Introduction<br />
Dryland agriculture is as old as agriculture. Expanding the domain<br />
of dryland agriculture, currently rainfed agriculture accounts to<br />
52 per cent (which is totally rain dependent) of the net sown<br />
area (73.3 M ha), home to two-thirds of livestock and 40% of<br />
human population and contributes 40% of food production and<br />
supports 83% of coarse cereals, 81% of pulses, 70% of oilseeds,<br />
67% of cotton and 40% of rice. In rainfed regions, agriculture is<br />
influenced by both bio-physical and socio-economic factors and<br />
their interactions. Concerted research and development efforts<br />
in dryland agriculture date back to pre-independence period<br />
in India. In this article, an overview of dryland agriculture<br />
research in All India Coordinated Research Project for Dryland<br />
Agriculture (AICRPDA) is presented.<br />
Historical developments in dryland research in<br />
India<br />
Pre-independence period<br />
The First Famine Commission was appointed in 1880 by<br />
Government of India to suggest measures to tackle drought and<br />
also to suggest preventive measures to avoid famine in future.<br />
In 1920, the Royal Commission, India, noted that “the problems<br />
of cultivation of crops in tracts entirely dependent upon rainfall<br />
deserve far closer attention”. In 1923, the first systematic and<br />
scientific approach to the problem of dryland farming was<br />
started by establishing Dryland Research Station at Manjri near<br />
Pune. Subsequently, during 1933-35, the Imperial (now Indian)<br />
Council of Agricultural Research (ICAR) established five Dry<br />
Farming Research Stations at Solapur, Bijapur, Hagari, Raichur<br />
and Rohtak. The research at these stations continued up to 1943,<br />
based on which a dry land farming technology package was<br />
developed in 1944. The method of cultivation was named as<br />
Bombay Dry Farming, Madras Dry Farming and Hyderabad Dry<br />
Farming (Kanitkar, 1944, Kanitkar, 1960; Kanitkar et. al., 1968)<br />
depending on the province. These dryland farming technology<br />
package mainly consisted of: i). constructing contour bunds as<br />
the basic and essential treatment, ii). occasional ploughing of<br />
lands, iii). repeated shallow cultivation of soils to remove weeds<br />
and conserve moisture during the rainy season, particularly<br />
for rabi (post-rainy season) sorghum, v). adding moderate<br />
quantities of farmyard manure to maintain the fertility and<br />
physical conditions of eroded land, vi). wide sowing with low<br />
seed rate, vii). repeated (4 to 5) intercultivations, viii). adopting<br />
crop rotation, wherever possible and ix). fallowing a part of<br />
the farm holding systematically every year to grow crops in<br />
alternate years. These measures increased productivity by 15-<br />
20% only over a base level of 0.2 to 0.4 t/ha and thus did not<br />
become popular (Choudhary, 1972). This was the first step to<br />
scientific crop planning as per land capability in dryland areas.<br />
All India Coordinated Research Project for Dryland<br />
Agriculture (AICRPDA): Genesis<br />
A Central Soil Conservation Board was established in 1953.<br />
During 1954, 8 soil conservation training and demonstration<br />
centres were established by ICAR with focus on soil conservation<br />
techniques with secondary importance to crop production.<br />
During 1963-64, with the introduction of high yielding varieties<br />
of rice, wheat, maize, and pearl millet and other enhanced use of<br />
inputs in irrigated areas, the agricultural scenario changed in the<br />
country. However, there was a wide disparity between irrigated<br />
and dryland areas necessitating completely a new effort to<br />
improve the dryland production systems. Further, the droughts<br />
of mid-sixties catalysed the Government of India to invest on<br />
dryland research significantly.<br />
The Green Revolution in mid-sixties, though a boon to Indian<br />
agriculture, ushered in era of wide disparity between productivity<br />
of irrigated and rainfed agriculture. Alarmed by such a situation,<br />
the Fourth Five Year Plan (1969-74) emphasized the urgent<br />
need for focusing attention on hitherto neglected farmers of<br />
the dryland to participate meaningfully in the agricultural<br />
development process. This socio-economic imbalance led to<br />
a serious rethinking and a comprehensive network research<br />
program was initiated to stabilize the performance of the<br />
then introduced hybrids of coarse cereals in rainfed region<br />
and to moderate the periodic drought related adverse impact<br />
on total agricultural productivity. Further, droughts of midsixties<br />
catalysed the Government to invest on dryland research<br />
significantly. In 1969, the Government of India with strong aim<br />
of eradicating poverty, evinced keen interest in dryland research<br />
and development programs. In 1970 the ICAR launched the All<br />
India Coordinated Research Project for Dry land Agriculture<br />
(AICRPDA) in collaboration with the Canadian International<br />
Development Agency (CIDA) with 23 centres with cocoordinating<br />
cell at Hyderabad. The AICRPDA centres were<br />
identified based on moisture deficit index (MDI). The initial<br />
objectives of the Project were to i). Conserve soil and water<br />
and make the best use of these resources for crop production,<br />
1
ii). Investigate methods of increasing average per farmer yields<br />
by at least 100%, and iii). Devise means of stabilizing dryland<br />
agriculture by evolving contingency plans to meet seasonal<br />
aberrations. Tangible results were to be tested and adopted in<br />
state government pilot projects attached to each research centre.<br />
Milestones (1970-71 to 1987)<br />
● 1971, the 23 centres included 15 main centres and 8 sub<br />
centres. The 15 main centers were Hisar, Jodhpur, Bellary,<br />
Rajkot and Anantapur in MDI -60 to -80%; Solapur,<br />
Akola, Kovilpatti and Hyderabad in MDI - 40 to -60%; and<br />
Bangalore, Varanasi and Indore in MDI -20 to -40% and<br />
remaining 3 centres, Ranchi, Bhubaneswar and Dehradun<br />
were special problem areas. The 8 sub centres were Bijapur,<br />
Udaipur (shifted to Arjia in 1985), Ludhiana, Anand and<br />
Agra in MDI -40 to -60% and Jhansi, Rewa and Samba in<br />
MDI range of -20to -40%.<br />
● An additional special centre was at IARI, New Delhi<br />
(MDI -40 to -60%) which was subsequently merged with<br />
coordinating cell at Hyderabad. This centre was set up<br />
primarily to cater to basic research needs in the fields of<br />
physiology and agrometeorology<br />
● Dehradun center was discontinued in April 1985. Later<br />
on Anand was shifted to Sardarkrishinagar; Ludhiana to<br />
Hoshiarpur and then to Ballowal Saunkhri, and Samba to<br />
Rakh Dhiansar; Vijayapura and Rewa were upgraded as<br />
main centers<br />
● In 1975, the scope of the project was enlarged to focus<br />
on transfer of technology through training of extension<br />
personnel and teachers of KVKs in innovative dryland<br />
technology<br />
● 1976, the Operational Research concept was introduced<br />
for technology assessment, refinement and transfer. 3 ORP<br />
centres at Ranchi, Bangalore and Hoshiarpur were started.<br />
● 1979 - ICAR launched National Agricultural Research<br />
Project (NARP) which strengthened the regional research<br />
capabilities of agricultural universities with location specific<br />
research including dryland agriculture<br />
● In 1984, 3 ORP centres added at Anantapur, Hisar and Arjia,<br />
in 1985, at Solapur and, in 1986 at Indore<br />
● In1985, Faizabad was added as sub centre<br />
● 1985 - Planning Commission in view of the national need<br />
to strengthen dryland agriculture research, the Project<br />
Directorate /Main centre, Hyderabad was upgraded to<br />
Central Research Institute or Dryland Agriculture (CRIDA)<br />
in April, 1985 to undertake basic and strategic research<br />
while adaptive research continued with AICRPDA centres<br />
with coordinating cell at Hyderabad.<br />

Initially AICRPDA’s activities were supported with CIDA<br />
(Canadian International Development Agency) during<br />
1970-1987 through a bilateral collaboration agreement the<br />
Government of India and Canada signed in 1970. In the first<br />
decade of AICRPDA (1971-81) research was on developing<br />
suitable technology required by the farming community for<br />
increasing and stabilizing crop yields in drylands.<br />
Aligning AICRPDA research with national/states<br />
priorities in rainfed agriculture development and<br />
policy<br />
● 1973 - Drought Prone Area Programme (DPAP)<br />
● 1970s – ICAR Crop AICRPs-AICRPDA: Crop improvement<br />
research in developing drought tolerant varieties by various<br />
crop AICRPs<br />
● 1974 - Integrated Dryland Development Project<br />
● 1977 - Desert Development Programme<br />
● 1982 - <strong>Special</strong> Programme on Integrated Watershed<br />
Management<br />
● 1984 – ICAR Model Watershed Progarmme - 30 model<br />
watersheds (500-1000 ha) in 13 states were assigned to<br />
AICRPDA for technological backstopping.<br />
● 1986 - With the success of model watersheds, Government<br />
of India launched National Watershed Development<br />
Programmes in Rainfed Area (NWDPRA) in 15 states<br />
● 1987 - The performance of model watersheds came into<br />
sharp focus during drought period of 1987.<br />
Presently, the Mandate of AICRPDA (since 2018) is:<br />
On-station research<br />
● To optimize the use of natural resources, i.e. rainfall, land and<br />
water, and to minimize soil and water loss and degradation<br />
of environment<br />
● To evolve a simple technologies to increase crop productivity<br />
and viability<br />
● To increase stability of crop production over years by<br />
providing improvements in natural resources management<br />
and crop management systems and alternate crop production<br />
technologies matching weather aberrations<br />
● To develop alternate and sustainable land use systems; and<br />
● To evaluate and study transferability of improved dryland<br />
technologies to farmers’ fields.<br />
On-farm research<br />
● On-farm participatory research on rainfed integrated farming<br />
systems<br />
● Technology assessment/refinement<br />
● Implementation of the research findings/ doable rainfed<br />
technologies
AICRPDA - CIDA collaborative research (1970-71 to 1987)<br />
During 1970-71 to 1987, the AICRPDA-CIDA collaborative<br />
research was in three phases i.e., 1970-75, 1976-82 and 1982-<br />
87. During this period, sound foundations of systematic and<br />
location-specific research were laid out across AICRPDA<br />
centres (IARI, 1970; Krishnamoorthy, 1971; Krishnamoorthy,<br />
1972; Krishnamoorthy and Chowdhury. 1972; Krishnamoorthy<br />
et. al., 1974; Singh, 1987; Singh and Singh, 1987).<br />
First Phase (1970-75): The location specificity of the<br />
technology was emphasized leading to development of specific<br />
projects with the type experiments in agronomy on the concept<br />
of “Low Monetary Input”, the basic crop production practices<br />
like time of seeding and plant population-geometry in relation to<br />
rainfall, and weed management, crop substitution and cropping<br />
systems as a necessary input for improved production. The focus<br />
was on four major aspects related to dryland agriculture viz.<br />
agronomy, soils, plant breeding and agricultural engineering.<br />
The significant feature of this programme was attaching each<br />
dryland research centre to the Integrated Dry Land Agriculture<br />
Development Project (IDLADP), where scientists interacted<br />
with the farmers leading to problem identification.<br />
During early 1970s, the AICRPDA centres were initiated research<br />
on contingency crop planning and midseason correction to cope<br />
with delayed onset of monsoon, early withdrawal monsoon,<br />
intermittent dry spells of various durations, and prolonged<br />
monsoon. During 1971-72, sunflower was introduced as alternate<br />
crop at all centres. Research on rainwater harvesting continued<br />
with focus on farm ponds, storage of water in farm ponds,<br />
protective irrigation and diversification to high value crops.<br />
After 1985, horticultural crops were introduced as alternate land<br />
use systems. Poor crop establishment was the major problem<br />
with most framers using bullock power. Seed drills for bullock<br />
power were developed. Canadian seed drills were imported to<br />
ascertain whether the mechanical principles which they used<br />
could be modified for Indian conditions and adopted for bullock<br />
drawn equipment. At Centres, agricultural engineers worked in<br />
close association with agronomists to develop ferti-seed drills<br />
viz. Shivaji multipurpose tool bar (Soalpur), Malaviya seed drill<br />
(Varanasi), Birsa seed rill (Ranchi), Ridger planter (Hisar) and<br />
later Plough planter by CRIDA.<br />
The emphasis on intercropping research was to identify the<br />
regions where intercropping was feasible and worthwhile to<br />
increase in cropping intensity and secondly, to compare the<br />
productivity and stability of intercropping versus monocropping<br />
in agro-climatic regions where only a single crop is feasible<br />
in a year. The research strategy for each region consisted of<br />
screening of different crops for compatibility in intercropping<br />
systems, modifying planting patterns, such as paired row<br />
planting, identifying optimum row ratios for efficient moisture<br />
and nutrient utilization by component crops, identifying the best<br />
50 Years of Dryland Agriculture Research in AICRPDA: An Overview<br />
3<br />
cultivars for the component crops and determining the optimum<br />
N and P doses for intercropping systems (Freyman, 1975;<br />
Venkatachary et. al., 1979; Patel et. al., 1981; Chetty, 1983;<br />
Singh and Singh, 1983; Singh et. al., 2004). The significant area<br />
identified was tailoring the technology to the aberrant weather<br />
situations.<br />
Second Phase (1976-1982): the focus on dryland research was<br />
identifying efficient methods for crop lifesaving irrigation,<br />
in situ moisture conservation by tillage, continued focus on<br />
identifying efficient crops and cropping systems, crop husbandry<br />
for weather aberrations and alternate or multiple land use.<br />
Third Phase (1982-1987): Dryland research continued cropping<br />
systems, i.e., both intercropping and double cropping, that could<br />
ensure stable optimal yields and maximize profits in relation to<br />
agroclimatic resources, with further refinement of the systems<br />
through identification of genotypes, manipulation of sowing and<br />
harvesting dates and plant populations and fertilizer use. Pulses<br />
and oilseeds formed important components of the cropping<br />
systems research (AICRPDA, 2003). Permanent manurial trials<br />
wer initiated at 18 Centres for efficient carbon and nutrient<br />
balance and optimization (1984 onwards). These benchmark<br />
experiments are serving as platforms for intensive research on<br />
carbon sequestration, nutrient use efficiency, development of<br />
data sets for C modeling and soil quality assessment.<br />
Initial outputs<br />
The dryland research amply demonstrated that yield of<br />
dry land crops could be increased by at least 100% with<br />
improved varieties and sowing methods and higher yields with<br />
advancement of sowing dates, particularly post rainy period<br />
in Deccan region, minimizing the risk with split application<br />
of N, and alternate crops for aberrant weather situations. Dry<br />
seeding is recommended for the locations/soil types where the<br />
conditions (soil) do not permit sowing operations with the onset<br />
of monsoon. Innovated in 1973, in the Alfisols of Hyderabad,<br />
sorghum + pigeonpea intercropping system (2:1) was promising<br />
in replacement series while sorghum (1.8 lakh plants/ha) +<br />
pigeonpea (75,000 plants/ha) and sorghum+ greengram (2:1) in<br />
additive series were promising. Studies on low monetary inputs<br />
like improved seed, timely sowing and timely weeding helped<br />
bridging the yield gaps in sorghum in Alfisols of Hyderabad<br />
(Singh et. al., 1987). Across the AICRPDA centres, probable<br />
and efficient crop growing periods were established based<br />
on rainfall, potential evapotranspiration and water retaining<br />
capacity of soils. Kaolin was identified as the most effective<br />
anti-transpirant for controlling the transpiration losses of barley<br />
and sorghum. Under severe drought at Anantapur, the groundnut<br />
yield increased by 173 kg over 520 kg/ha with 6% kaolin spray<br />
(during the experimental period of 7 seasons, drought occurred<br />
only in 4 seasons). In moderate drought at Dantiwada, pearlmillet
yielded 213 kg more over 894 kg/ha, while the calcium chloride<br />
spray (5%) increased yields by 222 kg over 894 kg/ha (during<br />
the experimental period of 6 seasons, drought occurred only<br />
in one year). In moderate drought, under semi-arid region and<br />
Inceptisols, pearlmillet showed an increase of 75 kg over 1954<br />
kg/ha with kaolin spray. In black soils regions, with 500 to 1000<br />
mm rainfall, the productivity of upland rainy season crops could<br />
be substantially improved by providing furrows graded to 0.2 to<br />
0.3% slope to transmit excess rainwater (Verma, 1982). Another<br />
milestone in dryland research was refinement of cropping<br />
system technology, i.e., in case of rainy season crops, choice<br />
of crops and varieties could be decided by the rainfall pattern<br />
and length of effective growing season, however in post-rainy<br />
season crops grown on conserved soil moisture, the available<br />
soil moisture in the profile at sowing time decided the choice<br />
of crops. With the advent of high yielding and input responsive<br />
varieties to suit different situations, agriculture became more<br />
‘Production oriented’ (Vijayalaxmi et. al. 1975; Friesen et. al.,<br />
1982; Venkateswarlu, 1985; Sigh and Venkateswarlu, 1985;<br />
Singh et. al., 1987; Singh et. al, 1988; Hegde, 1988).<br />
The concepts of off-season tillage and life saving irrigation with<br />
harvested rainwater for better crop production were established.<br />
In chronic drought prone areas, deep tillage (20-30 cm) was<br />
found specifically applicable to soils having textural profiles<br />
or hard pans. Under uni-modal (
either as base crop or intercrop performed better, particularly in<br />
sorghum, cotton and pearl millet based intercropping systems<br />
(AICPRDA, 2003; Rafey and Verma, 1988). In widely spaced<br />
crops like pearl millet and pigeonpea, 2:1 proportion was found<br />
to be better at several locations (Umrani et. al., 1992). Suitable<br />
varieties of predominant rainfed crops for weather aberrations<br />
were identified, for example, for delayed onset of monsoon, the<br />
sorghum varieties recommended were: CSH-1 at Akola; M-35-1<br />
at Bellary; S-1049 at Dantiwada; CSH-6 at Udaipur (AICRPDA,<br />
2003).<br />
Crop substitution concept was evolved in which the performance<br />
of various new crops was evaluated vis-a-vis traditional crops,<br />
for e.g., in Vertisols of Bellary, sorghum was more efficient<br />
than cotton (Singh, 1987). The cropping intensity could be<br />
increased considerably depending on the soil types and moisture<br />
availability period. However, the duration of the crop cultivars<br />
influenced the selection of a cropping system. Hence, the dryland<br />
research in this area clearly brought out that in the high rainfall<br />
(> 1000 mm) regions of Orissa, Eastern Uttar Pradesh and<br />
Madhya Pradesh, a second crop could be grown in the residual<br />
moisture after a 90 days duration variety of upland rice than 120<br />
days duration. Similarly in the Vertisols of Malwa (Madhya<br />
Pradesh) and Vidarbha (Maharashtra), a change of 140 or 150<br />
days sorghums to about 90 or 100 days cultivars provided an<br />
opportunity to grow chickpea or safflower in sequence. Double<br />
cropping was possible only in areas receiving more than 750<br />
mm rainfall with a soil moisture storage capacity of more than<br />
200 mm. Another significant contribution of dryland research<br />
was the identification of the most compatible genotypes of the<br />
component crops of the system for higher system productivity.<br />
A new concept of fertilizer use was evolved to tailor to the<br />
available soil moisture status at least in post rainy season areas.<br />
The studies conducted across AICRPDA centres showed that 1<br />
kg of fertilizer N produced additional grain yield varying from<br />
4.3 to 38 kg in a variety of crops (rice, sorghum, pearlmillet, rabi<br />
sorghum, wheat, safflower and mustard) grown under different<br />
rainfall environments and diverse soil types (Anonymous,<br />
1977). The magnitude of response deceased with the higher<br />
rates, except for maize. Yield advantages were associated with<br />
the split application of N in cereals. Application of inorganic<br />
and organic fertilizers in set furrows in groundnut, pearlmillet<br />
and cotton (Saurashtra) gave better yields.<br />
The sustainability analysis of the practices developed for<br />
increasing productivity of dryland crops is an aspect distinctly<br />
different from productivity. In dryland research, methods of soil<br />
and water conservation have been regarded as a pre-requisite<br />
to providing better crop growing environment. Other practices<br />
like optimum plant density, appropriate cropping system and<br />
fertilizer use have been found to be the key factors in increasing<br />
the productivity of dryland crops. Although these aspects have<br />
50 Years of Dryland Agriculture Research in AICRPDA: An Overview<br />
5<br />
been documented in terms of their relative importance for<br />
increasing productivity, the sustainability aspect did not figure<br />
anywhere. Sustainability is directly linked with the minimum<br />
guarantee that a given practice can hold in terms of productivity<br />
and profitability. In case of plant density, the average productivity<br />
over varying plant densities are positively correlated with<br />
sustainability in most of the situations. Sustainability in yield<br />
due to plant density is interacting with crop, variety, season,<br />
rainfall, soil type and fertilizer.<br />
In most of the situations, the sustainability of yield was higher<br />
when the recommended dose of fertilizer was applied. In<br />
case of cereals, higher sustainability was obtained when the<br />
recommended dose of nutrients was applied through chemical<br />
sources. In the case of oilseeds, however, the recommended dose<br />
applied half through chemical fertilizer and other half through<br />
organic source led to higher sustainability values. Available<br />
nitrogen, organic carbon and phosphorous content in soil were<br />
increased with organic fertilizer application. Application of<br />
crop residues in combination with chemical fertilizer resulted<br />
in higher sustainable yield and maintained higher levels of<br />
nitrogen, phosphorous and organic carbon. Green leaf manuring<br />
proved promising in increasing the sustainability in yield and<br />
improving the organic carbon, infiltration rate and hydraulic<br />
conductivity of the soil (Singh et. al., 1990).<br />
The experiments on alternate land use systems (ALUS) for<br />
arable and marginal lands were initiated at AICRPDA in 1981.<br />
Though the work on alley cropping was in progress since 1981<br />
at AICRPDA, it became a core project of AICRPDA programme<br />
only in 1985 when 10 centres initiated this work. Leucaena<br />
lecocephala based forage alley cropping system was developed<br />
at Hyderabad with the multiple objectives like forage, foragecum-mulch,<br />
and forage-cum-poles. The ALUSs developed were<br />
tree farming, ley farming (Stylosanthes hamata with sorghum<br />
rotation), silivipasture (Leucaena leucocephala + Stylosanthes<br />
hamata + Cenchrus ciliaris) agri-horticulture (guava/custard<br />
apple/pomegranate/ber based) (Korwar et. al., 1997; Singh<br />
et. al., 1987). Leucaena leucocephala is the most popular tree<br />
species to serve as hedgerow in the alley cropping system<br />
(Hegde et. al., 1988). Studies at AICRPDA during 1975-1983,<br />
revealed that Dicanthium, Sehima and Lasiurus are suitable for<br />
severe drought prone areas while Cenchrus ciliaris, Panicum<br />
maximum and Urochloa were for moderate drought prone<br />
areas. Stylosanthus hamata, a pasture legume, was identified for<br />
improvement of soil fertility and as quality fodder for Alfisols of<br />
Hyderabad (Reddy and Hampaiah, 1982)<br />
During 1972-73, large scale scarcity of rainfall was experienced<br />
all over the country, particularly in the scarcity region of<br />
Maharashtra, Karnataka and Andhra Pradesh. Roving seminars<br />
were organized by the ICAR at different locations, at the<br />
end of which new phrases were coined viz., contingent crop
planning, and mid-season correction. As a follow up, dry land<br />
centres collected data on these two aspects and after analysis<br />
of weather data for the past 100 years, listed the weather<br />
aberrations: i) delayed onset of monsoon; ii) early withdrawal<br />
of monsoon; iii) intermittent dry spells of various durations;<br />
iv) prolonged dry spells causing changes in the strategy; and<br />
v) prolonged monsoon. Agronomists at the centres at Solapur,<br />
Bijapur, and Hyderabad worked on these aspects and developed<br />
contingent crop planning strategies for delayed on set monsoon<br />
(AICRPDA, 1983a). The efforts made by the agronomists in this<br />
scarcity region by introduction of safflower as a sole crop in<br />
scarcity zone of Maharashtra ultimately augmented the oilseed<br />
production, further, at Indore safflower was introduced in<br />
rotation with soybean which gave a yield of 2 t/ha with residual<br />
moisture. In Bhubaneswar region, groundnut was introduced as a<br />
rabi crop. Contingency plans, for each region, was a conceptual<br />
approach unique from AICRPDA project in developing location<br />
specific contingent crop strategies which were first published<br />
in 1977 in Indian Farming, and with further refinements and<br />
updating in crops and varieties, the first document was brought<br />
out by AICRPDA in 1983 on “Contingent crop production<br />
strategy in rainfed areas under different weather conditions”<br />
(AICRPDA, 1983b). Another significant outcome of dryland<br />
research in dry land farming was, in 1979, the AICRPDA<br />
was the first to bring out “Improved Agronomic Practices for<br />
Dry land Crops in India” with the recommendations on the<br />
soil type-wise crops and varieties, contingent crop planning,<br />
suitable cropping systems and other agronomic practices. The<br />
concept and contents were well received and emulated by other<br />
AICRPs. The contributions of ORPs in demonstration of dry<br />
land technologies, action research and feedback on technologies<br />
was immense which helped in refining technologies related to<br />
in situ moisture conservation practices, cropping systems, etc.<br />
(Singh et. al., 1987).<br />
Watershed approach for dryland agriculture<br />
development<br />
The soil and water conservation technologies emanated from<br />
the project could contribute to design and implement Integrated<br />
Dryland Agriculture Development (IDLAD) project during<br />
1971-1981 in various states. The project through adoption of 30<br />
model watersheds (1983-87) clearly established that a permanent<br />
solution to the problems of chronically drought affected areas<br />
through overall development of the water and land resources.<br />
Further, productivity gains in these watersheds indicated two<br />
to several fold increase in crop productivity; rise in income<br />
through profits and improvement in cropped area and cropping<br />
intensity and a concomitant rise in number of working days with<br />
overall potential in improving and stabilizing the productivity of<br />
Ravindra Chary et al.<br />
drylands. Above all it stimulated the concept of development of<br />
rainfed agriculture with watershed as the unit of activity. Based<br />
on the experiences of these model watersheds, Government of<br />
India launched National Watershed Development Programmes<br />
in Rainfed Area (NWDPRA) in 1986 in 15 states. Launching<br />
of NWDPRA has its roots in the successes witnessed through<br />
model watershed programme and a vital aspect of this massive<br />
national effort in stabilising and improving the quality of<br />
agriculture in rainfed areas.<br />
Initial experiences gained<br />
Early research efforts in AICRPDA during 1970s and 1980s<br />
helped in identifying potential production through a combination<br />
of simple agronomic techniques such as off-season tillage<br />
and contour farming to enhance in situ water conservation,<br />
improved biotypes of crops, soil fertility management to<br />
overcome nutritional constraints, and weed control to avoid<br />
non-productive use of soil stored moisture and nutrients. The<br />
research also provided feedback for further refinement of<br />
the production agronomy techniques, cropping systems and<br />
rainwater-management methods. By adjusting row ratios of<br />
crops of an intercropping system to minimize competition, the<br />
traditional mixed cropping system was upgraded in productivity.<br />
Compared to earlier efforts, it was clearly recognized that to bring<br />
about stability and improvement in rainfed agriculture, it was<br />
essential to apply the techniques of rainwater conservation and<br />
standard agronomic practices in an integrated mode. With this<br />
approach the productivity of rainfed crops rose by a factor of 2 to<br />
3. More importantly, despite aberrations in year-to-year rainfall<br />
behaviour, occurrence of total crop failure could be eliminated.<br />
Applicability of new research findings was tested in the farmers’<br />
fields with promising results. However, the sustainability of<br />
various farming techniques under farmer’s situation was noncommensurate<br />
with the benefits demonstrated at the research<br />
farm. A major emphasis of the technology application was<br />
aimed at arable farming. As a result, the application ignored the<br />
capability of land to support various farming enterprises and did<br />
not integrate the development of non-arable areas with arable<br />
areas. Nearly one half of the lands in rainfed areas do not qualify<br />
to be devoted to arable farming based upon the land capability<br />
classification criteria. Collection of runoff in farm ponds was<br />
not widely accepted because the cost of seepage proofing, a<br />
necessary investment for high-percolating Alfisols, was not<br />
affordable to a majority of the small and marginal farmers.<br />
Apart from problems of seepage and high initial investment in<br />
constructing individual farm ponds, water lifting and method<br />
of irrigation of limited amounts of harvested water remained<br />
crucial aspects of adoption.<br />
6
Keeping in view the above constraints, the research efforts<br />
were reoriented during the 1980s. It was recognized that<br />
water deficits in a natural body, such as land, is a reflection<br />
of imbalance in the hydrological cycle on a micro-scale. The<br />
effective conservation of rainwater and its management and<br />
budgeting led to the emergence of a watershed concept which<br />
integrates the development of arable and non-arable areas. Since<br />
conduct of rainwater in one area influences its availability in<br />
the adjacent area, with watershed as the basic unit of activity it<br />
became possible to craft comprehensive research approach for<br />
an efficient natural resource use plan. In 1983, ICAR piloted<br />
a National Watershed Programme with 47 model watersheds<br />
spread across the country. AICRPDA was bestowed with<br />
the responsibility of backstopping the activities of 30 model<br />
watersheds in 13 states. Compared to earlier programmes, the<br />
entire strategy framework was holistic in that it combined the<br />
technologies relating to soil and water conservation with the<br />
standard agronomic practices against the backdrop of alternative<br />
land uses. Furthermore, these watersheds served as testing<br />
grounds for the already available technologies. The impact at<br />
Nartora, Tejpura, Mittemari received the National Productivity<br />
Awards for excellence. Significant gains in terms of productivity,<br />
groundwater recharge and cropping intensity could be observed<br />
at several watersheds.<br />
A modest beginning on adoption of improved technologies was<br />
observed as early as in 1970s. This resulted in corresponding<br />
improvement in the productivity of rained crops like sorghum,<br />
pearlmillet, groundnut and cotton are a testimony to this act.<br />
During 1981-93, area under coarse cereals put together (rained<br />
area 91%) had fallen by 17 Mha. Despite this marked fall in area,<br />
the production increased by 6 million tonnes. This indicated a<br />
positive impact of research activities and then interfacing with<br />
development efforts.<br />
The soil and water conservation technologies emanated from<br />
the project could contribute to design and implement Integrated<br />
Dryland Agriculture Development (IDLAD) project during<br />
1971-1981 in various states. The project through adoption of 30<br />
model watersheds (1983-87) clearly established that a permanent<br />
solution to the problems of chronically drought affected areas<br />
through overall development of the water and land resources.<br />
Further, with productivity gains in these watersheds indicated<br />
two to several fold increase in crop productivity; rise in income<br />
through profits and improvement in cropped area and cropping<br />
intensity and a concomitant rise in number of working days with<br />
overall potential in improving and stabilizing the productivity<br />
of drylands. Above all it stimulated the concept of development<br />
of rainfed agriculture with watershed as the unit of activity.<br />
Launching of NWDPRA has its roots in the successes witnessed<br />
through model watershed programme and a vital aspect of this<br />
massive national effort in stabilising and improving the quality<br />
of agriculture in rainfed areas.<br />

