regarding the effect of some biodegradable<br />
biostymulators at concentrations of 50 ppm, 25 ppm and 12.5 ppm in the period 2008-2011. The treatments were<br />
performed with biostymulators BCO-4 K (potassium salt of the acid-amido-4-chloro-phenoxyacetic sulfonyl), with and<br />
without zinc acetate and BCO - 4 DMA (dimethylamine salt of the acid chloride 4 2 amidosulfonil - phenoxyacetic) to<br />
varieties Boema, Crina and Flamura 85 (in 2010 to 2011 variety Arieşan). The research was conducted on a cambic<br />
chernozem soil, climatic conditions are favorable wheat, especially in 2010-2011. Research results revealed that on<br />
average three years, the highest yield of 7569 kg/ha was recorded in biostymulators BCO - 4 K + zinc acetate, with a<br />
production increase of 23.47% from control variant (water treatment) and 7.57% compared to the control variant 2<br />
(BCO - 4 DMA). Averaged over three years, the concentration of 50 ppm achieved the highest yield of 7506 kg/ha and<br />
to Boema variety 7568 kg/ha. The best interaction between factors was found BCO - 4 K + acetate Zn x 25 ppm x<br />
Boema with 7942 kg/ha, averaged over three years, with 14.85% higher than in control variant (BCO - 4 DMA x 12 , 5<br />
ppm x Flamura 85). Use of biostymulators for winter wheat is a sustainable action.<br />
Key words: biostymulators, concentrations, wheat<br />
Increasing safety and food security of the<br />
population is a concern for both producers and<br />
processors of raw vegetables (Gherghen et al.<br />
1988; Goian 1986).<br />
By using new biodegradable and nontoxic<br />
stimulators worldwide and in Romania, along<br />
starter fertilizer with preparate containing primary<br />
nutrients (N,P,K), secondary (Ca, Mg, S) and<br />
micronutrients (B, Cu, Fe, Mn, Zn), to obtain<br />
significant production increases, quantitative and<br />
qualitative (Goian, 1986; Kleijer et al., 2011; Favre<br />
et al. 2006; Oniscu and Trofin 2002).<br />
Wheat cultivars, their genetic qualities, more<br />
productive, to be and baking quality, protein<br />
content, wet gluten and starch as influenced by<br />
treatments applied (Kleijer 2002; Fossati, 1990;<br />
John Ionela 1990).<br />
Conception and development of new<br />
chemical structures of class sulphonamides used as<br />
regulators of growth substances innovative is a<br />
continual research, to use in different cultures,<br />
including the wheat (Oniscu 2002).<br />

MATERIALS AND METHODS<br />
In the period 2008-2011 on the farm Ezăreni -<br />
Iaşi take place at research on the effect of<br />
biostymulators, recently obtained in different<br />
concentrations on the biology and production of three<br />
Romanian winter wheat varieties.<br />
The biostymulators used were obtained from<br />
the Technical University "Gh. Asachi" of Iasi, the<br />
sulfonamides of phenoxyacetic derivatives and their<br />
salts, being biodegradable, acting through the<br />
application extraroot in different concentrations of 50<br />
ppm, 25 ppm and 12.5 ppm.<br />
Extraroot application of plant growth<br />
advantage is to avoid their immobilization in the soil,<br />
the possibility of applying different biofaze of plants,<br />
using small quantities and with herbicides or<br />
pathogens control products. Sulfonamide is today a<br />
major class of chemicals, with effect or growth<br />
regulator herbicides, lack of toxicity to humans,<br />
animals, bees, fish, whilst being biodegradable.<br />
For treatment with biostymulators were used:<br />
potassium salt of the acid-4-chloro-phenoxyacetic<br />
amidosulfonil (BCO-4K), without and with zinc acetate<br />
and dimethylamine salt of the acid chloride 4phenoxyacetic<br />
2 amidosulfonil (BCO-4DMA)<br />
cosncentrations of 12.5 ppm, 25 ppm and 50 ppm.

Has been made three varieties of wheat expreriente:<br />
Boema, Crina and Flamura-85.<br />
In 2010-2011 Flamura-85 variety was replaced<br />
with Arieşan variety. Boema variety within the group<br />
to early varieties with high productivity. Crina variety<br />
is a variety of early, high yielding, resistant to winter<br />
and variety Flamura 85 is a early variety, with good<br />
milling and baking characteristics. All three varieties<br />
have been created to ICCPT Fundulea. Arieşan<br />
variety was obtained from SCDA Turda, is winter<br />
resistant, productive and suitable for Moldova and<br />
Transilvania. Climatic conditions during the<br />
experiment were favorable for winter wheat, standing<br />
out in terms of favorability for wheat crop year 2010-<br />
2011.The soil that was experienced was a cambic<br />
chernozem, with a pH of 7.05, 30.03% humus,<br />
0.156% total nitrogen, 69 ppm P and 366 ppm K.<br />

Calculation of results was done by variance<br />
analysis method.<br />
RESULTS AND DISCUSSION<br />
Analyzing wheat production obtained, from<br />
table 1, that the agricultural year 2008-2009 were<br />
recorded production of 6045 kg/ha to control<br />
variant, treated with water and 7458 kg/ha treated<br />
variant with biostymulator BCO-4K + acetate zinc;<br />
production in 2009-2010 ranged from 5868 kg/ha<br />
in the variant treated with water and 7147 kg/ha in<br />
variant BCO-4 K+Zn acetate, in 2010-2011,<br />
production was 6479 kg/ha in control variant of<br />
water and 8102 kg/ha in variant BCO-4 K + zinc<br />
acetate.<br />

The semi-natural grasslands in Apuseni Mountains are particularly important for the sustainable development of this<br />
region. The future development strategies must take into consideration the conservation of grassland plant diversity. In<br />
Apuseni Mountains there are numerous caves and a traditional landscape, these forming the area’s wealth. Their joining<br />
with agro-tourism and performing a sustainable agriculture would significantly level up the wellbeing of the local<br />
population, who are in need of new income sources considering that the wood resources are more and more reduced. In<br />
Gârda de Sus there are considerable areas of semi-natural grasslands which lately have been traditionally used.<br />
Nowadays, some of them have been abandoned and others irrationally intensified. Therefore, the objective of this paper<br />
was to evaluate the effects of organic fertilization upon the sward in order to recommend certain versions which have<br />
minor repercussions upon the plant diversity. The research was carried out in Apuseni Mountains, in an experimental<br />
field with one experiences with organic fertilizers (T1 control, T2 10 t ha -1 manure, T3 20 t ha -1 manure, T 4 30 t ha -1<br />
manure). Giving organic fertilizers caused installation of Festuca rubra L. and Trisetum flavescens L. at the treatment<br />
using 10 t ha -1 manure and Trisetum flavescens L. at using 20 and 30 t ha -1 manure. The treatment with 10 t ha -1 manure<br />
induced a growth of the plant diversity and by raising the manure quantity did not cause important changes with respect<br />
to the species’ number. For future management actions that are meant to maintain the plant diversity in Apuseni<br />
Mountains, the organic fertilization with 10 t ha -1 manure quantities annually administrated or once in two years is<br />
recommended.<br />
Key words: mountainous grassland, organic fertilization, plant diversity, frequency of the species, abundance of the<br />
species<br />
Mountain grasslands include some of the<br />
most important high nature value areas in Europe,<br />
and high-biodiversity mountain farmland can<br />
increase tourism incomes and is a potential seed<br />
source for local biodiversity restoration (Hopkins,<br />
2011). The grassland system can provide<br />
ecosystem services such as soil conservation, water<br />
quality protection, biodiversity conservation,<br />
medicinal plants, pleasing landscapes, soil carbon<br />
storage and greenhouse gas mitigation (Sanderson<br />
and Wätzold, 2010). Grassland biodiversity is an<br />
important consideration in many agrienvironmental<br />
policies (Orth et al. 2010). The<br />
grasslands in Europe suffer a dramatic loss of<br />
biodiversity features because of fertilization, land<br />
abandonment or the transformation of grassland<br />
into cropland (European Environment Agency,<br />
2007). The first systematic assessment of Europe’s<br />
most vulnerable habitat types and species has<br />
already shown that grasslands in particular have an<br />
unfavourable conservation status (Bruchmann and<br />
Hobohn, 2010). In less-favoured areas, this can<br />

take form of preserving plant diversity, e.g.<br />
through low-input farming system (Duru et al,<br />
2010). Semi- natural grasslands need a<br />
management system which supports biodiversity<br />
conservation (Rotar et al., 2010). Being one of the<br />
most diverse plant communities, mountain<br />
meadows are the habitat for many rare species<br />
(Zarzycki and Misztal, 2010). Manure fertilization<br />
contributes to grasslands phyto-diversity, while<br />
spring overgrazing or frequent mowing are<br />
disadvantageous (Nettier et al., 2010). Questions<br />
remain as to what level of organic fertilization<br />
optimally maintains the plant diversity of<br />
meadows. Organic fertilization and rational use of<br />
fertilizers can produce substantial increases of the<br />
production and biodiversity and fodder quality<br />
improvement (Vîntu et al., 2008). In the central<br />
part of Apuseni Mountains, fertilization by manure<br />
is the most important component of the traditional<br />
management that means to increase the biomass<br />
yield, species diversity and identity of the cultural<br />
landscape. Nowadays, in Romania, on the
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
grasslands of Apuseni Mountains, a management<br />
that involves manual labour, with horses-drawn<br />
carts and great consumption of time still is<br />
performed. This type of management has created<br />
over time great plant diversity (Auch, 2006). The<br />
meadows present within the perimeter of the Gârda<br />
de Sus commune, Apuseni Mountains, Romania,<br />
are highly plant diversified, due to traditional<br />
management performed over long periods of time.<br />
Most of the traditional management techniques use<br />
organic fertilization via manure combined with the<br />
mixed uses (Gârda, 2010). The recent changes<br />
(access roads improvement, better livelihood etc.)<br />
will influence the grasslands maintenance manner.<br />
Our paper’s objective was to evaluate the effects of<br />
organic fertilization upon the sward in order to<br />
recommend certain versions which have minor<br />
repercussions upon the plant diversity.<br />
MATERIALS AND METHODS<br />
The experimental field is located in the<br />
Ghetari, Gârda de Sus village, Alba County, Apuseni<br />
Mountains, at 1130 m elevation and it was founded in<br />
2001, using the random blocks method. The<br />
experiment fields included 4 treatments in 4<br />
1<br />
manure, T3 20 t ha -1<br />
replications (T 1 control, T 2 10 t ha -<br />
manure, T 4 30 t ha -1 manure). Each plot measures 10<br />
m 2 . The technological inputs administration took place<br />
annually in early spring. The organic fertilizer came<br />
from cattle and horses having the following elements<br />
content: 0.40 N, 0.39 P and 0.45 K. The experimental<br />
field was placed on Terra Rossa soil having the<br />
following features: soil pH 5.34, N total 0.212 %, P<br />
mobile 3 ppm, K 25 ppm. Thus, a medium supply in N<br />
and extremely low in P and K are noticed. The floristic<br />
studies were performed according to Braun-Blanquét<br />
method. For floristic data we have used PC-ORD<br />
program which performs multivariate analysis of<br />
ecological data entered in spreadsheets 19 . Our<br />
emphasis is on nonparametric tools, graphical<br />
representation, randomization tests and bootstrapped<br />
confidence intervals for analysis of community data.<br />
We also used the MRPP (Multi Response<br />
Permutation Procedures), which is a nonparametric<br />
procedure for testing the hypothesis of no differences<br />
between two or several groups of entities. The<br />
method implies the statistic T-test which describes<br />
the separation among the groups, meaning the more<br />
negative is T, the stronger is the separation. The<br />
agreement statistic A describes within - group<br />
homogeneity, compared to the random expectation.<br />
Also, Non-metric Multidimensional Scaling (NMS)<br />
was used, which is an ordination method well suited<br />
to data described as not normal or arbitrary,<br />
discontinuous, or otherwise questionable scales.<br />
NMS is generally the best ordination method for<br />
community data. NMDS does not alter the ordination<br />
too much and is replacing the correlation coefficient<br />
by the frequently used Bray-Curtis index which<br />
changes the result considerably 20. A Monte Carlo<br />
test of significance was included. The orderabundance<br />
and order- frequency correlations give us<br />
14<br />
a synthetic view and are extremely useful in<br />
comparative studies 21.<br />
RESULTS AND DISCUSSION<br />
Administrating organic fertilizers produced<br />
a vegetation ordination in 4 floristic groups<br />
specific to each treatment (figure 1). Control<br />

In the context of global climate change and the different scenarios developed in this direction, quantifying soil<br />
respiration becomes an issue of major interest for both researchers and farmers. The objective of this study is to asses<br />
the use of city sludge as fertilizer in agriculture, with special reference to soil respiration with alfalfa grown on in terms<br />
of ensuring environmental protection and the integrity of human health. Number of soil microorganisms and their<br />
composition is an important practical point in assessing biological activity. The effect of fertilization with city sludge<br />
upon soil respiration on alfalfa culture was studied in an experiment with 8 variants where were applied different doses<br />
of city sludge and manure.Soil respiration is closely related to microbiological activity in soil. Determination of soil<br />
respiration allows obtaining and processing for a large number of data which will provide greater accuracy in<br />
estimating soil CO2 flux. Results show that the activity of soil microorganisms is much stronger in July than in October.<br />
In July, the biggest differences from the control, in terms of soil respiration were recorded in variants fertilized with 40,<br />
60 t / ha city sludge and 20 t / ha manure, which is 0.69; 0.52 and 0.24 are noted in statistically highly significant. The<br />
best results in terms of soil respiration were recorded in October of 2011 in the variant treated with 40 t / ha city sludge<br />
with a value of g/m 2 /h 2.78 and with a 0.66 g/m 2 / h difference to the version control.<br />
Keywords: city sludge, soil resoiration, alfalfa, environmental protection.<br />
Soil respiration is defined as the<br />
consumption of molecular oxygen and producing<br />
carbon dioxide in the soil (Hillel D., 1998),<br />
resulting in carbon dioxide emissions from the soil<br />
into the atmosphere in significant quantities for the<br />
global carbon balance (Buyanowski G., 1983).<br />
There are two components of soil respiration<br />
namely: autotrophic respiration or breathing live<br />
plants (mainly by roots) and heterotrophic<br />
respiration microbiological is a biological<br />
respiration and bacterial decomposition of plant<br />
residues (Trumbore S., 2002).<br />
In the presence of molecular oxygen as<br />
oxidants in the soil pores, the respiration is taking<br />
place is aerobic, but as oxygen is consumed, it may<br />
be insufficient, especially with lower capacity<br />
micropore aeration, leading to anaerobic<br />
respiratory processes in that acceptorul final<br />
electron is not oxygen, but other oxidizing agents<br />
(nitrates, nitrites, carbon dioxide) - but they all<br />
produce energy produced lower than for aerobic<br />
respiration. Some constituents of the soil processes<br />
involved in plant development may become<br />
unavailable due to anaerobic respiration, which<br />
alter their composition (Zarrnea G., 1994). For<br />
example, nitrates can be reduced to nitrites, toxic<br />
1 University of Agricultural Sciences and Veterinary Medicine, Cluj-Napoca<br />
to plants or molecular nitrogen, which is hardly<br />
usable for their growth (Leonard I., 2007).<br />
Anaerobic soil conditions encountered in cases of<br />
prolonged water saturation, compaction and<br />
subsidence, are unfavorable for normal<br />
development of crops and soil aeration by specific<br />
work is recommended in these situations.<br />
MATERIALS AND METHODS<br />
The experience has been carried out during<br />
two experimental years, 2010-2011, and has been<br />
placed on the bill faeozom from Bolduţ, Cluj County,<br />
owned by ARDS Turda.<br />
The soil is slightly alkaline with a pH of 8.07<br />
within the Ao horizon and a 8.39 pH within Bt horizon,<br />
with a rate of 0.24% N, 41 ppm P and 342 ppm K.<br />
The experiences have been placed using the<br />
latin rectangle method in 4 repetitions with 8 variants:<br />
V1-control, V2 - 20 t / ha sludge, V3 - 30 t / ha sludge,<br />
V4 - 40 t / ha sludge, V5 - 60 t / ha sludge, V6 - 20 t /<br />
ha manure, V7 - 40 t / ha manure and V8 - 60 t / ha<br />
manure.The sludge that has been used was provided<br />
by the wastewater from Cluj-Napoca. The sludge has<br />
been first fermented in methantanks and dried on<br />
platforms for 8 months, having the following<br />
characteristics: 3.56% N, 2330 ppm P, 816 ppm K<br />
and 7.06 neutral pH. The chemical analysis of the
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
sludge and the soil profile characterization were<br />
provided by OSPA Cluj-Napoca.<br />
The biological material that has been used was<br />
alfalfa, Madalina variety. In our experiment from<br />
Bolduţ, for monitoring soil respiration we used a<br />
closed dynamic system (U.S. company PP System).<br />
The principle method involves isolating a volume of<br />
atmosphere from soil for some time, capture CO 2 and<br />
then determine its alkaline solutions (Sandor M.,<br />
2010).<br />
RESULTS AND DISCUSSION<br />
Measurement of soil respiration and soil<br />
evapotranspiration from our experiment were<br />
performed using closed dynamic system CIRAS 2<br />
July 2011 and October that same year. In July of<br />
2011 there were differences between version<br />
control and variants application of city sludge and<br />
manure.<br />
The biggest differences in terms of soil<br />
respiration were recorded in variants fertilized with<br />
40, 60 t / ha city sludge and 20 t / ha manure,<br />
which were noted in very significant statistically<br />
(table 1).<br />
The highest values in terms of soil<br />
respiration occurred in the variant treated with 60 t<br />
/ ha sludge, where he obtained a value of 3.85<br />
g/m 2 /h (with a difference of 0.69 g / m 2 / h to the<br />
version control), followed by the variant treated<br />
with 40 t / ha city sludge with a value of 3.68<br />
22<br />
g/m 2 /h (with a difference of 0.52 to version control<br />
g/m 2 /h ). In contrast stands the variant treated with<br />
20 t / ha city sludge with a value of 3.26 g/m 2 /h<br />
soil respiration (with a difference of 0.07 g/m 2 /h to<br />
version control).<br />
A second measurement of soil respiration<br />
was performed in October of 2011, and since<br />
statistically, in all experimental variants have been<br />
very significant increases from unfertilized control<br />
variant. The highest values of soil respiration in<br />
October of 2011 were recorded in the variant<br />
treated with 40 t / ha city sludge, with a value of<br />
2.78 g/m 2 /h (with a g/m 2 /h 0.66 difference from<br />
control variant) and the variant treated with 60 t /<br />
ha manure, with a value of 2.75 g/m 2 /h (with a<br />
difference of 0.63 g / m 2 / h to the version control).<br />
The lowest value was observed in the variant<br />
treated with 60 t / ha city sludge g/m 2 /h of 2.43<br />
(with a difference of 0.31 g/m 2 /h from version<br />
control) (table 2).<br />
Comparing the two periods analyzed, soil<br />
respiration values in July (range from 3.16 to 3.85<br />
g/m 2 /h) are much higher than in October (values<br />
between 2.12 to 2.78 g / m 2 / h) (figure 1). This<br />
shows that temperature is one of the factors<br />
influencing soil respiration as very high, so the<br />
activity of microorganisms during the warm season<br />
is more intense than in the coldest of the year.<br />

Soil respiration is the main link in the<br />
carbon cycle in which CO2 is fixed by<br />
terrestrial plants back into the atmosphere,<br />
being defined as the consumption of molecular<br />
oxygen and production of CO2 in the soil. Soil<br />
respiration is closely related to microbiological<br />
activity in soil (protozoa, algae, fungi,<br />
actinomycetes, bacteria) (Vidican R., 2007).<br />
In July, the biggest differences from the<br />
control, in terms of soil respiration were<br />
recorded in variants fertilized with 40, 60 t / ha<br />
city sludge and 20 t / ha manure, which is<br />
0.69; 0.52 and 0.24 are noted in statistically<br />
highly significant.<br />
The best results in terms of soil<br />
respiration in October of 2011 were recorded<br />
in the variant treated with 40 t / ha city sludge<br />
with a value of g/m 2 /h 2.78 and with a 0.66<br />
g/m2/ h difference to the version control.<br />

An experience in farm Ezăreni-Iasi organized in 2008-2011, on cambic chernozem soil, we studied the effect of<br />
biostymulators concentration (BCO - 4 DMA, BCO - 2 K; BCO - 2 K + acetate Zn) in three concentrations applied (50<br />
ppm, 25 ppm, 12.5 ppm) in three biophases (twinning, bellows, flowering) for winter wheat, variety Boema. Climatic<br />
conditions were favorable for winter wheat in terms of temperature and rainfall, crop year 2010-2011 the most<br />
favorable for wheat. Averaged over three years, comparing yields with version control treated with water, the highest<br />
yield was achieved with biostymulators BCO-2 K + zinc acetate, with 6322 kg / ha, 26.16% difference is very<br />
significant. Comparing yields with BCO - 4 DMA (control variant 2) production increase was 11.14%, distinct<br />
significantly in the variant BCO - 2 K + zinc acetate. In the three years average the concentrations of 12.5 ppm and 25<br />
ppm were found higher comparated with the concentrations of 50 ppm. Between biophases application of growth<br />
regulators no registered statistically differences, which requires obtaining of similar production value. The interaction<br />
between factors showed that the best variant BCO - 2 K x 25 ppm x flowering, with an average of 6844 kg / ha, 11.77%<br />
higher than the production control variant (BCO - 4 DMA x 12.5 ppm x twinning). The biostymulators used were<br />
potassium salt of the acid-4-chloro-phenoxyacetic amidosulfonil (BCO - 4 K), without and with zinc acetate and<br />
dimethylamine salt of 4-chloro acid, 2-phenoxyacetic sulfonyl amide (BCO - 4 DMA) obtained of the Proff. C. Oniscu<br />
from the Technical University "Gh. Asachi" of Iasi.<br />
Key words: biostymulators concentration, biophase, winter wheat<br />
Increasing agricultural production, both<br />
quantitatively and qualitatively, is a key concern<br />
worldwide and in Romania, to ensure food safety<br />
and security of the population.<br />
In the context of increasing the number over<br />
7 billion people of Earth in 2011 and growing<br />
demand for raw materials for the industrialization<br />
of farming, agricultural development is a primary<br />
goal.<br />
To increase the quantity and quality of<br />
wheat production, the main cereal bakeries are<br />
followed:<br />
- technological measures on mechanization<br />
of process improvement, utilization of fertilizers<br />
and pesticides, ecosystems protection;<br />
- use of new techniques in wheat crop, such<br />
as fertilization extraroot and use biostymulators;<br />
- general, economic and social measures,<br />
such as rational use of land, provision of material<br />
resources, technical and financial cooperation at<br />
national and European level in this area (Bîlteanu<br />
Gh, 2003; Borlan Z., 1989).<br />

All these have direct impact on quality of<br />
life in sufficient quantities and quality of food that<br />
can be obtained by using biodegradable<br />
stimulators, increasingly require sustainable<br />
agriculture (Gherghen I., et al., 1988; Goian M.<br />
1986; Merlo L., Nuzzo, V., 1987; Neamtu G., F.<br />
Irimie, 1991).<br />
Biostymulators application extraroot wheat<br />
has the following advantages (GOIAN M., 1986;<br />
Borina, AK, 1959; Oniscu C., 1993):<br />
- prevents their immobilization in the soil;<br />
- can be applied in different biophases of<br />
wheat;<br />
- use small amounts of biostymulators;<br />
- is applied in conjunction with other<br />
substances, for weed control or pest and disease<br />
control;<br />
- apply modern means (airplane, helicopters<br />
etc.).

MATERIALS AND METHODS<br />
The research was conducted on a cambic<br />
chernozem in the Ezăreni farm in 2008-2010.<br />
The soil that had experienced a pH of 7.49 per<br />
depth 0-15 cm, humus 3.42%, 0.188% total nitrogen,<br />
101 mg and 594 mg KAL PAL to 100 g soil. In the<br />
crop year 2008-2009 temperatures recorded<br />
exceeded the annual average of 2 o C and rainfall was<br />
162 mm lower. The agricultural year 2009-2010, the<br />
period october 2009 - july 2010 exceeded the annual<br />
average temperature recorded with 0.76 o C and<br />
rainfall exceeded the annual average of 68.6 mm,<br />
since wheat is more favorable than before. In 2010-<br />
2011 rainfall was 40.4 mm lower than the annual<br />
average, but were distributed more evenly on critical<br />
biofazele asle wheat, recorded the highest production<br />
cariopse in all variants investigated.<br />
Experience has been placed in subdivided<br />
parcels, with four repetitions, with the following<br />
factors:<br />
Factor A - Biostymulators with three<br />
graduations:<br />
- a 1 - BCO-4DMA biostymulators<br />
- a 2 - BCO-2 K biostymulators<br />
- a 3 - BCO-2 K + zinc acetate biostymulators<br />
Factor B - concentration of promoters with<br />
three graduations:<br />
- b 1 - concentration of 50 ppm<br />
- b 2 - concentration of 25 ppm<br />
- b 3 - concentration of 12.5 ppm<br />
Factor C–Biophases biostymulators application<br />
with three graduations:<br />
- c 1 - twinning biophases<br />
- c 2 - "bellows" biophases<br />
- c 3 - flowering biophases<br />
The variety used was Boema - because it was<br />
the best behavior in other previous experience, with<br />
82 ± 0.8 cm height, 41 ± 2.6 g TSM, 77 ± 2 kg HM<br />
and productivity over 6 to/ha.<br />
A surface plot was 16 m 2 .<br />
The seeds were treated against pests and<br />
pathogens using a density of 600 g.s./m 2 at sowing.<br />
Common technology was used in experimental<br />
26<br />
conditions. During the vegetation phenological<br />
observations were made and biometric<br />
measurements. Statistical calculation was made by<br />
variance analysis method.<br />
RESULTS AND DISCUSSION<br />
Following research in three years (2008-<br />
2009, 2009-2010 and 2010-2011) was resulted<br />
important data on the use of biostymulators in the<br />
wheat crop, the concentrations used and biophases<br />
on application.<br />
Analyzing the influence of biostymulators<br />
on the production of wheat, the variety Boema,<br />
was found (table 1), in the year 2009-2010, was<br />
more favorable wheat, achieving higher production<br />
than in 2008-2009. In the year 2008-2009<br />
biostymulators BCO-2K determinated highest<br />
yield of wheat, 5055 kg, with 355 kg/ha higher<br />
than control variant (BCO-4DMA), difference is<br />
significant distinct. Comparated with treated water<br />
variant to production difference was very<br />
significant, of 800 kg /ha.<br />
In 2009-2010, the highest yield was obtained<br />
with biostymulators BCO-2K + zinc acetate, with<br />
5658 kg / ha and a difference from the control<br />
variant of 660 kg/ha, very significant and treated<br />
water variant the difference was 1260 kg / ha.<br />
In 2010-2011 most agricultural production<br />
was obtained in variant BCO - 2 K + zinc acetate,<br />
with 8416 kg / ha, to water treaty variant the<br />
difference is very significant, 2014 kg/ha.<br />
Averaged over three years, biostymulators<br />
BCO-2K + zinc acetate achieved a production of<br />
6322 kg/ha, with a very significant difference of<br />
1311 kg/ha, followed by BCO-2K to 1141 kg/ha,<br />
difference from control variant is a very significant<br />

Due to their biologically active properties, polyphenols convert waste into attractive sources for the medical and<br />
pharmaceutical products, their traditional management being varied towards other technological processes. The<br />
identification of active principles derived from the polyphenolic extracts obtained from pressed grape marc can help<br />
create an alternative use and recovery of by-products of wine, fact which increases their economic value. It also helps<br />
assess the oenological potential of vine varieties and thus to assess their beneficial properties in maintaining metabolic<br />
balance and health of the human body. In this context, the research in this paper aim to characterise the extracts<br />
obtained from pressed grape marc by identifying and quantifying the major polyphenolic compounds in their<br />
composition. To study the influence of the maceration technology on the content of polyphenolic compounds from byproducts<br />
of the winemaking process, grape samples of Fetească neagră, Băbească neagră, Cabernet Sauvignon, Merlot<br />
and Arcaş grape varieties were processed using classical maceration, thermo-maceration, microwave maceration and<br />
rotary tanks maceration (ROTO-tanks). The obtained polyphenolic extracts were analyzed by high performance liquid<br />
chromatography (HPLC), several phenolic acids, stilbenes (trans-resveratrol) non-hydrolysable tannins (catechin and<br />
epicatechin), some flavones (rutin and quercitin), and a number of anthocyan compounds being identified and<br />
quantified. The results of the preliminary characterization showed quite similar values in the content of total<br />
polyphenols and tannoid matters index. The maceration variants did not affect the amount of hydroxybenzoic and<br />
hydroxycinnamic acids. The other polyphenolic compounds that were identified varied depending on the grape variety<br />
and maceration technology used. The obtained data justifies the use of pressed grape marc as raw material to obtain<br />
polyphenolic extracts, recommending further research on its biologically active properties (antiradical, antioxidant,<br />
cytotoxic and cytostatic).<br />
Key words: grapes, macerationa, pressed grape marc, extracts, polyphenols<br />
The use of plant extract as remedy source<br />
for different diseases has been an issue since the<br />
beginning of human medicine.<br />
The results of numerous studies show that<br />
the biggest part of active biologic compounds are<br />
polyphenols, a class of over 8000 compounds, out<br />
of which the majority have been identified in<br />
different anatomic segments of plants<br />
(C. Georgescu et al., 2005).<br />
Certain plants have the capacity to<br />
accumulate polyphenolic compounds belonging to<br />
one or two classes, as hydroxycinnamic derivates<br />
and anthocyans in cherries (C. F. Timberlake,<br />
1981; B. Möller et al., 1983). On the other hand,<br />
grapes store complexes mixtures of polyphenolic<br />
compounds, the distribution of the various<br />
polyphenolic compounds in chemical classes being<br />
almost complete (Wilfred Vermerris et al., 2006).<br />
In the specific literture, studies concerning<br />
1 University of Agricultural Sciences and Veterinary Medicine Iasi, Romania<br />
2 Oenological Research Center of Romanian Academy – Iasi branch<br />
the biological activity of some polyphenolic<br />
compounds of different species are found, in tests<br />
in pure form or as fractionate or global extracts<br />
(L.H. Yao et al., 2004; A. Mittal et al., 2003;<br />
O.Vitseva et al., 2005; C. Savin et al., 2009; V.<br />
Katalinic et al., 2010).<br />
The multitude of data in literature regarding<br />
this theme is shadowed by the difficulty in efficient<br />
systematisation, because of the extremely varied<br />
experimental methodology, sources and methods<br />
of obtaining polyphenolic extracts and last but not<br />
least, their concentration and stability in time<br />
(Maria Escribano – Bailon et al., 2003).<br />
In the case of grapes, the polyphenolic<br />
compounds are mostly found in the seeds and skins<br />
of the berries, from where they reach the must and<br />
wine, following maceration (C. Ţardea et al., 2010;<br />
P. Ribereau-Gayon et al., 2006). Among other byproducts<br />
of the wine-making process, the pressed
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
grape marc, due to its physical-chemical<br />
composition, represents an important source of<br />
polyphenolic compounds (L.M. De Campos et al.,<br />
2008; D. Kammerer et al. 2004; G. Ruberto et al.,<br />
2007).<br />
The pressed grape marc is the fermented or<br />
non-fermented residue obtained after pressing<br />
fresh grapes, its chemical composition being<br />
similar to that of the grapes, with some differences.<br />
The fresh (unfermented) grape marc contains 37 -<br />
39 % skins, 1,0 - 1,2 % stems; 0,20 - 0,25 % green<br />
masses (leaves, shoots); 30 - 32 % pulp, 28 - 29 %<br />
seeds, while the wet fermented pressed grape marc<br />
has 25 % skins, 13 % stems; 12 % seeds (N.I.<br />
Razuvaev, 1980). The present study aims at<br />
creating an alternative mean of use for the pressed<br />
grape marc, as polyphenolic extracts, upgrading<br />
thus its economic value.<br />
MATERIAL AND METHOD<br />
The polyphenolic extracts were obtained from<br />
pressed grape marc from the processing of Fetească<br />
neagră, Băbească neagră, Cabernet Sauvignon,<br />
Merlot and Arcaş grape varieties. In order to study the<br />
influence of the maceration technology on the content<br />
of polyphenolic compounds, classical maceration,<br />
thermo-maceration, microwave maceration and<br />
ROTO-tanks maceration were used on the grape<br />
samples. Because of insufficient quantity, the Arcaş<br />
grapes were processed only by classical maceration<br />
technology. 17 samples of pressed grape marc were<br />
obtained (one sample for Arcaş and four samples<br />
each for each grape variety, according to the used<br />
maceration procedures). After drying and grinding (1-<br />
30<br />
2 mm) the vegetal materials were treated with ethylic<br />
ether. The extraction procedure was done in a<br />
continuous system by using the Soxhlet device,<br />
having as solvent ethanol ratio 1/10 (vegetal material<br />
(g)/solvent (mL). The time span of the process varied<br />
according to the necessary time for draining of the<br />
vegetal material (48 – 72 hours), with a constant<br />
temperature of 78°C.<br />
In order to characterise the phenol extracts,<br />
the total polyphenols were determined using the<br />
Folin-Ciocalteau method as well as the tannoid<br />
matters index (I.M.T) using the method established by<br />
Bourzex. HPLC analysis (high performance liquid<br />
chromatography) identified and quantified a series of<br />
pehnolic acids, stilbens (trans-resveratrol), nonhydrolisable<br />
tannins (catechin and epicatechin), some<br />
flavones (rutin and quercitin), as well as a series of<br />
anthocyan compounds.<br />
RESULTS AND DISCUSSIONS<br />
The data obtained during the process of the<br />
characterisation of the studied polyphenolic<br />
extracts is presented in table 1. The analysis of the<br />
results shows relatively close values of the total<br />
polyphenolic content and tannoid matters index,<br />
indifferent of the grape variety. Within the same<br />
variety, a reduced influence is that of the<br />
maceration technology of the polyphenolic content.<br />
Therefore, the thermo-maceration and<br />
microwave maceration extract the lowest quantity<br />
of polyphenols in wine, the pressed grape marc<br />
being thus richer in polyphenolic compounds.<br />

The anthocyans were below the detection<br />
limit in the samples obtained by classical<br />
maceration and ROTO-tanks maceration (example
Cabernet Sauvignon and Băbească neagră<br />
samples). For the other extracts, the anthocyans<br />
content was reduced, varying from 0.875 to 11.375<br />
mg/L. The extracts from Merlot showed low<br />
quantities of anthocyans, in all maceration<br />
methods. This can be because of the low content of<br />
anthocyans of the grape samples used in the<br />
experiment.<br />

31<br />

hydroxybenzoic and hydroxycinnamic acids. One<br />
notices that vanillic acid is predominant (figure 1),<br />
with lowest values in Babeasca neagra extract<br />
(0.816 mg/L) and Cabernet Sauvignon extract<br />
(0.857 mg/L), and highest in Merlot (2.240 mg/L)<br />
and Arcaş extract (2.174 mg/L). The most frequent<br />
hydroxybenzoic acid, gallic acid, did not vary<br />
significantly regarding the grape variety, having<br />
values from 0.345 mg/L (Cabernet Sauvignon) to<br />
0.663 mg/L (Arcaş).<br />
Figure 1 Variation of the hydroxybenzoic acids’ content identified in the polyphenolic extracts<br />
obtained from the pressed grape marc<br />
Comparing the extracts obtained from seeds<br />
and skins and the extracts obtained from pressed<br />
grape marc, in the latter the m-hydroxybenzoic<br />
acid was not identified, being probably degraded<br />
during the maceration process.<br />
The salicylic acid could not be well<br />
evidenced, because of tannin interference. Gentisic<br />
acid, formed during the fermentation process, was<br />
found only in the extracts from Merlot.<br />
Regarding the maceration methods, it was<br />
registered that they do not influence the quantity of<br />
the hydoxybenzoic acids from the polyphenolic<br />
extracts. So, the predominant hydroxybenzoic acid<br />
in the case of all the samples obtained by the four<br />
maceration methods was the vanillic acid (figure<br />
2).<br />
From the hydroxycinnamic acids, only the pcumaric,<br />
ferulic and clorogenic acid were<br />
identified in the polyphenolic extracts (table 2).<br />
Cafeic acid was identified only in Arcas<br />

Besides the phenolic acids, in the<br />
polyphenolic extracts, trans-resveratrol was<br />
analysed as well (figure 3). It is one of the main<br />
active principles, determining the bioactive values<br />
of the extracts.<br />
The data in figure 3 show that the thermomaceration<br />
sample has the highest content of trans<br />
– resveratrol in the case of the polyphenolic<br />
extracts obtained from the pressed grape marc of<br />
the Fetească neagră, Cabernet Sauvignon and<br />
Băbească neagră grape varieties. The extract<br />
obtained from Merlot and Arcaş, trans – resveratrol<br />
is predominant in the classical maceration samples.<br />
The HPLC analysis of the polyphenolic extracts<br />
showed the presence of non-hydrolysable tannins,<br />
such as catechin and epicatechin.<br />
32<br />
The catechin content from the pressed grape<br />
marc extracts varies between 0.8 mg/L in the<br />
Cabernet Sauvignon extract, to 15.2 mg/L in the<br />
Merlot extract. These values represent the same<br />
maceration technology, the classical one.<br />
In the case of epicatechin, higher quantities<br />
were identified in the extract from Fetească neagră<br />
and Merlot (figure 4).<br />
Other identified active principles from the<br />
polyphenolic extracts of the pressed grape marc<br />
were rutin and quercitin (table 3).<br />
The extracts obtained from the Feteasca<br />
neagră pressed grape mark are registered, with an<br />
average content of 6.54 mg/L rutin and 2.52 mg/L<br />
quercitin as well as that of Arcaş with 5.58 mg/L<br />
rutin and 2.05 mg/L quercitin.

CONCLUSIONS<br />
The study of the extracts obtained from<br />
pressed grape marc underlined the presence of<br />
non-hydrolysable tannins (catechin, epicatechin)<br />
and of flavones (rutin) in important quantities.<br />
The phenolic acids and the trans –<br />
resveratrol were identified in low quantities,<br />
having subunit values, except vanillic acid.<br />
The maceration variants used (classical<br />
maceration, thermo-maceration, microwave<br />
maceration and ROTO-tanks maceration) does not<br />
significantly influence the polyphenolic<br />
compounds content’ from the pressed grape marc.<br />
The identified active principles stand proof<br />
for the use of pressed grape marc for obtaining<br />
polyphenolic extracts. An alternative use of the byproducts<br />
of the wine-making process is created,<br />
increasing their economic value.<br />

GEOMORPHOLOGICAL AND LITHOLOGICAL FEATURES<br />
OF PEDOGENESIS AND SPACE DISPERSAL OF CHERNOZEMS STAGIC<br />
IN REPUBLIC OF MOLDOVA<br />

As a result of large-scale soil research in Central part of Republic Moldova was established that chernozems stagnic are<br />
spread on the uniform horizontal surfaces of the river Răut basin or on the inconsistent interfluvial hills, lithological<br />
substrate of which is represented by clays. Landscape elements that formed these soils are the primary denudation areas<br />
that outcome of raising Alpine territory nowadays occupies absolute altitudes of 200-250 m. Pedogenesis of stagnic<br />
chernozems determined by non salinization clay texture of parental rocks. Chernozems stagnic differ from the zonal<br />
chernozems by presence of a gleyic horizon in the lower bioaccumulative layer, clay texture, higher cation exchange<br />
capacity and humus content. They have a high fertility potential, but not always give the corresponding results due to air<br />
– humidity regime in the years with abundance rainfall or due to hard tillage during the dry autumns.<br />
Chernozems stagnic are a difficulties object for use in arable. In view of risk the stagnic chernozems are capability,<br />
primary for perennial grasses, apple and plum plantation, if the gleyic horizon is located deeper than 70-80 cm;<br />
secondary – for winter grain crops: in the third – for weeding crops. Chernozems stagnic tillage is recommended only to<br />
corresponding humidity of soil physical maturity. Average soil rating of chernozems stagnic consists 85 points.<br />
Key words: chernozem stagnic, clay texture, gleyic horizon, pedogenesis<br />
Soil water stagnation is a phenomenon of<br />
keeping in the soil or the soil surface an excess of<br />
water from precipitation, present above an<br />
impermeable layer, which usually is a soil horizon.<br />
In Republic of Moldova specific researches to<br />
assess genesis, nomenclature and classification of<br />
stagnic chernozem gleyic in depth were not<br />
performed. These soils occupy horizontal surfaces<br />
draining on local interfluvial heights (Чербарь<br />
В.В., 2007b). Stagnic chernozems are not<br />
highlighted in the existing system of classification<br />
and evaluation, and their genetic and production<br />
features are not studied. On the previous maps, the<br />
surfaces of stagnic chernozems were incorrectly<br />
entered into the zonal land areas. Concomitant<br />
incorrectly was calculated the rating note and their<br />
suitability for different agricultural use. No<br />
highlight the chernozems stagnic on the map can<br />
be explained by the fact that in the Russian<br />
naturalist classification used in the country, stagnic<br />
soils are not present (Cerbari V., Leah T., 2010,<br />
Leah T., 2010b, Чербарь В.В., 2007a).<br />
Stagnogleic aquatic properties of soils<br />
formed as a result of wetting stagnic character are<br />
used as a diagnostic properties system of soil<br />
classification FAO UNESCO (Почвенная карта<br />
мира, 1990) and in the last Romanian system of<br />
soil taxonomy (2003). These properties relate to<br />
soil material that continuously or periodically are<br />
saturated with water from precipitation and which<br />
present manifestations of the reduction and<br />
segregation of iron and have a specific color.<br />
The Romanian system of soil taxonomy<br />
emphasizes the need to distinguish between<br />
pedogenesis and geological gleyzation. The first is<br />
a biochemical process that in addition to water<br />
saturation is conditioned by the presence of<br />
organic matter, temperature higher than 0° and<br />
favorable reaction conditions to development<br />
reducing microorganisms. Pedogenesis gleyzation<br />
- is standing on the bases of the bioaccumulative<br />
horizon. Gleyzation in the deeper layers of soil and<br />
subsoil is relict and determined by geological<br />
processes as soon as soil. Stagnic soil properties<br />
into the Romanian system of taxonomy are<br />
separated at the stagnosoils type as the class<br />
“hydrosoils”.

MATERIALS AND METHODS<br />
Research objects are chernozems stagnate<br />
spread on the wide interfluvial peaks within Raut river<br />
basin, the absolute altitude 200-250 m (profile 5 and<br />
6) and parallel ordinary chernozems (profiles 7 and 8)<br />
on the same sole and altitudes:<br />
Profile 5. Chernozem stagnic, humifere,<br />
weakly carbonate, gleyic in depth, clay, arable (village<br />
Chiştelniţa);<br />
Profile 6. Chernozem stagnic, humifere,<br />
semicarbonatic, gleyic in depth, clay, arable (village<br />
Ordasei);<br />
Profile 7. Chernozem ordinary, humifere,<br />
semicarbonatic, clay-loamy, arable (village Ordasei);<br />
Profile 8. Chernozem ordinary, moderate<br />
humifere, semicarbonatic, loamy-clay, arable (village<br />
Chiştelniţa).<br />
Stagnogleic pedogenesis processes are<br />
widespread in soils of Moldova. Anagogic soils are<br />
also found in other parts of the country, but most<br />
commonly spread of stagnic chernozems is<br />
characteristic for that territory.<br />
Collection of samples was performed on the<br />
quasi horizontal areas of watershed located adjacent<br />
to the river valley. For all profiles was performed<br />
morphological description, soil sampling of on genetic<br />
horizons, determination of apparent density for Ahp1,<br />
Ahp2, Ah horizons (up to 50 cm of depth). The soil<br />
samples were performed using the analysis required<br />
by existing conventional classic methods.<br />
REZULTATE ŞI DISCUŢII<br />
Geomorphologic and lithological features<br />
of soil formation and dispersal space of<br />
Chernozems stagnic in r. Rãut basin<br />
Chernozems stagnic of river Rãut basin in<br />
Central Moldova are spread over uniform surfaces<br />
(horizontal) or weak inconsistent interfluvial<br />
peaks, lithological substrate of which is<br />
represented by clays. Landscape elements that<br />
formed these soils are the primary areas of<br />
denudation that outcome of raising Alpine territory<br />
now occupies absolute altitudes 200-250 m<br />
Pedogenesis of stagnic chernozems mostly is<br />
determined by clay texture of the parental rock.<br />
Clay on the plateaus differs from marine clay, that<br />
appearing on the slopes, the lack of salinization. It<br />
is possible limnisch or alluvial - limnic origin of<br />
this clays. Information on the geological structure<br />
of territory located in the basin of river Rãut,<br />
where soil samples were collected for research is<br />
very limited in volume.<br />
According to geological research, at the end<br />
of the Pliocene on the territory of Central and<br />
Southern Moldova is established the continental<br />
climate regime, forming alluvial plain, sedimentary<br />
deposits which were now preserved only on the<br />
highest elevation areas of relief (Покатилов B.,<br />
1983). Leveled surface sediments are particularly<br />
36<br />
altered psammyte-clay deposits of lakes and<br />
lagoons with low water level. In composition of<br />
clays mainly prevails the montmorillonite deposits.<br />
Most clay rocks are dense and the composition of<br />
chlorito-montmorillonito-hydromicaceous<br />
(Геоморфология Молдавии, 1978).<br />
Contemporary relief formation was based on<br />
alluvial-limnic plain of Pliocene which served as<br />
the original initial surface. In Moldova the alluvialdelta<br />
plains of the middle Pliocene replaced marine<br />
deposits of Middle Sarmatian. Composition of<br />
deposits shows a weakly fragmented landscape.<br />
Fauna was found in the middle Pliocene<br />
(mastodons, rhinoceroses, etc.) proves in favor of a<br />
savanna landscape type and a warm climate<br />
interspersed with high humidity phase (Билинкис<br />
Г., 2004). Morphogenesis at the stage between<br />
middle Pliocene and Pleistocene is characterized<br />
by periodic changes of cold and warm climate<br />
cycles. The same time is initiated delta formation<br />
of a powerful flood flow and wide floodplain<br />
associated with lakes and moods.<br />
In late Pliocene and Eopleistocen stands<br />
gradual lifting of the territory, dividing unique<br />
river into two large flows. In the Pleistocene<br />
tectonic movements are amplified, forming<br />
mountains with small altitudes of the woods,<br />
named “Codri”; is born contemporary river<br />
network. At the same time is formed Dniester<br />
Plateau, its ramifications constitutes is watershed<br />
on surfaces which have been studied soil profiles<br />
(Билинкис Г., 2004).<br />
River Rãut during his middle and upper<br />
Sarmatian discovered lower sublevel deposits of<br />
(N1S1), which are represented by calcareous rocks,<br />
marl and clay, less commonly sandstone.<br />
Currently sedimentary deposits on the<br />
surface of Rãut river basin is a complex of<br />
Pliocene-Quaternary eluvial formations non<br />
disrupted on the surface of watershed and early<br />
river terraces (eN2-Q); upper Quaternary<br />
formations of contemporary eluvial-deluvial<br />
deposits, etc. (Атлас Молдавской ССР, 1978).<br />
Geological research confirms origin of<br />
alluvial-limnic of clay that formed the chernozems<br />
stagnic on the local interfluvial peaks in Rãut river<br />
basin. Bottom part of soil profiles formed on clays<br />
is temporarily saturated in stagnant rainwater and<br />
presents events gleyzation processes. Properties<br />
stagnic correlate with provided aquatic condition<br />
of "episaturation" defined as soil water saturation<br />
in one or more layers (horizons) in the first 200 cm<br />
of mineral soil surface. Saturation zone is<br />
composed of water suspended from a relatively<br />
waterproof layer. Stagnogleic properties are note<br />
with the "g" when color reduction-oxidation up to<br />
50% of the gleyied horizon and “G” when the
color reduction - oxidation occupies over 50% of<br />
the surface horizon (Leah T., 2010a).<br />
In the field mostly areas of clay stagnic<br />
chernozems are adjacent to areas with zonal<br />
chernozems with texture - loamy and sandy loam,<br />
located at slightly higher altitudes. All these<br />
affirmations confirm the alluvial-limnic origin of<br />
deposits that have formed these soils.<br />
Genetic characteristics and properties<br />
of Chernozems stagnic located in the zone of<br />
ordinary chernozem, altitude 200-250 m<br />
Morphometric indices include data on<br />
thickness and morphology of the genetic horizons<br />
of investigated soil profiles (tab. 1).<br />
Parental rocks are limnic deposits formed in<br />
Pliocene. Profile depth - 160 cm. Effervescence -<br />
from 30 cm. Carbonates as veined - from 60 cm<br />
and bieloglasca - from 75 cm to 142 cm. Profile<br />
have genetic horizons: Ap1 - Ap2 - Ah - AB - BG -<br />
BG - BCG-Cg – C. Gleyzation start at 75 cm, high<br />
gleyzation - from 125 cm (fig.1, 2).<br />
Comparative analysis of morphometric<br />
indices and morphological characteristics of the<br />
studied profiles of chernozems stagnic gives<br />
opportunity to make the following conclusions:<br />
The thickness of the humus profile varies<br />
from 80 cm up to 100 cm.<br />
Horizon Ah and/or ABh is distinguished by<br />
black pronounced gloss aggregates faces<br />
In basis of humus profile outlined a clay<br />
horizon, marl, gleyic, well developed, which<br />
also is a horizon of carbonate accumulation<br />
as bieloglasca.<br />

Texture Pedogenesis of chernozems stagnic<br />
is determined by clay texture of the parent rock.<br />
Physical clay content in investigated soils varies<br />
from 70% to 80% and clay - from 48% to 57%.<br />
The fine texture is characteristic for parental rock.<br />
Physical clay content in the underlying horizons of<br />
the profiles is 76-79% and clay - 53-57%. The high<br />
percentage of clay in the parent material can be<br />
formed only in alteration of underwater rocks in<br />
warm weather conditions. Size composition of<br />
parent material that is formed alluvial chernozem<br />
stagnic confirms origin alluvial-limnic of late<br />
Pliocene, established by geological research<br />
During normal hydrothermal regime in<br />
early spring crumb structure with small aggregates<br />
and fluffy state of arable layer of chernozem<br />
stagnic ensures the possibility of soil material to<br />
destroy in the contrasts of temperature and wetting<br />
conditions. The references often indicate that soils<br />
with high clay content are vertic soils. Case studies<br />
show that not all vertic processes can be assessed<br />
by high clay content in soil (Крупеников, 1990).<br />
Ordinary chernozem (profile 7, 8), located<br />
on the same plots with chernozems stagnic
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
(polygon 5, 6), is characterized by loamy-clay<br />
texture. Texture of these soils differs from<br />
chernozems formed on the loess by a high<br />
percentage of sand, as a result of joint aerial global<br />
accumulation process of loess deposits with local<br />
process of deflation of Pliocene alluvial deposits,<br />
sometimes spread over the highest peaks.<br />
High content of sand, in the recent<br />
destruction of the arable layer of typical<br />
chernozems, provides for clayey, sandy-clay soils<br />
more favorable physical and mechanical<br />
properties, which gives way to more easily work<br />
the soil and create a favorable germinating bed<br />
crops in any year. Completely different situation is<br />
characteristics for clay chernozem stagnic.<br />
Structural composition Chernozems<br />
stagnic clayed have high content of fine clay in<br />
years with wet autumn is tillage comparatively<br />
easy. As a result of frost and thaw arable layer is<br />
structured, which gives way to accumulate large<br />
reserves of water in the soil and create a favorable<br />
germinating bed of spring crops. Also these soils<br />
are resistant to spring drought.<br />
In the end of summer and dry autumn,<br />
because the blocks structure, loamy stagnic<br />
chernozem working very hard, plowing on these<br />
soils is extremely rough, creating a favorable<br />
germinating bed is impossible both for winter<br />
crops and for the spring (fig.3).<br />

Territory of Chiştelniţa, Telenesti;<br />
a) - blocks structure, b) - cracks on the surface<br />
During heavy rainfall, due to high water<br />
field capacity, these soils dries hard and slowly<br />
reach physical maturity status. As a result the<br />
rhythm of agricultural work is disturbing with bad<br />
consequences for crop yields.<br />
Physical characteristics Average statistics<br />
data confirm that chernozems stagnic clay is<br />
characterized by high values of the hygroscopic<br />
coefficient within the limits of 7-12%. So in the<br />
soils the high water reserves are also inaccessible<br />
to large plants.<br />
Density average statistical values of soil<br />
material are ranges: from 2.62 to 2.65 in stagnic<br />
humifere horizons, up to 2.70 to 2.75 in gleyied<br />
38<br />
clayey underlying layers. The density of these<br />
horizons is comparatively low due to the high<br />
content of humus.<br />
A full index of physical quality status of the<br />
soils is apparent density. The values of this<br />
indicator for investigated soil profiles range from<br />
1.20 to 1.30 g/cm³ in the arable layer of<br />
chernozems stagnic to 1.50 to 1.60 g/cm³ in<br />
gleyied clay parent rock. Total porosity, while it is<br />
large in arable layer of these soils and very low in<br />
the underlying gleyied layers.<br />
Apparent density values for arable layer<br />
within 1.1 to 1.3 g/cm³ to consider optimal. So,<br />
stagnic arable layer of chernozems are<br />
characterized by comparatively favorable physical<br />
properties and underlying gleyied layers - the<br />
physical unfavorable attributes.<br />
Generally, in terms of texture and physical<br />
properties, chernozems stagnic are a difficult<br />
object for use in arable both in dry years and in<br />
years with heavy rainfall.<br />
In the normal hydrothermal regime of<br />
chernozems stagnic the arable layer in early spring<br />
in some extent can be seen as too loose and then,<br />
after sowing requires easy rollers.<br />
In years with dry autumn is hard to work<br />
these arable soils and crushing layer to create a<br />
favorable germinating bed.<br />
In years with abundant rainfall during the<br />
vegetation period growing danger to forming in<br />
these soils an aerobic deficit regime.<br />
Long term preservation of favorable state of<br />
physical quality of stagnic chernozems is possible<br />
through measures that would help ensure<br />
continuous flow of organic matter in arable layer<br />
of their soil for forming an agronomic valuable<br />
structure.<br />
Chemical and physical-chemical<br />
characteristics The studied soils are characterized<br />
by a neutral reaction from the surface horizons (pH<br />
= 6.9-7.3) and underlying horizons slightly alkaline<br />
(pH = 7.8 to 8.3). For gleyic horizons there is a<br />
trend towards a slightly alkaline reaction than the<br />
surrounding horizons. Surface horizons of<br />
chernozems stagnic are decarbonatat or weak<br />
carbonate. Maximum carbonates content are<br />
characteristic for gleyic horizons and altered<br />
material of limestone rocks, shown in clays, profile<br />
5, 6 (Leah T.,2010b, Leah T.,2011).<br />
Investigated soils are low content of<br />
phosphorus. Total phosphorus content in the<br />
profile is range from 0.10 to 0.11% in arable layer<br />
to 0.05 to 0.06% in the parent rock.<br />
Humus content (statistical average) in<br />
chernozem stagnic equals 4.5 to 4.6% in the Ahp,<br />
3.0 to 3.9% in Ah non plowing, 2-3% in ABh and<br />
1-2% in Bh2. Humus profile ends rather abruptly,
ut the following horizon practically non humifer,<br />
meet black humifer languages, formed as a result<br />

Humifer profile is black; the surface of<br />
aggregates from humifer profile is characterized by<br />
a characteristic gloss anthracite coal.<br />
The C: N in the arable layer and underlying<br />
humus is 10-13. Increases in value ratio C: N in the<br />
underlying horizon, indicating carbonatization of<br />
organic matter in underlying horizons of these<br />
soils. Soils are rich in potassium mobile (30-40<br />
mg/100 g soil) and low in mobile phosphorus (2.0 -<br />
2.5 mg/100 g soil).<br />
Chernozems stagnic have high cation<br />
exchange capacity in the humifer horizons and<br />
middle in the gleyied horizons and parent rock.<br />
There is a gradual increase in depth of the Mg<br />
content. Stagnic chernozems are characterized by<br />
chemical characteristics favorable for plant growth.<br />
Chernozems ordinary investigated parallel,<br />
located on the same plots as stagnic, are<br />
moderately humifer (humus content in arable layer<br />
varies within 3.0 to 3.5%) and is characterized with<br />
lower cation exchange capacity. However, due to<br />
more favorable texture, these soils are more easily<br />
work, by tillage in them creates favorable regimes<br />
for plant growth and as a result, yields on these<br />
soils are higher than on the stagnic chernozems.<br />
The stagnic chernozem productivity<br />
The productivity of chernozems stagnic was<br />
determined by the methods of plots with<br />
surface of 1m² of green mass. In parallel, the<br />
same method was determined harvest level on<br />
zonal ordinary chernozem, spread on the same<br />
area. This made it possible to compare the<br />
productivity of crops on ordinary chernozem<br />
and stagnic chernozems in analogical<br />
agrotechnical conditions (tab.3).<br />
Peculiarities of agriculture 2008: dry autumn<br />
(2007), warm winter with precipitation deficit, dry<br />
spring, drought summer. Soils were plowed<br />
autumn, but autumn drought has not allowed the<br />
work to prepare the soil quality and favorable<br />
germinating bed for crops, particularly on the land<br />
with clay stagnic chernozem that early autumn<br />
arable layer structure turned into blocks. For zonal<br />
ordinary chernozem, soils with coarse texture, they<br />
managed to create a germinating bed.<br />

Assessment of winter wheat harvest was<br />
estimated on the polygon were located the<br />
chernozem stagnic. Also, on the same field, was<br />
determined the yield of winter wheat for zonal<br />
ordinary chernozem (Cerbari V.,Leah T.,2010,<br />
Leah T.,2011, Чербарь В.В.,2007b).<br />
The results of measurements in 5 repetitions<br />
on the surface of 1 m² plots was established that<br />
the winter wheat crop is 27.4 q/ha on the<br />
chernozems stagnic and for the same ordinary<br />
chernozems - 32 q/ha, with 14 -15% higher.<br />
Corn harvest on these soils was only 15.8<br />
q/ha, on the ordinary chernozems on the same lot –<br />
35 q/ha, 55% higher.<br />
Given the fact that agrotechnical factors less<br />
influenced crop yields on investigated soils was<br />
consider that the difference in harvest of winter<br />
wheat on zonal and stagnic chernozem can be used<br />
in calculating the rating note of chernozems<br />
stagnic, which can be assessed about 85 points.<br />
CONCLUSIONS<br />
Chernozems stagnic differ from the typical<br />
area of zonal soils by the presence of a gleyic<br />
horizon in the lower part of bioaccumulative layer,<br />
clay texture, higher cation exchange capacity, high<br />
humus content.

Gleyzation in profile is distinguished at the<br />
depth 50-100 cm from the surface, gleyzation<br />
processes occur due to excess moisture derived<br />
from rain water and lead to accumulation of free<br />
iron compounds in gleyic horizon.<br />
Stagnation excess moisture in the lower<br />
profile of chernozem stagnic is subject to their clay<br />
texture. In the cold period the soil clay profile<br />
humidity are gradually and achieve total water<br />
capacity. During warm period water losses by<br />
evaporation in clay soils are not high. Evaporation<br />
leads to loss of water, but only in the top of soils<br />
(0-50 cm), due to low speed of water movement to<br />
surface in the fine textured soil profile.<br />
Dry clay soils leads to their surface cracks of<br />
3-7 cm. Cracks are important in the genesis and<br />
hydric regime of these soils. During summer heavy<br />
rains the surface water flows through cracks,<br />
leading to maintain excess water in the bottom of<br />
the soil profile. In drought years, when the cracks<br />
are wide and deep in the bottom of soil profile<br />
penetrates (flows) humus material from the upper,<br />
leading to the formation of a transitional nature<br />
glossic horizon with humifer “languages”.<br />
Stagnic chernozems have a high potential for<br />
fertility, but not always give the corresponding<br />
results due to aerohydric defective regime during<br />
heavy rainfall or due to issue their work in years<br />
with dry autumn.<br />
Chernozems stagnic are a difficult object for<br />
use in arable, in years with dry autumns, because<br />
of the structure in blocks of arable layer is hard to<br />
create a germinating bed for autumn crop quality.<br />
In years with dry spring these soils, resulting in<br />
high field capacity water, are resistant to drought,<br />
but if drought is prolonged and summer, spring<br />
crop harvest may be lost.<br />
In terms of risk stagnic chernozems are<br />
suitable: I – for perennial grasses, apple and plum<br />
plantation, if the gleyic horizon is located deeper<br />
than 70-80 cm, II – for winter grain crops, III – for<br />
weeding crops.<br />
During normal hidrotermic regime the<br />
harvest crops on these soils differs little from that<br />
of the zonal soil and is only 10-15% less.<br />
Tillage of chernozems stagnic is advisable to<br />
work only to appropriate humidity of soil physical<br />
maturity. Average rating note of chernozems<br />
stagnic is 85 points.<br />
For chernozems stagnic gleyied in depth<br />
were developed a set of measures and<br />
recommendations, performing and implementation<br />
which will have both economically and<br />
40<br />
environmentally effect, will lead to long-term<br />
preservation of their quality status and increase<br />
their production capacity at least 20%.<br />

In this paper we propose to determine the number of tubers / nest from three potato varieties grown in organic<br />
conditions Bivolari micro area, village Trifesti The experience was located within Agricole Society Trifesti Astra,<br />
company standard of agriculture in Romania. From a climate perspective, the area is characterized by cold winters and<br />
hot summers.It was installed on trifactorial experiences in 3 repetitions of the type 4Ax3Bx2C, being studied five<br />
varieties of potato. In this paper we present partial results of three varieties Factors are studied, A Factor – Foliar<br />
fertilizing, with graduations, a1- not fertilized,a2 – NPK,a3- ECO 1,a4- ECO 2, B Factor– Foliar fertiliozing : b- Adora<br />

Potato (Solanum tuberosum L.) is grown on<br />
every continent, but particularly in Europe, which<br />
has about 50% of the world. (Bîlteanu Gh, 2001)<br />
Potato is given great importance both in<br />
Romania and globally.<br />
In Romania in 2010 cultivated area reached<br />
246,982 ha, but in 2009 was peaked at 260,317<br />
ha.<br />
In to the production is noted that in 2010<br />
3,283,870 tons were produced in 2009 was peaked<br />
at 4,003,980 t.<br />
The amount of boiled potatoes 200g body<br />
provides 16-18% of protein for 24 hours.<br />
Composition of potato protein has a broad<br />
spectrum of essential amino acids and free, the<br />
most important of which are tryptophan, lysine<br />
and isoleucine. (Berindei M., 1995)<br />
In this research have been studied three<br />
varieties of potato, as follows: VELOX, which is<br />
a kind of high production, very early, and french<br />
fries consumption.<br />
The variety has large tubers, long oval<br />
yellow shell, smooth, very beautiful, ideal for<br />
washing and packing.<br />
It is a resistant variety Wart race 1, UCP Ro<br />

Potato is one of the most important crops,<br />
which have a high ecological plasticity, is grown<br />
on all continents, in over 140 countries, which are<br />
grown mainly for food, but also for industrial and<br />
animal feed.<br />
For human food potato occupies the fourth<br />
place in the world after wheat, rice and corn,<br />
using fresh or as dried and cooked.<br />
It was studied and a the Netherlands potato.<br />
Potato is an important crop for Netherlands<br />
agriculture industry.<br />
It occupies almost one quarter of the<br />
country's arable land and nearly half of total
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
production value achieved on farms with arable<br />
land (van der Zaag, 1992)<br />
MATERIALS AND METHODS<br />
The research was conducted in 2011 in SA<br />
Astra Trifesti, village Trifesti, the micro Bivolari who<br />
are in an area with temperate climate and is<br />
characterized by cold winters and hot summers with<br />
irregular winds, more frequent in the north-west and<br />
north - winter and south-east and east - especially in<br />
spring, sufficient rainfall - especially in early summer.<br />
For realization of this study, we used three<br />
varieties of potato.<br />
In this micozonă, 5% of the area is planted<br />
with potatoes, from which most of them remains with<br />
the company Astra Trifesti.<br />
Experience is trifactorial carried out in three<br />
repetitions of type AxBxC being studied five varieties<br />
of potato. We present partial results of the three<br />
varieties.<br />
The factors studied are:<br />
Factor (A) – fertilization:<br />
- a1- nefertilizat<br />
- a2 - NPK<br />
- a3- ECO 1<br />
- a4- ECO2<br />
Factor (B) – variety:<br />
- b1- Adora A, România – martor<br />
- b2 - Adora E, Olanda<br />
- b3- Velox A, România<br />
Factor (C) – ecological vegetation herbicide<br />
treatment:<br />
- c1- treatment with Novodor ( 4l/ha)<br />
- c2 -treatment with NeemAzal(2l/ha)<br />
At harvest were sampled to determine the<br />
number of tuber-nest all 4 variants, in three<br />
repetitions of the three varieties.<br />
Using ecolologice products is a plus because<br />
the trend worldwide is expanding and the demand<br />
for agricultural products is growing.<br />
Statistical data processing was performed<br />
using analysis of variance. This paper presents the<br />
results obtained from potato varieties studied in 2011<br />
RESULTS AND DISCUSSION<br />
Regarding the influence of fertilization<br />
treatments and analyzing data in Table 1 kind<br />
notice that the largest number recorded in the<br />
variant fertilized tubers classic variety Adora is<br />
the difference from the control is 276.42%.<br />
42<br />
With regard to organic fertilization, it<br />
appears that the version which applied ECO1<br />
ecological product, number of tubers per nest<br />
tubers increased very significantly from the<br />
control,% 171.82% as compared to the control the<br />
variety Adora E.<br />
Using organic products was beneficial<br />
recorded significant increases in the number of<br />
tubers per nest in all varieties that have been<br />
applied.<br />
From Table 2 the shows that in both of<br />
which have used these products have obtained<br />
increases Relevant to version control, so the<br />
variety is the difference from the control loves<br />
being 164.84%.<br />
All three varieties used have performed<br />
well, both classical fertilization and organic<br />
fertilization<br />
From tables 1,2,3 and 4 shows that the three<br />
varieties used, the volume is performed best. In all<br />
variants of fertilization.<br />
Regarding the influence of variety on the<br />
number of tubers in 2011, is seen from Table 3,<br />
loves the variety that is, to obtain the highest<br />
yield% compared to the control was 112.67%<br />
Analyzing Table 4, it is noted that the<br />
variant fertilized with NemAzal classic<br />
combination to obtain the largest production<br />
increase 210.99%<br />
CONCLUSIONS<br />
The data presented can draw the following<br />
conclusions.<br />
Taking account that the world is putting<br />
great emphasis on using organic products, it is<br />
found that potato and they give a good<br />
performance compared with conventional<br />
products. Two.<br />
Influence of fertilization on the number of<br />
tubers classic in 2011, was manifested by<br />
production increases significantly compared to<br />
version control.<br />
In all three varieties of potato used,<br />
variance analysis by F test, reveals that the<br />
number of tubers per nest was significantly<br />
influenced by classical fertilization and organic<br />
fertilization.