Innovations in prioritization of research in<br />
AICRPDA<br />
A unique and innovative approach for research prioritization<br />
and technical programme development was initiated since<br />
2001 in AICRPDA by conducting: i) Brainstorming sessions,<br />
ii). Production systems-wise National Group Meetings and iii).<br />
Stakeholder Consultation Workshops, in 2001, 2008 and 2013,<br />
respectively. During these meetings/workshops the participants<br />
were farmers, scientists from CRIDA, SAUs, AICRPs, ICAR<br />
Institutes and KVKs, officials from ATMA, state line departments<br />
and NGOs. These meetings/workshops were conducted for<br />
stocktaking of the status and aspirations of the stakeholders<br />
under different land classes with farmers, link departments,<br />
research organizations, non-governmental organizations and<br />
other participants in the system at all Centers for the first time in<br />
the history of Project. The above meetings were conducted after<br />
a series of brainstorming meetings conducted by the individual<br />
centers with the stakeholders at their respective locations to<br />
draw the perspective plan of the centre. During stakeholder<br />
consultation workshops were held on emerging problems in<br />
dryland agriculture to integrate into technical programme of the<br />
centre and convergence mechanisms for technology upscaling.<br />
The Strengths, Weaknesses, Opportunities and Threats<br />
(SWOTs) are derived. The current status on rainfed agriculture<br />
viz. crops, natural resources etc., were analysed. Then the<br />
ongoing Technical Program was examined along with the<br />
scientists of the centre to analyse the gaps. New programs are<br />
formulated or treatments in the present program are augmented<br />
to fulfil expected needs within the natural resource environs for<br />
implementation. The research collaboration at centres so far has<br />
been with CRIDA, AICRPAM and other AICRPs in NRM, Crop<br />
sciences, Horticulture and Agriculture Engineering Divisions of<br />
ICAR for implementing the core research programmes either<br />
Institute or externally funded national/international/ state funded<br />
projects, some also include consultancy projects. These projects<br />
supported in meeting the objectives of AICRPDA, particularly in<br />
thrust areas of rainwater management, evaluation of germplasm,<br />
nutrient management, soil quality, carbon sequestration,<br />
conservation agriculture, climate resilient agriculture, and also<br />
for technology assessment, refinement and upscaling.<br />

● Characterized rainwater harvesting of potential zones in the<br />
agroclimatic domains of AICRPDA centres<br />
● Developed rainfall intensity, duration and frequency (IDF)<br />
curves for specific rainfed agroecoliogies<br />
●●<br />
Identified emerging nutrient deficiencies in rainfed<br />
production systems: Soils of 19 out of 21 centres had low in<br />
organic carbon (< 0.5%); available N was low in most of the<br />
soils except surface soils of Indore and Ranchi; low to very<br />
high P, available K and S varied from low to high; available<br />
Zn was below critical limit; deficient in available Ca (< 1.5<br />
me/100 g), Mg deficient (0.67, moderately<br />
sustainable (0.33-0.67) and low sustainable ( 1500 mm) and soil types (Entisols,<br />
Inceptisols, Vertisols, Alfisols, Aridisols) viz. deep tillage,<br />
compartmental bunding, inter-plot rainwater harvesting<br />
techniques, conservation furrow, broad bed & furrows,<br />
raised bed & furrow system, ridges & furrows, tied ridges,<br />
zing terracing, mulching techniques etc. (Katama Reddy et.<br />
al.,1992; Yellamanda Reddy,1994; Guled et. al., 2003).<br />
●●<br />
Ex-situ rainwater management: At centres, based on<br />
catchment-storage-command area relationship, standardized<br />
rainwater harvesting structures viz. farm pond and other<br />
water harvesting structures for diverse rainfall and soil<br />
types and efficient rainwater utilization for higher water<br />
productivity (Shirahatti et. al., 2019; Balyan et. al., <strong>2022</strong>;<br />
Water resource thus developed could be used for life<br />
saving irrigation, extension of cropping season, increasing
cropping intensity and raising of high-value cash crops.<br />
The advantages of supplemental irrigation from harvested<br />
rainwater were significant and considerable improvement<br />
in crop yields (25-45%) was recorded at AICRPDA centres.<br />
Efforts were made for Packaging farm pond technology with<br />
standard farm pond sizes, lining with single and combination<br />
of environmentally friendly low cost materials, to reduce<br />
seepage losses, water lifting with energy efficient lifting<br />
pumps, reducing evaporation losses, and efficient water<br />
utilization through micro-irrigation systems<br />
● Developed location-specific open well and bore well recharge<br />
models at Parbhani, Vijayapura, Bangalore, Jagdalpur and<br />
Rajkot centres with efficient filtering mechanisms<br />
Cropping systems<br />
The research on crops and cropping systems was focused<br />
on evaluation of the most efficient crops and their varieties<br />
for each agroclimatic location. Systematic designs were<br />
developed and improved to suit dry land conditions for<br />
evaluation of intercropping. Standard agronomic practices<br />
were worked out for important food crops. Most efficient<br />
crop varieties have been identified based on a continuous<br />
evaluation and screening both at research station followed<br />
by farmers’ fields.<br />
With the base crop of 100 days duration, for intercropping,<br />
varieties of 140-150 days duration on deep moisture -<br />
retentive soils and 60-70 days duration on medium deep<br />
soil were highly successful. A pool of germplasm of short<br />
duration underexploited crops such as horsegram has been<br />
screened and promising lines identified for increasing<br />
cropping intensity by sequence/ intercrop. In case of<br />
plant density, the average productivity over varying plant<br />
densities is positively correlated with sustainability in most<br />
of the situations. Sustainability in yield due to plant density<br />
is interacting with crop, variety, season, rainfall, soil type<br />
and fertilizer. When fertilizer was applied the sustainability<br />
index started decreasing at a lower plant density compared<br />
to the situation where fertilizer was applied at a higher plant<br />
density (Ravindra Chary et. al., 2012).<br />
● Developed efficient and risk resilient and productive<br />
intercropping/strip cropping systems for diverse rainfed<br />
agro-ecologies i.e. rainfall ( 1500 mm) and soil<br />
types (Entisols, Inceptisols, Vertisols, Alfisols, Aridisols). In<br />
the late 1980s and 1990s, intercropping of vegetables (okra,<br />
radish, chillies etc.) with grain crops (pigeonpea etc.) for<br />
higher income was pursued vigorously in some AICRPDA<br />
centres (Phulbani, Varanasi etc.) (AICRPDA,2003; Shankar<br />
et. al., 2001; Surakod et. al., 2016). Further, the additive<br />
series in intercropping systems was found to be most<br />
successful with base crops as sorghum, maize, pearlmillet,<br />
pigeonpea, safflower and wheat, with higher LERs (with<br />
Ravindra Chary et al.<br />
12<br />
●●<br />
average of 23% more) than replacement series with multiple<br />
benefits of higher output and returns, spread labour peaks,<br />
maintenance of soil fertility (with inclusion of legume) and<br />
stability in production. In ICSs, the complementarity could<br />
be increased with the staggered planting of component crops<br />
than simultaneous planting. Pigeonpea had been found<br />
to be unique and highly preferred component crop across<br />
production systems (AICRPDA, 2003; Itnal et. al.,1994).<br />
Sorghum+pigeonpea was the most preferred ICS followed<br />
by upland rice/groundnut/sorghum+pigeonpea. Overall, the<br />
best base crops appeared to be upland rice, sorghum and<br />
pigeonpea, while pigeonpea, greengram and soybean were<br />
the best component crops.<br />
Developed double cropping systems for high rainfall<br />
zones: With sufficient rainfall (usually > 800 mm) double<br />
cropping was possible and out of the two crops, one could<br />
be short duration (60-70 days, usually legume), and another<br />
could be long duration of 110-120 days (usually cereal). At<br />
Varanasi, Phulbani, Rewa and Ranchi, sequential cropping<br />
was very much possible while with more success in selection<br />
of suitable crops and their sequence. Short duration (60-<br />
70 days) legumes such as greengram/blackgram or early<br />
cowpea followed by 100-120 days cereal crop was an ideal<br />
sequential cropping system while one cereal in the sequence<br />
was useful to meet grain and fodder requirements. In<br />
regions where rainfall was more than 1000 mm (Rewa and<br />
Ranchi), upland rice-chickpea/lentil was a proven sequence.<br />
Successful intercropping was when the optimum plant<br />
population of base crop through the row arrangements while<br />
maintaining the plant density of companion crop/intercrop<br />
near optimal (range could be 75 -100%). In high rainfall<br />
(> 1000 mm) regions of Odisha, Eastern Uttar Pradesh<br />
and Madhya Pradesh, a second crop could be grown in the<br />
residual moisture after a 90-day duration variety of upland<br />
rice than 120 days duration, similarly in the Vertisols of<br />
Malwa (Madhya Pradesh) and Vidarbha (Maharashtra), a<br />
change of 140 or 150 days sorghum to about 90- or 100-<br />
days cultivars provided an opportunity to grow chickpea or<br />
safflower in sequence. Double cropping was possible only<br />
in areas receiving more than 750 mm rainfall with a soil<br />
moisture storage capacity of more than 200 mm<br />
● Developed strip cropping systems amenable to mechanization<br />
viz. maize (grain) with 2/3 area + maize (fodder) with 1/3 area<br />
(Semiarid Vertisols, Arjia); maize (6 m strip) +blackgram<br />
(2.4 m strip) (subhumid Inceptisols, Ballowal Saunkhri);<br />
soybean + pigeonpea cropping with strips of 18.9 m each<br />
(18 & 12 rows/strip) (semiarid Vertisols, Parbhani).<br />
Crop diversification<br />
Based on the research information for the past 40 years across<br />
AICRPDA, a new approach was identified for horizontal and
vertical diversifications potentials of rainfed cropping systems<br />
in typical rainfed districts in India, which were given for five<br />
major crop based production systems viz. rice, oilseeds, pulses,<br />
cotton and coarse cereals under the Simpson crop diversification<br />
indices of 80-100%, 60-80%, 40-60% and less than 40%, as well<br />
as under different soil degradation status (Vittal and Ravindra<br />
Chary, 2007). Diversification with nutri-cereals in rainfed<br />
agroecologies : at Kovilpatti, in post-monsoon semiarid Alfisols,<br />
intercropping of medium duration pigeonpea (Co(Rg)7) with<br />
nutricereals in 2: 6 ratio, i.e. barnyard millet (CO 2)/ foxtail<br />
millet (CO 7)/ kodo millet (Paiyur 1)/ proso millet (CO 5)/<br />
little millet (CO 5) and pearlmillet (CO 10); in bimodal rainfall<br />
zone, at Darsi, foxtail millet- cowpea/blackgram; pearlmilletgreengram/cowpea/backgram<br />
and pigeonpea+-foxtail millet<br />
(1:5)/pearlmillet (1:2), foxtail millet-greengram; at Phulbani,<br />
finger millet (5 rows) in sunken bed + okra (2 rows).<br />
Contingency crop planning<br />
The rainfall data at 23 AICRPDA locations in the country were<br />
analysed with regards to: a) the dates of onset and termination<br />
of the rainy season and its variability, and b) the distribution of<br />
rainfall within the rainy season. The information so generated<br />
was fitted the selection of efficient crops, varieties, and<br />
cropping systems. Later, the agro-climatological studies helped<br />
the dryland research workers: i). to identify suitable crops and<br />
varieties for early, normal and late commencement of sowing<br />
rains, ii). to identify and match intercropping systems with the<br />
rainfall pattern), iii). determine optimum sowing periods for<br />
different crops and cropping systems, and iv). to assess the<br />
amounts of inevitable runoff available for water harvesting<br />
and recycling in arid, semiarid and sub-humid regions of the<br />
country. Weekly water balance computations were carried out to<br />
determine the water availability periods for crop growth, based<br />
on which, suitable cropping systems (mono, inter and double<br />
cropping) have been identified. The drought vulnerability of<br />
rainfed crops was assessed reflecting dates of commencement<br />
of rainy seasons, and threshold values of moisture availability<br />
for obtaining above average yields were obtained. In order to<br />
explain the patterns of rainfed crops in relation to various dates of<br />
commencement of the rainy season, crop-weather models were<br />
developed using the concept of water requirement satisfaction of<br />
the crop during its growth cycle. The probability of occurrence<br />
of different amounts of rainfall and the corresponding length of<br />
the growing season, as related to the annual rainfall could be<br />
taken as a criterion for stabilizing crop production in any region<br />
(Singh and Ramakrishna, 1993).<br />
Based on significant work during past 50 years, the long-term<br />
strategic approaches were developed to efficiently conserve<br />
and utilize rainwater on the one hand and in-season tactical<br />
50 Years of Dryland Agriculture Research in AICRPDA: An Overview<br />
approaches to mitigate the adverse effects of weather aberrations<br />
with specific management strategies. Research in this area<br />
refined or developed several crop contingency plans specific to<br />
agro climatic zones, districts or even at micro level considering<br />
rainfall variability, soil types and dominant cropping patterns,<br />
to mitigate the drought effects to a certain extent (Singh and<br />
Ramana Rao 1988). The dryland research efforts in AICRPDA<br />
could be able to generate crop contingency plans for a dry land<br />
centre’s domain (Subba Reddy et. al., 2008). Further, during<br />
2009-10, agronomists at AICRPDA centres identified crop wise<br />
contingency plans for the respective domain areas considering<br />
the weather aberrations, seasons, and predominant kharif and<br />
rabi crops with appropriate crop management strategies. Since,<br />
2010, CRIDA has been working on district level contingency<br />
plans for weather aberrations particularly drought, addressing<br />
crops, livestock, fisheries. The farming situation and dominant<br />
cropping system wise soil and crop management strategies<br />
are given for the delayed onset of monsoon (2/4/6/8 weeks’<br />
delay) and also for in season drought (early, mid and terminal)<br />
(Venkateswarlu et. al., 2011).<br />
Under National Initiative on Climate Resilient Agriculture<br />
(N<strong>ICRA</strong>), since 2011, initiated both on-station research and<br />
on-farm demonstration of real-time contingency plans at 23<br />
AICRPDA Network centres. Real Time Contingency Planning<br />
(RTCP) is considered as “Any contingency measure, either<br />
technology related (land, soil, water, crop) or institutional and<br />
policy based, which is implemented based on real time weather<br />
pattern (including extreme events) in any crop growing season”<br />
(Srinivasarao et. al., 2016). The on-farm program is being<br />
implemented in 54 adopted villages in 26 districts covering 15<br />
states. Since 2011, the AICRPDA-N<strong>ICRA</strong> programme is being<br />
strengthened at network centres to address the emerging location<br />
specific weather aberrations such as delayed onset and in-season<br />
droughts in the domain of majority of the centres, excess rainfall<br />
events at specific locations and droughts and floods in north<br />
bank plain zone of Assam. The RTCP implementation was with<br />
two-pronged approach i.e., preparedness and real-time response.<br />
Identified suitable crops and varieties to cope with delayed onset<br />
of monsoon: For example, at Indore, for 14 delay in soybean<br />
cv. RVS 2001-4, JS 335, pigeonpea cv. C 11, ICPH-2671; at<br />
Biswanath Chariali for 18 days’ delay, rice cv. Gitesh Ranjit; at<br />
Parbhani for 18 days’ delay, pigeonpea cv. BDN 711; at Rajkot<br />
for 25 days’ delay cv. groundnut cv. GG 20, sesame cv. G<br />
Sesame 2 and castor cv. GCH 7; at SK Nagar for 21 days’ delay,<br />
pearlmillet cv. GHB 558, greengram cv. GM 4 etc. Developed<br />
46 real-time contingency measures (soil, water and crop based)<br />
to cope with early, midseason and terminal drought in rainfed<br />
crops (Neog et. al., 2016; Neog et. al., 2020; Ravindra Chary<br />
et. al., 2013; Ravindra Chary et. al., 2020; Gethe et. al., 2021).<br />

Soil management<br />
Integrated nutrient management (INM) studies have established<br />
the value of several naturally occurring nutrients containing<br />
(organic manures) and generating (biofertilizers) sources to<br />
augment overall nutrient turnovers for soil fertility management.<br />
Green manure was found to be a dependable source of several<br />
plant nutrients. Typically, it could meet half the N requirements<br />
of a crop. Inclusion of legumes in a rotation benefitted the<br />
succeeding crop equivalent to 1030 kg N ha 1 . Short duration<br />
legumes such as cowpea benefitted much more. An integration<br />
of FYM (10 t/ha) + recommended NPK at Bangalore not only<br />
stabilized productivity and improved sustainability but also<br />
improved economics of production. INM in combination with<br />
legume-based crop is recommended for higher productivity.<br />
INM systems, besides nutrient supplementation, enhanced<br />
soils’ ability to hold additional water and produced resulted<br />
in favourable soil biological interactions. Schemes to generate<br />
green manure in a non-competitive way during the no cropping<br />
season and bund farming have been worked out. This has<br />
opened a new vista to make green manuring a viable option.<br />
Long term INM trials conducted for more than 20 seasons at<br />
AICRPDA centres indicated that fertilizer cost can be reduced by<br />
substitution of fertilizer with organics. In most of the situations,<br />
the yield sustainability was higher when the recommended<br />
dose of fertilizer was applied. Further, in case of cereals,<br />
higher sustainability was obtained when the recommended<br />
dose of nutrients was applied through chemical sources. In<br />
case of oilseeds, however, the recommended dose applied half<br />
through chemical fertilizer and the other half through organic<br />
source led to higher sustainability values. Available nitrogen,<br />
organic carbon and phosphorus content in soil were increased<br />
with organic fertilizer application. Application of crop residues<br />
in combination with chemical fertilizer resulted in higher<br />
sustainable yield and maintained higher levels of nitrogen,<br />
phosphorus and organic carbon. Green leaf manure proved<br />
promising in increasing the sustainability in yield and improving<br />
the organic carbon, infiltration rate and hydraulic conductivity<br />
of the soil (Vittal et. al., 2005).<br />

Soil organic C stocks decreased with depth in the profile,<br />
whereas inorganic C stocks increased with depth. Among<br />
the production systems, soybean-, maize-, and groundnutbased<br />
systems showed greater organic C stocks than other<br />

to 0.34% at Varanasi due to different INM practices. The<br />
carbon footprints (Tg CE ha -1 year -1 ) were higher in cereals<br />

Identified key soil quality indicators in diverse rainfed<br />
agroecologies: Organic carbon (OC), available N, P, K, S,<br />
exchangeable Ca, Mg and DTPA extractable Zn emerged as<br />
key chemical soil quality indicators in most of the rainfed<br />
soils. Among the set of biological and physical soil quality<br />
indicators, dehydrogenase activity, microbial biomass carbon<br />
and labile carbon, bulk density and mean weight diameter<br />
(soil structure) figured as predominant indicators. Based<br />
on soil quality indices, best soil and nutrient management<br />

Farm mechanization in rainfed cropping systems:<br />
Mechanization of drylands reduced 20-59% operation cost,<br />
saved 45-64% in operation time, saved 31-38% seed &<br />
fertilizer and increased productivity of dryland crops by 18<br />
to 53%. The energy requirement of major farm operations<br />
in dryland agriculture was worked out. Anantapur and<br />
Bengaluru centres developed energy efficient bullock/<br />
tractor drawn implements/machinery for various agricultural<br />
operations. Complete farm mechanization package is<br />
developed for groundnut, rabi sorghum, maize and chickpea<br />
at various centres. The project over a period of time worked<br />
on suitable implements for mechanization of various<br />
agricultural operations. This reduced 20-59% operation<br />
cost, saved 45-64% in operation time, saved 31-38% seed<br />
& fertilizer and increased productivity of dryland crops by<br />
18-53%.<br />
Alternate land use systems<br />
In the Post 1987 era, the dryland agriculture research was much<br />
important due to shift from field crops to dry land horticulture<br />
plantation, particularly in shallow and slopy lands. The various<br />
alternate land use options were made available viz. agro-forestry<br />
systems (alley cropping, agri-horticulture, horti-pastoral system,<br />
agri-silvi-pasture system,), intercropping with nitrogen fixing<br />
tree species (NFTs) and ley farming in arable lands; and tree<br />

farming/woodlots, range/pasture management, silvi-pastoral<br />
management system, timber and fibre (Timfib) system in<br />
culturable waste and marginal lands (Singh and Osman, 1995).<br />
Techniques for rehabilitation of marginal lands for planting<br />
annual and perennial crops by restructuring the planting site<br />
were devised through fertility improvement by addition of<br />
tank silt, composted/farmyard manure, black soil etc. With<br />
planting site improvement, a noticeable improvement in crop<br />
establishment, survival and yielding ability occurred. Systematic<br />
designs were developed and improved to suit agroforestry.<br />
Management practices such as mulching, water harvesting, and<br />
soil amendments were evolved for marginal lands for improved<br />
survival of horticultural and forest tree species. Horti-pastoral<br />
system was identified as one of the potential alternative land<br />
use system options in shallow to medium deep soils to meet<br />
the growing demand of fruit and fodder, particularly to small<br />
ruminants. Studies have indicated that ring weeding and in situ<br />
moisture conservation besides micro site improvement were<br />
essential to improve the survival of fruit tree seedlings in dry<br />
lands (Subudhi and Behera, 2008). Water supply to the plant<br />
can be improved by water harvesting using in situ or ex situ<br />
system. At Hyderabad, micro reliefs of 3 m width and 25 cm<br />
height, spaced 9 m from ridge, have been used to store extra<br />
rainwater for fruit trees such as kagzi lime, Coorg mandarin,<br />
and sweet orange with tomato and okra as intercrops (Singh and<br />
Vishnumurthy,1988).<br />
A number of promising alternate land use systems were<br />
identified for different rainfall zones and soil types which<br />
included agri-silviculture, agri-horticulture and silvi-pasture<br />
systems: Aonla + greengram fodder in kharif and mustard in rabi<br />
at Rakh Dhiansar; Aonla + finger millet/ cowpea at Bangalore;<br />
Ley farming with Stylosanthes hamata with sorghum rotation),<br />
silivipasture with Leucaena leucocephala + Stylosanthes hamata<br />
+ Cenchrus ciliaris, agro-horticulture with guava/custard apple/<br />
pomegranate/ber based found better. The agroforestry systems<br />
developed at various Centres are given in table.<br />
Integrated farming systems research<br />
Research on integrated farming systems was started at<br />
AICRPDA centres in 1990s (AICRPDA, 2003). At Kovilpatti,<br />
an IFS model for 0.4 ha comprising sorghum+greengram (0.16<br />
ha) + maize + cowpea (0.08 ha) + clusterbean /senna (0.04 ha)<br />
+ poultry (20 broiler birds) +Kanni goats (4) + Vembur sheep<br />
(6) + dairy - cross bred cow (1) was suggested which could<br />
give more sustainability with higher net returns, employment<br />
generation and increase in soil fertility (Soliappan et. al., 2007).<br />
Other IFS modules suggested were, agroforestry+sheep based<br />
IFS at Anantapur, cereals, and most importantly at Arjia viable<br />
IFS modules were developed with the components of crop,<br />
small ruminants, agroforestry systems for small and marginal<br />
Ravindra Chary et al.<br />
16<br />
holdings, which were included in National Livelihood Mission<br />
programme in Bhilwara district (Rajasthan). The research on<br />
agroforestry systems based IFS modules (with the components<br />
of perennials, annual crops, grasses, medicinal and aromatic<br />
plants, high value crops etc.) have been in progress at AICRPDA<br />
centres and now more priority is given for identifying/<br />
developing farming situation specific IFS modules since 2006.<br />
Identified rainfed farming systems viz. at SK Nagar, integration<br />
of agricultural alone with livestock; at Bangalore, crops + dairy<br />
+ sheep + goat + poultry + sericulture + piggery; at Kovilpatti<br />
(Tamil Nadu) showed that crop + goat (4) + poultry (20) +<br />
sheep (6) + dairy (1); at Bijapur crops, horticulture, goat and<br />
poultry and at Anantapur, sheep rearing (10 no.) and groundnut<br />
cultivation (1 ha) and groundnut cultivation (1 ha) + 1 jersey<br />
cow. Identified efficient integrated farming systems modules for<br />
scarce rainfall zone of Andhra Pradesh (Gopinath et. al., 2013).<br />
Land capability based productive farming systems are identified<br />
for drought prone regions based on land capability, rainfall, and<br />
soil orders and the outcome of research information generated at<br />
AICRPDA centres (Vittal et. al., 2007).<br />
Since 2018, Rainfed Integrated Farming Systems (RIFS) onfarm<br />
research has been redesigned as a flagship programme<br />
in AICRPDA. A standard methodology was developed for<br />
inventory and characterization of traditional rainfed farming<br />
systems in each AICRPDA centre’s agro ecology. The<br />
predominant rainfed integrated farming systems (RIFSs) were<br />
characterized by surveying 5280 farmers (covering marginal,<br />
small and medium, and farming situations-rainfed and partially<br />
irrigated) by 22 centres (240 farmers each) in 132 villages of<br />
44 blocks in 22 districts across 15 states. The traditional RIFSs<br />
were analysed and identified core RIFS practiced under rainfed<br />
conditions viz. crop + large ruminants, crop + small ruminants,<br />
crop poultry, crop + horticulture + large ruminants, crop + large<br />
ruminants + small ruminants + poultry and crop + poultry. Under<br />
partially irrigated conditions, the predominant RIFS are crop +<br />
large ruminants, crop + horticulture + large ruminants and crop<br />
+ large ruminants + small ruminants + poultry. Stakeholder<br />
consultations were held in OFR-RIFS villages to prioritize<br />
component-wise interventions to strengthen traditional RIFSs.<br />
The interventions are being implemented under seven modules<br />
(as per the need) viz. NRM, crop, livestock, perennial tree,<br />
fodder, specific/optional module (interventions specific to<br />
individual farmers’ needs) and capacity building.<br />
Land use planning for management of agricultural<br />
resources in rainfed agroecosystem<br />
During 2001-2005, an entirely new approach of Crop planning<br />
as per Soil-site suitability was conceptualized under NATP-<br />
Mission Mode Project on Land Use Planning for Management<br />
of Agricultural Resources in Rainfed Agroecosystem where in
400 interventions were demonstrated on 132 soil-sub groups on<br />
varying topo-sequences in 16 micro watersheds by 13 AICRPDA<br />
centres.This provided much needed land use diversification<br />
from the traditional rainfed land utilization and indicated micro<br />
level variations of soils (phases of soil series) and management<br />
practices on a topo-sequence (Ravindra Chary et. al., 2008;<br />
Shankar et. al., 2004) are the prime factors influencing land<br />
productivity which increased from 30 to 50 per cent and in<br />
few cases more than double. The soil-site suitability criteria<br />
were developed for 41 field, horticulture and high value crops.<br />
Developed cadastral level soil-site specific cropping systems<br />
centred land use modules for higher land productivity in 19<br />
micro watersheds across rainfed agro-ecosubregions. Developed<br />
a new concept and methodology of delineating each microwatershed<br />
into homogeneous units viz., Soil Conservation Units<br />
(SCUs), Soil Quality Units (SQUs) and Land Management Units<br />
(LMUs) for soil and water conservation prioritized activities,<br />
for soil quality and carbon sequestration and for allocating land<br />
parcels to most suitable land uses (Ravindra Chary et. al., 2015).<br />
Technology assessment, refinement and development<br />
One of the core objectives of AICRPDA is to evaluate and study<br />
transferability of improved dryland technologies to farmers’<br />
fields. In this regard, the coordinated efforts by AICRPDA<br />
centres are the best model for technology assessment and<br />
refinement and also technology upscaling in diverse rainfed<br />
agroecologies. Self-evaluation through ORPs is the hallmark<br />
of AICRPDA. On-farm participatory technology development<br />
has been a continuous process and delivered effectively through<br />
ORP in developing doable rainfed technologies (Sharma et. al.,<br />
2010; Balakrishna Reddy et. al., 2013; Ramachandrappa et. al.,<br />
2014; Bhanavase et. al., 2014; Kothari et. al., 2016; Bhargavi et.<br />
al., 2019). In the ORPs, the action research has been in the real<br />
farm situations. They demonstrated the economic viability, and<br />
feasibility of the recommended location specific technology.<br />
Feedback to research was an important conduit from the ORPs.<br />
Research findings from the main centres were assessed as action<br />
research through Operational Research Projects and feedback<br />
from farmers was given to main centres for refinement, if any.<br />
The revitalization of ORPs has been done by restructuring the<br />
ORP technical programme through Participatory Research<br />
Plans (PRPs) for Participatory Technology Development and<br />
Participatory Extension Plans (PEPs) for technology upscaling.<br />
PRPs and PEP s are now embedded in technical programme of<br />
ORPs for effective implementation, monitoring and evaluation<br />
for impact (Ravindra Chary et. al., 2009). On-farm validation<br />
of contingency measures on real-time basis (delayed onset of<br />
monsoon, early/midseason/terminal drought/high intensity<br />
rainfall events). Soil moisture conservation practices on a small<br />
agricultural watershed including the development of water<br />
harvesting were also a result of the program. Another significant<br />
50 Years of Dryland Agriculture Research in AICRPDA: An Overview<br />
17<br />
achievement was quantification of intercropping systems<br />
management and farm mechanization. Over a period, ORPs<br />
could give feedback on some of the technologies for refinement<br />
and many for wider adoption. Since NRM technologies are<br />
location-specific and needed continuous evaluation. The<br />
technology assessment and development at non-ORP centres<br />
has been through on-farm trials supported by AICRPDA and<br />
externally funded projects including state /SAU funded projects/<br />
programmes.<br />
Experiences gained (Post 1987)<br />
Soil quality has been the major constraint in rainfed<br />
agroecosystems. During 2000 to till date, the research<br />
on Permanent manurial trials, INM, Tillage and nutrient<br />
management, could identify soil carbon management /carbon<br />
sequestration strategies to suit diverse rainfed agroecologies and<br />
also to enhance the crop productivity. Rainfed production system<br />
and soil-site specific soil quality indicators are identified which<br />
help in furthering the research focus on soil quality maintenance<br />
in soils of rainfed agriculture. The project since inception with a<br />
focused approach could identify/develop contingency measures<br />
to cope with drought. The recent high intensity rainfall events<br />
are recurrent during cropping season, particularly in Vertisol<br />
areas of Central India and Southern Deccan Plateau, enormously<br />
affecting production and productivity of rainfed crops. To<br />
address these issues, the research on contingency planning<br />
reoriented under N<strong>ICRA</strong> to evaluate contingency measures on<br />
real-time basis at all centres to identify the risk resilient crop/<br />
cropping systems, soil and nutrient management practices to<br />
cope with delayed onset of monsoon and in season drought.<br />
The impact of these studies indicated preparedness through<br />
rainwater harvesting and efficient utilization through life<br />
saving/supplemental irrigation, in situ conservation measures<br />
such as broad bed furrow, ridge and furrow system etc. enabled<br />
with energy efficient farm implements, short duration drought<br />
tolerant varieties and intercropping systems and implementation<br />
of contingency measures on real-time basis during delayed<br />
onset of monsoon and early/midseason/terminal droughts with<br />
various soil, crop and energy management strategies could<br />
enhance productivity and bring in resilience, to some extent, to<br />
the production system. However, timely availability of seed of<br />
contingency crop/variety and in desired quantity, availability<br />
of materials of foliar sprays, stored rainwater for life saving<br />
irrigation when needed, farm implements to take up sowings in<br />
large area within the limited moisture availability window are<br />
some of the major constraints in implementation of real-time<br />
contingency plans.<br />
Sustaining the rainfed agriculture with stable productivity and<br />
profitability is the major concern. The research on alternative<br />
land use systems for stabilizing and maximizing productivity<br />
could be able to develop some agroforestry models matching
specific agro-ecologies. Crop-livestock based farming systems<br />
have been the sustaining the rained farmers for their income and<br />
livelihood. With animal population dwindling and with forced<br />
non-farm income activities, the research focus is strengthening<br />
traditional arming systems with suitable components that<br />
enhance productivity, income and livelihoods and also act<br />
as adaptation/risk resilient strategy towards climate resilient<br />
rainfed agriculture.<br />
Dryland technologies, which are primarily “natural resource<br />
centered” have to address the challenges of rainfall variability/<br />
drought, land/soil quality deterioration, enhancing crop<br />
productivity for stabilizing production in diverse biophysical<br />
and socioeconomic settings of dryland agriculture. Over a<br />
period, it has been a daunting task for the project to generate<br />
dryland technologies as a package. Yet, the project succeeded<br />
in developing doable agroecology specific rainfed technologies<br />
that resulted in higher water/land productivity, enhance or<br />
maintain soil health, carbon sequestration, mechanization of<br />
dryland farming to some extent. However, as a System approach,<br />
the research in the project needs to be strengthened, may be with<br />
more human resources with needed expertise and knowledge,<br />
advanced research facilities and no doubt with high investment.<br />
Participatory technology development (PTD) is a continuous<br />
process in dryland agriculture research and development. With<br />
institutionalization of On-farm research at all the regular centres<br />
paved the way for technology assessment, refinement and<br />
upscaling under real-farm situation. Further, this mechanism<br />
also helped in on-farm participatory research on Integrated<br />
farming systems.<br />
As far as technology upscaling is considered, the convergence<br />
mechanism needs to be strengthened since NRM technologies<br />
are “Capital intensive” which need multi-programme and multiinstitutional<br />
strong collaboration ensuring the participation of<br />
primary stakeholders i.e., farmers, with much needed institutional<br />
and policy support from time to time for investments in dryland<br />
agriculture development.<br />
Future thrust areas in dryland agriculture research<br />
The major challenges for sustainable dryland agriculture are<br />
natural resource degradation, climate change, increasing food,<br />
feed and fodder demand and slow growth in farm income.<br />
These challenges demand a paradigm shift in formulating and<br />
implementing the dryland agricultural research programmes.<br />
Some perspectives as well as proposals for future dryland<br />
agriculture research are:<br />
i) Addressing the challenges and opportunities facing the<br />
food and agriculture system: Focus of dryland agriculture<br />
research to be more on adaptation. . Innovation efforts should<br />
include focus on new crop varieties, crop protection, innovative<br />
rainwater management, responsible use of fertilizers, soil<br />
Ravindra Chary et al.<br />
18<br />
conservation, and adjustment in farming practices, etc. Increasing<br />
farm productivity on existing land should be a top policy priority<br />
as it is the most productive and environmentally friendly option<br />
available, and will address issues such as biodiversity, carbon<br />
sinks etc.<br />
ii) Food security and environmental protection are not<br />
mutually exclusive goals: Integrated agriculture based on the<br />
judicious use of technology and inputs (such as seeds, manure,<br />
fertilizers and crop protection products) and good agricultural<br />
practices can increase farm production in a sustainable way. So<br />
there is an urgent need to develop appropriate technologies for<br />
precision farming.<br />
iii) Agro-ecology specific resilient integrated farming<br />
systems: Dryland agriculture research has a key role to play<br />
in the innovative research needed to transform agricultural<br />
production systems in future. New food production models will<br />
have to be considered that will take account of ever decreasing<br />
resources while at the same time providing ever increased levels<br />
of output. Developing these new systems will result in a different<br />
approach to farming practices and the natural environment, the<br />
challenge being to develop integrated crop- tree-fodder-animal<br />
systems that increase agricultural output whilst simultaneously<br />
advancing environmental, economic and social goals. Focus<br />
should be on developing risk resilient and sustainable dryland<br />
farming systems.<br />
iv) Sustainable intensification: The concept of ‘sustainable<br />
intensification’ refers to the process of increasing agricultural<br />
yields without adverse environmental impact and without the<br />
cultivation of more land. This concept underlines the approach<br />
required by dryland agriculture research to the challenges<br />
outlined above. Dryland agriculture research must strive to<br />
develop new production technologies and approaches that<br />
maximize the benefits of natural resources while protecting and<br />
restoring these resources for future use. There must be a broad,<br />
inter-institutional and multidisciplinary approach to address<br />
these challenges in terms of crop diversification, enhanced food<br />
safety, improved natural resource management, biodiversity<br />
protection, climate change adaptation, energy security and meet<br />
the demand for environmental goods and services.<br />

Email: sarmahpk@gmail.com<br />
Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Centre at Jorhat under Assam Agriculture University<br />
was started in 2005. Later, in 2010, the Centre was shifted to<br />
the present location at Biswanath Chariali which is located in<br />
Biswanath District in North Bank Plains Zone of Assam. The<br />
Centre is catering to the dry land research needs of North Bank<br />
Plain Zone (NBPZ) of Assam and the state in general since 2010.<br />
Agro-climatic zone characteristics<br />
The zone belongs to NARP Agro-climatic Zone ‘North Bank<br />
Plains Zone (NBPZ) with six domain districts viz., Darrang,<br />
Udalguri, Sonitpur, Biswanath, Lakhimpur and Dhemaji. The<br />
climatic of the zone is sub-tropical having hot and humid<br />
summer, dry and cold winter and high relative humidity.<br />
Summer is experienced from May to August, cold winter from<br />
December to January and a mild winter is experienced from<br />
September to November and February to April. The zone<br />
receives an average annual rainfall of 1980 mm while during<br />
pre-monsoon (March-May), monsoon (June-September), postmonsoon<br />
(October-November) and winter period (December-<br />
February), the average rainfall received is 486.5 mm (24.57%),<br />
1279 mm (64.64%), 150.3 mm (7.59%) and 63.3 mm (3.20%),<br />
respectively. The average maximum temperature is recorded<br />
in July-August (about 33-34 ° C during 28 th to 34 th SMW) and<br />
minimum temperature (6.9-8.2 ° C during January). July and<br />
August month are the hottest months and January-February<br />
are the coolest months. Flood is common in every year and<br />
sometimes flood occurs even in September in Dhemaji and<br />
Lakhimpur districts. Approx. 105 days rainy days per year is<br />
generally experienced in the North Bank Plan Zone of Assam.<br />

Major soil types<br />
The major soil types in the zone are sandy loam and clay loam<br />
soils.<br />
Major rainfed crops<br />
The major rainfed crops cultivated in the zone during kharif are<br />
Sali rice, Boro rice, Bao rice, maize, greengram, blackgram and<br />
sesamum, during rabi are toria, jute, pea, sugarcane and potato<br />
and during autumn Ahu rice.<br />
Dryland agriculture problems<br />
The major problems of dryland agriculture in domain districts<br />
of the centre are<br />
Weather aberrations<br />
● Recurring flood during the monsoon season leading to<br />
extensive damage of crop fields. Prolonged dry spells during<br />
rabi season leading to poor crop yields and non-remunerative<br />
crop production.<br />
Soil and land management related<br />
● Predominance of acid soils resulting in low crop productivity<br />
● Injudicious application of agro-chemicals leading to soil<br />
degradation<br />
● Sand casting of agricultural field in Dhemaji and Lakhimpur<br />
districts resulting in conversion of fertile agricultural lands<br />
to unproductive land.<br />
Socio-economic factors<br />
● Predominance of small and marginal farmers hinders<br />
adoption of modern technology in agriculture<br />
● Fragmentation of land holdings and practice of monocropping<br />
● Non-adoption of community farming<br />
● Lack of adequate farm mechanization due to non-availability<br />
of suitable agricultural machineries for cultivation in small<br />
land holdings.<br />
● Market risks<br />
● Non-availability of quality seed/planting material of<br />
improved crop varieties<br />
● Underdeveloped livestock and fishery sectors<br />
Research initiatives since inception of the centre<br />

The North Bank Plains Zone (NBPZ) of Assam consists of<br />
6 districts viz., Dhemaji, Lakhimpur, Biswanath, Sonitpur,<br />
Darrang and Udalguri. The zone covers a total area of 14.42<br />
lakh ha with dominant upland situation. The Centre is presently<br />
undertaking research activities in diverse rainfed agro-ecologies<br />
of NBPZ of Assam and a multidisciplinary team of agronomist,<br />
soil scientists and water conservation engineer are involved in<br />
the need based location-specific research. The hallmark of the<br />
programme is the need based location-specific research of small<br />
and marginal farmers based on natural resource management and<br />
socioeconomic status. The on-station trials of AICRPDA center<br />
are carried out in the experimental farm of Biswanath College<br />
of Agriculture which represents the upland situation. The rice<br />
based cropping system research under midland and lowland<br />
situations is carried out at Regional Agricultural Research<br />
Station, North Lakhimpur, as well as at research field of Krishi<br />
Vigyan Kendra, Sonitpur under Assam Agricultural University<br />
(AAU), for development of technologies for medium/lowland<br />
situations of the zone. The collaborative on-station and onfarm<br />
technology assessment and refinement is carried out in<br />
six agroclimatic zones of Assam both at Regional Agricultural<br />
Research stations and Krishi Vigyan Kendras of AAU for<br />
inclusion of suitable rainfed technologies in state package of<br />
practices which is a joint venture of Department of Agriculture,<br />
Assam and AAU. The technologies are subsequently included<br />
in various extension programmes for various projects of<br />
government of India implemented by government of Assam<br />
through state Department of Agriculture, AICRPDA, N<strong>ICRA</strong>,<br />
TSP, various AICRP projects and NABARD.<br />
Significant achievements<br />
Resource characterization<br />
Agro-climatic resource characterization and crop planning of<br />
Sonitpur district revealed that the annual rainfall varied from<br />
1358 mm (2001) to 2573 mm (2004) with mean value at 2027<br />
± 55.54 mm. The rainy season in the region starts in mid-March<br />
and quantum of rainfall as well as number of rainy days increases<br />
gradually and reaches maximum in the month of July and then<br />
decline to minimum during November/December. During the<br />
study period, highest monthly rainfall recorded was 668 mm in<br />
the month of July. June and July were the wettest months (362<br />
mm) while December (11 mm) was the driest month. Coefficient<br />
of variation (CV) of monthly rainfall from April to September<br />
was less than 50 which reveals that rainfall during these months<br />
are almost stable.<br />
The seasonal and annual rainfall of the zone was verified with<br />
Mann-Kendall trend test and Sen’s slope estimator for the<br />
period of 1984 to 2016. A significant decreasing trend of annual<br />
and monsoon rainfall with slope magnitude of -15.09 mm / yr<br />
and -29.03 mm / yr, respectively, was identified and a positive<br />
Sarma et al.<br />

significant trend of coefficient of variation of monthly rainfall<br />
for a 10-year moving period was observed for the month of June<br />
(R 2 = 0.63), September (R 2 = 0.59) and October (R 2 = 0.57).<br />
The study indicated that the rainfall fluctuations with large<br />
amplitudes and increasing frequency of intermittent dry spells<br />
and flash floods in the region has been increasing and also likely<br />
to increase in future.<br />
Analysis of 27 years (1984-2012) rainfall data of NBPZ showed<br />
that seasonal drought occurred in both kharif and rabi season,<br />
however frequency of occurrence of drought was more in rabi<br />
as compared to kharif season. It was also found that the longest<br />
agricultural drought of 4 weeks was experienced during kharif<br />
season, while in rabi, the drought was mostly prolonged for 5<br />
weeks and in some case, it continued up to 11 weeks. The rainy<br />
days with more than 100 mm rainfall in the region has been<br />
increasing, though it is not statistically significant. Decadal<br />
change in CV of monthly rainfall during June and September<br />
in the region was observed to be remarkable. It was observed<br />
that number of dry spells (early, mid and late season) and flash<br />
floods in the region have been increasing. The region suffered<br />
from early, mid and late season drought in recent years 2001,<br />
2005, 2006, 2009, 2011, 2013, 2014, 2015 and 2016.<br />
Rainwater management<br />
A concrete rainwater harvesting structure was constructed<br />
during 2012-13 having catchment area of about 320 m 2 with<br />
maximum water storage capacity of 528.26 m 3 , for covering<br />
a command area of about 6000 m 2 for data generation on<br />
catchment-storage-command area relationships and to develop<br />
farm pond technology for the domain districts. The evaporation<br />
was 40-43.5% of the total stored water and seepage is<br />
considered to be negligible (concrete lining), whereas, the dead<br />
storage were observed to be around 17-33.22%. The lifesaving<br />
irrigation (3-5 cm) is applied mainly through drip irrigation, and<br />
sprinkler irrigation systems or with the hose pipes as well, in<br />
the crops based on the 10-days continuous dry spell during the<br />
crop period. The average amount of water used for irrigation<br />
during a year is 200-250 m 3 , for the crops with 300% cropping<br />
intensity. The monthly PET of the station was calculated and<br />
the average of annual PET was found to be 1138 mm, which<br />
is lesser by 887 mm as compared to the normal annual rainfall.<br />
Thus, the region has high rainwater harvest potential (887 mm<br />
annually). Normally, from March to October there was surplus<br />
water (935 mm) which is known as humid part of the year while<br />
total crop growth period is even longer. With 50% probability<br />
level of rainfall there was 884 mm excess water and with 75%<br />
probability the excess amount of water was about 40 mm. The<br />
excess water can be harvested and can be used for irrigation not<br />
only to rabi crops but also for irrigating rice crop during dry<br />
spells. The rainwater collected from a catchment area of 224<br />
m 2 (a roof area of 124 m 2 of a house + pond top surface area
of 100 m 2 ) was sufficient to harvest rainwater of 319 m 3 in a<br />
farm pond of same volume. The water collected in the pond<br />
was sufficient for providing two irrigations (0.06 m depth)<br />
in the potato crop cultivated in the area of 1840 m 2 , resulting<br />
in an increase in the tuber yield by 136% as compared to the<br />
rainfed potato crop (52.43 q/ha). Supplemental irrigation by<br />
using harvested rainwater resulted in higher yield of 14,179 kg/<br />
ha (85.6% increase) and 894 kg/ha (107% increase) in case of<br />
potato (Kufri Jyoti) and rapeseed (TS-36), respectively. Based<br />
on the on-station study during 2013-15, the polythene sheet<br />
lining was found to be the best over the other lining materials<br />
viz., cow dung + soil plaster (2:5 ratio) and cement + soil plaster<br />
(2:10 ratio). With a rainwater harvest potential of 2.45 ha-cm in<br />
cement lined tank, 2.07 ha-cm harvested rainwater can be used<br />
to irrigate potato land of 0.99 ha, 0.31 ha and 0.21 ha by one, two<br />
and three times irrigation at 25, 25 & 60 days; and 25, 60 & 80<br />
days after planting, respectively.<br />
Mulching-cum-manuring with locally available agricultural<br />
waste materials and weeds like rice straw, straw of rapeseed,<br />
water hyacinth etc is proved to be useful for management of<br />
intermittent dry spells in both kharif (turmeric and ginger) and<br />
rabi (tomato and potato) seasons. In potato, labour requirements<br />
were reduced considerably as intercultural operations like<br />
earthling up, weeding and irrigation need not be performed in<br />
mulched crop. It was observed that mulching in tomato not only<br />
assist in the better growth of the crop, but also considerably<br />
increase the length of fruiting (harvesting) period of the crop as<br />
compared to the crops grown without mulching. Combination of<br />
lifesaving irrigation and ridge and furrow systems gives better<br />
system yield and RWUE in both the greengram and blackgram<br />
cropping systems over the flat bed and control.<br />
Cropping systems<br />
Overview of Dryland Agriculture Research and Achievements in North Bank Plain Zone of Assam<br />
Under cropping system research, experiments were conducted<br />
mostly on intercropping and sequential cropping with 300%<br />
cropping intensity. The 300% cropping intensity trial was<br />
formulated including cereal crop, pulses and oilseeds with<br />
medium and short duration varieties of the respective crops<br />
developed from Assam Agricultural University. From the onstation<br />
trial of 3 years results and multi-location trial (MLT) and<br />
on-farm trial (OFT), some of the technologies have been included<br />
in package of practices. In groundnut-based cropping system,<br />
broad bed & furrow (bed size of 150-30 cm) recorded highest<br />
system yield and B:C ratio. Among the cropping sequences,<br />
groundnut- rajmah sequence was found better as compared to<br />
other sequences. Among the intercropping systems evaluated,<br />
highest system productivity and B:C ratio was recorded in rajmah<br />
+ lentil (1:1) followed by rajmah+ linseed (2:1) system. In maize<br />
based triple cropping systems under rainfed upland situations,<br />
maize+ greengram (paired row) - rajmah – blackgram sequence<br />
was found better followed by maize+ blackgram (paired row)<br />
25<br />
- rajmah – greengram sequence. In the medium land situation<br />
of KVK, Sonitpur, rice-toria sequence gave the highest system<br />
yield in conventional tillage (CT) transplanted Sali rice- zero<br />
tillage (ZT) toria followed by CT wet DSR – ZT toria. However,<br />
CT wet DSR – ZT toria gave the highest B:C ratio. In upland<br />
situations of the Biwanath Chariali, system yield of minimum<br />
tillage (MT) maize -ZT Greengram- ZT toria was found to be at<br />
par with CT maize-CT green gram-CT toria. However, in terms<br />
of B:C ratio, MT maize -ZT green gram- ZT toria was better<br />
than the conventional system.<br />
Nutrient management<br />
In a permanent manurial experiment, application of 75% RDF<br />
+ 3 t/ha vermicompost in each crop gives the highest system<br />
yield and B:C ratio in both the cropping sequences (rice –<br />
grreen gram-toria and maize-green gram-rajmah) in the rainfed<br />
upland situation of the NBPZ of Assam. This was followed by<br />
application of 50% RDF + 3 t/ha vermicompost in each crop<br />
which was at par with 75% RDF + 1 t/ha vermicompost in each<br />
crop. However, in terms of B:C ratio, application of 75% RDF<br />
+ 1 t/ha vermicompost in each crop was more beneficial than<br />
50% RDF + 3 t/ha vermicompost in each crop. Manure addition<br />
significantly improved the soil physico-chemical and biological<br />
properties, and sequestrated organic C in soil compared to<br />
control and RDF treatments.<br />
Alternate land use<br />
Under alternate land use system four intercrops (Assam lemon,<br />
Colocasia, ginger and fodder congosignal) are being evaluated to<br />
study the interaction effect with Gmelina arborea (Gomari) and<br />
Michelia champaca (Titachopa). The study revealed that Gomari<br />
performed better in terms of growth parameters viz. height,<br />
collar diameter and canopy spread as compared to titachopa.<br />
Higher yield was observed in intercrops grown under titachappa<br />
as compared to the intercrops grown under Gomari. This may be<br />
due to higher shading effect of Gamari than Titachappa.<br />
Energy management<br />
In groundnut, two harrowings and one pulverization with power<br />
tiller resulted in higher crop yield and energy use efficiency<br />
(3.64%) compared to conventional tillage which recorded the<br />
lowest energy use efficiency of 0.22%.<br />
Evaluation of improved varieties<br />
In a varietal evaluation programme on pigeonpea, BAC 1<br />
(Biswanath Arhar Collection 1), matured in 250-260 days<br />
exhibited highest seed yields followed by BAC 2, compared<br />
to recommended variety T21. An early maturing pigeonpea<br />
variety ICPL 88039 (matured in 150 days) exhibited lower<br />
but comparable seed yield than recommended variety. The<br />
observations indicate that ICPL 88039 is a promising early<br />
maturing pigeonpea genotype for the region under normal
sown condition. Rice var. Dehangi is found suitable for rainfed<br />
upland direct seeded condition over the checks Banglami and<br />
Rangadoria in the NBPZ. A medium duration rice variety, TTB<br />
404 performed the best followed by Komal, Satyaranjan and<br />
Chandrama. The observations indicated that there is possibility<br />
of identifying better varieties than the existing recommended<br />
and cultivated varieties in the medium duration group even with<br />
lesser maturity duration. A bulk population of Niger viz. NB-1<br />
has been developed which exhibited higher seed yield than the<br />
recommended variety NG 1.<br />

b. Crop, soil, water and nutrient management strategies<br />
during seasonal drought<br />
Early season drought<br />
Upland situation<br />
Rice: Clay or clay loam with pH 4.5-6 is suitable for rice<br />
cultivation. Application of 5 cm irrigation water 3 days after<br />
disappearance of ponding water is recommended in medium and<br />
heavy soil. In kharif rice, height of bunds should be 30 cm to<br />
retain rain water for higher yield. N, P O and K O of Sali rice<br />
2 5 2<br />
60:20:40 and 20:10:10 for semi dwarf and tall varieties along<br />
with 10 t FYM per ha has to be applied during land preparation.<br />
Potato: Well drained sandy loam and loam soil, rich in organic<br />
matter are suitable. Water management: furrow method of<br />
irrigation has to be applied. Three irrigations should be applied,<br />
1 st nd<br />
at 25 days (stolon formation stage), 2 at 60 days (tuber<br />
formation stage) and 3 rd at 80 days (tuber development stage).<br />
For rainfed condition, N, P O and K O of 60:50:50 and for<br />

Rapeseed-Mustard: Sandy soil to light soil is suitable for<br />
growing of rapeseed and mustard. Water management: 6 cm<br />
depth of water may be applied at 50% flowering and at early<br />
siliqua formation stage. In case a rainfall of 20-25 mm is received<br />
during this period, no post irrigation is required. For rapeseed,<br />
N, P O and K O of 40:35:15 and 60:40:40 & Borax of 10 kg/ha<br />
2 5 2<br />
is recommended for rainfed and irrigated condition, respectively<br />
along with 2-3 t FYM per ha. For mustard N, P O and K O of<br />
2 5 2<br />
80:40:30 & Borax of 7.5 kg/ha along with 2-3 t FYM per ha has<br />
to be applied during land preparation is recommended.<br />

available<br />
● Incorporation of MOP 22.5 kg/ha in medium and lowland<br />
situations<br />
● Spray of 1% KCl solution at flowering stage and 2% urea<br />
spray at pod initiation stage of pulses<br />
● Spray of 2% KCl solution in rice as and when dryspell<br />
appears before flowering<br />
● Life-saving irrigation, if available from harvested rainwater<br />
● Harvest the crop at physiological maturity stage.<br />
c. Suggested contingency measures for transient water<br />
logging/partial inundation situation<br />

Impact of technologies<br />
Three technologies are included in state package of practices<br />
viz., optimum planting time for small tubers potato cultivars,<br />
maize based cropping sequence under rainfed upland conditions<br />
of Assam and intercropping of sesamum with green gram and<br />
black gram. The developed technologies are being upscaled<br />
for enhancing crop productivity by replacing traditional<br />
cultivation practices. Two technologies have been developed<br />
and recommended for inclusion in state package of practices<br />
where AICRPDA scientists collaborated viz, application of<br />

acceptance among the farmers.<br />
The centre contributed and played major role in development<br />
of the contingency plans for the domain districts in particular<br />
and state in general in collaboration with ICAR- CRIDA,<br />
Hyderabad. Demonstrations of climate resilient technologies<br />
generated by the centre and technology developed at AAU<br />
have made significant impact on the livelihood of the farmers<br />
of the adopted villages under N<strong>ICRA</strong> and TSP. The villages<br />
adopted under TSP, N<strong>ICRA</strong> and N<strong>ICRA</strong> upscaling programme<br />
have contributed towards horizontal spread of technology<br />
to nearby areas in terms of improved seed as well as other<br />
improved technologies. Further, on-farm demonstration of the<br />
technologies developed under AICRPDA and disseminated<br />
in collaboration with KVKs have aided in spread of improved<br />
technologies among the farmers of the domain districts as<br />
well as the state. Dissemination of weather-based advisories<br />
in collaboration with GKMS, department of agro-meteorology<br />
have benefited the farmers of the domain districts in adopting<br />
timely contingency measures which have helped the farmers in<br />
realizing higher income from the farming enterprises.<br />
Demonstration of climate resilient technologies through<br />
exhibition of N<strong>ICRA</strong> model in state and national levels have<br />
generated awareness amongst the farmers, scientist and policy<br />
makers regarding various climate resilient technologies suitable<br />
for Assam in particular and the NE India in general. Identification<br />
of various adaptation strategies including climate-resilient crops<br />
and cultivars, rainwater harvesting and recycling, efficient<br />
energy management through farm mechanization, dissemination<br />
of weather information, and weather-based agro-advisories to<br />
farmers on a real-time basis is important adaptation technologies<br />
for climate resilient agriculture. Adoption of climate resilient<br />
crops and cropping systems and use of harvested rainwater<br />
resulted in a 12 to 30% increase in yield with cultivation of highyielding<br />
rice varieties (HYVs) (Ranjit, Gitesh, Mahsuri, etc.)<br />
29
when sown in time (before 15 th June) over late sowing conditions<br />
(after 20 th June). In case of early season drought, replacement<br />
of long duration traditional varieties with short duration HYVs<br />
and providing life-saving irrigation using harvested rainwater<br />
increased yield by about 59% (short duration var. Dishang) over<br />
farmers’ method. In case of mid-season and terminal drought,<br />
application of an additional dose of 22 kg/ha MOP at maximum<br />
tillering to grain growth period increased rice yield by about<br />
33% (Ranjit), 32% (Gitesh), 64% (Shraboni), and 57.5%<br />
(Mulagabharu) over farmers’ practice. In flood-affected areas<br />
under lowland situations, cultivation of submergence tolerant<br />
varieties (Jalashree and Jalkuwari) resulted in higher yields.<br />
Dissemination of agromet advisory service to the farmers helped<br />
in the decision-making process in the preparedness stage of<br />
real-time contingency planning such as land-related (e.g., land<br />
situation wise decision making), rainwater harvesting (mulching,<br />
farm pond, micro-irrigation system, etc), crop-related (selection<br />
of suitable crops/varieties), management related (management<br />
of insect-pests, diseases, nutrient, weed, etc).<br />
The TSP programme by AICRPDA centre, Biswanath Chariali<br />
was implemented in village Jalakiasuti, Sissiborgaon block,<br />
Dhemaji district, Assam. Implementation of the project resulted<br />
in successful adoption of Custom Hiring Centre, low-cost<br />
vermicomposting technology, HYVs of crops etc. Income from<br />
tertiary occupation like production and sale of Eri yarn, sale of<br />
carpets, tie and dyed products etc. played a major role towards<br />
self-sufficiency. Introduction of upgraded pig breed (Hampshire<br />
cross) and goat breed (Beetle) improved the economy of farmers<br />
through increased meat production and breed upgradation<br />
of local livestock population. Empowerment of women folk<br />
through allied activities like mushroom cultivation, rearing dual<br />
purpose poultry Vanaraja and Khaki Campbell duck resulted in<br />
enhanced household income.<br />
Way forward<br />
Assam agriculture is mainly rice-centric. Out of net sown area of<br />
26.99 lakh ha, total area under rice in Assam is 23.6 lakh ha. Out<br />
of 26.99 lakh ha of net sown area, net irrigated area in Assam is<br />
only 2.54 ha. Therefore, more focus should be given on rainfed<br />
rice based cropping systems for sustainability of the production<br />
system. Moreover, Assam is highly vulnerable to vagaries of<br />
Sarma et al.<br />
climate and recent change in rainfall pattern has led to occurrence<br />
of flash flood and prolonged dry spells during the kharif season.<br />
The state agriculture is dominated by small and marginal farmers<br />
representing 18 and 36%, respectively. Therefore, technologies<br />
which address the problems of these farmers are urgent need<br />
of the hour to make agriculture an attractive proposition.<br />
Therefore, climate resilient technologies viz., varieties with<br />
submergence tolerance and drought tolerance need to be<br />
developed to address these vulnerabilities. Rainwater is the key<br />
input in rainfed agriculture. The success in rainfed agriculture<br />
lays in the wise use of natural resources, in particular rainwater.<br />
The rainwater harvesting structures have to be standardised as<br />
per the precipitation and land situations in various regions of the<br />
NBPZ in particular and the state in general. Emphasis should<br />
be on the use of various micro-irrigation methods such as drip,<br />
sprinkler and rain guns for enhancing the water use efficiency<br />
from the harvested rainwater. Research on different land<br />
configurations such as ridge and furrow bed systems, broad-bed<br />
furrow systems, raised bed furrow systems to be conducted for<br />
management of excess and deficit rainfall keeping in view wide<br />
variability in the rainfall pattern due to climate change. Even<br />
though Assam falls under high rainfall zones of India, prolonged<br />
winter dry spells make cultivation of rabi crops risk-prone.<br />
Harvesting and utilization of excess rainfall received during<br />
kharif season may boost the production of rabi crops which will<br />
also act as insurance against crop failure during kharif season<br />
due to high intensity flood. Efforts may be made to introduce<br />
millet crops particularly under intercropping and sequential<br />
cropping systems. More emphasis to be laid on low water<br />
requiring crops like buckwheat, niger, linseed etc. Research on<br />
crop residue management and crop diversification is required<br />
for sustainable land use system. Research on organic farming,<br />
conservation agriculture and natural farming to be carried out<br />
for soil carbon management and reducing GHG emissions from<br />
soils. Standardization of CA techniques with low-cost farm<br />
machinery tools for the poor and marginal farmers is the need<br />
of the hour. Work has also to be done on spray of CDM cultures<br />
for quick in situ decomposition of crop residues. Extensive work<br />
has to be done with nanofertilizers so as to improve fertilizer use<br />
efficiencies along with reducing the chemical load to the soil.<br />