Grapevine fanleaf virus (GFLV) is one of the most severe virus diseases in vineyards worldwide. It causes extensive<br />
leaf yellowing, stem and leaf deformation, reduced fruit quality, substantial crop loss and shortened longevity of<br />
vineyards. GFLV is transmitted specifically from grapevine to grapevine by the ectoparasitic nematode Xiphinema<br />
index, and belongs to the genus Nepovirus in the family Comoviridae. During 2009 and 2011 a sanitary survey was<br />
conducted in the ampelographic collection of the University of Agricultural Sciences and Veterinary Medicine Iaşi<br />
(Romania) on 170 cultivars belonging to Vitis spp. Our objectives were to determine the presence and distribution of<br />
GFLV across the ampelographic collection, and to find out if the virus titre fluctuation is cultivar specific. Leaf samples<br />
were taken during spring season from vines exhibiting virus-like symptoms or general vine decline. Three mature leaves<br />
including the petiole from different sections of the vine, keeping between the first and fifth node from the base of the<br />
vine were collected in dry, cool weather. The results of DAS-ELISA test confirm that virus was present in 29 grapevine<br />
cultivars (17.1% of total) from the ampelographic collection. Infected vine cultivars with the highest OD (optical<br />
density) values were Gordan, Newburger, Cioinic, Galbenă de Odobeşti, Blauerzweigelt and Merlot.<br />
Key words: Vitis spp., GFLV, ELISA, Romania<br />
Grapevine fanleaf virus (GFLV) is one of<br />
the most destructive pathogens of grapevine<br />
worldwide. It causes extensive leaf yellowing,<br />
stem and leaf deformation, reduced fruit quality,<br />
substantial crop loss (up to 80%) and shortened<br />
longevity of vineyards (Andret-Link et al., 2004).<br />
Among 58 virus species that can infect grapevine,<br />
GFLV belongs to the plant virus genus Nepovirus<br />
of the family Comoviridae (Mayo and Robinson,<br />
1996) with genome consisting of two singlestranded<br />
positive sense RNAs, separately<br />
encapsidated (Fritsch et al., 1993, Wellink et al.,<br />
2000). The soil-borne virus is transmitted<br />
exclusively by the ectoparasitic nematode<br />
Xiphinema index Thorne and Allen, which can<br />
survive in vineyard soils and retain GFLV for<br />
many years with or without host plants<br />
(Demangeat et al., 2005; Martelli, 2006).<br />
Vineyards viruses control is currently based<br />
on preventive measures and cultural practices.<br />
Prophylactic measures intend to prevent<br />
introduction of diseased vine varieties in healthy<br />
vineyards, and cultural practices try to reduce the<br />
vectors population (Laimer, 2009). GFLV is<br />
controlled by soil disinfection with nematicides,<br />
but this procedure is only partially efficient and in<br />
many countries forbidden because of<br />
1 University of Agricultural Sciences and Veterinary Medicine, Iasi<br />
environmental toxicity (Demangeat et al., 2005;<br />
Raski and Goheen, 1988).<br />
The aims of this study were to determine the<br />
presence and distribution of GFLV across the<br />
ampelographic collection of University of<br />
Agricultural Sciences and Veterinary Medicine<br />
(USAMV) Iaşi, and to find out if the virus titre<br />
fluctuation is cultivar specific.<br />
MATERIAL AND METHODS<br />
During 2009 and 2011 a sanitary survey was<br />
conducted in ampelographic collection belonging to<br />
USAMV Iaşi (N-E Romania) on 170 genotypes<br />
belonging to Vitis spp.<br />
Leaf samples were taken each year during<br />
spring season from 34 vines exhibiting virus-like<br />
symptoms or general vine decline. Three mature<br />
leaves including the petiole from different sections of<br />
the vine, keeping between the first and fifth node from<br />
the base of the vine were collected in dry, cool<br />
weather. Totally, 368 samples of symptomatic leaves<br />
from surveyed varieties were collected, put into<br />
separate plastic bags, frozen with liquid nitrogen,<br />
transported to the laboratory, and stored at −80ºC<br />
until analysed.<br />
Symptomatic grapevine samples were used for<br />
detection of GFLV by a double-antibody sandwich<br />
ELISA (DAS ELISA) using monoclonal and polyclonal<br />
antibodies. ELISA was performed with commercial
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
kits (ADGEN Phytodiagnostics, UK), according to the<br />
manufacturer recommendation. Crude grapevine<br />
extracts were prepared by grinding 1 g leaves in 10<br />
mL of ELISA extraction buffer. Leaf extracts were<br />
centrifuged at 2,000 g for 15 min and the supernatant<br />
was used as the antigen in DAS ELISA. 100 µL were<br />
loaded in each well on microtiter plates (Nunc<br />
Immunoplate I, Nunc, Denmark). Incubation steps<br />
lasted overnight at 4°C in closed dark boxes.<br />
Reactive were preincubated to the plate temperature.<br />
Intermediate washings were done with<br />
PBS/Tween buffer. Values were recorded measuring<br />
absorbance at 405 nm with a microplate reader<br />
Sunrise (Tecan, Austria) powered by Magellan data<br />
analysis software.<br />
DAS ELISA results were taken as mean<br />
absorbance value of three replicates per sample.<br />
Positive and negative controls were supplied with the<br />
kit. Each value was considered GFLV-positive when<br />
the average value was at least three times greater<br />
than the mean of healthy control.<br />
46<br />
Statistic was performed with Microsoft Office<br />
Excel 2007. Analysis of variance was performed with<br />
the use of One-Way ANOVA test. A P value of less<br />
than 0.05 was considered to indicate statistical<br />
significance.<br />
RESULTS AND DISCUSSIONS<br />
The incidence of GFLV disease on<br />
ampelographic collection of USAMV Iaşi was<br />
visually monitored between 2009 and 2011. Out of<br />
336 grapevine samples collected from 34 varieties<br />
with characteristic symptoms 279 were infected<br />
with Grapevine fanleaf virus. GFLV was present in<br />
29 grapevine cultivars (17.1% of total) from the<br />
ampelographic collection. Foreign grapevine<br />
cultivars showed a higher sensitivity to GFLV in<br />
comparacy with the indigenous grapevine cultivars<br />
(Table 1).<br />

The results show that not all cultivars with<br />
virus-like symptoms are caused by GFLV. Leaf<br />
yellowing, stem and leaf deformation could be<br />
caused by physical injury or some other disorder<br />
(fungicide, herbicide, insecticide). GFLV causes<br />
the grapevine fanleaf degeneration worldwide and<br />
severe losses up to 80%, poor fruit quality and<br />
reduced grapevine longevity (Andret-Link et al.,<br />
2004).<br />
Infected foreign cultivars with the highest<br />
OD (optical density) values measured at 405 nm<br />
were Blauerzweigelt, Merlot and Newburger.<br />
Infection with high OD was also confirmed in<br />
some indigenous cultivars as Gordan, Cioinic and<br />
Galbenă de Odobeşti (Figure 1).<br />
Table 1<br />
Differences in sensitivity to GFLV are<br />
known among cultivars of V. vinifera; some are<br />
resistant to infection and others recover one year<br />
after the appearance of symptoms. A fundamental<br />
importance in the development of the disease is<br />
played by environment and growing area, because<br />
the number of infected grapevines in vine<br />
plantations will increase dramatically in the<br />
presence of infected vineyards.<br />
ANOVA did not reveal statistical<br />
differences among the mean values of extinction in<br />
GFLV-infected cultivars during 2009 and 2011<br />
(data not show).<br />
These results could be used for improving<br />
detection protocols to test grapevine propagative<br />
material in Romania and to eliminate the risk of
long distance spreading during international<br />
exchange of plant material.<br />

CONCLUSIONS<br />
Grapevine cultivars from ampelographic<br />
collection of USAMV Iaşi (N-E Romania) have<br />
been examined by visual symptom assessment for<br />
typical GFLV symptoms between 2009 and 2011<br />
and serological tests (DAS ELISA) revealed that<br />
incidence of GFLV disease ranged 17.1%.<br />
Infected grapevine plants from the 29<br />
varieties should be removed and replaced after<br />
reducing of vector populations. Also, the usage of<br />
clean planting material and surveying the<br />
neighbouring viticulture areas are measures that<br />
should be implemented to maintain the disease<br />
under control.<br />

The study aimed to assess the quality of forages obtained from a permanent grassland of Dorna Depression (Romania)<br />
under the influence of organic versus mineral fertilization. The experiences were monofactorial in three repetitions,<br />
located on a grassland of Nardus stricta L. to follow the effect of fertilization with 20-50 t ha -1 manure, applied annually<br />
or every 2 years and N100P100, N140P140 and N200P200, on the chemical composition of the forage. It was observed for<br />
experience with organic input, crude protein (CP) content increased from 6.38% to 9.32%-13.14%, NDF and ADF<br />
decreased from 74.71% to 50.08%-60.20%, and from 47.09% to 43.11%-37.47%, respectively, and in experience with<br />
chemical fertilization CP increased from 6.48% to 6.59%–14.08% while NDF and ADF, decreased from 72.25% to<br />
59.28%–51.92%, and from 45.64% to 39.79-32.10%, respectively. The values of the investigated parameters indicate an<br />
improvement in forages quality.<br />
Key words: organic input, mineral fertilization, permanent grassland, nutritional value<br />
Permanent grassland area of Romania covers<br />
over 4.8 million hectares, of which more than a<br />
half are located in upland areas and the grassland<br />
area, dominated by Nardus stricta L., covers<br />
300,000 hectares at 400 – 2200 m altitude on acid<br />
soils, replacing more valuable grasslands,<br />
especially those of Agrostis capillaris and Festuca<br />
rubra (Vintu et al. 2011). Permanent grasslands are<br />
an important part of Romania's natural resources.<br />
These grasslands serve multiple purposes which<br />
harmoniously combines many functions that can be<br />
used to benefit people and animals: provide habitat<br />
and food source for animals, protect soils against<br />
erosion, provide biodiversity for at least 70% of all<br />
species of plants, make the beautiful environmental<br />
and also a great part of the biomass can be<br />
converted into unconventional energy. Forages<br />
obtained from these permanent grassland represent<br />
an important source for animals feed due to the<br />
cultivated surfaces and the high yields of good<br />
quality obtained from them (Avarvarei and<br />
Chelariu, 2011). For a long-term period no<br />
elementary management measures were applied on<br />
permanent meadows in Romania, estimating that<br />
they could get efficient yields without<br />
technological inputs. The fertilization of mountain<br />
grasslands with organic fertilizers leads to an<br />

improvement in terms biodiversity, productivity<br />
and quality (Ansquer et al., 2009; Schellberg et al.,<br />
1999). Fertilization with organic and mineral<br />
fertilizers is one of the main means by which we<br />
can increase the yield of permanent grasslands and<br />
have a strong influence on forage quality by<br />
modifications in floristic composition, chemical<br />
structure, consumption and digestibility with<br />
implications on nutritive and energetic values<br />
(Avarvarei and Chelariu, 2011; Păcurar et al.2012;<br />
Štýbnarová et al. 2012).<br />
The first aim of this study was to investigate<br />
the effect of mineral and organic fertilization on<br />
the nutritional value of forages from a permanent<br />
grassland of Nardus stricta L. located in Dorna<br />
Depression (north-eastern Romania). The second<br />
aim of the study was to establish the best dose of<br />
fertilization in order to improve the quality of<br />
forages on the permanent grassland.<br />
MATERIALS AND METHODS<br />
The study was carried out on a Nardus stricta<br />
L. permanent grassland situated at an altitude of 840<br />
m in the Cosna region, Romania. For studying the<br />
influence of fertilization on forages’ quality the<br />
experiments were set up as a random block system in<br />
three replications, with the variants presented in table
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
1. The first experience was in 3 repetitions. The<br />
surface of each variant of fertilization was 20 m 2 (4 ×<br />
5m). The repetition block area was 180 m 2 and the<br />
surface of the experience was 540 m 2 . The second<br />
experience was also in 3 repetitions with the surface<br />
of each variant of fertilization of 20 m 2 (4 × 5m). The<br />
repetition block area was 140 m 2 and the surface of<br />
the experience was 420 m 2 .<br />
The manure with a content of 0.42% total N,<br />
0.19% P 2O 5 and 0.27% K 2O was manually applied,<br />
early in spring, at the beginning of grass growth.<br />
Freshly harvested hay samples were dried in a forced<br />
air-oven at 60°C and milled through a 1-mm screen<br />
for chemical analysis.<br />
The dry matter (DM) of forage was determined<br />
at 105°C for 5 h, crude protein (CB) was determined<br />
by the Kjeldahl method using a device Inkjel P and<br />
distillation Behrotest WD20, Labor Technik,<br />
Germania, ether extract (EE) by the Soxhlet method,<br />
ash content was measured gravimetrically by igniting<br />
samples in a muffle furnace at 500 o C. The Fibretest<br />
50<br />
system was used to analyse fibre content by<br />
treatment with neutral detergent (NDF), fibre content<br />
by treatment with acid detergent (ADF), sulphuric<br />
lignin content (ADL), according to the procedure of<br />
Van Soest (1963) and the photometrical method for<br />
the determination of total phosphorus. The analyses<br />
performed allowed the calculation of parameters for<br />
assessing the quality of the feed, such as the total<br />
digestible nutrients (TDN), net energy of lactation<br />
(NEL) and relative nutritional value (RFV). Calculation<br />
of these parameters was performed with the following<br />
formulas (A Nutritional Guide, 1990).<br />
TDN = 82.38 – (0.7515 × %ADF)<br />
RFV = (DDM×DMI)/1.29<br />
DDM = 88.9 – (0.779 × %ADF)<br />
DMI = 120/%NDF<br />
NEL: Mcal/lb = (TDN % x 0.01114) – 0.054<br />
Statistical analyses were performed applying the<br />
Least Significant Difference (LSD) test and principal<br />
component analysis using Statistica 8.<br />

RESULTS AND DISCUSSION<br />
Data characterizing forage quality in<br />
accordance with fertilization variant are given in<br />
Table 2. In the first experience (organic<br />
fertilization), the content in crude protein of the<br />
forages obtained from Nardus stricta L. permanent<br />
grassland increased from 6.39% at unfertilized<br />

t ha -1 manure at every two years, 12.80% for<br />
variant where was applied 40 t ha -1 manure at<br />
every two years and 13.14% for variant where was<br />
applied 50 t ha -1 at every two years. In the second<br />
experience (mineral fertilization), crude protein<br />
increased from the 6.48% at unfertilized variant to<br />
14.08% at N100P100 + N100P100 variant. The<br />
concentration of crude protein significantly<br />
increase with intensity of fertilization, in<br />
accordance with studies from the literature<br />
(Butkuvienė and Butkutė, 2007; Kirkham et a.<br />
2008; Avarvarei and Chelariu, 2011; Vintu et al.<br />
2011). The highest content of crude protein was<br />

manure every two years (Table 2). Neutral<br />

detergent fibre and acid detergent fibre content<br />
also affect the quality of grassland and its effect on<br />
animal nutrition.<br />
These parameters could be also used in<br />
prediction equations for nutritive value calculation<br />
(Jarrige, 1989), because cell-wall components –<br />
cellulose, hemicellulose and lignin are fully<br />
separated (Štýbnarová et al. 2012). The average<br />
content of NDF decreased significantly from 74.71<br />
% for unfertilized variant to an average of 50.08 –<br />
60.20 %, depending on fertilization for experience<br />
where was applied manure. The low content of<br />
NDF was obtained at variants where was applied<br />
40 t ha-1 manure every year (50.08%), followed by<br />
variant where was applied 50 t ha -1 . For experience<br />
with mineral fertilization the lowest value for NDF<br />
content was obtain for N200P200 (51,92%), followed<br />
by N100P100 + N100P100 (54,18) and N100P100 + N40P40<br />
(55.28%) variants. NDF is the most accurate<br />
characteristic of the total fibre content and it<br />
closely correlates with dry matter intake and<br />
rumination activity. The feed intake by ruminants<br />
decreases with extensive way of grassland<br />
management as the consequence of the high
concentration of NDF (Štýbnarová et al. 2012). For<br />
both experiments, organic fertilization and mineral<br />
fertilization the NDF contents are in comparable<br />
levels. Another measure of fibre is acid detergent<br />
fiber (ADF), a subset of NDF. cid detergent fibre<br />
contains the poorly digestible cell wall<br />
components, namely, cellulose, lignin, and other<br />
very resistant substances. Due to its nature, ADF is<br />
often used to predict energy content of feeds. ADF<br />
is a good indicator of feed quality; higher values<br />
within a feed suggest lower-quality feed.<br />
A goal would be to have < 35% ADF in<br />
either legume or grass forages The average of ADF<br />

Also, forages obtained from variants where<br />

Lignin is a polymer formed from monolignols<br />

considered an anti-quality component in forages<br />

Water, protein and energy are the nutritive<br />
elements that are required by the grazing animals<br />
in higher quantities for proper growth and<br />
production (Mountousisa et al. 2011). Often it has<br />
been suggested that the quality of feeds depends<br />
primarily on the energy content of them and<br />
particularly the component of metabolizable<br />
energy (Mlay et al. 2006). Thus, the influence of<br />
organic inputs and mineral fertilizants on the<br />
energy content of feed produced from a permanent<br />
grassland of Nardus stricta L. can be observed<br />
from the calculated quality parameters for the<br />
produced forages (table 3). The Relative Feed<br />
Value index estimates digestible dry matter (DDM)<br />
of the forages from ADF, and calculates the DM<br />
intake potential (as a percent of body weight, BW)<br />
from NDF. The index is then calculated as DDM<br />
multiplied by dry matter intake (DMI as a % of<br />
BW) and divided by 1.29. The total digestible<br />
nutrients (TDN), relative nutritive value (RVF) and<br />
net energy of lactation (NEL) increased<br />
significantly (p

In experience where was applied manure<br />
was a difference between variants where manure<br />
was applied every year (V2-20 t ha -1 , V3- 30 t ha -1 ,<br />
V4-40 t ha -1 , V5- 50 t ha -1 ) and variants where<br />
manure was applied at every two years (V6-20 t ha -<br />
1 , V7- 30 t ha -1 , V8-40 t ha -1 , V9- 50 t ha -1 ). In the<br />
experience where was applied mineral fertilization<br />
significant difference was between V6 variant<br />
(N100P100 + N100P100) and the other variants with<br />
different dose of chemical fertilization.<br />
CONCLUSION<br />
While on permanent grassland of Dorna<br />
Depression have been conducted numerous studies<br />
to increase their productivity, the studies on<br />
nutritive value of these forages are rather few and<br />
incomplete.<br />
The fertilization of Nardus stricta L.<br />
grasslands with organic and mineral fertilizers<br />
significantly improves its quality by increasing CP,<br />
total phosphorous content and by decreasing NDF,<br />
ADF and ADL levels. No significant differences<br />
between the use of organic and mineral<br />
fertilization were observed. This sustain the use of<br />
organic fertilizers, considering that currently<br />
agricultural practices recommend reducing the use<br />
of chemical fertilizers and promote other sources<br />
of fertilizer. The most advantageous variant of<br />
organic fertilization is V4 (40 Mg ha -1 every year).<br />
Relative feed value continues to be widely<br />
used as an index to assess quality, compare forage<br />
varieties, and forages price. However, differences<br />
in the digestibility of the fibre fraction can result in<br />
a difference in animal performance when forages<br />
with a similar RFV index are fed. The results for<br />
the relative nutritional value indicate average<br />
quality forages produced on the fertilized variants.<br />

In a bifactorial experience, during March-October 2010, at the Research Station Ezăreni from Iasi, we studied alfalfa in<br />
the first year of vegetation, analizing the effect of seed inoculation with symbiotic bacteria Rhizobium meliloti Dangeard<br />
and the effect of fertilization on the dry matter (DM) yield, the amount of crude protein per hectare, the leaves/stems<br />
ratio and the forage quality indicators (CP - crude protein content, NDF - neutral detergent fiber content, ADF - acid<br />
detergent fiber content and RFV - relative feed value). The results showed that under experimental conditions, the<br />
interaction of two factors led to DM yields ranging from 5.04 to 7.75 t·ha -1 and a quantity of crude protein of 1121-1539<br />
kg·ha -1 . CP content in leaves ranged from 24.04 to 30.29% and 10.51 to 19.80% between the strains, the leaves/stems<br />
ratio having the biggest influence on CP content of the whole plant. Analyzing the data, we observed that seed<br />
inoculation had an insignificant influence on the forage quality indicators. Fertilization positively influenced DM yield<br />
and amount of CP produced and had a negative impact on the leaves/stems ratio, plant content in CP, NDF, ADF and<br />
RFV.<br />
Key words: alfalfa, inoculation, fertilizer, productivity, quality<br />
Alfalfa (Medicago sativa L.) is one of the<br />
most valuable forage due to high production of<br />
green mass or hay and high quality forage.<br />
Lucerne has a high quality potential and<br />
ability to control factors can affect the quality and<br />
will improve production quality. Factors affecting<br />
quality are represented by soil fertility, cultivar, the<br />
presence of other species in culture, the use of<br />
pesticides, climatic conditions, harvesting (season,<br />
time of day and stage of development at harvest)<br />
and the method of preservation (Lloveras J. et al.,<br />
2004; Stancheva I. et al., 2008; Dragomir Carmen<br />
and Moisuc A., 2007).<br />
Evaluating the amount of crude protein<br />
produced per unit area, alfalfa can not be surpassed<br />
by any other forage crop in specific agroecological<br />
conditions of our country.<br />
Inoculation of seeds and providing the<br />
necessary nutrients through fertilization (mineral<br />
or organic) are two important technological links<br />
to improve productivity and quality of alfalfa<br />
(Oliveira W. S. et al., 2004; Berg W. K. et al.,<br />
2009; Dragomir N. and colab., 2010).<br />
MATERIAL AND METHODS<br />
The research was conducted during March-<br />
June 2010, on the Ezăreni farm (47°05'-47°10' North<br />
latitude and 27°28'-27°33' East longitude), farm<br />
belonging to the University of Agricultural Sciences<br />
and Veterinary Medicine Iaşi. The soil from the region<br />
is a cambic chernozem characterized by the indicators<br />
presented in table 1.<br />
Physico-chemical characteristics of soil that was placed experience<br />

bifactorial, with a design type 2x4, arranged in<br />
subdivided plots in three replications, which have a 10<br />
m 2 harvesting area (2m x 5m). The factors were as<br />
follows: A-seed inoculation with two graduations (a 1uninoculated<br />
and a 2-inoculated) and B-fertilization with<br />
four graduations (b 1-unfertilized, b 2-N 50P 50, b 3-N 75P 50<br />
and b 4-30 t·ha -1 manure).<br />
Yield production was determined by weighing<br />
the yield harvested from an area of 10 m -2 then<br />
reported per hectare.<br />
Dry matter was determined by treating samples<br />
at 105°C for 3 hours.<br />
The leaves/stems ratio was determined by<br />
separating the stem, leaflets, buds and flowers by the<br />
stem, weighing them separately and report their<br />
amount to the amount of strain (leaves/stems ratio).<br />
Nitrogen content was determined by Kjeldahl<br />
method, and NDF and ADF content were determined<br />
by Van Soest method.<br />
The amount of CP per hectare was calculated<br />
based on DM production per hectare and its content<br />
in the CP.<br />
RFV was calculated using the formula<br />
(Sheaffer C.C. et al., 1995; Boman R. L., 2010):<br />

Depending on the content CP, NDF, ADF and<br />
RFV, alfalfa hay can be classified into six quality<br />
classes (table 2), used by many authors (Mirzaei-<br />
Aghsaghali A. et al., 2007; Kiraz A.B., 2011; Redfearn<br />
D. and Zhang H., 2011).<br />
The biological material used was represented<br />
by Sandra alfalfa variety (F 660-94) registered in<br />
2003 to I.N.C.D.A. Fundulea. (Schitea Maria and<br />

Figure 2 Cycle of vegetation influence on the leaves/stems ratio<br />
The leaves/stems ratio varied depending on<br />
the number of cut. Thus, at the first cut the average<br />
percentage of leaves was approximately equal to<br />
that of strains, to the second cut leaves were 10%<br />
less than the stems, and at the third cut the leaf<br />

percentage was 27% higher than that of strains.<br />
The results confirm the research of other authors in<br />
similar experimental conditions (Bender A. and<br />
Tamm S., 2010; Stanćev Vidica et al., 2010).<br />
The leaves/stems ratio is an important
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
quality indicator, because of this depends quality<br />
of hay obtained. Percentage of leaves is desirable<br />
to be as high as possible, because in the leaves are<br />
found a crude protein content at least twice then in<br />
the strains, as shown by many authors (Popovic S.<br />
et al., 2001; Petkova D. and Panayotova G., 2007).<br />
Following results were found, although<br />

lower in fertilized plots due to leaves/stems ratio,<br />
negatively affected by fertilization (table 5).<br />
Although plants CP content in the fertilized<br />
variants was lower, the amount of CP was higher,<br />
statistically assured, due to higher yields obtained<br />
from these plots (table 6, figure 3).<br />

By analyzing the influence of inoculation<br />
and fertilization on alfalfa fiber content and<br />
relative feed value, it appears that inoculation had<br />
little influence on these indicators of quality feed.<br />
The results confirm the research of other authors<br />
who have come to similar conclusions, in<br />
conditions close to those present study<br />
(Hristozkova M. et al., 2009; Stevoviš Vladeta et<br />
al., 2010).<br />
Organic fertilization showed a statistically<br />
positive effect on the content of plant leaves and<br />
stems in NDF and ADF. The same trend was<br />
manifested in the case of mineral fertilization<br />

Figure 3 Amount of crude protein (CP) distribution<br />
strains except the ADF content, where the<br />
influence was reduced at the first and third cut<br />
(table 7, 8).<br />
Relative feed value of alfalfa plants and<br />
leaves was negatively influenced and very<br />
significant to all of fertilization treatments (table<br />
9). These trends, in terms of quality alfalfa under<br />
the influence of organic and mineral fertilization,<br />
confirming the results of research by other authors<br />
(Showalter J., 2000; Ketterings Q.M. et al., 2008).<br />
The forage obtained from the first and third can be<br />
classified as prime class (0), while the forage from<br />
the second cut can be classified as class 2.

CONCLUSIONS<br />
The first year alfalfa, inoculation resulted in<br />
no significant differences in productivity and<br />
quality of alfalfa, because the farm Ezăreni<br />
conditions (soil containing calcium by 3 ‰)<br />
Rhizobium meliloti Dangeard symbiotic bacteria<br />
has a sufficient presence in the soil.<br />
Research has shown that the leaves/stems<br />
ratio was different, depending on the experimental<br />
plot analyzed and the number of cut. At each of the<br />
three cuts, the leaves/stems ratio was better<br />
(meaning a higher percentage of leaves), for the<br />
unfertilized and organically fertilized plots<br />
Following results were found, although<br />
fertilization positively influenced the content of the<br />
leaves and stems in CP, CP content in plants was<br />
lower in fertilized variants, do to leaves/stems<br />
ratio, negatively affected by fertilization. Although<br />
plants CP content in the fertilized variants was<br />
lower, the amount of CP was higher due to higher<br />
yields obtained from these plots.<br />
Fertilization showed a statistically positive<br />
effect on the content of plant leaves and stems in<br />
NDF and ADF (lower values of these indicators).
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Relative feed value of alfalfa plants and leaves was<br />
influenced distinctive significantly and very<br />
significantly in all of fertilization plots.<br />
The forage obtained from the first and third<br />
can be classified as prime class (0), while the<br />
forage from the second cut can be classified as<br />
class 2.<br />

Biological nitrogen fixation is one of the most important biochemical reaction for life on earth. This paper presents the<br />
influence of the simple mixtures of perennial grasses and legumes and of the fertilization on dry matter production,<br />
quantity of nitrogen biological fixed. In this respect, we have experienced three mixtures consisting of Onobrychis<br />
viciifolia with Bromus inermis in different proportions, which were applied to three types of mineral, organic and<br />
vinassa fertilizer. The results obtained showed that under experimental conditions, total dry matter yields ranged from<br />
6.43-9.99 t ha -1 , the highest production was obtained from version A3b2, plant total nitrogen content (Nt) ranged from<br />
3.09 - 3.47%, total nitrogen the specific consumption (CSTN) of culture Onobrychis viciifolia (Scop.) ranged from<br />
43.65 to 47.31 kg t -1 DM, intake of specific nitrogen-fixing microorganisms (ASNF) ranged between 55.99 – 76.00 kg<br />
ha -1 and nitrogen remaining in the soil (NRS) ranged from 10.75 to 15.74 kg ha -1 .<br />
Key words: grasses, legumes, fertilization, nitrogen symbiotic<br />
Concerns for increased agricultural<br />
production, while switching to organic farming and<br />
reduction of fertilizer produced by industry, is one<br />
of the major problems of contemporary agriculture.<br />
Temporary meadows are the most effective<br />
sources of fodder for livestock farms. Fertilization<br />
is one of the main measures to increase production<br />
on these pastures, so that by cultivating legumes in<br />
mixtures decreases the amount of fertilizers used<br />
on lawns to achieve high yields. Organic<br />
fertilization and rational use of fertilizers can<br />
produce substantial increases of the production and<br />
biodiversity and fodder quality improvement<br />
(Vintu et al. 2008).<br />
Research aimed at studying and<br />
intensification of the fixation of atmospheric<br />
nitrogen by bacteria living in symbiosis with<br />
leguminous plants are of great importance<br />
(Hardarson et al. 1993).<br />
The estimation of nitrogen fixed to<br />
permanent and temporary grasslands differs from<br />
one country to another, from one pasture to another<br />
and depending on the floristic composition of the<br />
pasture (Carlson et al. 2003, Danell Huss et al.<br />
2007, Hansen et. al. 2002).<br />
Biological N2 fixation is regarded as a<br />
renewable resource for sustainable agriculture as it<br />
helps to reduce fertilizer N requirements and thus<br />
increases economic returns to producers<br />
(Hardarson et al. 2003; Jensen et al. 2003; Russelle<br />
et al. 2004; Walley et al. 2007). The substitution of<br />
forage legumes for inorganic-N fertilizer will save<br />
non-renewable resources required to manufacture<br />
and distribute fertilizer, provide deep-rooting<br />
systems and permanency of cover to improve soil<br />
structure, and hence reduce erosion, and limit the<br />
development of salinity in Mediterranean areas ,<br />
and clean up soils suffering from excessive<br />
fertilization (Rochon et al., 2004).<br />
The aim of this work was to follow mixing<br />
and fertilization influence on the amount of<br />
symbiotically fixed nitrogen, determined by<br />
indirect method, by species Onobrychis viciifolia<br />
Scop. is part of neophyte species commonly found<br />
in Moldavia, being a vegetable appreciated by<br />
large productions that are obtained (Sirbu, 2012).<br />
Organic and mineral fertilizers<br />
administration on the meadows, induce major<br />
changes on made productions (Pacurar et al. 2012,<br />
Vintu et al. 2011).<br />
Application of nitrogen fertilizer is indicated<br />
only in the establishment of vegetable crops in<br />
small doses to meet expectations of plants with<br />
symbiotic nodes that are not formed yet. High<br />
doses of nitrogen applied later are not effective<br />
because they reduce the activity and increase<br />
symbiotic nodules of production costs, while yields<br />
and quality remain the same (Oliveira et al., 2004).

MATERIALS AND METHODS<br />
The research was conducted in Ezăreni Farm<br />
(47°05' - 47°10' north latitude and 27°28' - 27°33'<br />
longitude east) belonging to the Didactic Station of<br />
the University of Agricultural Sciences and Veterinary<br />
Medicine, during 2008-2010. Soil that the experiment<br />
was installed is a molded cambic with pH 6.7-6.8,<br />
with a humus content between 2.73-2.93%, 21-25<br />
ppm PAL, KAL and 226-232 ppm calcium content of<br />
112-139 ppm. Factors studied were: Factor A mixture<br />
of 3 graduations: A1-70% Onobrychis viciifolia + 30%<br />
Bromus inermis, A2- 50% Onobrychis viciifolia + 50%<br />
Bromus inermis, A3- 20 % Onobrychis viciifolia - 80%<br />
Bromus inermis.<br />
Factor B - fertilization with 4 graduations: blank<br />
B1, B2-N100P100 kg / ha, B3-5 t / ha vinassa, B4-30<br />
t / ha manure.<br />
Vinassa, manure and phosphorus fertilizer<br />
were applied in the fall of 2005, and nitrogen<br />
fertilizers were applied before sowing spring. Vinassa<br />
is a by-product obtained during production of bakery<br />
yeast. Vinassa has a complex chemical composition,<br />
being rich in total nitrogen (3.0 to 3.2%), very rich in<br />
potassium (5-7%) and low in phosphorus (0.3 to<br />
0.5%). Chemical composition of manure was the<br />
following 5 kg N, 3 kg P 2O 5 and 7 kg K 2O per ton of<br />
garbage.<br />
Mass production was determined by weighing<br />
green harvested area of 10 m2 and then reported to<br />
the hectare. Dry matter was determined by drying in<br />
an oven at 105 º C for 3 h (ISO 6496). Nitrogen<br />
content of plants was determined by the Kjeldahl<br />
method. Humus content in soil was determined by<br />
Walkley-Black method in changing Doughnut, wet<br />
oxidation method and dosage titration. Statistical<br />
calculation was performed by analysis of variance.<br />
That way, were determined the total nitrogen<br />
the specific consumption of culture (CSTN), the<br />
specific contribution of nitrogen-fixing microorganisms<br />
(ASNF) and residual nitrogen in the soil (NRS) with<br />

The biological material used was the variety of<br />
Onobrychis viciifolia Scop.- SPLENDID and variety of<br />
Bromus inermis L. - DOINA.<br />
RESULTS AND DISCUSSION<br />
The organic and mineral fertilizers cause<br />
significant changes in the structure of vegetation<br />
cover and production of temporary grassland<br />
(Nyfeler et al. 2008, Smit et al. 2008). Productions<br />
were similar to those obtained by Dragomir C.,<br />
2009 in similar conditions of culture. In all three<br />
types of mixtures studied were observed increases<br />
in dry matter production in fertilized compared to<br />
control variant versions. Thus, the mixture of 20%<br />
Onobrychis viciifolia Scop., production increased<br />
from 6.43 t ha -1 DM in variant without fertilization,<br />
the fertilization DM 7.42 to 5 t ha -1 vinassa and<br />
7.64 t ha -1 DM in version N100P100 kg ha -1 .<br />
While the mixture consisting of 50 %<br />
Onobrychis viciifolia Scop. and 50 % Bromus<br />
inermis L. dry matter production increased from<br />
8.67 t ha -1 DM in variant without fertilization, to<br />
8.72 t ha -1 DM to 30 t ha -1 manure, it went up to<br />
9.35 t ha -1 DM at fertilization with N100P100 kg<br />
ha -1 (figure 1). After the mixture x fertilization<br />
interaction, the highest productions were obtained<br />
at the mixture of 70 % Onobrychis viciifolia Scop.<br />
the variant fertilized with N100P100 kg ha -1 .<br />
The study analyzing the influence on total<br />
nitrogen content of plants shows that this index<br />
was positively influenced by the application of<br />
fertilizers (figure 2). Compared with variants<br />
without fertilization increased the percentage of<br />
nitrogen fertilization N100P100 kg ha -1 from 3.27<br />
% to 20 % Onobrychis viciifolia Scop. mixture to<br />
3.47 % at mixture with 70 % Onobrychis viciifolia<br />
Scop.. Fertilization with 5 t ha -1 vinassa total<br />
nitrogen content in plants was between 3.20 % to<br />
20 % Onobrychis viciifolia Scop. mixture and 3.46<br />
% to 70 % Onobrychis viciifolia Scop. mixture<br />
(Fig. 2).<br />
Specific contribution of nitrogen-fixing<br />
microorganisms (ASNF) ranged from 65.4 - 75.97<br />
kg ha -1 , the variant without fertilization (figure 3).<br />
After the mixture x fertilization interaction highest<br />
values were obtained from the mixture with 70%<br />
Onobrychis viciifolia Scop. on variant b2, namely<br />
89.46 kg ha -1 . Vinassa fertilization and manure<br />
resulted in getting close to those amounts from<br />
fertilization N100P100 kg ha -1 .

Application of fertilizers (organic or<br />
mineral) significantly reduced symbiotic activity<br />
which fixes atmospheric nitrogen, most of the<br />
plants using non symbiotic nitrogen so the<br />
efficiency of nodes is reduced. Total specific<br />
nitrogen consumption in leguminous culture<br />
(CSTN), the first year of vegetation, ranged from<br />
43.65 to 47.31 kg t -1 DM (Fig. 4.). Application of<br />
organic fertilizers and caused a greater<br />
consumption of nitrogen to produce a kg of dry<br />
matter, to version control (unfertilized). At the
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
doses of fertilizer applied, CSTN differences are<br />
significant (figure 4).<br />
Quantities of nitrogen remaining in the soil<br />
after the first year of vegetation, ranged from 10.75<br />
64<br />
- 15.74 kg ha -1 . The fertilized variants of residual<br />
nitrogen in the soil (NRS) were lower compared to<br />
the variant without fertilization in the first mixture<br />
(figure 5.).<br />

Figure 5 The influence of mixture x fertilization interaction on residual nitrogen in the soil (NRS),<br />
in first year of vegetation<br />
At A2 and A3 mixtures, there were small<br />
differences between the amounts of nitrogen left in<br />
vinassa and manure fertilized variants of soil<br />
compared to b1. On the b2 variant the values<br />
obtained were lower compared to all mixtures<br />
studied in the variant without fertilization. At the<br />
amount of organic nitrogen fertilizer remaining in<br />
the soil, determined by calculation, is added the<br />
amount of nitrogen in manure because, in practice,<br />
the coefficient of nitrogen in manure is, in the<br />
application year, between 30-50%.<br />
CONCLUSIONS<br />
Analyzing the influence of mixture x<br />
fertilization interaction, the highest productions<br />
were obtained from the mixture with 70%<br />
Onobrychis viciifolia Scop. on variant with<br />
N100P100 kg ha -1 . Production increases were<br />
recorded for fertilization with manure and vinassa<br />
regardless of the percentage of legumes in the<br />
mixture. Following research observed that<br />
fertilization had a positive effect on the total<br />
nitrogen content of plants and specific contribution<br />
of nitrogen-fixing microorganisms (ASNF),<br />
specific consumption of culture total nitrogen<br />
(CSTN) and residual nitrogen in the soil (NRS).<br />
Symbiotically fixed nitrogen ranged from 50.19 to<br />
76.3 kg ha -1 and nitrogen remaining in the soil after<br />
the first year of vegetation ranged from 10.75 -<br />
15.74 kg ha -1 .<br />

This study is intended to review the geomorphological basin Bahluiet for determining the height and slope exposure.<br />
This stage is important in terms of erosion and methods to combat them. Studies on problems of soil erosion have<br />
become current because reduction of agricultural areas and of the phenomenon in declining of productivity. Among the<br />
factors that influence the erosion we can mention landscape, climatic conditions, soil type, vegetation and human<br />
activity. The landscape has a special role because it influences water movement on slopes, water being the active<br />
separation, dispersion and transport of soil particles factor. Within each river basin, soil erosion varies depending on<br />
slope characteristics (shape, angle, length, exhibition, area) being lower or stronger. Based on detailed study of the<br />
natural environment and categories of usage, is established the method for reduction of soil erosion. In this study, we<br />
determine the maps for the slope categories, the share of the slope exhibitions and also the structure of the categories of<br />
usage in the considered river basins perimeter.<br />
Key words: land use, degradation, GIS, erosion control technique<br />
Bahlueţ River Basin is located in the<br />
Moldavian Plateau, in an area of transition between<br />
Suceava Plateau to the west, Central Moldavian<br />
Plateau to the south and the Moldavian Hilly Plain<br />
to north and east. From the total area of Bahluiet<br />
basin, about 569.83 km 2 , over 15% are represented<br />
by landslides and slope geomorphological<br />
processes. In this region, the natural conditions and<br />
human activities have resulted in increased<br />
erosion.<br />
The landscape, by inclination, length, area<br />
and slope form, largely conditions the surface<br />
runoff and soil water infiltration, triggering and<br />
maintaining erosion. When to determine the<br />
cultures’ structure on slopes with different<br />
exhibitions, one should be aware that the southern<br />
exhibition slopes receive more heat and light as the<br />
northern ones. Baloi et al. (1986) estimated that the<br />
southern and western slopes are 30-40% more<br />
eroded than those with northern exposition. Guş P.<br />
found that the southern slopes are heated by 3-5 °C<br />
higher than those with northern exposition. Soil<br />
erosion is characterized by the release of the land<br />
surface of soil and rock particles, their carriage<br />
from the place of origin and their placement<br />
elsewhere. This is a natural process comprising<br />
three phases, which are made by two main agents:<br />
water and air in motion, whose sources are solar<br />
radiation energy and gravity.<br />

Accepting that erosion is inevitable<br />
considering soil loss tolerance level of 2-5 t / ha /<br />
year, corresponding to an annual rate of natural<br />
soil recovery, technologies to be applied must<br />
control these limits (Ionescu, 1977; Motoc et al.<br />
1979, 1982, 1999; Savu 2002; Bucur 2006, 2007).<br />
Compared with the diversity of geomorphological<br />
and pedo-climatic factors in Romania, research on<br />
soil erosion processes were performed in very few<br />
areas.<br />
Research on potential erosion, which is<br />
conditioned by geomorphological and pedoclimatic<br />
factors, showed that the NE region average soil<br />
erosion losses are 18.3 t ha -1 year -1 , values<br />
corresponding to moderate erosion risk (Ionita<br />
2000, Bucur and Ailincai 2006). Research on<br />
effective erosion, which were based on direct<br />
measurements and complex analysis, which<br />
integrated the effect of vegetation and antierosion<br />
works have shown that effective erosion<br />
throughout the NE region has an average of 4.6 t<br />
ha -1 year -1 .<br />
Taken together, the consequences of erosion<br />
and sliding of the slopes of the Plain of Moldavia<br />
on the environment, nature and human<br />
communities are real, very damaging to future<br />
generations so that scientific research and public<br />
awareness activities on ways to improve, protect<br />
and use degraded lands are extremely necessary.

MATERIAL AND METHOD<br />
This study was made for Bahluiet Basin which<br />
also includes Scobâlteni basin in which antierosion<br />
agrotechnics field is located, where the research was<br />
conducted.<br />
Using GIS techniques and orthorectified<br />
photos allows a diachronic analysis on very large<br />
surfaces. To acquisition of this images, have been<br />
used topographic maps 1:50.000 and implement<br />
methods of scanning-vectorization. The next step was<br />
to geo-referencing maps which mean determining<br />
geographical coordinates for a particular type of<br />
cartographic projection.<br />
A complex analysis in relation with erosional<br />
factors was made starting from the Digital Elevation<br />
Model and the thematic maps, realized with TNTmips<br />
software.<br />
Slope length was obtained using SAGA<br />
software (System for Automated Geoscientific<br />
Analyses), which allows multiple operations with<br />
raster files with great applicability in geomorphometry<br />
and hydrology.<br />
RESULTS AND DISCUSSIONS<br />
Geological, landscape, climate,<br />
hydrography, vegetation and especially<br />
anthropogenic intervention conditions, found<br />
throughout the Bahluiet basin led to the evolution<br />
of erosion on large areas. The soils are most<br />
affected by these processes, large amounts of<br />
material that comes mainly from the fertile surface<br />
horizon, being transported to the slopes.<br />
Surface erosion develops in all places where<br />
there is a small slope as that to permit a diffuse<br />
leakage of water. The decline of productivity<br />
produced by erosion leads to changing the soil<br />
characteristics such as soil fertility down.<br />
Simultaneously with experiments at standard plot<br />
level, research at slope and river basin level was<br />
made, obtaining valuable results.<br />
In terms of conditions that favor the surface<br />
erosion in the area, the arable land located on<br />
slopes greater than 5% are the most exposed<br />
surfaces (Motoc, 1983).<br />
As the factors of soil erosion control,<br />
rainfalls are the primary agent, especially the<br />
torrential rainfalls from May to June. Thus, both<br />
the rain water and snow melt are the active factors<br />
of soil erosion.<br />
Another factor causing and developing<br />
erosion is the landscape of the terrain, taking into<br />
account that its structure depends on the speed and<br />
the force of flowing water. Because the strongest<br />
erosion processes occur on slopes, it should be<br />
noted that the land slopes differ as slope, length,<br />
shape, exhibition and surface.<br />
68<br />
The microclimate with western slopes<br />
exhibition is characterized by a plus of heat during<br />
the day, snow depth smaller, lower humidity.<br />
As a result of stronger insolation and more<br />
intensive evapo-transpiration, soil water deficit is<br />
greater. These slopes are more exposed to cold<br />
winds, temperatures are higher therefore are more<br />
favorable for some crops. Microenvironment of<br />
low inclined plateaus is characterized by a strong<br />
sun exposure, large diurnal temperature variation,<br />
low humidity and winds with higher intensity.<br />
Depending on slope land, are established use<br />
categories, agro-technical methods and soil erosion<br />
control works.<br />
Erosion works to achieve its purpose, must<br />
be designed in complex on hydrographical basins<br />
together with a complex of works including:<br />
organization planning, agropedoameliorative<br />
works, arrangement works of slopes, agrotechnical<br />
works, planning and stabilization of the flux and<br />
land slipped.<br />
For the struggle against erosion is more<br />
efficient, there is still necessary a series of<br />
measures to complete the positive effect of the<br />
methods which are imposed. These measures<br />
include location and method of planting crops on<br />
sloping land. The main crop systems on sloping<br />
land are culture system strips, buffer strips culture<br />
system and culture system with agrotesase.<br />
Figure 1 Slope land categories from BH Bahluiet<br />
For the Bahluiet basin, the slope categories<br />
are presented in Fig. 1. In agricultural terms, the<br />
map of slope categories is very important taking<br />
into account that the suitability of land on low<br />
slopes, unchanged by the geomorphological<br />
processes, can lead to the establishment of<br />
effective methods in preventing soil erosion.<br />
In figure 1 can be observed that the largest<br />
area of land has slopes between 5-8%, while over<br />
18% slopes occupy small areas especially in the<br />
south of the basin. In the north of the basin studied,<br />
the slopes are calling 5%. Overall, the Bahluiet<br />
basin dominates the land with slope values ranging<br />
from 9-19%, thus showing that slopes create the<br />
dominant landscape of the area studied (Fig. 1).
Under these values, lands from the Bahluiet basin<br />
fall mostly in the typology of low / moderate<br />
slopes. However, even for such low angle slopes<br />
but with a predominantly agricultural use (with<br />
specific hill-valley plowing) surface erosion<br />
occurs, washing fertile horizon rich in humus,<br />
causing significant damage to agricultural<br />
production.<br />
For the considered territory, slopes are<br />
considered within a large range of values, from<br />
areas with less than 2% slope in meadow areas and<br />
up to 45% in cornices areas that border some the<br />
slopes at the top. Lowest values of the field<br />
gradients (45%<br />

in Bahluiet and Scobalteni catchment<br />
Depending on slope land, usage categories,<br />
agro-technical methods and soil erosion control<br />
works are established. Antierosion works, in order<br />
to achieve its purpose, must be designed in<br />
complex, on river basins, together with a set of<br />
works including: land organization, agropedoameliorative<br />
works, works relating to slopes,<br />
agrotechnical works, planning and stabilization of<br />
torrents and land sliding, etc. Antierosion works<br />
ensures soil protection and protects the whole area<br />
of the river basin when are designed, built and<br />
filled with appropriate agrotechnical works,<br />
primarily ameliorative crop rotation, fertilization<br />
systems and tillage. Some of these categories of<br />
works must be provided by the land beneficiaries<br />
but in large river basins, where soil antierosion<br />
works predominate, hydroameliorative specialized<br />
systems must operate.<br />
Extent of erosion is determined by the slopes<br />
exhibition. In figure 3, we present for<br />
exemplification the slopes exposition from<br />
Bahluiet basin.<br />

In figure 4, it is establish that in Scobalteni<br />
basin, sunny slopes (S and SW) have the largest<br />
share of orientation (35%), followed closely by the<br />
semisunny (SE V - 31%) and those semishaded (N,<br />
E - 29%). Shaded slopes (N, NE) have the lowest<br />
percentage (5%).<br />
If on low land slopes, up to 7-8% angle,<br />
lower erosion control can be achieved by methods<br />
which means agro soil tillage on the contour, crop<br />
rotation or fertilization, on lands with a slope of 8-<br />
12% is required the introduction of antierosional<br />
system of crop strips and with a slope of 12-20%, a<br />
grass strip culture system.<br />
CONCLUSIONS<br />
In Bahluiet basin, both components of the<br />
natural and the human, have maintained a steady<br />
erosion over time. Overall, in the Bahluiet basin<br />
dominate the lands with slope values ranging from<br />
9-19%. With increasing slope, the crops structure<br />
must increase the cultivation share of good and<br />
very good protection crops against erosion, so that<br />
losses of soil erosion does not exceed the tolerable<br />
limit. Based on morphometric analysis indicators it
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
can be seen that most of the Bahluiet basin<br />
landscape is of hilly type.<br />
By analyzing factors of erosion control in<br />
conjunction with land use method as benchmarks,<br />
it could be obtained a number of indices to express<br />
the real degradation of soils in the current context<br />
of land use. Thus, a system of sustainable<br />
agriculture that is conspicuous by the presence of<br />
an extraordinarily large number of small farms,<br />
within a highly fragmented landscape,<br />
characterized by the dominant presence of slopes<br />
with high instability, expresses a general trend of<br />
soil degradation in this basin.<br />

Crop structure is a component of the agricultural production. Intensive production structure can be characterized by a<br />
higher share of production in gross added value (example: 62.0% - in Germany, 50.9% - in France, etc.) or extensive,<br />
practiced, usually in cereal or small farms. The areas share of main crops in the structure of arable land has changed<br />
considerably, so that, at the country level, the share exceeded 64% of cereal grains, having a negative effect on the<br />
achievement of rational rotations and maximum weight in rotation, in many cases by setting up monoculture, with<br />
consequences for decreasing the productive power of soil and yields. Therefore, to ensure economic efficiency in crop<br />
production, crop structure optimization is necessary, to combine food safety, increasing the size of farms and their<br />
profitability. The authors have proposed using a case study to demonstrate that through optimal crop structure, among<br />
other technological factors, of advanced management and marketing, can provide a high level of overall economic<br />
efficiency, especially in vegetal production.<br />
Key words: crop structure, optimization, efficiency<br />
Component of production, crop structure is<br />
influenced by many factors, including soil which<br />
plays a key role (Chiran A., 1998).<br />
Also, in the choice of crops and cultivated<br />
areas, a special role have the economic,<br />
organizational, biological and social factors,<br />
covering: the requirements of national economy,<br />
technical and material resources of the unit, labor<br />
resources, distance from resources supply centers<br />
and products recovery, farm size, crop self<br />
affordability cultures, economic efficiency (Chiran<br />
A., 2001, 2002, Crăcăleanu Maria, 1994,<br />
Davidovici I., 1993).<br />
Economic efficiency of each culture should<br />
be a basic factor, its level being considered by a<br />
technical-economic indicators system, which may<br />
contribute to the development of optimal structural<br />
variants of crops (Dona I., 2000).<br />
Optimizing crop structure is a<br />
consequence of the need for plant production<br />
scheduling in territorial profile, which means a<br />
judicious zoning and rational combination of<br />
cultures.<br />
MATERIAL AND METHOD<br />
The case study was conducted at S.C.<br />

S.C. AGRICOLA BEESARSEN S.R.L.<br />
DOCHIA, is one of the most representative<br />
companies of Neamt county agriculture, being<br />
among the top three companies producing cereals<br />
and technical plants.<br />
Main object of unit activity is agricultural<br />
production, represented by culture and storage of<br />
grain and other agricultural products, livestock, and<br />
other secondary activities and trade.<br />
To highlight the influence of optimizing the<br />
crops structure in arable land on crop production<br />
economic efficiency, the analysis focused on cereals<br />
and technical plants.<br />
For this purpose, the authors based on a<br />
system of technical and economic indicators, which<br />
highlight the following: supply of grain and oilseed<br />
production, production per hectare, cost of<br />
production, unit cost, selling price, commodity<br />
production, income and turnover, market share, profit,<br />
profit rate, etc.<br />
RESULTS AND DISCUSSIONS<br />
The crop structure has changed<br />
permanently, so that now, cereals and technical<br />
plants are operating in three vegetable farms with<br />
1270 hectares of arable land.<br />
In addition to cereals (wheat, barley, rye,<br />
triticale, oats and corn) that occupy the largest<br />
share in crop structure, in recent years has given
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
special attention to technical crops cultivation<br />
(rapeseed, sunflower, sugar beet).<br />
In 2011, the turnover showed an upward<br />
trend, both in total and by product (table 1).<br />
Cereals turnover had a positive<br />
development, so that compared to 2010, the growth<br />
72<br />
was 43.8%. Furthermore, for wheat, was registered<br />
the highest turnover and at S.C. AGRICOLA<br />
BEESARSEN S.R.L. DOCHIA, in 2011, the<br />
minimum values were registered in soybeans and<br />
corn.<br />

which indicates the average market share held by<br />
the first 4, 8, 12 companies;<br />
- market concentration index, which is<br />
used as a possible indicator of market power or<br />

Cost analysis is a technique for enterprise<br />
performance evaluation that helps at reflect the<br />
usage of material and human potential of the<br />
company and identify cost reduction of existing<br />
stocks in the company.<br />
Structural analysis of costs provides an<br />
opportunity now to act on that category of<br />
spending that has an undue share (Chiran A, 2004;<br />
Olaru Adriana, 1994; Pânzaru L., 1994).<br />
S.C. Agricola Beesarsen S.R.L. Dochia, as<br />
commercial enterprise, is different in terms of fee<br />
structures and different categories of expenditure<br />
share in total as follows:<br />
-materials costs 60%, 70% - goods cost;wage<br />
costs 20%;<br />
-distribution costs 15% - 5% overheads;financial<br />
costs 5%;<br />
-research and development expenses 5%.<br />
Total expenditure in 2011 had the following<br />
structure (Table 6).<br />
Profit analysis can provide information on<br />
absolute profitability of the company. To get the<br />
ability to produce profit, profit comparison is<br />
required with other sizes, especially sizes<br />
expressing broad effort to obtain profit, releases<br />
thus rates of return which, in terms of analysis,<br />
have a greater information capacity.<br />
Relative profitability is a ratio between the<br />
economic and financial obtained effects and efforts<br />
to achieve them.<br />
In the economic and financial analysis of<br />
company results, the rates of return allow making<br />
comparisons between groups of firms in relation to<br />
developed standards.<br />
Table 5<br />
The invested capital efficiency of all the<br />
material, financial resources involved in enterprise<br />
activity, are presented by economic rate of<br />
return.<br />
The economic rate of return must be<br />
assessed according with the inflation rate. An<br />
economic rate of return higher than inflation will<br />
preserve "economic substance" of the company<br />
and even economic renewal and growth of its<br />
assets, in a short period.<br />
Economic rate of return should exceed the<br />
inflation rate to be possible to pay the capital<br />
invested at a minimum average rate of the<br />
economy and the level of economic and financial<br />
risk assumed by those who invested.<br />
Operating results are determined as the<br />
difference between operating revenues and<br />
expenses, for a calendar year.<br />
The net result of the exercise is the profit<br />
to be distributed for dividends, the part from the<br />
taxable profit of the trader and entrepreneur returns<br />
(shareholder or member).<br />
The final results obtained by SC Agricola<br />
Beesarsen SRL Dochia were positive, but the size<br />
indicators was influenced by massive investments<br />
achieved for modernization of production<br />
capacities (tractors, harvesters, seeders, plows)<br />
performance with which the unit will manufacture<br />
products at lower cost and can be competitive on<br />
both domestic and the European market.

CONCLUSSIONS<br />
S.C. Agricola Beesarsen S.R.L., Dochia,<br />
Neamț County realized during 2005 - 2008,<br />
massive investments in production technology and<br />
improvement of land quality to achieve high yields<br />
per hectare and reduce the cost per tonne of<br />
product.<br />
Average yield per hectare has increased by<br />
17.65% at rapeseed and at sunflowers by about<br />
25%.<br />
As a result of optimizing the structure of<br />
crops, plant products were obtained at lower cost<br />
and by the optimal storage and recovery period, it<br />
can be realized additional revenue and higher<br />
profits.<br />
The increased revenue and profitability of<br />
vegetal products is explained by the high<br />
percentage of quality seeds obtained. Thus, the<br />
return rate was 214.6% for rapeseed, 123.2% for<br />
sunflower, etc.<br />
To increase the efficiency of the company,<br />
the management team role is to develop and<br />
implement successful strategies which determine<br />
market opportunities and competitive advantage,<br />
based on control of marketing results, highlighting<br />
the risks, favorable circumstances, strengths and<br />
weaknesses of organization. By translating them<br />
into practice it must be createed such a system of<br />
relationships between business and environment to<br />
ensure its placement in the best possible position in<br />
dealing with competitors.<br />

In this paper we propose to make some observations on the useful and harmful entomofauna semnicere two lots and two<br />
lots of wheat seed corn. Observations were made in 2012. The culture of wheat seedlings, observations were made in<br />
spring varieties and drop, and two varieties of corn produced by a multinational. The research was took place and<br />
during 2012, especially Phases of growth 0 – (Sprouting - East) Phases of growth 0,5 - (two leaves fully formed) Phases<br />
of growth 1 - (four leaves fully formed). The study was conducted in order to track and have followed the main pests of<br />
this crop, it was made regular observations directly on the farm. In addition to direct observations on the farm, also<br />
harvesting samples and evidence using the beeing method and traps soil type Barber. Specify that in the stationary from<br />
the SC Astra Trifesti, Iasi County, samples collected was made from different seed lots in terms of cultivation<br />
technology.<br />

Wheat plant with great significance in terms<br />
of food. Wheat is grown in over 100 countries,<br />
feeding 35 to 40% of humanity. The main use is<br />
the bread and various products are made from<br />
flour.<br />
The predominant composition of wheat<br />
grain carbohydrates - 62-75% of the fresh grain,<br />
formed more than 90% of starch, dextrin and the<br />
remainder other simple carbohydrates.<br />
Carbohydrates are accumulated mainly in the<br />
endosperm.<br />
Wheat humpbacked beetle attack (Zabrus<br />
tenebrioides, Goeze), is very dangerous and<br />
should be avoided on land infested wheat location<br />
and also treat the seed before sowing. In extreme<br />
cases, while in autumn there is a strong attack<br />
humpbacked beetle larvae, we recommend<br />
treatment with insecticide chlorpyrifos (Dursban<br />
480 EC, 2.0 l / ha; Basudin EW 600, 2 l / ha), the<br />
warning of pest economic threshold (PED) is 5%<br />
of plants attacked<br />
Against grain bugs (Aelia spp spp<br />
Eurygaster) of treatment against the adults<br />
hibernate, the warning, a 7-PED exemplare/m2<br />
and only after more than 80% of the bugs left<br />
wintering areas (forest), usually in the second<br />
decade of April, when the temperature exceeds 10<br />
° C.<br />

Corn has a high production capacity by<br />
about 50% ri ¬ dictated to other cereals, has a<br />
high ecological plasticity, which allows a wide<br />
distribution area, giving high yields and relatively<br />
constant, less fluent deviations in ¬ climate, is an<br />
herb hoe, good run for most crops. (L.S. Muntean,<br />
2003)<br />
Losses in agricultural crops vary as follows:<br />
the grain varies between 27-36% of the pests to<br />
return between 8-15%. (Tălmaciu M., 2005).<br />
The purpose of these Researches, is to<br />
cause harmful entomofauna four seed lots, two<br />
corn and two of wheat, of SC Astra Trifesti, Iasi<br />
County.<br />
The main pests of these crops: corn leaf<br />
weevil (Tanymecus dilaticollis), beetles<br />
firecrackers (Agriotes spp), Owl crops (Scotia<br />
segetum Schiff), Sfredilitorul maize (Ostrinia<br />
nubilalis Hb), corn root worm (Diabrotica<br />
virgifera virgifera Le Conte), steppe beetle<br />
(anoxia villosa L), humpbacked beetle (Zabrus<br />
tenebrioides, Goeze), cereal bugs (Aelia spp spp<br />
Eurygaster (Tălmaciu M., 2005)<br />
MATERIALS AND METHODS<br />
Observations were made in 2012 in SC Astra<br />
Trifesti Ltd, which is the micro-area Bivolari<br />
Gathering material was ground with type<br />
Barber traps.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Traps were placed in four different seed lots,<br />
two wheat and two maize which we call Group I,<br />
Group II, Group III, group IV.<br />
This research is a continuation of research<br />
begun in 2011.<br />
RESULTS AND DISCUSSION<br />
The research was conducted in 2011 and<br />
2012. In all seed lots were made treatments Karate<br />

This paper shows the results obtained for dyeing protean fibers (wool) with carthamin, which is a natural pigment<br />
extracted from saffron flowers (Carthamus tinctorius L.). We aimed mainly for the optimisation of the dyeing process<br />
in terms of investigation of the quantity of natural pigment ingrained on wool fiber. The used method for this study was<br />
the multiple regression method which through data processing on computer has lead to the getting of a curve in space<br />
and in plan which allowed the establishment of optimal parametres for dyeing: pigment concentration, temperature of<br />
dyeing bath and duration of dyeing process.<br />
Key words: : dyeing natural, carthamin, multiple regression method, protean fibres<br />
Saffron, Carthamus tinctorius, L., is an<br />
annual plant, which is cultivated mainly for oil<br />
which is extracted from akenes (fruits), used in<br />
food industry because of high concentration of<br />
saturated fatty acids and especially of linoleic acid<br />
(vitamin F).<br />
Flowers of this plant are used to extract<br />
carthamin (a very durable red pigment, also called<br />
“Safflower Red”) and a yellow pigment<br />
(“Safflower Yellow”), which is supposed to be 2<br />
geometrical isomeres, quite unstable (“Safflomin<br />
A” and “Safflomin B”), of wide use in food,<br />
pharmaceutical, cosmetic and textile industries.<br />
In terms of chemistry these pigments belong<br />
to flavones class, and in terms of technology they<br />
have a structure close to that of dispersion<br />
pigments. In Colour Index we find the carthamin in<br />
position C.I. Natural Red 26-75140 (Colour Index,<br />
1982) (figure1).<br />
In terms of structure, the carthamin holds<br />
in its molecule 5 carbonyl groups (>C=O), which<br />
form the chromophores ( they are groups of atoms<br />
which colour the substance, groups “which bring<br />
colour”) and 13 hydroxyl groups (-OH) which play<br />
the role of auxochromes (they are groups of atoms<br />
which intensify the colour).<br />

The first informations about use of vegetal<br />
pigments date around 2650 B.C. In China. Since<br />
then and until now, man has been always interested<br />
in using these natural resources, close to him, for<br />
dyeing and decorating textile materials both for<br />
utilitarian interest and aesthetic reasons and also<br />
for killing boredom of daily life. (Jolin&Margaret<br />
Cannon, 1994,).<br />
Of all the protean natural fibers, wool –<br />
because of its complex physical-chemical<br />
composition- presents an exceptional elastic and<br />
tinctorial behaviour.<br />
Therefore through the presence of<br />
polypeptide bonds (-NHCHRCO-) and isopeptide<br />
bonds and disulfide bonds -bonds which are
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
created during the growth of fibre through the so<br />
called process of keratinisation -and also of ionic<br />
bonds ( type salt bonds) between lateral acyclic<br />
bonds (carboxylic) and basic (amic) which give an<br />
amphoteric character to wool fibers, make wool<br />
fibers a textile support with a superlative<br />
behaviour.<br />
MATERIAL AND METHOD<br />
For this study there have been used samples<br />
of sheep fur, of endemic production, with a length of<br />
wool yarn of 15 mm.<br />
We aimed mainly the optimisation of dyeing<br />
process in terms of investigating the quantity of<br />
natural pigment ingrained on wool fibre. For that we<br />
used as experimental instrument the mathematical<br />
modelling, using factorial programming in a central<br />
composite rotatable 2k program, considering the use<br />
of a mathematical model with three independent<br />
variables to be expressive and efficient because<br />
these have the quality of taking in account a<br />
reasonable number of technological parametres, with<br />
a higher degree of covering and conclusions can be<br />
applied with a higher degree of probability (Mihail,<br />
R.,1976; Gluck, A., 1971; Ciocoiu Mihai, et al., 2002).<br />

The general form of mathematical model with<br />

Coded and real values of independent variables<br />
As independent variables we chose dyeing<br />
duration, pigment concentration and temperature of<br />
dyeing bath, and as dependent variable we chose a<br />
quantity which reflects the two major aspects in the<br />
process development, respectively tinctorial<br />
characteristics and those regarding textile material<br />
integrity, namely the pigment quantity ingrained on<br />
wool fibre, Y.<br />
Through this method we aimed to obtain<br />
statistical mathematical models which can correlate<br />
the variation module of investigated coefficients with<br />
development parametres of tinctorial process, method<br />
which holds two consecutive directions of work: the<br />
programming of experiments and the analysis of<br />
experimental data.<br />
For this study we have taken the parametres<br />
presented in Table 1. which show the values of these<br />
in coded and real units.<br />

For the establishment of independent<br />
variables limits we chose a temperature interval<br />
between 39,4 °C and 70,6°C because in the<br />
scientific literature it is stated that at temperatures<br />
higher than 65-68 °C, the red pigment (carthamine)<br />
becomes unstable, the colour going for yellow.<br />
The determination of pigment quantity<br />
ingrained on wool fiber (from fur) has been realised<br />
with the help of a spectrophotometer<br />
SPECTROFLASH SF-300- Data Color through the<br />
measurement of K/S proportion ( function Kubelka-<br />
Munk which represents a relation between the<br />
optical properties of dyed textile materials and the<br />
concentration of pigment in material, respectively the<br />
concentration of pigment used for dyeing, using the<br />
optical properties of dyeing – light scattering and<br />
absorption – and luminance at the wave length<br />
where the absorption of light energy is maximised,<br />
λ max) (Pustianu, M., et al., 2002), at wave length of<br />
520 nm. For the difference of colour we used the<br />
relation DE*CIELAB.<br />