Brief history of the Centre<br />
All India Coordinated Research Project for Dryland Agriculture<br />
Centre was started in 1971 at Kanke, Ranchi, Jharkhand. The<br />
location of the Centre has been shifted from Kanke to Zonal<br />
research station, Chainki during 2009. The Centre is running<br />
under the umbrella of Birsa Agricultural University, Kanke,<br />
Ranchi.<br />
Agro-climatic zone characteristics<br />
The domain districts of the AICRPDA Centre, Chainki are<br />
located in Western Plateau zone (NARP) in Jharkhand, in the<br />
Agroecological subregion 11.0 and in the Eastern Plateau and<br />
Hills agroclimatic region (planning commission). The climate<br />
of the zone is sub-humid to semi-arid. The annual rainfall varies<br />
from 800 mm to 1200 mm of which 90% is received during south<br />
west monsoon while 6, 3, and 1% during north-east monsoon,<br />
winter and summer season respectively. The normal onset of<br />
monsoon is during June and the normal withdrawal is during<br />
the first week of November. The rise in maximum mean annual<br />
temperature (2.9 o C) and decline in minimum mean annual<br />
temperature (3.60 o C) has been observed.<br />

Dryland Agriculture Problems<br />
Soil and land management related<br />
● Excess surface runoff due to undulating topography.<br />
● The upland soils are acidic, light and low in organic matter<br />
and plant nutrients<br />
● Poor fertility status of soils<br />
● Soils are generally acidic in nature having pH 5-6.5<br />
Crop production related<br />
● Primitive nature of cultivation, i.e, broad casting methods<br />
of sowing of uplands crops, such as rice, maize, pigeonpea,<br />
blackgram, sesame and niger<br />
● Lack of sate seed corporations and other recognized seed<br />
multiplying agencies<br />
● In sufficient or imbalance use of chemical fertilizer<br />
● Poor irrigation facilities<br />
● Lack of mechanization<br />
● Traditional crops/varieties/cropping system<br />
● Predominant monocropping<br />
● Weed infestation and higher incidence of disease and pests<br />
Socio-economic<br />
● Fragmented land holdings<br />
● Lack of input supply<br />
● Low adoption of improved crop production technology<br />
● Lack of credit facilities provided by the public sector banks<br />
● Poor post-harvest facilities<br />
● Less use of high yielding varieties of crops grown in the<br />
region<br />
● Problem of stray cattle<br />
Significant achievements<br />
Rainwater management<br />
●●<br />
In-situ moisture conservation measures such as land shaping,<br />
broad bed & furrow system, timely tillage and mulching<br />
improved soil moisture retention which helped germination,<br />
crop growth and reduced soil loss by providing more<br />
opportunity time for rainfall to enter into the soil. Ex-situ<br />
moisture conservation measures such as collection of excess<br />
31
ainfall from micro catchments into small ponds facilitated<br />
the supplemental irrigation in rabi and kharif crops during<br />
dry spells. Also, it has helped to grow vegetable crops of<br />
short duration. Studies in the Centre helped to estimate<br />
probability and recurrence period of droughts and heavy<br />
rainfall. Optimization of natural resources through improved<br />
land preparation, optimal use of organic and inorganic<br />
fertilizer and conjunctive use of water helped to increase the<br />
sustainability in crop production and the natural resources like<br />
rainfall, land and vegetation has been used at optimal level.<br />
Timely tillage operation has increased moisture retention of<br />
the soil and use of organic and inorganic fertilizers has helped<br />
to maintain the soil fertility. Conjunctive use of surface and<br />
groundwater has helped to maintain the water table.<br />
Cropping systems<br />
● Rice is considered as a dominant crop of the state and<br />
therefore maximum emphasis was given on rice. In the<br />
evaluation of drought tolerant lines of rice conducted during<br />
2011, the entry BVD-109 and BVD-110 (24.36 q ha -1 ) out<br />
yielded significantly in comparison of all the 15 entries<br />
tested. In rice varietal trial conducted in the year 2011, the<br />
entry Vandana was found to be higher yielder (28.34 q ha -1 )<br />
in comparison to others whereas in the evaluation of drought<br />
tolerant lines of rice during the year 2011-2012, the entry<br />
RR-616-B-2-75-2 (26.75 q ha -1 ) yielded significantly higher<br />
followed by RR-F-25 (24.71 q ha -1 ), Vandana (23.54 q ha -1 .).<br />
● Birsa Dhan 108 (matures in 70 days), Birsa Vikas Dhan 109<br />
(matures in 85 days) and Birsa Vikas Dhan 110 (matures<br />
in 95 days) of upland rice has been developed and given to<br />
the farmers. Farmers are preferring these varieties because of<br />
early maturity, high yielding and also having capabilities of<br />
tolerating drought. Birsa Dhan 108, an extra early maturing<br />
variety and very much suitable for dryland and monocropped<br />
system because second crop during rabi may be<br />
taken on residual moisture available in the field and thus help<br />
in cropping intensity. Birsa Vikas Dhan 109 and Birsa Vika<br />
Dhan-110 are promising varieties for rainfed upland ecology<br />
of rice because both are having superfine grain quality where<br />
all the varieties of rice which has been developed for this<br />
ecology are having course grain. Therefore, farmer may get<br />
good price in the market by cultivating these varieties under<br />
rainfed upland condition.<br />
● In the experiment entitled ‘Evaluation of drought tolerant<br />
lines of finger millet’ conducted continuously for four years<br />
from 2010-11, the entry GPU – 28 (30.4 q ha -1 ) followed by<br />
BBM-10 yielded (27.35 q ha -1 ) out yielded significantly in<br />
comparison of all the test entries. In multilocational trial of<br />
sorghum conducted during 2013-14 , ten entries of sorghum<br />
were evaluated for suitability of rainfed ecology of Palamau<br />
region. Out of which, CSV-20 surpassed the yield 32.58 q<br />
Akhilesh et al.<br />
32<br />
ha -1 and was also superior in comparison of all entries tested.<br />
Whereas SPV-1820 (31.95 q ha -1 ), SPV-2064 (28.26 q<br />
ha -1 ), CSV-15 (27.65 q ha -1 ) and CSH-16 (27.62 q ha -1 ) were<br />
also at par in comparison to other test entries including local.<br />
In linseed varietal trial conducted from 2011-12 and 2012-<br />
2013, the entry NL-259 (7.46 q ha -1 ) has recorded higher<br />
yield in comparison to check T-397 (6.40 q ha -1 ).<br />
● J-1 variety of groundnut was found significantly higher<br />
yielder over existing variety AK 112-24 during 1981-83.<br />
A-300 and A-1 variety of safflower were identified as drought<br />
tolerant, short duration and high yielder for this region during<br />
1990-91.BAU 149-2, BAU 148-30 and BAU 4045 variety<br />
of rice was found significantly higher yielder over existing<br />
variety brown Gora during 1999-2000. CSV-20, SPV-1820<br />
variety of sorghum were found early maturing, high yielder<br />
and suitable for drought like situation during 2008-2009. In<br />
Horse gram var., Birsa Kulthi -1, Madhu and GHG-19 were<br />
found early maturing, high yielder and suitable for drought<br />
like situation. Birsa vikas Makka-2 a composite and short<br />
duration hybrid of maize has been evolved and it matures<br />
in 80 days having plant height of 180-185 cm. Because of<br />
early maturity, it can escape drought which has become<br />
regular feature in the state. This variety has also qualified<br />
for high quality protein maize (QPM) which may provide<br />
the nutritional security to the tribal farmers of the region.<br />
The yield potential is 40-45 q ha -1 and has been found very<br />
much suitable under rainfed condition. Quality seed of high<br />
yielding varieties is being provided to the farmers and has<br />
been found promising under the farmers managed condition.<br />
The quality seed has also been found to increase the yield<br />
by 15-20% alone and if package of practices and IPM<br />
recommended by the University are followed by the farmers,<br />
the yield increase may go up to 60-70%.<br />
● The Intercropping of pigeonpea + Okra (1:1) has given<br />
maximum pigeonpea equivalent yield (2834 kg ha -1 ) which<br />
is about 100% more in comparison to pigeonpea and okra<br />
alone. This intercropping has helped farmers in increasing<br />
their livelihood. The effect of inter-row spacing and level of<br />
nitrogen on grain yield of lentil was studies and maximum<br />
grain yield 4.47 q ha -1 of lentil was observed when 30 kg<br />
N ha -1 was applied while maintaining the spacing of 30 cm<br />
from row to row. The farmers for harvesting the highest grain<br />
yield of lentil are following this recommendation. Sowing of<br />
horsegram, sorghum and gundli in case of failure of monsoon<br />
has yielded satisfactorily in the prevailing drought situation.<br />
● Sowing of early maturing varieties of kharif crop like rice<br />
which may be harvested by the end of September and rabi<br />
crop like Toria, mustard, linseed and lentil has been sown<br />
on the residual moisture available in the field. This has not<br />
only increased the crop production but also the profitability
and sustainability. Pigeonpea based intercropping with<br />
upland rice has been easily adopted with high sustainability<br />
and profitability. The rate of adoption is 40-50%. This has<br />
been very remunerative that is why farmers has attracted and<br />
adopted this intercropping.<br />
Energy management<br />
● Improved animal drawn implements like Birsa ridger plough,<br />
seed drill, dutch hoe and handy implements like grubber,<br />
improved sickle has been tested in farmers field and found<br />
suitable for increasing the operational efficiency.<br />
Technologies upscaled in convergence with various<br />
programmes<br />
The Centre is working as a nodal agency for addressing the<br />
problems related to Dryland Agriculture and contingency<br />
planning of the region. The electronic and printing media are<br />
very much helpful while covering the experimental details and<br />
publishing it in daily newspaper and also telecasted by Radio and<br />
Doordarshan. The films of the success stories are also prepared<br />
and shown to the farmers at the time of visit to the Centre. The<br />
soil testing facilities helped to know the status of nutrients and<br />
their deficiency. This helps in providing the balanced use of<br />
fertilizer for harvesting the potential yield of the crops/varieties.<br />
These outcomes have been beneficial in improving the socioeconomic<br />
condition of the farmers in general and resource poor<br />
farmers in particular because the farming community of the<br />
region has been benefited a lot by adopting the recommended<br />
variety/technology developed by the Centre. Improved varieties<br />
and its popularization improved the yield of kharif and rabi<br />
crops. Birsa seed cum fertilizer drill is very much popular in<br />
ORP village.<br />

Impact of technologies<br />
Cultivation of HYV Vandana in bunded fields yielded higher<br />
(1989 kg ha -1 ) in comparison to unbunded fields. The BC ratio<br />
Akhilesh et al.<br />
34<br />
was found maximum (1.69) in bunded condition compared<br />
to unbunded condition (1.34). Chickpea variety KPG 59 was<br />
tested with farmers variety under minimum tillage condition<br />
on available moisture after paddy harvest. Variety KPG 59<br />
produced significantly higher mean grain yield (1657 kg ha -1 ) as<br />
compared to local variety (1227 kg ha -1 ). Improved varieties of<br />
upland rice, black gram, pigeonpea and mustard produced 40-50<br />
percent higher yields over local checks. The improved varieties<br />
of these crops were highly adopted by the farmers. About 80-<br />
90 percent adoption is recorded in case of Birsa Vikas Dhan-<br />
109 variety of rice, 60-70% adoption in case of Birsa urad-1 of<br />
black gram and 50-60% adoption in case of Birsa Arhar-1 of<br />
pigeonpea in Ranchi district.<br />
Pigeonpea + rice (1:3), pigeonpea + maize (1:1) and pigeonpea<br />
+ ground nut (1:2) gave pigeonpea equivalent yield of 749, 1233<br />
and 1587 kg ha -1 as against sole pigeonpea yields of 556, 491 and<br />
500 kg ha -1 with a B:C ratio of 0.81, 0.83 and 1.77 respectively.<br />
These systems are adopted by over 25 percent of farmers in the<br />
region. Intercropping of pigeonpea + okra (1:1) gives maximum<br />
pigeonpea equivalent yield of 2965 kg ha -1 with B:C ratio of<br />
4.10 as compared to sole pigeonpea yield of 2123 kg ha -1 with<br />
B:C ratio of 2.5 and sole okra yield of 900 kg ha -1 with BC ratio<br />
of 3.10. The system gives RWUE of 2.51 kg/ha-mm as against<br />
1.8 kg/ha-mm in sole pigeonpea and 1.97 kg ha -1 mm -1 in sole<br />
okra. There is an additional income of Rs.40000 ha -1 with this<br />
system as compared to sole crops.<br />
Labour savings through sowing behind plough was 42 man-hour<br />
per ha over sowing using Dutch hoe. However, higher mean<br />
yield was recorded in treatment of sowing by Dutch hoe (3084<br />
kg ha -1 ) as compared to behind plough (2560 kg ha -1 ). The use of<br />
Birsa ridger plough gives 20-30% higher yield advantage over<br />
traditional plough for major rainfed crops.<br />
Way forward<br />
About 80 percent area of the state of Jharkhand is rainfed<br />
and hence there is a need to give more emphasis on rainwater<br />
management. The declining annual rainfall and its erratic<br />
behavior, necessitates the needs for adoption of newer dryland<br />
farming technology. The watershed management is crucial for<br />
the development of the entire region.<br />
Focused research areas are:<br />
● Optimized use of natural resources, i.e. rainfall, land and<br />
water to minimize the soil and water loss and degradation of<br />
environment through soil and water conservation practices<br />
is essential.<br />
● The drought has become regular phenomenon in the region<br />
and therefore there is need to introduce drought resistant<br />
varieties for higher grain yield and fodder.<br />
● The alternate land use systems such as agroforestry needs to<br />
be encouraged along with animal husbandry for generating<br />
additional income.<br />
● Crop diversification with pulses and oilseeds<br />
● Rainfed integrated farming systems models<br />
● Farm mechanization

Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Sub-centre was established in 1987 at Faizabad<br />
under N. D. University of Agriculture & Technology to develop<br />
location-specific dryland technologies for the dryland farmers in<br />
the Eastern Plain zone of Uttar Pradesh.<br />
Agro-climatic zone characteristics<br />
In general, climate in the zone is sub-humid. The south-west<br />
monsoon contributes 90%, north-east monsoon 8% and summer<br />
rains 2% of total annual average rainfall of 1001.7 mm which<br />
is received in approximate 47 rainy days. The historical rainfall<br />
data (30 years) indicated that 15% to 20% of deficient rainfall<br />
during south western monsoon. The onset of monsoon is in<br />
the third week of June and withdrawal is during fourth week<br />
of September. The mean annual minimum temperature varied<br />
from 2.8 o C to 27.9 o C while mean annual maximum temperature<br />
ranges from 13.5 o C to 43.6 o C. For the past fifteen years, the dry<br />
spell during crop season was experienced during September at<br />
grain setting and maturity stages of major rainfed crops.<br />
Major soil types: Silty loam, clay loam, sandy loam and silty<br />
clay loam<br />
Major rainfed crops: The major rainfed crops cultivated in the<br />
zone during kharif season are rice, pigeonpea, maize, blackgram,<br />
greengram, sorghum, sesame and during rabi are chickpea,<br />
mustard, lentil, linseed and barley.<br />

being at par with sowing of pigeonpea on ridges and paddy<br />
in furrows (1:2) recorded paddy yield equivalent of 5436 kg<br />
ha -1 . The maximum grain and straw yield of rice and total<br />
input and output energy and rain water use efficiency was<br />
recorded under 15 cm bund height.<br />
● Significantly higher grain yield of maize (4286 kg ha -1 ) and<br />
RWUE (9.51 kg ha -1 mm -1 ) was recorded with ridge-furrow<br />
planting followed by broad bed (90 cm) furrow planting<br />
(3886 kg ha -1 ).<br />
● Pearlmillet yield was significantly higher (2177 kg ha -1 ) with<br />
supplemental irrigation (25 mm) from harvested rainwater in<br />
farm pond<br />
Cropping systems<br />
● In an evaluation of pigeonpea based intercropping systems,<br />
pigeonpea equivalent yield (PEY) was maximum (2153 kg<br />
ha -1 ) with pigeonpea + blackgram (1:3) intercropping system<br />
with land equivalent ratio (LER) of 1.90 and higher RWUE<br />
(4.28 kg ha -1 mm -1 )<br />
● Pearlmillet equivalent yield was significantly higher (9300<br />
kg ha -1 ) with rice-chickpea cropping system followed by<br />
rice-lentil system (6932 kg ha -1 )<br />
● In an experiment on weed management in upland rice,<br />
application of bispyribac sodium @ 20 g a.i/ha + almix @ 4<br />
g a.i/ha at 20 DAS resulted in higher weed control efficiency<br />
(93.6%)<br />
Integrated nutrient management<br />
● Application of 100% recommended NPK i.e. 60 kg N + 40<br />
kg P 2<br />
O 5<br />
+ 30 kg K 2<br />
O/ha was superior for maize under maizechickpea<br />
system with the significantly higher maize yield of<br />
2006 kg ha -1 . However, significantly higher chickpea yield<br />
of 1188 kg ha -1 was attained by FYM @10 t/ha. Maximum<br />
maize equivalent yield of the system (6162 kg ha -1 ) was<br />
attained with application of FYM @ 10 t/ha.<br />
● In the tillage and nutrient management study for rice-lentil<br />
sequence, conventional tillage + 2 hand weedings at 20-40<br />
DAS together with 100% N through organic source was<br />
superior with a rice yield of 1746 kg ha -1 and lentil yield<br />
of 829 kg ha -1 in the season. Low tillage + 100% NPK<br />
35
(inorganic) was the 2 nd best with a yield of 1392 kg ha -1 of<br />
rice and 730 kg ha -1 of lentil.<br />

c. Crop, soil, water and nutrient management strategies<br />
during seasonal drought<br />
a. Early season drought<br />
●<br />
●<br />
●<br />
●<br />
●<br />
●<br />
After seeding of rice, if there is break of monsoon by 7 to10<br />
days and if seedling mortality is observed, take up resowing<br />
with the same variety. Gap filling in rice.<br />
Raise staggered rice nursery at 15 days interval in small<br />
areas at least two times drum seeding<br />
In maize and pigeonpea, adopt gap filling/thinning to<br />
maintain optimum plant population and ridge sowing.<br />
Intercropping of maize/sorghum/pearlmillet with long<br />
duration varieties of pigeonpea.<br />
Thinning of overaged rice seedlings for better establishment<br />
and optimum plant stand.<br />
Foliar spray of 2.5 kg urea + 2.5 kg potash to increase the<br />
drought tolerance<br />
b. Midseason drought<br />
●<br />
●<br />
●<br />
Thinning to maintain proper distance between the plants.<br />
Weeding to conserve the residual soil moisture and leaf<br />
mulching to conserve the soil moisture.<br />
Frequent interculture and earthing up in pigeonpea.
●<br />
●<br />
●<br />
●<br />
●<br />
Foliar spraying of 2% urea or 2% MoP to boost crop growth<br />
and increase the resistance to drought.<br />
In case of late transplanting of rice (beyond 20 th July)<br />
planting should be dense by increasing the number of<br />
seedlings/hill from 2-3 to 3-4.<br />
Mulching with straw/grass cover.<br />
Life saving irrigation in transplanted rice.<br />
Intercropping of greengram / blackgram / maize / sorghum<br />
/ pearlmillet with long duration varieties of pigeonpea<br />
c. Terminal drought<br />
●<br />
●<br />
Alternate management of irrigation should be ensured for<br />
provide life saving irrigation.<br />
Harvesting of intercrop at physiological maturity (maize,<br />
blackgram and greengram).<br />
Singh et al.<br />
●<br />
●<br />
●<br />
Harvesting of green cobs (maize) and sell in market and<br />
remaining portion will be used for fodder.<br />
In case of fallow land, sowing of toria (Type-9, PT303 and<br />
Ageti Rai) should be sown in first week of September while<br />
Bhawani variety can be sown in second week of September.<br />
Better pulverization should be made for conservation of soil<br />
moisture following by planking for sowing of early rabi<br />

Brief history<br />
The AICRPDA centre, Jagdalpur started in the year 2004-05 at<br />
S.G. College of Agriculture and Research Station, Bastar district,<br />
Chhattisgarh under Indira Gandhi Krishi Vishwavidyalaya.<br />
The domain districts of the AICRPDA centre, Jagdhalpur are<br />
located in Bastar Plateau Zone (NARP) in Chhattisgarh and in<br />
the agro ecological sub region (ICAR) 12.1 and in the Eastern<br />
plateau and hills agro climatic region (planning commission).<br />
The domain districts of Jagdalpur centre are Bastar, Narayanpur,<br />
Dantewada, Kondagaon, Bijapur, Sukma. Since inception of the<br />
centre, both on-station and on-farm research is being carried in<br />
various thematic areas. On-farm research has been focused on<br />
farming-situation-specific (Badi, Marhan, Tikra, Maal, Gabbar)<br />
technology generation.<br />
Agro-climatic zone characteristics<br />
Climate<br />
In general, the climate of the zone is sub-humid. The southwest<br />
monsoon contributes 81% while north-east monsoon<br />
8.0%, winter season 1.2% and summer 9.8% of the total annual<br />
average rainfall of 1444.8 mm (mean of 40 years data). The<br />
normal onset of monsoon is during second week of June while<br />
normal withdrawal is during second week of September. The<br />
historical rainfall data (of 10 years) indicated 11.6% excess<br />
of the average rainfall (from 41 years) during south-west<br />
monsoon and 10.73% more annually. The dry spells are being<br />
experienced at panicle initiation and reproductive stages of the<br />
crop i.e during the month of September most frequently in 40 th<br />
standard meteorological week followed by 39 th week. The mean<br />
maximum and minimum temperature in the zone are 30.9 and<br />
17.4 o C, respectively.<br />
Major soil types<br />
Major soil types are Entisols (Marhan), Alfisols (Tikra),<br />
Inceptisols (Maal), Vertisols (Gabhaar) with area coverage of<br />
23.3, 49.7, 14.6 and 12.4%, respectively in the region.<br />
Major rainfed crops<br />
The major rainfed crops cultivated in the zone during kharif<br />
are rice, maize, fingermillet, horsegram, blackgram, pigeonpea,<br />

Significant achievements<br />
Rain water management<br />
●<br />
●<br />
●<br />
In case of in-situ moisture conservation under upland<br />
situation, one feet sunken/raised bed produced higher<br />
grain yield (2440 kg ha -1 ) and RWUE (1.97 kg ha -1 mm -1 )<br />
compared to crops sown on ½ feet sunken and raised bed.<br />
In an assessment of moisture conservation for mango, U<br />
shaped pits found superior with a maximum plant height of<br />
159.29 cm and plant girth of 10.05 cm.<br />
After rice in rabi season, different vegetable crops were<br />
cultivated by application of supplemental irrigation from<br />
the harvested rainwater and maximum yield of <strong>37</strong>423 kg/ha<br />
were attained in bottle gourd followed by pumpkin<br />

(Marhan and Tikra) of Bastar plateau.<br />
Technologies upscaled in convergence with various<br />
programmes<br />
The technologies upscaled through various programmes are<br />
drought tolerant varieties, furrow opening technique at 2 m<br />
interval in direct seeded rice crop, mechanization of sowing<br />
and threshing by tractor operated machine, placing of FYM in<br />
rice row at the time of sowing for conservation soil moisture<br />
during short term drought at mid-way of growth stages, residual<br />
moisture utilization by growing field pea and chickpea after rice<br />
under midland and lowland situation of the region are some of<br />
technologies which have been gone. District wise contingency<br />
plans were also upscaled in the zone with the help of KVK and<br />
line departments, (agriculture, horticulture, fisheries, veterinary<br />
etc.)
Impact of dryland technologies<br />
Soil moisture conservation practices like U shaped pit found<br />
superior which could control 10% runoff. One feet sunken/<br />
raised bed produced 13% higher yield and recharged ground<br />
water due to sunken bed. In bunded midland and lowland<br />
situations, integration with fish farming produced 6% extra<br />
income to the farmers of Bastar. Utilization of harvested rain<br />
water increased 10% more yield than rainfed situation. The<br />
irrigation was supplied with sprinkler systems. For integrated<br />
nutrient management in groundnut-onion cropping system and<br />
direct seeded rice- field pea cropping system, recommended<br />
dose of fertilizers with micronutrient produced higher yield<br />
and increased soil fertility, agronomic efficiency and recovery<br />
efficiency etc. Under dryland conditions, line sowing with Nari<br />
plough reduced 10% operation cost and manage the crop easily<br />
than the broadcasting. Reduced tillage save the energy and<br />
produced optimum yield which was at par with conventional<br />
methods. Application of bispyrabac sodium herbicides as post<br />
emergence reduced 20% labour and 25 % cost of cultivation.<br />
Under marhan conditions, rice + pigeonpea (5:1) with<br />
transplanting of pigeonpea 40 days after sowing + sodium<br />
molybdate seed treatment @ 4 g/kg seed of pigeonpea gave<br />
maximum rice yield of 2186 kg/ha followed by rice + pigeonpea<br />
(5:1) line sowing + sodium molybdate seed treatment @ 4 g/<br />
kg seed to pigeonpea (2063 kg ha -1 ). However, the intercropped<br />
pigeonpea yield was highest (862 kg ha -1 ) with rice + pigeonpea<br />
(5:1) with transplanting of pigeonpea 40 DAS + pigeonpea seed<br />
treatment with sodium molybdate @ 4 g/kg and application of<br />
Thakur et al.<br />
lime@ 200 kg ha -1 for pigeonpea were successful. In rice based<br />
double cropping system under gabhar situation conventional<br />
tillage (2 pass of country plough and sowing of seed) for field pea<br />
recorded higher seed yield (1823 kg ha -1 ), net Pigeonpea + okra<br />
(1:1) Pigeonpea + cowpea (1:1) Pigeonpea + blackgram (1:1)<br />
Pigeonpea + maize (1:1) produced returns of Rs. 63812 ha -1 , B:C<br />
ratio of 3.48 and RWUE of 3.41 followed by relay cropping of<br />
field pea (Utera) (1234 kg ha -1 ). In the relay cropping of rice<br />
(MTU 1001)-chickpea (JG-11) under lowland farming situation,<br />
higher rice crop equivalent yield of 5569 kg ha -1 , net returns of<br />
Rs.68262 ha -1 , B:C ratio of 3.93 and RWUE of 4.14 kg ha -1 mm -1<br />
was recorded with rice-chickpea.<br />

Brief history of the Centre<br />
AICRPDA centre was established at Bhubaneswar in 1971-72<br />
under Odisha University of Agriculture and Technology and<br />
was operated at Bhubaneswar upto 1992-93. Then the Centre<br />
was shifted to Bhawanipatna in 1992 and to Phulbani in 1994.<br />
Presently, the Centre is functioning at Phulbani. This Centres has<br />
been conducting research on different theme areas to generate<br />
location-specific technologies.<br />
Agro-climatic zone characteristics<br />
The domain districts of the AICRPDA centre, Phulbani are<br />
located in North Eastern Ghat Zone (NARP) in Odisha and in<br />
the Garjat hills, Dandakaranya and Eastern Ghats hot moist subhumid<br />
eco-sub-region of Agro-ecological sub-region (ICAR)<br />
12.1 and in the East coast plain and Hill region of agroclimatic<br />
region (Planning Commission).<br />
The climate of the zone is sub-humid. Out of the total annual<br />
average rainfall of 1407 mm, south west monsoon contributes<br />
80%, post-monsoon 10% and summer rainfall 10%. The onset<br />
of the monsoon is during second week of June and normal<br />
withdrawal is during first week of October. The historical<br />
rainfall data (of 30 years) indicated that the deviation from the<br />
normal rainfall during south west monsoon was found to be 16%<br />
excess and 13% deficit of the average rainfall. The mean annual<br />
maximum temperature is <strong>37</strong> °C and mean annual minimum<br />
temperature is 10.4 °C. Hottest month is May and cold month<br />
is December.<br />