Data obtained from measurements is<br />
presented in column Y măs of experimental matrix<br />

After verifying the signification of multiple<br />
correlation coefficients, by applying the Fisher<br />
test, whose calculated value is F=30,742 and by<br />
elimination of inconsistent terms, by the smallest<br />
squares method, we obtained the following<br />
regression equation:<br />
Y =41,1856+3,7574x1+3,3548x2+7,8359x3 +1,1738x1x2<br />
+0,7938x1x3 +4,1113x2x3+0,7610x1 2 – 3,8733x3 2<br />
To follow the influence of independent<br />
variables exerted on dependent variable Y, on the<br />
base of presented data in table 2 we realised 3D<br />
representations of response surfaces (figures 2 ÷<br />
4), diagrams which contain the representation of<br />
dependencies Y=f(X1,X2), Y=f(X1,X3) și<br />
Y=f(X2,X3), when the 3 rd independent variable is<br />
constant and equal with the adequate value of<br />
experimental field center.<br />

Both in resulted mathematical model<br />
equation and in graphical representations we can<br />
see that all three independent variables exert a<br />
positive influence on variable Y, but from all the<br />
temperature (X3) is the most important for<br />
increasing the quantity of pigment ingrained on<br />
wool fibre. This can be observed most clearly<br />
when we analyse the variation of ingrained<br />
pigment quantity for a single parametre, the other<br />
two being constant (figure 5).<br />
Figure 5. Influence of the three variables on purpose<br />
function Y<br />
We can see that purpose function Y has the<br />
following values:<br />
x1 cod = 0 x1 real = 65 minutes<br />
x2 cod = +0,5 x2 real = 0,720 g/l<br />
x3 cod = +1 x3 real = 64 °C<br />
So, we can say that the maximum effective<br />
power for carthamin quantity absorbed by wool<br />
fiber has been obtained in the above conditions.<br />
The overhaul of 64 °C (x3 cod = +1) temperature,<br />
leads to a decrease of tinctorial effective power,<br />
which can be explained by the fact that at<br />
temperatures higher than 65 °C takes place a<br />
turning of colour from red to yellow.<br />
84<br />
CONCLUSION<br />
Both from the analysis of obtained<br />
mathematical model equation, and from diagrams<br />
we can can see that the influence of parametre x3<br />
(temperature) is higher on the effective power of<br />
reaction of dyeing wool fibres with carthamine.<br />
We established the optimal values of<br />
investigated parametres to obtain a maximum<br />
effective power of dyeing:<br />
x1 = 65 minutes<br />
x2 = 0.720 g/l<br />
x3 = 64 °C<br />
The mathematical modelling of dyeing<br />
process of natural protean fibres (wool) with<br />
natural pigments, has shown the fact that the<br />
quality index doesn't increase constantly with the<br />
increase of the values of the three investigated<br />
parametres, dependencies presenting both<br />
minimum and maximum points.de bază<br />

Research undertaken over the past decades have shown that due to the antioxidant capacity of natural pigments, their<br />
use in the food industry represents an immeasurable therapeutic potential for maintaining human health by preventing<br />
cardiovascular diseases, the risk of cancer and other imbalances caused by daily stress and by the disorganized lifestyle<br />
of modern man.Plants are established sources of industrial, pharmaceutical and aromatic compounds, which have been<br />
for milleniums the main source for obtaining bioproducts essential for the survival of the fauna. Dyes are natural or<br />
synthetic organic coloured substances, which absorb light in the visible part of the spectrum and have the property of<br />
colouring the substrate they are applied to.<br />
Key words: natural dyes, food industry, food dyes<br />
Always the inanimate nature has represented<br />
true bio-chemical factories which provided<br />
phytochemical compounds used in different<br />
industries like pharmaceutical products, food,<br />
cosmetics, agrochemical products.<br />
The natural dyes are natural organic or<br />
coloured synthetical substances, which absord light<br />
in the visible domain or UV of spectrum and have<br />
the property to adhere and colour the supports<br />
where they have been applied.<br />
At the moment there are homologated and<br />
spread more and more functional foods ,drinks<br />
,seasonings, special prepared products etc, which<br />
include in their manufacturing recipes some natural<br />
substances, dyes also, with invigorating,<br />
stimulating or protective medicamentary effects,<br />
extracted from the best known or appreciated<br />
cultivated plants or wild flora (Beceanu, D., 2010).<br />
Because the food processing takes place at<br />
high temperatures and because the natural dyes are<br />
not stable enough in these conditions, from<br />
commercial reasons in food industry and not only,<br />
there are dyes added to them to improvise the<br />
color and reduce the effects of its dissipation.<br />
The first used natural dyes were those of<br />
vegetal origin like: red obtained from roots of<br />
plants from Rubiaceae family, indigo extracted<br />
from plants from Indigofera family, blue extracted<br />
from campeachy wood and less those of animal<br />
origin.<br />

The dyes have their colour because in their<br />
molecule exist groups of atoms capable to absorb<br />
selectively components of white light. The<br />
radiations which are not absorbed are reflected,<br />
creating the sensation of colour. These groups<br />
which give the substance its colour are called<br />
chromophore groups, groups „bringers of colour”.<br />
There are also groups which intensify the colour of<br />
certain auxochrome groups.<br />
MATERIAL AND METHOD<br />
For this paper we reviewed a vast specialty<br />
bibliography about the industry of vegetal pigments<br />
used in food industry, comprising both internet pages,<br />
specialty databases and scientific papers presented<br />
at different symposyums from our own country and<br />
abroad.<br />
RESULTS AND DISCUSSIONS<br />
Food dyes are part of the food additives<br />
category, classified according to CEE schedule and<br />
have codes from E100 to E200. Some are<br />
separated from natural sources, for example<br />
curcumin E100, is an yellow dye known as „Indian<br />
saffron”, E120, red dye obtained from teguments<br />
of some insects. Other dyes are synthetical<br />
(Cercasov, C., 2005).<br />
Extracts from vegetak tissues contain lots of<br />
substances with phenolic functional groups, which
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
are part of different classes of organic compounds.<br />
Their systematization provides difficulties, because<br />
most of the natural compounds have mixed<br />
functions and can be ascribable to different classes<br />
at the same time.<br />
From a chemical point of view, the vegetal<br />
dyes are vegetal substances of secondary origin<br />
and can be classified in: chlorophyllian or<br />
porphyrian (green pigments from green plants),<br />
carotene pigments (yellow pigments from fruits<br />
and vegetables), flavones dyes, quinone pigments<br />
and indole pigments (Pascal, S.M., Veronique, C.,<br />
2006).<br />
Chlorophyllian dyes (E140) (fig. 1) are<br />
extracted from green raw materials (leaves) as<br />
deficient in proteins as possible, which are a source<br />
of contamination.<br />
Figure 1 Chlorophylle structure<br />
Usually it is obtained from nettles or spinach<br />
by extraction with the help of acetone, ethanol,<br />
methyl ketone and dichloromethane.<br />
It is used in oils, chewing gum, instant<br />
soups, sweets.<br />
Carotene dyes (E160) represent a group of<br />
pigments which are obtained in various forms and<br />
compositions and have colours from yellow to red,<br />
being represented by pro-vitamin A (alfa– figure 2,<br />
beta and gama carotene).<br />
Some products are more expensive and some<br />
are cheaper, like crocin from saffron (Crocus<br />
sativus), or oleoresin extracted from paprika, with<br />
capsanthin, have a high price. At the opposite pole<br />
there are lycopene from tomatoes, an yellow<br />
pigment extracted inclusively from residual peels<br />
resulted from tomato paste manufacturing (Cotrău,<br />
A. cited by Beceanu, D., 2009).<br />
86<br />
Figure 2 α-carotene structure<br />
Multiple studies emphasized that for the<br />
animal life, the main role of carotenes is that of<br />
predecessor in synthesis of vitamin A, which is an<br />
essential component in daily human diet, because it<br />
is implied in preventing cancer and cardiovascular<br />
diseases. In USA the average daily consumption is<br />
of aproximatively 6.5 mg/person and in Europe of<br />
aproximatively 14 mg/person (Socaciu, C., 2008).<br />
In carrots there accumulated around 7-8<br />
mg/100 g carotenes, of which 4 mg betacarotene.<br />
Yellow genera contain a smaller quantity than the<br />
red ones.<br />
They are used for colouring butter,<br />
margarine, in coffee cakes, sweet drinks or milk<br />
products.<br />
Flavone dyes are secondary metabolites<br />
with the widest spread from vegetal polyphenols<br />
category which contain in their molecule a pyran<br />
or furan condensed heterocycle with a benzene<br />
ring. Another benzene ring is coupled to the<br />
heterocycle (fig. 3). The rings have hydroxyl<br />
groups, which determine the phenole character of<br />
these pigments. These compounds determine the<br />
colour of flowers, fruits and even leaves:<br />
chalcones, dihydrochalcones, aurones, flavones,<br />
flavanoles, (yellow compounds), dihydroflavanoles,<br />
flavones, flavanoles, flavonoids (leucoantocianidins),<br />
antocianidins (red, blue or violet<br />
compounds).<br />
Figure 3 Flavylium cation's structure and numbering<br />
Antocyanin dyes (E163) are natural<br />
glycosides which in plants are represented by six<br />
compounds: cianidin-3-glucoside (E163a) – red<br />
colour; delphinidin-3-glucoside (E163b) blue;<br />
malvidin-3-glucoside (E163c) mauve;<br />
pelargonidin-3-glucoside (E164d) orange;
peonidin-3-glucoside (E164e) red-brown and<br />
petunidin-3-glucoside (E165f) dark red.<br />
Antocyanins are the widest spread pigments.<br />
These pigments exist abundantly in nature and are<br />
responsible for the red,blue or violet colour of<br />
flowers and fruits (Devies, K. D., 2004).<br />
Their colour is due to the degree of<br />
hydroxylation or methoxylation. Those with<br />
hydroxyl groups have a ruby red colours and those<br />
with methoxyl groups have a blue colour (Țârdea,<br />
C., 2007).<br />
The daily dosage authorised by European<br />
Union for E163 is of 200 ppm pure pigment<br />
(Pascal, S.M., Veronique, C., 2006).<br />
The industrial sources for obtaining the<br />
E163 dye are: peel and mash of red grapes,<br />
cabbage and beet, cranberries, blackberries,<br />
cherries, raspberries etc.<br />
E163 dye is used for colouring alchoholic<br />
and non-alchoholic drinks, natural juices, in pastry.<br />
Xantophyll (E161) are a group of yellow<br />
dyes, except E161(g) which is orange. They are<br />
obtained from plants by extraction with the help of<br />
hexane. In this category are: flavoxanthin (E161a),<br />
lutein (E161b), cryptoxanthin (E161c), rubixanthin<br />
(E161d), violaxanthin (E161e), rodoxanthin<br />
(E161f) and canthaxanthin (E161g). Excepting<br />
lutein and canthaxanthin, they are not found on<br />
market, but they are part of a normal diet. They are<br />
harmless, except canthaxanthin which damages<br />
retina.<br />
Chalcone dyes (curcumin E100)<br />
It's a yellow-orange dye, obtained from the<br />
root of Curcuma longa (indian saffron), insoluble<br />
in water, but soluble in ethanol and acetic acid. It<br />
can be obtained synthetically also.<br />
It is used as polysorbate of curcumin or<br />
curcumin powder disolved in alcohol.<br />
It is used for pickles, mustard, cheese,<br />
margarine, sweets or fish products, meat products,<br />
jam, marmelade.<br />
For the purpose of protecting population's<br />
health, food dyeing should be realised only with<br />
dyes accepted by current laws.<br />
Conditions for a dye:<br />
should not be toxic or carcinogenic at different<br />
levels of use;<br />
should not contain toxic contaminants;<br />
should have solubility adapted to its<br />
incorporation in watery phase and/or in lipid<br />
phase from food product;<br />
should not give the food product where is<br />
introduced a particular taste or smell;<br />
should be stable at light when it is introduced in<br />
product;<br />
87<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
should not be affected by the temperatures at<br />
which it is made the termal treatment<br />
(pasteurization, boiling, sterilisation);<br />
should be stable during the storage of the<br />
product where it was introduced;<br />
can be emphasized in the food product by<br />
adequate analytic techniques;<br />
should be available and rather economical price<br />
wise;<br />
should be approved by the current health<br />
legislation.<br />
Practically, the dyes are chosen according to<br />
affinity because generally food contains both<br />
hydrophilic and lipophilic components. That's why<br />
it was opted for initiation of studies for the purpose<br />
of obtaining food dyes with mixt function,<br />
hydrophilic-lipophilic with tinctorial polyphasic<br />
effect.<br />
The industrial sources of obtaining natural<br />
dyes for use in food industry are:<br />
from peel and mash of red grapes, beet and red<br />
cabbage, blueberries,cranberries, blackberries,<br />
cherries, raspberry (anto-cyanin);<br />
cayenne (capsanthin);<br />
tomatoes (lycopene).<br />
CONCLUSIONS<br />
Despite many challenges, the inanimate<br />
nature continues to represent the main supplier of<br />
phytochemical compounds used both in food<br />
industry and in other industries.<br />
Despite the disturbance of natural balance<br />
and unlimited exploitation of these resources, a rise<br />
of work force cost and technical or economical<br />
difficulties of plant cultivation from spontaneous<br />
flora, in some developed countries they are more<br />
and more interested in obtaining natural pigments<br />
by unconventional methods through new<br />
biotechnologies and modern techniques of cell and<br />
vegetal tissues cultures.<br />
Obtaining positive results represents the first<br />
step in elaborating applicable methods on an<br />
industrial scale in food, pharmaceutical, textile or<br />
cosmetic industries.<br />
Until now, in Romania, the production of<br />
natural dyes on an industrial scale has been<br />
completely neglected by concerns which have as<br />
object of activity vegetable and fruit processing,<br />
from their residues, like it is done in most of the<br />
developed countries from Europe and in the world.

CADMIUM PRESENCE IN AGRICULTURAL SOILS<br />
FROM IASI METROPOLITAN AREA<br />
Mariana VOLF 1<br />
e-mail:mariana.volf@uaiasi.ro<br />
The work is part of an extensive study, conducted over two years, which followed the main monitoring mechanisms and<br />
relationships involved in the trophic chain soil-plant-animal in an determined area, and continuing with the<br />
determination of quality indices of agro-livestock production, as it is known that for agricultural products, food value<br />
and quality are assessed by the content of nutrients. Food security depends on the efforts of each partaker in the food<br />
chain, from farmer to consumer. The first step is the manufacturer's control, maintaining standard requiring specific<br />
methods and techniques with adequate supervision, which verifies food quality, provenience and processing technology<br />
used for obtaining it. This paper presents results of the cadmium content in agricultural soils from two locations<br />
neighboring Iasi, forage crops area belonging to the Research Station for Cattle Growth Dancu and SC "Daniela" SRL<br />
Răducăneni-Iasi. It is widely recognized accumulation of cadmium in the environment due to activities of non-ferrous<br />
metal industries and the burning of fossil fuels. Due to the high bioavailability of Cd to plants, plants absorb easily<br />
translocated metal in soils containing 2-15 ppm Cd. The present study focused on the determination of cadmium in the<br />
first level from the trophic chain - soil, Cd accumulation over limits has a harmful effect in animal nutrition. For both<br />
sites, cadmium concentration exceeded the maximum permissible ground level but not the alert value of 3.0 mg / kg -1 .<br />
This is why the study undertaken, the research starts cadmium concentration in soil, taking into discussion two adjacent<br />
areas of Iasi, where are areas with a potential risk of exceeding the permissible limits, forage crops being influenced<br />
from industrial emissions.<br />
Key words: cadmium, soil, forage<br />
Heavy metals - Cu, Cd, Zn, Pb, Cr, Co, Ni,<br />
Mn, Fe – known as trace elements due to its low<br />
content in plants and soil, are chemical elements<br />
common to all soils (Budoi, Gh., 2001). Their level<br />
of abundance is between the percentages (%) and<br />
parts per million (ppm). In some cases, their<br />
concentration in soil exceeds the maximum<br />
concentration range where the effect is beneficial,<br />
causing disturbances of nutrition and thus<br />
inhibiting normal processes of growth and<br />
development of plants. The negative effect of<br />
heavy metals depends on their concentration and a<br />
series of physical and chemical properties that<br />
define soil such as: organic matter content, texture,<br />
reaction, redox potential (Davidescu Velicia.,<br />
Davidescu D, 1999).<br />
Determination of cadmium in the soil and<br />
maintaining its normal limits, thus preventing<br />
uncontrolled translocation in plant crops, which<br />
can be harmful in high concentrations and can be<br />
taken by the consumer as food or as forage by<br />
animal. Blood concentration of Cd ( human body)<br />
is 0.5 μg/100 ml and the process of removing it<br />
from the body is extremely slow. Ingestion of food<br />
1 University of Agricultural Sciences and Veterinary Medicine, Iasi, Romania<br />
containing heavy metals increase their<br />
concentration in tissue and occurs a series of<br />
metabolic dysfunction.<br />
This is why the undertaken study, starts with<br />
cadmium concentration in soil research, taking into<br />
discussion two adjacent areas of Iasi, where forage<br />
crops quality are influenced by industrial<br />
emissions, areas with a potential risk of exceeding<br />
the permissible limits.<br />
In blood, concentration of Cd is extremely<br />
low and stays low even if there is an excessive<br />
intake. Besides, Cd disappears rapidly from the<br />
blood which limits the diagnose of this parameter<br />
value. Human blood concentration is 0,5 Cd<br />
µg/100 ml, in urine from 2-22 µg /l, and may grow<br />
by more than 20 times for exposed persons. A<br />
maximum concentration of Cd is situated in renal<br />
cortex and testicular tissue. When you manage its<br />
concentration changes the Cd oral biopsy and its<br />
concentration in the kidneys, liver, hair and nails<br />
satisfactorily reflect exposure to Cd as opposed to<br />
the bone tissue, muscle and nervous systems that<br />
are protected against the original excess of Cd.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Cadmium can be absorbed in significant<br />
quantities and accumulated in different tissues and<br />
organs: heart, blood vessels, liver, kidneys,<br />
digestive tube, lungs, pancreas, bone marrow.<br />
Large quantities of cadmium are found in the blood<br />
(fixed by erythrocytes). In the muscle is small<br />
content, but enough to be dangerous to humans as<br />
durable. It induces proteinuria - the presence of<br />
excess proteins in the urine. Removal of cadmium<br />
from the animal takes place mainly through the<br />
feces and urine, bile and therefore less milk.<br />
Disposal from human body is extremely slow,<br />
about 20 years, fact that determine its increase in<br />
tissues as well as several metabolic dysfunctions.<br />
MATERIAL AND METHOD<br />
The research took place at the Research<br />
Station for Cattle Dancu that the administrative point<br />
of view is on land of the commune Holboca territory<br />
and on municipality of Iasi, in wich main soil types are<br />
chernozems, with typical subtypes, bills of exchange<br />
and argic, prevailing subtype classically cambic<br />
chernozem, mezocalcaric poorly degraded and into<br />
sheep farm Raducaneni, SC. Daniela Ltd.<br />
Raducaneni-Iasi dominated by an aluviosol gleyic,<br />
salt pelic, proxicalcaric, clay loamy / clay lutoasa,<br />
evolved on a gleisol cenic. Soil samples were<br />
collected from the upper horizon (0-20 cm) of<br />
agricultural land in two locations, Dancu (6 samples)<br />
and Raducaneni (7 samples).<br />
Sampling of soil, the most important operation,<br />
harvesting was done on plots with agrochemical<br />
probe, the depth of 0-20 cm. Each composite sample<br />
of soil samples consisted of 25 to 30 part, in the best<br />
area of land cultivated with some crops. Area that has<br />
been a mixed sample ranged from 2-5 ha to field<br />
crops and pastures and hay fields 5-20 ha depending<br />
on the relief.<br />
90<br />
Samples were dried in oven for 3 hours at 105<br />
° C, then brought to a grain size ≤ 0.02 mm.<br />
Disaggregation of soil samples for cadmium<br />
determination: treatment with perchloric acid<br />
concentrated and nitric acid concentrated, in two<br />
stages, on a sand bath with 400-450 ° C temperature.<br />
The solutions were brought into 100 ml volumetric<br />
flask with nitric acid 2%. In each flask was added, 10<br />
ml CsCl 1% concentration, before being brought to<br />
the 100 ml volume. Cadmium has been determined<br />

significant overruns values, respectively 0.8994<br />
and 1.1808 for AV8 and AV4 sample. For location<br />

In this research, is found in location<br />
Raducaneni like all sampling points are significant<br />
over runs, respectively 0.8994 and 1.1808 for AV8<br />
sample AV4. For location Dancu, overtaking from<br />
the maximum permissible values are also larger<br />
and ranges from 1.1142 to 2.7760 for sample AV7<br />
until AV6.<br />
It is worth noting that for both locations, the<br />
values of cadmium content in soil do not exceed<br />
the alert level is 3.0 mg • kg-1 (Fig. 1)<br />
CONCLUSIONS<br />
Cadmium is a potentially toxic metal, high<br />
cumulative and accumulate in the environment,<br />
mainly due to the activities of non-ferrous metal<br />
industries and the burning of fossil fuels.<br />
In the Raducaneni area cadmium<br />
concentration ranged inside 2.1142 µg/g and<br />
92<br />
2.7760 µg/g and in the Dancu, the concentration<br />
ranged from 1.8994 µg/g and 2.1808 µg/g. For<br />
both sites is not exceeded the alert level of 3.0 mg<br />
• kg -1 .<br />
These values give us the right to affirm that<br />
fodder plants growing in these areas, acquired and<br />
stored over the limits cadmium that is placed in<br />
normal insurance state of soil and there is the real<br />
danger to be ingested by feeding the animals which<br />
induce multiple malfunctions.<br />
Enrich the soil with Cd over the normal<br />
range may be due to various factors: anthropogenic<br />
pollution caused by industry, fertilizer use in<br />
agriculture, the upward movement in soils due to<br />
repeated precipitancy (Dumitru M., et al.,1994).<br />

Catering undertakes, by size and its characteristics, an important work load. Achieving economic and social functions is<br />
directly related to available material and human resources. The defining role of human resources is dependent on<br />
meeting the needs of consumers, on the one hand, economic performance and efficiency, on the other. An important<br />
role in achieving the tasks assigned to the food sector is the preparation and structure of staff recruited and trained to<br />
perform operations of making dishes and serving consumers. Staff selection must be made so as to meet present and<br />
future requirements for each function, to ensure human adaptation to his work, his job. In "Bolta rece" restaurant, the<br />
main skills required by managers are: physical and sensory skills (physical harmonious constitution, speed reaction,<br />
agility and motor skills, visual acuity and color); intellectual ability (good observation, demonstrating initiative, clearly<br />
in thinking, good memory, ability to think rationally, specific, fast, rich language, coherent, convincing) professional<br />
skills (general knowledge). Rezumatul redactat în limba engleză (10-15 rânduri, cu referire expresă la rezultatele<br />
cercetărilor).<br />
Key words: catering, human resources management, recruitment, skills<br />
MATERIAL AND METHOD<br />
For carrying out the work it was called for case<br />
study, as a major research strategy and the analysis<br />
of firm level performance using Bolta Rece restaurant<br />
manager interview in Iasi. For data collection and<br />
analysis we used qualitative research techniques and<br />
instruments, analysis of internal documents, job<br />
descriptions and interviewing employees in the<br />
departments.<br />
RESULTS AND DISCUSSIONS<br />
Catering issues and its role in national<br />
economy can not be separated from the functions<br />
which it fulfills. Viewed from a social perspective,<br />
the catering meet major the goal for public health<br />
care. The catering sector has, due to the work that<br />
it carries an important place in economic and social<br />
life in household consumption needs. Addressed in<br />
terms of labor policy catering is, on the one hand, a<br />
way to increase jobs, and on the other hand, one of<br />
the most effective ways to train the female<br />
population in social and economic activities<br />
(Brezuleanu, S., și colab., 2011).<br />
Due to its more complex character, under<br />
the many factors that currently exist in the<br />
economic and social life, restaurant business takes<br />
a number of features which completes the<br />
1 University of Agricultural Sciences and Veterinary Medicine of Iasi<br />
scientific objectives and tasks and different<br />
perspective but from other sectors of the trade<br />
(Dionisie C., 2002).<br />
Catering peculiarities arise from specific<br />
activities and this means that: is essentially a<br />
consumption outside the home (house), is<br />
influenced in a very important phenomenon of<br />
tourism, such a pronounced seasonal prices and the<br />
policy is the specific complex catering business<br />
(which includes production processes, marketing<br />
and service) and prices need to differentiate from<br />
one unit to another, depending on their specificity,<br />
the degree of employment and quality of services<br />
(Emilian R., 1999).<br />
Knowing that a number of features derive<br />
from the very content of catering processes (forms,<br />
methods and tools of accounting and control, the<br />
expenditure pattern of movement), we note that<br />
learning and knowledge of these features have vital<br />
importance in establishing principles and criteria of<br />
management and the organization of catering<br />
business because they directly reflect the efficiency<br />
indicators used in the catering of “Bolta rece”<br />
restaurant Iasi.<br />
“Bolta rece” restaurant is a local (Romanian)<br />
restaurant, classified in category I, under certificate
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
no. 216/25.04.1994 issued by the Ministry of trade<br />
and tourism.<br />
BOLTA RECE is a restaurant that has<br />
inherited the building, an name and fame of old<br />
local of Iasi and frequente in different periods, by<br />
well known cultural and artistic personalities. The<br />
neighborhood has historical monuments such as St.<br />
Theodore Church, Mihai Codreanu Memorial<br />
House, University of Medicine and Pharmacy.<br />
The unit is located in an area near the city<br />
center, advantage diminished, however, by the<br />
inconvenient access (narrow streets and little<br />
known), especially for foreigners from the city.<br />
The catering complex comprises: restaurant,<br />
cellar, terrace with seasonal use.<br />
The unit has 140 seats in the restaurant and<br />
wine cellar, 60 seats on the terrace.<br />

Besides these, there are a number of features<br />
in the design and foundation plans and indicators<br />
referred. These are specific indicators, their content<br />
and methods of determination of their scope and<br />
importance to the restaurant activity. From the<br />
discussions with the restaurant manager it shows<br />
that the main indicator to characterize the activity<br />
is "the catering sales volume". In developing and<br />
funding this indicator, the manager shall, with<br />
familiar elements (study the customers<br />
requirements, their financial possibilities,<br />
analyzing the results of earlier periods), the need to<br />
provide attractive menus, rational people, the<br />
changes report that food needs are personal<br />
household satisfied by purchases of goods and<br />
services through catering.<br />
Catering undertakes, by size and its<br />
characteristics, an important work load. Achieving<br />
economic and social functions is directly related to<br />
available material and human resources. The<br />
defining role of human resources is dependent on<br />
meeting the needs of consumers, on the one hand,<br />
economic performance and efficiency, on the<br />
other.<br />
In this context, employing specialized<br />
personnel, in compliance with its optimal<br />
proportions and structures, ensuring a level of<br />
94<br />
preparedness, the catering acquires new values.<br />
Results of analyzed catering unit depend on how<br />
the human potential of forces acting on material<br />
and financial interdependence. For this to be<br />
solved, the issues of selection and coverage of<br />
division of labor and organization of the best workteams.<br />
To ensure a climate of detente and mutual<br />
respect, the employed workers in the hall for<br />
serving consumers must meet certain qualities:<br />
moral, psychological, intellectual, and physical<br />
training. These criteria take into account the<br />
formation manager, personnel selection and<br />
promotion used unit he leads.<br />
In deciding the recruitment, the human<br />
resources manager is considering staffing needs for<br />
each department. This is determined by the<br />
following components: capacity restaurant sales<br />
volume and structure, workload and time required<br />
for serving and preparing dishes.<br />
Personnel manager selection is made so as to<br />
meet current and future requirements for each<br />
function provides human adaptation to work, the<br />
specifics of his job. Whenever the manager is a<br />
choice between two people, we can say that<br />
practically make a selection criterion when<br />
considering the preparation, the skills for that job<br />
and workplace characteristics.<br />
Professions in the catering sector are<br />
evolving and being able to expand or shrink<br />
according to economic phenomena, influencing<br />
various social and technical sectors. For example,<br />
the profession of waiter knows significant<br />
numerical reduction as a result of new forms of<br />
sale: self-serving, comet by automatic, units with<br />
payment at sale etc.. At the same time, the appear<br />
trades in November about precisely these forms of<br />
service.<br />
Recruiting human resources also has in view<br />
the job analysis and design work, because the<br />
results of these activities, thus job descriptions and<br />
specifications are essential in the recruitment<br />
process. This means that the person who recruits or<br />
hires must have the necessary information on job<br />
characteristics, and qualities of the future owner.<br />
For recruitment, restaurant manager of<br />
"Bolta Rece" appeals to two distinct ways, namely:<br />
individual orientation to employment in the<br />
catering sector, which is based on skills and<br />
knowledge to find his job and the best selection (as<br />
opposed to orientation) requires knowledge of the<br />
job for which you should seek the most suitable<br />
one. For successful selection of a training manager<br />
made the greatest number of candidates, thus<br />
giving people a choice appropriate for each post.<br />
For selection the law in force is used in several<br />
forms and procedures such as aptitude tests,
quizzes, review the evidence base work, post<br />
certificate etc.<br />
The recruitment logically follows the<br />
planning of human resources as aimed at<br />
identifying and attracting the competitive<br />
candidates to fill the net or additional personnel.<br />
This means that the restaurant recruitment efforts<br />
and methods used are dependent on human<br />
resource planning process and the specific<br />
positions to be filled. Knowing in advance or as<br />
anticipation the need of staff, due to human<br />
resource planning process, allows a smooth<br />
running and more likely successful recruitment<br />
process.<br />
Selection of personnel is one of the basic<br />
activities of human resource management, is<br />
usually made in the personnel department, but<br />
which is the responsibility of managers at different<br />
levels. Restaurant management has always been<br />
concerned with selection of staff, as this activity<br />
can be very expensive if you hire people who<br />
ultimately are considered inadequate.<br />
Therefore, the selection of staff is<br />
considering the fact that people differ from one<br />
another through a series of qualities, and posts, in<br />
turn, differ by a number of requirements they<br />
impose to candidates.<br />
In the Bolta Rece restaurant, recruitment and<br />
selection of human resources is in line with<br />
recruitment policy of the company.<br />
Criteria of behavior used for employees are:<br />
punctuality, acceptance and respect for the work<br />
program, delays and absences recorded frequency,<br />
presentation and order at work - correct attire and<br />
behavior, professional discipline and work, team<br />
spirit - supporting colleagues own initiative, labor<br />
relations, collective attitude towards work, maturity<br />
and behavior generally calm, self-control,<br />
adaptability to various works, presence of mind,<br />
proper performance of duties, dignified behavior at<br />
work.<br />
The manager of the catering unit recruits,<br />
selects and makes proposals or approves hiring.<br />
There are certain requirements to be fulfilled by<br />
the persons to be engaged:<br />
• Temperament traits that relate dynamic<br />
events, how to respond to different stimuli, rapid<br />
movements and activities. Usually, everyone has<br />
great possibilities, but each is the owner of certain<br />
qualities that can only ensure maximum efficiency<br />
in some activities. In the restaurant business, the<br />
95<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
main features of temperament which the worker<br />
must meet are: sociability, communicative,<br />
efficiency, dynamism, optimism, self-adaptation,<br />
calm and patience in dealing with people,<br />
volubility;<br />
• Skills that are the sentimental side or the<br />
means by which the individual personality and<br />
abilities include those human, that it can achieve<br />
maximum social efficiency. In "Bolta rece"<br />
restaurant, the main skills required by managers<br />
are: physical and sensory (physical constitution<br />
robust and harmonious, reaction speed, agility and<br />
motor skills, visual acuity and color); intellectual<br />
ability (good observation, demonstrating initiative,<br />
clearly in thinking, good memory, ability to think<br />
rationally, specific, fast, rich language, coherent,<br />
convincing) professional skills (general<br />
knowledge).<br />
All these skills are specified for each<br />
function of the restaurant, according to table 2.<br />
CONCLUSIONS<br />
The catering sector occupies an important<br />
place in economic and social life in household<br />
consumption needs. Catering has an important role<br />
in production of products and dishes, and selling to<br />
the public.<br />
The successful application of human<br />
resource management system involves<br />
recruitment, a system of performance<br />
evaluation of a system of incentives to reward<br />
employees and results. Recruitment is the<br />
process of searching, locating, identifying and<br />
attracting potential candidates, the candidates to<br />
be selected, eventually representing<br />
professional characteristics necessary or best fit<br />
the requirements of current and future<br />
vacancies<br />
The restaurant staff qualification of Bolta<br />
rece is high, each being a high school or<br />
professional school graduate in catering, which<br />
provides excellent services.<br />
At this restaurant, the serving at the table is<br />
done by waiters who have specific Moldavian<br />
uniforms, composed of: shirt specific to the area, ,<br />
classic black trousers, specific to the area, classic<br />
shoes. Serving techniques are used as class unity<br />
and vary according to the menu, ordered in<br />
advance or a la carte.

STRATEGIES OF HUMAN RESOURCE PLANNING ON COMPARTMENTS<br />
IN INTEGRATED AGRICULTURAL UNITS<br />
Abstract<br />
Stejărel BBREZULEANU 1<br />
e-mail: stejarel@uaiasi.ro<br />
Strategic planning of human resources estimates the expected future demand of employees both qualitatively and<br />
quantitatively compares the application referred to human resources and the surplus or deficit of existing staff on<br />
organizational objectives. Human resources should be regarded as a factor in the evolution of an agricultural holding,<br />
under present conditions, where technological and managerial changes are imposed by the market with great rapidity.<br />
In these conditions, a good manager must manage material and human resources very precisely, form a working<br />
framework attractive to develop productive and creative capacities of his employees.<br />
In the company Comcereal S.A. Vaslui, the overall strategic planning is done early and its main objective is the<br />
development of production systems, continuous improvement of management systems and not least, specializing the<br />
personnel through continuous training in the workplace. Strategic planning of human resources is paramount,<br />
contributing to business strategy by identifying opportunities to better use existing human resources and showing how<br />
the lack of human resources application may adversely affect the proposed business plan, if no action is taken .<br />
Key words: strategies, human resource management, integrated farming units<br />
MATERIAL AND METHOD<br />
To present the results obtained by SC<br />
Comcereal SA Vaslui, there were used statistics in<br />
the unit records and official documents, and for<br />
processing and interpretation there were used<br />
diagnostic method analysis, investigation and<br />
correlation.<br />

S.C. Comcereal S.A. Vaslui is one of the<br />
most representative Romanian companies for<br />
agriculture, having a leading position among the<br />
companies in the industry. The investment in<br />

S.C. Comcereal S.A. Vaslui operates under<br />
Law 15/1990 and Law 31/1990 on organization<br />
and management companies, with multiple tasks to<br />
achieve market products such as: developing<br />
design studies and programs on the future<br />
development of the company and its products ,<br />
studying the market and society issues related to:<br />
raw materials, equipment, labor, financial and<br />
informational resources, research and utilization of<br />
all existing reserves, application of modern<br />
management, system objectives established<br />
periodically and approve the work program on how<br />
to achieve it, draw up specific programs to enhance<br />
the capitalization of resources, rational use of<br />
production capacity, size of labor productivity,<br />
reduce costs of production and circulation, ensures<br />
the production according to market demand<br />
Collaborates programs, provide staff worker with<br />
protective equipment specific work and jobs with<br />
high risk<br />
The labor force consists of employees with<br />
permanent personal contract and seasonal<br />
employees with fixed-term employment contract.<br />
Given the nature of agriculture, the<br />
employees work in the plant, during spring -<br />
summer - autumn, day light and on Saturdays,<br />
Sundays, according to weater needs and time.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
The livestock program is also adapted to the<br />
specific, the employees work in the morning from<br />
5-9 and afternoon, from 14.30 to 19.00 and on<br />
Saturday and Sunday in shifts.<br />
The strategies in the field of human<br />
resources start both from the overall strategic<br />
objectives defined at farm level and from the<br />
content of human resource management, but does<br />
not eliminate the major problems arising in<br />
previous years and which were only temporary<br />
solutions.<br />
This increase in staff may be placed on<br />
account of three existing positive aspects to the SC<br />
Comcereal S.A. Vaslui i.e.: go on developing the<br />
productive sector and not in terms of areas where<br />
there is a constant in recent years, but follows the<br />
line quality of products obtained in the SC<br />
Comcereal S.A. Vaslui investments in the<br />
98<br />
productive sector through the purchase of<br />
equipment performance is reflected in the structure<br />
because staff must be qualified to work with these<br />
machines, the administrative staff are to better<br />
management of material and financial resources<br />
that the society has.<br />
The staff has been increasing in the last<br />
three years and not only at the administrative level<br />
but also in the productive sector. If in 2009 the<br />
total was 532 people, in the year 2010 it reached<br />
543, and in the next year the number of staff<br />
reached 552 people, the growth is higher although<br />
the number of administrative staff directly<br />
involved in production increased more (fig. 1)<br />
Overall and by staff, the human resources of<br />
SC Comcereal S.A. Vaslui can be structured as<br />
shown in table 1.<br />

In the company Comcereal S.A. Vaslui the<br />
overall strategic planning is done early and its<br />
Table 1<br />
main objective is the development of production<br />
systems, continuous improvement of management
systems and not least, specialized personnel<br />
through continuous training in the workplace.<br />
This process is quite difficult because<br />
production activity in this area is closely linked to<br />
environmental conditions, so planning can be made<br />
only at estimates but consider the potential risks<br />
that such activity is subject productive.<br />
The planning for the society is preceded by<br />
an intermediate step is to find the best ideas for<br />
improving the system through a form that each<br />
employee brings to the three proposals which it<br />
belongs. The operation is done in an organized<br />
manner, that the responsibility lies not only for<br />
managers but it gradually delegates the following<br />
hierarchical levels, thus, enabling the process to<br />
improve the overall system, involving all<br />
employees.<br />
The data collected by line managers are<br />
centralized (at the plant culture, the bread factory<br />
and the farm livestock), are analyzed and retained<br />
only those ideas that can be implemented and can<br />
improve the system as a whole.<br />
The personal strategies are defined as the<br />
intentions HRD Manager at SC Comcereal S.A.<br />

requirements to be met in this area, to facilitate<br />
organizational goals.<br />
The directions of development strategies<br />
pursued by the management staff of the SC<br />
Comcereal S.A. Vaslui, are: ensuring and<br />
selection, training and employee development,<br />
performance evaluation, reward employees,<br />
relations with employees<br />
The human resource planning includes the<br />
following actions necessary within the<br />
organization: staff qualification analysis, the<br />
average age of staff organization analysis, analysis<br />
of staff turnover.<br />
In the Comcereal S.A., the staff of the<br />
company is one of 552 persons, of which over 85%<br />
have a qualification in a particular area whether we<br />
refer to those directly productive, or adjacent to<br />
those involved in the production process.<br />
The workforce skills analysis focuses on two<br />
aspects, the basic characterization qualification<br />
situation at a time, progress, and how skilled labor<br />
is used. These matters may structure the types of<br />
training staff and improving skilled labor.<br />
For synthetic characterization of the level of<br />
the personnel will analyze the data in table 2 Table 2<br />

Total 532 543 552<br />
The evolution of the number of people in<br />
society Comcereal SA can be found in 2011 on<br />
each floor of training, more pronounced for those<br />
with specialized studies in a particular field. This<br />
can be explained by a permanent staff adapt to new<br />
agricultural market trends or the bakery, where<br />
evolution is an extremely fast.<br />
In terms of age, S.C. staff Comcereal S.A.<br />
fits the best age for that sector. It intersects each<br />
department of activity as people with professional<br />
experience and some with little experience but<br />
with plenty of initiative, creative spirit and keen to<br />
progress professionally.<br />
For a more precise analysis it should be<br />
examined the labor movement, i.e. movement of<br />
personnel over a period (inputs and outputs)<br />
determined by socio-economic reasons such as<br />
retirement, death, transfer, activity restriction<br />
(table 3).<br />
The number of persons left in S.C.<br />
Comcereal S.A. Vaslui although it is growing in<br />
the year 2011, total negative impact on the<br />
dynamics of movement, which in the same year<br />
2011 decreased from the previous year, this being<br />
possible due to increased inflows of 10.9%.<br />
Strategic planning in S.C. Comcereal S.A.<br />
takes place in several stages: identifying mission of<br />
SC Comcereal S.A. Vaslui, examining the external<br />
environment, internal analysis, forecasting<br />
organization development, implementation and<br />
review of development plans.

The structure of staff S.C. Comcereal S.A.<br />
we see a continuous specialization of those active<br />
in society, with the year 2011 a total of 25<br />
personnel in order to conduct business in a most<br />
professional responsibilities and the business<br />
decisions that executed. Besides these there are in<br />
the organization an internal training through<br />
training programs, where employees are trained in<br />
a sector so that it can replace at any time a fellow<br />
professional on the same line.<br />
CONCLUSIONS<br />
Large farms and structure are more flexible<br />
and integrated human resource management as a<br />
strategic activity, and this is reflected in a reduced<br />
conflictualitate good economic and financial<br />
results. It requires robust policies promoting staff<br />
motivation in farms.<br />
The concept of strategic planning in SC<br />
Comcereal S.A. is defined as the forecast of<br />
business organization that allows it to determine,<br />
quantify and continuously maintain a permanent<br />
connection between resources and objectives on<br />
the one hand and market opportunities on the<br />
other.<br />
Table 3<br />
Research conducted at S.C. Comcereal S.A.<br />
Vaslui has shown that this very important aspect of<br />
management. Management is needed at farm level<br />
to consider human resource as a strategic asset and<br />
to integrate human resource management in the<br />
strategic management of the company.<br />

The purpose of this paper is to identify ways to increase economic performance accommodations by implementing<br />
effective strategies. In this price range strategies were analyzed weekly, prices vary according to season, prices and<br />
prices associated with loyalty. Each of these methods were analyzed in a case study in a unit of a unit of travel. The<br />
results obtained showed the need to consolidate and develop their own strategies for marketing of tourism services.<br />
Key words: services price, economic efficiency, economic security<br />
The price is influenced by supply and<br />
demand characteristics and the power relations<br />
between them. The relationship between demand<br />
and supply of services meet two situations (Kotler<br />
Ph. And Armstrong G , 2008).<br />
The elasticity of demand for a large part of<br />
the services is high, the greater market power is<br />
held by customers. They can choose to buy certain<br />
services to and make it their own if the price is too<br />
high. The price of these services will be influenced<br />
mostly by customers.<br />
In the second situation is vital to customer<br />
service and a high degree of difficulty. In this case<br />
customers are relatively powerless in relation to<br />
which this time bidders have the strength to<br />
determine the price (Plumb I. and Ionescu<br />
Manuela, 2004).<br />
However, all bidders are those who tempers<br />
prices through competition. However, for many<br />
services such mental association is found in the<br />
customers' service quality - great price "and even<br />
reverse" high price - quality services. This is the<br />
effect of psychological factors determining the<br />
market (Moga T. and Carmen Valentina<br />
Rădulescu, 2003).<br />
Pricing services is a constant concern of<br />
service providers because it is the means of valuing<br />
their effort. Its interest is to obtain as high a price<br />
to cover costs and achieve a profit margin. Buyer<br />
interest is to obtain services at the lowest possible<br />
price. It considers utility fee based disposable<br />
income and the effort and it makes one (Ioncică<br />
Maria, 2006).<br />
MATERIAL AND METHOD<br />
The working method used in this work has<br />
focused on economic analysis and case study on a<br />
tourist units. Unit that is the case study was<br />
researched in the paper this paper coauthored by<br />
undergraduate graduation.<br />
The results presented were the economic<br />
scenarios based on different marketing strategies.<br />
Used information from the unit's own documents<br />
researched and published documents on the official<br />
website of the Ministry of Finance.<br />
RESULTS AND DISCUSSIONS<br />
Economic analysis has sought ways to<br />
increase the economic performance of tourism<br />
facilities in ways to adapt prices to demand and its<br />
peculiarities.<br />
Given weekly price range of this strategy<br />
were determined five different thing. The first<br />
option is Vo-current version of a common tariff of<br />
75 lei per room during the weekend and on<br />
weekdays and a total of 460 tourists. In this<br />
situation shows that profit is 7.170 lei, with a profit<br />
rate of 24,2% and 30,6% safety margin. In this<br />
case tourism unit would record an annual profit of<br />
7.170 lei.<br />
If we consider the variant V1-variant when<br />
they differentiated prices on rooms for the<br />
weekend (80 lei), and during the week (60 lei), will<br />
be a disadvantage, since some customers coming<br />
weekend will be attracted by prices of the week<br />
and will accommodate at this time.

If we take another option to see how much<br />
pension will increase revenue, we can take V2variant<br />
version incorporating a great advantage. It<br />
could be that some tourists who come to the<br />
weekend tourist unit, will remain here another 1-2<br />
days, or will come 1-2 days earlier.<br />
There is also the possibility that some<br />
potential customers to come because of lower<br />
prices during the week.<br />
This version is slightly different from the<br />
previous one, although prices are the same and on<br />
weekends and weekdays. The difference lies in<br />
increasing the number of tourists during the<br />
coming week but the number is the same weekend.<br />
Because of this, there was a profit of 9.630 lei,<br />
higher than the original version, and than the<br />
version V1. The profit rate is 33,5% recorded<br />
increasing profitability threshold being 354, and<br />
the safety margin recorded a value of 31,9 %.<br />
Prices vary according to seasons<br />
102<br />
Table 1<br />
Besides these two types of efficiency, also<br />
include others, such as for example the variant V3drive<br />
tourists come from customers who calculate<br />
their average price per room on a tourist staying at<br />
the unit and will accommodate a common period,<br />
weekends and weekdays. This time it increases the<br />
number of tourists who come to drive tourists on<br />
weekends from 360 persons to 380 persons and the<br />
number of people who come during the week to<br />
160 people to 180 people. We observe that as the<br />
number of tourists increases both weekend and<br />
weekend will be an increase in all economic<br />
performance. Gross profit will record a value of<br />
11.470 lei, the profit rate will be 38,6% and the<br />
safety margin will record a value of 36,8%. And if<br />
this variant prices are the same as previous<br />
versions, that is 80 lei per room during the<br />
weekend and 60 lei per room during the week, the<br />
price per room / night.<br />

In this case will only increase the number of<br />
people who come during the week to 180 people,<br />
as were predecessor to 220 people. Profit made on<br />
the last version is 12.910 lei, and the profit rate of<br />
42,1% safety margin is 41.0%. Gross profit<br />
Table 2<br />
increases from one version to another, from 7,170<br />
lei from the original version to version 12.910 to<br />
V4.<br />
B. Prices vary according to season is<br />
differentiated pricing for different periods: specific
price in season and extra season specific price.<br />
Like the other strategy, note that this may 5<br />
pension options to maximize performance. Here<br />
we took into account a rate of 70 lei / room in<br />
season, and 50 lei / room in low season. The first<br />
variant V0 is the same as the previous scenario<br />
since remained a common price for the season and<br />
the season, achieving the same economic results.<br />
Next version, V1-one which requires that all<br />
visitors are interested to come to drive tourist<br />
season, and nobody wants to come during the<br />
season. Then it is apparent that the economic<br />
performance of the pension will fall to 4.870 lei,<br />
with a profit rate of 17,8%.<br />
The next variant, variants V2-is the<br />
disadvantage that some of the customers who came<br />
to drive tourist season decided to turn to during the<br />
season. Also here we see that there have been<br />
losses.<br />
So far we have illustrated situations where<br />
tourism unit could not obtain favorable economic<br />
Associated prices<br />

results. Following will bring increases in annual<br />
profit. V3-version means that in addition to<br />
travelers to the season, there are people who will<br />
come in season, variant that will lead to increased<br />
economic performance, recording a profit of 6170<br />
lei per year. Last option, V4-is version that will<br />
increase the number of people will come and will<br />
accommodate the season. Thus, it will increase<br />
revenue per room each year.<br />
In this case there was a continuous increase<br />
in gross profit. In version 1 and version 2 that have<br />
recorded the lowest values of gross profit a year<br />
before recovering.<br />
C. Prices associated with the case have<br />
proposed three options. The first version was V1<br />
version which some tourists will stay another day<br />
at half price or where these tourists will come a<br />
day earlier. We note that the strategy, there was a<br />
profit of 11.710 lei, and a profit rate of 38,2%.<br />

margin of safety rate (%) 30,6 24,6 47,1 55,7<br />
In addition to this model, we considered<br />
another variant, variant V2, which means that<br />
about 75,0% of tourists, to get two extra days of<br />
accommodation, and this situation will be further<br />
increases in the economic performance record. By<br />
using this option, tourism unit will record a profit<br />
of 17.030 lei, and a profit rate of 52,6%. V3 is one<br />
which requires that all tourists stay at tourist unit to<br />
stand two extra days. This option is a profit of<br />
21.710 lei.<br />
Gross profit increased from the original<br />
version (V0) of the 7.170 lei to V3, which saw a<br />
profit of 21.710 lei.<br />
D. Price of loyalty to gain new economic<br />
results, business tourism could give vouchers loyal<br />
tourists, aimed mainly at their return, either alone<br />
or accompanied by friends.<br />
In this case we took as reference the initial<br />
version, when not given vouchers and four<br />
variants, each generating more income as original<br />
Table 3<br />
version. We note that the prices are different from<br />
previous cases, so the weekend accommodation on<br />
a room will pay 75 lei / room, and for weekdays<br />
will pay 53 lei / room.<br />
From those presented so far, it has strengths<br />
and weaknesses. The first version V1 is not<br />
available to tourists vouchers, in which economic<br />
unit does not lose anything but the end result no<br />
further.<br />
The next version, V2-means that if some of<br />
the customers will come back with those vouchers,<br />
or will give to friends. Then, the unit will record<br />
certainly more economical results. Recorded as<br />
revenue of 11,730 lei, and a profit rate of 37,6%.<br />
Next version, V3-involves providing<br />
vouchers to the voucher, part of the 460 tourists,<br />
come with friends, and implicit in this situation,<br />
the voucher will double. Our gross profit in this<br />
situation will be 14.010 lei, and the profit rate of<br />
42,3%. Last option, V4-shows the highest price
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
during the week is equal to variable cost, in which<br />
case the safety margin is reduced, leading to a<br />
decrease in safety and business, with all that profit<br />
remains the same.<br />
In variants V0, V1, V4 gross profit recorded<br />
the same amount of 7.170 lei, while V2, profit rose<br />
to 11.730 lei, and V3 increased further to 14.010<br />
lei.<br />
E. Strategy assurance of additional<br />
services at the same price In this situation we<br />
have considered only two alternatives.<br />
If the first version V1 are highlighted<br />
additional services that are not approved by<br />
tourists, and therefore no additional variable costs,<br />
is the only indicator that will increase fixed costs<br />
Prices associated with vouchers<br />
104<br />
(17.290 lei). This will generate lower gross profit<br />
from a version to another, and lower profit rate<br />
from 26.2% to 21,8%. Safety margin is reduced by<br />
4,3%.<br />
The second option analyzes the situation in<br />
which some customers are attracted additional<br />
services and therefore would be a preferred tourist<br />
unit which that unit will increase demand for<br />
services. In this situation there will be a further<br />
variable costs increase by 5, a lei and fixed costs<br />
from 16.290 lei to 17.290 lei., Where customers<br />
will bring additional revenue at least equal to<br />
additional expenses. The strategy has been a<br />
decrease in profit from one version to another.<br />

ELABORATION AND IMPLEMENTATION OF TRACEABILITY<br />
ASSURANCE SYSTEMS SUNFLOWER<br />

The proposed work is to reveal the technical, economic and administrative systems development to ensure traceability<br />
chain sunflower. Components involved in these processes are to ensure traceability system design, adaptive<br />
management information requirements traceability, design and implement procedures for withdrawal of products,<br />
improving the system to ensure traceability of external verification and accreditation system to ensure traceability and<br />
ensuring economic efficiency specific traceability. Research methodology is centered on case study in SC Ulerom S.A.<br />
the city Vaslui unit that analyzed the implementation of the traceability system and economics effects of it. The results<br />
obtained show that traceability system implemented by the unit is functional but it costs is not justified in economic<br />
results achieved in the short term.<br />
Key words: food safety, traceability, return<br />
Traceability provides customers with<br />
traceability of a product road map to obtain raw<br />
materials to finished result product. It is the direct<br />
consequence of increasing consumer confidence in<br />
food purchased and therefore long term, the<br />
economic efficiency. Also, check the route through<br />
traceability of food products with a significant<br />
impact for end users to legislative bodies and for<br />
manufacturers of food processing (Mencinicopschi<br />
Gh., 2005).<br />
The main objective of traceability is to<br />
ensure total control over the products through<br />
individual and group identification, to intervene if<br />
the process of manufacture or market links with<br />
non-compliance is found or disadvantages of the<br />
product (Motoiu,R., 1994).<br />
In the food industry, traceability becomes<br />
particularly important because recordings are<br />
essential both legally and ethically. Traceability is<br />
important for producers and consumers. This is a<br />
solution for consumer protection and a means of<br />
control and responsibility for determining the<br />
product chain actors (Ioancea, L., Kathrein,I.,<br />
1989).<br />
To ensure order and control over production<br />
achieved in the organization should implement a<br />
system of identification and traceability. It is<br />
intended to provide information about where the<br />
causes of nonconformities and will help reduce the<br />
cost of remediation, when appropriate (Banu<br />
C.,2008).<br />

MATERIAL AND METHOD<br />
The main objective of this paper is to highlight<br />
technical, economic and administrative development of<br />
systems to ensure traceability chain sunflower.<br />
Research methods used include: documenting<br />
scientific ground on ways to implement the SC system<br />
Ulerom SA case study on how to ensure traceability<br />
system unit, systematic analysis on the design and<br />
implementation of system components to ensure<br />
traceability and economic analysis focused on key<br />
indicators of economic efficiency.<br />
The information used was obtained from the<br />
unit's internal documents and documents published on<br />
the official website of the Ministry of Finance.<br />
Dissemination of research presented in this work<br />
was done by a dissertation project co-authors of this<br />
paper.<br />
RESULTS AND DISCUSSIONS<br />
Implementation of internal traceability<br />
About the unit Ulerom S.A. was done using codes,<br />
documents and records, data management tools<br />
and procedures for withdrawal of products. Since<br />
the company has no obligation to use only one<br />
system of traceability, but also to provide evidence<br />
that doing so is essential that the system is<br />
documented.<br />
Traceability system elements in the SC unit<br />
Ulerom S.A. are operative as part of the company<br />
of other procedures such as procurement, quality<br />
assurance, etc.. The first step in establishing a<br />
traceability system is to analyze current procedures<br />
and operations to determine what factors are
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
already present and identify shortcomings in the<br />
transfer of information needed for traceability.<br />
Involved in producing components for<br />
ensuring traceability system are: ensuring<br />
traceability system design, adaptive management<br />
information requirements traceability, design and<br />
implement procedures for withdrawal of products,<br />
improving the system to ensure traceability of<br />
external verification and accreditation system to<br />
ensure specific traceability and traceability<br />
ensuring economic efficiency.<br />
A. Plan development and implementation<br />
system to ensure traceability of the company<br />
includes the following steps:<br />
1. Establishing an administrative team has<br />
designated role, establishing authority and<br />
responsibility for operation of the system to ensure<br />
traceability. It has a technological and an<br />
administrative component. Designated by the unit<br />
team S.C. Ulerom S.A. to ensure traceability is<br />
represented by an engineering technologist and<br />
administrative manager.<br />
2. Achieving flow diagram - flow diagram<br />
provides information on technological<br />
transformations that drive the product suffers from<br />
Review existing procedures and records<br />

purchasing raw materials to finished product<br />
delivery.<br />
3. Identify existing procedures existing<br />
procedures will be adapted and supplemented with<br />
specific procedures to ensure traceability. Existing<br />
procedures may include the procurement, quality<br />
monitoring mode, batch coding procedures etc.;<br />
4. Identification of existing records is the<br />
stage which is to identify current records and how<br />
they are produced in association with operations<br />
and products. This information is encrypted and<br />
written to provide the necessary documentation<br />
tracking system. Procedures and records include<br />
the name of the document and its location in<br />
reference to company records.<br />
5. Confirmation in situ confirmation that all<br />
information is intended to be found in some books<br />
or records that are kept in the manufacturing<br />
departments or offices.<br />
Structure of unit operations S.C. Ulerom<br />
S.A. is registered as a process diagram or a written<br />
record in a table that has the advantage of<br />
introducing references to specific written<br />
procedures or records.<br />

All documents required to ensure<br />
traceability of the process are dated and signed by<br />
the person carrying out the operations specified in<br />
the protocol procedure. Nature of the information<br />
contained in these documents will be approved by<br />
the administrative team in accordance with the law.<br />
B. Information Management<br />
In general and in particular the unit<br />
investigated traceability is primarily related to<br />
information management. When a product<br />
undergoes a transformation operation, information<br />
that relates to that product undergoes a change so<br />
that the link between product and store<br />
information. Changes may change the information<br />
are: the transfer, the addition, unification, division.<br />
1. The transfer is one of the most simple<br />
information processing operation. In this case, the<br />
product identification codes are transferred to the<br />
product while browsing the installation.<br />
Table 1<br />
2. Addition information is required during<br />
the process when new components are added<br />
technology or product is subject to operations that<br />
change the product composition of chemically or<br />
microbiologically. In this situation, continues to<br />
use the product identification code which is,<br />
however, unique process but records are filled with<br />
ingredients identification codes used or the<br />
operation performed.<br />
3. Unification of information occurs when a<br />
process step of combining several batches, each<br />
with its own identification code. In this case, the<br />
new group obtained shall be a new identification<br />
code, and records indicate the identification code<br />
of the components.<br />
4. Division information is used when the<br />
group is divided according to the requirements of<br />
the technological process or structure of the<br />
company product offerings. In this case, for each<br />
unit divided resulting assigned new identification
codes. Basically, the new code is assigned to the<br />
next stage of processing.<br />
For continuing operations, record the date<br />
and time separate consignment enters and exits the<br />
process. Labels do not contain all information<br />
needed to ensure traceability but links to<br />
documents providing this information. This<br />
condition is usually satisfied by using individual<br />
and unique batch codes that are links to full<br />
records.<br />
Basically, this objective is achieved by<br />
adapting existing registration systems<br />
modernization using bar code identification labels<br />
on radio frequencies, scanners and computer<br />
systems, etc..<br />
C. Procedure for withdrawal of products<br />
Ultimately, the realization of a traceability<br />
system which aimed at creating the possibility of<br />
withdrawal of one or more lots of products that<br />
proved it could endanger the safety of consumers.<br />
For this, it is necessary to ensure operability<br />
procedures for the withdrawal of products as part<br />
of the traceability system.<br />
An effective model to provide such a<br />
procedure is provided by the Canadian Food<br />
Inspection Agency. This system includes nine<br />
steps and is implemented in the unit studied.<br />
1. Management team meeting. In the<br />
documentation to withdraw products are specified<br />
identity and how to contact each member of team<br />
management responsibilities in this proceeding and<br />
appointed substitutes. The team includes members<br />
of senior management in departments such as<br />
production, quality management, distribution,<br />
public relations, etc.., Such as operations<br />
managers, lawyers and media experts.<br />
2. Keeping records of complaints<br />
(complaints file). This documentation includes a<br />
formal specification for recording complaints and<br />
noncompliance, so that the nature of complaints to<br />
be recorded with the actions taken by the company<br />
to investigate the causes and prevent recurrence of<br />
such events.<br />
3. Listing of contacts for product recalls.<br />
Information on individuals and organizations to be<br />
contacted in case of withdrawal of a product<br />
should be stored in a file that will be periodically<br />
reviewed and updated as needed. This information<br />
includes:<br />
a. competent authority to be informed, as<br />
required by law, the incident requiring the<br />
withdrawal of a product;<br />
b. customers - to locate product along the<br />
food chain and information that next tier of<br />
channels;<br />
107<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
c. suppliers - for information on any product<br />
that does not conform to specifications, to initiate<br />
appropriate measures;<br />
d. media - if the product was distributed in<br />
the market and will be necessary to inform<br />
consumers about product details and the potential<br />
generated by its use.<br />
4. Tracking and tracing of products based<br />
documents including traceability procedures<br />
implemented by the company.<br />
5. Making records to supply and distribution<br />
records to ensure traceability, the firm should be<br />
able to determine that the product provider and<br />
where raw materials were distributed products<br />
were obtained from the same batch of raw<br />
materials. It also identified the person responsible<br />
for recording these documents.<br />
6. Setting the procedure for withdrawal is<br />
part of this procedure are defined various levels of<br />
response to non-compliance. This can range from<br />
reimbursement or replacement of poor quality<br />
product to withdraw the full amount of product on<br />
the market, if an incident is a serious risk to<br />
consumer health. If withdrawal of a product is<br />
important to set a clear scenario of events covered.<br />
For each sequence there is a written procedure<br />
detailing to be done, how and by whom.<br />
7. Registration withdrawn products. For<br />
reasons of accountability, records are kept of<br />
products withdrawn so as to ensure that all<br />
products have been withdrawn from the food chain<br />
and to measure the effectiveness of the withdrawal<br />
plan. Records include details about the product, the<br />
amount withdrawn, the date of withdrawal and<br />
removal product in the food chain and details on<br />
what to do with the product.<br />
8. Assessing the effectiveness of the<br />
withdrawal procedure. A good management<br />
practice, to achieve the withdrawal procedure,<br />
requires to evaluate and efficiency and<br />
improvement.<br />
9. Testing withdrawal plan if necessary to<br />
withdraw a product is late discovery that the<br />
system fails. It is therefore important that the<br />
withdrawal procedure is tested regularly. This is<br />
part of traceability or verification procedure can be<br />
done regularly.<br />
D. External Traceability<br />
External traceability allows product tracking<br />
throughout the food chain, ie from the raw material<br />
to consumer. To achieve this it is necessary that<br />
information held by an individual company to be<br />
shared and other participants in the food chain.<br />
This exchange of information takes place in<br />
parallel with product movement in the food chain.<br />
Administrative manager responsible for<br />
ensuring the traceability of the unit Ulerom SA, is
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
the person in charge of gathering information from<br />
other participants of traceability.<br />
Development of systems for ensuring<br />
effective external traceability must overcome some<br />
obstacles such as:<br />
• commercial confidentiality because<br />
information about the product is regarded as a<br />
good and companies are reluctant to provide<br />
information about it;<br />
• Identify information required to be<br />
transferred along the food chain - because the<br />
amount of information about a product should be<br />
determined what is necessary to ensure<br />
traceability.<br />
• Compatibility information with individual<br />
internal traceability systems.<br />
• Differences between legal provisions for a<br />
different product markets and therefore in different<br />
countries.<br />
External traceability is achieved by ensuring<br />
traceability systems alone and embedded.<br />
A traceability system is achieved where<br />
independent companies take responsibility for<br />
obtaining the information necessary to trace their<br />
suppliers and their transmission to its customers.<br />
All unit, so Ulerom S.A. both suppliers and<br />
customers realize their traceability systems, taking<br />
into account the information provided by other<br />
units of the chain. This transfer of information<br />
meets the minimum legal requirement of European<br />
legislation. This system is called "closed system".<br />
In such a system, a company with the object of<br />
processing of raw materials supply, ensure that it<br />
provided all information necessary to identify the<br />
supplier and product identification code. Usually,<br />
this means that receives information about the<br />
product as a delivery note with the product label<br />
attached.<br />
E. Verification and certification of<br />
traceability systems<br />
Traceability systems are criticized because<br />
the food chain information is not detailed and<br />
consistent. Therefore, implementation of such<br />
systems involve a high degree of responsibility for<br />
the economic actors involved in the food chain.<br />
We believe that a traceability system is effective<br />
only if the physical and security measures they<br />
prevent fraud. The audits, security systems are<br />
evaluated on the basis of performance and speed of<br />
providing information.<br />
Produce not randomly selected for testing<br />
must be identifiable throughout the production<br />
process for the removal operation to be quick and<br />
efficient.<br />
Traceability systems are checked to see if<br />
they fulfill many purposes such as:<br />
108<br />
• Obtaining evidence of traceability in the<br />
upstream and downstream of the check.<br />
• Establish a clear transparency of<br />
manufacturing production continues.<br />
• Include all materials and ingredients.<br />
• Provide a response within a relatively short<br />
time.<br />
• Provide clear and readable information for<br />
client or customer.<br />
Assessing the effectiveness of a system to<br />
ensure traceability is achieved through auditing,<br />
similar to checking the effectiveness of other<br />
systems, that the quality management, food safety,<br />
work safety and the environment.<br />
Auditing is an action of making an audit,<br />
systematic, independent and documented evidence<br />
of obtaining an objective measure to determine the<br />
extent to which audit criteria are met. The audit is<br />
the main way by which a company can obtain<br />
evidence that the system has implemented or not.<br />
The audit can be achieved by several types:<br />
• Internal Audit (first part) - that made by the<br />
representatives of a company's own needs or<br />
representatives of a unit qualified to perform this<br />
activity.<br />
• second-audit is conducted by customers of<br />
a company or their representatives.<br />
• Audit of tertiary services requires use of<br />
specialized external audit firms, such as<br />
certification companies.<br />
The audit is done in several stages: planning<br />
and preparation of audit, management audit,<br />
analysis results, establish corrective actions,<br />
verification of the corrective actions.<br />
Ensuring traceability systems are regarded<br />
as part of quality assurance management system.<br />
The traceability is considered to interact with<br />
HACCP system, but can be seen as a separate<br />
operating system, mainly related to the control<br />
system. The inspection and certification of food is<br />
based on the same objectives and same effect as<br />
the traceability system. Thus we must consider:<br />
• Inspection consists of examining foods or<br />
food control systems, raw materials, manufacturing<br />
and distribution process, semifinished and finished<br />
products testing for compliance with applicable<br />
standards.<br />
• Certification is the procedure by which the<br />
certification takes the responsibility that food and<br />
food control systems conform to standards.<br />
Certification of food inspection activities based on<br />
the flow, audit quality assurance system and<br />
examination of finished products.<br />
• Equivalence is the capability of different<br />
inspection and certification systems to have the<br />
same objectives.
Minimum information to be included on the<br />
label refers to:<br />
• provider name,<br />
• product description,<br />
• the provider product codes,<br />
• date of manufacture.<br />
Transfer information through a written<br />
record is considered inefficient in some cases<br />
because the information must be entered into the<br />
information system of each company making up its<br />
chain. External traceability system efficiency is<br />
greatly enhanced when information transfer is done<br />
109<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
electronically in a format approved by all<br />
participants and the food chain.<br />
An easy way to solve this potential problem<br />
is the use of standardized bar codes database<br />
company. This involves an integrated approach to<br />
traceability, which can benefit the entire food<br />
chain.<br />
F. Economic efficiency of traceability<br />
Evaluation of economic efficiency through a<br />
system of indicators is a lot of information with<br />
regard to investment activity and production efforts<br />
quantifying the effects and their behavior<br />

The average income in the years 2007-2010<br />
was 115.311 thousand. Revenues are recorded and<br />
they increased in 2007-2009 by about 50.8%, but<br />
the same can be said for the year 2010 when<br />
revenues fell by 9.3%.<br />

In the period 2007-2010 was spent<br />
approximately one thousand four hundred<br />
thousand every year to implement it. Although<br />
implementation of the traceability system costs are<br />
not covered and no profit is made from them, the<br />
advantage of this system will be noticed in time,<br />
when consumers will be informed far more<br />
specific about the route that follows the product<br />
before it is consumed .<br />
Unit Ulerom S.A. achieved profit increases<br />
in all years take into account, less in 2010 when<br />
profit was a decrease of 989.483 thousand the<br />
previous year. Unit profit increased by 59,3%<br />
between 2007-2009. According balance declared<br />
Ulerom S.A. no losses in any year.<br />
After implementation of the traceability both<br />
gross profit and the net income derived unit

suffered declines, which will be recovered in the<br />
near future. In all four years consider profit<br />
decreased on average by 8,25% in 2008-2010. The<br />
largest decrease occurring in the first year the<br />
system was implemented respectively in 2007, the<br />
unit profit decreased by 39.5%.<br />
Labor productivity measures the efficiency<br />
of work in a while.<br />
Average labor productivity is 635 lei /<br />
person, this average was exceeded in 2008-2010,<br />
the most effective productivity in 2009 was<br />
767.000 lei / person exceeds approximately 100%<br />
productivity in 2007 which was only 386.000 lei /<br />
person.<br />
Rate of return - the ability of firms to get the<br />
work they carry out a profit in terms of mobilizing<br />
the resources available. This, before establishing<br />
traceability in all four years taken into account is<br />
1,51% to 1,04% as profit rate after the<br />
implementation of traceability. Differences were<br />
recorded in 2007 and 2010 the rate of profit fell<br />
1,79% to 0,94%, it happened during the tracking<br />
system did not apply.<br />

CONCLUSIONS<br />
Implement system to ensure traceability lead<br />
to improved business entities with control<br />
processes.<br />
Economically, the design and<br />
implementation to ensure traceability economically<br />
not improve results but to reduce the economic<br />
efficiency of this. The case study in S.C. Ulerom<br />
S.A. implementation of this system has reduced<br />
profitability from 1,5% to 1,0%.<br />

SOME ACTUAL ISSUES OF SUSTAINABLE DEVELOPMENT MANAGEMENT<br />
Abstract<br />
Viorel POP 1 , Mircea POP 1<br />
e-mail: leroivpop@yahoo.com<br />
Human society is undergoing a more profound identity crisis period, economic development based on the waste of raw<br />
materials, fuels and energy, contributing greatly to this crisis, having as basis the premises of wrong priorities. In order<br />
to avoid an ecological disaster of proportions, a series of scientific personalities, and most ordinary people - have taken<br />
firm attitude towards the phenomenon of pollution, from which results the deterioration of our living environment. In<br />
these conditions arose the concept of "sustainable development". Management is certainly the main driver of economic<br />
development of the world of the twentieth century, world that increasingly uses scientific knowledge, management<br />
being itself the result of applied scientific knowledge. As a result - the sustainable development also can enjoy the<br />
advantages of using techniques, functions and general approaches of management regarding the overall development<br />
paths, in order to achieve maximum results in the proposed goals, set at the level of local communities, states or even<br />
globally, in terms of reducing material consumption and pollution, to achieve the goal of welfare for all, on a clean<br />
planet.<br />
Key words: sustainable development, global issues, management.<br />
The development without hindrance since<br />
the world entered the "industrial age" now more<br />
than 200 years, has started from the image of<br />
"unlimited" dimensions of our planet and its ability<br />
to ensure "forever" non-renewable mineral<br />
resources, excellent living condition and welfare<br />
for a rapidly expanding population, but also the<br />
planet's ability to take forever pollutants from<br />
industrial and non-industrial activity.<br />
In the world literature numerous papers have<br />
appeared in recent decades, referring to "global<br />
problems" which human civilization faces now, at<br />
the beginning of 21st century. "Problems" are<br />
those who, at the Planet level, essentially influence<br />
all areas of social life, their non-resolving making<br />
impossible to address other problems, which also<br />
require a solution at global-planetary level.<br />
Industrial and agricultural production has<br />
spectacularly increased, based on unprecedented<br />
progress in science and technology, which led to a<br />
deepening global division of labor, expanding<br />
international economic and trade relations,<br />
emphasizing the interdependence of all countries at<br />
worldwide level.<br />
As a consequence of the process<br />
enlargement of industrialization, also increased the<br />
need of raw materials, energy and food,<br />
urbanization spread, reaching the maximum level<br />
of affordability of the planet, due to the limited<br />
mineral resources and the pollution phenomenon<br />
1 University of Agricultural Sciences and Veterinary Medicine of Iasi<br />
which inherent accompany in the current<br />
development conditions of human society. Thus, it<br />
requires more and more an efficient management<br />
of natural resource use (Davidescu D., 2002).<br />
MATERIALS AND METHODS<br />
Data and concepts from the literature were<br />
used as materials and methods, data which were<br />
processed and from which we have determined new<br />
original elements of interest, who came to support the<br />
things presented in the paper.<br />
RESULTS AND DISCUSSIONS<br />
The concept of sustainable development<br />
Lester Brown is credited to be the first to<br />
release – in the World watch Institute report in<br />
1984 - the term "sustainable development" which<br />
then entered in the literature as a reference term<br />
and became the object of all studies and policy<br />
documents that address issues of contemporary<br />
social economic development, expressing the<br />
increasing concerning of global communities<br />
regarding the fact that the current model of the<br />
global economic system is unsustainable in terms<br />
of resource use of the planet and the balance of<br />
environmental factors (Flavin C. 2002).<br />
In the 1984 report, "sustainability" was<br />
defined as the possible development in harmony
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
with nature - as an ecological concept with<br />
economic consequences, pointing out that a<br />
"sustainable society" is the one that shapes / adapts<br />
POPULATION<br />
GROWTH<br />
Gro Harlem Brundtland (woman) Prime<br />
Minister of Norway presented the report entitled<br />
"The future of us all" in the UN Commission on<br />
Sustainable Development (1987). The report<br />
highlights the problem created by the<br />
"demographic explosion", the unbalanced<br />
geographical distribution of population in<br />
connection with the available resources of the<br />
planet and the need of efforts to eliminate poverty,<br />
raising levels of culture and the development of<br />
human capacity to improve the efficient use of<br />
available resources.<br />
Regarding species and ecosystems, it<br />
highlights the need to maintain genetic diversity<br />
and the introduction in this target, in the center of<br />
political programs, the problem of protecting<br />
endangered species and ecosystems, proposing a<br />
protection program of tropical forests and<br />
developing an extensive international cooperation.<br />
In this sense, sustainable development can<br />
be defined as the development that can be<br />
sustained (maintained) in time with the limited<br />
resources we have.<br />
Essential components of a strategy for<br />
sustainable development include:<br />

- Recycling, reducing consumption of<br />
mineral resources.<br />
Regarding the demographical explosion,<br />
according to UN statistics, in October 2011 we<br />
passed the border of 7 billion people, triggering a<br />
new alarm that the world would move towards a<br />
Malthusian crisis, by depletion of natural<br />
resources, mainly drinking water and food crisis,<br />
overall environmental degradation etc.<br />
However we can say that the alarm is<br />
inappropriate, because the growth rate of world<br />
population slows, although the last 3-4 billion<br />
came in an accelerated pace, 1 billion in 12-15<br />
years, see Table 1:<br />
Compared to 1 billion people, the growth<br />
rate of world population declined in the last 60<br />
years from 20.83 million annually, to 13.88<br />
million, which represents a decrease in the<br />
percentage of population growth with 33.36%,<br />
despite increasing life expectancy recorded in this<br />
period.