Dryland agriculture problems<br />
Crop production and soil management<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Soils have low water holding capacity, low in organic<br />
carbon and plant available nutrients (NPK)<br />
Prone to soil and water erosion<br />
Crops suffer due to erratic monsoon causing dry spells in<br />
crop cycles<br />
Low adoption level of farm mechanisation at farmers’ field<br />
due to non-availability of improved farm implements and<br />
reluctance to adopt because of higher cost and fragmented<br />
and small land holdings<br />
Predominantly monocropping system, slow rate of crop<br />
diversification and non-availability of a suitable IFS model<br />
based on existing practices<br />
Socio-economic<br />
●<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Small, fragmented and scattered holdings with fragile<br />
resource base of farmers<br />
Frequent failure of crops leads to uncertain production<br />
Low borrowing and investment capacity coupled with lack<br />
of subsidiary enterprises.<br />
Inadequate agri-inputs during cropping season and poor<br />
marketing infrastructure.<br />
Lack of vegetation cover in farm without any social fencing.<br />
Illiteracy and gender bias<br />
Significant achievements<br />
Rainwater management<br />
●<br />
●<br />
Soil cement (6:1) mortar of 8 cm thickness restricted the<br />
seepage loss and the seepage flow in the farm pond. The<br />
cost of the soil cement lining of the tank of 76 m 3 is nearly<br />
41% cheaper than the polythene lining of same tank. Hence<br />
soil-cement (6:1) lined tank is recommended.<br />
Excess runoff water arising due to heavy rainfall events can<br />
be saved in dug out and lined farm ponds and judiciously<br />
43
●<br />
●<br />
●<br />
utilized in continuous furrow method of irrigation.<br />
Continuous furrow irrigation exhibited 29.46%, 46.75%,<br />
57.79% and 28.20% higher REY over ‘no irrigation’ in<br />
radish, cauliflower, yambean and okra, respectively.<br />
Strip and intercropping of cereal crops with pulses/oilseeds<br />
are approved practices for breaking long slopes which<br />
prevent soil loss, reduce runoff and enhance productivity.<br />
Groundnut + pigeonpea (4:2) intercropping system also<br />
gave significantly the highest REY (49.96 q/ha), the lowest<br />
runoff (267.5 mm), the lowest soil loss (6.06 t/ha) which was<br />
42% and 51.6% lower than the cultivated and uncultivated<br />
fallow respectively and also lead to less runoff (19.78%) as<br />
compared to other sole crops.<br />
Application of organic mulch in the vegetable fields was<br />
found to be the best to arrest soil erosion, conserve soil<br />
moisture, intercept surface runoff and suppress weed<br />
growth.<br />
Ridge furrow system of planting was found to be good for<br />
efficient irrigation from harvested rainwater and organic<br />
mulching with dried Sal or Cassia leaves in tomato – radish<br />
sequence. The ridge furrow system with organic mulching<br />
resulted in highest tomato equivalent yield (15.41 t/ha) in<br />
the tomato-radish sequence.<br />
Crops and cropping system<br />
●<br />
●<br />
Intercropping of vegetables with rice in definite row<br />
proportion and optimum plant population resulted in higher<br />
equivalent yield and LER.<br />
Arhar + okra either in 2:2 or 2:1 row ratio provided optimum<br />
plant population of the crops and resulted in maximum<br />
yield of the system. The arhar + okra (2:1) and arhar + okra<br />
(2:2) in row proportions yielded the highest amongst all the<br />
arhar vegetable intercropping system and recorded LER of<br />
1.6 and B:C ratio of 2.5.<br />
● The INM practices viz. 50% CF + 50% N (FYM) and 50%<br />
CF + 50% N (Green leaf) in yam + maize intercropping<br />
system resulted in high productivity under rainfed upland<br />
region.<br />
●<br />
●<br />
Rice + cowpea and rice + rice bean resulted in higher<br />
equivalent yield and net income. Application of FYM @ 5<br />
t/ha + 50% RDF recorded highest equivalent yield among<br />
nutrient management methods. Fodder helps to meet the<br />
requirement of feeding the milch animals.<br />
Intercropping of maize + vegetable resulted in higher maize<br />
equivalent yield (MEY) and net income as compared to sole<br />
maize. Intercropping of maize + cowpea resulted in higher<br />
MEY followed by maize + bitter gourd and maize + runner<br />
bean intercropping system. Application of FYM @ 10 t/ha<br />
+ VC @ 2 t/ha as basal and spraying pot manure at 15 days<br />
interval for 4 times recorded higher yield in all the maize +<br />
vegetable intercropping system.<br />
Behera et al.<br />
44<br />
●<br />
Rainfed vegetables like cauliflower, cabbage, knolkhol,<br />
tomato can be taken as intercrops in pigeonpea with various<br />
proportions of combination to provide better economic<br />
returns and sustainability in production. Among all the<br />
intercropping system, pigeonpea + tomato followed by<br />
pigeonpea + cauliflower/radish were found to be the most<br />
profitable intercropping systems, hence recommended for<br />
farmers in rainfed upland.<br />
Nutrient management<br />
●<br />
●<br />
●<br />
●<br />
Lime @ 8 q/ha with P and K each @ 40 kg/ha should be<br />
applied in maize - horsegram cropping system for higher<br />
yield of the system.<br />
Application of 100% RDF (N:P 2<br />
O 5<br />
:K 2<br />
O:20:40:20 kg/ha)<br />
+ Ca (in the form of PMS @ 5 q/ha) + S (in the form of<br />
gypsum @ 30 kg S/ha) + B (in the form of Borax @ 12.5<br />
kg/ha) exhibited highest pod yield in groundnut under<br />
rainfed conditions.<br />
Application of chemical fertilizer and organic manure<br />
separately and in combination along with lime and biofertilizer<br />
resulted in increase of turmeric yield. Blackgram<br />
was grown after the turmeric cultivation on residual fertility<br />
of different nutrients applied previously.<br />
Greengram-toria cropping sequence can be taken in place of<br />
upland rice to overcome drought. However, the productivity<br />
of the system is low due to inadequate nutrient supply and<br />
the soil is acidic in nature in this area. The productivity of<br />
the system can be improved through liming and use of other<br />
organic sources of nutrients as FYM and green leaf along<br />
with P and K.<br />
Energy management<br />
●<br />
●<br />
Use of Phulbani dryland weeder saved almost 53 MD (Man<br />
days) in weeding 1.0 ha of upland crop as against 111 mandays<br />
in case of local weeder (Gadi) and also registered<br />
around 21 and 9% higher grain yield than that with manual<br />
weeding and weeding with local weeder (Gadi). It creates<br />
soil mulch and conserves moisture besides working as a<br />
crust-breaker and potato digger. The weeder eliminates<br />
weeds early in closely sown (15 cm) upland rice.<br />
Conventional tillage + two interculture and integrated<br />
nutrient management with both organic and inorganic<br />
sources such as 50% organic + 50% inorganic gives the<br />
maximum rice yield.<br />

programmes<br />
●<br />
●<br />
●<br />
●<br />
Lining of farm pond on all the four sides with soil cement<br />
(6:1) mortar of 8 cm thickness restricted the seepage loss and<br />
conserves excess runoff water from the field and the stored<br />
water could be utilized for raising high value vegetable<br />
crops, which ultimately can double the farm profit. This<br />
technology has been upscaled by the watershed and fishery<br />
departments of the state.<br />
Rainwater management technologies such as raising bund<br />
height of field bund, graded bunding, staggered trench<br />
has been taken up as land development programme under<br />
MGNREGS programme in Kandhmal District.<br />
Maize + cowpea (2:2) intercropping system is advised<br />
to farmers of this district as sole maize cultivation is<br />
comparatively less remunerative, vulnerable to hazards of<br />
nature and depletes soil nutrients. The technology has been<br />
picked up by the Agriculture Department and demonstrated<br />
in all the blocks of Kandhamal district.<br />
Rice + fodder intercropping system has been adopted by<br />
the farming community as they realized the importance of<br />
the green fodder for the cattle. More nos. of training and<br />
demonstration on these aspects need to be conducted for<br />
their awareness.<br />
● Intercropping of maize + arhar (2:1) and arhar + radish (2:2)<br />
adopted by state and district action plans<br />
●<br />
Intercrop like cowpea / greengram / blackgram are<br />
intercropped in mango / cashew orchard for first 3 years and<br />
turmeric/ginger in subsequent years to develop an ALUS
which has been included in NHM programme of Dept. of<br />
Horticulture.<br />
● Popularization of drought tolerant rice (Vandana,<br />
Sahabhagi, ZHU 11-26) varieties among farmers in the<br />

●<br />
Contingent crop plans in adopted village (Budhadani and<br />
Gunjidraga of Phulbani block) during dryspell motivated<br />
farmers of the adjoining villages to include these<br />
interventions in their crop plan.<br />
Maize + ridge gourd (2:1) intercropping systems have been<br />
adopted by the local maize growers. Local maize is grown in<br />
0.15 lakh ha and hybrid maize is grown in another 0.35 lakh<br />
ha in the domain area. Such technology is being up-scaled<br />
through the RKVY programme of the state department of<br />
agriculture.<br />
Organic manures rather than chemical fertilizers in<br />
turmeric is being prioritized by NGOs, state department of<br />
horticulture through large scale demonstrations in village<br />
levels.<br />
Mulching practice in maize-based intercropping systems<br />
is being popularized by RKVY and ATMA programme<br />
of the state department of agriculture. This technology has<br />
also been extended to the maize growing interior district of<br />
Odisha.<br />
Impact of technologies<br />
The AICRPDA, Phulbani centre conducted demonstrations<br />
and training programme for farmers to update their knowledge<br />
and skills in modern dryland technologies. The impact of<br />
different dryland technologies in the North Eastern Ghats Agroclimatic<br />
Zone of Odisha are given below. The Centre also<br />
conducted demonstrations on location specific technologies<br />
to establish its production potentials on the farmers’ fields.<br />
The Centre is working as resource and knowledge centre of<br />
dryland agricultural technology for supporting the farmers and<br />
line departments. The Centre also supported Agriculture and<br />
Horticulture Department of the district as technical expert for<br />
capacity building of functionaries and farmers. The Centre also<br />
acts as an integral part of different agricultural committees of<br />
district administration. Ridge furrow system and broad bed<br />
furrow system with organic mulching improved the water<br />
holding capacity of soil by 34% and equivalent yield by 58%.<br />
Water harvesting in farm pond and its utilization for vegetable<br />
crops increased the equivalent yield by 62%, economic benefit<br />
(net return, B:C ratio) by 35% and <strong>37</strong>% respectively. Maize +<br />
Cowpea, Maize + Pigeonpea, Pigeonpea + Radish resulted in 60-<br />
70% increase in equivalent yield by intercropping system than<br />
sole cropping. Green manuring with Dhanicha: Rice resulted in<br />
15% increased yield<br />
Way forward<br />
The following research and development programme of the<br />
centre need to be focused in future.<br />
●<br />
●<br />
●<br />
●<br />
●<br />
●<br />
●<br />
More focus should be given to rain water conservation and<br />
effective utilization of technologies in accordance with<br />
‘more crop per drop’.<br />
Farming system research to aim at doubling the farm<br />
income by identification and addition of supplementary and<br />
complimentary components to the existing set up.<br />
Preparation of situation specific crop wise contingent plan<br />
for dissemination, adoption and validation.<br />
Focus should be given on system research involving<br />
traditional crops. Emphasize on supporting technology to<br />
“Paramparagat Krishi” and Krishi Sinchai Yojana”.<br />
Block level contingent plan should be prepared in context<br />
of climate change.<br />
More research should be given on organic agriculture,<br />
drought coping, carbon sequestration as Kandhamal district<br />
has been declared to be the organic district of Odisha.<br />
Emphasis should be given to strengthen and popularize the<br />
RIFS model in the zone incorporating more components<br />
like seasonal flowers, perennial exotic fruit trees, piggery,<br />
duckery and improved fingerlings of fish on a cluster model.<br />

Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Centre at Varanasi was started in 1971 under<br />
Banaras Hindu University. The Centre represents Eastern plain<br />
and Vindhyan zone in eastern Uttar Pradesh (AESR 4.3/9.2).<br />
The domain districts in this zone are Varanasi, Chandauli, Sant<br />
Ravidas Nagar, Mirzapur and Sonbhadra.<br />
Agro-climatic zone characteristics<br />
The climate of the zone is semi-arid to sub-humid. Out of the total<br />
annual average rainfall of 1191 mm, the south-west monsoon<br />
contributes 80%, north-east monsoon 15% and summer rainfall<br />
5%. The normal onset of monsoon is during third week of June<br />
and the normal withdrawal is during fourth week of September.<br />
Erratic rainfall (high intensity short duration), undulating<br />
topography and presence of hard rocks provides opportunity<br />
of surface water storage. A good number of water bodies are<br />
present in the region from ancient time but capacity of such<br />
bodies has been reduced due to siltation. Limited ground water<br />
is available and quality of ground water is also inferior.<br />

Major rainfed crops<br />
The major rainfed crops cultivated in the zone during kharif are<br />
rice, pigeonpea, maize, pearlmillet, greengram and sesame and<br />
during rabi are lentil, linseed and chickpea.<br />
Dryland agriculture problems<br />
●<br />
●<br />
●<br />
Uncertain rainfall events make farming highly risk prone.<br />
Rainfall pattern (amount and distribution) during last<br />
10 years has been very erratic resulting in uncertainty in<br />
cultivation of rice which is the main crop of the region.<br />
Poor resource base and low risk bearing capacity of farmers.<br />
Labour scarcity during peak season.<br />
Significant achievements<br />
Rainwater management<br />
●<br />
●<br />
●<br />
Wide diameter well (percolation well) for Vindhyan region<br />
has been developed & found effective for enhancing<br />
productivity. Rice yield could be enhanced by 25% with<br />
one supplemental irrigation (5 cm) using harvested water<br />
in the event of dry spell of 8 to10 days coinciding with the<br />
reproductive phase. In the event of delayed onset (up to 3 rd<br />
week of July). Pearl millet was found to be an effective<br />
alternative to rice.<br />
Construction of earthen checks and pitching by local<br />
available material (stone pitching) in natural gullies/nalas<br />
stored about 25-30% of total rainfall as the runoff water<br />
of catchment. Due to seepage and percolation losses, about<br />
50% of stored water is lost and rest of the water is available<br />
up to starting of rabi season. Stored water may be used as<br />
life-saving irrigation for drought proofing of kharif crops<br />
or as pre-sowing irrigation / deficit irrigation for rabi<br />
chickpea/ mustard.<br />
Ridge-furrow planting of pigeonpea on (ridge) and rice<br />
(in furrow) respectively in uplands and medium lands<br />
gives additional yield of rice from pigeonpea field. Tractor<br />
operated ridger makes ridges of height of 30-40 cm at 60 cm<br />
spacing. The practice gave additional yield of rice of about<br />
10-12 q/ha. Pigeonpea crop is protected under high rainfall<br />
situations and 20% area of pigeonpea is under this practice.<br />
Nutrient management<br />
●<br />
In a trial on rice at Varanasi, application of 100% RDF<br />
along with 25 kg ZnSO 4<br />
and 10 kg Borax per ha confirmed<br />
its superiority over 100% RDF, giving higher rice yield.<br />
However, yield levels were very poor due to late sowing<br />
and succeeding drought.<br />
48
●<br />
In a long term study of 25 years on INM, application<br />
of organic manure either alone or in combination with<br />
inorganic sources resulted in higher yield of rice and higher<br />
rainfall use efficiency as compared to other treatments.<br />
Incorporation of only organic source (i.e., wheat straw<br />
initially 9 years and 100% FYM) significantly increased<br />
the organic carbon by 10.5% and 14.4% for 0-15 cm soil<br />
layer, respectively. Application of inorganic fertilizer alone<br />
at full or half of the recommended dose decreased organic<br />
carbon by 1.1 and 1.3% while combining organic material<br />
with inorganic resulted in 6.8-9% increase of organic<br />
carbon. A significant increase (36-56%) in the stability of<br />
the aggregates was observed under organic alone and / or<br />
with inorganic nutrient while a decrease in stability was<br />
observed under only inorganic nutrient supplementation.<br />
The bulk density, moisture retention capacity, infiltration<br />
rate and CEC were also significantly improved under<br />
organic alone or / and with inorganic combination as<br />
compared to inorganic nutrient alone.<br />
Crops and cropping systems<br />
●<br />
Pigeonpea (75 cm) + one row of okra was found more<br />
productive and remunerative than sole system on typical<br />
uplands. Planting one row sesame (T12 / GT1) between<br />
2 paired rows of pigeonpea (30+90 cm) resulted in higher<br />
productivity (230 kg/ha) and monetary advantage (B:C<br />
ratio of 3.5).<br />
● Planting linseed + mustard with row ratio 4:2 / 6:2<br />
intercropping resulted in 72% yield and 0.28 to 0.31 SYI.<br />
●<br />
Malviya vishwanath (HUL 57), moderately drought and<br />
wilt tolerant lentil variety developed by Varanasi centre<br />
produced 1400 kg ha -1 which was 25% higher than existing<br />
varieties (PL406 & PL 439) with a B:C ratio of 3.46.<br />

Impact of technologies<br />
Summer tillage helped in greater retention of rainwater (36 per<br />
cent higher over conventional method) and reduces 68 per cent of<br />
total runoff as against 50% of runoff water with farmer’s practice.<br />
This practice enhances the yield of rice (NDR-97) to 2620 kg/<br />
ha, pigeonpea (Bahar I MA-13) to 1080 kg/ha and sesame (Pant<br />
4) to 290 kg/ ha against 2280 kg/ha rice, 580 kg/ha pigeonpea<br />
and 210 kg/ha sesame with conventional tillage. Ridge- furrow<br />
planting helped in runoff modulation, crop diversification, soil<br />
fertility built up, risk reduction and disruption of pest cycle.<br />
This system produces a rice equivalent yield of 8866 kg/ha<br />
(2200 kg/ha of rice and 2000 kg/ha of pigeonpea) as against<br />
3500 kg/ha of rice with farmers’ practice of sole rice under flat<br />
planting. Planting of pearl millet and maize results in increased<br />
grain yield by <strong>37</strong> and 73%, respectively as farmers’ practice of<br />
broadcasting. Pearl millet and maize is grown on 5% area of<br />
this region particularly by progressive farmers, by adopting this<br />
technology in 50,000 ha, there would be an income benefit to<br />
the farmers to about Rs.26.8 crores and Rs. 28 crores, by pearl<br />
millet and maize cultivation. Malaviya Vishwanath (HUL-57)<br />
gives seed yield of 1400 kg /ha, which is 85 per cent more than<br />
the existing local variety (755 kg/ha). HUL-57 showed highest<br />
sustainable yield index of 0.42 compared to 0.35 and 0.38 of<br />
PL406 and PL639 respectively. It performs well in farmers’<br />
fields also. By replacing of wheat (860 kg/ha) by chickpea (2850<br />
kg/ha) or lentil (1620 kg/ha) farmer can realize a rice equivalent<br />
yield of 13127 kg/ha and 7629 kg/ha respectively with ricechickpea<br />
system and rice-lentil system with corresponding net<br />
returns of Rs.72197 and Rs.33400/ha and with B:C ratio of 4<br />
and 1.9 respectively. This is against rice equivalent yield of<br />
4230 kg/ha and net returns of Rs.9600/ha with farmer’s practice<br />
of rice-wheat system. Intercropping of pigeonpea (Bahar) and<br />
sesame (Type 4) (30/90 cm) gave 85 per cent higher productivity<br />
over farmers’ practice of sole pigeonpea cropping or pigeonpea<br />
mixed cropping. This system produces 1180 kg/ha of pigeonpea<br />
equivalent.<br />
Way forward<br />
Future dryland agriculture research focus would be on<br />
developing rainwater management, rainfed integrated farming<br />
systems modules, crop diversification/intensification, strip<br />
cropping systems, soil quality, agroforestry systems and farm<br />
mechanization.

Brief history of the centre<br />
A dry farming research centre was started at Bijapur in 1933.<br />
Later on, a sub centre of All India Coordinated Research<br />
Project for Dryland Agriculture was started at Bijapur in 1970.<br />
Subsequently the Sub-centre was upgraded as Main centre in<br />
1984. This centre was under University of Agricultural Sciences,<br />
Bangalore up to 30 th September 1986 and from 01-10-1986<br />
repatriated to University of Agricultural Sciences, Dharwad.<br />
Presently, the centre is located at Regional Agricultural Research<br />
Station, Vijayapura (earlier Bijapur) in Karnataka.<br />
Agro-climatic zone characteristics<br />
The agroclimatic zone of the centre is the Northern Dry zone<br />
(Zone-3) of Karnataka. This zone covers an area of 4.78<br />
million ha of Vijayapura, Bagalkote, Gadag, Bellary, Koppal,<br />
parts of Dharwad, Belagavi and Raichur. Northern Dryzone of<br />
Karnataka (Zone-3) and it comprises five Agro-ecological sub<br />
regions such as; Hot Arid ESR (24, 28 200 ha), 6.1 Hot dry<br />
semi-arid ESR (13, 88 408ha), 6.2 Hot moist Semi-arid ESR<br />
(60,000 ha), 6.4 Hot dry sub-humid ESR (9,12,000 ha) and 7.1<br />
Hot dry Semi-arid ESR (64, 200 ha). The climate in this zone is<br />
dry semi-arid. Out of the total annual average rainfall of 594.4<br />
mm with 38 rainy days, the South-West monsoon contributes<br />
65%, while 22.5% and 12.5% is from North-East monsoon<br />
and summer, respectively. The normal onset of South-West<br />
monsoon is during the first week of June and normal withdrawal<br />
is during the first week of September. Maximum normal air<br />
temperature ranging from 38.6 to 39.15 °C was noticed in April<br />
and May. The mean monthly minimum temperature of 14.55°C<br />
was noticed in January. Higher wind speed was observed in<br />
June and July and less wind speed in November. The relative<br />
humidity during the period fluctuated between 31.1% in March<br />
to 69.9% during August.<br />
Major soil types<br />
The major soil types in the zone are shallow to very shallow<br />
black soils (43%), medium deep to deep black soils (<strong>37</strong>%) and<br />
fine red clay loam/ red and black mixed soils (20%).<br />

Dryland agriculture problems<br />
Crop production related constraints<br />
●<br />
●<br />
●<br />
Inadequate, low and erratic rainfall, most vulnerable and<br />
aberrant weather condition, undulating topography and<br />
rolling plains and lowering of groundwater table<br />
Low adoption of rainwater management techniques with<br />
special reference to moisture conservation practices and<br />
low adoptability of farm ponds at farmer’s level<br />
Soils are highly degraded with low water retention capacity,<br />
multiple nutrient deficiencies and low organic content (0.35<br />
to 0.50%), very low or negligible use of organic manures,<br />
risk of crop failure, monocropping and low yielding crop<br />
varieties<br />
Infrastructure and institutional constraints<br />
●<br />
●<br />
Physical constraints of transportation which link the farmers<br />
with different profiles of market and also facilities of cold<br />
storage and power are existing<br />
Fragmentations of small holdings have constraints for<br />
efficient use of land, family labour and cannot reap scale<br />
economics<br />
51
Socio-economic constraints<br />
●<br />
●<br />
●<br />
Migration of agricultural labourers<br />
Small and marginal farmers do not have the ability to invest<br />
in agriculture and allied sectors requiring high capital and<br />
labour inputs<br />
Market risks<br />
Research initiatives/focus since inception of the centre<br />
To address the above constraints, various research programmes<br />
were formulated and submitted to the different externally<br />
funding agencies for the funding and implemented the same on<br />
station and on farm.<br />
NWDPRA - Operational Research Project: During the year<br />
1993, under the National Watershed Development Programme<br />
for the Rainfed Agriculture (NWDPRA), the University<br />
of Agricultural Sciences, Dharwad had been assigned the<br />
responsibility of conducting the adoptive research on rainwater<br />
conservation and sustainable agricultural production system. In<br />
turn, the University assigned a major part of this activity to the<br />
dryland Centre, Vijayapura. This project was operational from<br />
1993-2003 (10 years). Under the project, eleven model micro<br />
watersheds one micro watershed in each of the districts on a<br />
holistic approach in Northern Karnataka have been developed.<br />
National Innovations on Climate Resilient Agriculture<br />
(N<strong>ICRA</strong>): Since 2011, the N<strong>ICRA</strong> project has been operated at<br />
Vijayapura centre. The village, Kavalagi has been selected for<br />
the study. The centre initiated the both on station and on farm<br />
research/demonstrations on real–time contingency measures.<br />
The contingency measures includes both addressing the real<br />
time issues as well as the preparedness.<br />
Advanced research and upscaling of dryland technologies<br />
in Northern Dry zone of Karnataka (DARE-GoI): Under the<br />
DARE, GoI, SFC funded project, during 2013-15, three villages<br />
Honwad, Hansbhavi and Hullur villages were selected from the<br />
Vijayapura, Bagalakote and Gadag districts respectively. SWC<br />
structures (bunds, farm ponds) were constructed in 1,000 ha<br />
area of project villages and also other dry land practices were<br />
demonstrated. About 15-20% increase in yield was observed in<br />
treated areas over the conventional practices.<br />
CGIAR-DS Upscaling of focused dryland technologies<br />
through participatory mode: UASD and ICRISAT<br />
collaborative research project CRP-DS (CGIAR Research<br />
Program on dryland systems) was operated under AICRPDA<br />
(UAS Dharwad, Karnataka) at Vijayapura center from 2014-<br />
2016 (two years) with the main objective of transferring dryland<br />
technologies to the farmers for climate-resilient agriculture. In<br />
this project, three villages viz., Nandihal, Manur and Balaganur<br />
of Vijayapura dist. were selected for conducting demonstrations,<br />
research activities and capacity building.<br />
Shirahatti et al.<br />
CGWB - Rainwater harvesting and ground water recharge<br />
in Vijayapura campus: The CGWB funded project was<br />
implemented during 2012-14 at RARS, Vijayapura campus.<br />
The economics of the project revealed that the cost of rooftop<br />
rainwater harvesting works out to be Rs. 19.20 per 1000 litres<br />
of water. The cost of water harvesting through the artificial<br />
recharge structure is about Rs. 3.64 per 1000 litres of water. The<br />
weighted average of the unit cost of water harvesting of all the<br />
structures would be Rs. 4.35 per 1000 litres.<br />
IWMP - Installation of silt monitoring stations for runoff<br />
and sediment studies: The University of Agricultural Sciences,<br />
Dharwad collaborated with the watershed development<br />
department from 2011-2014 in establishing and monitoring silt<br />
monitoring stations (SMS) at the selected micro watersheds<br />
in the districts of Vijayapura, Bagalakote, Gadag, Dharwad,<br />
Belagavi, and Uttara Kannada. These districts fall in three agroclimatic<br />
zones viz., northern dry zone, hilly zone, and northern<br />
transition zone. The benchmark information (pre-treatment)<br />
on runoff, soil loss and nutrient loss were monitored. Further,<br />
change in the runoff, soil loss and nutrient losses after the<br />
imposition of the soil and water conservation measures in the<br />
watershed were also monitored.<br />
Significant achievements/findings<br />
Rainwater management<br />
●<br />
●<br />
●<br />
●<br />
Impact evaluation of inorganic mulches on the major crops<br />
of this region indicated that in the mulched plots, additional<br />
yield advantage of 11.28-62.8 percent was recorded over the<br />
control, while the average reductions in the runoff and soil<br />
loss over the control were 31 and 52 percent respectively.<br />
In set-furrow cultivation, pigeonpea equivalent yield was<br />
significantly higher in set furrow with residue + glyricidia<br />
incorporation (1409 Rs. ha -1 ). But it was on par with set<br />
furrow with silt + residue + glyricidia incorporation (1349<br />
Rs. ha -1 ).<br />
Compartmental bunds help in conserving soil moisture<br />
and the rainwater is conserved in the bunds where it falls<br />
as the bunds provide more opportunity time for water to<br />
infiltrate into the soil. Adoption of compartmental bunding<br />
in rabi sorghum, sunflower, safflower and chickpea gave<br />
yield advantages of 40, 35, 38 and 50%, respectively over<br />
no compartmental bunding or flat planting.<br />
Wider row spacing with frequent deep inter-cultivation<br />
with blade harrow increased the yield of pearl millet to 500<br />
kg ha -1 as against 250 kg ha -1 with farmers practice. The<br />
effectiveness of this technology was more observed during<br />
sub normal rainfall years. Response of rabi sorghum with<br />
recommended practices to contour key line cultivation in<br />
shallow black soil was conducted at Vijayapura centre.<br />
52
●<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Sowing of rabi sorghum along the contour key line with<br />
60 cm row spacing and recommended dose of fertilizer<br />
gave a higher yield of 8.0 q ha -1 compared to 5.0 q ha -1 when<br />
sowing was done along the slope as per farmer’s practice.<br />
Double cropping was made possible due to this Zingg<br />
Conservation bench terraces in the farmers’ fields. The<br />
extent of increase in the yield of different crops ranged<br />
between 30 to 60%.<br />
Studies on vegetative and mechanical checks for soil and<br />
moisture conservation revealed that the runoff reduction<br />
due to the vegetative and mechanical checks as against the<br />
control plot was in the range of 20.2 % to 47.8%.<br />
Sub soiling (chisel plough) is one of the cheap and effective<br />
in-situ moisture conservation measures. From the three<br />
years study, it is concluded that the subsoiling at 2 m spacing<br />
with vermicompost application @ 2.5 t ha -1 has recorded the<br />
higher yield of 25.3%. The higher yield is attributed to the<br />
sub soiling, which helped higher infiltration of rainwater<br />
into the soil.<br />
Pebble mulch recorded lower runoff (11 ha cm) compared<br />
to conventional practice (38 ha cm), resulting in a lesser<br />
quantity of soil loss of 0.78 t ha -1 as against 4.51 t ha -1 ,<br />
and produced greater wetting front depth. Further, it gave<br />
a higher sorghum grain equivalent yield of 24.5 q ha -1<br />
compared to 16.5 q ha -1 with conventional practice.<br />
The surplus water calculation under GIS environment<br />
showed that the annual runoff as the percentage rainfall was<br />
14.38 percent (81.6 mm).The analysis of rainfall intensity<br />
of eight rain gauge stations of 11 years (2001 to 2011)<br />
period revealed that most of the time i.e., six out of ten<br />
times the maximum rainfall intensity was occurred during<br />
September followed by May and October, hence chances<br />
of filling up of the rain water harvesting structures are very<br />
high during these months. Based on rainfall, topography of<br />
the land, soil type and land use pattern, a farm pond of 150<br />
m 3 size is sufficient for each hectare of catchment area in<br />
black soils with provision of emptying it after its fill-up to<br />
accommodate the subsequent events of runoff. Farm pond<br />
water balance revealed that 625.7 m 3 (27.3%) of water was<br />
lost in the form of evaporation from June to January, 200<br />
m 3 (8.6%) water was lost in the form of seepage and about<br />
6 per cent water was left in the pond as the dead storage,<br />
resulting in the remaining 1328 m 3 (58 %) of water for<br />
use. The evaporation of water was quantified during 2016<br />
and 2017. During this period, it was observed that least<br />
evaporation was recorded in steryl alcohol (106.9 cm)<br />
followed by silicon oil (107.5cm). The highest evaporation<br />
was observed in control (181.07 cm). This water could be<br />
●<br />
●<br />
beneficially used by providing one supplementary irrigation<br />
of 50 mm to obtain additional yield of 39.7% in sorghum<br />
and 29.2% in chickpea.<br />
Groundwater recharge by diverting nala water through a<br />
horizontal filter to an open well indicated the possibility<br />
of harvesting annually 4.14 lakh litres of the runoff water.<br />
The hydro geologically nine significant different thematic<br />
layers viz., geology, soil, land use/cover, water table<br />
fluctuation, depth to bed rock, slope, drainage density,<br />
lineament density and geomorphology were used as the<br />
input and multi criteria evaluation (MCE) for finalizing/<br />
recharge suitability sites for the upper Don river basin.<br />
For arresting the silt in ground water recharge, the vertical<br />
filter performed better than the horizontal filter. Further,<br />
wherever only sand is available, then 60 cm thick sand<br />
filter may be used, it works with the 78 per cent efficiency.<br />
Further, where all the three layers (sand + medium jelly +<br />
small boulder) are available then filter with the nylon mesh<br />
should be used. With this, the highest filter efficiency of<br />
94 percent could be achieved. The impact analysis of SWC<br />
works on groundwater recharge revealed that the shallow<br />
water table was recorded during October, while the deep<br />
was recorded during June, further the average ground water<br />
recharge recorded was 9.9 - 11.5 percent of annual rainfall,<br />
similar recharge results were reported by National Institute<br />
of Hydrology. Further, the SWC structures were effective<br />
for recharging, only when annual rainfall was normal or<br />
above normal. The impact of RWH structures on depth<br />
to the water table, water yield and water quality of seven<br />
observation bore wells, which are falling in the vicinity of<br />
the RWH structures were selected. The year 2012-2013<br />
was treated as pre-treatment year and the years 2013-<br />
14 and 2014-2015 were treated as post-treatment years.<br />
The outcomes of the monitoring of the observation wells<br />
revealed that there was the trend of increase in the water<br />
table and the well yield.<br />
The crop management factor ‘C’ values for USLE soil loss<br />
assessment model were determined as 0.5 for kharif, 0.7 for<br />
rabi, and 0.3 for the bi-seasonal crops. Established the silt<br />
monitoring stations (SMS) at the selected micro watersheds<br />
in the districts of Vijayapura, Bagalakote, Gadag, Dharwad,<br />
Belagavi, and Uttara Kannada. The benchmark information<br />
(pre-treatment) on runoff, soil loss, and nutrient losses<br />
were monitored. Further, change in the runoff, soil loss<br />
and nutrient losses after the imposition of the soil and<br />
water conservation measures in the watershed were also<br />
monitored.<br />