* population growth, in million inhabitants<br />
In the latest UN projections, the growth rate<br />
of world population will decrease to zero at the<br />
middle of this century. But the greatest challenge<br />
that the world will face in future is aging. It is<br />
known that the developed world is already<br />
experiencing population aging, due to falling birth<br />
rates and rising life expectancy. In the coming<br />
decades this phenomenon will include also<br />
developing countries.<br />
However, increasing to 10 billion people on<br />
our planet will be a very difficult exam to ensure<br />
decent living conditions: food, water, housing etc..<br />
Particulars of sustainable<br />
development management<br />
Management is certainly the main driver of<br />
economic development of the world of the<br />
twentieth century, world that increasingly uses<br />
scientific knowledge, management being itself the<br />
result of applied scientific knowledge.<br />
A number of authors including Richard<br />
Farmer said that "management is one of the key<br />
factors that explain why a given country has<br />
become rich, or remained poor."<br />
The managerial process must begin with a<br />
correct determination of objectives, operating both<br />
with strategic objectives and tactical elements, to<br />
support achievement of the strategy. Depending on<br />
the nature and importance of the set objectives,<br />
arise the other functions.<br />
In defining management usually have to<br />
consider three essential components:<br />
- Setting the correct objectives,<br />
- Selecting methods and tools for achieving<br />
them, and<br />
- Follow to fulfill the purpose of achieving<br />
established performance.<br />
Decisions are made by analyzing the likely<br />
changes in the activity, according to the company<br />
profile, the decision being based on the optimal<br />
choice of the many possible ways. Determination<br />
of the optimal solution, is the key issue of the<br />
decision - after all, all management functions are<br />
subordinated to the same purpose - namely to take<br />
correct decisions.<br />
Table 1<br />
The way this function (decision) is realized<br />
highlights the true value of the manager, through<br />
the qualities that he has: competence, balance,<br />
judgment, courage, moral integrity, foresight etc.<br />
Human resource management, includes all<br />
management decisions and practices that influence<br />
directly people, regarding the sustainable<br />
development of those working in organizations<br />
concerned to improve environmental performance<br />
and for others who, being in the adjacent area, are<br />
affected by lack of economic performance or<br />
environmental conditions etc.<br />
In these conditions, of course that the<br />
sustainable development process can enjoy the<br />
advantages of using techniques, functions and<br />
general approaches of management regarding the<br />
overall development paths, in order to achieve<br />
maximum results in the proposed goals, set at the<br />
level of local communities, states or even globally,<br />
in terms of reducing material consumption and<br />
pollution, to achieve the goal of welfare for all, on<br />
a clean planet.<br />
Management functions<br />
in sustainable development<br />
Planning function - answering the question:<br />
"what do we want and what can be done in the<br />
sustainable development process" - allows us to<br />
result in terms of setting objectives, resources,<br />
means and methods (strategies) necessary to<br />
accomplish the objectives, elaboration of solutions<br />
and determine in advance the future problems<br />
(Burtică M., 2010):<br />
What do we want to realize in the<br />
sustainable development process:<br />
- When establishing the objectives,<br />
participation is based on the occupied position on<br />
the issue addressed, some objectives in the<br />
sustainable development process can be:<br />
- Progresses in eco-technology domain to<br />
eliminate waste of resources,<br />
- Providing decent material and spiritual<br />
living conditions to the whole population,<br />
- Measures taken to give future generations a<br />
natural environment as clean and healthy as<br />
possible etc.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
What can be done, in the<br />
technological conditions that we have:<br />
- Our possibilities give us confidence that in<br />
reasonably time all these goals can be satisfying<br />
achieved, provided that those responsible at all<br />
levels, including global level, to want to achieve<br />
these objectives.<br />
Control<br />
Decision<br />
114<br />
Organizing function - the question: "Who<br />
and how contributes to achieve the objectives of<br />
sustainable development" - means all the<br />
management processes through which the activities<br />
to achieve the best possible conditions of the<br />
anticipated objectives are established and<br />
determined.<br />
Figure 2 Management functions applied in the sustainable development<br />
In order to achieve the objectives, participate<br />
those responsible for enforcement of the programs<br />
decided by those entitled to this end, participation<br />
is based on their position on the issue concerned<br />
(economic unit accused, companies responsible for<br />
implementing the action plan, nongovernmental<br />
organizations, people etc.) implementation<br />
consisting as appropriate:<br />
- Compliance with the legal norms of<br />
environmental protection,<br />
- Completion of the ecological rehabilitation<br />
of degraded areas,<br />
- Use of eco-technologies, avoiding waste,<br />
- Progress in line of alternative resources<br />
exploitation,<br />
- Economic development of states and<br />
backward areas, the strategy of raising the living<br />
standard of population etc.<br />
Also, scientists, NGOs and all population<br />
interested can participate to achieve these<br />
objectives.<br />
Coordination function - representing the<br />
process of dynamic organization, consists of all<br />
activities through which the decisions, of the ones<br />
Planning (goal setting,<br />
predicting and planning)<br />
MANAGEMENT<br />
Communication<br />
Organizing<br />
Human<br />
resources<br />
that are entitled, harmonize, in order to optimize<br />
the sustainable development results.<br />
Coordination function, answering the<br />
question: "how can we maximize the program<br />
effects, by optimizing the activity correlation of the<br />
ones involved..." depends largely on managers<br />
potential to maintain a favorable atmosphere of<br />
communication and collaboration of the ones<br />
involved in the established action regarding the<br />
sustainable development, success being assured by<br />
their knowledge and training.<br />
The need for management coordination<br />
process, mainly results from:<br />
- Dynamic processes involved in sustainable<br />
development<br />
- But also from the complexity and<br />
diversity of stakeholders’ relations, demanding a<br />
permanent operative "feedback", which would<br />
ensure adequate correlation and decision of the<br />
planned activities. Due to the scale and complexity<br />
of processes and to the many factors involved,<br />
coordination imposes the optimization correlation<br />
of actions.<br />
Directing function - as a management<br />
function, it includes all activities that stakeholders
in the process of sustainable development are<br />
motivated and determined to contribute to the<br />
objectives set.<br />
Directing function, answers the question:<br />
"How to motivate stakeholders involved in the<br />
sustainable development process so that their<br />
results to be maximum?"<br />
Stages of decision process, according to the<br />
normative methodology of substantiation and<br />
elaboration of decisions and the complexity of<br />
issues addressed are:<br />
- Identifying and defining problems to solve,<br />
- Developing possible solutions,<br />
- Analysis of proposed solutions and<br />
choosing the most favorable,<br />
- Implementation of the solution,<br />
- Analysis / evaluation of results / outcomes<br />
of the decision taken.<br />
Motivation, involves the correlation of<br />
satisfaction of the own interests of the factors<br />
involved in the sustainable development, with<br />
objectives achieving and tasks set. Motivation can<br />
be of various forms, for example:<br />
- Tax incentives for upgrading outdated<br />
technology,<br />
- Constraints caused by the payment of<br />
pollution charges to reduce emissions,<br />
- The community residents must take a firm<br />
attitude against pollution produced by the<br />
economic incriminated agents,<br />
- Taking a firm attitude by the community<br />
residents against pollution of economic agents<br />
incriminated,<br />
- Or incentives to increase production or for<br />
new investment to advantage the community under<br />
the social aspect of sustainable development etc.<br />
Control function - aims "the results of the<br />
activity included in the sustainable development<br />
program..."<br />
Control is the final link in the chain of<br />
management. Control is important because it leads<br />
to notification of any deviations, the causes that<br />
made them and establish measures to address the<br />
deficiencies, to improve work results.<br />
Control helps all those involved in<br />
sustainable development to recognize distractions<br />
factors in achieving goals, helping them to improve<br />
specific performance.<br />
By highlighting in time the violations of any<br />
kind, premises of possible, prompt and efficient<br />
interventions in order to remedy the deficiencies<br />
are created, keeping the chances for achieving the<br />
objectives originally set.<br />
Starting from the premise of "good faith" of<br />
all those involved in attaining the goals of<br />
sustainable development process, factors entitled to<br />
perform control, have also the role of guiding to<br />
115<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
respect the standards prescribed by law and<br />
improving the performance of those accused of<br />
violating the established rules, this way the<br />
function of guidance and control practically<br />
doubles its effectiveness in achieving sustainable<br />
development process.<br />
Managerial methods<br />
Managerial methods - which can be found<br />
in the process of sustainable development, are<br />
based on the multitude of situations that may occur<br />
in this process.<br />
Management methods and techniques that<br />
can be efficiently used in this process are those that<br />
best fit the characteristics and peculiarities of<br />
sustainable development, namely:<br />
- Management method by objectives,<br />
- Responsible management method of<br />
creating a new product,<br />
- Management method by budgets,<br />
- Management method through participation<br />
etc.<br />
CONCLUSIONS<br />
This paper takes to discussion "the concept<br />
of sustainable development", concept led out of the<br />
major global problems more pressing, bringing in<br />
support of finding solutions, management science,<br />
certainly the main driver of vertiginous economic<br />
development of the present world, a world that<br />
uses more and more scientific knowledge,<br />
management being itself the result of applied<br />
scientific knowledge.<br />
To apply the principles and methods of<br />
management in terms of sustainable development,<br />
it is necessary customizing their fields depending<br />
on the specificity of these activities.<br />
The effectiveness of management functions,<br />
used to support sustainable development programs<br />
to maximize the effects, depends largely on<br />
managers potential to maintain a favorable<br />
atmosphere of communication and collaboration of<br />
those involved, the success being provided by their<br />
knowledge and training.<br />
Thus, to achieve the objectives of<br />
sustainable development, of decided programs ,<br />
can and must participate besides the administration<br />
officials, and scientific personalities, NGOs and all<br />
those interested from the population. Only in this<br />
way, interacting on the wishes of all, working<br />
together we will succeed to develop in conditions<br />
of sustainable development concept requirements .

METHODS OF ASSESSMENT THE CAPITALIZATION OF FARMS WITH<br />
PRODUCTION MEANS AND ANALYSES ON FIELD SURVEY<br />
Mirela Adriana RUSALI 1<br />
e-mail: m.rusali@yahoo.com<br />
The research approaches the identification of factors generating non-farm economic performance in Romanian<br />
agricultural holdings. Based on evidences from field studies on equipping farms with productive capital goods, presents<br />
results obtained by applying a model of computation and analysis for the evaluation of farm capitalization – a<br />
determinant of the economic viability of farms, with sustainable contributions to competitiveness increase in the<br />
agricultural sector. The model allowed the evaluation of the initial and real cost of mechanical means used in the sample<br />
farms owned farms, an estimated replacement value of machinery obtained by calculating the value of depreciation and<br />
the present cost of agricultural machines, representing the average value of net investment and the average quantum by<br />
types of agricultural mechanical equipment and by farms. Clustering method was applied on the statistical indicators<br />
corresponding to the sample farms, according to the considered selection criterion. The article presents the results of<br />
data processing, calculations and analyses that reveal assessments on the studied farms, by regional profile and by<br />
holding’s legal status (legal or natural person).<br />
Key terms: agricultural holdings, productive capital, investment, sustainable development<br />
Imbalances and weaknesses in the external<br />
performance of the agricultural sector ground on<br />
several causes at the micro level (Otiman, 2009).<br />
The paper deals with the study of non-performance<br />
general factors in Romania's economy at farm<br />
level, by analyzing the technical capitalization of<br />
the holdings as, either driver, or restrictive<br />
determinant of competitiveness. On the<br />
quantitative evolution, structure and quality of<br />
productive fixed capital depends to a great extent<br />
the ability to manage and use land resources<br />
properly, and thus, future economic development<br />
of the farm. The article presents the outcome<br />
provided by applying a calculation model to<br />
evaluate farm capitalization, in the limits of the<br />
information provided by field surveys.<br />
MATERIAL AND METHOD<br />
The paper used information from field surveys<br />
based on statistical sample of agricultural holdings<br />
and includes the assessment of farms capitalization<br />
with productive means, by constructing and applying<br />
a complex model of measurement and analysis.<br />
The research exploited the database<br />
information obtained by processing the<br />
questionnaires in selected localities of all statistical<br />
regions of Romania, in 2007-2008 - for the<br />
information homogeneity, 406 questionnaires have<br />
been selected, followed by the selection of the<br />
1 Institute of Agricultural Economics – The Romanian Academy<br />
relevant variables, building and establishing the<br />
needed indicators and their inclusion in worksheets,<br />
by types of machines used in farm property (Rusali,<br />
2009).<br />
A computation model have been designed to<br />
evaluate the updated cost of the mechanical means<br />
of the sample, estimates of their replacement value,<br />
obtained by calculating the depreciation cost and the<br />
present value of machinery represented by the<br />
investment net value. The results reveals evaluations<br />
obtained by aggregating and selecting the<br />
appropriate indicators at regional level of analysis, at<br />
the farm level and by the legal status of the holding,<br />
namely, natural or legal persons.<br />
In order to estimate the production technical<br />
capital, it was necessary to calculate the value of the<br />
mechanical factors used in holdings’ property.<br />
Comparable prices have been obtained through<br />
intermediate operations required to update the prices:<br />
nominal purchase prices have been deflated with the<br />
Consumer Price Index (CPI) for non-food goods,<br />
provided by NIS, at 2009 reference period. The<br />
purchasing prices were expressed in Euros at the<br />
annual exchange rate of the acquisition period,<br />
provided by the central bank, and then adjusted to<br />
current exchange rate. The analyses were provided<br />
with the necessary information by applying the<br />
grouping method of the statistical indicators<br />
corresponding to the sample farms, according to the<br />
considered selection criteria (Rusali, 2010).

The detailed results of the analysis include<br />
the regional distribution of agricultural holdings in<br />
the sample by the tractors’ value, by the types and<br />
classes of power, and the value of trailers, trucks<br />
and off-road cars - the cost of depreciation and net<br />
investment. The column indicating “Thousands<br />
RON/farm” shall mean the amount of the net<br />
investment per farm (agricultural holding). As<br />
indicated by figure 1, there are observed disparities<br />
between agricultural holdings concerning the level<br />
118<br />
of net investment per farm and the number of<br />
tractors endowment of farms, but also a nonuniform<br />
regional distribution relative to the amount<br />
of investment.<br />
At the individual farms, i.e. agricultural<br />
holdings with the natural person status, tractors’<br />
capitalization is far below that of the commercial<br />
farms, i.e. legal entities: on the sample average the<br />
estimates amounted to 7618 RON on the holding,<br />
respectively, towards 68639 RON. The sample<br />
average estimated a net investment in agricultural<br />
tractors amounting to 30163 RON per farm.<br />

evaluations to the soil processing and sowing<br />
machines, describing the regional profile, by the<br />

Figure 1 Regional distribution of the agricultural holdings, by agricultural tractors’ value and by legal status<br />
Detailed results include the regional<br />
distribution of agricultural holdings in the sample<br />
by the value of soil processing and sowing<br />
machines, and types – the cost of depreciation and<br />
net investment and the assessments corresponding<br />
to individual farms and legal entities. As<br />
synthetically presented in tables 4-6, the extremely<br />
low estimated values for the soil processing and<br />
sowing machines shall indicate a major<br />
shortcoming of these machines that work in<br />
aggregate with tractors. There are to be underlined<br />
the gaps between the net investments per holding<br />
and the number of soil processing and sowing<br />
machines used in farm’s property, and also a<br />
certain superiority concerning investment on the<br />
legal person holdings. It was estimated an average<br />
value of these machines of 2098 RON per<br />
individual farm, onto 26104 RON per legal farm.<br />
The sample average was valued at 11041 RON per<br />
agricultural holding.<br />
Tables 7 to 9 contain the results of the<br />
assessments on the fertilizers and chemical<br />
treatment spreading machines, in the regional<br />
profile, at the level of holdings in the sample and<br />
by their legal status. Fertilizing machines and<br />
chemical treatments machines have a similar<br />
situation as regional distribution, but the average<br />
amount per farm of the net investment is<br />
dramatically lower. On these machines, it was<br />
estimated an average value of 1165 RON per<br />
holding with the status of natural person and 4818<br />
RON per legal farm, resulting a sample average of<br />
2514 RON per farm. Detailed results include the<br />

Tables 10, 11 and 12 indicate the results of<br />
evaluations on field survey data regarding the<br />
combines and harvesting machines used in farms’<br />
property, their regional profile, aggregated at farm<br />
level, and by the legal status of the farm.<br />
The average value of net investment per<br />
farm, is evidently much lower on individual farms<br />
than on commercial farms, given the differences in<br />
average physical farm’s size: from 0.3 ha (in R6,<br />
Region North-West) to 56 ha ( in R2, South-East),<br />
per individual farm, and from 66 ha (in R4, South-<br />
West), to 888 ha (in R3, South), per commercial<br />
farms.<br />

The analysis provides results on the regional<br />
distribution of farms in the sample by the value of<br />
combines and harvesters used in farms’ property,<br />
by type - net investment and depreciation costs and<br />
the estimates corresponding to farm’s legal status.<br />
It has been estimated an average value of these<br />
assets of 4414 RON per farm with status of natural<br />
person, and of 45987 RON per legal farm, while<br />
the sample average was estimated to 19773 RON<br />
per farm.<br />
In Tables 13 to 15 are presented results of<br />
assessments to other agricultural machines used in<br />
farms endowment, including fixed and mobile<br />

CONCLUSIONS<br />
The outcome of the analyses indicate the<br />
lack of modernization of agricultural holdings, that<br />
requires massive investments, with a significant<br />
public component, in technical means, including<br />
the agricultural mechanization and the irrigation<br />
systems. The productive capital will facilitate the<br />
restructuring by the development of agricultural<br />
and rural households, giving them opening options<br />
toward agricultural, food and non-agricultural<br />
markets.<br />
The information and data on holdings’<br />
endowment with own means of mechanization the<br />
farming activities have a poor availability in the<br />
published statistics. The lack in data has two main<br />
causes of the national methodology: the structural<br />
surveys in agriculture does not record detailed<br />
specialized data, and the individual farms do not<br />
have accounting system or keep farm budgets.<br />
The harmonized European methodology<br />
RICA requires accounts only for commercial farms<br />
included in the sample surveys, listed in the farm<br />
fiche (EC, 2007).<br />
Sustainable development means long term<br />
non-negative developments; at the rural level as<br />
well, small holdings have an economic, social and<br />

environmental importance, giving them a key role<br />
to ensure the development of regional<br />
competitiveness and sustainability in accordance<br />
with the requirements of eco-conditionality and<br />
social historical specificities of the zones. Within<br />
this context, rural sustainability implies that a<br />
integrating vision of these resistance structures in<br />
order to benefit from the support policies<br />
designated to the rural space, including agriculture.<br />
Further research relays its utility in<br />
identifying the real problems of the agricultural<br />
sustainability related to non-profit generators, with<br />
direct influences on the sector’s performance.<br />
Relevant conclusions and results can be<br />
substantiated by correlation with other indicators,<br />
such as those related to productivity and efficiency,<br />
and by research and analysis on the basis of other<br />
criteria, for example those related to the size of<br />
farms, production or geographic profiles a.s.o..<br />

ZINC - MICROELEMENT OF REFERENCE IN APPLE NUTRITION<br />
Diana Elena BOLOHAN 1 , Mariana VOLF 1<br />
e-mail: bolohandiana@yahoo.com<br />
This paper aims to present the risk of being exposed apple trees to zinc deficiency, within an bifactorial experience<br />
with fertilizers. Mobile Zn content in soil, on one hand and total zinc content in plant material (leaves) on the other<br />
hand, as mobile phosphates content in soil, represents agrochemical indices for assessing the probability of zinc<br />
deficiency. These indices determined during two years of experimentation, can be quantified in two synthetic indicators<br />
IRPM - mobile phosphates reaction index in soil, used for chernozems, that express and explain the influence of pH and<br />
available phosphorus content (P-AL ppm) on Zn mobility in soil and its availability to plants; and ICZn - zinc<br />
deficiency index, which takes into consideration the value of mobile Zn content in soil, being more significant in order<br />
to predict the probability of zinc deficiency appearance. Folowing the fertilization of experimental variants, we<br />
analyzed the data obtained during two consecutive years of experience, and noticed that available phosphorus content in<br />
soil increased gradually, while mobile Zn, although increasing quantity, it lies within suboptimal limits. Together these<br />
values and soil pH, which has the tendency to rise up to 8.00, the two indices calculated ICZn and IRPM, clearly<br />
indicates that the probability of deficiency in zinc appearance is medium to large, ICZn take values between 1.39 and<br />
3.13, while IRPM take values between 0.117 and 0.232.<br />
Key words: apple trees, fertilization, zinc, phosphorus,<br />
Zinc is an important microelement in mineral<br />
nutrition of apple trees, contributing to a normal<br />
growth and development. It plays an important role<br />
in fecundation, impregnating resistance to<br />
pathogens attack and decisively influencing the<br />
quality of the apple crop. Impact of zinc presence<br />
in the plant tissues can be translated as its<br />
implication in biochemical process through its role<br />
in enzyme activity, in photosynthesis, protein<br />
synthesis and not least by ensuring an adequate<br />
stability and permeability of cellular membranes.<br />
Regarding apple culture, there occurs both<br />
the risk of deficiency and toxicity phenomena. It is<br />
known that apple trees are sensitive to zinc<br />
deficiency and less to the toxic effect that occurs<br />
following the uncontrolled treatment for plant<br />
protection with products based on Zn, in disease<br />
control. There are a couple of factors that influence<br />
appearance of zinc deficiency in plants and must<br />
be taken into account: plants susceptibility, soil<br />
conditions, climatic conditions and also<br />
agricultural applied agrotechnics (Budoi, 2000).<br />
Soil, by its physical and chemical attributes,<br />
is the most representative factor in the likelihood<br />
phenomenon of Zn deficiency and may exercise<br />
this attribute, with a value exceeding seven pHH2O<br />
by low content of mobile Zn, the presence of<br />
carbonates, available phosphorus content<br />
1 University of Agricultural Sciences and Veterinary Medicine Iasi<br />
exceeding 50 ppm, a low content of humus, surface<br />
erosion, compaction and also through degradation.<br />
This is why the central objective of research<br />
in this paper is forecasting the occurrence of zinc<br />
deficiency phenomenon, reflected by the<br />
determination and calculation of simple and<br />
synthetic indicators that aim the insurance status of<br />
available phosphorus and mobile zinc in soil. This<br />
makes possible to limit this phenomenon through<br />
agricultural practice - appropriate fertilization.<br />
The obtained results lead to the conclusion<br />
that forecasted zinc nutritional disorders<br />
(deficiency) for apple trees is a prerequisite in the<br />
context of phosphate fertilization, along with<br />
adjusting the ionic composition of the soil and by<br />
maintaining the soil pH in acid to neutral field<br />
(Huang et al., 2000).<br />
MATERIAL AND METHOD<br />
Researches were carried out in „Vasile<br />
Adamachi‖ Farm, Iassy county, in 2010. This study<br />
was conducted over one crop Idared variety apple<br />
trees, in a 4x4m spacing.<br />
Fertilizing treatments were randomised within<br />
one block; groups of three trees; in three replications.<br />
In the experience were studied 9 variants of<br />
fertilization with mineral and foliar fertilizers, including<br />
the blank:

NPK15.15.15 was applied 1/3 in autumn and<br />
2/3 in early spring. Foliar fertilizers (Cropmax and<br />
Pentakep-G) were applied three times, starting when<br />
the fruit was 5 mm in diameter, and every two weeks<br />
after. Soil pH was determined in water through<br />
potentiometric method.<br />
Soil and leaves samples were analysed for:<br />
- P-AL = available phosphorus content in soil,<br />
extracted by the Egner-Riehm-Domingo method, by<br />
spectrophotometry;<br />
124<br />
- Pt% - total phosphorus content in leaves , by<br />
spectrophotometry;<br />
- available Zn content in soil, extracted in<br />
EDTA 0,01 N solution, determined by atomic<br />
absorbtion;<br />
- total Zn content in leaves by atomic<br />
absorbtion.<br />
RESULTS AND DISCUSSIONS<br />
Analyzing obtained data (table 1) there is an<br />
increase of mobile phosphorus content in soil<br />
directly proportional to gradually increased doses<br />
of fertilizers administered on variants, but also<br />
there is an increase from one year to another. In<br />
2010, mobile phosphorus content in soil recorded<br />
48 ppm for unfertilized variant, up to 66 ppm for<br />
N90P90K90+Cropmax variant, that fits soil to a<br />
low state of insurance (36.1 to 72 ppm).<br />

Table 2<br />
values in leaves fall below this threshold, for all<br />
variants of fertilization, that indicates the risk limit
for visible manifestation of deficiencies (12-15<br />
ppm Zn total)<br />
The values presented in table 3 express the<br />
probability of zinc deficiency, for the apple trees,<br />

For 2010 ICZn values are between 1.78 and<br />
3.13, values over the the threshold of 1.70. In<br />
2011, in most variants, ICZn values falls below<br />
this threshold, except Pentakeep – G fertilization<br />
variant, which shows that the probability of zinc<br />
deficiency occurence is appreciable in the first year<br />
and in the second year this issue is much more<br />
accentuated.<br />

For interpretation of zinc deficiency<br />
occurence by IRPM, we remark that values are<br />
below 0.288 for all variants of fertilization, for<br />
both years 2010 and 2011, which shows high<br />
probability of zinc deficiency expression (Borlan,<br />
1994).<br />
Figure 1, 2, 3 and 4 express the values of all<br />
indicators, simple and synthetic, involved in<br />

assessing and predicting the occurrence of zinc<br />
deficiency, namely P-AL (ppm), mobile Zn (ppm),<br />
IRPM and ICZn.<br />
Interpreted by ICZn values, Zn deficiency in<br />
the apple trees is moderate in 2010 and high in<br />
2011, increase proportional with increasing<br />
phosphate in soil for 2011 compared to 2010, for<br />
all variants of fertilization.<br />
Figure 2 Mobile Zn content in soil over 2 years<br />
Figure 4 IRPM absolute values over 2 years<br />
Even if mobile Zn content in soil is normal,<br />
values of plant material analysis indicate a weak<br />
state of suply, which explains a failure in its
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
absorption. This indicator is used when there are<br />
data from foliar diagnostic which can express<br />
much better zinc deficiency risk, even if symptoms<br />
have not occurred yet<br />
Mobile phosphates reaction index (IRPM) is<br />
more general and takes into account only the level<br />
of phosphate content in soil and the pH. From this<br />
point of view, IRPM indicate a high probability of<br />
occurrence of zinc deficiency for both<br />
experimental years, drawing attention especially<br />
the upward trend of mobile phosphorus content in<br />
soil. Although P-AL values in the soil is below<br />
optimum, IRPM is most likely used for soils with<br />
pH that reach values of 8.00.<br />
CONCLUSIONS<br />
Zinc, along with other microelements are<br />
important in plant mineral nutrition, especially for<br />
those with medium and high susceptibility to<br />
deficiency, that disturb a series of biochemical<br />
processes and decisively influence plant growth<br />
and development.<br />
Apple tree is one of the susceptible species<br />
to the occurrence of zinc deficiency, according to<br />
the undertaken study where ICZn and IRPM<br />
126<br />
determined values were below the limit of 1.70,<br />
respectively as 0.218.<br />
The increase of soil phosphate content and<br />
alkaline pH has a negative impact on the zinc<br />
mobility and accessibility, inducing zinc deficiency<br />
initially hidden, detected by foliar analysis, and<br />
then visible deficiency (developing symptoms),<br />
more difficult to control and correct.<br />
In variants fertilized exclusively with foliar<br />
fertilizers, Pentakeep - G and Cropmax, with zinc<br />
besides other nutritive elements, are observed<br />
IRPM and ICZn values significantly higher, which<br />
explains extraroot nutrition as preventing measure<br />
of zinc deficiency.<br />

Crop structure is determined according to market requirements and pedo climatic conditions of the area. Depending on<br />
the optimization criteria, the crops will be optimal when it ensures the achievement of maximum profitability, in terms<br />
of assure quantity and assortment, to meet the requirements of the national economy for agricultural products, the full<br />
use of land and other means of production and also in the conditions of respect the plant culture restrictions regarding<br />
the share in crop rotation. Critical in optimizing the structure of crops is the economic efficiency, and made profits. The<br />
economic efficiency is in continuously changing due to raw materials and production goods changing prices. From here<br />
is the necessity of optimizing the structure of crops in each cycle of agricultural production.The main indicators used in<br />
optimizing the structure of crops are yield per hectare, cost of production to the surface unit, gross profit per hectare, the<br />
unit cost, of costs in 1000 lei income rate of return. Linear programming method presents the great advantage that<br />
allows choosing the optimal structure variant of a multitude of possible variations. Given the large volume of<br />
calculations, the linear programming technique involves mandatory, the use of electronic computing.Optimizing the<br />
structure of crop through linear programming requires drawing up the economic-mathematical model, including<br />
variables, restrictions, the purpose function and free terms.The purpose function can be represented by maximizing the<br />
effectiveness (gross profit or economy expenditure) or minimize the effort (total spending or intermediate<br />
spending).The considered restrictions are: the total area cultivated with cereals, minimum and maximum area occupied<br />
by grains, the average obtained production.The case study was conducted in suburban area of Iaşi, which includes the<br />
following communes: Valea Lupului, Leţcani, Bîrnova, Ungheni, Tomeşti,Victoria, Aroneanu, Rediu, Popricani,<br />
Miroslava, Ciurea, Schitul Duca, Holboca. The average bonity note of arable land is 55 points AETA, which<br />
corresponds to an area favorable for grain culture.<br />
Key words: optimization, linear programming, cereal grains, suburban area<br />
The structure of crops is among the<br />
technologies of production, the main component of<br />
plant culture. By the structure of crops we<br />
understand the share occupied by each culture or<br />
vegetal branch in the total cultivated area.<br />
Structure is optimal when cultures ensures the<br />
obtaining of<br />
maximum yield in terms of quantity and<br />
assortment, to meet the requirements of the<br />
national economy in agricultural products, the full<br />
use of land and other means of production and in<br />
terms of respect the plant culture restrictions of<br />
sequence in time and space of the culture.<br />
The optimal structure of the crops undergoes<br />
changes due to the following influences:<br />
the national economy demands;<br />
the market demand for agricultural products in<br />
general;<br />
the insurance level of the company with the<br />
technical-material base;<br />

MATERIAL AND METHOD<br />
The research has been conducted in the<br />
county of Iasi, in suburban area of Iasi and targeted<br />
the optimizing areas cultivated with cereals, using<br />
linear programming, which shows the great<br />
advantage that allows choosing the optimal variant<br />
structure of a multitude of possible variations. Given<br />
the large volume of calculations, the linear

programming technique, involves mandatory the use<br />
of electronic computing.<br />
Optimizing the structure of crop through linear<br />
programming requires drawing up the economicalmathematical<br />
model, including variables restrictions,<br />
the purpose function and free terms. The purpose<br />
function can be represented by maximizing the<br />
effectiveness (gross profit or economy of expenditure)<br />
or minimize the effort (total spending or intermediate<br />
spending).<br />
The variables of the model for optimizing the<br />
structure of cereal crops in suburban area of Iasi will<br />
be represented by: wheat, barley, oats and corn.<br />
The restrictions taken into account were:<br />
total area cultivated with cereals;<br />
minimum and maximum area occupied by<br />
cereals;<br />
an average yield obtained;<br />
the consumption of man-days;<br />
material costs per hectare.<br />
The optimization criteria are the achievement<br />
of the objectives pursued:<br />
the maximization of profits;<br />
the minimization of costs.<br />

CONCLUSIONS<br />
In suburban area (V0), at present time, the<br />
area cultivated with cereals is 17473 ha. The total<br />
costs are up to 40,3 million lei and gross profit<br />
was 6,97 million lei.<br />
In V1 with the purpose function to<br />
maximize the total gross profits, total costs were<br />
lower with 0,25 million and gross profit is higher<br />
with 0,61 million.<br />
In V2, which were aimed the minimizing of<br />
the total costs of production, had been registered a<br />
reduction of 0,19 mil, with a gross profit of<br />
12,931,000 lei (+ 186%).<br />
Of the two types of optimization can be<br />
recommend the first variant, because, can be<br />
realize a higher profits comparing V0 with V2.<br />

Improving the environmental quality by creating green spaces is a key factor in the development of populated areas by<br />
positive general impression and benefits of aesthetic, social, economic and public health nature in the intervention areas.<br />
This study analyzed the effects of "The national program to improve the environmental quality by creating green<br />
spaces in cities" aiming at the staged, controlled and prioritized development of green spaces to achieve the objectives<br />
of Romania under the accession to the European Union and to undertake the obligations under the Community<br />
Environmental Policy. Thus, in Romania through the implementation of this program, the national efforts have<br />
increased both administratively and economically and socially as regards the programming, design and execution of<br />
green spaces in cities, both as new sites, and as the rehabilitation or expansion of the existing ones.<br />
Key words: environment, planning, landscape, spaces, green, parks<br />
The improvement of the environmental<br />
quality should be treated as a quantitative and<br />
qualitative development factor of the populated<br />
areas both administratively and socially, aiming at<br />
the urbanization and access to the recreational and<br />
aesthetic factors of the population in cities (Konga,<br />
et al., 2010). The programming, design and<br />
execution of green spaces are directly dependent<br />
processes of the environmental factors, social<br />
factors and economic factors in the areas of<br />
application, and the objective and systematic<br />
analysis of these factors leads to high diversity and<br />
wealth of the population in those areas.<br />
The literature defines the green spaces as<br />
those areas of land systematized and arranged in<br />
terms of landscape, covered with vegetation and<br />
which usually refer to parks, public gardens,<br />
squares, football courts, golf courts, private<br />
gardens, Botanical Gardens (P.H. Gobster, 2011;<br />
Caspersen O.H., et al., 2006). These spaces can be<br />
opened both to the public use and only selectively<br />
to certain types of users such as the privately<br />
owned green spaces, inside of which one can<br />
access only with the acceptance of the owner (AF<br />
Iliescu, 3003).<br />
"The program to improve the environmental<br />
quality by creating green spaces in cities"<br />
hereinafter referred to as "The Program" aims at<br />
developing the green space infrastructure whose<br />
use is directed exclusively to the general public<br />
and their use must be open to all people who want<br />
to benefit of a positive ambient.<br />
The public green spaces created by the<br />
"Program" are built on the principle of their multifunctionality<br />
and use (Mitchell R. et al., 2008, and<br />
Schilling J., 2010) diversely for the recreational<br />
activities (Vijai Shanker, et al. 2010), of which all<br />
citizens present in a particular area can fully<br />
benefit whether they are residents or visitors in<br />
those areas (Olga Barbosa et al., 2007).<br />
The arrangement of green spaces constitutes<br />
a major and indispensable chapter in the evolution<br />
of urban and rural development at both global and<br />
European (Chiriac D., et al., 2009, James P., et al.,<br />
2009) and national level for Romania, as a longterm<br />
national strategy to improve the<br />
environmental quality in the populated areas by the<br />
systematic elimination of stress elements (Mrkajic<br />
V. et al., 2010).<br />
"The Program" aims at the staged, controlled<br />
(Ianos I., et al., 2009) and prioritized development
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
of green spaces to achieve the objectives of<br />
Romania under the accession to the European<br />
Union and to undertake the obligations under the<br />
European Union Environmental Policy. In<br />
Romania "The Program" is legally supported by<br />
the Emergency Ordinance no. 59 as of June 20,<br />
2007 and Law no. 49 as of March 19, 2008 on its<br />
amendment.<br />
MATERIALS AND METHODS<br />
According to a study made by Richard A.<br />
Fuller and Kevin J. Gaston published in 2009 in<br />
Biology Letters and represented graphically in Figure<br />
1 in 2001 about 170,6 million people, almost 34% of<br />
the European Union population, lived in urban areas<br />
of the European Union and the average green<br />
surface rose to 18.6% of the urban surface.<br />
The colour points representing cities are<br />
coloured according to the proportional coverage of<br />
urban green space within the city. The Country-<br />
According to a release as of October 15, 2007<br />
of the Minister of Environment and Sustainable<br />
Development, currently Minister of Environment and<br />
Forests, the green space standard of 26 sqm/capita is<br />
the minimum value accepted in the European Union<br />
when the World Health Organization recommends an<br />
area of 52 sqm/capita and the European capitals<br />
such as Stockholm and London have at this moment<br />
surfaces of 83 and 64 sqm/capita while in 2007<br />
Bucharest had only surfaces of 9.08 sqm / capita and<br />
that according to data provided by the National<br />
Environmental Protection Agency in 2008 it increased<br />
132<br />
related areas are coloured depending on the<br />
coverage of green space per capita compared to the<br />
urban areas. The grey-shaded areas belong to the<br />
states with data unavailable to the countries whose<br />
data are being collected (Fuller and Gaston, 2001).<br />
At national level, according to the 2009<br />
Romanian Statistical Yearbook, as shown in Figure 2,<br />
in 2008 in Romania there were 9.73 sqm green<br />
spaces per capita in the cities and the total public<br />
green space rose to 21,124 ha.<br />
"The Program" selectively encourages both<br />
quantitatively and qualitatively the national network<br />
infrastructure of green spaces in cities (Ioja C.I. et al.,<br />
2009; Ioja C.I. et al., 2010), being mainly favoured<br />
especially those investments in newly created spaces<br />
and then the extensions and refurbishments of the<br />
existing spaces (Patroescu M., et al., 2004).<br />
In this regard, it aims to increase the area of<br />
green space per capita in the built-up area of cities<br />
and the target at the national level is to exceed 26<br />
square meters of green space per capita by<br />
December 31, 2013.<br />
Figure 1. Green spaces in urban areas in Europe in 2001<br />
to 12.39 sqm/capita (source:www.mmediu.ro,<br />
www.anpm.ro).<br />
So, in the spirit of harmonizing the national<br />
legislation with the acquis communautaire by the<br />
Emergency Ordinance no. 114/2007 on the<br />
environmental protection, "the local authorities are<br />
required to ensure of the built-up land an area of<br />
green space of 20 sqm/inhabitant, until December 31,<br />
2010 (which it wasn’t fulfilled up to the moment) and<br />
minimum 26 sqm/inhabitant, until December 31,<br />
2013" (source: www.cdep.ro).

Realizing the negative effects of the increased<br />
degradation of the quality and quantity of green areas<br />
in Romania at national level, the Romanian<br />
Government issued on June 20, 2007 the Emergency<br />
Ordinance no. 59 whereby a "program" was set at<br />
national level in the populated areas. Thus, at the<br />
European level, those realities have been found since<br />
the end of last century once with the conclusion of the<br />
fifth Environmental Action Programme "Towards<br />
Sustainability" as of on December 31, 2000 and,<br />
therefore, in 2002 by the Decision 1600/2002/EC of<br />
the European Parliament and Council, a new<br />
Community Action Program, aiming both to prevent<br />
the negative environmental effects as a result of the<br />
social factors and industrialization, and the reclaiming<br />
and continuous improvement based on legislative<br />
principles and population awareness was established.<br />
According to the general objectives of the<br />
European Community concerning the environmental<br />
priorities on the climate change control, directions for<br />
nature and biodiversity, environmental improvements,<br />
population health and quality of life, responsible<br />
management of natural resources and waste,<br />
Romania has financially supported and confirmed the<br />
European Environmental Policy by the Emergency<br />
Ordinance 59/2007. These mandatory efforts<br />
undertaken by the accession treaty have as general<br />
objectives the accession of our country to the acquis<br />
communautaire in terms of EU Environmental Policy.<br />
"The Program" was developed over a period of<br />
three years from 2007 to 2010, with the possibility of<br />
extension, and the funds allocated from the<br />
Environment Fund aim at the financially support of<br />
the "Program’s" Beneficiaries, the local authorities:<br />
mayors and county councils.<br />
The Government project was also supported<br />
by the legislative body of Romania by the Law<br />
49/2008 whereby the amount of financeable projects<br />
was supplemented in 2007 by the Environmental<br />
Fund with the amount of lei 15 million, which is<br />
gratifying as regards the legislative support of policy<br />
on the increase of quality of life by creating green<br />
spaces in cities.<br />
Although the law has changed regarding the<br />
content of the "Program" Financing Guide approved<br />
by the Order of the Minister of Environment and<br />
Sustainable Development no. 1166/2007 and<br />
amended by Order No. 1107 as of August 20, 2009<br />
for approval of the "Program" Financing Guide, the<br />
law generally followed the same objectives, namely to<br />
encourage the investments carried out by the<br />
Beneficiaries of this program namely the local<br />
authorities.<br />
During 2007 - 2011 by "The Program", 667<br />
projects with a total value of lei 455,922,629 were<br />
selected and approved by 6 Government Decisions<br />
as a result of four sessions for submission of projects:<br />
• In 2007, according to Decision no. 1256 as of<br />
October 17, 2007, in the session of July 27 to<br />
August 15, 2007, a total of 102 projects with a<br />
value of 58,713,055 were selected (source<br />
www.afm.ro).<br />
• In 2008, according to Decision no. 482 as of May 7,<br />
2008, in the session of January 3-31, 2008 a total<br />
of 97 projects with a total value of lei 59,992,056.55<br />
were selected (source www.afm.ro).<br />
• In 2009 according to Decision no. 1588 as of<br />
December 16, 2009 and after two sessions of<br />
submission, the session as of January 3-31, 2008<br />
and August 25 to September 5, 2008, 35,<br />
respectively 148 projects with a total of lei<br />
122,669,355.04 were selected (source<br />
www.afm.ro).<br />
• In 2010 according to Decision no. 626 as of June<br />
30, 2010 the amounts related to the submitted<br />
projects approved by Decision no. 1588 as of<br />
December 16, 2009, were ratified in sessions as of<br />
January 3-31, 2008 and August 25 to September 5,<br />
2008, where a total of 35, respectively 148 projects<br />
were corrected and approved but with a total value<br />
of lei 123,283,498.68. The difference of lei<br />
614,143.64 compared to the GO 1588/2009<br />
consisting of the introduction and removal of<br />
various expenses considered eligible and ineligible<br />
- "The Program" (source: www.afm.ro).<br />
• In 2010 according to the Decision no. 110 as of<br />
February 9, 2011, as a result of the session as of<br />
September 21, 2009 - October 12, 2009 a total of<br />
285 projects with a total value of lei 214.548.162<br />
were selected (source: www.afm.ro).<br />
According to Order no. 1107 as of August 20,<br />
2009, between the size of the green space created by<br />
"The Program" and the number of inhabitants of the<br />
administrative units, there must be a close bondage.<br />
As seen in Table 1, the funds allocated for the<br />
development of green spaces networks are directly<br />
proportional to the size of cities and type of<br />
arrangements.

The amounts allocated depending on the<br />
projects’ location were thus designed to encourage<br />
the growth of green space per capita in poor areas,<br />
giving priority to those locations where it is necessary<br />
to increase this report. The given score is consistent<br />
with that presented in Table 2.<br />

The quality and type of components is also an<br />
important factor in project selection financed by "The<br />
Program", giving priority to those projects that provide<br />
the majority investments in plants and organic<br />
products, and provided with facilities for irrigation with<br />
sprinklers and lighting panels with photovoltaic poles.<br />
RESULTS AND DISCUSSION<br />
The green spaces are considered by experts<br />
in sociology, health (Maas J. et al., 2006),<br />
economics, culture, education, as real energy tanks<br />
in the standard of living and environmental quality<br />
development and growth mechanism (Ioja C. et al.<br />
2011).<br />
According to the study "Recreational Values<br />
of Public Parks" (Robert Manning & Thomas<br />
More) the users’ interest in parks can be gradually<br />
seen by the many positive effects that they offer.<br />
These are proportional in Table 3.<br />
In this respect, the multi-functionality means<br />
that the newly created, extended or refurbished<br />
green spaces should offer a variety of public utility<br />
services such as recreational activities, social<br />
activities, educational, cultural activities and all of<br />
them according to the specifics and needs of these<br />
areas (Byrne and Neil Sipe, 2010).<br />
134<br />
The variety intends that on the area of green<br />
spaces a large number of useful components are<br />
grouped functionally and recreational, components<br />
which are applied to all potential users and<br />
beneficiaries thereof (Clark P. and Jauhiainen J.S.,<br />
2006).<br />
In this regard, the programming, design and<br />
execution of green spaces should take into account<br />
all components of a recreational space such as: a<br />
diversified vegetation with lawns, paths and access<br />
roads, lighting, irrigation systems, information<br />
elements, urban furniture, leisure furniture,<br />
playgrounds, outdoor fitness equipment, space and<br />
users protection elements, fauna elements and<br />
aquatic ecosystems, fountains, drinking fountains,<br />
lakes, garbage collection areas, sports grounds, and<br />
any other useful items in the administrative areas<br />
and those available to the public (Fanhua Kong et<br />
al., 2010; Ziyu T. et al., 2011).<br />
The arrangement of green spaces should<br />
encourage all recreational activities with<br />
appropriate spaces for walking; resting in nature,<br />
sports, play grounds, social spaces but also<br />
economic activities by the existence of terraces,<br />
restaurants, bicycles renting spaces, boats whereby<br />
the landscape arrangements can make that space<br />
more valuable. An important factor of quality and<br />
durability of the landscape works is their<br />
equipment with irrigation systems smartly and<br />
cost-effective designed so that they can be<br />
exploited later responsibly and economically<br />
(Zazueta F.S. et al., 1995).<br />
By the statistical data analysis and<br />
processing, we, the authors, have observed that the<br />
largest investments in green spaces achieved by the<br />
program have been made in Calarasi, Neamt,<br />
Bihor, Mures, Constanta counties, and the least<br />
significant investments were made in Mehedinti,<br />
Caras-Severin, Valcea, Alba and Ialomita counties<br />
as presented in Table 4 and Figure 3.

Figure 3 The total value of investment in green spaces in funded counties during 2007-2011 by "The Program"<br />
By analyzing the obtained data with the<br />
demographic ones it can be noticed that the report<br />
is relatively disproportionate by the fact that 47%<br />
of the Romanian population lives in rural areas and<br />
53% in urban areas.<br />
Following the analysis at the level of<br />
geographical developing regions, results<br />
summarized in Table 5 and Figure 5, we can see<br />
that Region 3 South is the area where most funds<br />
were absorbed, most of these funds being<br />
concentrated in Calarasi, Giurgiu and Prahova<br />
counties.<br />
Table 4<br />
The lowest investments in relation to the<br />
number of inhabitants and surface were conducted<br />
in South-West Region 4, where the counties of this<br />
region have attracted only 6.19% of the total<br />
available funds.<br />
By analyzing the data presented in Table 6,<br />
it is also observed at county level that Mehedinti<br />
and Caras Severin have attracted the least funds in<br />
creating green spaces, while Calarasi, Neamt and<br />
Bihor counties have applied more aggressive<br />
county policies for the creation of green spaces,<br />

CONCLUSIONS<br />
The performed studies confirm that the<br />
"Environmental quality improving program by<br />
creating green spaces in cities" through its<br />
nationwide implementation has largely met the<br />
overall objective to increase the area of green<br />
space available per capita in cities, but it should be<br />
noted that this increase has resulted in at an uneven<br />
national level, with significant differences between<br />
the values of funds absorbed by the administrative<br />
units in different regions and counties or<br />
administrative organization.<br />
At the same time, we need to emphasize that<br />
at the political and governmental decision level,<br />
they should be implemented with the release of<br />
collateral measure programs that can support the<br />
potential Beneficiaries and provide them the<br />
capacity to attract funds uniformly and equitably at<br />
national level.<br />

THE IMPACT OF TECHNOLOGICAL INNOVATIONS<br />
IN THE FIELD OF INFORMATION AND COMMUNICATION<br />
TECHNOLOGIES ON THE ENVIRONMENT<br />
1 Alexandru-Ioan Cuza University, Iasi<br />
Laura-Diana RADU 1<br />
e-mail: glaura@uaic.ro<br />
The social and economic evolution of the last decades has led to the general use of information and communication<br />
technologies (ICT) with direct and indirect impact on environment. The current trend is to focus on the development of<br />
less invasive hardware for environment and software that should support the monitoring and protection activities of the<br />
human ecosystem. Beyond the amazing facilities provided by the technological innovations, the users’ behaviour should<br />
be rational and by means of individual and collective measures, it should result in positive medium- and long-term<br />
actions, so that the following generations might benefit from life standards at least decent from this perspective. The<br />
technological “explosion” in the ICT field should be used both for the improvement of life standards and for favourable<br />
actions on the environment, the more so as the specific achievements may be the key to solve these problems. This<br />
paper aims to identify the main influences of the innovations in the field of information and communication<br />
technologies upon environment, the way in which they could be used in pro-environment measures and to state<br />
recommendations in view of mitigating the negative effects of these technologies on the human ecosystem.<br />
Key words: information and communication technologies, technological innovation, environment<br />
The information and communication technologies<br />
(ICT) have evolved very much in the last decades,<br />
influencing directly and indirectly all fields of the<br />
activity. In less than half of a century, mankind has<br />
become addicted to them. Their omnipresence<br />
under various forms, mobile phones, PDAs,<br />
notebooks, traffic and electricity control systems,<br />
media communication, etc, all connected to the<br />
Internet, have changed the way people live and<br />
work and have led to the creation of new products<br />
and services, such as employment opportunities,<br />
hard to be imagined before the ICT development.<br />
Nowadays, it is difficult to imagine for a large part<br />
of the population life without various equipment<br />
and specific applications. This spectacular<br />
evolution and the major influence they have at<br />
economic and social level have made ICT to be<br />
considered our collective nervous system— a<br />
platform for helping to solve some of our greatest<br />
economic, social and environmental challenges.<br />
(World Economic Forum, 2009). Their<br />
contribution to the economic growth has been the<br />
topic of numerous studies and the general<br />
conclusion has been that ICT determined the<br />
acceleration of economic development in all fields<br />
and countries, with larger influences in the<br />
developed ones and smaller in the developing<br />
countries.<br />
From the perspective of the economic<br />
theory, there are three factors causing the<br />
productivity growth, through the use of ICT: (1)<br />
the use of more performing equipment, (2) the<br />
increase in work quality considerably influenced<br />
by the easy access to information and knowledge<br />
and (3) the technological innovation manifested in<br />
the creation, distribution and use of new<br />
knowledge (Kozma, B., R., 2008) Currently, the<br />
world is hyper connected by means of the Internet<br />
and other ICT. This phenomenon triggers chain<br />
reaction of progress or downturn, leading to the<br />
disappearance of certain areas and activities and to<br />
the creation of others as a result of technological<br />
innovation. One of the most significant merits of<br />
technological innovation is represented by the<br />
disappearance of geographical barriers, enabling<br />
globalization and the almost unlimited access to<br />
information and knowledge. These represent<br />
premises and consequences of the technological<br />
innovation which, directly or indirectly,<br />
contributes to the economic and social progress. As<br />
far as environment is concerned, the ICT influence<br />
is complex and bidirectional. The dramatic<br />
evolution of the computational power offers
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
exceptional facilities for collecting and processing<br />
of information that strongly exceed the individuals’<br />
ability, in time intervals much superior to the<br />
human life and being able to comprise the entire<br />
earth system from the bottom of the oceans to the<br />
highest atmosphere layers (ITU, 2008). The<br />
estimation of human activity effects and climate<br />
changes they determine can be performed<br />
nowadays with an acceptable precision, by means<br />
of interconnected computational platforms and by<br />
the access to the information stored in high<br />
capacity data warehouses. On the other hand, the<br />
production and use of ICT imply the use of nonreusable<br />
resources, causing pollution, while the<br />
decommissioning of equipment generates large<br />
quantities of non-biodegradable waste. The efforts<br />
made in the last decades focus on finding and<br />
applying solutions in this field in order to<br />
maximize the advantages of ICT use and to<br />
minimize the negative effects on the human<br />
ecosystem.<br />
MATERIALS AND METHODS<br />
The research was conducted by observing and<br />
analysing the main contributions of technological<br />
innovation within the ICT to the economic and social<br />
evolution with direct and indirect influences on the<br />
human ecosystem. The ICT study on environment is<br />
a relatively new preoccupation, their negative effects<br />
being much outstripped by the favourable results of<br />
their use in economy and social life. In comparison<br />
with other fields of activity, where the amount of<br />
waste, energy generated and non-reusable resources<br />
used or air pollution are at very high peaks, the<br />
outcomes of ICT production and use are, apparently,<br />
rather small. The spectacular evolution in the field,<br />
bringing about considerable decrease in prices and<br />
easy access to technology, has determined a<br />
substantial growth of negative, direct or indirect<br />
effects and has drawn the attention of authorities and<br />
public towards environment-friendly ICT. The<br />
developers have also reached a degree of evolution<br />
which allowed them the allocation of considerable<br />
human, financial and material resources for the<br />
analysis of side effects of ICT development and use<br />
and the search for alternative solutions. In this<br />
respect, the developers are interested in finding the<br />
least invasive production methods, inclusively in<br />
terms of used raw materials and stimulation of<br />
product development which should support the<br />
environmental protection activities.<br />
RESULTS AND DISCUSSION<br />
The ICT interfere in the environment by<br />
means of their two forms of existence: hardware<br />
and software. While the negative influence of<br />
hardware components is direct and obvious<br />
(energy consumption, resources used for their<br />
production, waste, pollution), in terms of<br />
142<br />
applications the negative effects are indirect and<br />
the positive ones are multiple and direct.<br />
In our opinion, the ICT negative effects<br />
which are fairly conclusive are translated in the<br />
following results:<br />
o The global information and communications<br />
technology (ICT) industry accounts for<br />
approximately 2 percent of global carbon<br />
dioxide (CO2) emissions, a figure equivalent to<br />
aviation. (Gartner, 2007);<br />
o 18% of office workers never switch off their PC<br />
at night or weekends, and a further 13% leave it<br />
on some nights each week, producing about<br />
700,000 tons of CO2 emissions (equivalent to<br />
the annual emissions of a typical gas-fired power<br />
station) (World Economic Forum, 2009);<br />
o With the fast growth of ICT application in<br />
business operation and people’s daily life, that<br />
energy use by these devices will double by 2022<br />
and increase threefold by 2030 (International<br />
Energy Agency, 2009);<br />
o A photocopier left on overnight uses enough<br />
energy to produce over 1500 copies. (NCB,<br />
2011);<br />
o The total footprint of the ICT sector – including<br />
personal computers (PCs) and peripherals,<br />
telecoms networks and devices and data centres<br />
– was estimated at 830 MtCO2e, about 2% of<br />
the estimated total emissions from human<br />
activity in 2007. Even if the efficient technology<br />
developments are implemented, this figure<br />
seems to grow at 6% each year until 2020. The<br />
carbon generated from materials and<br />
manufacture is about one quarter of the overall<br />
ICT footprint, the rest coming from its use. It<br />
was also estimated that ICT has the potential to<br />
reduce global emissions by 15% by 2020.<br />
(SMART 2020 Report, 2008);<br />
o The cost of running data centre facilities is rising<br />
by as much as 20% a year, far outpacing overall<br />
IT spending, which is increasing at a rate of 6%<br />
(World Economic Forum Green Technology<br />
2009 Report);<br />
o A data centre with 1000 servers uses enough<br />
electricity in a single month to power 16,800<br />
homes for a year. (Forrester Research, 2009);<br />
o At least 240 kilograms of fossil fuels, 22<br />
kilograms of chemicals and 1,500 kilograms of<br />
water are required to produce one desktop<br />
computer. (The ITAM Review, 2012);<br />
o Only 20 percent of total energy use goes into<br />
running a computer; the rest is in its<br />
manufacture. (Williams, E., 2003).<br />
As it can be noticed, the negative incidence<br />
on environment is mainly determined by the<br />
hardware components, while the favourable results<br />
are generated by the use of software whose
functioning is impossible without the adequate<br />
devices. In its turn, this last one may be used either<br />
directly for environment matters, either for the<br />
economic and social activity from various fields,<br />

Nowadays, the economic growth allows the<br />
allocation of resources and interest in the<br />
development of products and production methods<br />
able to generate as little damage as possible to the<br />
human ecosystem. The companies are interested in<br />
the reduced consumption of raw materials, in the<br />
reduction of expenses by means of virtual<br />
activities, or replacement of some tangible goods<br />
with some intangible ones. The innovations in the<br />
ICT field have an important role in this respect<br />
since they allow the development and<br />
implementation of some alternative production<br />
methods and products, the performance of<br />
simulations in order to determine the effects on<br />
environment, the easier and quicker dissemination<br />
towards partners and other interested users.<br />

Change of lifestyle by becoming<br />
aware of environment and education<br />
problems<br />
The technological innovation in the ICT<br />
field is strongly oriented towards the development<br />
of devices and applications enabling the<br />
environment monitoring and finding solutions for<br />
the existing problems, generated either by man or<br />
by natural phenomena. In table 1 we present some<br />
of the ways in which the ICT devices and<br />
applications are used for the efficient management<br />
of the relationship between man and environment.<br />
The degree of ICT use is different, mainly<br />
according to the economic level of each region and<br />
country. The interest in their use is also various in<br />
terms of environmental protection measures. In the<br />
present, after an explosive evolution period in the<br />
production and entrance in the economic and social<br />
life of specific ICT equipment and applications,<br />
after the buzz specific to the pioneering period, a
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
rational and balanced approach is needed where<br />
the attention should move from the super-<br />
144<br />
demonstrated beneficial economic effects, to the<br />
social effects also reflected in environment.<br />
Table 1<br />
ICT for the efficient management of the relationship with the environment (adaptation after ITU, 2008)<br />
The use of hardware and software components for environmental matters can be performed as follows:<br />
Hardware: Software:<br />
Satellite and direct sensor technology that provide the<br />
ability to record and store massive amounts of<br />
geographical and historical information with increasing<br />
resolution and geographic coverage.<br />
Increasingly faster and available microprocessors<br />
which have provided computational power as well as<br />
increasingly intelligent algorithms that have allowed<br />
modeling of environmental systems and thus a better<br />

o Impact and mitigating effects of ICT utilization:<br />
ICT use can mitigate environmental impact<br />
directly by increasing process efficiency and as a<br />
result of dematerialization also and indirectly by<br />
virtue of the secondary and tertiary effects<br />
resulting from ICT use on human activities which<br />
in turn reduce the impact of humans on the<br />
environment.<br />
discourage the sometimes less responsible actions<br />
of producers and users. The organisational,
national and international strategies, applied to<br />
ICT, should mitigate the impact on environment by<br />
encouraging the following actions and behaviours<br />
(ITU, 2008):<br />
o Travel replacement using technologies such as<br />
videoconferencing and audio-conferencing,<br />
tele-education, tele-medicine, tele-care/remote<br />
assistance services, flexi-work, intelligent<br />
living: flexible car ownership, e-Commerce, e-<br />
Government and e-Business in general;<br />
o Reducing energy and material consumption:<br />
o Intelligent building design;<br />
o Intelligent building management<br />
including controlling the internal<br />
environment (heating and air or<br />
climate conditioning) of buildings<br />
through the use of intelligent building<br />
system (IBS);<br />
o e-Commerce, e-Government and e-<br />
Business in general which enhance<br />
process efficiency;<br />
o De-materialization: virtual answering<br />
machines, online billing, web-taxation, video<br />
on demand, music on demand;<br />
o Virtual meetings that could reduce CO2<br />
emissions by around 24 million tonnes / year.<br />
This would include audio and visual<br />
conferencing applications in lieu of travel.<br />
CONCLUSIONS<br />
The interest in the environment-friendly ICT<br />
and in those serving the studies in this field is<br />
increasing. In the last years, the concept of green<br />
ICT has become popular, aiming to reduce the<br />
energy consumption and CO2 emissions by using<br />
ICT and mitigating the impact generated by the<br />
waste resulted from the products specific to this<br />
field. In spite of this, we are still in an expansion<br />
period, and the attempts to reduce the negative<br />
effects are considerable, but still in the process of<br />
being identified and implemented. The advantage<br />
of the current period is that the measures to<br />
counterbalance the negative effects spread with the<br />
same speed as the performances in this area. The<br />
disadvantage is that they have a more reduced<br />
economic and social impact, because they are less<br />
spectacular in comparison with the technological<br />
progress and the facilities offered by the new<br />
technologies to the end user.<br />
In the present context, the position of<br />
national and international organisations as well as<br />
the social awareness is very important. The first<br />
ones may interfere by setting measures that should<br />
stop the development of products harmful for the<br />
environment or offer incentives, under various<br />
forms, while the population, through common or<br />
145<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
individual attitudes and actions, may regulate the<br />
offer through demand. The development level of<br />
each country and region is also decisive in this<br />
field.<br />
Taking into consideration the aspects<br />
presented in the paper, we find useful to set some<br />
recommendations in order to mitigate the direct<br />
negative effects on the environment, applicable for<br />
ICT producers and/or users:<br />
The efficient management of equipment and<br />
the integration, whether it is possible, of<br />
recyclable or biodegradable components;<br />
The promotion of recycling by the<br />
establishment of specialised collection centres<br />
and the education of population in this<br />
direction;<br />
Offering less invasive alternatives for<br />
environment, such as the online<br />
communication instead of travels, the ecommerce<br />
and e-business, the promotion of<br />
experiences and training in the virtual<br />
environment;<br />
The promotion of introduction of<br />
environmental protection measures towards the<br />
equipment producers which should stimulate<br />
the reduction in the use of non-reusable<br />
resources, the pollution reduction generated by<br />
the use of devices and energy consumption;<br />
The reuse of equipment by distributing them to<br />
the interested persons and companies, the<br />
stimulation and encouragement of transactions<br />
from this category in the electronic<br />
environment, leading to the increase in product<br />
lifespan.<br />

THE STUDIES ON THE DYNAMICS CONTENT OF NITRATES<br />
AND NITRITES FROM TOMATOES AND PRODUCTS RESULTING<br />
FROM TECHNOLOGICAL FLOW OF OBTAINING TOMATO JUICE<br />
Corina ANDREI, Dumitru BECEANU 1<br />

The purpose of this study was to monitor the level of nitrates and nitrites in raw tomatoes for industrialization in the<br />
S.C. Contec FOODS S.R.L.Tecuci. The analyses carried out to assess the dynamics of the level of nitrates and nitrites in<br />
the raw material, the technological flow samples and finished product.<br />
Concentrations of nitrates and nitrites have been quantified by molecular absorption spectrometry method. The level of<br />
nitrates tomatoes varied between 7.14-8.11 mg/kg and in tomato juice between 5.04-5.27 mg/kg, these values are under<br />
safety limit set by legislation. The level of nitrites in all cases (tomatoes, chopped tomatoes thermal treated, residue of<br />
skin and seed, tomato juice) are less than 1 mg/kg. The highest concentrations of nitrates and nitrites after processing<br />
tomatoes have been found in the skin and seed, obtained as residue from the processing of tomatoes.<br />
The values obtained were below the maximum permissible concentrations of legislation in force.<br />
Key words: (nitrates, nitrites, tomato, tomato juice)<br />
In recent years, an increasing interest<br />
concerning determination of nitrate levels in food<br />
products has been observed, essentially due to the<br />
potential reduction of nitrate to nitrite, which is<br />
known to cause adverse effects on human and<br />
animal health. Therefore, the monitoring and<br />
surveillance of the quality of vegetal products need<br />
to be enhanced.<br />
Nitrates and nitrites may accumulate in<br />
plants tissues and are very dangerous substances<br />
for human health, leading health disturbances<br />
(methemoglobinemia). Some epidemiological<br />
studies linking intake of nitrate and nitrite with<br />
gastric cancer in humans indicated a positive<br />
correlation.<br />
Nitrogen is absorbed by plants in the form of<br />
either ammonium (NH 4+ ) or nitrate (NO 3– ), and its<br />
accumulation is influenced by a series of factors<br />
that are depending on the species, cultivar, age and<br />
soil conditions. Once nitrate is absorbed by plants,<br />
it has to be reduced by the enzyme nitrate<br />
reductase to ammonium and assimilated via<br />
glutamate. The concentration and amount of<br />
nitrates levels in plants will vary depending on the<br />
type of vegetable, the temperature that it is grown<br />
at, the sunlight exposure, soil moisture levels and<br />
the level of natural nitrogen in the soil.<br />
In relation to age, preferential tomatoes<br />
absorb at the beginning of vegetation form<br />

Simion, Câmpeanu, Gh., Gina, Vasile, Mihaela,<br />
Artimon, Luminiţa, Catană, Mioara, Negoiţă,<br />
2008; Davidescu, D., Davidescu, Velicica, 1987].<br />
Vegetables tend to concentrate nitrate ions,<br />
especially if they are grown by using a high<br />
application of nitrogen fertilisers. If nitrate levels<br />
in vegetal products are too high, farmers must<br />
reduce the amount of nitrogen fertilizers they use,<br />
though the problem from the farmer point of view<br />
is that by reducing nitrogen applications is likely to<br />
obtain lower yields.<br />
Also, it is known that molybdenum is a<br />
component of nitrate reductase enzyme, which has<br />
an important role in plant nitrate metabolism.<br />
Lower concentrations of molybdenum in<br />
plants lead to nitrate accumulation in tissues and<br />
sometimes, a higher level of nitrate is a<br />
consequence of this wait.<br />
The major contribution of the intake of<br />
nitrates in food comes from vegetables. Nitrates<br />
are natural components of plants and are present in<br />
large quantities in many vegetables.<br />
As a result of many factors that influence the<br />
process of accumulation of nitrates in vegetables,<br />
data from the literature usually indicates a large<br />
variation of content of nitrates. Concentrations of<br />
nitrates in tomatoes varies between 10-100 mg/kg.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
The amount of nitrates in general decreases<br />
as plant, green maturing have higher levels of<br />
nitrates than mature.<br />
Accumulation of nitrites in the fresh<br />
products of vegetable origin is reduced, they<br />
represent a transitional stage in the processing of<br />
nitrates by endogenous reductases. As the nitrites<br />
is formed by the action of the enzyme nitrate<br />
reductase, they shall be reduced further with the<br />
same speed of nitrite reductase, oxides of nitrogen<br />
ammoniacal nitrogen up to. The process takes<br />
place in the leuchoplasts of the root or in the<br />
chloroplasts of leaf. The degree of reduction<br />
depends on genetic factors and the role of electrons<br />
from NADPH+H + . So it explains why different<br />
quantities of nitrates in vegetables are much higher<br />
than the amounts of nitrites.<br />
After harvesting the vegetables kept in<br />
inadequate conditions favouring the development<br />
of microorganisms, leading to the accumulation of<br />
large amounts of nitrites by reducing nitrates. This<br />
fact is explained by the decrease of nitrite and<br />
nitrate reductase increase in activity of endogenous<br />
or microbial origin. In this case the concentration<br />
of nitrites can reach very high values<br />
(approximately 360 mg/kg dry matter) (Clemensa,<br />
Tofan, 2001].<br />
In tomatoes intended for processing are<br />
specific sources of pollution and contamination.<br />
Stagnation in manufacturing technological<br />
flow derivatives are also causes of conversion of<br />
nitrates into nitrites (Andrei, Corina, 2011).<br />
During the processing necessary to select<br />
those processes to ensure reduction of nitrates. So,<br />
wash with plenty of water and boiling hot<br />
moulding or short-lived, with removal of water,<br />
nitrates can reduce up to 30% of the initial quantity<br />
(carrots, spinach, potatoes, but not in red beets).<br />
The presence of nitrates/nitrites in large<br />
quantities in food can create a number of<br />
technological problems in the preservation<br />
industry: corrosion of metallic tin packaging, or the<br />
opportunity of formation of nitrogen oxide during<br />
sterilisation, which causes the camber boxes and<br />
even their explosion (Watson, D., H., 2002;<br />
Clemensa, Tofan, 2001).<br />
Because of the potential hazards to health as<br />
a result of high intake of nitrates and nitrites,<br />
determination of the content of these ions in the<br />
tomato was considered and measured in many<br />
countries (Vasilica, Simion, Câmpeanu, Gh., Gina,<br />
Vasile, Mihaela, Artimon, Luminiţa, Catană,<br />
Mioara, Negoiţă, 2008).<br />

MATERIALS AND METHODS<br />
Biological material used for the analyses was<br />
the tomatoes harvested at maturity, in Tulcea County,<br />
and for recovery within S.C. Contec Foods S.R.L<br />
Tecuci.<br />
Figure 1 Tomatoes and tomato juice<br />
Samples were collected in October 2011.<br />
This study analyzed the levels of nitrates and<br />
nitrites in raw tomatoes, chopped tomatoes thermal<br />
treated, residue of skin and seed, and tomato juice of<br />
finished product.<br />
The obtained results were correlated with the<br />
limits laid down by the legislation in force (Figure 1).<br />
Defining stages of processing regarded as<br />
critical points of sampling in the analysis of the<br />
dynamics of the nitrates and nitrites content are<br />
presented in Figure 2.<br />
Figure 2 Stages of processing tomatoes<br />
for tomato juice<br />
Determination of the content of nitrates and<br />
nitrites were carried out by molecular absorption<br />
spectrometry method.<br />
Determination of nitrites is based on their<br />
reaction to the pH 1.9 with reagent 4-amino benzene<br />
sulphonamide in the presence of orthophosphoric<br />
acid, to form a salt of diazonium forming a complex<br />
with red color with N (1-naphthyl reagent) – ethylene -<br />
diamine, which measure the absorbance at 540 nm.<br />
Trace the calibration curve was made into a<br />
series of nine volumetric flasks of 50 ml, where<br />
volumes have been introduced by a standard solution<br />
of nitrite nitrogen concentration of 1 mg/l, indicated in<br />
the table below (table 1).<br />
It was carried out and a blank, but replacing<br />
the sample with ultrapure water.<br />
Determination of the content of nitrates is<br />
performed in a series of bottles of evaporation, where<br />
they added 1 ml, 2 ml, 3 ml, 4 ml and 5 ml nitrate and<br />
0.5 ml solution of sodium azide and 0,2 ml of acetic
acid. After 5 minutes added 1 ml of sulphuric acid, to<br />
dissolve the residue in the flask. Added 10 ml of<br />
distilled water and 10 ml of the alkaline solution.<br />

The mixture obtained has been into a<br />
volumetric flask at 25 ml and put in water bath at a<br />
temperature of 25°C, for 10 minutes, and then it was<br />
brought up to the mark with water. The absorbance<br />
measured at wavelength of 415 nm in cells with<br />
optical path 40 mm or 50 mm, with reference to<br />
distilled water.<br />
RESULTS AND DISCUSSION<br />
The results obtained from samples allow us<br />
to state that they are much smaller than the<br />
maximum permissible concentrations (CMA) by<br />
the legislation in force.<br />
Results on the content of nitrates and nitrites<br />

Level of nitrates in tomato juice looked<br />
varied between 5.04-5.27 mg/kg, with an average<br />
of 5.12 mg/kg. The average highest nitrate was<br />
found in raw tomatoes (7.74 mg/kg), which<br />
subsequently dropped after washing (2 washing<br />
149<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
with cold water, 2 showers) and preheating 60-<br />
70 ° C, with a concentration of 5.25 mg/kg (figure<br />
3).<br />
Figure 3 The effect of processing<br />
on the content of nitrates, mg/kg<br />
This quantity of nitrates leachate dropped<br />
due to the composition of the heat treatment<br />
(preheating to 60-70° C for 4 minutes) after which<br />
the NaCl was added at the rate of 0.35%.<br />
Surveys say that nitrates are stable chemical<br />
substances and which do not fall under the action<br />
of oxidants and temperature, but is characterized<br />
by a high solubility in water (Tărâţă, V., 1992).<br />
Nitrates, a dangerous compound for the<br />
quality of finished product, measured in it are well<br />
below 150 mg/kg (CMA as specified in the<br />
Ordinance the Government Romania No. 1/2002)<br />
on all samples.<br />
The same situation is found and to nitrites,<br />
where the values of this compound are well below<br />
3 mg/kg.<br />
The level of nitrites in tomatoes and<br />
products resulting from technological flow are very<br />
small, less than 1 mg/kg (figure 4). Anyway, the<br />
content of nitrites in plant products are generally<br />
lower than those in the nitrate.<br />
Figure 4 The effect of processing<br />
on the content of nitrites, mg/kg<br />
Content of nitrites in tomatoes vary between<br />
0.022-0.051 mg/kg, with an average of 0.032<br />
mg/kg.<br />
Content of nitrites in tomato juice is lower<br />
by about 50% in raw material, while the content of<br />
the highest technological steps to be taken in the
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
study was obtained in skins and seeds obtained as<br />
residue from the processing of tomatoes.<br />
CONCLUSIONS<br />
Influence of processing steps taken in the<br />
study on the nitrate content of lowering their<br />
concentrations at a level of 7.74 mg/kg in raw<br />
tomatoes, at a value of 5.12 mg/kg in the finished<br />
product.<br />
As regards the content of nitrites in tomato<br />
juice (0.014 mg/kg) it is lower than for the<br />
corresponding content of tomatoes was 0.032<br />
mg/kg.<br />
High concentrations of nitrates and nitrites<br />
was recorded in skin and seed obtained as residue<br />
from the processing of tomatoes.<br />
Analysis of nitrates and nitrites shows a<br />
tomato juice containing normal in these<br />
compounds, so a good quality for human<br />
consumption and marketing.<br />

Country's arable land is 8.4 million hectares, of which 1.26 million hectares (15%) are barren. Average recommended<br />
consumption of milk is 240 l/year/person, while in developed countries it is between 280 and 440 l/year/person. The<br />
objective of this paper is to determine whether cultivating barren lands could bring an increase of production so as to<br />
ensure an optimum consumption of milk and dairy products. If the barren lands from the NE area of development would<br />
be cultivated with forage crops, it might get a production of about 873 thousand to of fodder. In Neamt county, from the<br />
use of barren lands, the optimal consumption for milk and dairy products should be provided (303 l/inh.), counties such<br />
as Suceava and Botosani making even surplus yields (740 l/inh., respectively 528 l/inh.). In Iasi, Vaslui and Bacau<br />
counties, it could only be realized a minimum or a little over minimum consumption (192 l/inh, 210 l/inh., 207 l/inh.).<br />
Key words: forrage base, milk consumption, barren lands<br />
Country's arable land is 8.4 million<br />
hectares, of which 1.26 million hectares (15%) are<br />
barren. Arable land has become a geopolitical issue<br />
because global security is threatened by famine<br />
(Smith 2009). We are ranked 12th in the world<br />
vulnerable to hunger among African countries.<br />
Dairy cows fed high-quality forage produce more<br />
milk with less supplemental concentrate than cows<br />
fed lower-quality forage (Radu 2011; Vladu et al.<br />
2007; Weiss et al. 2007). Livestock, their health<br />
and productive capacity depends largely on the<br />
provision of fodder throughout the year, rich in<br />
various chemical constituents (Pop et al. 2002;<br />
Stoica 2006; Vaida et. al 2010). Grazing<br />
management has a greater effect on the pasture<br />
than any other part of the pasture management<br />
program. Poor grazing management can lead to the<br />
loss of some species in the pasture and the loss of<br />
forage yield (Barnes et al. 2007; McDowell 2009;<br />
Redecker et al. 2002; Vîntu et al. 2004). Cattle’s<br />
milk contains more of the essential vitamins and<br />
mineral required by the human than any other<br />
single food (Patton 2005; Chandan et al. 2008). In<br />
our country, the milk and dairy products<br />
consumption is quite limited, and the quantity per<br />
capita consumption is much lower than in other<br />
developed countries. The literature indicates that,<br />
to maintain human health, it would be necessary to<br />
annually consume 300 liters/capita (by WHO), 240<br />
l/capita (FAO), or at least 0.5 liters per day (180<br />
l/capita), including also butter or cheese.<br />

MATHERIALS AND METHODS<br />
The methodology used in the paper had the<br />
specific marketing methods and geo-economic study<br />
based on the investigated area, direct observation,<br />
agricultural statistics, analysis of comparative<br />
economic record, economic experiment, monographic<br />
method, simple division method and comparison<br />
method, analysis and synthesis.<br />
The study was conducted based on data<br />
reported by Romania's Central Technical Secretariat<br />
from General Agricultural Census, which took as the<br />
reference date 1st of December 2010. Barren lands<br />
are agricultural lands that have not been worked in<br />
the reference year of the census, were not included in<br />
the rotation system and it is not maintained in good<br />
agricultural and environmental conditions. The<br />
analysis was made on the North-East region of<br />
development, which includes the counties Bacau,<br />
Botosani, Iasi, Neamt, Suceava and Vaslui.<br />
RESULTS AND DISCUSSIONS<br />
Although Romania is the middle ranking of<br />
the largest milk producing country, with a volume<br />
of 232 l / capita, ahead of most markets in the<br />
region and on a level with England and the Czech<br />
Republic, local industry is insignificant in the<br />
market milk of European Union. Only 1 in 5 liters<br />
of milk reaches the processing industry and 40%<br />
are for self-consumption.<br />
According to Eurostat, the whole country, in<br />
2010, fallown land totaling 904,000 hectares. If it
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
had cultivated with forage crops could get a yield<br />
of about 9040000 to. This production could feed a<br />
herd of about 496,703 dairy cows.<br />
Average milk production throughout the<br />
country is 3528 l / head, we may appreciate that<br />
after cultivation of fallown land, we could get a<br />
surplus of milk production of about 17.522 million<br />
hl.<br />
Adding the existing surplus production<br />
3.944 million tons, we obtain a value of 39457.5<br />
million hl. This production involves milk<br />
consumption of about 183 l / capita, a value much<br />
closer to the optimal consumption of milk and<br />
dairy products.<br />
In the NE region, the largest area of fallown<br />
land is located in Bacau, while in Suceava County<br />
there is the lowest area of fallown land (figure 1).<br />
152<br />
In case the barren land would be cultivated<br />
with forage crops (table 1), the production<br />
obtained by each county would have the following<br />
values:<br />
Iasi: 7.1 • 9087.38 = 64520.4 to;<br />
Vaslui: 11.2 • 15886.57 = 177929.6 to;<br />
Bacau: 15.9 • 24225.57 = 385186.5 to;<br />
Suceava: 17.2 • 2320.63 = 39914.8 to;<br />
Botosani: 11.3 • 12514.32 = 141411.8 to;<br />
Neamt: 12.1 • 5312.42 = 64280.3 to.<br />
The total development area of forage<br />
production derived from barren land cultivation<br />
would be 873240.4 to.<br />

cultivation of barren lands, per total development<br />
area would be 873,240.4 to, production with which<br />
Table 3<br />
dairy herds could increase by about 10 %. Milk<br />
production obtained from this livestock would be<br />
of 944 thousand hl, which would ensure optimum<br />
consumption in the counties of Suceava, Botosani<br />
and Neamt and ensure a minimum consumption for
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
counties Iasi, Vaslui and Bacau. The highest per<br />
capita consumption growth is recorded in the<br />
county of Bacau, Vaslui county with 35 % and<br />
about 19 %, this due to the large surface of barren<br />
area.<br />

PHYSICAL AND CHEMICAL CHARACTERISTICS OF WATER<br />
IN A MICROWAVE FIELD AND MASS TRANSFER<br />
DURING THE DRYING OF DENSE TEXTILES<br />

Microwave drying provides economic advantages based on optimised energy consumption and productivity deriving<br />
from the changes in physical and chemical properties of water in a microwave field: heating rate, as influenced by<br />
chemical composition, volume, the presence of the heat transformer; volume expansion, vapour pressure, rH,<br />
evaporation rate and the evaporation parameter – all measured in relation to temperature, time and power. For example,<br />
in the case of felt, energy consumption is reduced from 4-6 kWh in classical drying to 1.7-2.3 kWh during microwave<br />
drying per 1 kg of dried water. In addition, the drying period is shortened from 200-400 min. in classical drying to 60-<br />
140 min. in microwave drying. Thus, based on drying time alone, productivity increases 3 to 4 times. Each material<br />
subjected to a drying process is characterised by typical energy consumption and productivity levels.<br />
Key words: water, field, microwave, trensfer, drying<br />
The microwave heating of dielectrics in a<br />
cavity resonator has emerged out of the necessity<br />
to increase the power transformed into heat, by<br />
using ultra high frequencies, the intensity of the<br />
electrical field being limited due to dielectric<br />
rigidity. According to the general classification,<br />
microwaves are defined as the area of the<br />
electromagnetic spectrum ranging between f = 0.3<br />
GHz and f = 6.10 3 GHz ( = 0.05 - 10 3 mm); based<br />
on other definitions set the boundaries of the<br />
microwave spectrum between f = 1 and 3.10 2 GHz<br />
( = 1-3.10 2 mm).<br />
Interaction effects can be thermal or nonthermal.<br />
Non-thermal effects are generated at high<br />
potential (> 100 V/cm) and at low potential. This<br />
refers to: the saturation of dielectrics, the<br />
orientation of colloidal particles, the molecular<br />
resonance of microscopic-scale biological<br />
structures, etc.<br />
As regards thermal effects, the specific<br />
power [W/m 3 ] dissipated in the material is<br />
expressed by the relationship:<br />
PV = 0.5 ∙ ael∙E 2 + 0.5 ∙ 0∙ "∙ ∙E 2 +<br />
0.5∙ 0∙ "∙ ∙H 2 [W/m 3 ]<br />
Where ael – electric conductibility [S/m]; -<br />
electric permittivity [F/m]; " - magnetic<br />
permeability [H/m]; E, H – the intensity levels of<br />
the electric field [V/m] and, of the magnetic field<br />
[A/m] respectively.<br />
If ael = 0 and " = 0, :<br />
PV = 0.55∙10 -10 ∙ "∙f∙E 2<br />
with " = '.tg el and " = '.tg m.<br />
These values define the dielectric properties<br />
of a material and characterise its behaviour under<br />
the influence of a high-frequency field<br />
(microwaves), being dependent on frequency,<br />
humidity, temperature, etc.<br />

MATERIALS AND METHODS<br />
A laboratory set-up was assembled from<br />
commercial components, similar in principle to regular<br />
components, with maximum output power of 800 W<br />
and a frequency of 2450 MHz. Initial power (P) was<br />
set on three levels: 350, 500, 650 W. The cavity<br />
resonator features:<br />
- reaction bowl;<br />
- PC-linked digital thermometer for automatic<br />
recording during the charging break of the<br />
magnetron;<br />
- pressure manometer (0 – 300 mmHg);<br />
- ORP system for the simultaneous<br />
measurement of temperature, pH, electrode potential,<br />
connected to a PC and charged through a connection<br />
loop in the generation break of microwaves;<br />
- pycnometer with volumetric pipette.<br />
Materials<br />
Measurements of the cavity resonator: L x l x H<br />
= (350 x 228 x 343) mm and volume 27.3 l.<br />
Heating rate<br />
The power of microwaves is a key factor with a<br />
significant influence on the heating rate. If greater<br />
power is applied, then an increased heating rate of<br />
the object subjected to heating is to be expected.<br />
The dependence between the power of<br />
microwaves applied during heating and temperature<br />
increase can be rendered by the equation below:<br />
T<br />
P t<br />
V c<br />
p<br />
where: ΔT – temperature increase of the<br />
heated object;<br />
P – power of microwaves used for heating;<br />
ρ, V, c p – the density, volume, specific heat<br />
(kg/m 3 , m 3 , and J/(kg 0 K), respectively), t – heating<br />
time, s.<br />
The output efficiency of the set-up is<br />
dependent on the frequency and on the<br />
measurements and volume of the cavity typical of<br />
each set-up.<br />
The initial power absorbed by water (IEC<br />
standard IEC 705 – 1988, V = 1000 ml, T 0 = 10 ± 2<br />
0 C) is expressed by the previous equation adjusted<br />

Determining the rH for polymolecular<br />
water fractions<br />
The relative hydrogen score, rH, was first<br />
proposed to the research community (mostly<br />
inorganic chemists) by Clark in 1923, as a means<br />
to measure the actual reduction of hydrogen in an<br />
aqueous solution of simple antioxidant compounds<br />
and is based on a variant of the Nernst equation.<br />

Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
The rH range is from 0 to 42, with 28 being<br />
the median value. Below the 28 point reduction<br />
occurs, and oxidation above the 28 value. The<br />
extreme values, 0 and 42, indicate the maximum<br />
reduction and oxidation rates, respectively.<br />

For the various initial power values (P0 =<br />
350, 500, 650 W), after different irradiation<br />
periods, t (min.), water temperature, T ( 0 C), was<br />
measured and the Matlab software environment<br />
was used for mathematical calculations and<br />
graphical representations of the dependencies:<br />
- mass loss by evaporation, M(g);<br />
- water mass evaporated, M (%), in relation to t<br />
(min.) and P (W) ;<br />

CONCLUSIONS<br />
Microwave drying presents economic<br />
advantages derived from optimised energy<br />
consumption and increased productivity. For<br />
instance, in the case of felt, energy consumption is<br />
reduced from 4-6 kWh in classical drying to 1.7-<br />
2.3 kWh during microwave drying per 1 kg of<br />
dried water. In addition, the drying period is<br />
shortened from 200-400 minutes in classical drying<br />
to 60-140 minutes in microwave drying. Therefore,<br />
based on drying time alone, productivity increases<br />
3 to 4 times.<br />
Each material subjected to a drying process<br />
exhibits typical energy consumption and<br />
productivity levels.<br />

Colour is an individual visual perception that is dependent upon numerous factors. Colour cannot be measured directly<br />
unlike the mass of a body or its geometric characteristics (length, width, height). Using the key elements in the complex<br />
system of viewing/rendering/reproducing colour, which involves: the source of light, the coloured object, the observer<br />
(receiver), the paper presents the importance and standard of each component, highlighting the specifics of colour<br />
assessment, for additive and subtractive systems, including the particular steps of the direct RGB model and the<br />
opposite CMYK model. Based on preliminary complex mathematically processed data, the paper presents the algorithm<br />
for developing and structuring the various colour spaces that serve to represent colours: LMS, RGB, CIEXYZ, CIExy,<br />
CIELab – which has become a universal space that encompasses lightness L and two chromatic components, i.e. a - the<br />
green to magenta range and b – the blue to yellow, CIELuv – recommended for its uniformity, and HSB (hue,<br />
saturation, brightness) – typically used for dependent systems, etc. The paper emphasises the particular characteristics<br />
and gamut of each colour model. The variants CIEDE 1976, CIEDE 1994, CIEDE 2000 used in calculating colour<br />
difference are also provided. Moreover, an analysis of colour evaluation criteria is presented and, based on the<br />
conclusions, the adequate representation space is recommended. The author’s personal contribution is limited to the<br />
colour spaces for three types of soil under humidity conditions; three types of leaves and grass, four types of gladioli<br />
and the colour of the red cabbage extract in connection with pH – which are all characterised by natural colour.<br />

LMS, CIERGB Independent colour spaces<br />
and the imaginary space CIEXZY. Vector analysis.<br />
The science of colour - colorimetry - operates<br />
with the LMS, CIERGB and CIEXYZ colour spaces<br />
that can be represented mathematically as vectors in<br />
3D space. Due to trichromatic vision, a colour (C)<br />
may be represented by a vector whose magnitude is<br />
proportional to the light level, while orientation is<br />
linked to colour. At a random point C one can<br />
determine the contribution of primary colours (their<br />
individual share).<br />
Figure 4 Vectorial representation of a colour (C)<br />
The vector C is represented in the system of<br />
coordinates C1, C2, C3, known as trichrome coordinates,<br />
in which the unitary vectors P1, P2, P3 are defined as<br />
representing the primary composing colours.<br />

Any random colour can be characterised by three<br />
tristimulus values (L, M, S), (R, G, B), (X, Y, Z), (L*, a*,<br />
b*), etc. For each colour space, the three-dimensional<br />
contour is defined in addition to its projection on the<br />
horizontal plane, known as locus.<br />

space.)<br />

In the CIExy locus can be positioned the<br />
monochromatic sources in the CIERGB space with the<br />
wavelengths: R = 700 nm, G = 546.1 nm, B = 435.8 nm.<br />

In the RGB triangle the Hermann Günther<br />
Grassmann colour composition laws apply, for example<br />
in the C(r,g,b) point:<br />

Linear transformations can be performed<br />
between colour spaces.<br />
RESULTS AND DISCUSSIONS<br />
The CIEXYZ imaginary space - each point<br />
corresponding to a colour in the imaginary<br />
CIEXYZ space or in the corresponding CIExy<br />
locus is determined by means of the general<br />
algorithm which includes as known data: the<br />
spectral reflection / transmission curve, the<br />
illuminant’s energy feature and standard functions<br />
of colour composition.<br />

depending on pH for red cabbage extract<br />
CONCLUSION<br />
Except for two samples (cabbage extract at<br />
pH 3 and pH = 10), the CIE xy points are located<br />
in the sRGB colour rendering space. This suggests<br />
the fact taht further direct methods of colour<br />
analysis may be employed.<br />
Figure 24 Experimental data in the sRGB space<br />
Wet soils have lower L,A,B values than dry<br />
soils and less colour difference from standard.<br />
Grass is significantly more yellow than<br />
leaves (the highest b+ value). Over time, leaves<br />
become increasingly greener (higher a- values).<br />
In the CIELAB space, the a and b values<br />
cause a clear distinction between gladioli: a + -<br />
green, a- - red, b + - yellow, b- - blue.<br />
164<br />
In the CIEL*AB colour space, colours differ<br />
significantly based on their location.<br />
By using the CIEDE2000 formula to<br />
compute colour difference uniform and limited<br />
differences between the coloured samples are<br />
obtained.<br />

Braking process of a vehicle is complex, giving possibility to the driver to reduce car’s speed or to stop it at big speed in<br />
a short distance. Using the diagrams registered for the different working conditions, defined accordingly with the<br />
experimental plan, there have been analyzed the values of deceleration, variation of speed and the covered space for<br />
each specified moment of braking. As result of the experimental researches, we have reached the conclusion that a good<br />
behavior at cars braking is registered when the diagrams of deceleration variation in relation with braking time have a<br />
symmetric shape.<br />
Key words: vehicle stability, experimental braking process, ABS<br />
Braking process of a vehicle is complex,<br />
being defined by factors leading to different effects<br />
from the point of view of impact, intensity and<br />
duration.<br />
The braking system gives possibility to the<br />
driver to reduce car’s speed or to stop it at big<br />
speed in a short distance.<br />
Last generation cars are endowed with:<br />
-Service brakes;<br />
-Backup brakes;<br />
-Handbrake;<br />
-Auxiliary brake.<br />
From the point of view of the vehicle’s<br />
control and safety, the most important is the<br />
service braking system (the foot brake).<br />
The longitudinal deceleration ax is one of the<br />
main parameters of the braking system, which can<br />
be calculated with formula:<br />
(1)<br />
where φx is the longitudinal coefficient of<br />
adherence of the tires with the running path and g –<br />
the gravitational acceleration (g = 9.81 m/s 2 ).<br />
The Directive of EU 71/320 (Council<br />
Directive 71/320/EEC, 1971) shows that this<br />
criterion has to satisfy the following condition:<br />
(2)<br />
In the specialty literature, the given value for<br />
the adherence of the tires with the running path on<br />
a dry asphalt is φx = 0.8.<br />
Introducing this value, which applies only to<br />
the vehicles and tires produced until 1980, in<br />
relations (1) and (2), there results the deceleration<br />
of a vehicle in good technical conditions, at<br />
braking on a dry asphalt<br />
ax = 6.0 – 7.85 [m/s 2 ]<br />
In the situation of actual cars, the maximum<br />
coefficient of adherence has the value φx = 1– 1.2<br />
(Mitunevicius V., 1999) , if braking takes place on a<br />
running path with dry asphalt, situation when the<br />
deceleration of old cars with tires produced at the<br />
present moment can reach values in the range<br />
7.35÷ 9.3 [m/s 2 ].<br />
The modern cars are endowed with systems<br />
which prevent wheels blocking (ABS) and the real<br />
braking distance is quite close to the calculated<br />
value obtained with the maximum values of the<br />
coefficient of adherence. In this situation, the<br />
deceleration can be close to g = 9.8 [m/s 2 ].<br />
1. ANTI-BLOCKING SYSTEMS (ABS)<br />
Anti-blocking System is used at cars for<br />
avoiding the blocking of wheels during braking,<br />
for providing the stability of the vehicle and an<br />
optimal deceleration.<br />
Anti-blocking of wheels is realized by<br />
adapting the braking force at each wheel, function<br />
of the wheel’s adherence to the running path.<br />
The advantages of a system (Neculaiasa V.,<br />
1996) assure keeping the vehicle under control,<br />
although the braking and the side forces are<br />
increasing, on a minimum braking distance with a<br />
reduced wear of tires.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Some of the conditions to be accomplished<br />
by an ABS are following presented:<br />
1. ABS must function on all the range of speeds;<br />
2. ABS must correspond to the conditions of<br />
adherence with the running path;<br />
3. To assure the steering of vehicle at slippages<br />
appearance;<br />
4. To recognize aquaplaning and to respond to it;<br />
5. To rapidly and automately correlate the<br />
hysteresis of tires at specific conditions;<br />
6. The option of engine brake to be possible;<br />
7. If an error at the ABS functions occurs, during<br />
braking, the braking system must function<br />
normally on classical principles.<br />
The functioning principle of the antiblocking<br />
system is based on rapid braking without<br />
wheels blocking, by applying short and rapid<br />
actions having as objective the delay of wheels<br />
blocking. This process is realized by the action<br />
upon the pressure of brake fluid from the brake<br />
installation, regulated to avoid the wheel blocking<br />
regardless the adherence to the running path.<br />
In figure 1 (GillespieT. D., 1992) there is<br />
presented the diagram of variation for the speed of<br />
a vehicle with ABS in relation with the braking<br />
time, for the four wheels of the car.<br />

Figure 1 Variation of speed<br />
in relation to the breaking time.<br />
When the brake pedal is acted, the value of<br />
wheels rotational speed is decreasing due to a true<br />
value depending to the vehicle’s speed (pt.1 from<br />
figure 1). When the force which the brake is<br />
pressed with is bigger or the running path is<br />
slippery, the rotational speed of wheels<br />
significantly reduces (pt.2). In pt.3, ABS is<br />
activated and releases the brakes. When the<br />
rotational speed of wheels increases again, the<br />
brakes are once again activated, the process being<br />
repeated until the vehicle is brought to the desired<br />
speed.<br />
1.1. Braking of vehicles without wheels<br />
blocking<br />
t<br />
166<br />
If the car is not endowed with a regulator of the<br />
braking force of the ABS, the total braking force is<br />
differently distributed between the vehicle’s<br />
bridges, from which reason the wheels of the front<br />
bridge and those of the rear bridge are not<br />
simultaneously blocked.<br />
In the situation that the wheels have a good<br />
adherence to the surface of the running path, the<br />
rear wheels are first blocked, context in which the<br />
vehicle may lose transversal stability and if the<br />
front wheels are blocked, the control of the<br />
advancing direction can be lost.<br />
A good behavior during braking is met when<br />
the motion of the car is continued in straight line at<br />
brake action, even for great speeds, condition<br />
imposed accordingly to the Directive of EU<br />
71/320. So, in the moment when the emergency<br />
brake is acted, the motion of the car must continue<br />
in straight line, it means a bigger relative braking<br />
force upon the front wheels must be provided, in<br />
comparison with the force acting on the rear<br />
wheels.<br />
The coefficient of distribution of the braking<br />
force (Illarionov, V. A., 1997) represents the ratio<br />
of the braking force acting on the front wheels, to<br />
the total braking force, acting on all the wheels.<br />
βT = PST1 / (PST1 + PST2) (3)<br />
PST1 and PST2 – represent the braking forces upon<br />
the front wheels and respectively upon the rear<br />
ones and they depend on structure of the brake<br />
system. This coefficient (βT) can be calculated for<br />
any type of vehicle [5], accordingly to the known<br />
parameters of the brake system.<br />

Figure 2 Scheme of forces in the process<br />
of braking without wheelss blocking.<br />
In the situation of neglecting the loss of<br />
energy, for overcoming the resistance forces, the<br />
maximum of the deceleration for a vehicle at the<br />
limit of rear wheels blocking will be:<br />
ax = (4)
Where: l1 = the distance in longitudinal direction,<br />
between the mass center of the vehicle and the<br />
front wheel, L represents the distance between<br />
wheels (the wheelbase) and hc is the height of the<br />
mass center.<br />
The maximum deceleration of a vehicle at<br />
the limit of front wheels blocking is:<br />
ax = (5)<br />
Where: l2 = the distance between the rear wheel<br />
and the car’s mass center.<br />
The optimum coefficient of adherence φopt ,<br />
will be given by relation:<br />
φopt = (L . βT – l2 )/ hc (6)<br />
In the conditions when the correct value of<br />
the coefficient of adherence exceeds φopt, the rear<br />
wheels will be firstly blocked by braking and<br />
relation (4) allows calculation of deceleration. In<br />
the situation when the value of the coefficient of<br />
adherence is smaller than the optimum value φopt,<br />
the front wheels will be the first blocked when the<br />
vehicle braking and the expression (5) will be used<br />
for calculate the deceleration.<br />
When φopt has a value close to zero or is<br />
negative, only the rear wheels will be blocked in<br />
any situation of motion.<br />
In the situation of a vehicle with unblocked<br />
wheels, the braking distance is calculated with<br />
formula:<br />
S0 = (t1 + t2 + 0.5 . t3) . v0 + v0 2 /2ax (7)<br />
In the situation when the initial speed of the<br />
vehicle (v0) is not known, the braking distance of a<br />
vehicle with unblocked wheels (unlike the case of<br />
blocked wheels, when the slip length can be<br />
measured) can be determined with certain errors<br />
and this circumstance can influence the correctness<br />
of the obtained results.<br />
In the situation of emergency braking, the<br />
braking forces acting on the vehicles’ wheels<br />
should not exceed the forces of adherence of the<br />
tires at the running path, the calculated value of the<br />
deceleration of a vehicle with blocked wheels will<br />
be smaller and the braking time and braking<br />
distance will be bigger, in comparison with the<br />
case when the coefficient of adherence is known.<br />

vehicles with ABS and without ABS<br />
167<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
From the study of vehicles’ theory, the<br />
deceleration of a vehicle in good technical<br />
conditions without ABS reaches the top, fig.3, just<br />
at the beginning of the braking process and then<br />
some decreasings are happening, due to the fact<br />
that the top of deceleration is reached before<br />
blocking the vehicle’s wheels.<br />
Figure 3 Diagram of braking with ABS-phase<br />
of starting the braking process.<br />
After the wheels blocking, a decrease of the<br />
deceleration takes place, because braking of a<br />
blocked wheel is less efficient [6].<br />
Maximum of deceleration lasts more during<br />
the braking of a vehicle without ABS at a lower<br />
speed; at a bigger speed, when the braking time is<br />
greater, the top of deceleration lasts less. This fact<br />
explains the decrease of speed for vehicles without<br />
ABS when a certain displacement speed is reached.<br />
In fig.4 the diagram of variation of<br />
deceleration in relation with time is presented,<br />
during the period of speed variation of vehicle<br />
without ABS.<br />
In specific road conditions, the value of the<br />
vehicle’s deceleration may have a bigger<br />
correctness, which imposes an experimental<br />
research.<br />
The deceleration of a vehicle on a running<br />
path can be measured using a special device<br />
(decelerometer) or can be calculated with relation<br />
(Sokolovsku E., 2004), if the initial speed v0 and<br />
the braking distance are known.<br />

The experiments have been done in the<br />
testing ground of Daewoo Craiova cars factory, on<br />
different running paths with surfaces covered with:<br />
asphalt dry - wet, gook, glaze, snow, car empty –<br />
loaded, engine clutched – declutched, and also in<br />
normal conditions of circulation on national roads<br />
in Botosani County, with the Testing Laboratory<br />
owned by SC ROMTURINGIA.<br />
In the experiments, a device for measuring<br />
vehicles’ deceleration (decelerometer) type MAHA<br />
VZN 100 was used. The device is appropriate for<br />
such measurements both for vehicles with<br />
hydraulic and pneumatic brake system and for<br />
those with ABS, as in fig.5.<br />
The device is compound of: control board,<br />
for data displaying and registering; transducer<br />
wheel with its fixing support; flexible drive cable<br />
and dynamometric pedal (specific for braking<br />
tests).<br />
The transducer wheel transmits rotational<br />
motion by the flexible cable to the control board,<br />
for displaying and registering, where the<br />
displacement speed can be read at any moment. In<br />
the registering apparatus, a time base is embedded,<br />
which electrical signals, at a period of one second,<br />
are marked on the registering paper, moving by<br />
rolling on the internal drums, with a speed<br />
proportional with the speed the wheel is running on<br />
the ground.<br />
The used device measures the process<br />
parameters and draws the corresponding diagrams<br />
for speed, deceleration and the covered space,<br />
function of the type of braking.<br />
The conformity of the measuring device<br />
VZN 100 with the standards stipulated for the<br />
device’s checking is certified by the German<br />
Association for Technical Inspection (TUV) [5].
This device is also used by the Lithuanian centers<br />
for technical inspection for establishing the<br />
efficiency of the brake system, basing on the<br />
maximum deceleration.<br />
Using the diagrams registered for the<br />
different working conditions, defined accordingly<br />
with the experimental plan, there have been<br />
analyzed the values of deceleration, variation of<br />
speed and the covered space for each specified<br />
moment of braking.<br />
As result of the experimental researches, we<br />
have reached the conclusion that a good behavior<br />
at cars braking is registered when the diagrams of<br />
deceleration variation in relation with braking time<br />
have a symmetric shape.<br />
Based on the found parameters of vehicle’s<br />
motion, we can provide the variation of the<br />
maximum values of deceleration for specific<br />
situations.<br />

Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
CONCLUSIONS<br />
Based on the bibliographical researches in<br />
the considered technical field and on the<br />
experimental researches, certain conclusions of<br />
undoubted importance can be presented:<br />
I. In the developed experiments, the<br />
deceleration established for vehicles with ABS<br />
have varied from 8.05 m/s 2 (at the speed of 40<br />
km/h) up to 8.45 m/s 2 (at the speed of 80 km/h),<br />
and often the maximum values have been close to<br />
9 m/s 2 .<br />
For vehicles without ABS, the deceleration<br />
have varied from 7.05 m/s 2 (at speed of 40 km/h)<br />
up to 6.87 m/s 2 (at speed of 60 km/h) and up to<br />
6.65 m/s 2 at a speed of 80 km/h. When v0<br />
increases, the difference of deceleration or vehicles<br />
with and without ABS increases with 11.1%, 18%<br />
and respectively 24%.<br />
Figura 5 Principle scheme of a car endowed with the 5 th whell.<br />
II. There was calculated that the average of<br />
braking distance for a vehicle with ABS is smaller<br />
with 4.25% in comparison with those for a vehicle<br />
without ABS.<br />
If the initial motion speed is 40 km/h, and if<br />
v0 = 80 km/h, approximately the deceleration is<br />
modifying up to 15.59%;<br />
If v0 = 60 km/h, the braking distance for<br />
vehicles with ABS was of 20.80 m, and for<br />
vehicles without ABS it was of 22.42 m, the<br />
difference being of approximately 7.35%.<br />
III. The value of the braking distance can be<br />
calculated based on the braking process<br />
parameters, such as: braking time t3 , the value of<br />
deceleration axn and the initial speed v0.<br />
There is proposed the use of the values of<br />
the parameters determined within the experimental<br />
research for the examination of situations specific<br />
for traffic accidents, for a more correct defining of<br />
the methods for calculating the braking parameters<br />
for cars with or without ABS.

IV. As a result of research accomplishing,<br />
there has been noticed that the used cars are<br />
corresponding and respect the stipulations of the<br />
Regulations of braking R-13ECE – ONU. That is<br />
why the regulations of EU impose for all the cars<br />
built since 2011 the obligation of endowment with<br />
ABS.<br />

Studies on driving led to the conclusion that many drivers stop the engine or switch off the ignition while driving in<br />
order to save fuel and this entails dangerous consequences. In fact the experimental determinations performed prove<br />
that the best braking is by having the ignition on; it reduces the braking distance, it avoids locking up the tires by<br />
keeping at the same time the vehicle stability.<br />
Key words: switched on engine, switched off engine, vehicle stability<br />
Part of the driving accidents is caused also<br />
by the fact that some drivers brake by having the<br />
ignition off in order to save fuel. The braking<br />
method used and recommended is the one with the<br />
engine on.<br />
In this situation part of the vehicle energy is<br />
lost in order to overcome the segments friction of<br />
the piston on the cylinder, the friction in bearings<br />
of the crankshaft and of auxiliary mechanisms;<br />
also a mechanical work is produced because the<br />
engine acts as a compressor. (Cristea P., 1966;<br />
Fratila G. and Marculescu, 1986; Ghiulai C., 1975;<br />
Untaru M. et al, 1981).<br />
1. BRAKING WITH THE ENGINE<br />
SWITCHED ON<br />
In case of braking with the engine switched<br />
on, it grows not only the braking interval but also<br />
the possibility of locking up the wheels due to the<br />
idle interval of the engine.<br />
The braking effect of the engine will<br />
increase if the vehicle is equipped by the<br />
manufacturer with a device able, while braking, to<br />
increase the resistance when exhausting the gas<br />
burnt.<br />
Thus, if during the process of braking the<br />
ignition remains connected to the transmission, the<br />
mechanical resistances of the engine determine the<br />
appearance of a supplementary braking interval<br />
which adds to the desired effect.<br />
In the braking interval with the ignition on,<br />
the absolute deceleration is given by the relation:<br />
afm where:<br />
dv 1<br />
= Ff Ffm<br />
R<br />
ma<br />
(1)<br />
af m= - dt<br />
Where: Ff -reprezents the braking force developed<br />
by the car brakets; Ffm -reprezents the engine<br />
braking force reduced to the wheeles; ∑Rreprezents<br />
the sum of the resistances when car<br />
advances; ∂-reprezents the rotation masses control<br />
while braking with the engine switched off; ma -<br />
reprezents the mass of the car.<br />
2. BRAKING WITH THE ENGINE<br />
SWITCHED OFF<br />
When braking on a driving surface with the<br />
engine switched off, the absolute deceleration will<br />
be as follows:<br />
dv<br />
af = - =<br />
dt<br />
1<br />
ma<br />
F f R (2)<br />
-Factor of the rotating masses while braking<br />
with the engine switched off;<br />
By comparing the two relations (1, 2) it<br />
becomes obvious that braking with the engine<br />
switched on is more efficient than with the engine<br />
switched off, situation in which<br />

The curve Ffm was drawn according to the<br />
experimental determinations on stand.<br />
The hachured area between Ffm and Ff shows<br />
when breaking with the engine off is inefficient.<br />
3. RESULTS OF EXPERIMENTAL<br />
DETERMINATIONS<br />
The process of checking the braking<br />
performances is included in STAS 11960-84 and in<br />
the ECE Norms ONU13/06 amendment 09.<br />

The experimental determinations in the<br />
figure 1, ere realized in Testing Laboratories in<br />
Craiova city, Romania, by using a vehicle without<br />
ABS.<br />
The braking performances of the cars were<br />
determined without locking up the wheels ( the<br />
pressing forces on the brake pedal had the biggest<br />
possible values so as not to block the vehicle<br />
wheels). The experiment was repeated several<br />
times with the engine both switched on and off.<br />

CONCLUSIONS<br />
The experimental determinations performed<br />
both on stand and in the training area proved that:<br />
-In the case of braking with the engine<br />
switched on, in similar conditions, a supplementary<br />
Ffm force appears being caused by the frictions in<br />
the engine and transmission; the result of this is<br />
that the maxim superior force FfR at wheel braking<br />
is smaller than in the case of braking with the<br />
engine switched off.<br />
-The advantage of braking with the engine<br />
switched on is that the appearance of<br />
supplementary wheel braking interval MfR needs<br />
an Mf braking interval accomplished by the<br />
smaller braking system. As a consequence it<br />
reduces the locking up effect caused by braking<br />
when a total sliding of the wheel happens and poor<br />
stability of the car can be avoided.<br />
-While driving it is recommended to always<br />
use braking with the engine switched on because<br />
the inertia of the steering wheel and the<br />
components linked to it act as a regulating factor of<br />
the wheel braking force developed by avoiding<br />
wheel locking up and by maintaining the car<br />
stability.<br />

AGRICULTURAL CONSULTING SERVICE IN SOUTH MUNTENIA<br />
REGION DURING 2009-2011<br />
Alina DRAGOMIR 1<br />

Agriculture is a branch with huge potential in Romanian economy. Its reorganization along with EU integration requires<br />
a series of actions in sense of modernization and production increase. Romania has a privileged position from point of<br />
view of agricultural resources. Arable land represents 39.5% of the total area and only five other countries in the world<br />
have a more comfortable position than that of our country. European funds that can be drawn by the Common<br />
Agricultural Policy - approximately 7.5 billion euros during 2007-2013, contribute to agricultural potential improvment.<br />
Full exploatation of the advantages of integration into the European Union could open new opportunities for Romanian<br />
farmers who can supply a population exceeding 80 million inhabitants. In conditions of a better absorption of EU funds<br />
with direct significant investment and with an appropriate government support, the productive potential of agriculture<br />
substantially increase. Agricultural Consulting Service has a significant role in agriculture modernizing through<br />
qualification and training activities for farmers, disseminating information on funds that can be accessed and news in<br />
the field, also can meet the claim of farmers, setting with these the sell strategies for marketing of products.<br />
Key words: agricultural advisory service, South Muntenia Region, agriculture.<br />
South Muntenia Region is situated in South-<br />
Eastern of Romania, with an area of 35,453 km2,<br />
representing 14.45% of its surface. Being an<br />
administrative structure, South Muntenia Region<br />
includes 7 counties (Argeş, Călăraşi, Dâmboviţa,<br />
Ialomiţa, Giurgiu, Prahova and Teleorman), 16<br />
municipalities, 32 towns and 509 communes with<br />
2018 villages. Agricultural surface mainly<br />
concentrated in the counties of South owns 71.1%<br />
of the total area of the region from which 80.6% is<br />
arable land. According to the Regional Directorate<br />
of Călăraşi Statistics the region's population is<br />
15.4% of the country population. A significant<br />
percentage of the populations (33.20%) perform<br />
activities in agriculture field.<br />
The social dimension of agriculture is<br />
important, because this sector contributes<br />
significantly to engaging workforce in rural areas<br />
and ensures a fair standard of living for farmers.<br />
Agricultural Consulting Service is present as<br />
service in South Muntenia Region from 1998, in<br />
2010 the Agricultural County Offices being<br />
reorganized into the Agricultural Chambers<br />
County. In the South Muntenia Region there are<br />
seven Agricultural Chambers that perform specific<br />
consulting each county, they being subordinated to<br />
the county councils.<br />
1 University of Agronomic Sciences and Veterinary Medicine of Bucharest<br />
The approaches that agricultural consulting<br />
service makes help to correct actions of farmers<br />
and their information, for progress and to bring<br />
new elements in the work they perform. The<br />
Agricultural Consulting Service is necessary to<br />
increase the decision capacity of farmers and to<br />
improve policy promotion through marketing<br />
activities so that productions can be efficiently<br />
exploited.<br />
MATERIAL AND METHOD<br />
To evaluate the role and contribution that<br />
agricultural consulting service has brought in the<br />
South Muntenia Region, we have reviewed the<br />
annual reports of agricultural county chambers of the<br />
seven counties.<br />
RESULTS AND DISCUSSION<br />
South Muntenia Region is one of the most<br />
important agricultural areas in Romania.<br />
Exploiting at the true value with protecting of<br />
environment can contribute significantly to the<br />
country's economic growth. In the 2009-2011<br />
period, Agricultural Chambers have developed<br />
various information activities and training courses.<br />
In this region over 600 training courses,<br />
qualifications, and instruction classes attended by
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
over 14,000 people were conducted. The large<br />
number of courses is due to absence of<br />
qualification of some farmers in the field,<br />
qualification necessary to access the measures of<br />
National Rural Development Plan. (PNDR). The<br />
lack of specialists in the territory is another<br />
problem that the agriculture is facing and to<br />
prevent this problem, Agricultural County<br />
Chambers organized training courses of instructors<br />
and training of specialists.<br />
Excessive crumbled of agricultural land is<br />
one of the problems that make their exploitation<br />
difficult. Rural population is not yet open to the<br />
idea of land merging and the potential benefits<br />
that may arise, particularly productivity growth.<br />
Due to the action of Agricultural Chambers were<br />
set up: 31 agricultural cooperatives according to<br />
Law no. 566/2004, 3 associations according to<br />
Ordinance 26/2000, 518 individual enterprises and<br />
authorized individuals (PFA), 3 recognized groups<br />
of producers, 2 companies according to Law no.<br />
31/1990 and 7 proffesional associations.<br />
Between 2009 and 2010, the consultants<br />
have noted reductions of the Agricultural<br />
Cooperative numbers, because landowners are<br />
reluctant, but last year the number had risen<br />
because of realizing association benefits. The large<br />
174<br />
number of authorized individuals, individual<br />
enterprises and familial enterprises is due to the<br />
condition imposed by Measure 141 - Financial<br />
support for subsistence farming and Measure 112 -<br />
Setting up of young farmers.<br />
The practical demonstration makes it easy to<br />
understand and then to apply technology or<br />
information transmitted. County Agricultural<br />
Consulting Offices and after 2010, Agricultural<br />
Chambers have conducted 262 demonstration plots<br />
on crop production, most of them being made in<br />
Dâmboviţa County (51.5% of them) and 48<br />
demonstration plots on animal production, 75% of<br />
which were made in the same County.<br />
According to Figure 1, activities of<br />
popularization are: meetings, roundtables and<br />
debates, followed by meetings with members of<br />
target groups. Counties with the most activities of<br />
publicizing are: Dâmboviţa, Teleorman and<br />
Călăraşi. Besides these actions, radio and TV<br />
shows took place, which were intended to inform<br />
farmers about the measures that can be accessed<br />
and about specific seasonal works of certain crops<br />
from area. Most information shows were registered<br />
in Argeş County where only in 2009 were<br />
broadcast over 78 television programs through<br />
local television, Muscel TV.<br />
Figure 1. Activities of popularization development by the Agricultural Chambers<br />
from South Muntenia Region during 2009-2011<br />
Special attention was given and to the<br />
promotion of materials like leaflets, flyers,<br />
brochures and articles in specialized publications.<br />
Consultants from county and local level<br />
were continuously involved in providing expert<br />
advice directly to farmers, particularly those of<br />
small and medium-sized family farms, including<br />
technico-economical services and specialized<br />
services. In addition, it was accorded individual<br />
consulting to interested persons at the county<br />
office, local, telephonic, by e-mail and<br />
correspondence.<br />
Generally, the requests for advice and expert<br />
technical assistance aimed at specific areas of<br />
agro-industry: proper application of technologies<br />
of production, the identification, access and use of<br />
inputs, proper management of production<br />
processes, product marketing, activities in<br />
accordance with specific legislation, government<br />
subsidies and facilities, EU regulations, the land<br />
fund, agricultural life annuity, milk quota and so<br />
on.
Figure 2. Technical assistance given to agricultural<br />
exploitations according to unit size.<br />
From the observations of the last three<br />
years, it was found that the vast majority of those<br />
175<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
who seeking agricultural consultations are small<br />
farms.<br />
The distribution on activity fields of<br />
technical assistance during 2009-2011 was as<br />
follows (Figure 3):<br />
34008 consultations in cereals production field;<br />
15852 consultations in vegetables field;<br />
12950 consultations in horticulture field;<br />
1857 consultations in viticulture field;<br />
19159 consultations in livestock production<br />
field;<br />
14666 consultations in mechanization field;<br />
2756 consultations in economic field;<br />
19120 consultations in juridical field;<br />
20105 consultations in other fields (accessing<br />
European funds, subsidies and so on).<br />
Figure 3. The distribution on activity fields of technical assistance during 2009-2011<br />
It was found that technical assistance<br />
accorded to farmers varies according to farm size<br />
and field of activity in which they performs:<br />
- the cereals cultivation, 79.5% of<br />
consultations was offered to small farms, 14.5% of<br />
medium and 6% of large farms;<br />
- in vegetables field, 90.1% of consultations<br />
was offered to small farms, 9% of medium and<br />
0.9% of large farms;<br />
- in horticulture fields, 97.9% of<br />
consultations was offered to small farms , 1.7% of<br />
medium and 0.4% of the large farms;<br />
- in viticulture fields, 81.4% of<br />
consultations was offered to small farms , 14.4% to<br />
medium and 4.2% of the large farms;<br />
- in zootechnical fields, 92.5% of<br />
consultations was offered to small farms , 6.2% to<br />
medium and 1.3% of the large farms (figure 4).<br />
Practical demonstrations were an important<br />
contribution to acquiring knowledge, therefore<br />
Agricultural Chambers in collaboration with<br />
various research units have conducted 181<br />
demonstrations attended by 2728 people.<br />
Figure 4. Technical assistance granted according<br />
to activity fields and categories of exploitations<br />
Following action taken by specialists from<br />
the County Agricultural Chambers of Agricultural<br />
Consulting and Local Centres, for the<br />
dissemination among the rural population of the<br />
National Rural Development Programme 2007-<br />
2013 and the presentation of measures to be<br />
funded, many farmers were interested to accessing<br />
these funds. The consultants permanently monitor<br />
the potential beneficiaries of EU funds and take<br />
action to support design collectives by professional<br />
training, model projects and exchange of<br />
information.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
The impact of information and publicizing<br />
actions realised by Agricultural Chambers from<br />
South Muntenia Region has led to the following<br />
number of projects (figure 5):<br />
- 61 projects with a total value of 4,644,193<br />
euros, which access 121 measure - Modernisation<br />
of agricultural farms,<br />
- 2882 projects totaling 17,899,500 euros,<br />
which accesses 141 measure - Supporting semisubsistence<br />
farms,<br />
- 853 projects totalling to 10,703,500 euros<br />
which accesses 112 measure - Setting up of young<br />
farmers.<br />
Figure 5. Technical assistance accorded for<br />
development projects to access European funds<br />
Accesing these measures contribute to<br />
adaptation of agricultural exploitations to EU<br />
standards, encouraging the phenomenon of<br />
association, increasing production and improving<br />
quality, increasing the number of farms and their<br />
economic power, improved management and<br />
diversification of activities according with market<br />
requirements.<br />
Restrictive elements<br />
Activities and performances of Romanian<br />
farmers are limited by several factors such as<br />
agricultural economic environment (which is<br />
unstable and less predictable), unbalanced<br />
competitive environment, friendly for retailers and<br />
distributors but unfriendly for farmers, insufficient<br />
profesional training of most managers from<br />
agricultural units in economical and financial area,<br />
a surplus of workforce in agriculture, the absence<br />
of small farms in modern trade networks of<br />
vegetable and animal products.<br />
176<br />
Favorable elements<br />
Supporting small farms contribute to<br />
strengthening competitiveness and maintain the<br />
vitality of rural areas and supply of local markets.<br />
Possibility of accessing European funds to<br />
young farmers is an opportunity to attract them in<br />
the agricultural sector considering the ageing<br />
population which is still active in agriculture, but<br />
also obtaining a decent income.<br />
CONCLUSIONS<br />
The majority of requests for consulting<br />
services come from the small exploitations and<br />
concern to the agro-industry specific fields.<br />
Most demanding areas of specialized<br />
tehnical assistance were given in the field crop<br />
production, accessing EU funds and subsidies and<br />
in the field of animal production.<br />
The partnership between farmers and<br />
agricultural consultants help improve the<br />
agricultural performances and incomes in rural<br />
areas.<br />
The lack of funds and land crumbled are<br />
problems that make difficult farmers activities.<br />
In 2009-2011, in South-Muntenia Region,<br />
were developed 3796 projects to access European<br />
funds with a value totaling over 33 million euro.<br />
Accessing the measures of National<br />
Programme for Rural Development help to adapt<br />
to EU standards agricultural holdings, increased<br />
production and product quality.<br />

INTELLIGENT COMPUTING FOR EVOLVING SYSTEMS<br />
Marilena DONCEAN 1<br />
e-mail: doncean_marilena@yahoo.com<br />
The intermediate results of this study add to specialised, relatively restricted, research focus of the field, which seeks to<br />
ascertain the mechanisms behind modern approaches in intelligent computing for evolving systems, based on theoretical<br />
and practical foundations and considering the fact that we are heading towards a liberal knowledge-based economy. The<br />
knowledge-based economy is a challenge for the future. The mathematical modelling of time-evolving systems is a<br />
method of the future. Due to short decision-making time, ever more companies resort to intelligent systems to assist<br />
managers in making key decisions. In the new knowledge-based economy, the importance of information derives from<br />
the advantages it offers in a deeply competitive society.<br />
Key words: economic decisions, intelligent computing, evolving system, artificial intelligence, fuzzy computing.<br />
Given the existence of numerous<br />
optimisation problems, pertaining to the modelling<br />
of complex processes that unfold over several<br />
periods, each one demanding the optimal solution,<br />
the static perspective can act as a drawback. It is<br />
clear that the sequence of solutions cannot be<br />
determined solely based on the parameters of each<br />
examined period separately and that it is necessary<br />
to identify a series of solutions that optimise the<br />
entire examined process.<br />
Evolving problems, which demand a series<br />
of sequential decisions, are characterised by the<br />
fact that a decision adopted in a certain period has<br />
both an immediate effect, as well as a long-term<br />
effect, influencing other stages.<br />
As is well known, many real problems<br />
require the simultaneous optimisation of several<br />
target functions. Typically, there is no single<br />
solution for these applications. Up until now, in<br />
order to solve such problems, evolutionary and<br />
technical algorithms, proposed as early as 1985,<br />
have been applied. The literature in the field<br />
describes many successful applications, however<br />
the methods based on evolutionary algorithms are<br />
not yet widely available.<br />
Because of the short decision-making<br />
timeframes, increasingly more companies turn to<br />
intelligent systems to assist managers in making<br />
key decisions.<br />
In the new knowledge-based economy, the<br />
importance of information stems from the<br />
advantages it brings to a deeply competitive<br />
society.<br />
MATERIAL AND METHOD<br />
For the purposes of conducting the present<br />
research, I consulted the most recent and important<br />
works of literature in the country and abroad. The<br />
methodology of the research of the paper relies on<br />
the utilisation of methods such as descriptive<br />
analysis, comparative analysis, induction, deduction,<br />
synthesis, comparison, correlation, evaluation, and on<br />
formal and symbolical constructions and solutions<br />
(figures).<br />
Intelligent computing is an area of Artificial<br />
Intelligence, grouping techniques aiming to solve ―illposed‖<br />
problems or those for which formal models<br />
lead to particularly costly algorithms.<br />
Intelligent computing includes the following<br />
main directions of research (Tacu A.P. et al, 2003):<br />
• Neural computing - mainly employed in<br />
solving association problems (classification,<br />
approximation, prediction, etc.), relies on retrieving a<br />
model from examples by means of learning. Its<br />
source of inspiration is the structure and functioning<br />
of the brain.<br />
• Evolutionary computing - mainly applied to<br />
solve problems based on searching for solutions in a<br />
large pool of potential solutions (in particular in<br />
solving optimisation problems). Its inspiration lies in<br />
the Darwinian evolutionary principles.<br />
• Fuzzy computing - used when the data of<br />
the problem (i.e. the relationship between them)<br />
cannot be described accurately and there is a degree<br />
of uncertainty (―fuzziness‖). The basic idea is to<br />
replace the exact values (―crisp‖) with ―fuzzy values‖<br />
described by membership functions.<br />
Each of the three above-mentioned directions<br />
involves alphanumeric processing, requiring a proper<br />
numerical encoding of the problem. On the other<br />
1 Romanian Academy – Iaşi Branch, Gh. Zane Institute of Economic and Social Research, Iasi
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
hand, each of the above directions attempts to<br />
simulate intelligent behaviour, which drives the<br />
presence of the intelligent term.<br />
The fundamental principle behind the<br />
evolutionary and neural computation is to develop<br />
intelligent computation systems starting from the<br />
implementation of simple rules, while the complex<br />
behaviour of these systems deriving in parallel and<br />
interactively the application of these rules. This<br />
bottom-up approach is in contrast with the “topdown”<br />
approach typical of other Artificial Intelligence<br />
approaches.<br />
Neural and evolutionary computing are part of<br />
the broader spectrum of natural computation which<br />
relies on taking cues from natural systems (physical,<br />
chemical, biological, ecological) in order to solve<br />
problems.<br />
The main objective of natural computing is to<br />
develop natural methods of solving ill-posed problems<br />
and problems that are unsolvable by traditional<br />
methods (e.g., solving NP-complete problems in<br />
polynomial time).<br />
In addition to the previously mentioned<br />
components, natural computation includes:<br />
•molecular computing (DNA Computing)<br />
• Membrane Computing<br />
• Quantum Computing.<br />
RESULTS AND DISCUSSIONS<br />
Evolutionary computation provides search<br />
mechanisms, within the framework of solutions<br />
based on the principles of natural Darwinian<br />
evolution.<br />
In order to find the solution, a research<br />
population is used. This population is subject to an<br />
evolutionary process, which involves selection,<br />
crossover, mutation.<br />
Depending on how the population is built<br />
and how evolution is implemented, the<br />
evolutionary computing systems fall into one of<br />
the following categories:<br />
• Genetic algorithms - mainly used to solve<br />
discrete optimization problems. The population is<br />
represented by binary coded states of the space of<br />
the problem (an element of the population is<br />
encoded as a string of bits), and the main operators<br />
are crossover and selection, while mutation<br />
operators have a low probability of application.<br />
Genetic algorithms were initially proposed by<br />
Holland.<br />
• Genetic programming – is used to<br />
develop calculation “models” (simple programs).<br />
The population is represented by programs that<br />
contribute to solving the problem. These tend to be<br />
described as derivation trees of the word that they<br />
represent in the language in which it is written and<br />
not as lines of code; for example, “the expressionprogram<br />
a + b * c” is (+ a (* bc) ). Crossover is<br />
performed by means of random selection sub-trees<br />
from the tree associated with parent programs and<br />
178<br />
performing interchanges. As with genetic<br />
algorithms, the mutation has a limited weight.<br />
Koza is widely regarded as the founder of genetic<br />
programming.<br />
• Evolving strategies - were originally<br />
designed to solve technical optimisation problems,<br />
aiming to solve continuous optimisation issues.<br />
The population consists of elements of the<br />
definition field of the target function. The main<br />
operator is mutation, however recombination is<br />
also employed. Adaptation schemes for control<br />
parameters (self-adaptation) have been developed<br />
for evolutionary strategies. Rechenberg and<br />
Schwefel have made significant contributions to<br />
the development of evolutionary strategies.<br />
• Evolutionary programming - is used both<br />
for the optimisation and the development of certain<br />
computing (automated) structures. The main<br />
operator is mutation. The foundations of the field<br />
were laid by Fogel.<br />
All these methods rely on the simulation of<br />
the evolution of a set (population) of information<br />
structures (configurations or individuals) under the<br />
action of processes similar to those of natural<br />
evolution, namely: selection, mutation and<br />
crossover.<br />
The action of these processes is controlled<br />
by means of a performance function (“fitness<br />
function”), which measures the adequacy each<br />
individual to the environment it belongs to. For<br />
example, when solving an optimisation problem<br />
(maximisation), the “fitness” function is essentially<br />
the target function of problem.<br />
Genetic algorithms are part of the class of<br />
evolutionary computation techniques, being<br />
stochastic search algorithms inspired by natural<br />
selection and genetics. The underlying principle is<br />
that there is a population made up of individuals,<br />
that make up the potential solutions to the problem<br />
and, in metaphorical terms, individuals are asked<br />
to compete against one another for survival. After<br />
evaluating each individual, the stronger ones are<br />
assigned a greater chance of participating in the<br />
reproduction process than the less powerful, which<br />
may not even be involved at all.<br />
Genetic algorithms typically involve the<br />
following steps:<br />
1. Random generation of an initial<br />
population of n acceptable solutions to the<br />
problem, represented by n chromosomes.<br />
2. The evaluation of a suitability function f<br />
(x) for each chromosome x in the population.<br />
3. Creating a new population by repeating<br />
the steps below until the new population is<br />
complete:<br />
a. Selection: select a pair of parent<br />
chromosomes according to their suitability (the
more suitable being more likely to be chosen for<br />
reproduction)<br />
b. Crossover: based on a given crossover<br />
probability parents are crossed with each other to<br />
generate a pair of descendants (if there is no<br />
crossover, descendants are identical copies of the<br />
parents).<br />
c. Mutation: based on a given probability<br />
certain positions are changed, i.e. genes in<br />
descendants’ chromosomes.<br />
4. The generated population replaces at least<br />
in part the old population and the resulting<br />
population is used to go step by step through the<br />
same algorithm.<br />
5. If the stopping condition is reached, the<br />
algorithm ends and retains the best solution in the<br />
current population, which is also the last.<br />
6. If the stopping condition is not reached,<br />
the evaluations at step 2 are resumed.<br />
The outline of genetic algorithms given<br />
above has varied consequences. One issue, as<br />
noted above, refers to creating chromosomes, to<br />
perform the encoding of individuals in a particular<br />
population. Based on the shape chromosomes, the<br />
two basic operators of genetic algorithms are<br />
defined, i.e. combining- crossover and mutation.<br />
The theoretical advances over the past two<br />
decades in the area of artificial intelligence<br />
increasingly suggest the attempt to abandon<br />
traditional ways of approaching and solving<br />
practical problems in various fields not limited to<br />
technical ones (economy, finance, social, etc.). In<br />
contrast to the (logical-symbolic paradigm (with<br />
applications found in intelligent software focusing<br />
on highly complex problems, yet in a strictly<br />
defined field – such as chess for example), the<br />
connexionist paradigm introduces the concept of<br />
neural computation and has given rise to artificial<br />
neural networks (ANN) - which are models<br />
inspired by the human brain structure (Docean G.<br />
and Docean M., 2012).<br />
Figure 1. Neural networks<br />
Artificial neural networks learn to solve a<br />
given problem, developing a memory that is able<br />
to associate a large number of input data sets with<br />
corresponding sets of results or effects. They have<br />
the ability to learn from the examples they are<br />
presented with, without knowing anything about<br />
the mathematical model and solution algorithm<br />
behind the model. Moreover, even if the practical<br />
problem is so complex that does not permit the<br />
179<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
development of a sufficiently coherent<br />
mathematical model (and therefore cannot be<br />
approached by traditional computing means,<br />
regardless of the performance of the computer and<br />
the time available), a properly built artificial neural<br />
network can solve the problem satisfactorily,<br />
provided only there are enough examples of inputoutput<br />
data, which can serve to teach it.<br />
In a broader context, such networks may be<br />
integrated into “artificial intelligence”-type<br />
computational structures, that also draw on other<br />
recent techniques such as genetic algorithms,<br />
evolutionary programming, simulated tempering<br />
and fuzzy systems theory (Beiseln E.P, 1987).<br />
Fuzzy computing allows the handling of<br />
vague concepts that cannot be modelled by exact<br />
mathematical concepts (classic numbers, sets or<br />
functions). Problems in which vague concepts<br />
occur arise in control theory when systems are<br />
nonlinear character and their states can be<br />
described accurately only by means of statements,<br />
which have a degree of ambiguity.<br />
Neural and evolutionary computing are part<br />
of a broader natural computing whose principle is<br />
to draw ideas for problem solving from natural<br />
systems (physical, chemical, biological,<br />
ecological). The main objective of the natural<br />
computing is to develop methods of solving illposed<br />
problems and those that are unsolvable by<br />
traditional methods.<br />
In addition to the previously mentioned<br />
components, natural computation includes<br />
molecular computing (DNA Computing),<br />
computing using membranes (Membrane<br />
Computing) and Quantum Computing. While<br />
the first two lines are already established, the last<br />
three are still in the early stages of development.<br />
From a practical standpoint, worldwide in<br />
the technical field multi-criteria decision analysis<br />
(MCDA) and multi-objective optimisation (MOO).<br />
CONCLUSIONS<br />
The goal of reflecting the true qualities and<br />
structural relations of economic reality demands a<br />
continuous process of development of flexible<br />
economic and mathematical models. The<br />
emergence of new situations from innovative<br />
assumptions marks each time a new step towards<br />
reconciling the model with the reality (the real<br />
objective reflected by the model).<br />
Viewed in terms of the evolution of their<br />
trajectories, intelligent computing for evolutionary<br />
systems has gained in adaptability and flexibility<br />
and have significantly developed their<br />
interdisciplinary focus.