Crops and cropping systems<br />
● Residue incorporation alone and residue incorporation +<br />
tied ridging gave significantly higher yield of pigeonpea,<br />
rabi sorghum and chickpea as compared to control.<br />
This is attributed to higher available moisture content<br />
and conspicuous increase in the physical and biological<br />
properties of the soil. For sustained higher yield there<br />
is no need to apply nitrogen to rabi sorghum + chickpea<br />
intercropping system in the yearly rotational cropping<br />
system of pigeonpea-sunhemp - rabi sorghum + chickpea<br />
(2:1) if crop residues (only leaf litter plus roots of<br />
pigeonpea) are incorporated continuously. Tied ridging<br />
is an additional advantage especially during low rainfall<br />
years. In another study to determine the best genotype with<br />
the land configuration for exploiting higher yield potential<br />
of pigeonpea under rainfed condition, the pigeonpea<br />
GRG-152 produced higher seed yield than TS-3R. In land<br />
configuration treatments, planting pigeonpea on broad bed<br />
furrow recorded higher yield over flatbed.<br />
●<br />
●<br />
●<br />
Intercropping of castor + sunflower in the row ratio of<br />
2:4 or 1:1 gave significantly higher net returns compared<br />
to sole crops and other intercropping systems. Net returns<br />
of Rs. 14731 ha -1 in castor + sunflower (2:4), Rs. 55<strong>37</strong>8<br />
per ha with incorporation of crop residue and 1 t ha -1 of<br />
poultry in chilli + onion (2:4) were found significantly<br />
superior compared to traditional cropping systems. Rabi<br />
sorghum grain equivalent yield in rabi sorghum + chickpea<br />
intercropping system was significantly higher when it was<br />
followed by kharif sunflower with 135 cm x 30 cm planting<br />
geometry.<br />
Among different ITK cropping systems which are rotated<br />
with pigeonpea + greengram (2:4), onion relayed with<br />
rabi sorghum rotated with pigeonpea + greengram (2:4)<br />
produced significantly higher pigeonpea equivalent yield<br />
(<strong>37</strong>51 kg ha -1 ), gross returns (Rs. 77670 ha -1 ) and net<br />
returns (Rs. 52961 ha -1 ). In chilli + onion (2:4), spraying of<br />
cow-pat pit manure (5g/litre), (Rs. 33433 ha -1 ) bio-digestor<br />
(Rs. 31258 ha -1 ) and vermiwash (1:5), (Rs. 30434) spray<br />
found to record significantly higher net returns. Studies<br />
on alternate cropping systems and new crop introductions<br />
in medium to deep black soil shows that, Chilli + Onion<br />
(2:4) cropping system with poultry manure application (2 t<br />
ha -1 ) incorporation of crop residue resulted in significantly<br />
higher net returns compared to other cropping systems.<br />
Among production systems followed by different farmers,<br />
cucumber–sunflower production system gave the highest<br />
B:C ratio followed by the cucumber – rabi sorghum. These<br />
practices during kharif provide substantial income to the<br />
rainfed farmers besides reducing the rain drop impact on<br />
the soil and conserving the rainwater in-situ. Growing of<br />
Shirahatti et al.<br />

●<br />
●<br />
●<br />
cucumber, ridgegourd, bittergourd during kharif ensured<br />
substantial additional income to the farmers and efficient<br />
in-situ rain water harvesting.<br />
Growing of Bt. Cotton at 120 cm x 45 cm with application<br />
of 60:30:60 kg NPK per ha produced significantly higher<br />
kapas yield, gross returns and net returns (1433 kg ha -1 ,<br />
Rs. 70,0<strong>37</strong> ha -1 , Rs. 46115 ha -1 ). In onion, crop geometry<br />
of 45 cm x 10 cm with application of 62.5:25:62.5 kg N,<br />
P 2<br />
O 5<br />
, K 2<br />
O per ha gave significantly higher bulb yield of<br />
7930 kg per ha. Moth bean genotype MBS-27 spaced at 45<br />
cm x 10 cm with application of vermicompost @ 1 t ha -1<br />
produced higher seed yield, gross returns and net returns.<br />
Chickpea variety GBM-2 and JG 11 at 45 cm x 10 cm gave<br />
significantly higher seed yield. Similarly black gram at crop<br />
geometry of 45 cm x 10 cm with application of 15:<strong>37</strong>.5 kg<br />
N, P2O5 per ha gave significantly higher grain yield of 595<br />
kg per ha. Clusterbean (gum gaur) sown at crop geometry<br />
of 30 cm x 10 cm gave significantly higher grain yield of<br />
408 kg per ha as compared to 45 cm x 15 cm (361 kg ha -1 ),<br />
45 cm x 20 cm (293 kg ha -1 ), 60 cm x 10 cm (275 kg ha -1 )<br />
and 60 cm x 20 cm (229 kg ha -1 ). But it was on par with 45<br />
cm x 10 cm (401 kg ha -1 ). Response of mustard genotypes<br />
to dates of sowing under supplemental irrigation indicated<br />
that, sowing of mustard variety SEJ-2 during Sept II<br />
fortnight with two protective irrigations gave significantly<br />
higher yield compared to other varieties. Sowing of mustard<br />
(SEJ-2) during Sept II fortnight is best suited for this area<br />
under supplemental irrigation.<br />
There was no significant difference in the grain and<br />
fodder yield of rabi sorghum due to hydrogel. Studies<br />
on drought proofing technologies in rabi sorghum and<br />
chickpea revealed that, in rabi sorghum the grain yield<br />
was significantly higher with seed treatment of cow urine<br />
for 8 hours whereas seed soaking in water, cow urine,<br />
panchaganga for 8 hours and seed treatment with KH 2<br />
PO 4<br />
gave significantly higher seed yield of chickpea compared<br />
to control. Seed treatment with cow urine for 8 hours in<br />
sorghum and soaking of chickpea seeds in water are the<br />
promising cheaper non cash techniques of drought proofing.<br />
In real-time monitoring and management of agricultural<br />
drought in pigeonpea indicated that the treatment, including<br />
real-time contingency plan interventions during early, midseason,<br />
and terminal drought, recorded 11.83% higher yield<br />
and 14.34% higher net returns than farmers’ practice (no<br />
interventions) treatment.<br />
In contingent crop planning, the performance of different<br />
cropping systems in different ‘Nakshatras’ were studied<br />
and the suitable cropping systems to different nakshatras at<br />
different soil types were developed.
●<br />
Based on the soil conservation unit (SCU) and soil quality<br />
units (SQU), the land management units (LMU) have<br />
been derived at Kavalagi watershed area. There is a total<br />
of 14 LMUs. However, for the study, four LMU (I, III,<br />
V and VII) have been considered. The study was planned<br />
to observe the effects of NPK fertilizer on growth, yield<br />
and quality of chickpea under different land management<br />
units (LMU’s). The LMU 1 has given significantly higher<br />
seed yield of chickpea as compared to LMU 3, LMU5, and<br />
LMU7. Among the nutrient management, the application<br />
of <strong>37</strong>.5:75:0 NPK kg ha -1 has produced significantly higher<br />
seed yield of chickpea as compared to the application of<br />
25:50:0 NPK kg ha -1 and farmers’ practice (25:35:0 NPK kg<br />
ha -1 ). Among the interactions, LMU 1 with the application<br />
of <strong>37</strong>.5:75:0 NPK kg ha -1 has produced significantly<br />
higher chickpea seed yield as compared to other treatment<br />
combinations, but it was on par with LMU 3 with the<br />
application of <strong>37</strong>.5:75:0 NPK kg ha -1 .<br />
Nutrient management<br />
●<br />
In permanent manurial trial on safflower - rabi sorghum<br />
rotation (1986-87 to 2007-08), the pooled data on seed yield<br />
of sunflower indicated that incorporation of sunhemp at 45<br />
DAS increased the seed yield of sunflower significantly (716<br />
kg ha -1 ) compared to conventional practice (554 kg ha -1 ). A<br />
permanent manurial trial on yearly rotation of rabi sorghum<br />
+ chickpea (2:4) and safflower + chickpea (2:4) (2017-18 to<br />
onwards) indicated that application of 50% N through FYM<br />
+ 50% N through inorganic sources recorded significantly<br />
higher sorghum equivalent yield and safflower equivalent<br />
yield as well as B:C ratio in rabi sorghum + chickpea (2:4)<br />
and safflower + chickpea (2:4) intercropping system. Low<br />
till farming strategies for resource conservation and soil<br />
quality for sorghum-sunflower yearly rotational system<br />
(2000-01 to onwards) showed higher grain yield of rabi<br />
sorghum (1398.5 kg ha -1 ) was obtained with low till (LT2):<br />
1 harrowing + 1 hoeing + weedicide and statistically on<br />
par with low till (LT1): 2 harrowing + 1 hoeing + 1 hand<br />
weeding and conventional tillage (CT). Among the nutrient<br />
management practices, the higher grain yield and monetary<br />
net returns were recorded in sunhemp incorporation @<br />
2.5 t ha -1 + 50% RDF through fertilizer. Effect on soil<br />
productivity by application and utilization of distillery byproducts<br />
as organic manures in dryland regions of northern<br />
Karnataka (2020-21 to onwards) indicated highest grain<br />
yield (1830.3 kg ha -1 ) and B:C ratio (3.9) was observed when<br />
spent wash at 5 ml kg -1 of soil (1:10 spentwash and water<br />
dilution) applied in conjunction with recommended dose of<br />
NP fertilizers and the same on par with the application of<br />
spentwash at 5 ml kg -1 of soil (1:10 spentwash and water<br />
dilution) alone.<br />

●<br />
Integrated nutrient management in sunflower – rabi<br />
sorghum cropping system in medium deep black soils<br />
(1998-99 to 2002-03) showed that sunflower seed yield<br />
revealed that incorporation of sunhemp at 45 DAS increased<br />
the seed yield of sunflower significantly (1476 kg ha -1 ) as<br />
compared to farmer’s practice (882 kg ha -1 ) and retention of<br />
stubbles on soil surface (1180 kg ha -1 ), but it was on par with<br />
application of FYM @ 5t ha -1 (1333 kg ha -1 ). The pooled<br />
data of grain yield of rabi sorghum revealed that application<br />
of FYM @ 5t ha -1 gave significantly higher grain yield of<br />
1643 kg per ha as compared to farmer’s practice (1143 kg<br />
ha -1 ). Integrated nutrient supply system for rainfed semiarid<br />
tropics-cereals (1998-99 to 2006-07) indicated that<br />
application of 15 kg N through compost + 20 kg N through<br />
fertilizer recorded significantly higher sorghum grain yield<br />
followed by 15 kg N through sunnhemp + 20 kg N through<br />
fertilizer. Integrated nutrient supply system for rainfed<br />
semi-arid tropics – legume (1998-99 to 2006-07) showed<br />
that the grain yield of rabi sorghum was significantly higher<br />
with supply of 15 kg N through sunnhemp/compost + 20 kg<br />
N through fertilizer which was comparable with application<br />
of 15 kg N through sunnhemp/compost + 10 kg N through<br />
fertilizer. Similarly, integrated nutrient supply system for<br />
rainfed semi-arid tropics: cereal + legume (1998-99 to<br />
2006-07) proved that the grain yield of rabi sorghum was<br />
significantly higher with application of 15 kg N through<br />
sunnhemp/compost + 20 kg N through fertilizer and that<br />
of chickpea with supply of 15 kg N through sunnhemp/<br />
compost + 20 kg N through fertilizer which was comparable<br />
with application of 15 kg N through sunnhemp/compost +<br />
10 kg N through fertilizer. The response of sunflower to<br />
the applied potassium (2006-07 to 2007-08) showed the<br />
yield of crops were significantly higher with application<br />
RDF in conjunction plus organics (RD FYM) as compared<br />
to rest of the treatment. In Rainfed area network project on<br />
balanced nutrition in rabi sorghum (2007-08 to 2014-15),<br />
the highest grain yield of rabi sorghum was reported with<br />
recommended dose of fertilizer plus Zn (10 Kg ha -1 ) plus Fe<br />
(50 Kg ha -1 ) (1778 kg ha -1 ) as compared to other treatments.<br />
The lowest yield was recorded in control (No manure/ No<br />
fertilizer) (1107 kg ha -1 ). The response of chickpea and<br />
rabi sorghum to zinc and iron nutrition (2015-16 to 2016-<br />
17) reported significant increase in the yield of chickpea<br />
and rabi sorghum with the application of RDF with 10 kg<br />
each of Ferrous sulphate (FeSO 4.<br />
7H 2<br />
O) and Zinc Sulphate<br />
(ZnSO 4<br />
.7H 2<br />
O). Studies on foliar spray of nutrients on<br />
growth and yield of rabi sorghum (2015-16 to 2016-17)<br />
indicated that the yield of rabi sorghum was higher in foliar<br />
spray with potassium nitrate (0.5%) at 30 and 60 DAS.
Energy management<br />
●<br />
Sowing of sunflower with ridger-seed-fertilizer drill<br />
produced 22-57 per cent higher yield than sowing with<br />
tractor drawn seed drill. While sowing of rabi sorghum<br />
with bullock drawn seed drill gave 43 per cent higher yield<br />
than ridger - fertilizer - seed drill. In situ incorporation<br />
of sunhemp (5 t ha -1 ) at 45-50 DAS with farmers method<br />
of nutrition under conventional tillage was found to be<br />
significantly superior for both rabi sorghum and sunflower<br />
in yearly rotation cropping system. Among the different<br />
automatic seed drills, CRIDA bullock drawn automatic<br />
seed drill performed better, the experimental data revealed<br />
that in chickpea, sorghum and greengram crops, an<br />
additional yield of 14.5, 12.25 and 20.79% was recorded<br />
over the conventional seed drill respectively. The higher<br />
yield is attributed to uniform seed spacing and placement.<br />
50% of labour could be saved over the conventional seed<br />
drill. Evaluation of lifting devices for farm pond revealed<br />
that CRIDA recommended 2 HP, low head and high-speed<br />
petrol start diesel run engine and 1KW capacity solar<br />
surface pump can be successfully used to lift the farm pond<br />
water to irrigate the field by six sprinkler heads. Adoption<br />
of mechanization in the cultivation of pigeonpea was found<br />
more profitable and energy efficient. The net returns and<br />
benefit cost ratio was higher as compared to the farmer’s<br />
practice because of the precise use of inputs such as seeds,<br />
fertilizers, chemicals, etc. Timely completion of various<br />
field operations reduces the crop damage or infections due<br />
to weeding, insects and pest attack, etc. About 20 to 25%<br />
of farm income can be increased by the reducing input<br />
cost through mechanization. Dryland agriculture centre,<br />
Vijayapura has developed automatic compartmental bund<br />
former, from which per day 6 ha area could be covered. The<br />
cost of the compartmental bunding was Rs.450 ha -1 . The sub<br />
soiler is used to puncture the hard pan, so that it facilitates<br />
the infiltration and thus enhances the soil moisture.<br />
Alternate land use systems<br />

In tamarind based horti-pasture system, the fruit yield of<br />
tamarind was significantly higher with the geometry of<br />
10 m x 6 m (678 kg ha -1 ) than 10 m x 3 m (493 kg ha -1 )<br />
and 10 m x 9 m (356 kg ha -1 ). The planting of tamarind in<br />
crop geometry of 10 m x 6 m with guinea grass recorded<br />
maximum system productivity as tamarind equivalent yield<br />
(759 kg ha) and net returns (Rs. 70,750 ha -1 ) and it is best<br />
suitable for shallow black soil/eroded soils.<br />
In aonla based agri-horti systems, the arable crops like<br />
chickpea and safflower + chickpea were grown between<br />
horticulture crops like aonla + henna, aonla + custard apple,<br />
aonla + custard apple+ henna and aonla alone in medium<br />

black soils. Growing chickpea + safflower intercropping in<br />
aonla + custard apple + henna system is the best practice<br />
for higher system productivity and profitability in medium<br />
black soils.<br />
In sapota based agri-horti system, sapota + guava, sapota<br />
+ drumstick and sapota alone were grown in the main plot<br />
and guava, drumstick and no intercrop in the subplot and<br />
chickpea were sown in between horticulture crops as an<br />
intercrop. The system of sapota + guava with drumstick and<br />
chickpea as intercrop is the best system for realizing higher<br />
system productivity and profitability, and the sunflower –<br />
rabi sorghum + chickpea (2:1) sequence cropping system<br />
in sapota plantation found to be profitable and drought<br />
proofing technique in medium black soils.<br />
● In the simarouba-based agri-horti system, simarouba +<br />
guava, simarouba + drumstick and simarouba alone grown<br />
in the main plot and guava, drumstick and no intercrop in<br />
the subplot and chickpea were sown in between horticulture<br />
crops as an intercrop. Among the main plots, significantly<br />
higher chickpea equivalent yield, gross returns and net<br />
returns were obtained with the plantation of simarouba +<br />
guava compared to other horticulture components. The<br />
system of simarouba + guava with drumstick and chickpea<br />
as an intercrop is the best system in medium black soil<br />
for realizing higher system productivity (1739 kg ha -1 in<br />
chickpea equivalent yield) and profitability (Rs.61295 ha -1 ).<br />

grass can be grown in between tamarind rows.<br />
Simarouba based agri-horti system: Simarouba can be<br />
planted at a spacing of 10 m x 10 m. In between the plants of<br />
simarouba within a row and in between rows of simarouba,<br />
guava can be planted. Grow annual crops viz., chickpea,<br />
rabi sorghum etc., in between the rows of simarouba.<br />
Sapota based agri-horti system: Plant sapota grafts<br />
(variety Kalipatti) at 12 m x 12 m spacing in medium to deep<br />
black soils. In between sapota rows, the sowing of sunflower<br />
can be taken up during kharif followed by rabi sorghum +<br />
chickpea (2:1) or green gram during kharif followed by rabi<br />
sorghum + chickpea (2:1) or pearl millet (wider row) during<br />
kharif followed by sunflower (wider row). The annual crops<br />
can be sown till the canopy of sapota trees covers the entire<br />
land.<br />

●<br />
●<br />
●<br />
Graded bunds with strip levelling: The spread of the<br />
technology is to the tune of 50-60% of cultivable dry lands<br />
of Northern Karnataka. The increase in yield was 12-60%<br />
and the economic benefit ranged from Rs. 6000-8000 ha -1 .<br />
Zingg conservation bench terraces: The spread of the<br />
technology is to the tune of 20-30% of cultivable dry lands<br />
of Northern Karnataka. The increase in yield was 10.5-53%<br />
and the economic benefit was in the range of Rs. 12000-<br />
15000 ha -1 .<br />
Vegetative live barriers and mechanical checks: The<br />
technology is practiced in Bijapur, Raichur, H’matti<br />
watersheds, of course the total area coverage is not more<br />
than 2000 ha. The technology was evaluated for rabi<br />
sorghum, groundnut, and chilli. The increase in yield was<br />
20-35% and the economic benefit was in the range of Rs<br />
4000-5000 ha -1 .<br />
In-situ moisture conservation measures: Various in situ<br />
conservation measures viz., furrow and ridges, tied ridges,<br />
compartment bunding, set furrow cultivation and wide row<br />
spacing are being practiced all types of soil in the Northern<br />
Karnataka, these practices cover about 60-70% of the<br />
total dryland. The increase in yield was 10.5-25% and the<br />
economic benefit was in the range of Rs. 8000-10000 ha -1 .<br />
Farm pond technology: The farm ponds are being<br />
dug in all the districts of Northern Karnataka. Under the<br />
Krishibhagya scheme, almost 75000 farmponds was dug.<br />
This increased the cropping intensity and crop diversity in<br />
the farmpond commands.<br />
Crop rotation of pigeonpea + greengram (2:4) rotated<br />
with onion during kharif sequenced with rabi sorghum/<br />
chickpea during rabi: The spread of the technology is<br />
to the tune of 8-10% of cultivable dry lands of Northern<br />
Karnataka. The increase in yield was 12-15 per cent and the<br />
additional economic benefit was in the range of Rs. 15000-<br />
20000 per ha.<br />
● Seed hardening of rabi sorghum and chickpea with 2%<br />
CaCl 2<br />
and cow urine: The technology is practiced in all<br />
districts of northern dry zone, spread of the technology is<br />
20-25% of rabi sorghum and chickpea area. This practice<br />
increased grain yield by 23.7% over conventional practice<br />
and additional economic benefit was in the range of Rs.<br />
3000-3500 ha -1 .<br />

●<br />
●<br />
spread of the technology is to the tune of 15-20% of rabi<br />
sorghum area. The additional economic benefit was in the<br />
range of Rs. 6000-7500 ha -1 .<br />
Adoption of pigeonpea variety TS-3R: The technology is<br />
practiced in all districts of northern dry zone and spread of<br />
the technology is to the tune of more than 80 % of pigeon<br />
pea area. The additional economic benefit was in the range<br />
of Rs.20000-25000 ha -1 .<br />
Alternate land use systems: Among various alternate land<br />
use systems, the Sapota based agri-horti system is more<br />
popular and practiced by farmers of Vijayapura, Bagalkote,<br />
Gadag and Belagavi districts of Karnataka. Around 2 to<br />
5 percent of dryland farmers adopted this technology and<br />
additional economic benefit was in the range of Rs.15, 000<br />
to 20,000 per ha.<br />
Balanced nutrition in rabi sorghum: This technology is<br />
practiced in about 55000 ha. The increase in yield was 10-<br />
15 per cent and the economic benefit was in the range of Rs.<br />
6000-7000 ha -1 .<br />

Brief history of the Centre<br />
On recommendation of the Royal Commission on Agriculture<br />
in India, the first systematic and scientific approach to solve<br />
the problems of dry farming was made in the year 1923 and<br />
systematic research on dry farming in the Scarcity tracts of<br />
Bombay-Deccan was first initiated at Manjari, Pune. The work in<br />
the early years was directed towards soil moisture conservations.<br />
After working for few years, it was realized that the problem<br />
was vast and complex and required simultaneous research on<br />
different aspects such as disposal of rainwater, soil characters,<br />
water requirement of plants etc. The results of these preliminary<br />
investigations formed a basis for an elaborate and comprehensive<br />
programme of research undertaken in the years that followed.<br />
The comprehensive research on rainfall and other climatic<br />
factors, disposal of rain water and soil erosion, physico-chemical<br />
characteristics of soil, physiological studies of important millets<br />
grown in dry tracts, agronomy or soil management was initiated<br />
at Solapur under the guidance of Chief Investigator from 1933.<br />
The dry land agriculture research station was established in<br />
1933 to undertake dry farming research with assistance from the<br />
Imperial Council of Agricultural Research, Delhi. It was then<br />
made permanent feature of the State Department of Agriculture<br />
after 1944. A technique known as Bombay Dry Farming Method<br />
laid stress on better utilization of moisture by reducing plant<br />
densities and better inter cultivation. Fertilizer use was not<br />
envisaged at that time, crop and varietal diversity was also not<br />
adequate which resulted in emphasizing the growing of few<br />
crops only. Further, weather observations were not considered<br />
to plan different strategies of crop production. The All India Coordinated<br />
Research Project for Dryland Agriculture centre was<br />
started in 1970-71 at Solapur.<br />
Agro-climatic zone characteristics<br />
is during first fortnight of June and normal withdrawal is during<br />
first fortnight of October. The mean maximum temperature and<br />
mean minimum temperature in the zone are 33.6°C and 19.9°C,<br />

Ridges and furrows for in-situ moisture conservation<br />
Compartmental bunds are preferred where the infiltration<br />
rate of the soil is moderate and land slope is less. Before<br />
preparing the compartments, the land is prepared with<br />
primary tillage operation. Then with the help of bullock<br />
drawn Baliram plough / ridger or tractor drawn ridger, the<br />
compartments of varying sizes from 6 m x 6 m to 10 m x<br />
10 m with 20-25 cm ridge height are prepared depending on<br />
the type of soil and slope. The cost of making compartment<br />
bunds is Rs. 1500 ha -1 . The main purpose of making<br />
compartment bunds is in situ conservation of rain water<br />
during kharif, to avoid soil erosion and to store more water<br />
in soil profile which is useful for rabi crops. The tractor<br />
drawn bund former developed by Department of FMPE and<br />
AICRP on FIM, MPKV, Rahuri is very useful in making<br />
compartment bunds of 2 x 6 m with effective field capacity<br />
of 4-5 ha per day.<br />
The farm pond is standardized. The excess runoff water<br />
is stored in these ponds. The ponds are lined with suitable<br />
lining materials like polythene film to prevent seepage<br />
losses. On the outer side slopes of the pond, the vegetation/<br />
grasses are grown to avoid scouring. The harvested water<br />
is used for giving protective /supplemental irrigation to the<br />
crops at critical growth stages.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
The rainwater management technologies viz., compartmental<br />
bunding and ridges and furrow method of in-situ moisture<br />
conservation were upscaled through State Department of<br />
Agriculture. The farm pond technology implemented and<br />
upscaled in farmers field through special mission implemented<br />
by State Department of Agriculture ‘Magel tyala Shet Tale’<br />
(Farm pond who demand), Shet Tale Astarikaran (Lining for<br />
farm pond), National Horticultural Mission project.<br />
The tractor drawn compartmental bund former required for<br />
preparation of compartmental bunds for in-situ moisture<br />
conservation was developed by AICRP on Farm Implements and<br />
Department of FMP, MPKV, Rahuri based on the feedback given<br />
by Operational Research Project of AICRPDA, Solapur. The<br />
subsidy has been provided for purchase of different implements<br />
through Farm Mechanization Scheme under RKVY. Also<br />
theustom hiring of farm implements is being upscaled through<br />
Implements Bank (Avajare Bank) scheme under RKVY project.<br />
The flagship programme of State Government ‘Jalyukt Shivar’<br />
is focussed on water conservation activities and it includes the<br />
recommendation given by AICRPDA Centre regarding desilting<br />
of cement nala bunds for maintaining its storage life.<br />

The recommended package of practices for cereal, oilseed and<br />
pulse crops were demonstrated by the State Department of<br />
Agriculture under National Food Security Mission programme.<br />
Also, the rainfed technologies developed under AICRPDA<br />
Centre are included in the package of practices under Nanaji<br />
Deshmukh Krishi Sanjivani Prakalp Project on Climate Resilient<br />
Agriculture (POCRA) funded by World Bank and implemented<br />
by State Department of Agriculture being implemented in 5142<br />
villages located in 15 districts of Marathwada, Vidarbha and<br />
North Maharashtra.<br />
The training to the farmers and officials of project implementing<br />
agencies regarding AICRPDA technologies are being given<br />
through ‘Sheti Shala’ component of NFSM. The themewise<br />
Skill Training of Rural Youth (STRY) were organised<br />
by ATMA, Solapur in association with State Agricultural<br />
Management and Extension Training Institute (SAMETI),<br />
Maharashtra and National Institute of Agriculture Extension<br />
Management (MANAGE).<br />
All technologies under rainwater management, crops and<br />
cropping systems, integrated nutrient management, participatory<br />
varietal selection/crop improvement, energy management theme<br />
were published in different leaflets / folders / local language<br />
newspapers as well as Krishi Diary of Mahatma Phule Krishi<br />
Vidyapeeth (Krishi Dainandini every year) and the same<br />
technologies were demonstrated and upscaled in farmer’s field<br />
in collaboration with KVKs, ATMA, State Department of<br />
Agriculture and NGOs.<br />
District wise contingency plan and various drought proofing<br />
action plans in the domain agro-climatic zones of the centre<br />
were upscaled during 2005 and 2017 funded by Department<br />
of Agriculture and Cooperation, Ministry of Agriculture and<br />
Farmers’ Welfare, Govt. of India through CRIDA, Hyderabad.<br />
These were implemented in the state with the help of Maharashtra<br />
State Department of Agriculture. The centre, in collaboration<br />
with AICRP on Agrometeorology issues weekly weather based<br />
agro-advisories to the 70,000 farmers regarding climate situation<br />
and real time contingency measures that has to be followed and<br />
published in local newspapers, issued messages in different<br />
WhatsApp group of farmers of N<strong>ICRA</strong> villages, OFR villages,<br />
etc. in domain districts (Solapur, Ahmednagar, Sangli, Satara,<br />
Pune, Dhule, Jalgaon, Nandurbar, Kolhapur).<br />
Alternate land use management practices, viz, intercropping in<br />
custard apple and aonla, was upscaled through NHM scheme.<br />
The SHG’s and FPO operating at village level helped in upscaling<br />
of dryland technologies. All the AICRPDA technologies were<br />
evaluated and upscaled through front line demonstrations in<br />
farmers field, organised field day, farmers rallies, training to<br />
stake holders etc., in the domain area through KVK’s of SAU’s,<br />
ATMA and other line departments operating in the zone.<br />
Potash fertilizer management in dryland crops of Scarcity<br />