Taking into account the advances of<br />
computing technology, existing software<br />
capabilities and the constant adaptation to practical<br />
requirements, intelligent computing for<br />
evolutionary systems lies at the border of<br />
organisational economics, mathematics and<br />
computing.<br />
The progress made since the emergence of<br />
the first modelling, simulation and optimisation<br />
works up to the present illustrates the constant<br />
concern of specialists to distinguish methods and<br />
paths that are as close as possible to economic<br />
reality in order to improve decision making. Along<br />
these lines, in addition to traditional processes<br />
based on intuition and experience, very modern<br />
scientific decision making methods are required,<br />
with a strong theoretical foundation based on<br />
mathematical methods, while maintaining a<br />
general, practical and realistic focus.<br />
For these purposes, intelligent computing<br />
for evolutionary systems represents an<br />
advanced approach that is a prerequisites for<br />
decision making in a liberal knowledge based<br />
society.<br />

THE PRINCIPLES AND VALUES OF MANAGEMENT ETHICS<br />
Marilena DONCEAN 1<br />
e-mail: doncean_marilena@yahoo.com<br />
The intermediate results of this study complete the rather limited research focus of the field, which seeks to contribute<br />
to elucidating, based on theoretical and practical grounds, the mechanisms underlying the modern practices related to<br />
management principles and ethics values, as we are advance towards a liberal knowledge-based economy. The research<br />
undertaken as part of this study has identified the current need of the Romanian economy for practices in management<br />
ethics. Certainly, in Romania, it is difficult to ensure compliance with ethical standards and relational behaviour, due to<br />
economic and political instability, legal uncertainty, and aggressive government tax policy; nevertheless, in the future<br />
we expect increasingly a return to the traditional values of Romanian merchants, namely: the penchant for honesty,<br />
competence, democratic orientation, rational risk-taking, safe partnerships, and openness to communication.<br />
It is well known that ethics in management is emerging as a new discipline that aims to define the proper conduct of<br />
managers, focusing on what is good, just, fair, and moral in decisions made by managers. Having a good conduct means<br />
observing certain values, which ultimately represent the wellbeing of all people.<br />
Keywords: management, relational behaviour, behaviour, moral judgments, partnership.<br />
Behaviour represents the observable activity<br />
occurring during interaction with one’s<br />
environment. It has been proved that the body<br />
reacts to stimuli, mounting targeted responses. Our<br />
behaviours are determined by what we think and<br />
feel, and are not isolated, but rather they influence<br />
one another, both in the present and throughout the<br />
evolution of human persons. The cognitive<br />
behavioural approach links the cause, thought,<br />
ideas, accompanied by emotional experiences that<br />
trigger a particular behaviour.<br />
Ethics integrates biological and social<br />
factors, being determined by psychophysical<br />
responses to some stimuli, in addition to cultural<br />
factors and features of the social background.<br />
Behaviours are therefore “complex<br />
reactions” integrated and hierarchically organised<br />
according to the characteristics of the set of<br />
stimuli. Any behavioural act is motivated,<br />
regardless of whether sometimes we may not be<br />
aware of why we perform a particular action.<br />
Motivation represents the set of internal<br />
factors that determine behaviour and the<br />
mechanism that explains the effects. Under the<br />
effect of internal and external stimuli, motives<br />
drive the individual into action and support<br />
activities for a particular period of time, against<br />
any obstacles that may arise. They also may cause<br />
the individual to pursue a particular goal or another<br />
and establish a certain hierarchy of possible goals.<br />
RESEARCH ISSUES AND METHOD<br />
Management ethics seeks to understand and<br />
accept certain stages and behaviours in the decisionmaking<br />
process, assessing them in terms of moral,<br />
therefore focusing on the moral side of management<br />
practice.<br />
Ethics in management is a field of applied<br />
research targeting the moral conduct of managers,<br />
the views, aspirations, skills, principles, etc.<br />
underlying daily decision-making. The scope of<br />
management ethics is very broad, as it includes a<br />
wide array of moral issues often occurring in<br />
organisations’ activities, at levels of management<br />
functions (planning, organisation, management,<br />
coordination, control) and firm functions (R&D,<br />
production, commercial and marketing, financial<br />
accounting, human resources).<br />
Below, we present a brief inventory of some<br />
issues related to perceptions of ethics within an<br />
organisation (table 1).<br />
The list could go on, but we believe that the<br />
essence of ethics must consist in training and<br />
developing moral competence in managers, i.e. a<br />
person's ability to understand moral behaviour and<br />
actions, to implement them in compliance with<br />
existing moral law.<br />

One should not neglect the statement that any<br />
practical moral is both worse and better than the<br />
society. Worse as it contains remains troublesome<br />
remnants or relics, and better owing to its progressive<br />
elements that help us adapt to the future.<br />
Essentially, management ethics can be defined<br />
as the study of the manner in which decisions<br />
affect people and social groups, areas in which<br />
rights and duties are defined, and the rules to be<br />
observed by decision-makers in the organisations<br />
that they lead.<br />
RESULTS AND DISCUSSIONS<br />
One question that managers often ask<br />
themselves with respect to a situation and the<br />
action-based interpretation of the situation is What<br />
should I do? The analysis of this question reveals<br />
that a moral (ethical) position is defined as follows:<br />
- it is a problematic situation, as highlighted by the<br />
question itself;<br />
- it is a personal situation as the subject of the<br />
interrogative sentence is in the first person,<br />
singular;<br />
- it is an action (or behaviour)-driven situation<br />
because the object refers to a manner of<br />
performing or acting;<br />
- it is a normative statement as indicated the<br />
presence of the deontic factor in the question;
- it is a matter of value (choice) as the answer to<br />
the question involves the assessment of<br />
alternatives as goals and solutions;<br />
- it is a significant event (semiotics) as the answer<br />
to a question must be meaningful in relation to<br />
the problem and intelligible for the one judging<br />
the action.<br />
Most times, it is particularly difficult, even<br />
in the simplest cases, to distinguish between<br />
ourselves and the others, between benefits and<br />
obligations.<br />
The voice of conscience calls on us not to be<br />
evil, cowardly, selfish or disingenuous. Sometimes<br />
one must persevere in seeking the paths of justice<br />
and of truth, which demand on the one hand a<br />
measure of equality, and on the other hand a<br />
degree of achievement of one’s obligations, duties<br />
or individual preferences. One must therefore take<br />
decisions particularly aimed at efficiency and<br />
effectiveness.<br />
Peter Drucker stated that the manager must<br />
consciously take on responsibility for the common<br />
good and to rein in personal interest and authority<br />
when their exercise would be contrary to<br />
individual freedom and the common good. This<br />
conservative, demanding vision stems from the<br />
view of a social order based on a moral purpose, in<br />
which accepting responsibilities and obligations<br />
justifies the claims to particular rights.<br />
Knowing that which a person believes to be<br />
moral or ethical does not necessarily mean that<br />
such behaviour is compatible with such<br />
knowledge. As shown in figure 1, ethical<br />
behaviour is a function of judgments resulting<br />
from ethical reasoning, as a sum of individual and<br />
organisational factors.<br />

Related to the above issues, Garabet<br />
Ibrăileanu argued that most false judgments on<br />
human matters are due to moral shortcomings<br />
and not to intellectual weakness, because man<br />
183<br />

tends to lose sense of reality on his moral side,<br />
rather than on the intellectual.<br />
A manager is able to make better decisions<br />
and choices as long as these match or are shared<br />
with those of his business partners.<br />
Ethics in partnerships is grounded in two<br />
fundamental principles:<br />
a) the supremacy of man;<br />
b) achieving goals or common good by<br />
observing moral principles.<br />
Any partnership is primarily based on trust,<br />
on moral and predictable behaviour and the<br />
partner’s capacity to cope with crisis.<br />
Creating strong partnerships involves the<br />
following ethical qualities that both part must<br />
share:<br />
• Responsibility - each member must take<br />
responsibility and confront difficulties and<br />
opportunities head on;<br />
• Integrity - members should follow their<br />
commitments and engage in an authentic way;<br />
• Openness - each member must express<br />
his/her opinion openly, without causing any harm<br />
or offence to another;<br />
• Synergy - combining the talents and<br />
creativity within the partnership, in order to expose<br />
new ideas and ways of achieving goals.<br />
The introduction of ethics as a priority in<br />
management training can be achieved in one of the<br />
following main ways:<br />
• a specific policy or a code of ethics;<br />
• a committee made up of board members;<br />
• a management development program<br />
which incorporates relational ethics.<br />
Segments of behaviour are viewed as<br />
forming a “torrent of ethics” that integrates such<br />
the motivation of human actions.<br />
Behaviour depends only on stimulation,<br />
whereas ethics also involves regulation. Ethics<br />
reaches different quality levels, through learning,<br />
as a result of the interactions between the body and<br />
the natural and social environment.<br />
Thus, the identification and communication<br />
of one’s principles and values one to identify and<br />
address sensitive situations even before they occur.<br />
Consequently, one can view the integrated role of<br />
the manager as a mediator between the interests of<br />
investors and employees. The manager must<br />
exhibit sound ethics and morals, especially in<br />
tackling problems and in decision making under<br />
sensitive crisis situations.<br />
1. Ethical language – below are listed some<br />
benchmarks that cause a management decision to<br />
be ethical:<br />
• legality, justice;<br />
• the search for truth;<br />
• fairness, impartiality;
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
• honesty and respect for people;<br />
• usefulness for the company;<br />
• first and foremost to do no harm;<br />
• getting involved, taking actions when one enjoys<br />
responsibility.<br />
A management decision is easier to make<br />
and assume if one applies a structured process to<br />
analyse the reasons for and against a particular<br />
solution, as follows:<br />
- short-term profit versus long term gain;<br />
- fairness, justice versus mercy;<br />
- truth versus loyalty;<br />
- individual versus community, the collective;<br />
- the better against the good;<br />
- consensus against compromise;<br />
- risk-taking versus personal peace of mind.<br />
In management decisions, less well does not<br />
necessarily mean bad and much better is not<br />
always well.<br />
CONCLUSIONS<br />
In conclusion, we reach the following<br />
postulates, which summarise most of the issues in<br />
management ethics:<br />
1. Without ethics there is no future for a<br />
manager, partnership or the present-day society.<br />
2. In business, management ethics above all<br />
refers to the moral of the use of money.<br />
3. Progress depends more on the practice<br />
and conduct of ethics and rather than on its mere<br />

CONCEPTUAL ANALYSIS OF HUMAN RESOURCES<br />
IN THE CONTEXT OF KNOWLEDGE<br />
Alina Petronela HALLER 1<br />
e-mail: hallalina@yahoo.com<br />
The management activity of human resources has evolved along with economy and society. Everything that<br />
changes involve influences the way of administrating human resources. Our analysis wishes to be a theoretical analysis<br />
of the main specific concepts of the activity of human resources management, starting from that of management of the<br />
personnel and ending with that of international strategic management of human resources. The concept evolution we<br />
will refer to is incurred by both a huge information flux and the economic liberalization and globalization. These<br />
phenomena have created and consolidated dependencies, and in a knowledge-based economy and society, the<br />
redefinition, adaptation and consolidation of the main economic and social processes is absolutely necessary.<br />
Key words: knowledge economy, economic liberalization, human resources<br />
The more liberal the economy grows, and<br />
the more pieces of information it accumulates, the<br />
more unpredictable becomes the way to<br />
administrate the personnel. Internationalization is<br />
decisive for an effective management of human<br />
resources, a necessary aspect for the integration in<br />
the current global economic context.<br />
According to Encyclopaedia Britannica,<br />
knowledge doubles in just a few years, which leads<br />
to unimaginable changes in all the fields, including<br />
economy and society, the labour market being no<br />
exception.<br />
The management of human resources is<br />
defined as the totality of decisions, activities and<br />
practices that influence the nature of the<br />
relationship between organization and employees<br />
(Beer M. et al., 1984).<br />
The management of human resources is a<br />
vital function of organization, it involves all<br />
employees and needs a long run strategy that<br />
should have in view the traditional practices of<br />
human resources administration, the changes in the<br />
internal and external milieus of the company, so<br />
that the latter could take the most advantageous<br />
position on the market. Michael Poole thinks that<br />
the theoretical basis of the management f human<br />
resources is a combination of multi- and<br />
interdisciplinary elements (Poole Michael, 2000)<br />
and it interferes with disciplines like economy,<br />
occupational psychology and sociology.<br />
More and more managers admit that the<br />
personnel problems are increasingly difficult. The<br />
companies are forced to adapt themselves to a mix<br />
of organization cultures and personalities, an<br />
aspect that is not easy at all.<br />
The management of human resources means<br />
more than performing a function or make business.<br />
This is an activity with an impact upon the<br />
employees, upon the activities that they perform<br />
and, above all, upon the individual and the<br />
organization’s results.<br />
MATERIALS AND METHODS<br />
This paper is based on scientific papers<br />
acknowledged in the management field. It has a<br />
profound theoretical and applied nature and our<br />
intend is to develop a theoretical vision with<br />
applicability in the current economic period based on<br />
knowledge.<br />
RESULTS AND DISCUSSION<br />
From personnel management to strategic<br />
international management of human resources.<br />
Conceptual notions<br />
Over the last century, the human resources<br />
management has been submitted to important<br />
modifications. In Taylorism, human resources<br />
management was focused on the programmes of<br />
personnel selection and remuneration, with a view<br />
to controlling and stimulating the productivity of
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
the performing employees (It is more than<br />
necessary to state that the Taylorism-inspired<br />
management, though obsolete now, is much<br />
utilized. Many of the organizations that make the<br />
financial earning their main objective, if not the<br />
only one, resort to Taylorism theory and principles<br />
that can offer short and medium term advantages.).<br />
The dynamics one can analyse from the<br />
beginning of the 1900s to now has led to a<br />
modification of the conceptual notions. For<br />
instance, the concept of personnel management<br />
was a quite functional label until the 1980s; after<br />
that, the concept of human resources management<br />
started to be used. Now, in a knowledge based<br />
society, while the markets are characterized by a<br />
quasi-total degree of liberalization, other two<br />
concepts find their place in economic theory: the<br />
strategic management of human resources and the<br />
strategic international management of human<br />
resources. They reflect reality in a much faithful<br />
way, in its complexity and in accordance with the<br />
modifications brought forth by the economic<br />
openness. We will briefly analyse, in the<br />
following, these four concepts that characterize the<br />
activity of human resources management.<br />
The personnel management has a<br />
perspective limited to what happens in the<br />
organization, summing up traditional activities,<br />
like recruitment, selection and motivation, the<br />
decisions are made by the top management, work<br />
is individual, and the work atmosphere is<br />
confrontational.<br />
The human resources management has a<br />
more complex perspective. Beyond the already<br />
traditional activities, it includes, among other<br />
things, practices that are meant to solve problems<br />
related to environment, to professional and<br />
intellectual development, occupational safety and<br />
health. The human resources management includes<br />
operational and strategic activities; thus the<br />
orientation of decisions covers, from a temporary<br />
point of view, the short, medium and long run.<br />
Furthermore, the influence of internal factors<br />
(employees, material and financial resources,<br />
technologies and equipments, etc.) is analysed as<br />
well. While the personnel management only aims<br />
at attracting, maintaining and motivating the<br />
employees, the human resources management also<br />
purposes to raise competitiveness, profitability, the<br />
market share, to target new market niches, to<br />
obtain competitive advantages, to stimulate<br />
innovation, creativity, flexibility, to get over<br />
conflicts. Recruitment, selection and motivation<br />
remain fundamental activities in the human<br />
resources management, very important in order to<br />
reach the objectives.<br />

As the macroeconomic processes developed,<br />
and economic liberalization brought forth new<br />
opportunities of development and progress, a new<br />
concept appeared, that of strategic management of<br />
human resources.<br />
Strategic management of human resources<br />
represents a combination of very complex actions<br />
that, by the agency of the activities, policies and<br />
practices that are used, integrate and connect with<br />
each other the departments, the workstations,<br />
subsidiaries and branches of the organization. The<br />
purpose is to use the human resources as efficiently<br />
as possible, for the company to reach the strategic<br />
objectives. The strategic management of human<br />
resources is extended beyond the organizational<br />
milieu. Companies modify their strategy in the<br />
periods of crisis or redefine it by drawing a new<br />
plan for their maintenance on the market, for their<br />
growth, adaptation and profitability. Social<br />
pressure determines the organizations to make<br />
decisions and to act in a more responsible way.<br />
This social pressure is exerted from the<br />
organization’s outside milieus, by the partners, the<br />
clients, the providers, the competitors, and from<br />
the inside milieu, by the employees, the<br />
shareholders, the investors.<br />
The internal characteristics (like culture,<br />
work flexibility, the nature of the business) and the<br />
external ones (like the economic circumstances,<br />
the technical-scientific progress) determine the<br />
organizational necessities, whose accomplishment<br />
needs time and a strong relation between the<br />
activities of human resources and the operational<br />
ones.<br />
Economic liberalization created the<br />
conditions for the introduction of the concept of<br />
competitive management of human resources,<br />
taking into consideration the features of the
internal and external milieus. The specific<br />
characteristics of the internal milieu are the<br />
consequences of those coming from the external<br />
milieu, or, in other words, the response to what<br />
happens in economy and in society.<br />
As soon as competition intensifies, appears<br />
the question related to the factors that help the<br />
society, the economy and its organizations to adapt<br />
themselves to fast changes in a competitive<br />
environment. One of these factors is the flexibility<br />
of work. A deregulation of the labour market is<br />
made, first of all, by the pressure of the<br />
multinational companies. All organizations,<br />
regardless of their object of activity, size or field of<br />
activity, are forced to adapt their practices and<br />
activities, including the personnel ones, to the<br />
general tendencies.<br />
Another particularly important factor is<br />
culture. Each economy has its culture, just like<br />
each organization, and this influences management<br />
too. One of the main changes due to the<br />
internationalization of activities is the adaptation of<br />
the human resources management to different<br />
culture, by conceiving a strategy that takes into<br />
consideration cultural particularities that interfere<br />
within the same organization. The more a company<br />
is globalised and diversifies its field of action,<br />
product and activity portfolio, the more diversified<br />
grows the personnel, and its main characteristic<br />
feature becomes the intercultural one, and that<br />
requires great efforts of adaptation. Many times,<br />
being intercultural was a major obstacle in the<br />
company’s development. Cultural aspects deemed<br />
minor brought forward the failure of companies on<br />
different markets. For this reason, even if the<br />
economic conditions recommend one market, the<br />
entrance only takes place after feasibility studies<br />
were made, taking into consideration the specific<br />
cultural elements as well. For instance, it is wellknown<br />
that about 75% of the joint-ventures fail<br />
from the start-up period (the first 5 years of<br />
working) because of cultural maladjustment.<br />
Respecting the culture of the employees and<br />
adapting different cultures together eliminate many<br />
obstacles. To harmonize different cultures involves<br />
knowing the colleagues’ language, or a common<br />
language, respecting the religion, ethnicity,<br />
customs of the employees and of the clients as<br />
well. The organization forms its own culture,<br />
according to the employees’ human and cultural<br />
characteristics and to the socio-economic<br />
particularities of the states where the company<br />
works or sells products. There is no company that<br />
would not develop an organizational culture.<br />
Culture determines the manner in which activities<br />
(labour) take place and decisions are made.<br />
187<br />

Organizational culture includes the<br />
collective standards of thought, of attitude, values,<br />
convictions, norms and customs existing in an<br />
organization (www.elfconsulting.ro), i.e., visible<br />
elements (common behaviours and language,<br />
rituals and symbols) and less visible elements<br />
(perceptions, representations about the values of<br />
the organization, myths, empiric standards about<br />
the meaning of adequate work and conduct). A<br />
strong influence on the organizational culture<br />
comes from the management style, the decisionmaking<br />
style, formalism, the organizational<br />
pattern, the policies, the know-how and all that<br />
supports a certain type of work and behaviour. The<br />
organizational culture analyses the values and<br />
principles of the organization and introduces the<br />
company into a chain of tacit significances that<br />
grant specifically human meanings to all<br />
organizational activities and processes. Culture is<br />
the most important resistance factor in any process<br />
of change, regardless of its scope. Organizational<br />
culture is compared with the personality of a<br />
human being: it is hard to build, and even harder to<br />
change. The difference is that organizations, in<br />
order to survive, must change<br />
(www.elfconsulting.ro). If people do not accept<br />
change, and the management cannot convince<br />
them of its necessity, the organizational<br />
equilibrium becomes rather fragile.<br />
Under the conditions of economic<br />
liberalization, the traditional approaches are<br />
partially abandoned for an effective management<br />
of human resources to be reached. One of the<br />
factors that deeply modified the type of<br />
organizational management, the economy as a<br />
whole, society, the life styles and mentalities, is<br />
technology (equipments, machines, methods of<br />
utilization, know-how). All organizations,<br />
regardless of their field of activity, of their size,<br />
form of property, of the markets they work on, use<br />
technology. Technological development (physical<br />
components and processes) takes place in an<br />
increasingly faster rhythm and submits the<br />
organizations to a strong competitive pressure,<br />
determining them to acquire and implement the<br />
newest installations, equipments, and working<br />
methods. Along with the technological boom, the<br />
labour market has changed, as the technical capital<br />
has different consequences upon the human<br />
resources field, according to its properties: it<br />
creates job opportunities (if the implementation<br />
involves the employment of persons able to<br />
manipulate it), it does not modify the number of<br />
workplaces (the employees are able to work with<br />
the elements of the technical capital), it reduces the<br />
number of workplaces (the technical capital<br />
replaces the labour force). The technologies that
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
replace the labour are investments in productivity.<br />
These investments, on the medium and long runs,<br />
reduce costs and, once they are introduced,<br />
contribute in raising the productivity, justifying the<br />
financial effort to acquire the latest technological<br />
capital.<br />
The new technologies require methods of<br />
utilization involving abilities and knowledge that<br />
the employees do not have. The personnel, in order<br />
not to lose their job, must take retraining or<br />
development courses. If a few decades ago, an<br />
employee could use the knowledge he had<br />
acquired in school all over his active period, today<br />
this is not possible any more. The training periods<br />
are more and more frequent. The young employees<br />
easily accept the idea of continual professional<br />
development, unlike the older ones, who do not<br />
have the same openness to changes and, therefore,<br />
are a vulnerable segment of the labour market.<br />
Beyond the fact that the labour market demands<br />
persons that are open to change and easily<br />
adaptable, it also requires people whose training is<br />
a complex ones, given that skills, knowledge and<br />
abilities are limited.<br />
Dexterity is not any more an employee’s<br />
main quality. Physical work is replaced with<br />
technology. Sometimes, this means the work of<br />
hundreds of people. Technology eliminates the<br />
workplaces of people with low-qualification and of<br />
those who perform mechanical activities, who do<br />
not manage to get out of the old patterns and adapt<br />
to new realities. The positive effect on the labour<br />
market is the reduction of the unemployment rate<br />
among the highly qualified persons, but there is<br />
also a negative effect, easy to anticipate, i.e. the<br />
raise of the unemployment rate among the persons<br />
who do not accept the idea to take training or retraining<br />
courses in the professions that the market<br />
demands at a certain moment.<br />
The introduction, on a large scale, of the<br />
new technologies, destroys the organizations’<br />
hierarchies, the distances between managers and<br />
employees, drawing thus the framework of a<br />
higher quality management and production. Under<br />
the impact of technologies as well, the<br />
organizational patterns become more dynamic and<br />
more flexible.<br />
Another tendency manifested under the<br />
influence of technology, especially the<br />
communicational one, is the transfer of work from<br />
office home, the movement of company<br />
headquarters to less congested areas, cheaper from<br />
the point of view of the costs of dues and locations,<br />
i.e. peripheral or rural areas. Furthermore, the<br />
internet and the information programmes allow an<br />
effective administration of the stocks and facilitate<br />
the relationships with the providers, the clients and<br />
188<br />
the distributors, create possibilities to sell the<br />
products on markets under the form of electronic<br />
trade, whose importance is continuously rising, and<br />
allows the performance of different activities<br />
outside the organization’s headquarters.<br />
Another factor modifying the way in which<br />
the human resources management is made is<br />
demography. The population growth and the<br />
increasing life expectancy determine the increase<br />
of the segment of active population and of the one<br />
of inactive population. The latter should be backs<br />
up by the work and efforts of the persons able to<br />
work. For both men and women, the active period<br />
has increased and the general tendency is to<br />
prolong it, to different ages from one country to the<br />
other, according to the economic conditions and to<br />
the demographic indicators. The elder employees<br />
are regarded as resisting change, especially when it<br />
comes about implementing new programmes and<br />
technologies, or about physical mobility, but this is<br />
only partially true. The employees in the second<br />
half of their active period are often more<br />
productive than the young ones, due to their<br />
experience, perseverance, knowledge, capacity to<br />
identify themselves with the company’s values,<br />
and loyalty to the organization. Knowledge and<br />
experience are fundamental factors, which<br />
contribute to obtaining productivity pluses. More<br />
and more frequent are the situations in which the<br />
organizations choose collaboration with mature<br />
persons, even persons who are theoretically not in<br />
the working field any more, in order to benefit<br />
from their experience and knowledge.<br />
The young and well-trained employees are<br />
usually proactive, and succeed in managing alone<br />
their careers, without making the employer<br />
responsible for this aspect. The proactive attitude is<br />
appreciated by and very helpful fro the<br />
organization, but there is a high risk for these<br />
persons to leave the company as soon as they find<br />
a new opportunity on the market; and opportunities<br />
often come from the competing companies.<br />
Society also changes, in its turn, and thus<br />
influences the labour market. The women’s role<br />
has modified. If, at the beginning of the last<br />
century, women were housewives and their only<br />
obligation was to take care of the house and of the<br />
children’s education, after World War II they had<br />
to enter the labour market. Today, women are<br />
educated, ready to work and to act. Furthermore,<br />
women proved their qualities in management keypositions,<br />
with very good results. Unfortunately,<br />
tendencies of change are notices in relation to<br />
family too. There are more and more single-parent<br />
families or families where both partners are first of<br />
all oriented towards careers. In the case of singleparent<br />
families, most of the times women with
children, the adult finds hard a balance between the<br />
responsibilities he/she has home and the ones<br />
he/she has at work, especially that the<br />
organizations demand loyalty and time spent at the<br />
workplace, more than fulltime. In the case of<br />
families where both partners are focused on career<br />
development, or there are no children, or their<br />
growth and education are delegated to other<br />
persons, a very visible aspect in the developed<br />
economies, where the age pyramids is reversed.<br />
The developed countries face an acute deficit of<br />
young population, translated by a deficit of active<br />
population in the future.<br />
Tightly related to the concepts of strategic<br />
management of human resources and competitive<br />
management of human resources is the one of<br />
international management of human resources. The<br />
concept develops naturally in a competitive,<br />
dynamic, volatile economy, where frontiers, in<br />
they exist, are fragile. The great advantages of<br />
economic liberalization are, among others, the<br />
penetration on new markets, the prolongation of<br />
the cycle of life of products, the acceleration of<br />
amortization, the increase of the turnover and of<br />
profit. The international management of human<br />
resources involves knowledge and the adaptation<br />
to the conditions, society and culture on third<br />
markets. What makes the difference between the<br />
international management of human resources and<br />
the personnel management is the complexity of the<br />
activities performed on markets with different<br />
characteristic features, by active multinational<br />
teams, under the umbrella of the same<br />
organization.<br />
The strategic international management of<br />
human resources, another relatively recent concept,<br />
includes the activities, policies and functions of<br />
administration of human resources, achieved as a<br />
result of the strategic activities of the organization,<br />
which reflect upon the objectives to reach on the<br />
international markets (Schuler R., 2000). This<br />
concept includes all the other concepts we referred<br />
to, being the most complex of them all. Its<br />
definition resembles the one of the management of<br />
human resources in the internal context, but allows<br />
the analysis of some connected factors, specific to<br />
the international markets. (Michael P., 2000)<br />
thinks that the international strategic management<br />
of human resources is not at all revolutionary, but<br />
bring the personnel function on the foreground of<br />
the organization’s preoccupations. Man is the most<br />
important link. Human resources are reconsidered,<br />
and the idea to label it as a component of the<br />
capital is given up. Hierarchies disappear, and so<br />
do prejudges, and the managers are involved<br />
together with the employees in the productive<br />
activity. The current characteristics of the human<br />
189<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
resources management reflect the national,<br />
regional and global facets of competition and<br />
technological and innovation development.<br />
CONCLUSIONS<br />
In this paper, we followed the characteristic<br />
concepts of the activity of human resources<br />
management, from the simplest to the most<br />
complex one. The current management of human<br />
resources is also associated other relatively new<br />
concepts, like: the talents management, the<br />
knowledge management, the performance<br />
management, the rewarding management and<br />
probably many others, resulted from the necessity<br />
to analyse as adequately as possible the processes<br />
taking place in a company. In a dynamic,<br />
competitive economy, based on knowledge,<br />
improperly called a knowledge economy (let us not<br />
forget that evolution is conditioned by knowledge.<br />
Knowledge has accompanied us from the very<br />
beginnings. Today we go through a period<br />
characterized by two major crises, a moral and a<br />
spiritual one, and by a decrease at the level of<br />
consciousness that goes together with an<br />
unprecedented progress at the level of knowledge),<br />
the very way of administrating the personnel is<br />
modified too, a fact that we have demonstrated by<br />
focusing on the determining factors.<br />

The tourist area organization refers to the split of the large territory in relatively homogenous areas from the perspective<br />
of the tourist potential and activities, by inventorying and analyzing all the components of the tourist potential: natural<br />
potential, anthropic potential, accommodation infrastructure and technical infrastructure. The assessment of the natural<br />
potential refers to the analyses of the natural environment, of the existing protected areas, and also of the therapy<br />
factors. The anthropic potential can be analyzed by identifying the historic monuments of national interest, the public<br />
museums and collections, arts and folk traditions, and also the shows and concerts institutions. The assessment of the<br />
accommodation infrastructure takes into account the analyses of the tourist units, the treatment and recreation<br />
structures, of the infrastructure necessary for organizing conferences, and also of the sky path and of the cable-transport<br />
installations, of the public transport and telecommunication infrastructure. In this study the author presents the tourist<br />
organization of the Neamt County by developing and up-dating the study carried out at national level by The Tourist<br />
Department during 2005 – 2007. The finality of the current study represents the drawing out of Neamt County’ maps,<br />
on communes, which to highlight their evaluation from a natural and anthropic perspective, and also by taking into<br />
account their accommodation and technical infrastructure. According to their inventory, there have been identified the<br />
tourist area of Neamt County (Ceahlău – Bicaz, Piatra – Neamţ, Târgu – Neamţ, Cheile Bicazului – Hăşmaş), and also<br />
the new tourist sub-zones (Lacul Izvorul Muntelui, Valea Tarcăului, Valea Muntelui şi Roman).<br />
Key words: tourist area, natural potential, anthropic potential, accommodation, infrastructure<br />
The delimitation of the tourist areas and subareas<br />
proves to be a very benefic work instrument<br />
for creating a mid-time tourist development<br />
strategy for Neamţ County. The tourist zoning<br />
refers to the division of a large area into smaller<br />
areas relatively homogeneous from the point of<br />
view of the tourist potential and of tourist<br />
activities. This process is carried on by<br />
inventorying and analyzing all the elements of the<br />
tourist potential: natural potential, anthropic<br />
potential, accommodation infrastructure and the<br />
technical infrastructure.<br />
In the specialty literature regarding the<br />
tourist zoning of Neamţ County, there are being<br />
mentioned only the well-known tourist areas<br />
(Ceahlău – Bicaz, Târgu – Neamţ, Cheile<br />
Bicazului – Hăşmaş, Piatra – Neamţ), without<br />
being highlighted the tourist sub-zones generally<br />
developed after 2000 and whose accommodation<br />
and technical infrastructure is currently being<br />
developed (Izvorul Muntelui Lake, Valea<br />
Tarcăului, Valea Muntelui and Roman).<br />
MATERIAL AND METHOD<br />
The base for this zoning process are the<br />
methodology and the tourist development criteria<br />
used for evaluation in Romanian by the Ministry for<br />
Small and Medium Size Enterprises, Commerce,<br />
Tourism and Liberal Professions (Romanian<br />
Abbreviation - MIMMCTPL) in 2007.<br />
For the tourist zoning of Neamţ County, the<br />
evaluation criteria have been adjusted and the<br />
information up dated at the level of 2011 (excepting<br />
the technical infrastructure for which the information<br />
is not up-dated).<br />
For the evaluation and the ranking of the<br />
administrative and territorial units (communes) it has<br />
been chosen the method of the analysis trees<br />
according to criteria and sub-criteria, having as<br />
starting points the components of the county’s tourist<br />
attributes. The appreciation level has been assigned<br />
through a share from a total of 100 points as it<br />
follows: natural potential – 25 points, anthropic<br />
potential - 25 points, tourist specific infrastructure –<br />
20 points, technical infrastructure– 30 points.<br />
The 25 points offered to the natural potential<br />
have also been distributed to the natural environment<br />
(position on relief levels – maximum 4 points,<br />
geomorphology - maximum 1 point, vegetation:<br />
maximum 1 point, fauna – maximum 1 point,<br />
hydrographic elements – maximum 1 point and
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
landscape – maximum 2 points), protected areas<br />
(Natura 2000 SCI/SPA Network, Bird Life<br />
International Network and so on – maximum 5 points)<br />
and the natural and therapeutic factors – tourist<br />
resorts from the category I-IV – maximum 10 points<br />
(4, 2008).<br />
The points for the anthropic potential were<br />
assigned as it follows: historic monuments of national<br />
interest (archeology, architecture, public and<br />
memorial monuments) – maximum 8 points,<br />
contemporary architecture, museums and public<br />
collections – maximum 9 points, folk art and customs<br />
(festivals, markets, folk handcrafts and traditions) –<br />
maximum 4 points, and also shows and concerts<br />
institutions (folk groups, orchestras, and so on) –<br />
maximum 4 points. The up-dating of the information<br />
regarding the anthropic potential of the county was<br />
made according to the Annex to the Ord. no.<br />
2.361/2010 for the approval of the Annex no. 1 to<br />
Ord. 2.314/2004 regarding the approval of the updated<br />
list of historic monuments, and of the list of<br />
disappeared historic monuments (3, 2010). It was<br />
also used The Museums Guide in digital format as<br />
conceived by Institutul de Memorie Culturală (The<br />
Cultural Memory Institute) (7, 2011), up-dated with<br />
the information found on the official sites of the local<br />
councils (internet).<br />
To the specific tourist infrastructure was<br />
offered 20 points, being taken into account 5<br />
components: type of accommodation units –<br />
maximum 10 points, treatment structures – maximum<br />
2 points, sky path and on-cable transport installations<br />
– 2 points, recreation installations – 2 points,<br />
infrastructure for conference, meetings and<br />
exhibitions – 4 points. Concerning the<br />
accommodation infrastructure, there have been taken<br />
into account only those units certified by The National<br />
Authority for Tourism (the Romanian Abbreviation -<br />
ANT), the data being up-dated in 2011 by means of<br />
both the list of the classified tourist accommodation<br />
set up by The Ministry of Regional Development and<br />
Tourism (11, 2011), and the specialized sites<br />
(internet). Also, there have been considered only the<br />
treatment structures approved by The Health Ministry<br />
and the sky path and the on-cable transport<br />
installations homologated by ANT, respectively by<br />
The State Inspection for the Control of the Tanks,<br />
Under-Pressure Recipients and Lifting Installations<br />
(the Romanian Abbreviation - ISCIR).<br />
For the assessment of the technical<br />
infrastructure, there have been considered three<br />
components: access and transport infrastructure<br />
(maximum 16 points), town infrastructure – the supply<br />
with common household public services (maximum 9<br />
points) and telecommunication infrastructure –<br />
electronic communication services (maximum 5<br />
points).<br />
The primary data base was processed in Excel<br />
files, and there has been drawn the county map on<br />
communes for simplifying the analyze of the results.<br />
The points accumulated by each commune were<br />
shared on different intervals, each of them being<br />
drawn with a different intensity.<br />

RESULTS AND DISCUSSIONS<br />
The assessment of the natural potential<br />
For the analysis of the county’s natural<br />
potential, if we take into account the natural<br />
environment of the communes, then, the presence<br />
of the two national parks – The National Park<br />
Cheile Bicazului – Hăşmaş and Ceahlău National<br />
Park and Vânători-Neamţ Natural Park (2, 2007),<br />
of the 12 sites of communitarian interest (5, 2007)<br />
and birds and fauna protected areas within Natura<br />
2000 Network (6, 2007) and BirdLife International<br />
(8, 2011), and also numerous reservations and<br />
natural monuments of local interest (Tanasă L.,<br />
2010), to which there is added information<br />
regarding the assessment of the therapy natural<br />
factors existing in the county (2 tourist resorts of<br />
local interest – Durău and Bălţăteşti, ranked at the<br />
3 rd category, respectively 2 localities with<br />
recognized natural factors – Oglinzi and Neguleşti,<br />
ranked at the 4 th category ), we obtain Figure 1,<br />
which offers us a relevant image on the natural<br />
potential on communes within Neamţ County (fig.<br />
1). In the assessment of the natural resources on<br />
communes, the minimum score is assigned to<br />
Oniceni commune (3 points), and the maximum<br />
one to Ceahlău commune (18 points).<br />
Figure 1 The evaluation of Neamţ County<br />
natural potential<br />
Also, the communes that obtained more than<br />
14 points out 25 worth being taken into account:<br />
Ceahlău, Bicaz, Agapia, Bălţăteşti, Bicaz-Chei,<br />
Bicazu Ardelean, Crăcăoani, Dămuc, Gârcina,<br />
Pipirig, Tarcău and Taşca. For these communes the<br />
main strong points are the special natural<br />
environment, the landscape and the existence of<br />
the protected areas. A good score, between 11 –<br />
14 points, is obtained by the communes situated in<br />
the mountain and sub-Carpathian areas, but on<br />
their territory do not exist either recognized<br />
protected areas (Alexandru cel Bun, Borca,<br />
Pângăraţi, Piatra Şoimului and Poiana Teiului), or<br />
the hydrographic and the hunting potential are<br />
more reduced (Târgu-Neamţ, Brusturi, Răuceşti).
An average score, between 7 – 10 points, is<br />
obtained by the other communes located in the<br />
mountain area (Farcaşa, Grinţieş and Hangu), and<br />
also by the communes where sub-Carpathian relief<br />
is preponderant (Petricani, Grumăzeşti,<br />
Ghindăoani, Bodeşti, Negreşti, Dobreni, Piatra-<br />
Neamţ, Borleşti, Girov and Tazlău). In the same<br />
segment are situated the communes/localities along<br />
the meadow of Siret river (Doljeşti, Tămăşeni,<br />
Sagna, Roman, Gâdinţi, Horia, Ion Creangă,<br />
Secuieni and Icuşeşti). Surprising is the fact that in<br />
the same interval there are situated Războieni,<br />
Boteşti, Văleni and Bahna communes, which,<br />
though they have a roughly hilly relief, thanks to<br />
the presence of some natural monuments and<br />
protected areas of local interest, succeed in<br />
reaching the inferior limit of the interval (7/8<br />
points). The minimum score, the interval between<br />
3 and 6 points, is gained by the communes situated<br />
in the Central area and the Western extremity of<br />
the county.<br />
The assessment of the anthropic potential<br />
By overlapping the elements specific to the<br />
anthropic potential (historic monuments of national<br />
interest, contemporary architecture, museums,<br />
public collections, folk art and traditions, shows<br />
and concerts institutions), it is obtained Figure 2<br />
which offers a relevant imagine regarding the<br />
anthropic potential on communes in Neamţ County<br />
(fig. 2). According to the assessment of the<br />
anthropic resources, the minimum score is<br />
assigned to Boghicea, Horia, Ion Creangă, Oniceni,<br />
Poienari, Săvineşti, Stăniţa and Valea Ursului<br />
communes (0 points), and the maximum number of<br />
points were gained, as it was expected, by Piatra-<br />
Neamţ municipality (25 points).<br />
Figure 2 The evaluation of Neamţ County<br />
anthropic potential<br />
A very high score for a rural area, is<br />
obtained by Vânători-Neamţ commune (22 points),<br />
and also by the communes categorized in the 15 –<br />
19 points interval, whose anthropic patrimony is<br />
recognized at national level (Alexandru cel Bun,<br />
193<br />
Lucrări Stiinţifice – vol. 55/2011, seria <strong>Agronomie</strong><br />
Agapia, Ceahlău, Roman, Târgu-Neamţ and<br />
Tazlău).<br />
The communes with a satisfying score, with<br />
a total amount of points between 10 – 14, are<br />
mainly situated in the Northern area (Borca,<br />
Fărcaşa, Poiana Teiului, Pipirig, Brusturi,<br />
Grumăzeşti, Bălţăteşti) and in the Central area of<br />
the county (Crăcăoani, Negreşti, Gârcina,<br />
Pângăraţi, Piatra Şoimului, Zăneşti, Mărgineni,<br />
Bârgăoani, Dragomireşti, Tupilaţi) and only<br />
isolated in the Western area (Taşca) or the<br />
Southern area (Români). All these communes are<br />
gifted with a developed anthropic potential.<br />
A merely lower score is detained by the<br />
communes in the 5-9 points interval, which can be<br />
identified in the Central, Western, South-Western<br />
and only isolated in the Eastern area. The lowest<br />
score was assigned with 0 to 4 points to the<br />
communes situated mainly in the Eastern area<br />
(Cordun, Icuşeşti) and isolated in the Central area<br />
(Ghindăoani, Dumbrava Roşie, Săvineşti, Dochia)<br />
and the North-Eastern area (Urecheni and<br />
Păstrăveni).<br />
The assessment of the tourist<br />
infrastructure<br />
When evaluating the specific tourist<br />
infrastructure of Neamţ County, there have been<br />
taken into account the scores obtained at the subchapters<br />
regarding the assessment of the<br />
accommodation units, the treatment and recreation<br />
structures, of the infrastructure necessary for<br />
organizing conferences, and also of the sky path<br />
and of the cable-transport installations. But<br />
analyzing Figure 3, it can be observed that the<br />
maximum score is gained by Piatra-Neamţ<br />
municipality (18 points), which has numerous<br />
tourist accommodation structures, endowed with<br />
the infrastructure necessary for organizing<br />
conferences, and also recreation installations,<br />
cable–transport and sky path. The minimum score<br />
was obtained by the communes located especially<br />
in the Eastern, North-Eastern and South-Eastern<br />
areas (fig. 3).<br />
A very high score is assigned to the<br />
communes neighboring Piatra-Neamţ municipality<br />
(Alexandru cel Bun – 13 points, Dumbrava Roşie –<br />
9 points, Piatra Şoimului – 7 points), Târgu-Neamţ<br />
municipality (14 points) and the bordering<br />
communes with a high tourist potential (Agapia –<br />
11 points, Răuceşti, Bălţăteşti – 14 points,<br />
Vânători-Neamţ – 7 points), Roman municipality<br />
(12 points), and also the West and South-East areas<br />
(Ceahlău – 16 points, Hangu – 13 points, Bicaz –<br />
14 points, Tarcău – 13 points). Though isolated,<br />
the same score is obtained by Tupilaţi commune (7<br />
points).
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Figure 3 The evaluation of the tourist infrastructure<br />
potential in Neamţ County<br />
By analyzing the same figure, one can<br />
observe that the average score (the interval 3-5<br />
points) is obtained, with little variation, by the<br />
communes located both in the mountain and sub-<br />
Carpathian areas of the county and the communes<br />
around Roman municipality (Horia, Secuieni,<br />
Cordun, Dulceşti, Gherăeşti), it being crossed by<br />
two important roads: E85 and DN15D.<br />
The rest of the communes, mainly situated<br />
in the Eastern, North-Eastern, Central-Eastern and<br />
South-Eastern areas, are defective from the point<br />
of view of the tourist infrastructure, reason why<br />
they are situated in the interval 0 – 3 points.<br />
The assessment of the technical<br />
infrastructure<br />
In the evaluation of the technical<br />
infrastructure, which includes the public transport,<br />
the town infrastructure (water and gas supply and<br />
sanitation) and the telecommunication<br />
infrastructure, the used information are the ones<br />
up-dated till 2007. Hence, the investments made<br />
between 2007-2010 have not been taken into<br />
consideration, especially the modernization of the<br />
communal roads, through the European funds<br />
SAPARD, respectively FEADR. Therewith in the<br />
communes Drăgăneşti, Ghindăoani, Negreşti,<br />
Văleni, Ruginoasa, Dochia, Boghicea, Gâdinţi and<br />
Pânceşti there is a lack of data basis.<br />
The technical infrastructure is assessed in 0<br />
– 24 points interval. By analyzing Figure 4, one<br />
can observe that the technical infrastructure is<br />
developed mainly in the municipalities/ towns of<br />
the county, as well as in the neighboring<br />
communes (fig. 4). Expectedly Roman<br />
municipality has the best score (24 points), the<br />
town being crossed by the most important road-<br />
E85, that traverses the entire North-East<br />
Development Area, and which is about 10 km far<br />
from the cross of two European Roads. Very high<br />
scores have obtained not only the commune<br />
Săbăoani (20 points), but also Piatra-Neamţ,<br />
Târgu-Neamţ, Bicaz, Pângăraţi, Săvineşti, Taşca<br />
194<br />
(19 points) and Alexandru cel Bun and Podoleni<br />
(17 points).<br />
Therewith, the communes crossed by<br />
important roads gained a satisfactory score (12-16<br />
points): Ceahlău, Bicazu Ardelean, Dumbrava<br />
Roşie, Roznov, Zăneşti, Podoleni, Răuceşti,<br />
Timişeşti, Tupilaţi, Boteşti, Gherăeşti, Cordun,<br />
Dulceşti, Făurei, Trifeşti, Horia and Secuieni. The<br />
exception is the commune Oniceni, which,<br />
although is not crossed by any important road,<br />
comes under the same interval of points.<br />
The communes located in the North, North-<br />
East, North-West and in the centre of the county,<br />
are characterized by lower scores, between 6 and<br />
11 points, and less the ones in the South, South-<br />
East and East.<br />
The lowest score (0 – 5 points) has been<br />
gained by the communes with poor roads,<br />
urbanistic and communication net, located mostly<br />
in the center (Crăcăoani, Grumăzeşti, Ţibucani,<br />
Războieni, Dragomireşti, Ştefan cel Mare, Piatra<br />
Şoimului, Borleşti) and eastern area (Tămăşeni,<br />
Doljeşti, Bîra, Stăniţa, Ion Creangă, Icuşeşti, Valea<br />
Ursului), and isolated in the South (Rediu,<br />
Cândeşti), North - West (Fărcaşa) and South- West<br />
(Dămuc).<br />
Figure 4 The evaluation of the technical<br />
infrastructure of Neamţ County<br />
General tourist assessment<br />
In order to create the Figure 5, that<br />
corresponds to the general tourist assessment of the<br />
Neamţ County, there were summarized all the<br />
information, which were the basis of the evaluation<br />
of the tourist resources (anthropic and natural<br />
potential) and of the infrastructure (tourist and<br />
technical). Finally, it has been drawn up the tourist<br />
map of the county, marking the limits of the<br />
communes, and which include all the components<br />
of a general tourist evaluation (fig. 5).<br />
The final score is between 5 and 72 points,<br />
the highest score being assigned to Piatra-Neamţ<br />
municipality, and the lowest to Boghicea<br />
commune. The score gained by Piatra-Neamţ<br />
municipality is fully legitimate, because it is
situated at the top of the hierarchy, not only<br />
regarding the tourist resource (37 points – second<br />
position), but also regarding the tourist<br />
infrastructure (37 points – first position).<br />
The second place in the tourist evaluation is<br />
offered to Ceahlău commune with 62 points, being<br />
situated on the third place from the perspective of<br />
the tourist resources (33 points), respectively the<br />
fourth place at the level of tourist infrastructure (29<br />
points). The best score gained by Ceahlău<br />
commune is thanks to Durău Resort with an<br />
accommodation infrastructure which worth being<br />
envied, and also to the special natural potential of<br />
Ceahlău National Park.<br />
The third place, in the interval from 47 to 60<br />
points, is obtained by Roman municipality with a<br />
total amount of 59 points. Though the town is not<br />
very well situated from the point of view of the<br />
tourist resources (23 points), at the level of the<br />
tourist infrastructure it occupies the second place<br />
with 36 points. This is mainly due to the technical<br />
infrastructure in the area, the town being crossed<br />
by the most important road of the North-East<br />
Development Region which is E85, Roman being<br />
located at approximately 10 km from the cross of<br />
two European roads (E85 and E58).<br />
In the same interval it is also situated<br />
Alexandru cel Bun commune which occupies the<br />
fourth place in the general hierarchy, with a total<br />
amount of 56 points, from which 26 points are<br />
gained thanks to the level of tourist resources and<br />
30 points from the infrastructure level.<br />
Figure 5 The general tourist evaluation of Neamţ County<br />
195<br />
Lucrări Stiinţifice – vol. 55/2011, seria <strong>Agronomie</strong><br />
The next two positions, Vânători-Neamţ<br />
(fifth place) and Târgu-Neamţ (sixth place) have<br />
both gained the same score of 47 points. This is<br />
due to both the special natural potential of<br />
Vânători-Neamţ Natural Park, and the anthropic<br />
potential in the area (the group of monasteries and<br />
hermitages) which positively influence the tourist<br />
infrastructure (especially the accommodation one).<br />
In the interval 33 – 46 points there are<br />
situated the communes/localities with high tourist<br />
potential, but not entirely used at its real value.<br />
They are situated mainly in the mountain area<br />
(Taşca – 44 points, Pângăraţi – 43 points, Agapia –<br />
42 points, Tupilaţi – 40 points, Bicaz – 38 points,<br />
Gârcina – 37 points, Bicazu Ardelean – 36 points,<br />
Bălţăteşti – 36 points, Pipirig – 36 points, Răuceşti<br />
– 34 points, Bicaz – Chei – 33 points, Borca – 33<br />
points). The exception is represented by Tupilaţi<br />
commune (40 points) and Săbăoani commune (33<br />
points), which are crossed by the European road<br />
E85, and also Zăneşti commune (33 points),<br />
crossed by DN15.<br />
A merely lower general score, situated<br />
between 19 – 32 points, is obtained either by the<br />
communes that have a poor tourist infrastructure<br />
(it is the case of the mountain localities – Fărcaşa,<br />
Poiana Teiului, Grinţieş, Hangu, Crăcăoani,<br />
Dămuc), or by communes that own limited tourist<br />
resources (it is the case of the localities situated on<br />
hill and field areas, in the Central and Central-East<br />
zone of the county).
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
The lowest score, between 5 and 19 points,<br />
is assigned to the communes with deficit both at<br />
the tourist resources level and the tourist<br />
infrastructure level. These localities are located<br />
mainly in East (Doljeşti, Boghicea, Stăniţa,<br />
Pânceşti, Gâdinţi, Poienari, Bozieni, Ion Creangă,<br />
Icuşeşti, Valea Ursului, Oniceni, Văleni,<br />
Ruginoasa), North-East (Drăgăneşti, Urecheni,<br />
Păstrăveni, Ţibucani) and only isolated in the<br />
centre (Negreşti, Ghindăoani) and South (Rediu,<br />
Cândeşti).<br />
CONCLUSIONS<br />
According to the presented analysis<br />
regarding the general tourist evaluation of its<br />
territory, Neamţ County can be divided in several<br />
zones and sub-zones. The well-known tourist<br />
zones, mature from the perspective of tourist<br />
infrastructure are: Ceahlău – Bicaz, Târgu–Neamţ,<br />
Cheile Bicazului – Hăşmaş and Piatra–Neamţ, and<br />
the sub-zones, mainly created after 2000 and which<br />
are now being developed are: Izvorul Muntelui<br />
Lake, Valea Tarcăului, Valea Muntelui and<br />
Roman. The tourist zones are generally situated<br />
around the national parks Ceahlău and Cheile<br />
Bicazului – Hăşmaş and Vânători-Neamţ Natural<br />
Park, but also in Piatra-Neamţ municipality, them<br />
being appreciated both at national and international<br />
level. In most of the cases, the sub-zones are<br />
complementary to the above mentioned zones,<br />
being mainly appreciated at the local level, but also<br />
at regional level, attracting numerous tourists from<br />
the main towns in the North-East Development<br />
Region (Iaşi and Bacău).<br />
196<br />
This new tourist zoning may represent a<br />
useful element in setting up new mid-term tourist<br />
development strategies for the area.<br />

PERSPECTIVES FOR MODERN AGRICULTURE DEVELOPMENT<br />
IN ROMANIA<br />
Lucian Ciprian MELUŢ 1 , Vasile MATEI 2<br />
e-mail: lucian.melut@gmail.com<br />
To understand the importance of this work, we must understand the importance of agriculture, in the Romanian space,<br />
in particular. Agriculture, as a primary field of activity including plant cultivation and animal husbandry, is a major<br />
sector of the national and global economy. Therefore, agriculture has to obey any rules, objectives and institutions that<br />
govern the economic system as a whole, whereas it is itself a distinct system that is interconnected with other<br />
subsystems within the economy. Modern agriculture begins in a research station, where scientists have access to the<br />
necessary supplies, expertise, and corresponding time. But, when the package is awarded to farmers, even the best<br />
farms cannot compare with the results we get as researchers. The basic challenge for modern agriculture is to sustain a<br />
better use of internal resources available in Romania. Presently, information in agriculture at the decision-making level<br />
comes from suppliers, researchers and private entrepreneurs rather than from local sources. However, the use of local<br />
information can minimize the use of external inputs, lead to more effective regenerating, or combine both.<br />
Modernization of agriculture presumes to be sustainable, economically viable, and socially responsible, protect<br />
resources, and serve as a basis for future generations. For this work, we have consulted some of the most important<br />
research literature, periodicals, scientific papers, technical and economic documentation, and other sources.<br />
Key words: perspective, agriculture, modern, sustainable, Romania<br />
At this stage, our world is characterized by<br />
fierce competition for economic supremacy, of<br />
excesses in the exploitation of nature followed by<br />
unpredictable disturbances for existence and health<br />
bodies, including humans, in such a complex<br />
socio-economic system, it becomes imperative to<br />
change the conception of the use of natural<br />
resources in general and, in agriculture in<br />
particular.<br />
In the context of Romania’s economic<br />
integration into the EU economic system, reforms<br />
are necessary for the Common Agricultural Policy<br />
(CAP), in order to ensure food security for<br />
humans and animals, and to develop new<br />
perspectives and possibilities for reform<br />
application.<br />
This should allow the use of resources, in<br />
favorable economic conditions, to comply with the<br />
principles of environmental protection and the final<br />
consumer (man), and with the principles that<br />
define quality of life in general.<br />
This work proposes the study of aspects on<br />
policy of integration of Romanian agriculture in<br />
the West, and attempts to develop viable solutions<br />
capable of ensuring the functionality and efficiency<br />
of their practice.<br />

MATERIALS AND METHODS<br />
The basis from which we began this research<br />
included the principles and analysis of production in<br />
agricultureand the policies on land market.<br />
Analyzing field reality, we concluded that the<br />
methods of structure, the forms of organization in<br />
agriculture and the axes of their financing, underpin a<br />
new vision in agricultural development.<br />
Thus, to achieve the objectives of this paper,<br />
theworking method used was as follows: data<br />
collection, analysis, processing and interpretation.<br />
RESULTS AND DISCUSSION<br />
Modern agriculture begins with the new<br />
vision of development policy administration<br />
(figure 1). Development efforts should focus on<br />
improving the institutional environment, through<br />
education and creation of market infrastructure,<br />
using new production technologies, and the<br />
creation of financial instruments. Influential<br />
international institutions, including the World<br />
Bank, Food and Agriculture Organization,<br />
Consultative Group on International Agricultural,
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
suggest that the best way to ensure public food is to continue modernization of agriculture.<br />

Figure 1. Prospects for agricultural development priority at the political level in Romania<br />
The concept of modern agriculture should<br />
not be regarded as a source of industrialized<br />
degraded, but supplemented by support,<br />
alternation, regenerative nature, constant and low<br />
external power. The modernization would like<br />
agriculture to become a competitive economic<br />
sector, even in Europe. Agriculture will be<br />
involved in the production of high quality food<br />
products, the conservation of natural landscape,<br />
and the development of tourism as an additional<br />
source of income.<br />
Development of sectors agriculture,<br />
livestock, fisheries, forestry and food, and<br />
overcoming structural problems will lead, in the<br />
medium and long term, to increase competitivenes<br />
and quality of life. Modernization is envisaged to<br />
reduce the number of people practicing<br />
subsistence agriculture, by creating a legislative<br />
framework providing for the establishment of<br />
specialized institutions, at government, to manage<br />
funds for agriculture. Thus, components can be<br />
simplified and can avoid errors.<br />
Another modern development solution,<br />
represents smallholder association and structural<br />
reform, by transforming subsistence farms into<br />
commercial farms; the principles should be<br />
oriented with the market economy, proftabile<br />
viable farms and the economy, and consistent<br />
with environmental protection.<br />
Agricultural Cooperative, similar to<br />
Western Europe, may be a modern development<br />
perspective. In Romania, so far, no co-created<br />
structures exist similar to those of old EU member<br />
states. Obviously there are no representation<br />

political class, to be reflected in appropriate<br />
legislation, to stimulate the creation and<br />
development of cooperative, could mean for 65%<br />
of Romanian agriculture, not only reduces the<br />
opportunities to benefit from European funds, but<br />
also creates further deterioration of the situation<br />
from the application of regulation Common<br />
Agricultural Policy (CAP) since 2013.<br />
Agricultural cooperative can develop only<br />
if the economic, legal and social environment, is<br />
one that would facilitate the emergence and<br />
development to sustain a direction to help develop<br />
agriculture. The logical order of things<br />
recommended is first the creation of this<br />
environment, where the agricultural cooperative<br />
could bring benefits to rural area entities the<br />
cumulative economic component of the society.<br />
In our opinion, such a cooperative<br />
environment where the concept of agricultural<br />
development would likelyexist, can form only if<br />
clear rules are promoted on the organization,<br />
operation and control for important segments of<br />
the agrarian economy. Measures of organization<br />
and systematization of agricultural land,<br />
specialization and the development of agriculture<br />
credit structures, conditions for credit guarantee,<br />
and of insurance against natural risk factors, and<br />
training on the product channels for the<br />
functioning of food, could define a normal<br />
economic environment for the development of<br />
agricultural cooperatives.<br />
In 2007, 29.4% of all holdings in the EU27<br />
were in Romania; this highlights the high degree
of fragmentation of agricultural holdings and<br />
stresses the need to establish agricultural<br />
cooperative.<br />

Another workable solution for modernizing<br />
agriculture is the agricultural research. Currently<br />
information on the performance of agricultural<br />
products comes from private investors, suppliers,<br />
from private researchers and other foreign<br />
sources, but not from Romanian institutions<br />
financed from state budget and local authorities.<br />
Insitutelor research funding in agriculture,<br />
livestock, pisciol, forestry and food, and funding<br />
research in universities and specialized<br />
agricultural is a solution of perspective that should<br />
start the modernization of agriculture.<br />
The educational role of agriculture<br />
fordeveloping, involves funding research in this<br />
area; the opposite we have the results, which we<br />
have to take into consideration. Also, there is a<br />
need to refocus research topics; they must provide<br />
high value biological products, raw materials,<br />
technologies, appropriate knowledge that<br />
contribute to agricultural modernization.<br />
There are EU rules on subsidiesfor lands<br />
that are made or maintained in good agricultural<br />
and environmental conditions.We propose to<br />
stimulate their cultivation into the national<br />
agricultural policy, which must exist.The vision of<br />
funds should be more restrictiveand turns to active<br />
farmers.<br />
Cap subsidies to farmers are not yet<br />
completed. Supporting manufacturers and<br />
maintenance of the population in rural areasis the<br />
opposite of a company pay capital which<br />
investing in agriculture.Therefore, we believe that<br />
a middle way to set some limits could be<br />
explored. It means that financial support should
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
be found to distribute as fair and<br />
transparentwithout forgetting that there are large<br />
firms that contribute to food production. For this<br />
there may be other instruments, not direct subsidy<br />
of hundreds of thousands of euro.For example:<br />
subsidized loans, investments, promotion of<br />
products on the market, etc.<br />
A modern vision for agricultural<br />
development, applicable in crisis, is the private<br />
storage.Means of action when a food crisis in<br />
Romania are limited. The only solution remains<br />
private storage support. The same measure can be<br />
achieved by creating toolsto intervene in support<br />
of farmers.<br />
Agricultural storage may prevent prices<br />
falling below the intervention price market,<br />
ensuring a guaranteed minimum price to<br />
producers.In principle, storage of agricultural<br />
products may be subject to exceptional measures:<br />
public storage, withdrawal from the market, the<br />
resale on the community market or sale outside<br />
the EU. In addition to these four destinations<br />
surplus agricultural productsmay beexceptional<br />
measures : sale on the community market at<br />
reduced prices or even selling products free<br />
(especially in the context of humanitarian or<br />
educational), and external termination, under food<br />
aid programs or intergovernmental agreements.<br />
Prolonged use of natural resourcesleads to<br />
depletion of ground water (groundwater). The<br />
greenhouse effect has become more<br />
pronouncedand it leaves its mark on the low level<br />
of water in dry periods when the need for water in<br />
agriculture is the largest.In our opinion, we must<br />
create a system to manage the water cycle. (Ex:<br />
regeneration of urban water, construction of<br />
artificial lakes that are fed by natural rainfall,<br />
especially in mountainous regions where rainfall<br />
is higher, etc.)<br />
All weather conditions require eliminating<br />
the risk of hail. Modernization of agriculture<br />
proposes the creation of platforms with hail<br />
rockets, especially in the basins of vegetables,<br />
fruit and wine, major cereal and exclusive areas.<br />
One cannot talk about modernism without<br />
preserving traditional values. We refer here to<br />
traditional agricultural products that are regionally<br />
specific(Example: cheese in fir bark, rozinci wine,<br />
spirit tree, honey, etc.).These products should be<br />
encouraged and supportedthrough sales<br />
partnerships on markets, for local communities<br />
nationally and internationally, and should be<br />
chosen as commercial targets.<br />
Forests have a significant role in<br />
agricultural business. In this respect we propose to<br />
provide support for afforestation, improving and<br />
expanding the economic value, diversifying<br />
200<br />
production and by opening new market<br />
opportunities, such as renewable energy, while<br />
maintaining a sustainable management, and<br />
respect for the multifunctional role of forests.<br />
GMO's enjoy a contradictory development,<br />
from the spectacular offensive years “80-“90 to<br />
the more or less categorical rejection of recent<br />
years. In our country, activities involving<br />
genetically modified organisms, obtained through<br />
modern biotechnology, are subject to special<br />
treatment of regulation, authorization and<br />
administration according to Law No. 3 of 2008.<br />
These activities include: the contained use of<br />
genetically modified organisms, introduction into<br />
the environment and the market of genetically<br />
modified organisms, import organisms /<br />
genetically modified organisms.<br />
These activities should take place only in<br />
conditions of environmental protection,and human<br />
and animal health,because biotechnology will be<br />
the future global agricultural production factor of<br />
progress, and everything that is produced in<br />
agriculture.<br />
CONCLUSIONS<br />
Modern agriculture does not require using<br />
the latest technologies in the field and the most<br />
expensive inputs.A modern agriculture is<br />
sustainable agriculture, which governs over all<br />
economic systems. A modern agriculture is one<br />
that understands the importance of plants and<br />
animals for human life.<br />
The concept of modern agriculture involves<br />
changing the mentality of those who practice<br />
agriculture, and the legal system. Efforts to<br />
develop agriculture, livestock, fisheries, forestry<br />
and food, should focus on institutional reform.<br />
This includes education and creation of market<br />
infrastructure, the use of new techniques and<br />
production technologies, and the creation of<br />
financial instruments.<br />
The association of small owners and<br />
structural reformis a prerequisite for agricultural<br />
modernization by transforming subsistence farms<br />
in commercial farms. It must be oriented to a<br />
market economy and to the establishment of<br />
national agricultural cooperatives, and the<br />
development for each region separately.<br />
The educational role of agriculture<br />
fordevelopmentinvolves funding research in this<br />
area; the opposite we have the results, which we<br />
have to take into consideration. Also there is a<br />
need to refocus research topics; they must provide<br />
high value biological products, raw materials,<br />
technologies, appropriate knowledge that<br />
contribute to agricultural modernization.
Supporting producers should be as fair and<br />
transparent as possible, without forgetting that<br />
there are large firms which are contributing to<br />
national food production.<br />
Private storage is a necessitybecause the<br />
remedies of Romania in a food crisis are limited.<br />
It also may prevent the market price declinebelow<br />
the intervention price, ensuring a guaranteed<br />
minimum price to producers.<br />
Platforms for hail and water use<br />
management in agriculture are essential for<br />
modern agriculture.Taking into consideration the<br />
climate change, they should be focused on these<br />
issues to avoid crises.<br />
Maintaining traditional values<br />
(agricultural products) are the opposite of<br />
genetically modified organisms.In our opinion, we<br />
believe that traditional values provide an<br />
agricultural market image. By creating<br />
partnerships for sales of agricultural products<br />
nationally and internationally, it adds value and<br />
confidence to Romanian agriculture.<br />
We encourage the biotechnology sector,<br />
because we believe that this will be the future of<br />
world agricultural production, and increasing<br />
productivity in agriculture means,but we<br />
emphasize that they must take placeonly in terms<br />
of environmental protection, human and animal<br />
health.<br />

The choice of this topic was induced by the many uses of rapeseed and especially by the current worldwide<br />
preoccupations to use alternative biofuels, in contrast with conventional fuels, that nowadays are the main source of<br />
pollution. This paper presents the production results of winter rapeseed (WOSR) hybrids, belonging to the Pioneer<br />
Hi-Bred International Company (semi-tall hybrids vs. conventional hybrids), exposed to the Eastern Europe’s<br />
continental climate conditions. There were selected 14 autumn rapeseed hybrids for evaluation from different locations<br />
in Romania, Hungary, Slovakia and Slovenia, during the years 2010 and 2011. During the analysis of the production<br />
capacity and oil content, there were seen differences between these two agronomic attributes, especially in terms of<br />
climate conditions. This paper also presents many advantages of growing MAXIMUS® rapeseed hybrids, with low<br />
levels of glucosinolate and erucic acid, from sowing to harvesting .These benefits that can be sustained by experienced<br />
farmers. The results of the conducted studies prove a great ecological plasticity and good resistance to harsh conditions<br />
experienced in the area of cultivation.<br />
Key words: performance, WOSR, Maximus, European condition<br />
Rapeseed (Brassica napus) occupies now a<br />
very important place in the world economy as a<br />
source of oil. The seeds of the new commercial<br />
hybrids have a content of oil from 48% to 51%, oil<br />
used both in alimentation and in industry.<br />
The progress made worldwide in improving<br />
the plant and in its multiple utilization fully<br />
motivates the reconsideration of rapeseed<br />
cultivation. The results of the plant improving<br />
program, based on the OGU-INRA CMS<br />
(cytoplasmic male sterility) hybridization system,<br />
and the role of DELLA proteins regarding the<br />
activity of the gibberellinic hormone (GA) allowed<br />
Pioneer Hi-Bred International INC. Company to<br />
obtain semi-tall hybrids, commercially named<br />
MAXIMUS®.<br />
The unique developing and the agronomic<br />
attributes of Maximus® hybrids, in comparison<br />
with the conventional hybrids is shown by the 5-<br />
8% additional seeds per unit area, lower vegetation<br />
treatments costs and the eased harvesting, reducing<br />
the fuel consumption and increasing the efficiency.<br />
The hybrid develops a strong root system and a<br />
fast growth even since the first stages of<br />

vegetation, entering in the winter season in the<br />
stage of 6-8 leaves, forming a well developed crop.<br />
It is easier to apply the phytosanitary treatment<br />
because of the plant’s height and the frequency<br />
decreases due to better resistance to pathogens<br />
(Sclerotinia sclerotiorum, Phoma lingam,<br />
Verticillium sp. and Plasmodiophora brassicae).<br />
Recent progresses on the improvement of<br />
production capacity and low content of<br />
glucosinolates and higher oil content have the<br />
effect of culture expansion and diversification of<br />
uses. With the discovery of genes conferring low<br />
heights to varieties of wheat and rice, marketing of<br />
semi-tall rapeseed hybrids is a part of the so-called<br />
Green Revolution.<br />
MATERIAL AND METHOD<br />
From the polifactorial experience with autumn<br />
rapeseed hybrids conducted in 2010 and in 2011 in<br />
the metropolitan network of Pioneer Hi-Bred<br />
International Inc., there were selected for analysis a<br />
number of 14 type 00 hybrids, with low glucosinolate<br />
and erucic acid content(4 Maximus® hybrids and 10<br />
conventional hybrids).
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Maximus® hybrids are 44D03, 44D04, 44D05,<br />
44D06 and the conventional hybrids are 44W22,<br />
44W29, 46W09, 46W10, 46W14, 46W20, 46W21,<br />
46W24, 46W30 and 46W31.<br />
The experiment was conducted in 61 locations<br />
in 2010 and in 2011 in 76 locations in Eastern<br />
Europe, specifically in Romania, Hungary, Slovakia<br />
and Slovenia (covering an area of 400,730 km2 and<br />
serving 39,540,000 citizens). Note that experience is<br />
part of a test program at European level called<br />
PACTS (Pioneer Crop Accurate Testing System).<br />
The calculation and interpretation of the data<br />
was made by the model proposed by Ceapoiu N.<br />
(1986), using variance factors: hybrids,<br />
experimentation regions and years. The production<br />
and the oil content are influenced by the technology<br />
that the company uses, and the results are<br />
represented by an overall analysis under the<br />
influence of hybrid x year x region of experimentation.<br />
RESULTS AND DISCUSSIONS<br />
The subject of this research is the winter<br />
rapeseed hybrid production potential in the<br />
Eastern Europe’s climate and terrain conditions,<br />
during the years 2010 and 2011.<br />
In the area experimented for two years there<br />
were grown both semi tall Maximus® and<br />
conventional hybrids. Overall, habitat conditions<br />
were similar, differing only from year to year, with<br />
a low germination the autumn of 2009 followed by<br />
a cold winter, with plenty of snow that maintained<br />
the crop’s heath, without registering dangerous<br />
frosts.<br />
204<br />
The precipitations in the spring and summer<br />
of 2010 have been very high, almost double<br />
compared to a regular year. Registered losses were<br />
mainly because of the frequent rains accompanied<br />
by hail. The harvest recorded was low, the Eastern<br />
European average being 2.6 tons/acre.<br />
The rape culture sown in the autumn of 2010<br />
found more favorable conditions compared with<br />
the autumn of 2009. Significant areas were sown<br />
with rapeseed due to the favorable price and the<br />
increasing demand for biofuels. The winter of 2010<br />
was mild, therefore no major losses were registered<br />
because of frosting and the crop’s condition was<br />
good.<br />
The spring rains and the high temperatures<br />
registered during summer time favored plant<br />
growing and development. During flowering and<br />
grain filling have been recorded favorable<br />
conditions for rapeseed. The average annual<br />
production in 2011 in Eastern Europe was higher<br />
than in 2010, registering a value of 3.0 to/acres.<br />
(figure 1)<br />
The concerns regarding the performance of<br />
the analyzed hybrids are a major goal, so that by<br />
applying the newest knowledge, the contribution of<br />
rapeseed for oil increases annually. Therefore, we<br />
calculated the average of the two categories of<br />

Average production of autumn rapeseed<br />
hybrids and the meaning of the differences are<br />
presented in tablet 3. Is observed a significant<br />
difference in the production capacity of the<br />
Maximus ® hybrids reported to the two categories<br />
of analyzed hybrids, also, a significant negative<br />
difference for conventional hybrids reported to<br />
controls. Production differences are 8% for<br />
Maximus® hybrids, difference that prove a better<br />
adaptation to the weather conditions in Eastern<br />
Europe.<br />
Based on F test, we can make the following<br />
interpretations:<br />
Table 1<br />
Table 2<br />
1. The oscillations of hybrid production recorded<br />
significant differences. There is also a significant<br />
influence in the regions of experimentation. The<br />
mark of ecological conditions is very significant<br />
and there have been registered differences that<br />
can’t be provided.<br />
2. The interaction Hybrids x Experimental regions<br />
and Hybrids x Years are insignificant.<br />
3. The interaction Experimental regions x Years is<br />
also insignificant, meaning that the hybrids have a<br />
high level of ecological plasticity, unaffecting the<br />
production capacity from a region to another, in<br />
the same experimental year.<br />

Table 3<br />
Turning attention again to the climatic<br />
conditions of the two years, in general, we can say<br />
that 2011 was a more favorable year than the 2010<br />
for the autumn rapeseed culture. As seen on figure
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
2, oil content values are relatively close, the<br />
differences being insignificant. Oil content is<br />
influenced by climatic conditions, as evidence is<br />
the greater percentage of oil that has been<br />
206<br />
registered in 2011, when it was a better year for<br />
the rapeseed culture. The oil content of<br />
Maximus® hybrids is slightly over the average<br />
percentage of tall hybrids, both in 2010 and 2011.<br />
Figure 2 Graphical representation of the oil content of Maximus® hybrids and<br />
conventional hybrids in 2010 and 2011 in Eastern Europe (%)<br />
Due to the large number of locations where<br />
this experience was conducted and due to the<br />
farmers, it was not possible to keep financial<br />
records and to perform economic analysis of the<br />
evaluated hybrids. However, farmers have seen a<br />
number of advantages of Maximus ® hybrids,<br />
from planting to harvesting. Recalling the<br />
International Conference on Harvesting and<br />
Processing (Louisville, Kentucky, USA) has been<br />
brought to the attention of farmers that only by<br />
taking semi tall hybrids are saving € 35 / acre<br />
compared with harvesting the same area, but<br />
cultivated with conventional hybrids.<br />
The root system of Maximus ® hybrids do<br />
best in the early stages of vegetation, and in<br />
spring you can see fewer losses, showing good<br />
resistance to winter. The rapidly increasing<br />
growth rate since the spring makes growing semi<br />
tall hybrids a better run for the autumn cereals.<br />
The resistance of these hybrids to the attack<br />
of pests and diseases has been proven by many<br />
farmers, growers of rapeseed, the application of<br />
phytosanitary treatment is easier because of lower<br />
plant waist, stronger branching of Maximus ®<br />
hybrids and therefore the number of pods per<br />
plant; the plant requires no growth regulators or<br />
desiccant, plant maturing is uniform therefore no<br />
losses were registered, the speed and low costs of<br />
harvesting , the reduction of vegetable waste<br />
cultivation, represent the advantages of semi tall<br />
Maximus ® hybrids compared with conventional<br />
tall hybrids.<br />
CONCLUSIONS<br />
The return of the rape seed on the European<br />
market thanks to its new uses, determined the<br />
resumption of work for improvement regarding<br />
the reintroduction of hybrids on the market. The<br />
research of the Pioneer Hi-Bred International<br />
Company allowed the launch of semi tall hybrids<br />
on the market.<br />
The behavior of these hybrids on the<br />
Eastern European market, compared to<br />
conventional hybrids, was the basis for<br />
assessment and analysis of production capacity<br />
and oil content, typical for these two types of<br />
hybrids.<br />
In the two years of analysis there has been<br />
observed both production differences and the<br />
ecological plasticity of the hybrids. Also, the<br />
numerous advantages of Maximus® semi tall<br />
hybrids are the basis of their performance. A<br />
significant difference is observed in the<br />
production capacity of the Maximus® hybrids<br />
reported at the average between the two hybrid<br />
types analyzed. There is also observed a negative<br />
difference for conventional hybrids related to<br />
controls. The difference of production is 8% for<br />
Maximus® hybrids, fact that proves a better
adaptation to the Eastern Europe climate<br />
condition.<br />
The oil content is influenced by climatic<br />
conditions and presents insignificant amounts<br />
between the two types of hybrids analyzed.<br />

METHOD AND METHODOLOGY<br />
Materials used in this research are: literature,<br />
theme specific magazines, national and international<br />
conference proceedings and other publications.<br />
Quantitative analysis is performed on selected<br />
data and processed directly in the interview. The<br />
need to conduct this study resulted primarily from<br />
direct observation that in any circumstance where the<br />
supplying products consumer quantities offering far<br />
outweigh a person's calorie needs, the rest are<br />
discarded, although for that food or natural resources<br />

RESULTS AND DISCUSSION<br />
Continued growth in demand for agricultural<br />
products in physical quantities and quality<br />
increasing total rising to take into account the<br />
dynamics of the global human population growth<br />
has led to the idea of environment necessary to<br />
stimulate food consumption per person per day,<br />
from which we can determine the physical<br />
quantity, of food daily food structures to enable a<br />
person to show performance in the profession and<br />
have a good health.<br />
Or study methods and Eating rational about<br />
maintaining a normal body weight within the<br />
performance advantages and innovation. Also<br />
identified a significant waste of food and<br />
agricultural production chain all methods to<br />
combat this waste.<br />
Of the results need to increase natural<br />
production of quality organic products food and<br />
agricultural research topics shift to green<br />
technologies and innovative performances.<br />
Daily consumption concept is a family structure<br />
and composition of medium for a month. The<br />
average consumption (consumption basket)<br />
includes food and nonfood, according to the figure<br />
1.<br />
Average consumption needs to be taken as<br />
low or normal and is quantified in physical or<br />
value.<br />
Based on the statistical value of consumer<br />
basket cost indices can be determined or life index<br />
evolution of prices and costs of products and<br />
services that are necessary for public consumption.<br />
Cart is established for an average family of 2804<br />
people (NIS) and established the composition and<br />
value of monthly consumption basket for a month<br />
to ensure a minimum level of living and is a key<br />
element in setting the minimum wage which in<br />
2012 is of 740 lei.<br />

Nutrition experts say that the human body<br />
has the ability to choose foods for their metabolic<br />
needs of the five senses - sight, hearing, smell,<br />
taste, tactile sensitivity are involved in food choice<br />
behavior from a person in choosing quality and<br />
quantity of food. The body needs nutrients<br />
continuously unlike food intake is usually<br />
intermittent. All information that the body he<br />
received from internal and external environment<br />
through the organs of perception are sent through<br />
the nerve centers in the brain where they are<br />
processed and answers (decisions) turn into<br />
requirements:
hunger is the unpleasant sensation which can not<br />
be eliminated. It occurs at certain times the body<br />
was used to have some food;<br />
appetite appears before hunger and anticipation<br />
of the need to eat foods that can be controlled by<br />
the preferred and previous experience;<br />
satiety is a euphoric and is blocking needs to<br />
overcome a food consumption over the body and<br />
its metabolic capacity;<br />
repulsion is loss of control by the brain needs<br />
food limited to normal human body and lead to the<br />
individual consumption of large quantities of food<br />
that can reach a mass 6 kg / person, to<br />
de1kg/person/ m which is considered normal, it<br />
leads to overweight, obesity, severe health<br />
problems;<br />
anorexia generally characterized by lack of<br />
appetite caused by an imperfect health, caused by<br />
digestive diseases, mental illness that lead to food<br />
rejection, hereditary, etc., leading to physical and<br />
intellectual performance loss of those persons, to<br />
underfeeding and chronic body weight as normal.<br />
The whole human body is affected by<br />
undernourishment;<br />
preference, is the property of the body to<br />
consume only one type of food chosen selectively<br />
based on subjective evaluation preference and<br />
previous experiences.<br />
Overall response R of the body needs food,<br />
information received from internal and external<br />
environment, can be expressed by the relation:<br />
n<br />
R = Σ Fi (1)<br />
i=1<br />
where:<br />
F - represent the response, and - the number<br />
of possible response;<br />
n = 7 in our case.<br />
Normal weight of a person according to his<br />
consumption of food items can be calculated using<br />
the formula:<br />
G<br />
I = (2)<br />
H 2<br />
where:<br />
G - weight in kg;<br />
H - height person m;<br />
I - index weight.<br />
Ideal weight index has different values for men<br />
(Ib) and women (If) as follows: for men Ib = 23<br />
and vary between 20.5 and 26, for women if = 21<br />
and vary between 19 and 23.<br />
Suppose that a real man weighs 74 kg and a<br />
height of 1.72. Body mass index will be:<br />
G 74<br />
I = = = 25,08 > 23, ideal (3)<br />
H 2 1,72 2<br />
211<br />
Lucrări Ştiinţifice – vol. 55, seria <strong>Agronomie</strong><br />
Ideal mass index (IBI) is defined as:<br />
IBI = 23 x H2 = 23 X 1.722 = 68.04 kg (4)<br />
The man has also: 74 to 68.04 = 5.96 kg.<br />
For a person to avoid the accumulation of body<br />
weight to lead to overweight, admitted beyond<br />
ideal, he must make a daily balance of calories<br />
gained from food (Ea) and those spent in activities<br />
that make within 24 hours (Ec) - (B). Overall<br />
energy balance (B) within 24 hours will be:<br />
Ea<br />
B = Kilocalories/24 hours (5)<br />
Ec<br />
Here we have three possible cases:<br />
1. B = 1, we have a balanced energy balance and<br />
body weight is constant;<br />
2. B > 1, the body has a reserve of calories that are<br />
deposited as fat in the body, increasing body<br />
weight. It may be countered by intensifying<br />
activity in the 24 hours, through exercise or other<br />
activities thermal energy;<br />
3. B < 1, the body lacks calories, decreases body<br />
weight person, health problems may arise, lack of<br />
professional performance. In this case consult a<br />
nutritionist. But food consumption varies by<br />
geographic region, from country to country. Rapid<br />
change known culinary preferences depending on<br />
their economic development area or country and<br />
the ability of everyone to have income.<br />
For example, italians prefer original<br />
preferably organic foods, pasta, piazza etc. French<br />
cuisine is positioned in the pleasure of eating, are<br />
demanding and the emphasis on taste who<br />
appreciate cheeses, spices, sauces, etc. using wines<br />
in preparation. In Germany food is a necessity for<br />
health and performance the profession. Americans<br />
and English have common habits, prefer more<br />
meat cooked with vegetables, pasta, corn flakes<br />
with milk and bread in limited quantities. Chinese<br />
believe food tastes a whole cosmos and their<br />
associated healing property, use many spices,<br />
prefer large amounts of natural fruit and tea are<br />
served in a specific ritual. Consumes only needs<br />
giving them a powerful and innovative work. In<br />
European Union countries, food is based on a<br />
strong traditional emphasis conservative.<br />

Changes are slow and are based on the<br />
appearance of a new type of consumer, claims a<br />
new style and quality of life.<br />
From a sample study of 248 people on three<br />
meals compliance specific to Romanian, that<br />
breakfast, lunch and dinner follows:<br />
- 33% - not respecting these three tables;<br />
- 29%-amended its schedule needs of three meals;<br />
- 18% - say that dinner is the main meal;<br />
- 11% - do not serve breakfast in the morning;<br />
- 9% - respecting these three tables.<br />
The tendency to abandon the traditional<br />
three meals daily rooted in particular times of day.<br />
Today, other rhythms daily arise after its own<br />
dynamic adaptation and after the lifestyle of<br />
individuals. A diet with an optimal intake of<br />
calories generated for individual health status and a<br />
good performance level.<br />
But research shows us that families,<br />
restaurants, supermarkets, the dinners, the whole<br />
network from raw materials - producer - consumer,<br />
are scattered up to 50% of healthy foods and<br />
supplies. Generally each EU citizen throws (waste)<br />
on average 179 kg of food a year. The food that<br />
could feed throws 79 million citizens living below<br />
the poverty line and 16 million people receiving<br />
food from charitable societies and 95 million<br />
people would be consuming if only Europe could<br />
stop wasting food. In the case of vulnerable<br />
persons, lack of food leads to stress.<br />
A European Commission study warns that if<br />
nations do not take action now to reduce food<br />
waste, it could increase by 40% by 2020, especially<br />
in countries based on excessive food consumption.<br />
In the European Union, 2011, the waste food<br />
products account for 89 million pounds / year,<br />
respectively 179 kg / inhabitant and without<br />
adequate measures, food waste in 2020 could rise<br />
to 128 million tons annually. Food waste is<br />
centered 42% in the households and 39% in the<br />
food. Parallel to fight food waste have acted and<br />
improving the overall quality of food products, in<br />
terms of producing organic food products<br />
providing consumers a new quality of life.<br />
A rational and organic food will enhance<br />
individual performance. The dynamics of<br />
population growth (9 billion in 2050) and<br />
reduction of agricultural land for different reasons,<br />
advertising to increase agricultural production and<br />
a drastic saving them.<br />
CONCLUSIONS<br />
Daily food consumption should be limited to<br />
minimum calorie / person necessary for carrying<br />
out professional performance and a state of perfect<br />
health. First consumer awareness measures to<br />
212<br />
avoid any chance of food waste that can be<br />
redirected to the vulnerable in terms of food.<br />
Excessive food consumption over energy<br />
needs of the body, to boost performance and<br />
reduce waste leads individuals related to<br />
intelligence (IQ) and creativity.<br />
Agriculture plays vital role in providing<br />
sufficient food quality and ever-growing<br />
population. Agricultural production to encourage<br />
green technology and environmental protection<br />
that gives consumers a new quality of life. It is<br />
necessary to focus research topics green<br />
technologies, performance contributing to faster<br />
growth in agricultural productivity to keep pace<br />
with continuing growth in global demand for<br />
consumer food products.<br />
Increasing food production, while reducing<br />
consumption to a rational recycling food waste,<br />
combined with other measures, will provide live<br />
food for a mega global human population. is a<br />
great challenge for the knowledge society.<br />

World population reached 31 October 2011 to 7 billion people, primarily to ensure their food needs. But not only in<br />
quantities sufficient food, three times a day but also high quality. These attributes can fulfill ecological food product,<br />
found in small quantities at a price hight. Technologies new, performance, innovation is expected to reduce their price<br />
and production cost. But, to distinguish them on the market, products food green packaging must bear a certificate<br />
specifies that protects environmental quality and product recognition. This mark began in Romania in the European<br />
Union and other countries with developed agriculture. The problem of cost and production volume organic food be<br />
made in accordance with the rapid development rhythm world population. It is a challenge.<br />
Keywords: green, renewable, eco label, sustainability, innovation, recovery.<br />
Food commodities are unprocessed or<br />
processed products that contain necessary nutrients<br />
the human body. Codex Alimentarius Commission<br />
defines organic agriculture: a holistic approach to<br />
marketing, production management system that<br />
promotes and maintains healthy development of<br />
agro-ecosystems, including biodiversity, biological<br />
cycles and soil biological activity. Emphasis is<br />
directed to use management practices in line with<br />
company use external inputs, taking into account<br />
regional conditions that systems must adapt. This<br />
is done by using, where conditions permit,<br />
agricultural methods, biological and mechanical, as<br />
opposed to using synthetic substances, to perform<br />
any specific function to use.The label is any<br />
written material, printed, lithographed, engraved or<br />
illustrated elements containing product<br />
identification and accompanying the product or its<br />
packaging is adhering to. Purpose of labeling is to<br />
convey the necessary information corresponding to<br />
consumer demands to know and avoid possible<br />
risks. ISO 1400 standards on environmental<br />
aspects of products and services relate mainly to<br />
environmental labeling and life cycle analysis of<br />
products in which ISO 14020-1998 remember<br />
basic principles for environmental marking, ISO<br />

METHOD AND METHODOLOGY<br />
For this research we used to study literature,<br />
law and practice nationally and world wide .. Analysis<br />
is performed on selected data and processed based<br />
on a questionnaire. Motivation to perform this<br />
research resulted from a finding that more and more<br />
food products are products obtained by using<br />
synthetic fertilizers that are harmful to consumer<br />
health. Food products that are on the market are<br />
really natural and without eco label can not be sure<br />
that the product is authentic ecological respectively.<br />
RESULTS AND DISCUSSION<br />
The increasing trend of customer<br />
satisfaction in the highest degree led to increased<br />
"consumerism movement" worldwide for the<br />
following reasons:<br />
- consumers become more informed, assisted,<br />
demanding and sometimes capricious;<br />
- consumers know their rights and not limited to<br />
quality / food services, are more attentive to the<br />
impact they have on the environment and their<br />
health;<br />
- critical assessment of attitudes / activities<br />
consumerism in Europe and the U.S. showed a<br />
strong tendency to change in consumer activity in<br />
the future.<br />
This trend is reflected in the marketing<br />
policy on environmental product that must meet<br />
multiple requirements: use, handling, storage,
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
quality, mining, environmental impact and are the<br />
highest standards in the field.<br />
In the European Union are three Scientific<br />
Committees dealing with: consumer safety, public<br />
health and environmental protection and ecological<br />
products. Effects of environmental attributes of<br />
products is carried throughout their lifetime.<br />
Parallel to the development of organic<br />
products and competition increases. But consumers<br />
looking for products where the packaging stated:<br />
naturally occurring, biodegradable organic product<br />
or products, etc.<br />
Marking of organic products has become a<br />
tool for diversification of supply and promoting<br />
ecological marking product. In follow two<br />
directions:<br />
1.creating a green packaging;<br />
2.environmental labeling.<br />
In modern marketing, eco-labeling is the<br />
main agricultural firms. Labeling aims ultimately<br />
reducing production and consumption non<br />
sustainable how to obtain a higher quality of life,<br />
health and safety, all contained in the Declaration<br />
of Rio, Brazil, on environmental protection. The<br />
concept of labeling imposed manufacturers to<br />
redesign products / services so that new products<br />
are "friendly" relationship with the environment.<br />
This message can be transmitted through or burn<br />
marks on the product label information on<br />
certification, component percentages, size, etc..<br />
Labeling program first began in Germany in 1977,<br />
expanded in Europe, Brazil, Canada, China, Israel,<br />
Japan, USA, Korea, as part of a global network of<br />
global eco labeling, created in 1994, in order to<br />
encourage eco labeling products, information<br />
exchange and harmonization of programs. In<br />
Romania, the procedure for granting environmental<br />
labeling is provided in HGnr.189/2002 and granted<br />
those items / groups of organic products that meet<br />
the following conditions:<br />
- have competitive advantage in the competitive<br />
market of organic products;<br />
- product demand is high enough to favor the<br />
company;<br />
-advantages favorable environment (environmental<br />
protection);<br />
- protect the health of consumers.<br />
To obtain the eco-label food products,<br />
companies, manufacturers, importers, traders,<br />
service providers must address environmental<br />
authority for approval.<br />
Eco labeling objectives are:<br />
- promote economic activities, ecological<br />
environment friendly;<br />
- allow related products greener all productive<br />
chain:<br />
214<br />
product distribution use<br />
consumption product recycling recycling<br />
paking<br />
- communicate to the consumer information exact<br />
product / service of ecologically;<br />
- promote ecological products throughout life,<br />
reduced environmental impact.<br />
Specialist studies undertaken in the<br />
European Union revealed the following aspects of<br />
eco-labeling:<br />
- word "packaging is recyclable" is not<br />
synonymous with recycling, but that the packaging<br />
is made from recycled paper. Interpretations and to<br />
avoid confusion, mention should be explained<br />
clearly on the label;<br />
- authorized environmental arguments for labeling<br />
should be stored in a database of manufacturer, to<br />
be controlled by specialized inspectors;<br />
- eco labeling be widely publicized to eliminate<br />
confusion in the minds of consumers traditional;<br />
- manufacturers should take measures to reduce the<br />
selling price of organic products;<br />
- ecological attributes marking products:<br />
individuality, guarantee originality, quality<br />
assurance, consumer health guarantee.<br />
From the study of companies dealing with<br />
production and processing of food products, the<br />
question: What do you mean eco labeling food<br />
organic product?, The responses of those<br />
interviewed are:<br />
NCE<br />
APE<br />
PCAS<br />
CPE<br />
DPE<br />
0% 10% 20% 30% 40% 50%<br />

- 42% said they eco labeling defines an ecological<br />
(DPE);<br />
-28% believe that the product characteristics<br />
ecological eco labeling (CPE);<br />
- 19% believe eco labeling a product, an element<br />
that ensures their health (PCAS);<br />
- 8% considered eco labeling as a package for an<br />
ecological (EPA);<br />
- 3% do not know anything about eco labeling<br />
organic products (NCE).<br />
Of questionnaire-based study shows that<br />
most consumers (70%) perceive eco labeling as an<br />
organic product with its essential attribute: quality<br />
health care. However people who had knowledge
about organic products, consumers were shown a<br />
keen interest in how their eco labeling<br />
identification. The respondents argued that<br />
pollution is a threat to the future and environmental<br />
labeling of products has become an important<br />
method to human health. Reducing the negative<br />
impact of human activity on the environment, need<br />
shared by 95% of citizens is seen as a key factor<br />
that will redefine the marketing risk management<br />
by undertaking tasks sustainable local, regional,<br />
national and global. We must be aware that The<br />
lack of food, water and the soil (to support 7<br />
billion people) could lead to outbreak of conflicts<br />
between nations. However organic products by<br />
attributes will provide the best product that gives<br />
about consumers looking for: a longer life. Billions<br />
of dollars are invested in the pharmaceutical<br />
industry to create products for longevity. But the<br />
EU and some national governments support and<br />
enforce measures to reduce pollution resulting<br />
from industrial activity and encourage consumers<br />
to take decision, to choose to purchase products<br />
"environmentally friendly - eco friendly products."<br />
The study conducted among managers dealing with<br />
the production of organic products to the question:<br />
How do you perceive the future trend of organic<br />
products? responded:<br />

And practice confirms that without financial<br />

organic products because of bureaucracy and high<br />
costs will be a slow and uncertain. But<br />
environmental pollution knows no boundaries and<br />
more and more consumers have expectations about<br />
the quality of life. On the other hand, managers of<br />
firms have realized that among their<br />
responsibilities multiply, we add one: the green.<br />
From this point of view environmental<br />

strategic and integrated, based primarily on<br />
environmental issues, the integration of ecological<br />
marketing concept of "Green Marketing", based on<br />
a new relationship with consumers. Briefly, the<br />
notion of ecology (Ec), can be defined as:<br />

Ec = 3C + 3R= Σ Ci + Σ R (1)<br />
i=1 r =1<br />
where:<br />
C1 = conservation = C2 consumption C3 = control;<br />
R1 = recovery, R2 = reconditioning, R3 = reuse.<br />
Some manufacturers stimulates recovery of<br />

In the 3C group calls for a fair use and the 3R lead<br />
to recovery strategies to reduce excessive<br />
consumption of natural resources. Eco-label does<br />
not say that these products have no impact<br />
environment, but a smaller impact than others in<br />

- ecological score thus obtained is multiplied by<br />
the coefficient of performance (P).<br />
Each product to obtain eco-labeling must<br />
obtain a number of points between minimum and<br />
maximum points for the product, according to the<br />
rules.<br />
CONCLUSION<br />
Eco labeling products is still in its early<br />
stages, with development trends worldwide,<br />
including Romania. Organic products food costs<br />
are about 3% expensive than similar products and<br />
issue costs of environmental initiatives food firms,<br />
a problem still unsolved. But there are few highincome<br />
customers who prefer organic products.<br />
Although organic foods offer customers the highest<br />
quality of life and even extend life expectancy,<br />
ecological agricultural areas are experiencing a<br />
slow expansion. Long term and globally, I believe<br />
that in Romania, where agricultural land is only<br />
1.07 hectares per capita, an organic farming can<br />
not provide the necessary food for the population.<br />
Globally the situation is more critical, there under<br />
2 ha / capita and the year 2050 may reach the limit<br />
of about 10 billion people that I can support Tera.<br />
Can not provide food for many people green.<br />
Environmental issues including the role of<br />
environmental labeling of food products must be<br />
very well known companies in the field managers.<br />
Have encouraged ecological behavior of every<br />
citizen to protect nature, to reuse some raw<br />
materials. All we need food, to investigate new<br />
methods secure it through performance and<br />
innovation.<br />

STUDY REGARDING THE PERSPECTIVES OF ARGES COUNTY<br />
AGRICULTURE THROUGH THE FARMERS’ VISION<br />

This work aims to present a study regarding the perspectives of Arges agriculture through the farmer’s vision.This<br />
paper will disseminate only part of the information obtained by questionnaire. People who were interviewed are<br />
representatives of agricultural holdings with legal form and individual exploitations without legal form. The<br />
questionnaire aimed to identify the opinion of farmers according to legal form on the following issues: What kind of<br />
agriculture is consider necessary to be practiced in the county and the means for upgrading technology. A percentage of<br />
66% considers that it is necessarily highly productive agriculture, of large farms that use fertilizers, herbicides, etc., and<br />
only 34% for the traditional organic farming. As a result, the survey revealed that the farmers who have farms with<br />
legal form considers that they can modernize their exploitation by mechanization (33%), using new varieties (28%) and<br />
using new crop technologies.The same opinions have the farmers from the individual agricultural sector, there were no<br />
significant differences between the farmers from the exploitation sector with legal form.<br />
Key words: agricultural producers, questionnaire, Arges<br />
Rural areas in Romania are a cardinal<br />
component of the evolution of the Romanian<br />
economy. Three rural resources need to give the<br />
true dimension of the restructuring of the<br />
agriculture and rural development in our country:<br />
the use of agricultural area (14.8 million ha), farm<br />
labor (3.5 million) and total area of the countryside<br />
(90% of the country) (Micu M.M., 2012).<br />
In this perspective, Romania has to adopt<br />
agricultural policies to include elements of<br />
accelerating the process of compatibility,<br />
especially in the regulation of the property rights<br />
and guaranteeing it, but also to improve<br />
infrastructure and education in this specific<br />
segment (Alecu I.N., 2002).<br />
In specifying of the agricultural policy must<br />
start from the fact that agriculture is not only an<br />
economic sector producing goods and profits, it is<br />
also a way of life and rural areas is not only a place<br />
of production, but at the same times a social and<br />
cultural space with complex issues concerning the<br />
overall state of the nation.<br />
Agriculture is an important component of<br />
Arges economy in rural areas constantly being<br />
introduced reform measures, including law<br />
enforcement in the field and of the current EU<br />
programs (Drăghici M. and co laboratories, 2010-<br />
1 University of Agriculture and Veterinary Medicine, Bucharest<br />
2 University of Agriculture and Veterinary Medicine, Iasi<br />
2011, Popescu M., Popescu, G., 2007 Tudor V.,<br />
2008).<br />
One of the main agricultural areas of the<br />
country, Arges County is well known for its cereal<br />
crops, industrial crops and fruit.<br />
More than half of the county's agricultural area is<br />
arable land. The rest is filled with orchards,<br />
nurseries, vineyards, pastures and meadows.<br />
Agricultural area, totaling 341,033 ha, is operated<br />
as follows:<br />
- 332,393 hectares in private farms<br />
(individual and associations);<br />
- 8.640 hectares in the state sector.<br />
Data currently available in the Arges County<br />
show that the situation is more delicate every year,<br />
the number of farmers, but also of animals is<br />
declining.<br />
Not surprising that the level reached by land<br />
worked is alarming, one of the causes of increasing<br />
costs in agriculture.<br />
Our data indicate that we are dealing with a<br />
decrease in average with 5% compared to 2002<br />
figures from the previous census was held. The<br />
number of farms fell by 5.15%. In 2010 were<br />
reviewed 162,858 agricultural holdings in Arges,<br />
of which 161,798 without legal form. Note that<br />
individual farmers are unrelated and yet still work<br />
the land to live sometimes from day to day.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Also, the use of agricultural area of the farms<br />
decreased by 5.5% over 2002, which means a high<br />
degree of division of property (in the meantime,<br />
some courts have split as a result of the<br />
inheritance). The data show that the number of<br />
animals in the county fell significantly by over<br />
10% in some cases (Manole S., 2011).<br />
In these conditions, this work makes a study<br />
on the prospects of Arges agriculture through the<br />
farmer’s opinion considering the theory, the<br />
problem and the constraints. Without a strategy is<br />
missing the consistency in using the funds,<br />
resources are wasted, especially time, that it flows<br />
against agricultural producers who live in rural<br />
areas.<br />
MATERIALS AND METHODS<br />
The usefulness of the questionnaires is given<br />
by different categories of provided information: the<br />
hierarchy of needs, preferences, attitudes, consumer<br />
habits and buying, consumer motivations and so on.<br />
Also regarding the utility, it refers to respondents who<br />
may be associated with specified categories of<br />
information. Thus, information on market phenomena<br />
or processes is circumscribed to the specific of the<br />
community’s reference. For example, people can<br />
gather information from the various segments formed<br />
by gender, age, education, occupation, geographical<br />
area, home environment, income, household<br />
structure and size. These data can be obtained more<br />
easily through the questionnaire (Colibaba D., 2001).<br />
The information collected through the<br />
questionnaires are both quantitative and qualitative,<br />
that can be detailed by certain criteria, thus to allow a<br />
deep knowledge of the market issues that cannot be<br />
addressed based on secondary sources. Arguments<br />
about the importance of questionnaire as a tool for<br />
gathering information about the market of goods<br />
consumer and services enable the formulation of the<br />
conclusion that development, testing and application<br />
of questionnaires requires complex and varied<br />
knowledge from the researchers.<br />
In practice, for various reasons, some<br />
communities may not be recorded with the total units<br />
that compose them, whether it would have required<br />
heavy expenditures or research results that efficiency<br />
is not ensured. All these reasons and others not<br />
specified, requires more frequent organization of<br />
statistical surveys such as partial records.<br />
Planning and execution stages of the<br />
questionnaire can be considered as following:<br />
1. Setting goals questionnaire, which is<br />
established for research purposes. Are specified<br />
operational information to be obtained and questions<br />
are formulated based on their questionnaire.<br />
2. Defining the population, in which is set the<br />
community studied, the unit of observation and the<br />
survey unit.<br />
3. Establish the data collection method, which<br />
sets the spatial coordinates, temporal and modal of<br />
the research.<br />
218<br />
4. Develop of a questionnaire is based on a<br />
previously set of objectives, questions contained in it<br />
that can be divided into several categories.<br />
Questionnaire must be clear, not vague, not to<br />
influence the response, does not use the same scale<br />
row (avoid the effect of inertia) (Savoiu G., 2011).<br />
The questionnaire was applied during<br />
September-November 2011 in Arges County in a<br />
number of 53 persons. The questionnaire applied was<br />
well structured, being divided into chapters, relevant,<br />
containing over 50 questions. This work will<br />
disseminate only part of the information obtained by<br />
questionnaire. People who were interviewed are<br />
representatives of agricultural holdings and legal form<br />
of individual farms without legal form.<br />
The questionnaire aimed to identify was the<br />
opinion of farmers according to legal form on the<br />
following:<br />
- What type of agriculture is necessary to be<br />
practiced in the County;<br />
- Ways of upgrading technology.<br />
It also took into account the following, obtained<br />
through the questionnaire:<br />
- Age of respondents;<br />
- Level of education of respondents;<br />
- Form of relief where farms are located;<br />
- Access development measures.<br />
Making the study is due also to the research,<br />
statistical data analysis and interpretation. This,<br />
together with extracts from the theoretical literature,<br />
enabled the assessment of certain issues raised<br />
throughout the work.<br />
RESULTS AND DISCUSSION<br />
In terms of age, we see that of all farmers<br />

For farmers with legal holdings segment as<br />
that prevails farmers aged 41-50 years is not<br />
recorded a difference of age than in young farmers<br />
appreciate that young people continue to consider<br />
an important branch of agriculture economics in<br />
Arges County (Micu M.M., 2011).<br />
We believe that the questionnaire was<br />
conducted on farmers of all ages in order to<br />
observe their opinion uniformly (figure 1).<br />

ROMANIAN ASSOCIATION AGRICULTURAL PRODUCERS PRIMACY,<br />
POWER EUROPEAN EXAMPLE<br />

This paper wants to emphasize the vitality of the association and cooperation in agriculture, food and related services in<br />
Romania for efficient operation and development of romanian agriculture. This phenomenon had and still has a huge<br />
impact for European farmers and especially romanian. The force of the countries with a strong agriculture in Europe<br />
and all over the glob is in the farmers association and cooperation. Romania has 1192 associations of livestock farmers,<br />
accounting for a total of 213,071 members. The EU agricultural producers are well represented in the European<br />
Parliament agriculture committee by COPA-COGECA, the organization which represents 56 national organizations<br />
from 25 countries out of 27 of the union. Our country must understand that without a reform aimed at streamlining the<br />
professional and union of a strong unified voice on national and European level, our agriculture will live from its former<br />
glory.<br />
Key words: (association, cooperation, romanian agriculture, organization)<br />
Farmers association in professional strong<br />
economic role and representation means a driving<br />
force for agricultural powers in Europe and the<br />
world. In countries with strong agricultural lobby<br />
and force professional organizations representing<br />
producers of agricultural, food and related services<br />
is clear that farmers have the power to decide<br />
strategy is in line with developments in the market<br />
sector. In Romania, unfortunately, is not the case<br />
and the well was recently highlighted during a<br />
symposium organized by the Institute of Social<br />
Economy. The only salvation for those working in<br />
agriculture, the state budget, but also to increase<br />
productivity in agricultural sector policies are not<br />
made on foot, but policies to strengthen<br />
agricultural associations and farmers' associations.<br />
I believe that agriculture is the only solution for<br />
Romania, for recovery and rural Romanian village.<br />
(Stefan N., 2012).<br />
Once born and active, professional and<br />
cooperative organizations may, for a smart state to<br />
become formidable partners for implementation of<br />
large agro-rural development projects for resource<br />
conservation and environmental protection. (Berca<br />
M şi colab, 2002). No country in Europe has not<br />
only developed a strong agricultural potential due.<br />
We first need consistency and stability<br />
(Cioloş D.,2011).<br />

MATERIALS AND METHODS<br />
To characterize the importance of linking and<br />
cooperation of agricultural producers, food and<br />
related services in Romania have been taken into<br />
account a number of indicators, such as association,<br />
cooperation, organization of farmers, agricultural<br />
sector development and efficiency.<br />
Statistical data were collected from the Ministry<br />
of Agriculture and Rural Development, COPA<br />
(Committee of Professional Agricultural Organisations<br />
of the European Union) and members of the National<br />
Association of Agricultural Producers Youth in<br />
Romania, processed and interpreted, and predictions<br />
as existing trend, especially in Europe and the world.<br />
RESULTS AND DISCUSSION<br />
Farmers are represented at European level<br />

Organisations of the European Union) organization<br />
comprising 56 national organizations as follows:<br />
England - 3, Austria - 1 Belgium - 2, Cyprus - 4,<br />

organization representative on the 21 common<br />
market sectors (COPA, 2012).

Unfortunately Romania is not to have a pan-<br />
European economic reasons and because of the<br />
vanity of representatives of professional<br />
organizations.<br />
Subsistence farms cover approximately 45%<br />
of agricultural land located in the culture with<br />
approximately 90% of the total number of<br />
holdings. This context is contrary to the general<br />
interests of farmers as to increase competitiveness<br />
must capitalize on the market agricultural products<br />
that meet quality and quantity.<br />
This can be successfully applied in a<br />
relatively short period only coooperarea farmers.<br />
Mr. Ilie Sirbu was highlighted when<br />
Minister of Agriculture that, ,,so that they can get<br />
more money from European funds and the state<br />
budget. Together have a greater force than<br />
working individually. I think it is necessary to have<br />
a group of farms managed by young farmers,<br />
especially that we have this European funds. These<br />
groups will form the core fact that average farm,<br />
with large farms are producing for the domestic<br />
market and even to foreign markets. "<br />
Farmers have little interest in professional<br />
organizations due to low information, low level of<br />
awareness, different perceptions of people<br />
involved in associative forms and CAP's old bad<br />
habits (Cooperative Agricultural Production),<br />

NUMARUL DE ORGANIZATII PROFESIONALE ALE CRESCATORILOR DE ANIMALE<br />
Figure 2 Number of members of Animal Breeders Associations in Romania by county (MADR, 2012)<br />
Members of these associations have in<br />
operation a total of 518,637 bee colonies, 623,598<br />
head cattle, buffaloes and buffaloes, 8359 horses<br />
heads, 4,388,339 sheep and goats, 16,907,634 birds<br />
heads, 170,814 heads swine and 21,014 heads<br />
mixed (M.A.D.R., 2012 ).<br />
In addition to the above associations are 95<br />
representative organizations (A.N.T.P.A.R., 2011)<br />
covering most sectors of the field being filled with<br />
individual farms and other agricultural producers<br />
to reach the existing production capacities.<br />
All types of agricultural associations<br />
established in Romania, professional or economic<br />
type, operating locally and not have power of<br />
dialogue with the authorities (Stefan N., 2012).<br />
Due to decentralization structures<br />
agriculture ministry and the lack of clear<br />
legislation are difficult agricultural chambers<br />
functioning of Romanian agriculture (Bercu F. and<br />
et al, 2012).<br />
If political parties would switch to a type of<br />
strategy to support these associations with<br />
European money would help restore the chain of<br />
product as opposed to indirect financing of<br />
multinationals, oil operators or from outside jobs,<br />
if we account that over 70% of agricultural<br />
products coming to Romania are imported (Stefan<br />
N., 2012).<br />
Romanian agriculture needed by 2014 is to<br />
have associations of producers and producer<br />
groups on economic criteria. Ca şi plan de acţiune<br />
ar trebui avut în vedere următoarele(A.N.T.P.A.R.,<br />
2011):<br />
Associations of producers enactment and<br />
empowering producer organizations with<br />
participation in decision measures<br />
(participation in measures of PNDR approval<br />
certificates of producers, obtaining funds<br />
through associations, etc.).<br />
Support for the state costs (500,000 euro / year<br />
reserve fund government) participation in<br />
Brussels on relevant organizations.<br />
Establishment of Agricultural Chambers of<br />
producers in their favor. Disbursement of 10<br />
million euro’s to set up agricultural chambers.<br />
Promotion program which is funded by the EU<br />
by 50%, the remaining funds for the Member<br />
State and inter-professional organizations, the<br />
latter must contribute at least 20%.<br />
Producer groups on economic criteria<br />
established in 2014, will receive the first five<br />
years of recognition based on a business plan,<br />
marketed production up to 1,000,000 euro’s,<br />
aid in annual installments of 4% (first year)<br />
and 10% (fifth year) of the amount approved.<br />
The main advantages of associative forms:<br />
- Facilitates communication between farmers, on<br />
the one hand and between their representatives<br />
and government institutions, on the other;<br />
- Helps reduce production costs;<br />
- Give possibility of competitive production<br />
technologies;<br />
- Planning and production changes according to<br />
demand quantitative and qualitative market;<br />
- Have a high capacity to negotiate the purchase of<br />
inputs such as capitalization and products.
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
- Facilitate access to European funds and bank<br />
borrowing;<br />
- Helps to better promote their products both<br />
domestically and foreign.<br />
Before we rest on the thought that others<br />
come to help us, we must help ourselves. We must<br />
not be indifferent about our future! To trust in<br />
ourselves and in God. Should we do anything at all<br />
we go any better (Lăpuşan A. 2011).<br />
CONCLUSIONS<br />
Professional organizations are the drivers of<br />
agricultural farmers of the great powers in Europe<br />
and even worldwide.<br />
The presence of one or more primary<br />
Romanian organization that is active-member-is<br />
the Committee of Professional Agricultural<br />
Organisations of the European Union (COPA) to<br />
be able to support us and promote the Romanian<br />
agricultural sector with its specific features.<br />
Many farms in Romania may be more<br />
efficient just by association and cooperation<br />
between farmers.<br />
Romanian farmers began to realize that the<br />
only chance of progress, become efficient and<br />
competitive market is to be united.<br />
Associative forms of Romania still remains<br />
at an early stage, the need to follow a process of<br />
reorganization, professionalism and efficiency.<br />
It is difficult but not impossible, it takes the will,<br />
ambition and perseverance to recover Romanian<br />
agriculture.<br />

PARTICULARITIES REGARDING THE EVOLUTION OF ROMANIAN<br />
BAKERY MARKET IN THE CONTEXT OF ECONOMIC CRISIS<br />
1 University of Agriculture and Veterinary Medicine, Iasi<br />
Ştefan VIZITEU 1<br />
e-mail: stefan.viziteu@yahoo.com<br />
The unstable economic environment has prompted businesses to adopt security measures or to reconfigure certain<br />
courses of action, marketing policies being affected by some fundamental changes in terms of increased efficiency and<br />
competitive pressure in order to adapt to the transformation in consumer behavior related to the goods carried.<br />
The economic crisis drew attention to the micro and macroeconomic indicators that behave differently depending on the<br />
social, political and financial context. Monitoring continuously the harmonized indices of consumer prices,<br />
investigating the consumption trend and the structure of consumption basket and analizing the imports and exports<br />
evolution it is possible to understand market situation and to forecast as accurately as possible future evolutions.<br />
The demand for bakery products is relatively inelastic and accordingly, manufacturing companies strategies aimed at<br />
diversification of the range and quality growth while focusing on the potential benefits to the consumer health.<br />
This paper aims to develop an diagnosis for quantitative and qualitative elements of bakery business at national level as<br />
response to the economic changes that have occurred and to highlight their reflection in the economic results obtained.<br />
Key words: bakery market, economic crisis, Harmonized index of consumer prices, turnover<br />
Crises are defined as situations characterized<br />
by a pronounced instability leading to increasing<br />
uncertainty. There are no fixed values that define<br />
an economic crisis, but recession is conventionally<br />
agreed that after two successive quarters when<br />
dealing with a lower GDP countries or regions,<br />
which usually decrease is accompanied by a<br />
decrease in individual income, reduction of<br />
employment, industrial production and<br />
consumption reduction.<br />
The major purpose of economic activity is<br />
constituted by quantitative and qualitative<br />
correlation of the food production with the<br />
consumers demand. Specific for the food products<br />
is highlighting the influence of consumption<br />
variation factors (Chiran A., et al., 2007).<br />
In this global agitated context, the<br />
companies have to learn the survival lesson and<br />
find their own way out of the crisis.<br />
The companies overcoming the economic<br />
crisis and having a successful comeback, are those<br />
with a higher adapting capacity through change.<br />
This means they have the capacity of responding<br />
quickly and effectively to a new context.<br />
Disregarding the market, sets in danger not only<br />
the recovery of the company from the crisis but<br />
also its survival (Pandelică Amalia, Pandelică I.,<br />
2010).<br />
Economic crisis since the end of 2008, has<br />
affected investments in the bakery sector,<br />
estimated at 100 million euro for 2009. Many<br />
potential investors have had to resort to loans to<br />
make investments, a possible restriction or<br />
inability to obtain credit leading to bankruptcy.<br />
Another problem faced by the bakery<br />
industry, against the backdrop of economic crisis,<br />
is that the dealers who are granted merchandise<br />
credit, in the defense of problems in obtaining<br />
credit, they are unable to pay the freight and this<br />
strongly affects the sector (Oancea Olimpia, 2009).<br />
The bakery market value in Romania is<br />
estimated at 1.8 billion € in 2012 and the number<br />
of employees in the sector is approximately 45 000<br />
and this is the reason it requires careful<br />
monitoring.<br />
MATERIAL AND METHOD<br />
The paper focuses on the national bakery<br />
market status indicating the structural changes that<br />
occured in the context of economic crisis. The<br />
statistics were processed from National Institute of<br />
Statistics, EUROSTAT, European Central Bank and<br />
Market Access Database provided by European<br />
Commision. Economic results were taken from the<br />
balance sheet of each company in order to effectuate<br />
the comparison. Methods used were scientific
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
documentation, diagnostic analysis, analysis and<br />
interpretation of statistical data.<br />
RESULTS AND DISCUTIONS<br />
The economic crisis was reflected în social<br />
but mainly in the macroeconomic financial<br />
indicator like Gross Domestic Product which has<br />
significantly decreased in 2009 (table 1).<br />
GDP growth rates în Romania as a<br />
consequence of the crisis has decreased with 6.6%<br />
in 2009, with more than 2% in regard to European<br />
Union average, after an economic growth in 2009 of<br />
7.3%.<br />
The recovery was only recorded in 2011<br />
when GDP was with 2.5% greater than the level in<br />
226<br />
2010, with 1% over the European Union average. In<br />
Romania the bakery sector has recorded significant<br />
fluctuations (figure 1).<br />
A particularity regarding romanian bakery<br />
market was the fact that even if the turnover<br />
decreased from 1582.8 mil. € in 2008 to 1260.6<br />
mil. € în 2009, the number of enterprises increased<br />
from 4477 to 4526.<br />
It is clearly highlighted the change of the<br />
turnover curve once with crisis started. The<br />
economic situation has determined also a certain<br />
change in the consumption basket, food products<br />
weighting differently in the population<br />
consumption basket (figure 2).<br />

The unstable financial situations caused<br />
more careful spendings of the population and<br />
oriented people towards saving. The food products<br />
weighted in 2010 37.3% in the consumption<br />
basket, in 2011 slightly increasing with 0.1%.<br />
Regarding the structure of this percent (37%), the<br />
Table 1<br />
statistics indicate for bread a participation of<br />
15.55% in 2010 and of 14.71% in 2011, greater<br />
weight recording only meat and milk products,<br />
situation explained by the fact that bread is a basic<br />
product and consumer expenses has to cover first<br />
the basic needs even if price is increasing (figure
3). In comparison to the price evolution for bread<br />
and cereals in the European Union Romania has<br />
recorded an harmonized index of consumer prices<br />
with more than 10% greater than the average in<br />
2012. Imports and export of bakery products were<br />
also influenced by economic crisis (table 2).<br />

The import value for bakery products both<br />
from/to INTRA-EU27 and EXTRA-EU27<br />
countries has diminished starting 2009 or recorded<br />
growth rate decreases, begining to slightly recover<br />
starting 2010 and 2011. The quantity of imports<br />
and exports has followed the same trend (table 3).<br />

Import quantity for bakery products grew<br />
only with 0.11% in 2009 related to 2008 for the<br />
INTRA-EU27 countries and has decreased with<br />
8.57% for EXTRA-EU27 countries. The exports<br />
diminished from 16499 to 15733 to in 2009 in<br />
relation to the INTRA-EU27 countries but grew<br />
with 16.8% for the same period relation to the<br />
EXTRA-EU27.<br />
The bread consumption in Romania (figure<br />
4) is 7.848 kg/person/month, being greater in the<br />
rural area (8.044 kg /person/month). An<br />
dependend variable for the bakery market is the<br />
wheat price (figure 5) which was the center of all<br />
food strategies.<br />
Figure 4 Monthly bread consumption in Romania<br />
The evolution of wheat price in Romania<br />
indicates two peaks, first in the first quarter of<br />
2008 when it reached the level of 0.84 lei/kg and
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
the second in the second quarter of 2011 when the<br />
price was 1.01 lei/kg. The fluctuations of wheat<br />
price has determined contantly direct changes in<br />
the bakery market. The main romanian bakery<br />
producers are VEL PITAR SA, DOBROGEA<br />
GRUP SA and BOROMIR PROD SA (table 4).<br />
228<br />
The economic crisis and the direct and<br />
indirect consequences determined a decrease in<br />
turnover for all three great producers in 2009<br />
related to 2008, only DOBROGEA GRUP SA<br />
recovering in 2010 with an increasing turnover of<br />
215279957 lei.<br />

CONCLUSIONS<br />
Bakery market in Romania was inluenced by<br />
the economic crisis but less than other sectors of<br />
the national market.<br />
There are not significant change in bakery<br />
consumption even if the weight in the consumption<br />
basket has slightly changed.<br />
The bread consumption in Romania is by<br />
7.848 kg/person/month, which means an annual<br />
consumption of 94.176 kg/person.<br />
Harmonized Indices of Consumer Prices for<br />
bakery in Romania is much higher than the<br />
European Union average.<br />
The economic crisis has affected Romanian<br />
imports and exports of bakery products both in<br />
volume and value.<br />

ASPECTS REGARDING THE PROMOTION OF FRUIT,<br />
VEGETABLES AND FRUIT AND VEGETABLES PRODUCTS IN ROMANIA<br />
Abstract<br />

e-mail: vasiliu_madalina@yahoo.com<br />
The horticultural products exploitation field of study is the taking over, keeping fresh and processing of the vegetables,<br />
fruits and other similar products. The valorification of fruits has economical, social (employment, diversification of<br />
industrial activities) and alimentary importance. The study of fruit growing Romanian, European and global markets, as<br />
well as the study of the ways of promotions used is an extremly complex activity that requires a very well structured,<br />
continuous and great amount of work. This fruit market research constantly pursues the production capacities and the<br />
exploitation manner of fruit products. This way the farmers are no longer seen as suppliers of raw materials but as<br />
necessary, but not central, elements of a very complex circuit. Fruit products market is a mature market, permanently<br />
and strongly affected by the favorable or unfavorable developments in demand, by permanently changing consumers<br />
needs, by competition and by the evolution of the promotion techniques and methods. Fruit products market is<br />
influenced both by its specific factors, as well as by general ones, with reference to socio-political groups.<br />
Key words: fruit and vegetable products, fruit and vegetable industry, return on investment, promotion strategies<br />
The study of Romanian, European and<br />
global wine market as well as the research<br />
regarding the promotion ways used in the industry<br />
involve a very well structured, continuous and<br />
complex work, that constanly tracks the production<br />
capacity and manner of sale of fruit products. The<br />
agricultural producers are no longer seen as raw<br />
material suppliers, but as compulsory parts of a<br />
complex circuit.<br />
Fruit market is a mature one, strongly and<br />
permanently affected by favourable or<br />
unfavourable developments in demand, by<br />
consumers need that are continously changing, by<br />
competition as well as by technology development<br />
and promotion methods.<br />
MATERIAL AND METHOD<br />
The studies have been made during 2007 and<br />
2011, using as sources of information literature from<br />
Romania and foreign sources, as well as the Internet<br />
as a tool of comparison and of real time search<br />
results.<br />
The study aimed at collecting statistical data<br />
regarding the current consumption situation, recovery<br />
and promotion of fruit, vegetables and fruit and<br />
vegetable products in Romania.<br />
1 University of Agricultural Science and Veterinary Medicine, Iasi, Romania<br />
RESULTS AND DISCUSSIONS<br />
Trees and shrubs fruits are indispensable in<br />
maintaining body health food ratio. They contain<br />
sucrose, glucose, fructose, protein, free organic<br />
acids, pectic substances, tanoide, based minerals K,<br />
Ca, Fe, Mn, Mg, Al, S, P, Si, Cl, B, Cu, etc.. , 80-<br />
85% water, essential oils, vitamins and amino<br />
acids. A very important norurishmental role is<br />
played by products derived from fruit processing<br />
such as marmalade, stewed fruit, juices, syrups,<br />
fermented beverages (cider) r), alcohol (cherry,<br />
blueberry), and dry fruits<br />
In terms of fruit market (in our country), for<br />
a clear set of knowledge there are certain aspects<br />
that should be taken into consideration:<br />
The great variety of products that provides<br />
diversified consumption, but also the<br />
impossibility of achieving production within the<br />
same geographical area;<br />
The level of very different seasonality for<br />
different product groups, resulting un uneven<br />
supply, seasonal demands while the forms of the<br />
demand are continuously changing;<br />
The high degree of seasonality which requires<br />
operative product quantity management<br />
according to consumer’s demand;<br />
Due to suitability demand, producers (bidders)<br />
provide fruits and vegetables out of the season
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
also, but as frozen or canned fruits/vegetables,<br />
juices and so on;<br />
The zonality of fruit production alongside the<br />
existence of a weak trading system determines a<br />
high level of self-consumption;<br />
The high level of perishability requires decision<br />
making in order to develop operational programs<br />
on the timing and regularity of supply,<br />
depending on consumer demand;<br />
High consumption of inputs;<br />
On family farms lack of accounting, even<br />
primary one, hinders value appreciation of the<br />
sold production;<br />
Fruits have various destinations, such as: fresh<br />
consumption, previous storage, industrialization,<br />
export and so on;<br />
The parallel existence of peasant markets<br />
alongside state owned or privately held trade<br />
companies markets;<br />
Fruits market is mainly disorganized, unhygienic<br />
and unprofitable;<br />
The failure of practicing a fiscal policy, suitable<br />
for individual private producers (due to<br />
difficulties encountered by tax base instability).<br />
230<br />
Producers organizations represent the main<br />
players of common organization of fruits and<br />
vegetables markets, whose role is to focus the offer<br />
and to adapt it to market demand. This way the<br />
producers organizations act in the interest of their<br />
members.<br />
The national strategy of Romania related to<br />
operational programs in fruits and vegetable sector<br />
is defined on a 5 years period, starting January<br />
2009.<br />
In 2011 the fruit growing area (fruit<br />
orchards) was 155,6 thousand hectares and total<br />
fruit production was of 1475,3 thousands tones<br />
(total production of orchards plus kitchen gardens)<br />
(table 1)<br />
Annual consumption of fruits and vegetables<br />
per capita in Romania is around 70-80 kilos, while<br />
the European average goes up to 90-100 kilos.<br />
From the total surface of 14.7 million<br />
hectares that was estimated in July 2011, 218.000<br />
hectares are vineyards and 206.000 hectares are<br />
orchards and nurseries (1.4%).<br />

In Romania the fruit consumption level is<br />
lower than the European level, due to the following<br />
aspects (figure 1)<br />
The self-consumption of fruits stands at over<br />
30% of the yields obtained by individual<br />
producers;<br />
The practice of fruits growing on small areas by<br />
the individual producers that own 83% of the<br />
area cultivated with vegetables and fruits;<br />
Individual producers have limited financial and<br />
material resources, as well as poor mechanical<br />
equipment, that lead to lower productivity and<br />
productive potential of land;<br />
Lack of raw materials for fruit processing<br />
industry is the main reason why it works at 45%<br />
of its production capacity, which has<br />
repercussions on the whole fruit production and<br />
on individual fruit production.<br />
Fruit trade in Romania is still disorganized,<br />
unprofitable, unhygienic and poor (in certain<br />
areas), mainly due to the congestion of the state<br />
sector and due to the incapacity of the private<br />
sector to ensure the entire demand of such<br />
products.<br />
Table 1<br />
Related to fruits and vegetables promotion<br />
and the promotion of fruits and vegetables<br />
products, the usage of techniques to promote ease<br />
the correct placement of a certain fruits of fruits<br />
products distributors on market. The result to this<br />
is an optimal recovery of products plus a very good<br />
representation of the specific company on the<br />
market.<br />
Marketing strategy must be adapted to<br />
market and to the economic and social<br />
environment, to the technological changes. There<br />
must be respected a very well defined and<br />
documented plan of the marketing campaigns.<br />
The EU is an ally in developing time<br />
scalable marketing strategies. The budgets for<br />
these campaigns are also offered by the EU.
Figure 1 Scheme of fruits and vegetables chain<br />
This way the fresh fruits and vegetables<br />
producers can benefit from the decision taken by<br />
the EU comission the 24 of April 2010, that<br />
distributes aid between member states through the<br />
School fruit consumption program. The program<br />
lasts between the 1 st of August 2010 and the 31 of<br />
July 2011.<br />
Bulgaria, Cyprus, Denmark, Hungary, Italy,<br />
Malta, Portugal, Romania, Slovakia and Slovenia<br />
have already communicated the commission their<br />
desire to participate in the EU program as well as<br />
to use more than the initial allocation of aid.<br />
Austria, Belgium, Czech Republic, Estonia,<br />
France, Germany, Greece, Ireland, Latvia,<br />
Lithuania, Luxembourg, Netherlands, Poland,<br />
Spain and the United Kingdom have also<br />
communicated their desire to participate in the<br />
program, but using the allocated resources only<br />
(table 2).<br />
Strategies to promote fruit products:<br />
reflect business relations with different agents;<br />
give an insight of the dynamic business position<br />
/ structure / changes / requirements and the<br />
market competition;<br />
take into account the trading systems used by the<br />
company.<br />
There are several types of strategies to<br />
promote fruit and food products in general:<br />
Mass marketing strategy(undifferentiated);<br />
Focused marketing strategy (differentiated);<br />
Offensive strategy;<br />
Defensive strategy;<br />
Self promotion strategy;<br />
Promotion through specialized agencies<br />
strategy;<br />
Price competitiveness strategy;<br />
Without price influence competitiveness<br />
strategy.<br />