New Delhi implemented under AICRPDA developed different<br />
technologies viz., i) Application of 20 kg K 2<br />
O for blackgram<br />
followed 50 kg K 2<br />
O for rabi sorghum, ii) Application of 50<br />
kg K 2<br />
O for pearlmillet followed 20 kg K 2<br />
O for chickpea iii)<br />
Application of 50 kg K 2<br />
O for pearlmillet followed 20 kg K 2<br />
O for<br />
safflower found suitable for increasing the yield by 15 to 20%<br />
over recommended dose of potash application and sustaining<br />
the potassium status in soil. The upscaling, assessment and<br />
refinement of AICRPDA technologies has been done through<br />
AICRPDA-Operational Research Project implemented in six<br />
villages of Solapur, Sangli and Satara district of Maharashtra<br />
state.<br />
Tank silt as an organic amendment for improving soil and water<br />
productivity is upscaled through the FPARP project funded<br />
by Ministry of Water Resources, New Delhi through ICAR-<br />
CRIDA, Hyderabad in five villages of Solapur district. This<br />
resulted in increase in the yield of rabi sorghum by 20-25 per<br />
cent over farmers practice (without tank silt application). The<br />
early maturing (95 days) horsegram genotype Phule Sakas as<br />
compared to ruling varieties viz; Man (115 days) and Sina (130<br />
days) developed at AICRPDA, Solapur center in collaboration<br />
with AICRP on Arid Legumes is being upscaled through seed<br />
production programme of university and FLDs.<br />
Under the ICAR-CRIDA funded NATP RNPS-2 Project<br />
implemented at Village–Wadala of North Solapur Taluk<br />
in Solapur District of Maharashtra (2000-2005), regional<br />
scale watershed plan and methodologies for identification of<br />
critical areas for prioritized land treatment in the watershed<br />
was developed for nutritious cereal production. Under the<br />
ICAR-CRIDA funded NATP TAR-IVLP Project (1996-<br />
2003), Technology Assessment and Refinement was carried<br />
out through Institution-Village Linkage Programme at Village<br />
Ratanjan of Barshi, Solapur and demonstrated that sustainability<br />
in rural livelihood of dry land areas can be achieved through<br />
improved crop management as well as with interventions of<br />
animal and poultry birds. The NWDPRA Projects (1999-2001)<br />
funded by NABARD implemented at Gulpoli & Turk Pimpari,<br />
Tal.Barshi, Dist.Solapur, upscaled the technologies viz., for<br />
better germination and production of rabi sorghum on sodic soil.<br />
Around 7.5 t ha -1 FYM + 15 t ha -1 murum should be applied and<br />
mixed with upper soil layer and soil health management for rabi<br />
sorghum with 25 kg N ha -1 through sorghum byre waste + 25 kg<br />
N ha -1 urea for saving of 50 per cent chemical fertilizer (urea).<br />
Short duration legumes (cowpea, greengram, etc.) can be used<br />
successfully as green manure crop for dryland rabi sorghum<br />
technology and is upscaled through ICAR Cess funded Ad-hoc<br />
project (1998-2002).<br />
The Custom Hiring Centre (CHC) for farm implements/<br />
machinery in Narotewadi village of North Solapur is established<br />
in the year 2011 by AICRPDA Centre, Solapur under National<br />
Innovations in Climate Resilient Agriculture (N<strong>ICRA</strong>). This
CHC is enabling the farmers to hire farm implements/machinery<br />
at an affordable cost for various agricultural operations in<br />
various crops with high energy use efficiency. This has enabled<br />
timely operations and promoted small farm mechanization.<br />
Also the real time contingency measures are being upscaled in<br />
N<strong>ICRA</strong> villages. It is necessary to upscale through SHGs, FPOs,<br />
NGOs, etc. for getting higher prices by exporting or processing<br />
the farm produce.<br />
Impact of dryland technologies<br />
The practice of making compartment bunds during kharif season<br />
for in-situ moisture conservation conserved 35% more moisture<br />
than farmers practice (two harrowing only) and increased grain<br />
yield of rabi sorghum to the tune of 2.0 q ha -1 .The net returns of<br />
Rs.9192, B:C ratio of 1.63 and RWUE of 8.43 kg ha -1 mm -1 were<br />
observed under compartment bunding compared to farmers’<br />
practice (Rs.5240, 1.43 and 6.84 kg ha -1 mm -1 ). The practice is<br />
widely adopted in 20% of rabi sorghum grown area in Solapur<br />
district. The compartment bunding was adopted by Govt. of<br />
Maharashtra and implemented with government cost on wide<br />
scale in dryland areas. This was more and widely accepted<br />
programme by the farmers. The practice of ridges and furrows<br />
during kharif for in-situ moisture conservation conserves 45%<br />
more moisture than farmers’ practice (two harrowing only) and<br />
retains it for longer period (up to 60 days) and increases rabi<br />
sorghum yield (1091 kg ha -1 ) by 53%.<br />
The farm ponds are useful in harvesting excess runoff and the<br />
harvested water can be used for supplemental irrigation / protective<br />
irrigation to crops / orchards during dry spell or after rainy<br />
season. The productivity and income of rainfed crops provided<br />
with single critical/supplemental irrigation with harvested water<br />
was doubled. The yield, net returns and B:C ratio of chickpea<br />
irrigated with harvested rainwater were 1021 kg ha -1 , Rs. 19053,<br />
1.52 respectively compared to chickpea without irrigation (695 kg<br />
ha -1 , Rs. 3919 and 1.11). The RWUE for chickpea with irrigation<br />
was 17.01 and without irrigation was 11.58 kg ha -1 mm -1 . The<br />
sustainable yield index (SYI) for chickpea with irrigation was<br />
1123.4 and without irrigation was 794.8.<br />
Instead of keeping deep black soil fallow in kharif, short duration<br />
pulse crop viz., blackgram / greengram / cowpea are grown<br />
followed by rabi sorghum. Under normal rainfall conditions,<br />
the pulses are grown for grain purpose and under abnormal<br />
conditions pulses are grown either for fodder or green manuring.<br />
It improves the soil fertility and saving of 25 % nitrogen<br />
recommended dose for sorghum. There was an increase in net<br />
returns by Rs.38928/ ha with B:C ratio of 2.03 compared to rabi<br />
sorghum alone (Rs.29775 and B:C ratio 1.79). This practice is<br />
adopted on 20 per cent of rabi sorghum area in domain districts.<br />
The improved sunflower + pigeonpea (2:1) system has been<br />
adopted in 30% area under sunflower in Solapur district (6500<br />
ha), while pearl millet + pigeonpea (2:1) was adopted in about<br />
10 % area under pearl millet in Ahmednagar, Pune and Dhule<br />
districts (80000 ha) in Maharashtra. There is a lot of scope for<br />
enhancing the area under improved intercropping systems due<br />
to risk minimization and attaining higher monetary returns. The<br />
improved intercropping systems gave about 30% increase in<br />
productivity and net returns compared to farmers practice. The<br />
net returns were Rs.11313 ha -1 from sunflower + pigeonpea and<br />
Rs.10580 ha -1 from pearl millet + pigeonpea systems with BC<br />
ratio of 1.76 and 1.74 respectively. In sunflower, net returns of<br />
Rs.6000 with B:C ratio of 1.18 and in pearl millet net returns of<br />
Rs.6500 with B:C ratio of 1.20 were observed.<br />
Seed treatment with azotobactor @ 25 g per kg of seed before<br />
sowing and application of 50 kg N + 25 kg P 2<br />
O 5<br />
+ 25 kg K 2<br />
O<br />
ha -1 at the time of sowing on light to medium soil can mitigate<br />
drought severity, 38% increase in grain yield of rabi sorghum<br />
over no application of potash with 3.48 B:C ratio and 20%<br />
increase in grain yield of pearl millet over no application of<br />
potash with B:C ratio of 2.10. Net returns and B:C ratio of potash<br />
applied to pearl millet and rabi sorghum were Rs. 8893 and<br />
Rs. 12320 respectively compared to farmers’ practice of pearl<br />
millet (Rs. 6324) and rabi sorghum (Rs. 9870). This improved<br />
practice has been adopted in 10 to 15% of pearl millet and rabi<br />
sorghum area in domain districts.<br />
The suitable sorghum varieties for shallow soils (upto 30 cm)<br />
are Selection-3, Phule Anuradha, medium soils (upto 60 cm) are<br />
Phule Maulee, Phule Suchitra and deep soils (60 cm and above) are<br />
Phule Vasudha, Phule Yashoda. The yield increase of Selection-3,<br />
Phule Anuradha (shallow soils) was 15%, Phule Maulee, Phule<br />
Suchitra (medium soils) was 15-20% and Phule Vasudha, Phule<br />
Yashoda (deep soils)was 25-30% over local variety Dagadi. The<br />
net returns and B:C ratio of Selection-3, Phule Anuradha (shallow<br />
soils) were Rs.9890 and 2.1, Phule Maulee, Phule Suchitra<br />
(medium soils) were Rs.11890 and 2.2 and Phule Vasudha, Phule<br />
Yashoda (deep soils) were Rs.10560 and 2.7 over local variety<br />
Dagadi. Adoption in shallow soils was 15-20%, medium soils was<br />
30-35 and deep soils was 35-40% in domain area.<br />
One harrowing + sowing with seed drill and light harrowing<br />
+ one hoeing and 25 kg N through inorganic fertilizer (urea)<br />
and 25 kg N through organic fertilizer through crop residue<br />
and Leucaena loppings (50% nitrogen through crop residue<br />
(byre waste) + 50% Leucaena lopping) + 12.5 kg P 2<br />
O 5<br />
through<br />
fertilizer (SSP) is recommended for rabi sorghum grown on<br />
medium deep black soils in scarcity zone of Maharashtra for<br />
getting higher yield and monetary returns with minimum energy<br />
use and maintaining soil fertility. The improved tillage and<br />
nutrient management practice gives grain yield of 1706 kg ha -1<br />
and stover yield of 4084 kg ha -1 while conventional tillage gives<br />
grain yield of 1350 kg ha -1 and stover yield of 3429 kg ha -1 . The<br />
net returns and B:C ratio with improved technology were Rs.<br />
64879 and 4.21 compared to farmers’ practice (Rs. 45854 and<br />
3.18). This improved practice has been adopted in 15 to 20% of<br />
rabi sorghum area in domain districts.<br />
67
Application of 25 kg N ha -1 through chaffed sorghum byre<br />
waste (5 t) + 25 kg N ha 1 through Leucaena loppings (3.5 t)<br />
is recommended for rainfall zone-IV of scarcity zone of<br />
Maharashtra for improvement in yield of rabi sorghum and soil<br />
quality. The improved technology gives 12.38 q ha -1 grain yield<br />
and 33.47 q ha -1 stover yield and they were higher than RDF of<br />
50 kg N ha -1 through urea (11.82 and 32.96 q ha -1 respectively).<br />
However, significant improvement in the soil fertility at harvest<br />
of rabi sorghum would be more beneficial for sustainable<br />
productivity of sorghum with improvement in soil health. This<br />
integrated nutrient management has been adopted in 15 to 20%<br />
of sorghum area in domain districts.<br />
For improving of soil fertility and higher yield of pearl millet,<br />
two harrowing before sowing and one weeding at 15-20 days and<br />
one hoeing at 30-35 days after sowing and application of 25 kg<br />
N per ha through organics (FYM 5 t ha -1 and Leucaena loppings<br />
1.75 t ha -1 ) and 25 kg N and 25 kg P 2<br />
O 5<br />
ha -1 through fertilizer is<br />
recommended. It gives higher grain yield of pearl millet (835 kg<br />
ha -1 ) over 100% organic N (620 kg ha -1 ) and gave maximum net<br />
profit of Rs. 3982 ha -1 over 100% organic N (Rs. 5240 ha -1 ). This<br />
integrated nutrient management has been adopted in 15 to 20%<br />
of sorghum area in domain districts.<br />
Integrated farming system (IFS) model of 1.0 hectare rainfed<br />
area comprising 50% crop component, 40% horticulture<br />
component, 5% animal component and 5% farm pond is<br />
recommended for economic viability of small farmers under<br />
Scarcity Zone of Maharashtra. The average net returns from IFS<br />
were Rs. 76664 with B:C ratio of 2.0 compared to rabi sorghum<br />
alone (Rs. 14928 with 1.5 B:C ratio). In IFS, the contribution of<br />
crop component was 11%, horticulture component was 10% and<br />
animal component was 79% to the net returns.<br />
Amrutsagar et al.<br />
Application of 25 kg N ha -1 through FYM @ 5.0 t ha -1 + 25 kg<br />
N through urea + 25 kg P 2<br />
O 5<br />
ha -1 through single super phosphate<br />
is recommended for maintaining soil health, higher grain and<br />
stover yields and monetary returns of rabi sorghum grown on<br />
medium deep black soil in scarcity zone of western Maharashtra.<br />
The improved technology gave maximum grain yield (1448<br />
●<br />
kg ha -1 ) and stover yield (3688 kg ha -1 ) with higher net returns<br />
(Rs.30066 ha -1 ) compared to farmers’ practice (833 kg grain<br />
yield ha -1 , Rs.14254 of net returns). This helps in maintaining ●<br />
soil health and reduces 50% of nitrogen from chemical fertilizer<br />
dose. This improved practice has been adopted in 15 to 20% of<br />
rabi sorghum grown area in domain districts.<br />
●<br />
The horse gram genotype (Phule Sakas) is early maturing (95<br />
days) as compared to ruling varieties viz; Man (115 days) and<br />
Sina (130 days). The variety is having bolder seed with brown ●<br />
colour. The culture is non shattering type, being erect in habit<br />
pods, do not touch to the ground and prevent damage to the<br />
●<br />
pods. The genotype is having high protein (22.09%) and less<br />
tannin (1.14%) content. The culture is moderately resistant to<br />
yellow mosaic virus and minimum and comparable incidence of<br />
white flies (1.18 flies per plant).<br />
68<br />
The average seed yield is 1025 kg ha -1 in station and University<br />
Multilocation trials. The culture (1025 kg ha -1 ) has shown<br />
42.55% increased seed yield over the early check Man (719<br />
kg ha -1 ) and 31.41% over the second check Sina (780 kg<br />
ha -1 ). Whereas, at national level, it has given 19.26% increase<br />
seed yield over the national check AK-42. The net returns were<br />
Rs. 8870 compared to Man (Rs. 6280) and Sina (Rs. 6580). It was<br />
adopted in 25% area of millets in domain district. The location<br />
specific constants K, a, b and d in intensity -frequency-duration<br />
relationship was developed for Solapur, Pandharpur and Jalgaon<br />
region and used for estimation of runoff. The estimation of runoff<br />
is required for design of soil and water conservation structures.<br />
Timely operations of seeding and fertilizer application are<br />
carried out simultaneously with the help of bullock drawn two<br />
bowl ferti seed drill. This improves fertilizer use efficiency and<br />
enhances the productivity of crops up to 20%. The cycle hoe<br />
performs efficiently on the farmer’s fields with a reduction in<br />
drudgery for hoeing operation. It is also convenient for women<br />
to operate. One labour can cover one acre/day. The bullock<br />
drawn multi-purpose Phule seed drill implement can be used<br />
for sowing, harrowing and also as a cultivator and are suitable<br />
for all soil types and crops, and even for sowing of intercrops.<br />
By using this implement, saving of one labour and timely and<br />
efficient agricultural operation is ensured. Further, upscaling of<br />
this practice can be done in different districts with similar agro<br />
ecological features through more extension efforts and linkage<br />
with line departments, and through demonstrations by ATMA,<br />
KVKs and NGOs etc.<br />
Way forward<br />
●<br />
The research should be focussed on crop and cropping<br />
systems, resource management, evaluation of improved<br />
dryland varieties, integrated nutrient management,<br />
integrated farming system and arid legumes viz., clusterbean,<br />
rajma bean, cowpea, pigeonpea, horsegram, mothbean and<br />
pearl millet.<br />
Development of new drudgery reduction implements for<br />
the rainfed farmers especially for rabi sorghum, pigeonpea,<br />
sunflower, pearl millet and safflower are also needed.<br />
Development of new technologies related to sequestration<br />
of atmospheric carbon, soil health management are also<br />
essential.<br />
Mechanization in dryland agriculture, development of hand<br />
tools and equipment for drudgery reduction for small and<br />
marginal farmers are also required.<br />
Development of Integrated farming system module for<br />
small, marginal and medium land holdings.<br />

Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Centre was established at Udaipur in 1976.<br />
The Centre was upgraded to the Main centre along with the<br />
Operational Research Project (ORP) and shifted to Agriculture<br />
Research Sub Station, Arjia, Bhilwara in 1984.<br />
Agro-climatic zone characteristics<br />
The Centre is located in Southern zone (NARP) in Rajasthan<br />
and in the Agroecological subregion (ICAR) 4.2 and in the<br />
Western plateau and hills agroclimatic region (Planning<br />
Commission). The climate in this zone is semi-arid. Out of<br />
the total annual average rainfall of 657.7mm, the south-west<br />
monsoon contributes 93.1% while 3.7% and 3.2% is from northeast<br />
monsoon and summer. The normal onset of monsoon is<br />
during first week of July and the normal withdrawal of monsoon<br />
is during first week of October. The historical rainfall data (of 30<br />
years) indicated that the rainfall during south-west monsoon had<br />
been deficit by 17% of the average rainfall. The dry spells during<br />
crop season were experienced during September coinciding with<br />
reproductive stages of the major rainfed crops. Mean monthly<br />
rainfall is highest in August and lowest in February. Rainfall is<br />
relatively more erratic during rainy season (June – September).<br />
After every 3-5 years drought situations generally occurred and<br />
mid season and terminal drought situation occurrence is common<br />
phenomena in the zone, so that most crops affected adversely<br />
during kharif season. In the month of July and August mostly<br />
excess rainfall events occurs. Summers are hot and winters are<br />

region. Research activities primarily focussed in the identified<br />
thrust areas of resource characterization, cropping systems,<br />
rainwater management, integrated nutrient management, farm<br />
mechanization and alternate land use. Centres technologies<br />
enhanced production and increased income of farm families in<br />

Significant achievements and findings<br />
All India Coordinated Research Project for Dryland Agriculture<br />
(AICRPDA) centre at Agricultural Research Station, Udaipur,<br />
and Dryland Farming Research Station, Arjia have developed<br />
location-specific dryland technologies to cope with production<br />
constraints in the domain area. The key technologies are<br />
classified under resource characterization, catchment command<br />
relationship, rainwater harvesting, and recycling, in-situ moisture<br />
conservation, crops and cropping systems, participatory varietal<br />
selection of dryland crops, contingency crop plan to cope with<br />
delays in monsoon and during dry spells, integrated farming<br />
Rainwater management<br />
In-situ moisture conservation through flat sowing and ridging<br />
after first interculture improve different crops yield and widely<br />
adopted by the farmers of the zone. Soil and water losses reduced<br />
by adopting in-situ conservation practices like application of<br />
FYM @ 5 t/ha and vertical mulch of sesame straw @ 5 t/ha<br />
at 10 m interval reduced runoff, soil loss, increased water use<br />
efficiency, physical and biological properties like dehydrogenase<br />
and phosphotase activities of soil and also increased the yield<br />
of maize. Among various types of bunds tested, contour bund<br />
proved most effective in conserving soil and water and for<br />
increased yields of grass and tree growth. In Inceptisol soils of<br />
south Rajasthan, summer disc ploughing followed by cultivator<br />
recorded highest water use efficiency and produced lowest<br />
runoff and soil loss in the region. To overcome the adverse<br />
effect of sub-soil compaction in inceptisols and to break the hard<br />
pan in subsoil, ploughing with a Vibro chisel plough up to 40-70<br />
cm depth at one and half meter interval once in two years was<br />
found useful and recorded 26.72% higher maize grain yield as<br />
compared to cultivator.<br />
systems, energy management and alternate land use etc. The<br />
Also, research over the years revealed that the region experiences<br />
significant achievements of the center since its inception are<br />
an average of 7-11 runoff events per year resulting in 2-2.5 tons<br />
briefly described under the following themes.<br />
of soil loss per hectare. The following are the significant findings<br />
Resource characterization<br />
The weather and soil data was analysed for resource<br />
characterization to characterize the earliest probable sowing<br />
time and defining the risk level in arable farming. Under<br />
dynamic and contingent crop planning for proactive monsoon<br />
over the years that found efficient for effective rainwater<br />
management. Dug-out ponds with the lining of calcareous soil<br />
recorded a minimum seepage rate (1.05-1.08 cm/sq m/day) and<br />
reduced the seepage by 62 percent as compared to the unlined<br />
ponds.<br />

Crops and cropping systems<br />
Crops and cropping systems help to cope with any adverse<br />
events like rainfall variability and drought. The cropping systembased<br />
strategies for drought mitigation in the domain area of<br />
AICRPDA- Arjia centre includes growing crops and varieties<br />
that fit into variable rainfall situation year to year. The maize<br />
varieties; Navjot, Pratap Makka (Composite)-3, Pratap Sankar<br />
Makka-3 PHM-3, PHM-5, PM-9, Pratap Maize Chari-6, DHM-<br />
117, DHM-121, HQPM-1, PQPHM-1, and blackgram varieties<br />
like PU-31, Pratap Urd-1, Mukndra-2, and KU-96-3 are suitable<br />
for rainfed conditions due to their tolerance to drought, early<br />
duration, and higher seed yield. Improved varieties recorded 12<br />
to 18% higher yields than the local varieties.<br />
Best yields of maize and sorghum were achieved when sown<br />
with blackgram and greengram as intercrops during the last week<br />
of June to 1 st week of July. Intercropping of maize + blackgram<br />
(2:2) as paired row ratio instead of sole maize was found more<br />
beneficial and adapted by large number of farmers of the zone.<br />
If rainfall is delayed by a week (2 nd fortnight of July), sowing of<br />
contingent crops such as blackgram, greengram, cluster bean,<br />
cowpea, and sorghum/ fodder sorghum are found profitable in<br />
the domain area. Among different rainfed crops, blackgram,<br />
cluster bean and sorghum can be grown as better alternate crops<br />
to maize in rainfed Inceptisols and vertisol as these crops gave<br />
maximum maize equivalent yield over years. Higher maize<br />
equivalent yield was recorded with strips of maize (grain) in 2/3<br />
area + strips of maize chari fodder (1/3) area cropping system.<br />
Higher net returns were also recorded with maize + blackgram<br />
(6:6) row ratio at 45 cm, groundnut + pigeonpea (2:2), maize +<br />
soybean (2:2), castor + greengram (1:2) and groundnut + sesame<br />
(2:2) intercropping systems.<br />
The fodder crops sown during delayed onset of monsoon,<br />
maize Chari fodder and fodder sorghum were found efficient<br />
in fodder production. Fodder sorghum and fodder maize are<br />
potential forage cereals because they can produce more quantity<br />
and quality fodder while also ensuring net monetary returns.<br />
Napier and Lucerne are also grown under partially irrigated<br />
areas of dryland regions for round the year in the domain area.<br />
Application of quizalofop-ethyl @ 50 g ha -1 at 30 days after<br />
sowing in blackgram significantly increased seed yield by 20.21<br />
percent in comparison to weedy check.<br />
Nutrient management<br />
Under integrated nutrient management in maize, application of<br />
FYM @ 10 t ha -1 RDF (N90 P30 K30) and seed inoculation with<br />
azotobacter and PSB significantly increased yield attributes<br />
and yield (43.89%) over control. However, it has also improved<br />
the N, P, and K status of soil by 2.78, 4.31 and 8.56 kg ha -1 ,<br />
respectively, and improved the nutrient content and uptake in<br />
grain and stover as compared to the control.<br />
Management of zinc deficiency in rainfed maize, application<br />
of soil test based fertilizer (STBF) + zinc sulphate @ 25 kg<br />
ha -1 ; STBF + P 33 microbial culture (seed treatment) and STBF<br />
+ P29 microbial culture (seed treatment) at the time of sowing<br />
of rainfed maize increased yield significantly by 55.63% with<br />
application of ZnSO 4<br />
@ 25 kg/ha but it was found at par with 33<br />
microbial culture (42.55%) and P29 microbial culture (45.88%)<br />
over control. Application of K 2<br />
O @ 40 kg ha -1 increased maize<br />
yield (19.6%) over control (2066 kg ha -1 ). Similarly, application<br />
of 30 kg MgSO 4<br />
.7H 2<br />
O ha -1 increased the maize grain yield by<br />
25.9% over control. It also increased the availability of K and<br />
Mg status in soil after harvest of maize crop.<br />
Taramira crop was sown in conserved moisture, application<br />
of RDF (N20:P30:K0) with azotobacter + PSB seed treatment<br />
and spraying of vermiwash @ 7.5% at flower initiation and pod<br />
formation stage increased seed yield by 60% as compared to<br />
control (296 kg/ha).<br />
Fifteen years of long-term integrated nutrient management<br />
experiment conducted at AICRPDA, Arjia revealed that,<br />
application of 25 kg N through FYM and 25 kg N through<br />
inorganic fertilizer + 30 kg P 2<br />
O 5<br />
gave highest mean maize grain<br />
equivalent yield (3533 kg/ha) as compared to control (2057<br />
kg/ha) with an increase of 71.72%. However, applications of<br />
organic treatments significantly affected the organic carbon,<br />
available nitrogen, phosphorus and potassium in both layers (0-<br />
15 and 15-30 cm depth) and recorded higher with the application<br />
of 25 kg N through FYM and 25 kg N through inorganic fertiliser<br />
+ 30 kg P 2<br />
O 5.<br />
In maize, foliar application of soluble complex fertilizer NPK<br />
(19:19:19) @ 0.5% + zinc sulphate @ 0.5% at both knee high<br />
and before tasseling stages increased the maize yield by 32<br />
percent as compared to control. However, mitigate the dry spell<br />
stress effect in blackgram, by spraying NPKS (18:18:18:6) @<br />
2% before flowering and pod filling stage produced 31% higher<br />
blackgram seed yield over control (1074 kg /ha).<br />
Energy management<br />
Among different seed drills/planters tested for maize sowing,<br />
tractor-drawn nine row Arjia intercropping seed drill has sown<br />
maize + blackgram (2:2) intercropping system (paired row) with<br />
optimum seed rates of maize and blackgram. An interculture<br />
implement (tractor operated weeder) was fabricated with row<br />
distance adjustment for intercultivation in maize, blackgram and<br />
intercropping system. Tractor drawn interculture implements<br />
perform weeding and also ridging simultaneously. The strip<br />
cropping of maize + blackgram (4:8) with deep tillage and<br />
ridging after one interculture operation (RAFIO) was more<br />
energy efficient and increased the energy use efficiency by 33.35<br />
percent in deep tillage as compared to shallow tillage. Arjia<br />
wheel hoe developed by the centre for all crops was fabricated<br />
71
and tested in the field conditions is becoming popular among<br />
marginal and small farmers of the district. The field capacity of<br />
the Arjia wheel hoe has been found to be 6.55 man/day ha -1 as<br />
compared to kudali (23.9 man/days ha -1 ). Dept. of agriculture,<br />
Dist Bhilwara included the equipment in its subsidy scheme for<br />
upscaling.<br />
Alternate land use systems<br />
The soils of the domain area are large, marginal and uncultivated<br />
waste land which are sandy loam, shallow in depth, undulating<br />
topography and poor in soil fertility. Class IV and V lands of<br />
zone IV-Arjia Rajasthan are hilly (4-15%) with these lands<br />
having only some trees and local grass species such as Aristida.<br />
These unproductive degraded pasture class V land can be made<br />
productive with silvi-pastoral system and recorded 239% more<br />
Cenchrus setigerus dry grass yield as compared to the control.<br />
Further, class V unproductive lands made productive by sowing<br />
Cenchrus setigerus as mud pellets/ balls with the application of<br />
20 kg N and 30 kg P 2<br />
O 5<br />
per hectare each year and recorded 103<br />
percent higher dry grass yield as compared to local pasture. Also<br />
with agri-horti aonla based system and integrated with different<br />
need based crops and grasses like aonla+ sesame, aonla +<br />
pumpkin, aonla + aswagandha and aonla + stylosanthes hamata<br />
in class iv land as compared to fallow land. Further, unproductive<br />
class IV lands made productive with agri-horti system like ber +<br />
papaya + greengram, ber + papaya+ blackgram, guava + papaya<br />
+ groundnut as compared to fallow land.<br />
Integrated farming system<br />
The research revealed that, for a farm of 1 ha of land, maize as<br />
a kharif rainfed crop with cow rearing (2) improved the total<br />
net returns by 92 percent compared to crop alone. Besides, it<br />
provides 67 man days of employment after harvest of maize to<br />
the farmer. Similarly, under partial irrigated conditions, agrihorti<br />
system groundnut + guava integrated with cow (2) + goat<br />
(2) rearing is an appropriate system in class IV land for semi arid<br />
region of Bhilwara for the best use of available natural resources.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
AICRPDA centre Arjia has developed many location-specific<br />
dry land technologies for the benefit of farmers. Successful<br />
technologies were upscaled in convergence with Govt.<br />
programmes, NGOs, and KVKs after demonstrating in the<br />
farmer’s field. In convergence, the collaborated institutes<br />
encouraged the farmers to adopt these technologies to cope
with the climate vagaries and also enhance the productivity of<br />
rainfed crops in the zone. The technologies developed by the<br />
centre were adopted by the Department of Agriculture, Govt. of<br />
Rajasthan, KVKs, NGOs and also included in the Zone IV-arjia<br />
package of practices (PoP) of MPUAT Udaipur.<br />
Impact of technologies<br />
The dryland technologies developed by AICRPDA - Arjia have<br />
significantly improved the productivity of rainfed crops grown<br />
in dryland areas of Rajasthan. Farm pond technology is one such<br />
technology that is more popular, climate resilient and successful<br />
in rainwater harvesting and mitigating the zone’s frequent dry<br />
spells. The impact of technologies was clearly visible with<br />
increased productivity, yield stability and improved livelihoods<br />
for farmers in the region. The impact of the technologies in terms<br />
of yield enhancement and overall productivity improvement in<br />
the zone are shown below.<br />
Rainwater management<br />
●<br />
●<br />
In-situ moisture conservation model for maize/ sorghum<br />
and maize + blackgram (2:2) crop and cropping system<br />
practices increased the maize equivalent yield by 21-25%<br />
as compared to farmer’s practice.<br />
Utilization of harvested rainwater in maize + blackgram<br />
(2:2) and groundnut + sesame (6:2) intercropping system.<br />
Supplemental irrigation increased the maize and groundnut<br />
equivalent yield by 15-28%<br />
Crops and cropping systems<br />
●<br />
●<br />
●<br />
●<br />
Intercropping system maize + blackgram (2:2) and<br />
groundnut + sesame (6:2). Both intercropping systems<br />
practiced by the farmers in medium to deep soil increased<br />
the grain yield by 25-47% in domain area. They get<br />
approximately an additional income @ Rs. 4966 - 8435 per<br />
ha -1.<br />
Intercropping system sorghum + greengram (2:1) and<br />
blackgram + sesame (2:2). These intercropping systems<br />
were practiced by the farmers in shallow to medium-depth<br />
soil and increased the grain yield by 21-34% in the domain<br />
area. They get an approximately additional income of Rs.<br />
2587-3945 ha -1<br />
Contingency crop planning reduced the weather risk and<br />
brought stability under delayed monsoon situation as<br />
contingent measure sorghum (fodder) and greengram was<br />
sown. If monsoon is very delayed, then in place of the<br />
kharif crop, taramira can be sown during September.<br />
Sorghum, cluster bean, greengram and cowpea, can be<br />
grown as alternate crops to maize and these crops were<br />
grown successfully by the farmers in Bhilwara region.<br />