Common mistakes in marketing strategies<br />
are:<br />
Repeat the strategy from previous years without<br />
updating it to the new condition;<br />
The venture into the unknown by applying<br />
completely new solutions.<br />
Successful strategies are those which<br />
determine the market opportunities and<br />
competitive advantage, based on the results of<br />
marketing control. These strategies reveal risks,<br />
favorable circumstances, strengths and weaknesses<br />
of the organization.<br />
By translating them into practice it leads to<br />
needing to be created such a relationship system<br />
between enterprise and environment to ensure its<br />
placement in a good position when dealing with<br />
competitors.<br />
A successful strategy marks a defining<br />
period in the life of the company. This reflects the<br />
fact that there have been adopted the best decisions<br />
regarding the consumer and the ways in which his<br />
needs are met.<br />
Such a strategy indicates the essential aim<br />
on a certain period of time, the plan that will be<br />
used to accomplish these purposes and the answers<br />
to the fundamental questions:<br />
What needs to be produced and what products<br />
will be introduced in manufacturing;
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
Which is the market share that needs to be<br />
targeted by each product;<br />
Up to what level can the prices level grow;<br />
What needs to be communicated to the market<br />
segment;<br />
Which is the best distribution channel for a<br />
certain product.<br />
CONCLUSIONS<br />
EU Agriculture Ministers agreed in June<br />
2007 to reform the CMO for the fruits and<br />
vegetables sector. The sector policy must meet<br />
market requirements by reducing price fluctuations<br />
and the imbalance between supply and demand and<br />
to encourage the fruits and vegetables consumption<br />
while ensuring the competitiveness of products.<br />
In order to encourage the sale of fruit and<br />
vegetables a structured approach to promoting is<br />
needed. Promotion of fruit and vegetables has a<br />
lasting impact on consumption and is one of<br />
important measures that producer organizations<br />
must achieve.<br />
232<br />
Promoting the consumption of fresh fruit<br />
should be a national consumer campaign while<br />
derived products and wine products may take the<br />
brand campaign level depending on the target<br />
audience.<br />

ROMANIA’S INNOVATION CULTURE: THE QUEST FOR THE<br />
DEPENDENT VARIABLE<br />
1 Alexandru Ioan Cuza University of Iasi, Iasi, Romania<br />
Sabina Cristiana NECULA 1<br />
e-mail: sabina.mihalache@feaa.uaic.ro<br />
The present paper treats the problem of innovation culture. We try to identify the main variables that influence the<br />
innovation culture. We make use of current data available in the research field by appeal to the literature and concrete<br />
data from European Union report data. We are putting the focus on Romania and we are trying to discuss the historical,<br />
the geographical, and the economical premises that determine these variables. We discuss about entrepreneurial<br />
activities, public sector investments in research and development, the appetite for risk, uncertainty avoidance, the taste<br />
for wisdom and mediocrity. We treat also the problem of an historical horizontal shape of Romania’s destiny, full of<br />
compromises in the present, with lack of specialized culture. After this we discuss historical-political factors by<br />
appealing the subject of collectivism versus individualism and we stress the fact that although for our country it is best<br />
suited the spirit of collectivism and we were even put in our history to live in collectivism the gene of our country is an<br />
individualist one with no antrepreneurial spirit. We conclude the present paper by identifying a possible model of<br />
variables that we consider they influence our innovation culture.<br />
Key words: innovation culture, Romania’s innovation culture, R&D, saeculum<br />
The starting point for this paper is the quest<br />
for the dependent variable of Romania’s<br />
innovation culture. We try to identify the main<br />
reasons, or otherwise saying the main variables<br />
that influences what we will try to define as<br />
innovation culture and its meaning for Romania. If<br />
there is alot of evidence by which someone can<br />
admit that the taste for entrepreneurship, the will<br />
for making business and assuming risk is very low<br />
in Romania one can argue that Romania has a great<br />
potential in being innovative.<br />
We have alot of references which states that<br />
Romania’s culture is a minor one (Cioran, 1990,<br />
Patapievici 2007). In this country every gesture,<br />
every action, and every attitude is an absolute<br />
beginning. There are no constancies, rules or<br />
directives. No one is preceding us, no one is<br />
encourages us, and no one is helping us (Cioran,<br />
1990).<br />
The formal shape of our destiny is an<br />
horizontal one. We have not lived our gothic spirit.<br />
We suffer from: passivity, skepticism, self<br />
contempt, gentle contemplation, minor religiosity,<br />
un-history, and wisdom. We have a past full of<br />
humiliations and a present full of compromises.<br />
A people which has no political spirit misses<br />
the way to the nation and a structural change based<br />
on collective orientation is necessary.<br />
The Romanians love changing to one<br />
hundredth and eighty degrees, meaning the<br />
inconstancy in the process of things.<br />
Imitation is mandatory for cultural progress,<br />
but the imitation must happen by taking into<br />
consideration the saeculum (Lovinescu, 1923-<br />
1926). But the problem remains in identifying the<br />
main characteristics of this saeculum. Could it be<br />
the technological progress? Or maybe<br />
globalisation? Or perhapse the simple mediocrity?<br />
We will discuss in the next section the main<br />
method and material used for this paper. In the<br />
second section we will discuss the main results. In<br />
the end of the paper we will draw some plausible<br />
conclusions.<br />
METHOD AND MATERIAL<br />
Our research method is a calitative one. We<br />
will identify some qualitative factors that we think they<br />
influence the innovation culture. The material used is<br />
based on empirical data and facts about Romania’s<br />
innovation policies, innovation key indicators, and<br />
innovation cuture. The proposed research model is<br />
presented here therefore (figure 1).

versus local development<br />

Mediocrity<br />
RESULTS AND DISCUSSIONS<br />
Innovation culture is to be understood in<br />
terms of attitudes towards innovation, technology,<br />
exchange of knowledge, entrepreneurial activities,<br />
business, uncertainty (Hofstede 2001), and related<br />
behaviour and historical trajectories.<br />
Herbig and Dunphy (1998) define culture,<br />
Hofstede presents a more definite and less flexible<br />
conception of culture, Brons (2006) looks into<br />
different definitions of culture but all conclude that<br />
culture is a sum of values and beliefs that<br />
distinguishes people of one nationality to another.<br />
Hofstede has a model of national culture with four<br />
dimensions: power distance, individualism,<br />
masculinity, uncertainty avoidance, and long-term<br />
orientation.<br />
The concept of „culture of innovation” is<br />
often overlaped with the concept of „business<br />
culture” with all the meanings that one can draw<br />
from that.<br />
But there are other considerents to take:<br />
„most people work in hope of reward” no matter<br />
the taste for risk of the nation to which they<br />
belong, religion is an important considerent in<br />
discussing the concept of innovation culture, and<br />
even the taste for skeptisicm and wisdom is an<br />
important factor.<br />
What about Romania? We have a history of<br />
resistance, one of deffending our teritory, to treat<br />
our political co-regional neighbours with<br />
extremely carrefull and wisdom policies, with<br />
compromises and we are known to be different in<br />
this part of the Balcan region.<br />
Facts supporting the factors derived from<br />
political spectrum<br />
At present, Romania does not have a<br />
National Innovation Strategy to define clear<br />
innovation policies and priorities. Therefore,<br />
innovation policies are addressed in some of the<br />
programmes of the 2007-2013 National RDI Plan.<br />
Figure 1 The research model<br />
234<br />
Innovation culture<br />
Public procurement for innovation and precommercial<br />
public procurement do not exist in<br />
Romania.<br />
The connection research-developmentinnovation-standardization<br />
is poorly developed.<br />
Lead market initiatives are very incipient in<br />
Romania.<br />
Support to open innovation and usercentered<br />
innovation are not developed.<br />
These facts conclude the main idea that our<br />
innovation culture is not a specialized one and it is<br />
only derived from a general framework.<br />
The main recommendations concerning<br />
research-development-innovation (RDI) policies<br />
that we consider necessary are:<br />
1. Strengthening the performance of the RDI<br />
system and its capacity to meet socio-economic<br />
needs<br />
2. Stimulating private RDI investment<br />
3. Developing the European dimension of RDI<br />
policies and programmes<br />
Evidence on effectiveness of innovation<br />
policy:<br />
- Poor policy prioritization<br />
- Strong disconnect between the science system<br />
and the production system<br />
- Mismatch between the allocation of RDI funds<br />
and the areas of national comparative advantage<br />
- Fragmentation and large number of public R&D<br />
institutes in a wide range of scientific fields and<br />
sub-optimal allocation of resources<br />
- Limited implementation oversight<br />
- Unpredictable budgeting given the fiscal crisis<br />
and uneven patterns of funding<br />
- Rigid budgeting and human resource<br />
management rules<br />
- Frequent changes in personnel<br />
- Weak incentives for performance<br />
- A confused legal framework and a plethora of<br />
actors with unclear coordination roles
- Competing for budget resources having different<br />
institutional priorities<br />
- A heavy concentration of funding in the early<br />
stage of the innovation value chain was<br />
identified, while the later stages (product<br />
development and product launch) are severly<br />
under-funded and largely ignored by the<br />
government.<br />
The Word bank’s Functional Review<br />
provides four main recommendations:<br />
1. Strengthen the governance of the RDI system<br />
2. Strengthen the performance of R&D activities<br />
within the public sector itself<br />
3. Accelerate the translation of R&D into<br />
innovation in the private sector<br />
4. Increase the level of private sector R&D<br />
The national strategy should focus on<br />
innovation investment. Because people perform<br />
innovation, all stakeholders in improving<br />
innovation need to focus on creating innovators.<br />
Developing new generations of talent takes time,<br />
as does regenerating our innovation pipeline that<br />
started to become less fit in the mid-1990. The path<br />
to return us to our innovation economy requires<br />
long sustained investments that support iterative<br />
innovation and create innovators as we<br />
concomitantly downsize inefficient government<br />
expenditures.<br />
The growth in R&D relative to economic<br />
output after World War II, and especially in the<br />
1980s, can be attributed to a number of important<br />
changes. The transition to a “knowledge-based<br />
economy” (OECD, 1999) or to “knowledgesocieties”<br />
(Mansell et al. , 1998) is a widely<br />
accepted phenomenon in developed countries, and<br />
has become a target for developing and transitional<br />
economies. The growth in R&D intensity is often<br />
cited as one of the indicators of the emerging<br />
knowledge economy, but additional indicators,<br />
independent of R&D, also point in the same<br />
direction. There has been an increase in the<br />
knowledge content of production, especially in the<br />
developed economies, over time, skills have<br />
become more important in production and<br />
education levels have risen. Industries with a<br />
strong science base, such as chemicals,<br />
pharmaceuticals, electronics and aerospace, have<br />
grown in relative importance while other<br />
industries, such as automobile production, have<br />
incorporated more science-based elements. For<br />
example, computerized components have become<br />
prevalent in new automobiles. Thus, many<br />
economies have experienced a tendency for the<br />
portion of value added related to skills and<br />
knowledge applications to rise. And this implies a<br />
need for more R&D to pursue further advances in<br />
knowledge.<br />

Facts supporting the factors derived from<br />
global versus local development<br />
Romania is the second smallest among the<br />
member countries of the European Union<br />
regarding research and development spending<br />
show the European statistics office, Eurostat.<br />
The latest European Innovation Scoreboard<br />
presents Romania as one of the modest innovators<br />
with a below average performance (http://www.<br />
proinno-europe.eu/inno-metrics/ page/romania).<br />
Relative strengths are in Finance and<br />
support and Outputs. Relative weaknesses are in<br />
Open, excellent and attractive research systems,<br />
Linkages & entrepreneurship, Intellectual assets<br />
and Innovators.<br />
High growth is observed for Public R&D<br />
expenditure, Community trademarks and<br />
Community designs. A strong decline is observed<br />
for Non-EU doctorate students. Growth<br />
performance in Finance and support and<br />
Intellectual assets is above average. In the other<br />
dimensions it is below average.<br />
The performance of Bulgaria, Latvia,<br />
Lithuania and Romania is well below that of the<br />
EU27. These countries are Modest innovators.<br />
Bulgaria and Romania are the growth<br />
leaders of the Modest innovators. We present the<br />
average annual growth in innovation performance<br />
(figure 2). The performance of the four country<br />
groups across the different dimensions is shown<br />
bellow (figure 3). The annual average growth per<br />
indicator and average country growth is presented<br />
bellow (figure 4).<br />
Important measures to consider:<br />
- A better prioritization of RDI themes in close<br />
connection with the areas of national<br />
comparative advantage<br />
- Increasing the RDI capacity of Romanian<br />
enterprises (both SMEs and large firms)<br />
- Introducing an innovation culture in the<br />
economy<br />
- Better support to and monitoring of innovative<br />
and high-growth firms<br />
- Better support for entrepreneurship<br />
- Improved technology transfer infrastructure and<br />
qualified personnel in universities.<br />
Facts supporting the psichological factors<br />
From the data available and presented above<br />
anyone can draw a simple conclusion: Romania<br />
has alot of potential but her taste for skepticism<br />
and her appetite for wisdom are some<br />
psichological factors that influence what is called<br />
national culture.<br />
The only important measure to consider here<br />
is focusing on a culture of innovation at the<br />
individual level of citizen.

CONCLUSIONS<br />
Culture is learned. For a person this means<br />
education and for a nation this means adaptation to<br />
continual changes derived from the economical<br />
and geo-political medium. The main conclusions<br />
that can be drawn are that the investment in<br />
education, in R&D, in thinking a general<br />
framework for long-term for innovation policies<br />
could be the main considerents in supporting a<br />
nation’s innovation culture. The title of our paper<br />
poses a question, which has to be answered.<br />
We have learned that there is a reliable link<br />
between cultural dimensions and innovation<br />
policies. However, although culture undoubtedly<br />
plays an important role in innovation policies<br />
development, it should be stressed that the<br />
relationship is not straightforward and culture is<br />
not a sufficient factor for getting a notable outcome<br />
in having good innovation policies, indicating the<br />
need for further analysis.<br />
We have found that to be successful in<br />
innovation culture, a nation should have lower than<br />
average the level of skepticism, the appetite for<br />
risk. The relationship is a direct on with an inverse<br />
effect. Also, we have learned that we need a better<br />
specialization of culture. We have alot of general<br />
specializations and to be sincere we have alot of<br />
general in everything.<br />
The third level of factors indicated that our<br />
historical premises show us as being individualists<br />
with some anarhic influences but we liked to live<br />
in collectivism due to our low appetite for risk.<br />

PROCESS INNOVATION IN THE ROMANIAN PUBLIC ADMINISTRATION.<br />
OBSERVATIONS AND RECOMMENDATIONS<br />
Abstract<br />
1 „Alexandru Ioan Cuza” University, Iasi, Romania<br />
Daniela POPESCUL 1<br />
e-mail: rdaniela@uaic.ro<br />
This paper aims to analyze the degree of innovation of processes in the Romanian local public administration. In a first<br />
instance, we have mirrored, on the one hand, the positive connotation unanimously credited to innovation (summarized<br />
by the truism “innovation generates progress, economic growth and a better quality of life”) and, on the other hand, the<br />
blames of bureaucracy and enclosure traditionally addressed to local public agencies (normally regarded as noninnovator).<br />
Starting from this apparent set, we have analyzed the modification the information and communication<br />
technologies brought to the 41 city halls which are now present virtually. We have also noticed changes facilitated by<br />
the internet and web technologies regarding the payment of taxes and duties, filling in forms, booking services<br />
(marriages, public hearings, etc.), the delivery of information, and the relationship with citizens. Finally, according to<br />
this information, we have come to several conclusions and recommendations in order to increase process innovation in<br />
local administration.<br />
Key words: process innovation, public administration, interaction between public administration and citizens<br />
As we have detailed in Popescul (2011), the<br />
connotation credited to innovation, both at the<br />
organisational and at national or global levels, is<br />
imperatively positive. In the terms used by<br />
Sánchez and Rodríguez (2009, p. 384), „it has<br />
become a compulsory reference both in the<br />
economic analysis manuals and for the justification<br />
of different public policy actions promoting<br />
innovation and research, the positive effects on the<br />
economic growth and development of companies<br />
(income increase, new improved products<br />
enhancing the quality of life, a greater sensitivity<br />
to these products, etc.) and to the increase of the<br />
quality of life.” The authors observe that the Green<br />
Paper was the first underlying the social trait of<br />
innovation (seen as a mechanism expressing<br />
creativity and necessities correlated to the most<br />
important current issues and which should mostly<br />
allow us improve the living conditions and<br />
determined a sustained development) citing<br />
Mokyr (1990) for the support of their statements,<br />
according to whom innovation increases the total<br />
volume of knowledge belonging to society and,<br />
implicitly, its productive capacity (quantitative and<br />
qualitative) i.e., the economic growth and its<br />
capacity to regenerate well-being. Du Plessis<br />
(2007) draws the attention on the increasing<br />
complexity of innovation seen as a phenomenon<br />
which changed the actual nature of economic<br />
growth as well as on the race for novelty which<br />
seems to be one of the constant elements of the<br />
contemporary economic life. The positive impact<br />
of innovation on the economic growth of a nation<br />
or region (or on the competitive benefit, the market<br />
share or dimensions of the organisation), the<br />
complexity and the rhythm of innovation processes<br />
are considered by Markatou (2011) to be the<br />
reasons why scientific papers and articles<br />
belonging to the general business media on this<br />
subject are so abundant. Sententiously and<br />
truistically, Dumitrachi et.al. (2006, p. 39) states<br />
that „innovation is one of the main factors leading<br />
to economic well-being”, while Page (2012, EG),<br />
bringing into discussion the Solow model,<br />
demonstrates even that no economic growth could<br />
be possible without innovation. Dayer, Gregersen<br />
and Christensen (2011, p. 1) talk about innovation<br />
as being the blood flow of global economy, the<br />
power which radically change industries and<br />
generate well being. A measurable proof of the<br />
positive impact of innovation on various levels is<br />
brought by a study undertaken by General Electric<br />
in 2011 (GE, 2011), where they interviewed 1000<br />
top managers from 12 countries, all of them being<br />
involved in innovation, showing, almost<br />
unanimously, that innovation is considered to be<br />
the hope for a more prosperous and competitive
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
economy, more new jobs and for enhancing<br />
people’s lives, in general.<br />
The above observations usually stand for the<br />
private sector and specially refer to product<br />
innovation. While discussing about processes in<br />
local public administration, we can observe a<br />
certain ideological stiffness identified by Brătianu<br />
(2011, pp. 521-524) as an „innovation killer”, by<br />
excessive bureaucracy and are generally seen as<br />
non-innovator. The author shows that innovation<br />
and knowledge creation have been systematically<br />
discouraged during the socialist period, and then<br />
the only admitted source of knowledge and new<br />
ideas was the communist party. As a consequence<br />
of the lack of competitiveness in the centralized<br />
economic system, the employees were not<br />
encouraged to involve in innovator activities. This<br />
continues, inertial and residually, even today. In<br />
the same study the cited author notices that<br />
bureaucracy has achieved clearly negative<br />
connotations due to its application without limits<br />
during the communist period. Its excessive rules<br />
were implemented to support control and the<br />
resulting structures, hardened especially in the<br />
public administration and still persisting, kill any<br />
interest for innovation, change or new knowledge.<br />
The inherited hierarchies, where the advantages<br />
were directly proportional with the occupied<br />
position still generate, even today, corruption and<br />
underground rewarding systems, far from<br />
meritocracy, and discourage innovation. Adding to<br />
all those traits identified above the absence of<br />
financing, linear thinking, mechanical patterns<br />
based on cause-effect (which discourage<br />
innovation, creativity, diversity of opinions), the<br />
lack of cooperation between organisations, the lack<br />
of spaces for sharing experiences and the<br />
insufficient resources (especially human), we can<br />
design a less happy picture of the Romanian public<br />
administration.<br />
To reconciliate the two sets of opposing<br />
opinions, we tried to identify the way the<br />
traditional processes regarding the interaction of<br />
citizens with the city halls have modified as a<br />
consequence of their presence in the virtual space,<br />
through internet, itself a radical innovation, which<br />
substantially changed our lives as well as by Web<br />
technologies.<br />
MATERIAL AND METHOD<br />
In April 2012, we developed, by means of<br />
direct observation, a study for the 41 websites<br />
belonging to the city halls (including Bucharest City<br />
Hall). The importance of the analyzed websites derive<br />
from the fact that they address, directly or indirectly,<br />
to approximately 7.872.986 inhabitants of the urban<br />
area („indirectly‖ because the data taken from the<br />
240<br />
National Statistics Institute website also include<br />
children), who represent 37% of the total Romanian<br />
population. In this study we wanted to reveal the<br />
types of activities traditionally offered by the city hall<br />
which have been opened to the public by means of<br />
their websites, the form of presenting the information<br />
necessary to the public, as well as to identify the<br />
means of real-time interaction with citizens, and the<br />
level of representation of city halls in Web 2.0.<br />
Furthermore, we will present the main findings of the<br />
study.<br />
RESULTS AND DISCUSSIONS<br />
The main processes “renewed” by their<br />
“movement” into the virtual environment of the<br />
city halls are the following:<br />
Payment transactions of debts to the local public<br />
administration;<br />
Filling in forms;<br />
Searching for documents (functioning<br />
certificates, of taxi companies etc.);<br />
Booking city hall services (hearings, marriages<br />
etc.);<br />
Information delivery;<br />
Discussing with citizens.<br />
With reference to the payment of local<br />
taxes and duties, we have noticed that the<br />
payment at the counter is replaced, partially or<br />
totally, by the electronic payment. The forms vary<br />
from very basic ones (loading the scanned payment<br />
document issued by a bank on the website of the<br />
city hall) to those which are largely accepted in the<br />
business area – card payment or electronic<br />
payment. The main types of virtual payment offices<br />
for local taxes and duties are the following:<br />
1. Joining the Online Banking Payment<br />
National System (www.ghiseul.ro). This form is<br />
more common in 50% of the analyzed city halls<br />
(having to mention that some of them, on the date<br />
when the website was accessed, did not show on<br />
their website the possibility of payment through<br />
ghiseul.ro, the data being collected directly from<br />
this website). Some city halls also use their “old”<br />
application, which we appreciate as being positive<br />
in terms of comfort for the citizen who is already<br />
familiar with it;<br />
2. Applications developed by their own<br />
resources with different forms – E-clerks with<br />
structured menus, which help the user get informed<br />
on the activity of the city hall and be able to access<br />
links for payments, other applications with varied<br />
structures, where the authentication is either<br />
performed through the personal numerical code<br />
(for citizens) or the registration code (for<br />
companies), or with an account and a password<br />
requested online or in person, at the counter of the
agency. Applications can be found on 34% of the<br />
websites.<br />
In few cases (17%), electronic payment<br />
applications either do not exist or are not<br />
functional.<br />

payment (2012, in the city halls, municipal city<br />
residences)<br />
Downloading scanned forms in PDF or MS<br />
Word is very popular on most of the visited<br />
websites, with only one exception (Miercurea Ciuc<br />
City Hall, www.szereda.ro). The offered forms are<br />
different from one city hall to another and the role<br />
of posting them is to minimise the time lost at the<br />
counter – the time is decreased through the simple<br />
completion of the form after printing it from the<br />
website. We appreciate that this is not the best<br />
way, as long as citizens still use their pens to fill in<br />
the printed forms, take the document to the city<br />
hall or scan it and send it by email, and, obviously,<br />
the data will be processed by a clerk into the<br />
information system of the city hall.<br />
Online searches for all types of documents<br />
(usually for previously filled certificates or<br />
requests) are present on at least 30% on the<br />
analysed websites and perfectly substitutes, on our<br />
opinion, a phone conversation of citizens with the<br />
city hall or a visit to the city hall.<br />
The reservations for hearings, marriages,<br />
documents etc. are present on at least 21% of<br />
websites, and the online petitions can be found on<br />
approximately 10%.<br />
The great majority of information is<br />
offered as hypertext, being accessible by means of<br />
structured menus differing from one website to the<br />
other. The information is varied and sufficient,<br />
updated and presented in an attractive manner. A<br />
good merit should also be granted to the photo<br />
galleries, with representative images of the city.<br />
The video information is offered only by 20% of<br />
the websites, and one city hall (Târgu Mureş)<br />
manages its own YouTube channel. The live<br />
broadcasting web cams are to be found on<br />
241<br />
Lucrări Ştiinţifice – vol. 55/2012, seria <strong>Agronomie</strong><br />
approximately 30% of the websites, digital<br />
interactive maps on 70% of the analysed websites.<br />
Forms of virtual interaction with citizens<br />
on the analysed websites are:<br />
Forums, in 34% of cases. Unfortunately, not all<br />
forums are well maintained and part of them are<br />
not updated (in the sense that citizens didn’t not<br />
receive answers to their questions from the<br />
official representatives but from ... other<br />
citizens) and the spam are many;<br />
Suggestions and complaints pages which can be<br />
filled online;<br />
Messaging, either directly to the site or by email<br />
(all websites offer an email address at contact, in<br />
the diagram in figure 2 the area „Email<br />
messages” refers to those websites having this<br />
modality as the only method of interaction);<br />
Connexion to www.domnuleprimar.ro, website,<br />
which is a place for dialogue with the mayors of<br />
any registered city hall.<br />
The scales we calculated for the above types<br />
of interaction of citizens with the mayors are<br />
visible in figure 2.<br />
Figure 2 Virtual interaction with citizens (2012,<br />
municipal city residences)<br />
Analysing the website of several city halls<br />
we have noticed they actually lack on Web 2.0<br />
specific social networks (like Facebook, Twitter,<br />
You Tube, blogs etc.) – which is also visible in<br />
figure 3.<br />
Taking for example Facebook, one of the<br />
most popular social networking platforms and<br />
analysing the pages of those city halls present on<br />
this environment (identified as “X city hall” or<br />
“The city Hall of municipal X”, not to create<br />
confusions with the pages of cities), we obtained<br />
data partially confirming the observations on the<br />
websites of the city halls, in the sense that the<br />
official Facebook pages are appreciated whenever<br />
some clerk has a job task to update it. The rest of<br />
pages were either automatically created, as a<br />
consequence of an employment post from the<br />
employees, Facebook users, and received random
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
likes (having no content) or as individual pages,<br />
inaccessible without the prior consent of the owner<br />
or without being updates and far from being an<br />
official page of a public agency, from our opinion.<br />

*the percentage of inhabitants pressing the ‚Like’ button<br />

There is a huge discrepancy between the<br />
number of inhabitants served by the city halls and<br />
the number of “Likes” on the Facebook page of the<br />
city hall (see Table 1, where we showed the<br />
information on pages with at least 10 “Likes”)<br />
which is relevant. In our opinion, public<br />
administration agencies should consider the<br />
openness towards the citizens also in these<br />
environments, currently more and more popular,<br />
and extremely visited especially by younger users.<br />
The web pages belonging to the analyzed<br />
city halls have also shown other services offered to<br />
users – such as survey questionnaires, blogs, online<br />
media (adaptable to mobile devices, in Timisoara),<br />
virtual tours, etc.<br />
CONCLUSIONS<br />
Following the observations gathered from<br />
the website of the 41 city halls, we have the<br />
following conclusions and recommendations:<br />
1. We can talk about innovation within the<br />
interaction with citizens due to the movement of<br />
242<br />
city halls towards the virtual environment.<br />
Innovation is incremental, in our opinion, in the<br />
sense that it does not decisively, radically modify<br />
the activity of city halls, but enhances citizens’<br />
comfort enabling them to undertake several<br />
activities from home, with a minimum time due to<br />
the internet;<br />
2. Some city halls are more innovative that<br />
others. Our intuition is, as in the Romanian saying<br />
“a good farmer makes a good farm”, the difference<br />
lies between the human qualities of the employees<br />
of the city hall. In order to improve the innovation<br />
capacity of the agency, the city hall leadership<br />
shall cultivate associative thinking, permanent<br />
interaction with people, things, information,<br />
unprejudiced observation of the surrounding world,<br />
asking questions and finding answers destroying<br />
patterns, the “local optima” in problem solving –<br />
together, these traits form what Dayer, Gregersen<br />
and Christensen (2011) call the innovator’s DNA.<br />
In order to achieve this, the city wall working<br />
environment should be relaxed, allowing the<br />
employees to be curious and open to novelty. The<br />
calculated chaos is a good solution – creative ideas<br />
come to the light when people are encouraged to<br />
think differently, to have a different approach and<br />
make changes;<br />
3. The city halls seem not to collaborate and<br />
share new means of interaction with citizens. The<br />
possible explanation probably lies in the noncompetitive<br />
environment where they function.<br />
Although there have been some very interesting<br />
initiatives (online media adapted for mobile<br />
devices, their own YouTube channel, etc.), they<br />
are completely isolated. The unanimously adopted<br />
solutions are simple and ineffective, such as<br />
scanning the documents and upload them as PDF –<br />
although a cheap and simple alternative, such as<br />
loading MS Word documents followed by the<br />
export of the data filled in towards a database,<br />
fails to be used. Innovation and using new<br />
technologies do not depend only on individual<br />
factors but also on the interaction and synergy of<br />
various factors while innovator activities require an<br />
innovator environment needing to mutually share<br />
staff, scientific and technological knowledge<br />
specialized services and innovator stimuli. Both<br />
organisationally and nationally, a co-operative and<br />
collaborative culture is an absolute must for the<br />
transfer of knowledge between individuals and<br />
groups. Without the right mechanisms encouraging<br />
cooperation, the structured or technological<br />
interventions of knowledge transfer may be not<br />
functional;<br />
4. The city halls are not visible enough on<br />
Web 2.0. We recommend that the environments of<br />
this type shall not be ignored (according to the
newest estimations, Facebook includes over 7,5<br />
millions Romanians!). In Web 2.0, the<br />
environment itself may remodel and renew the<br />
message, making it attractive in form for a certain<br />
target audience never addressed before.<br />
The success and progress recipe to improve<br />
the relationship with citizens by means of websites<br />
include, we believe, a correct financing, a<br />
sustained, coherent and steadfast management of<br />
innovation, partnerships with other similar<br />
agencies and with the public sector. The constant<br />
intensification of these parameters may lead to the<br />
transformation of city halls from isolated island to<br />
network hubs of free transferable knowledge<br />
generating, by division, innovations supporting the<br />
public sector.<br />

From all forage crops, which together with meadows have a major contribution in ensuring the forage base,,<br />
alfalfa crop (Medicago sativa L.) occupies a position of great importance. This plant is distinguished by its forage value,<br />
high cultivation area and high digestibility, and from the point of view of farmers and world's agricultural sciences is<br />
considered to be the "Queen of Fodder Herbs". In order to determine the quality of alfalfa, a series of classical analysis<br />
for cellulose, NDF, ADF and ADL were performed. This paper proposes a simple and nondestructive technique for rapid<br />
determination of these organic substances, method called „Near Infrared Spectrophotometry” (NIRS). In this purpose<br />
samples of alfalfa (Medicago sativa L., variety Eugenia) were obtained at the Experimental Teaching Station, Mănăştur<br />
and Cojocna Farm, in the years 2008-2009. Alfalfa crop was seeded by randomized block method with two experimental<br />
factors. The highest content of crude fiber, NDF and ADL was recorded on the phenophase of seeds formation (33.21%,<br />
70.31% , respectively 15.15%). The lowest content recorded (31.14%) was the ADF content during the phenophase -<br />
seed formation. Good results (successful results) were obtained for the calibration of NIRS device (SEP = 1.058 [CF],<br />
0964 [NDF], 1041 [ADF] and 1209 [ADL]). This system allows us to use NIRS technique for determining organic<br />
matter derived from alfalfa to feed and for other feed quality determination.<br />
Key words: NIRS, alfalfa, crude fiber, NDF, ADF, ADL.<br />
On the current agricultural vision, fodder<br />
production obtained from the permanent grassland,<br />
temporary grassland and forage crops, is an<br />
integral part of agricultural land management<br />
[Dale, 2011]. A fair assessment regarding the<br />
quality of forage grass originating from meadows<br />
requires an overall analysis on the data regarding<br />
the botanical composition of pastures, the nutrient<br />
and mineral content and digestibility of fodder<br />
produced [Rotar et al, 2005]. From all forage<br />
crops, which together with meadows have a major<br />
contribution in ensuring the forage base,, alfalfa<br />
crop (Medicago sativa L.) occupies a position of<br />
great importance. This plant is distinguished by its<br />
forage value, high cultivation area and high<br />
digestibility, and from the point of view of farmers<br />
and world's agricultural sciences is considered to<br />
be the "Queen of Fodder Herbs".<br />
From agrobiological point of view, alfalfa<br />
gathers a number of particularities: resistance to<br />
drought and low temperatures, good revaluation of<br />
irrigation water, high capacity for regeneration<br />
after mowing, high rate of competitiveness [Rotar,<br />
1993]. According to archaeological information or<br />
68 Université de Liège, Gembloux<br />
69 University of Agricultural Sciences and Veterinary Medicine (USAMV) Cluj-Napoca<br />
ancient philosophers writings, Medicago sativa L.<br />
crop has been taken in culture with 4000 years î.c.<br />
in regions of southwest Asia. Over the actual<br />
territory of our country, alfalfa was grown at first<br />
in Transylvania and on the late eighteenth century<br />
in Banat. Alfalfa has a great economic importance,<br />
illustrated by its high ecological plasticity, high<br />
production recorded, of more than 50 t/ha green<br />
mass/3 sewn, in natural conditions and over 80 t/ha<br />
green mass/4 sewn under irrigation, or between 10-<br />
15 t/ha of hay, and also by its high digestibility.<br />
This paper proposes a simple,<br />
nondestructive and elegant technique for<br />
determination of quality parameters (crude fibre,<br />
fibre detergent neutru [NDF], fibre detergent acid<br />
[ADF], lignine [ADL] ), method called „Near<br />
Infrared Spectrophotometry” (NIRS). Crude fibre<br />
is the most common polyglucide composed of<br />
glucose residue from the plant world, being the<br />
main component of cell walls. It presents a<br />
macromolecular, homogeneous polyglucide,<br />
consisting of several scrap β - D - glucopiranosis,<br />
united by ties β-1, 4 glycosidic bonds. Crude fiber<br />
is found together with a several number of
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
substances encrusted: lignin, hemicellulose,<br />
pectins, resins, minerals, etc.. [Diaconescu et al,<br />
2007]. NDF is the amount of protective substances<br />
obtained from residue after boiling a fodder sample<br />
in neutral detergent solution. NDF residue, actually<br />
contains very little pectic substances, but may<br />
contain negligible amounts of products like starch,<br />
nitrogenous substances and tannins [Jarrige et al,<br />
1988]. The amount of protective substances<br />
residue obtained after boiling the sample feed with<br />
detergent solution is called ADF. ADF content is<br />
regularly higher than the crude fiber from forage,<br />
these features being closely related, since both are<br />
an estimate of the amount of cellulose + lignin.<br />
[Jarrige et al, 1988]. NIRS method allows a large<br />
number of repetitions, has accuracy and high<br />
precision [Dale et al., 2012]. Also, because it is<br />
based on the use of chemicals without the need for<br />
preliminary preparation of samples, is considered<br />
to be a "clean technology" – supporting sustainable<br />
agriculture dogmas. [Vidican et al., 2000].<br />
MATHERIAL AND METHOD<br />
Alfalfa samples were obtained from the<br />
Experimental Teaching Station Mănăştur - Farm<br />
Cojocna in 2008-2009, from experience with alfalfa<br />
which was established using randomization blocks<br />
method and two experimental factors (mineral<br />
fertilization and period of harvest). Alfalfa (variety<br />
Eugenia) was sown in spring 2007 and fertilized<br />
with chemical fertilizers in different compositions,<br />
depending on the doses proposed for each variant.<br />
The first variant of this experience, the controlvariant<br />
was kept with the natural fertility of the soil.<br />
To assess the quality of alfalfa forage , laboratory<br />
samples were obtained by dividing the analytical<br />
(in the amount required by method) and chemical<br />
control was performed (crude fiber, NDF, ADF and<br />
ADL). Each quality parameter mentioned above<br />
was analyzed both by classical determinations:<br />
Weende (cellulose) method and Van Soest method<br />
(NDF, ADF and ADL) and modern determination<br />
(NIRS). This paper aims to highlight the<br />
determination of quality parameters using NIRS<br />
analysis and the results are based on data<br />
obtained by classical analysis. For NIRS technique<br />
samples were prepared after the standard model,<br />
that have been ground to smaller than 1 mm.<br />
These were scanned before being subjected to<br />
classical analysis. A part of the results obtained by<br />
classical analysis were used for model calibration<br />
and another part for model validation.<br />
RESULTS AND DISCUSSIONS<br />
Total crude fiber content, and the protein<br />
varies between very wide limits, and it mostly<br />
depends on the phase of development which makes<br />
harvesting alfalfa. Cellulosic substances are<br />
organic residue obtained after two consecutive<br />
hydrolysis (one in an acidic environment, the other<br />
246<br />
in alkaline medium) [Dale, 2011]. Content in cell<br />
walls (NDF), crude fiber and hemicellulose that is<br />
intensified with increasing vegetation, ie with<br />
increasing age [Jarrige et al, 1988]. Holland et al,<br />
2008, believe that to obtain a high quality harvest,<br />
alfalfa should be harvested in development stage in<br />
which the leaves are present in greatest amount<br />
before to develop strains, cell walls deposits. The<br />
analysis regarding ADF content was originally<br />
intended as a preparatory step to determine lignin<br />
and cellulose determination [Van Soest, 1994].<br />
Weak acid reagent dissolve hemicellulose, leaving<br />
most of the cellulose. Determination of NDF and<br />
ADF content is often used in order to estimate the<br />
hemicellulose. Holland et al, (2008) states that<br />
leaves suffer small changes during the growing<br />
process of alfalfa and that cellulose and lignin<br />
content, ie content of ADF, and the stem is<br />
increased significantly. Several methods have been<br />
used to isolate or to oxidize lignin in ADF,<br />
prompting acid detergent lignin (ADL).<br />
Digestibility of NDF content and ADF content are<br />
highly variable mostly due to the composition of<br />
lignin [De Boever et al, 1999]. Pecetti et al, (2001)<br />
states that there is a close connection between<br />
cellulose content and lignin content.<br />
Table 1 presents the calibration picture, the<br />
calibration curve for crude fiber, NDF, ADF and<br />
ADL made for alfalfa, the number of samples used<br />
in calibration (N), average value of raw pulp,<br />
minimum and maximum amount which has been<br />
taken for making the model of calibration<br />
calculation, standard error (SD), standard error of<br />
calibration (SEC), coefficient of multiple<br />
determination (R 2 ), standard error of cross<br />
validation (SECV), standardized error of prediction<br />
(SEP) and coefficient of determination (1-VR).<br />
The calibration curve for cellulose has a standard<br />
error for cross validation of 1.35, a low coefficient<br />
of multiple determinations for calibration (0.92)<br />
and a report SECV/SD of 0.28. The calibration<br />
results are similar to those of other authors for the<br />
same type of biological material: thus crossvalidation<br />
standard error obtained Iantcheva et al,<br />
(1999) is 3.12, and the regression coefficient<br />
obtained is similar to that of Brogna, et al, (2009)<br />
ie 0.87. NDF calibration curve has a large standard<br />
error for cross validation (1.70), a low coefficient<br />

0.59, and the regression coefficient obtained is<br />
0.89. Total crude fiber content, and the protein<br />
varies between very wide limits, mostly<br />
dependsing on the phase of development which<br />

makes harvesting alfalfa. The NIRS analysis of the<br />
crude fiber content of alfalfa obtained higher<br />
values on phenophase - seed formation between<br />
18.33% and 46.06%, phenophase - flowering<br />
between 17.56% and 38.47%, harvest 9.53% and<br />
35.06%, but lower the phenophase - average size<br />
30 cm plants which are between 15.96% and<br />
33.61%. NDF content has, in samples of alfalfa,<br />
small values on phenophase - average size 30 cm<br />
plant between 41.84% and 50.29%, the<br />
phenophase - germ values between 44.33% and<br />
54.08% , the phenophase - flowering between<br />
45.20% and 56.97%, and the phenophase - seed<br />
formation between 52.25% and 70.31%. ADF<br />
content consists of cellulose and lignin content, so<br />
alfalfa has higher values in phenophase - seed<br />
formation between 39.25% and 51.65%, the<br />
phenophase - flowering between 32.13% and<br />
42.05%, the phenophase - germ, between 32.96 %<br />
and 39.33%, and the phenophase - medium size<br />
plant 30 cm between 31.14% and 37.54%. ADL, or<br />
lignin content in alfalfa is higher in phenophase -<br />
seed formation between 9.15% and 15.15%, the<br />
phenophase - flowering between 7.28% and<br />
10.49%, the phenophase – germ between 7.53%<br />
and 10.33%. The phenophase - size average<br />
plant 30 cm between 7.02% and 10.04%. Good<br />
results (successful results) were reached in order to<br />
calibrate NIRS device (SEP = 1.058 [CF], 0.964<br />
[NDF], 1.041 [ADF] and respectivelly 1.209<br />
[ADL]). This system offer us the posibibily to use<br />
NIRS technique in determination of organic<br />
substances not only from alfalfa forage but also in<br />
other determination regarding forage quality.<br />
Results regarding alfalfa’s quality in different<br />
vegetation phenophasses were reached by NIRS<br />
technique and there are distinguished on the<br />
scheme and the new system used by the classical<br />
method. As it can be observed the results we obtain

Abstract<br />
Integration is a modern form of agricultural production organization, which can provide a positive economic effect.<br />
By agrifood integrating can be established simple and efficient functional connections between production,<br />
capitalization and consumption, leading to the development of integrated chains (partially or totally) on products or<br />
product groups.<br />
Vertical integration aims to manage one or more products, from raw material to finished product, through specialized<br />
channels, controlled by a decision center.<br />
The authors have proposed based on a case study to highlight the effects of integration on economic efficiency of<br />
agricultural units.<br />
Key words: agrifood integration, economic efficiency, agrifood product<br />
Integration is the activity of regulation<br />
and coordination of interdependent processes,<br />
involving several integrated units under the same<br />
integrator pole (Avarvarei I., Macovei Gh., 1987;<br />
Bidilean V., Bidilean O., 1998, Chiran A., Gîndu<br />
Elena, 2007; Fruja I., Csosz I., Creț N., 1994).<br />
Integration is a modern form of organizing<br />
production and distribution of food products,<br />
which are creating coordination, on a contractual<br />
basis or under one center of decision making, of<br />
different activities.<br />
Agrifood integration may take place at both<br />
macroeconomic and microeconomic level, and<br />
aims the same type of activities (production,<br />
processing, recovery) between units located on the<br />
same rung of the economic chain (horizontal<br />
integration) and between units upstream or<br />
downstream of agricultural production (vertical<br />
integration) (Cojocaru C., 1998; David. N.,<br />
Istudor N., 2000; Petrache A., 2003; Popescu D.<br />
Maria, 1998).<br />
In practice we can find different<br />
organizational forms of integration, which appear<br />
as a necessity of diversification of agricultural<br />
units and effective cooperation with agricultural<br />
companies and individual producers. In this<br />
context, revitalizing agriculture, requires the<br />

MATERIAL AND METHOD<br />
The case study has been conducted at S.A.<br />
AGROIND Berezeni, Vaslui County and aimed at<br />
highlighting the integration role played in the<br />
development and effectiveness of the unit.<br />
The authors used a system of indicators that<br />
were related to technical equipment, total income,<br />
equity, gross profit, investments, bank loans and<br />
subsidies.<br />
The analysis covered the last 10 years, with<br />
the reference years: 2002, 2005 and 2011.<br />
RESULTS AND DISCUSSIONS<br />

Integrating agricultural production is a<br />
higher level of intensive development of<br />
agriculture, a new stage of the process of vertical<br />
cooperation. General characteristic of this process<br />
is increased specialization of production,<br />
separation from agriculture activities and their<br />
takeover by the upstream and downstream sectors<br />
of agriculture. Separating these activities will bring<br />
them together in a unique complex of branches,<br />
which run as one, linked together in terms of<br />
technology.<br />
Concrete implementation of the integration<br />
process is achieved by measures of organization,<br />
planning and management (fig. 1).<br />
It requires a new approach to major<br />
problems of agriculture, which requires the<br />
establishment of firm sizes allowing the practice of<br />
sustainable agriculture, able to apply advanced<br />
technologies and lead to profitability and<br />
efficiency, to strengthen them economical and<br />
organizational.<br />
Integrating agriculture is considered as part<br />
of the mechanism of economic development,<br />
including locally. Therefore, the transition from<br />
traditional agriculture (extensive), in a sustainable<br />
and efficient agriculture, priority approach requires<br />
integration of agricultural and food units in a<br />
complex economic system.<br />
Integration in agriculture acts as a major<br />
process that provides ample opportunities to<br />
introduce scientific and technical progress for the<br />
modernization and production development for<br />
profitable units and raising the living standard.<br />

Agricultural products recovery involves<br />
several steps such as: reception, conditioning,<br />
shipping or storage for different time periods (if<br />
applicable). Grain delivery can be achieved either<br />
directly by the producers (free market) or through<br />
intermediaries, domestic or foreign.<br />
In the horticultural products recovery, the<br />
flow begins with the collection, which includes a<br />
variety of operations that depend on maintaining<br />
product quality.<br />
Recovery of animals for meat is provided<br />
by the farmers on a free market (live or fresh) or<br />
through intermediaries, who buy live animals from<br />
producers, which directs them either to their own<br />
slaughter or other beneficiaries (fig. 2 ).<br />

directly on the open market (fresh milk or dairy<br />
products) or indirectly, by points or organized milk<br />
collection centers in the localities, either directly<br />
from milk processing units (fig. 3) .<br />
In farms specialized in raising dairy cows,<br />
milk is delivered in the "franco farm" system, the<br />
collection and transport is provided by the<br />
processing plants.<br />
In the distribution circuit of agricultural and<br />

CONCLUSIONS<br />
Free market<br />
1. S.A. AGROIND Berezeni, Vaslui County<br />
is an agricultural unit, with a complex<br />
structure, oriented to a semiintegrat<br />
production.<br />
2. The transition from traditional production<br />
system, in which the unit was providing<br />
agricultural inputs, to a European modern<br />
system, in which the production,<br />
processing, distribution and recovery is<br />
made by S.A. AGROIND Berezeni, could<br />
be achieved through modern<br />
management, advanced, which targeted a<br />
new approach to organization and<br />
management system of production, the<br />
attraction of European funds and their<br />
orientation towards development and<br />
strengthening of unit was essential.<br />
3. Conducting the investment was made in<br />
stages and resulting in building two mills<br />
of wheat and corn processing, purchase of<br />
agricultural machinery and livestock, the<br />
modernization of two mills for processing<br />
wheat and maize, 5 stables for dairy cows,<br />
arranging a computerized milking room -<br />

4. The integration process of agricultural<br />
production had a positive effect on<br />
strengthening and streamlining the unit,<br />
so that, in 2011, the total profit (gross and<br />
net) was over four times higher than in<br />
2002, and the efficiency and cost<br />
materialized in a profit growth rate of 7.4<br />
times<br />
5. In the future, the unit must continue the<br />
integration process by modernizing milk<br />
processing plant (currently in storage), the<br />
construction of a plant oil, a fodder<br />
factory, a wine sector, establish a growth<br />
sector and fattening pigs, meat processing<br />
workshop, a district of own stores, etc.<br />

Abstract<br />
Economic efficiency of livestock farms is directly influenced by many factors among which their dimension.<br />
Ensuring economic efficiency of farms is a major objective in developing strategies in agriculture, in which livestock is<br />
an essential factor.<br />
From these aspects the authors have proposed to highlight the role of livestock in strengthening and improving<br />
agricultural units, based on a case study conducted at Agricultural Society „AGROIND” Berezeni, Vaslui County.<br />
Key words: economic efficiency, strategies, livestock units<br />
Agricultural production structure is found<br />
at all levels of economy: macroeconomic<br />
mezoeconomic and microeconomic.<br />
Whatever level is approached, the concept<br />
of production structure refers to production<br />
sectors, the links between them, and the<br />
proportions are developed [Timariu Gh., 2001,<br />
Valorosi F., 2002 ].<br />
Production structure is a system that may<br />
include the following activities: culture structure,<br />
livestock structure, technological structure,<br />
ownership, land structure, the dimensional<br />
structure of agricultural holdings, consumption<br />
structure, down to the structure of varieties, breeds<br />
and hybrids [Roux P., 1986, Samochiș B. et. al,<br />
1997 ].<br />
Production structure can be regarded as a<br />
combination of multiple choices; the answer to this<br />
combination will be reflected in efficiency.<br />
The variants of production structure that can<br />
develop due to this combination are multiple, due<br />
to actual conditions variability, conditions to be set<br />
off by the structure process [Chiran A., Gîndu<br />
Elena, 2000, Leonte Marie - Jaqueline, Bălănică<br />
S.,1998, Voicu R., Dobre Iuliana, 2003].<br />
Therefore, the structure of production<br />
involves the selection of agricultural activities as a<br />
branch of national economy and the various types<br />
of agricultural units.<br />
It includes a diverse number of branches to<br />
form a structure with different levels of intensity:<br />
plant branches have, except vegetables, extensive<br />

character and animal production is characterized<br />
by an intensive type structure.<br />
We can have an intensive structure, given<br />
by the largest share of animal production in<br />
gross value added or an extensively structure, in<br />
which crop production is predominant,<br />
especially grain production [Crăciun A., 1995,<br />
Chiran A. et. al., 2000, Davidovici I., 1993, Ștefan<br />
Marcela, Tănăsescu Rodica et. al., 1997].<br />
One of the indicators for determine the<br />
proportions of branches in the production structure<br />
is "gross added value", which recorded the<br />
following shares in plant and animal production in<br />
the example of several countries in Western<br />
Europe (tab. 1).<br />
The gaps between Romania and the<br />
agriculture of developed countries are large, they<br />
depend on general level of economic development<br />
and the differences between agricultural structures<br />
(ownership structures, production structures,<br />
structures of economic organization, farm size, the<br />
structure of factors of production used, the<br />
structure of agricultural production services, the<br />
structure of production and especially applied<br />
technologies, marketing structures, financing<br />
structures and agricultural support systems, social<br />
protection systems, etc.) [Bold I., Gheorghe P.,<br />
2001, Zahiu Letiția et. al., 2003].

Thus, the average of the two main<br />
branches of agriculture (crop and livestock), in<br />
the value of agricultural production reveals a<br />
development of agriculture. Not until 1990 the<br />
share of animal production was not at the crop<br />
level, representing only 47% of total agricultural<br />
production, but in 1997 reached 37.1%, due to<br />
drastic reduction of livestock after 1989. Thus, the<br />
published data shows that from 1989 until now, the<br />
number of cattle fell by over 55%, pigs by over<br />
2/3, over 62% sheep and poultry by 70%.<br />
European Commission EEC recommended<br />
since 1950, the size of commercial farms to be<br />
over 60 hectares for field crops, or 30-50 cows,<br />
150-200 fattening cattle, 450-600 pigs, etc.<br />

MATERIAL AND METODS<br />
The case study has been conducted at S.A.<br />
AGROIND Berezeni, Vaslui County and aimed to<br />
highlight role of changing the structure of livestock<br />
production and increase economic efficiency. The<br />
study period was 20 years (1992-2011), with<br />
reference points in 1992, 2002 and 2011.<br />
RESULTS AND DISCUSSION<br />
Livestock at S.A. AGROIND Berezeni,<br />
Vaslui County, except pigs and horses, had an<br />
increasing evolution (tab. 2). Thus, compared with<br />
1992, in 2011, the numbers of cattle growth<br />
registered an increase of 100 head (+ 41.7%), the<br />
dairy cows reached 172 head (72.0%) and young<br />
cattle increased by 20.0%, etc. The unit gave up at<br />
breeding and fattening pigs and horses.<br />

In the 20 years of existence, in livestock<br />
farming, the unit was profiled on growth dairy<br />
cows (in closed circuit) and sheep so that we assist<br />
in obtaining additional revenue from the sale of<br />
animal products: cow milk, sheep milk, wool, beef<br />
in live, sheep meat in live (tab. 3).<br />
The total production realized and incomes<br />
were higher than 1992. The highest increases were<br />
recorded in live beef (+ 500.6%), sheep in live (+<br />
45.8%) and cow milk (+ 34.8%).<br />
Total income increased very significantly to<br />
6.5 times higher than in 1992, with obvious<br />
differences in product categories: 21.3 times<br />
(maximum) - in live beef and 257.9% (minimum) -<br />
from sheep milk.<br />
In terms of economic efficiency in the<br />
analyzed period, animal products obtained in S. A.<br />
AGROIND Berezeni was profitable, with<br />
differences in products and in time (tab. 4).<br />
In the structure of gross profit derived from<br />
livestock, in 1992, the largest share (76.8%) held<br />
the milk cow, followed by wool and sheep's milk,<br />
while meat production in live (cattle and sheep)<br />
had a reduced contribution (7.1%.), which shows<br />
that the unit had a production structure that held a<br />
majority share of crop production.

The evolution demonstrates that the unit was<br />
concerned for livestock development, acting<br />
mainly on performance, with a tendency to align to<br />
countries with developed animal husbandry, in<br />
which livestock are an important part of<br />
agricultural production.<br />
Currently, even if there was a clear increase<br />
in revenues from livestock, the share of<br />
agricultural production structure is still low due to<br />
the fact that the unit recovered animal products as<br />
raw material without investing for the milk (milk<br />
processing unit is in conservation – due to<br />
unfulfilled rules imposed by European standards)<br />
or meat. In the future, etc. S.A. AGROIND<br />
Berezeni, Vaslui County should be concerned for<br />
development of livestock, including pigs growth<br />
and to direct investment in processing units and<br />
recovery of finite products of animal origin.<br />
CONCLUSIONS<br />
S.A. AGROIND Berezeni is one of the key units of<br />
Vaslui County, with an activity beyond 20 years of<br />
existence.<br />
Livestock had an increasing trend, except for pigs<br />
and horses, which the unit gave up to.<br />
Total production (milk, meat, wool) and recorded<br />
incomes were growing, the biggest increases<br />
realizing in cow's milk.<br />
Significant are also the total revenue from the sale<br />
of products, provided that the unit has yet to invest<br />
for the design of processing units for milk and<br />
meat, for the recovery of finite products of animal<br />
origin, incorporating high added value.<br />
In terms of economic efficiency, even when the<br />
unit capitalize the production as raw material<br />
(milk, meat, wool), it was found an appropriate<br />
level of gross profit, with a rate of return, which in<br />
some years reached nearly 30%.<br />

DECISION SUPPORT SYSTEM FOR REPLACING OLD MACHINERIES IN<br />
CEREAL FARMS<br />

Farmers take daily decisions with direct impact on farm performance and also on the environment.<br />
Negative environmental consequences are visible in the long term, imposing measures to prevent pollution, and in the<br />
same time, do not affect the economic viability of the farm. The project aims to develop a computerized decision<br />
support system, to assist farmers, in taking decisions regarding replacing old machineries with new ones, in cereal<br />
farms. The research methodology involved: intelligence phase (data collection, problem identification), design phase<br />
(formulate a model, set criteria for choice, search for alternative, predict and measure outcome) and choice phase<br />
(solution to the model, selection of best alternatives, and plan for implementation). The decision support system can<br />
further be used to simulate different scenarios as well as to estimate the economic and environmental impacts.<br />
Key words: efficiency, agriculture, pollution, environment<br />
Agriculture fulfills a variety of functions,<br />
such as: it contributes to the supply of citizens<br />
with safe and quality food, maintain cultural<br />
landscapes through sustainable land management<br />
and help rural areas to remain attractive and viable<br />
(Situation and prospects for EU agriculture and<br />
rural areas, 2010).<br />
Agriculture is an important employment<br />
generator in rural areas where unemployment is<br />
generally higher than in urban areas and generates<br />
jobs in a wide range of farm-related upstream<br />
businesses (veterinarians, equipment dealers,<br />
mechanics, feed and crop supply businesses, etc.)<br />
and downstream businesses (food processors,<br />
transportation, retailers, etc). Also, farms provide<br />
trainings in a wide range of skills such as practical<br />
problem-solving skills applicable in many spheres<br />
of daily life (Scott Jennifer et al., 2008).<br />
Developing decision support systems in<br />
agriculture is not easy and requires different skills<br />
(agriculture, economics, computer science, etc.),<br />
so that the system developed to be efficient and<br />
easy to use by farmers. In the 1960s, researchers<br />
began to study the use of computerized<br />
quantitative models to assist in decision making<br />
and planning. In the 1970s, both practice and<br />
theory issues related to decision support system<br />
were discussed at academic conferences.<br />
Beginning in 1980s many activities associated<br />
with building and studying the decision support<br />
system occurred in universities and organizations<br />
1 Unversitatea de Stiinte Agricole si Medicina Veterinara Iasi<br />
that resulted in expanding the scope of decision<br />
support system applications. Decision support<br />
system practice, research and technology continue<br />
to evolve. By 1996, it had been identified five<br />
specialized types of decision support systems,<br />
including text-oriented, database-oriented,<br />
spreadsheet-oriented, solver-oriented, and ruleoriented<br />
(Power, 2007).<br />
Simulation models estimate what will<br />
happen in the future under different scenarios.<br />
The tool involves the manipulation of large<br />
amounts of data. A decision support system can<br />
help convert data from models into knowledge<br />
that describes the likely results of alternative<br />
courses of action, and apply that knowledge in a<br />
framework that helps decision-makers (Heilman<br />
et al. 2005). To design a decision support system,<br />
one has to determine who the decision-makers<br />
are, what decisions are to be made, and what<br />
information is needed to make those decisions.<br />
Advances in information technology are<br />
creating the potential to create much greater net<br />
benefits from agricultural research. The decision<br />
support system allows farmers to ask "what if"<br />
questions and simulates results. In the twenty-first<br />
century, agricultural professional using<br />
information technologies play an increasingly<br />
important role in crop production and natural<br />
resource management. Increasingly, agricultural<br />
decision support systems are used by producers,
Universitatea de Ştiinţe Agricole şi Medicină Veterinară Iaşi<br />
agricultural consultants, or agribusiness (Ascough<br />
et al. 2002).<br />
A new approach is used different from the<br />
classic one in which only the economic profit<br />
prevails as a basic indicator. The new approach is<br />
to relate investments with the sustainable ecodevelopment<br />
concept and the new economy based<br />
on information society concept (Banacu, 2004).<br />
In their studies, Subić (2006) and Vasiljević<br />
(2007) explain the importance of efficiency<br />
analysis of investments in agriculture. The main<br />
indicators are: Cash flow Return on Investment,<br />
Discounted payback, Internal Rate of Return, Net<br />
Present Value, etc. (Subic et al. 2010). The<br />
investment project model must be automatized in<br />
order to reduce errors (Mackevičius, 2011).<br />
The aim of the current researches is to<br />
develop a computerized decision support system,<br />
to asist farmers, in taking decisions regarding<br />
replacing old machineries with new ones, in<br />
cereal farms.<br />
The results of the research will answer to<br />
a few questions:<br />
What is the need of founding and loan<br />
repayment schedule for a new<br />
investment?<br />
What is the economic efficiency of a new<br />
investment?<br />
What is the energy efficiency of a new<br />
investment?<br />
What is the best investment decision<br />
regarding agricultural machineries in a<br />
specific cereal farm?<br />
How can the agricultural sector work<br />
smarter by considering more options?<br />
MATERIAL AND METHOD<br />
A decision support system provides a tool<br />
to evaluate the complex systems, perform ―whatif‖<br />
scenario analyses, and aid in choosing an<br />
appropriate solution.<br />
Tjia (2009) relates modelling to creative<br />
abilities and art, because it is developed to<br />
automate the process and doesn’t represent a<br />
strictly defined research method.<br />
The decision process, used for this<br />
research, was divided into three phases (Singh et<br />
al. 2008):<br />
Intelligence phase: search and scanning<br />
procedure, data collection, problem identification,<br />
problem ownership, problem classification,<br />
problem statement;<br />
Design phase: formulate a model, set<br />
criteria for choice, search for alternative, predict<br />
and measure outcome;<br />
Choice phase: solution to the model, selection of<br />
best alternatives, plan for implementation.<br />
262<br />
The indicators used to calculate the<br />
economic efficiency of a new investment were:<br />
Total investment without VAT, Annual increase of<br />
turnover, Turnover, Annual increase of production<br />
costs, Production costs, Loan costs, Total costs,<br />
Cash flow of the period, Cash flow at the end of<br />
the period, Return on Investment (ROI), Discount<br />
rate, Discounted payback, Return on invested<br />
capital, Coverage rates by cash flow,<br />
Indebtedness rate, Internal Rate of Return (IRR)<br />
and Net Present Value. The indicators used to<br />
calculate the energy efficiency of a new<br />
investment were: Total Gas/Diesel oil<br />
consumption, CO2 emissions, CH4 emissions,<br />
N2O emissions.<br />
RESULTS AND DISCUSSIONS<br />
The created tool (Excel spreadsheet) has the<br />
following modules: Interface, Old machineries,<br />
New machineries, Founding, Economic efficiency<br />
and Energy efficiency (figure 1). Only white cells<br />
must be filled in. The rest of the cells will be<br />
automatic calculated.<br />
In order to validate the model, it was<br />
calculated the economic and energy efficiency of<br />
replacing an old tractor in a cereal farm with a<br />
new one.<br />
The following data were considered for 60<br />
days of plowing: costs with fuel, costs with other<br />
consumables, costs with taxes, insurance, other<br />
costs (personnel, depreciation costs, other costs),<br />
incomes, the purchase price of a new tractor and<br />
the income from selling the old machinery.<br />
Variant 1: Old tractor U650 with plow<br />
Productivity: 4 hectare/day,<br />
Fuel consumption: 25 litre/hectare,<br />
Cost with fuel: 1.4 euro/litre,<br />
Costs with other consumables: 1260 euro,<br />
Costs with taxes, insurance: 50 euro,<br />
Other costs (personnel, depreciation costs,<br />
other costs): 750 euro,<br />
Price for plowing 1 hectare: 100 euro,<br />
Incomes: 24000 euro.<br />
Variant 2: New tractor with plow<br />
Purchase price: 50000 euro,<br />
Productivity: 6 hectare/day,<br />
Fuel consumption: 18 litre/hectare,<br />
Cost with fuel: 1.4 euro/litre,<br />
Costs with other consumables: 1360.8<br />
euro,<br />
Costs with taxes, insurance: 500 euro,<br />
Other costs (personnel, depreciation costs,<br />
other costs): 5750 euro,<br />
Price for plowing 1 hectare: 100 euro,<br />
Incomes: 36000 euro,<br />
Income from selling the old machinery:<br />
3500 euro.
The difference of productivity comes from:<br />
the working speed, front-wheel drive advantage,<br />
less time resting, easy handling and increased<br />
comfort.<br />
The sources of founding are:<br />
self-financing ( income from selling the<br />
old machinery): 3500 euro,<br />
bank loan: 46500 euro (120 months, 9%<br />
interest rate) (figure 2).<br />

Based on those data, it was automatic<br />
calculated the economic efficiency of the new<br />
investment. The main indicators are:<br />
Discounted payback (Should be<br />
maximum 10 Years): 3.86 years,<br />
Internal Rate of Return (IRR) (Should be<br />
greater than the interest rate, in this case<br />
9%): 27,70%,<br />
Net Present Value (Should be positive):<br />
100000 euro (figure 3).<br />

The following data were considered for<br />
calculated the energy efficiency of the new<br />
investment for 100 hectare of plowing: Total<br />
Gas/Diesel oil consumption, CO2 emissions, CH4<br />
emissions, N2O emissions. The emissions<br />
coefficients of 1 tonne of Gas/Diesel oil<br />
consumption are (GHG emissions from stationary<br />
combustion (English) Version 4.0, 2010):<br />
CO2 emissions: 2,676492 tonnes<br />
CH4 emissions: 0,0003612 tonnes<br />
Figure 3 - Economic efficiency of a new investment<br />
Figure 4 - Energy efficiency of a new investment<br />

N2O emissions: 0,000021672 tonnes<br />
The energy efficiency of the new<br />
investment for 100 hectare of plowing is (figure<br />
4):<br />
Total Gas/Diesel oil consumption:<br />
0,70000 tonnes/U.M.<br />
CO2 emissions: 1,87354 tonnes<br />
CH4 emissions: 0,00025 tonnes<br />
N2O emissions: 0,00002 tonnes
CONCLUSSIONS<br />
The obtained results show the importance<br />
of replacing old machineries in cereal farm, not<br />
just because of high economic efficiency but also<br />
of energy efficiency.<br />
The created tool has the following<br />
advantages:<br />
Has high applicability at farm level,<br />
Can be used personalized database and<br />
the user have direct control of the<br />
simulation,<br />
Takes into account the short and long<br />
time horizons in calculating the main<br />
indicators of the investment,<br />
Can improve the personal efficiency and<br />
speed up the process of decision making.<br />
It can be tested one or more variants of<br />
investment.<br />
Can create a competitive advantage over<br />
competition by choosing the best<br />
alternative of investment after conducting<br />
scenario analysis.<br />
The results emerging from the research<br />
confirm the utility of the created tool and show<br />
that the investment is justified, not only<br />
economically but also from pollution point of<br />
view, conserving environment and improving<br />
farmer’s life.<br />