Enhancing productivity of rainfed maize through use of<br />
agro-chemicals (Foliar spray of KNO 3<br />
, soluble NPK, and<br />
thiourea). Foliar spray of 1% KNO 3<br />
, soluble 1% NPK, and<br />
500 ppm thiourea application in maize increased the maize<br />
yield by 18-35 %<br />
Seed priming of sorghum with thiourea (0.1%) and maize<br />
with KH 2<br />
PO 4<br />
for crop establishment and contingent<br />
planning. Seed priming of sorghum with thiourea @ 0.1%<br />
and maize with KH 2<br />
PO 4<br />
@ 2% increased the crop yield by<br />
12-23%.<br />
Combating the dry spell effect through foliar application of<br />
NPK (19:19:19) @ 0.5 % + ZnSO 4<br />
@ 0.5% in maize crop<br />
during the dry spell was popularized and adopted by 25% in<br />
the domain area.<br />
Application of PROM (Phosphate Rich Organic Manure)<br />
@ 30 kg per ha in maize + blackgram (2:2) intercropping<br />
system recorded 16% higher maize grain equivalent yield in<br />
comparison to DAP fertilizer.<br />
A large number of farmers of the zone prepared compost by<br />
the NADEP method and get nutrient-rich organic manure as<br />
compared to the open heap manure system.<br />
Application of 125% recommended N in sorghum improved<br />
the grain yield by 22% with additional net return of Rs.<br />
5957 ha -1 in comparison to the recommended practice in the<br />
domain area.<br />
Application of gypsum @ 120 kg ha -1 in groundnut<br />
enhanced the pod yield by 15% with an additional net return<br />
of Rs. 11674 ha -1 being followed by the dryland farmers in<br />
Bhilwara region.<br />

In Bhilwara district, large number of small and marginal<br />
farmers use Arjia wheel hoe and 2 HP power weeder for<br />
interculture in different crops and saved 30-35% cost and<br />
68-83% time ha -1<br />
Tractor drawn multi-crop planter and interculture implement<br />
(tirri) with slight modification (in rim and tyre of tractor) is<br />
successfully used by the farmers and saves 80% time and<br />
41% cost per hectare.<br />
Tractor drawn intercropping seed drill developed by the<br />
center which made sowing of maize + blackgram (2:2)<br />
paired row system saved 28-35% cost and 65-78% time.<br />

Brief history of the Centre<br />
Indian Council of Agricultural Research (ICAR), New Delhi<br />
sponsored an All India Coordinated Research Project for<br />
Dryland Agriculture in September 1970 located at Hoshiarpur<br />
under the control of Department of Soils, Punjab Agricultural<br />
University, Ludhiana with different operational stations from<br />
time to time. Presently, it is located at Ballowal Saunkhri, earlier<br />
in district Hoshiarpur and since 1990 in district Shahid Bhagat<br />
Singh Nagar. Before the establishment of Zonal Research<br />
Station at Ballowal Saunkhri in 1982, the project was operated<br />
in villages of district Hoshiarpur but subsequently it was shifted<br />
to Ballowal Saunkhri. The ORP centre was established in 1976.<br />
Agro-climatic zone characteristics<br />
AICRPDA centre Ballowal Saunkhri is located in the agroclimatic<br />
Zone-l in the North-Eastern part of the Punjab (agroecological<br />
sub-region 9.1) in the form of 10 to 20 km wide<br />
strip covering an area of approx. 3.929 lakh hectares which<br />
comprises approximately 7.8% of total geographical area of<br />
the State. This zone is located between 30°44′ and 32°32′ N<br />
latitude and 75°52′ and 76°43′ E longitude at an elevation of<br />
300-500 m above mean sea level. The region stretches from<br />
Dhar Kalan block of Pathankot district to Dera Bassi block of<br />
SAS Nagar. The climate of the zone is semi-arid to sub-humid.<br />
The average annual rainfall is 1051 mm. The normal onset of<br />
monsoon is during first week of July and the normal withdrawal<br />
of monsoon is during fourth week of September. The maximum<br />
and minimum temperature during kharif season ranged from<br />
31.9 °C to 40.8 °C and 21.4 °C to 26.2 °C, whereas during rabi<br />
season it varied from 16 °C to 38.9 °C and 2.3 °C to 20.4 °C,<br />
respectively.<br />

Major soil types<br />
The major soil types in the zone are loamy sand to sandy loam.<br />
Major rainfed crops<br />
The major rainfed crops cultivated in the zone during kharif<br />
are maize, blackgram, fodder bajra, sesame and greengram and<br />
during rabi are wheat, raya, taramira, gobhi sarson, toria, lentil<br />
and chickpea. Besides, field crops, vegetables crops such as<br />
ashgourd, cucumber and pumpkin during kharif and vegetable<br />
pea during rabi are also cultivated.<br />
Socio economic characteristics<br />
People of the area are generally poor, illiterate and tradition<br />
bound. They are not conversant with the improved technologies.<br />
The land holdings are small, fragmented and are generally<br />
degraded and poor in productivity. Majority of the farmers in<br />
this region are having holding of less than 2 ha which exist<br />
in small fragmented pieces. The farmers’ capacity to invest is<br />
very limited. The farmers generally do not use inputs needed<br />
for high production, viz., fertilizer, insecticides, pesticides<br />
and weedicides and improved seeds because of (i) uncertainty<br />
about the returns due to crop failure (erratic rainfall), (ii) poor<br />
economic condition and (iii) lack of awareness about improved<br />
technology (extension gaps). In the Kandi area, almost equal<br />
numbers to land holders are landless people who work as daily<br />
paid labourers. Farming as profession even with land holders is<br />
a subsidiary occupation, about 40% of them work at their farms<br />
and others go to cities for earning their livelihood.<br />

Significant achievements<br />
Field experiments under rainfed conditions as per mandates<br />
of AICRPDA were conducted at Regional Research Station<br />
(P.A.U.), Ballowal Saunkhri to study the effect of low till<br />
farming strategies and crop residue management on resource<br />
conservation and improvement of soil quality, improvement<br />
of crop productivity by integrated nutrient management<br />
practices, application of locally available mulch material,<br />
thiourea application, seed priming, intercropping, evaluation<br />
of improved varieties under rainfed conditions, phosphorus<br />
and sulphur management with seed inoculation in chickpea,<br />
rain water management, integrated farming systems, precision<br />
levelling and contingency crop planning for seasonal drought<br />
conditions under rainfed conditions.<br />

A farm pond was developed at AICRPDA centre<br />
Ballowal Saunkhri in 2015 to harvest the rain water from<br />
the catchment area of about 1.8 ha. The farm pond is<br />
trapezoidal in cross section having the storage capacity<br />
of 696 m 3 water. The lining of farm pond has been done<br />
by cement and soil (1:8 ratio) mixture and gravel in 1×1<br />
compartment. The harvested rainwater is lifted using 1<br />
HP solar powered pump. Supplemental irrigation through<br />
micro-irrigation system in maize and okra resulted in<br />
36.8% and 28.0% higher yield over rainfed maize and okra,<br />
respectively. In rabi season harvested water in farm pond<br />
applied judiciously as supplemental irrigation in wheat at<br />
CRI stage gave 41.7% higher yield over rainfed wheat.<br />
Use harvested water for pre-sowing irrigation in case<br />
of deficit seed zone moisture for rabi crops. If seed<br />
zone moisture at sowing is sufficient, one supplemental<br />
irrigation to wheat at crown-root initiation is best. The<br />
irrigation to wheat at large areas was found beneficial over<br />
two irrigations on smaller area. If there is dry spell during<br />
tasseling and pollination phase of maize crop, use harvested<br />
water as life-saving irrigation.<br />
Application of one supplemental irrigation to maize & okra<br />
during dry spell, at CRI stage to wheat and as pre-sowing<br />
irrigation to pea gave 50, 51, 93 and 100% respectively,<br />
higher yield over rainfed conditions.<br />
Cropping systems<br />
Crops and cropping system available for the region: Maize<br />
was found to be most suitable and assured crop during kharif<br />
season. In case of sandy soils with low moisture holding<br />
capacity pearl millet for fodder purpose performed better than<br />
maize. Performance of rabi crops was better after summer<br />
fallow than after maize. The combined yield of two crops per<br />
year was always considerably higher than that of a single rabi<br />
crop. Maize-wheat sequence was best in years of favourable<br />
rainfall whereas maize-wheat+gram sequence performed better<br />
in low rainfall years. Sunflower and safflower can be cultivated<br />
successfully under rainfed conditions.<br />
Green manuring and use of leguminous crops: The yield of rabi<br />
crops was better after green manuring rather than after maize<br />
crop or after summer fallow. Growing of short duration legume<br />
crop of moong gave an additional yield of 3 to 4 q/ha and proved<br />
even better than green manuring. Green manuring with 40 days<br />
old sunhemp crop was better than that of 30, 50 or 60 days old<br />
crop in terms of wheat yield.<br />
Inter-cropping<br />
●<br />
Sowing of 2-4 rows of pearl millet around maize fields<br />
saved maize crops from animal and human damage, worked<br />
as wind break and provided fodder for livestock.<br />
●<br />
●<br />
Wheat + raya in rows (One row of raya after every 12 rows<br />
of wheat) proved more remunerative compared to wheat<br />
alone.<br />
Intercropping of greengram/blackgram between two rows<br />
of maize spaced 50 cm gave higher maize equivalent yield<br />
as compared to sole maize.<br />
● Intercropping of green gram in paired row of maize (30/60<br />
cm) resulted in highest maize equivalent yield followed by<br />
blackgram.<br />
●<br />
Raya intercropping in wheat and gram at 3.0 m apart in<br />
north-south direction and in lentil at 2.0 m apart provided<br />
additional income and covered the risk of crop failure under<br />
rainfed conditions.<br />
Strip-intercropping<br />
●<br />
●<br />
Cultivation of maize and cowpea on 1% slope gave<br />
significantly higher yield (3331 kg/ha), net returns (Rs.23202<br />
/ha), BC (1.75) and WUE (6.22 kg/ha/mm) than 2% and 3%<br />
slope. A strip intercropping system with maize strip width<br />
of 4.8 m and cowpea strip width of 1.2 m (4.8:1.2) gave<br />
significantly higher maize equivalent yield (MEY) (3862 kg/<br />
ha) over maize: cowpea strip width of 3 m: 3 m, 1.2 m: 4.8 m<br />
and sole cowpea with a respective increase of 8.9, 17.8 and<br />
32.8 per cent with highest LER (1.22), net returns (Rs.28428/<br />
ha) and WUE (7.18 kg/ha/mm -1 ).<br />
Strip-intercropping of maize in 6 m and blackgram in 2.4 m<br />
wide strips gave 9.3% higher yield over sole blackgram and<br />
10.9% over sole maize.<br />
Double cropping<br />
●<br />
●<br />
●<br />
●<br />
Soils of high and medium water holding capacity were<br />
suitable for maize- wheat system.<br />
If sufficient moisture is available after kharif crop, raya in<br />
rabi is most profitable.<br />
On sandy soils with low water holding capacity, summer<br />
fallow was better than double cropping.<br />
Total productivity of cropping sequence was higher in<br />
blackgram-raya, maize-raya and maize-chickpea sequence<br />
or compared to traditional maize-wheat sequence. Thus,<br />
cultivation of raya and chickpea was found to be more<br />
profitable when grown after blackgram maize crops<br />
respectively.<br />
Triple cropping systems<br />
●<br />
Maize-toria-late sown wheat cropping system resulted in<br />
maize equivalent yield of 10616 kg/ha which was 18.3<br />
higher than maize-wheat cropping system.<br />
RTCPs identified for early/midseason/terminal droughts<br />
Based on the experiments conducted at the station and on the<br />
farm the following real time contingency measures have given<br />

like greengram, blackgram and sesame.<br />
If monsoon onset is delayed by 30 days sow greengram for<br />
grains or pearl millet for fodder.<br />
Real time contingency measures for rabi cropping<br />
Scenario I: Low soil moisture at sowing<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Placing the seed in the moist soil zone ensures uniform<br />
germination of the crop.<br />
Sowing of wheat at wider row spacing of 30 cm is better<br />
than 22-25 cm.<br />
Chickpea, linseed and rapeseed and mustard perform better<br />
than wheat in low soil moisture.<br />
Sowing of chickpea after seed priming in molybdenum<br />
solution (1 g molybdenum per 2 litres of water) ensures<br />
better germination and higher yield of the crop.<br />
Sowing of wheat crop after soaking seed in thiourea<br />
solution (1 g thiourea per litre of water) results in uniform<br />
germination and higher yield.<br />
● Late sown varieties of wheat like (PBW 752 and PBW 771)<br />
can be sown in December or very late sown wheat variety<br />
(PBW 757) may be sown in January after the receipt of<br />
winter rains.<br />
Scenario II: Failure of winter rains<br />
●<br />
●<br />
Apply supplemental irrigation from the harvested rain water<br />
to save the crop.<br />
Application of foliar spray of thiourea solution (1g thiourea<br />
per litre of water) to wheat at maximum tillering and booting<br />
stage increases grain yield.<br />
Nutrient management<br />
Nutrient management in kharif crops<br />
Maize:<br />
● In Sandy loam soils having medium water storage, 80 kg N/<br />
ha is optimum whereas for loamy sand soils with low water<br />
storage 40 kg N/ha is optimum.
●<br />
●<br />
●<br />
●<br />
●<br />
The response to applied P was observed only for soils testing<br />
low in available P and that too only up to 20 kg P 2<br />
O 5<br />
/ha .<br />
All source of N in two splits i.e. ½ at sowing and ½ at knee<br />
high stage proved slightly better than full N at sowing.<br />
Foliar application of N was not beneficial.<br />
Application of 10 t/ha FYM increased maize yield by about<br />
3 q/ha but the effect was observed in low N application only.<br />
Application of crop residues reduced maize yield by 50% as<br />
compared to control. During initial two years, application<br />
of wider C:N ratio plant residues alone (maize stover and<br />
wheat straw) showed depressing effect but during 3 rd year<br />
onwards the response was encouraging.<br />
Equal yields were obtained with 100% inorganic N and<br />
50% organic + 50% inorganic N.<br />
● Application of 40 kg K 2<br />
O/ha resulted in 18.6 and 10.7%<br />
higher grain yield of maize over control and 20 kg K 2<br />
O/ha,<br />
respectively. Magnesium sulphate application @ 45 kg/ha<br />
improved yield of maize.<br />
Fodder crops:<br />
●<br />
●<br />
Bajra and fodder sorghum responded to N up to 50 kg/ha.<br />
Napier bajra hybrid responded up to 50 kg/ha applied after<br />
each cutting.<br />
Nutrient management in rabi crops<br />
Wheat:<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Early tall wheat varieties line C-306 responded up to 30 kg<br />
N/ha only in loamy sand soils.<br />
High yielding late varieties responded up to 80 kg N/ha in<br />
medium storage soils and up to 120 kg N/ha in soils of high<br />
moisture storage.<br />
Different sources of N like urea, calcium ammonium nitrate<br />
and ammonium chloride were equally effective however<br />
ammonioum chloride was slightly inferior in performance.<br />
Application of half of recommended N as basal and<br />
remaining half with winter rains proved economical.<br />
Early tall wheat varieties were not responding to P<br />
application but late dwarf varieties responded up to 20 and<br />
40 kg P 2<br />
O 5<br />
in loamy sand and sandy loam soils respectively.<br />
Chickpea:<br />
●<br />
●<br />
●<br />
●<br />
Response of gram to P application on soils with 16 kg<br />
available P 2<br />
O 5<br />
/ha or less, was up to 20 kg P 2<br />
O 5<br />
/ha.<br />
In Wheat + gram mixture, response to N was observed up<br />
to 60 kg N/ha in clay loam and sandy loam soils, whereas it<br />
was up to 20 kg N/ha in loamy sand soils.<br />
Seed priming of gram with molybdenum increased seed<br />
yield up to 0.5 g/litre of water compared to control.<br />
Application of P+S to rainfed gram gives highest seed yield.<br />
●<br />
Lentil:<br />
●<br />
●<br />
Seed inoculation with Rhizobium gave better yield and<br />
economic returns than control.<br />
Seed inoculation with Rhizobium culture and fertilizer<br />
application of N @12.5 kg and P 2<br />
O 5<br />
@ 20 kg/ha gave higher<br />
crop yields.<br />
Green manuring with green gram along with recommended<br />
fertilizers gave highest yield.<br />
Oilseeds:<br />
●<br />
●<br />
Application of 50 kg N/ha to sole toria , 75 kg N/ha to sole<br />
gobhi sarson is optimum.<br />
For toria-gobhi sarson intercropping system, application of<br />
30 kg N/ha to toria and 50 kg N/ha to gobhi sarson is better.<br />
Maize-wheat cropping system:<br />
● In maize-wheat cropping system application of FYM @10<br />
t/ha benefitted both maize and wheat crop in normal rainfall<br />
years.<br />
●<br />
●<br />
In maize-wheat sequence when FYM is applied to maize,<br />
a saving of 50% N can be made in case of the succeeding<br />
wheat crop.<br />
Wheat crop responded up to 20 kg P 2<br />
O 5<br />
/ha but there was<br />
no residual effect of P applied to maize on wheat. Long<br />
term application of P to wheat showed its residual effect on<br />
maize crop.<br />
Tillage and nutrient management<br />
In maize-wheat rotation, 50% conventional tillage + interculture<br />
+ chemical weed control was at par with conventional<br />
tillage+interculture, thus saving two tillage operations. Among<br />
N sources, application of 100% N through urea gave best results.<br />
Permanent manurial trial<br />
In maize-wheat cropping system, application of 100%<br />
recommended NPK + FYM @ 10 t/ha gave highest yield of<br />
maize and wheat which was significantly higher over all other<br />
treatments.<br />
Crop improvement/evaluation of drought tolerant varieties<br />
●<br />
●<br />
Maize: Local varieties sown earlier were maturing earlier<br />
that resulting in more residual soil moisture and better rabi<br />
crop yields but these were replaced with composites and<br />
hybrids because of their low yield potential. Prominent<br />
composite varieties were Megha and Kesari whereas<br />
prominent recommended hybrids were Prakash, JH-3459<br />
and PMH-2. Newly developed composites are JC12 & JC4.<br />
Bajra: HB-1 was best variety in seventies, followed by<br />
PHB47, PCB8 and PHB10, PCB15 and PCB138 in eighties<br />
and nineties. In the beginning of twenty first century PCB164<br />
and PHB 2168 were recommended for grain purpose and<br />
FBC16 and PHBF-1(hybrid) for fodder purpose.<br />

●<br />
●<br />
●<br />
●<br />
●<br />
Sesamum: Earlier sesamum IVI 24 was best but later on,<br />
TC289, RT346, Punjab Til No. 1 and Punjab Til No.2 were<br />
recommended.<br />
Blackgram mash: Mash 1-1 in seventies, Mash 48, then<br />
Mash 338 and Mash 114 were recommended. KUG 882 is<br />
recently recommended for the farmers of the domain area.<br />
Greengram moong: ML 131 and ML 267, ML613, were<br />
earlier varieties which were replaced by ML818, ML 2056,<br />
ML 1808 and PAU911 under rainfed conditions.<br />
Wheat: In late seventies under low rainfall conditions tall<br />
variety C306 was best but in normal rainfall years dwarf<br />
varieties WL 357, WL 410 and PBW 2265 were better.<br />
Later on PBW 175, PBW 299, PBW 644 and PBW 660 were<br />
recommended for cultivation. Late sown wheat varieties<br />
PBW 752, PBW 757 & PBW 771 are found promising for<br />
late sowing in December after receipt of rains.<br />
Barley: In recent years PL426, PL56 and PL419 were found<br />
better than local varieties.<br />
Gram: Till early eighties C235 was best variety. Later on<br />
PBG-1, PBG-5 and PBG-7 were recommended.<br />
Lentil: Earlier L 9-12 was best but later on LL699 and<br />
LL931 were recommended.<br />
Raya: Earlier RL18 and T59 were significant but later on<br />
PBR91, PBR97 and RLM619 were tested and released.<br />
Taramira: TMLC-2 variety of taramira was recommended.<br />
Linseed: LC54 variety of linseed performed well in dry land<br />
conditions.<br />
Crops for animal damage prone areas:<br />
●<br />
●<br />
Safflower strains ISF-1, SPP-A-129 and MKH-9 were<br />
better than local check Bhima. Because of thorns this crop<br />
is not damaged by wild animals.<br />
Sesamum during kharif season and taramira during rabi<br />
season are suitable alternate crops as they perform better<br />
than other crops in animal damage prone areas.<br />
Energy management/ farm mechanization<br />
In maize-wheat cropping system, conventional tillage (Disc<br />
harrow + cultivator + planking) resulted in 15.0 and 5.0% higher<br />
grain yield of maize and wheat over rotavator.<br />
Alternate land use system<br />
Agroforestry: Planting of Kikar (Acacia nilotica) and Safeda<br />
(Eucalyptus spp) in blocks at 3x5 m spacing performed best.<br />
Under these trees in kharif season fodder crops and in rabi<br />
season oilseed crops can be grown.<br />
Agro-horticulture<br />
●<br />
Amla, Galgal, Ber, Guava and Mango can be grown in<br />
rainfed kandi region. These trees can be planted at 7.5 x 7.5<br />
m distance.<br />
Manmohanjit Singh et al.<br />
82<br />
●<br />
●<br />
●<br />
Up to the age of 4 years of these trees, intercropping with<br />
leguminous crops can be done.<br />
Grasses could also be grown successfully as intercrops in<br />
these orchards.<br />
Fruit based agri-horticulture system like amla + blackgram,<br />
guava+blackgram during kharif and amla + taramira, guava<br />
+ taramira, amla + lentil and guava + lentil during rabi were<br />
better than annual crops.<br />

If field is vacated due to early maturity of crop, then<br />
cultivate the field to conserve moisture for rabi crops.<br />
Harvest maize crop at physiological maturity in order to<br />
conserve soil moisture by immediately ploughing and<br />
planking the field.<br />
With sufficient soil moisture, toria or vegetable pea can be<br />
sown in mid-September as sole crop or toria+ gobhi sarson<br />
can be sown as intercrop (1:1)<br />
Late sown wheat varieties (PBW 752 and PBW 771) can be<br />
sown in December or very late sown wheat variety (PBW<br />
757) after the harvest of toria and pea<br />
For rabi planning<br />
a. Suggested crops and varieties for delayed season<br />
Sometimes due to the early withdrawal of monsoon soil moisture<br />
is not adequate for sowing, under such conditions wheat can be
sown after the receipt of winter rains in December. Under this<br />
situation, recommended wheat varieties are PBW 752 and PBW<br />
658 can be sown.<br />

Landshaping was done by most of the farmers in Hoshiarpur,<br />
SBS Nagar, Pathankot and Roopnagar districts of Kandi<br />
region. This technology has already been adopted by the<br />
majority of the farmers’ in the domain area.<br />
Summer ploughing is adopted by 45 per cent of farmers in<br />
domain of the AICRPDA centre, Ballowal Saunkhri. Further<br />
extension efforts by line departments and government<br />
schemes can spread this technology on a larger scale in<br />
farmers’ fields.<br />
The hoeing and holding technique were used in most of the<br />
area under maize cultivation in Kandi region and presently<br />
covers over 60% area in the domain districts. Extension<br />
efforts through demonstrations and other government<br />
schemes can push this technology in farmers’ fields along<br />
with assistance from the KVKs in the domain of AICRPDA<br />
centre.<br />
The technique of moisture conservation by ploughing and<br />
planking is practiced by 60 per cent farmers in domain<br />
districts of AICRPDA centre in Kandi region. Extension<br />
efforts through demonstrations and other government<br />
schemes can push this technology in farmers’ fields along<br />
with assistance from the KVKs in the domain of the<br />
AICRPDA centre.<br />
The technique of moisture conservation by locally<br />
available vegetative mulch is adopted on a limited scale<br />
by the farmers as it requires considerable human labour<br />
for collection and spreading and there is also difficulty in<br />
spreading the material in standing crop. Extension efforts<br />
through demonstrations and other government schemes can<br />
push this technology in farmers’ fields along with assistance<br />
from the KVKs in the domain of the AICRPDA centre.<br />
The technique of moisture conservation by in-situ raised<br />
mulch is adopted on a limited scale by the farmers.<br />

The area under sugarcane is increasing in Kandi region.<br />
Presently it is cultivated in ‘beet’ area of Hoshiarpur<br />
districts. Extension efforts through demonstrations and<br />
other government schemes can push this technology in<br />
farmers’ fields along with assistance from the KVKs in the<br />
domain of the AICRPDA centre.<br />
Sowing across the slope has shown a marked increase in the<br />
yield of crops as compared with the sowing along the slope<br />
method. So, most of the farmers cultivating maize, wheat<br />
and other crops on undulating fields sow their crops across<br />
the slope. Further upscaling can be done through extension<br />
efforts by line departments and KVKs.

The technology of V-ditch method of planting for<br />
horticultural and forestry plants on sloppy land can be<br />
upscaled through demonstrations by line departments and<br />
KVKs situated in the domain of the AICRPDA centre.<br />
The technology of constructing water harvesting pond is<br />
new to the farmers and only few such water harvesting<br />
structures are available with the individual farmer. However,<br />
community water harvesting ponds on village panchayat<br />
land are available in the Kandi region. Large-scale adoption<br />
can be achieved with the government support by giving<br />
subsidy on solar pump and construction cost.<br />
After introduction of Makowal type water harvesting<br />
system there was 14.4%, 5.9% and 3.8% improvement<br />
due to crops, dairy farming and agroforestry, respectively.<br />
After its success in village Makowal, this water harvesting<br />
structures were replicated in about 110 other places in the<br />
Kandi region.<br />
Farmers in the domain area are adopting this technology as<br />
it controls soil erosion and conserves soil moisture for the<br />
succeeding rabi crops. Extension efforts through exposure<br />
visits to the farmer fields adopting this technology by state<br />
agriculture department and KVKs will further increase the<br />
adoption of vegetative barrier on field bunds.<br />
The adoption of this technology will increase the wheat<br />
yield in rainfed areas and reduce the risk of crop failure<br />
under adverse weather conditions. The technology is widely<br />
accepted by the farmers and can be further upscaled through<br />
trainings/demonstrations by line departments and KVKs.<br />
One row of maize is sown on the side of the ridge 6-7 cm<br />
above the base at 60 cm x 20 cm. Sowing on ridges helps<br />
to avoid the adverse effect of excess rainfall, particularly at<br />
seedling emergence during kharif season. The furrows act<br />
both as drainage channels during high rainfall events and<br />
as moisture conservation furrows when rainfall is low. The<br />
moisture stored in the soil profile is utilized by existing and<br />
succeeding crops during moisture deficit conditions.<br />
Ridge sowing of maize is a useful climate resilient<br />
technology under rainfed conditions as furrows act both<br />
as drainage channels during high rainfall events and as<br />
moisture conservation furrows when rainfall is low. It gives<br />
higher yield of maize and wheat crop than flat sowing. The<br />
extension efforts through FLDs through different State<br />
Agriculture Department schemes as well as KVKs can<br />
promote this technology to benefit the farming community.<br />
Conservation furrow method of planting maize is a climate<br />

efforts through FLDs through different State Agriculture<br />
Department schemes as well as KVKs can promote the strip<br />
cropping to benefit the farming community.<br />
The farmers appreciated the advantages of sowing maize at<br />
wider row spacing (45 and 60 cm) as compared to existing<br />
practice (30 cm), though there was no increase in maize yield<br />
due to wider row spacing. The farmers however adopted<br />
this practice due to the ease of intercultural operations and<br />
less requirement of labour. The row spacing of 60 cm is<br />
relevant in the present time. So, it needs to be expanded in<br />
the domain districts with the support of line departments<br />
and KVKs in the domain of the AICRPDA centre.<br />
The area under PBW 660 is increasing in Kandi region<br />
and presently this variety cover about 30 % of the total<br />
area under rainfed wheat in Shahid Bhagat Singh Nagar,<br />
Roopnagar and Hoshiarpur districts. Further extension<br />
efforts through FLDs, NFSM, ATMA, RKVY and other<br />
government schemes can popularize this variety among<br />
farmers.<br />
The area under FBC 16 is increasing in Kandi area and<br />
presently covers about 20% of the total area under pearl<br />
millet (fodder) in Shahid Bhagat Singh Nagar and Hoshiarpur<br />
districts. Further extension efforts through FLDs, NFSM<br />
and other government schemes can popularise this variety<br />
among farming community.<br />
Late sown wheat varieties have increased the cropping<br />
intensity in the rainfed areas as they can be sown after<br />
the harvest of toria and vegetable pea. Further extension<br />
efforts through FLDs, NFSM, ATMA, RKVY and other<br />
government schemes can popularize this variety among<br />
farmers.<br />
Potassium and magnesium application in rainfed maize is<br />
demonstrated in N<strong>ICRA</strong> villages which resulted in higher<br />
yield than farmer practice. It needs to be demonstrated and<br />
up scaled further with the support of line departments and<br />
KVKs.<br />
The technology of potassium nitrate spray during dry<br />
spells application to maize is a promising technology but<br />
is adopted on a limited scale by the farmers of the domain<br />
area. It needs to be demonstrated on a large scale through<br />
demonstrations by line departments and KVKs to make it<br />
acceptable among the farmers.<br />
About 50 per cent farmers in adopted village of SBS<br />
Nagar and Hoshiarpur districts currently use this seed cum<br />
fertilizer drill. Large scale adoption can be achieved by<br />
more demonstrations by KVKs and line departments.<br />
Laser land levelling not only conserves moisture in<br />
rainfed conditions but also improve the efficiency of other<br />
agricultural inputs. This also results in uniform maturity of
●<br />
●<br />
the crop, better quality and higher yield. Keeping in view<br />
the benefits of laser land levelling technology farmers of<br />
the Kandi region have readily adopted this technology and<br />
it needs to be further promoted in a big way through Govt.<br />
and Non-Govt. organizations.<br />
The area under sesame is less than 1% in the domain<br />
region but farmers are now shifting from maize to sesame<br />
cultivation in the domain area due to lower cost of cultivation<br />
and higher returns besides less damage by wild/stray cattle.<br />
Ash gourd has become the main cash crop for kharif season<br />
in the Beet area. Farmers are getting very good price in<br />
the market which has increased the economic status of the<br />
farmers. Further upscaling can be done through extension<br />
efforts by line departments, KVKs, besides taking up seed<br />
production. This would reduce the menace of the wild<br />
animals in the region to a great extent.<br />
Way forward<br />
AICRPDA centre, Ballowal Saunkhri has been working since<br />
1970. During this period there has been tremendous progress<br />
in all fields of agriculture. The farmers of the region have been<br />
benefitted from the technologies developed by the centre. The<br />
research outcomes have been transferred to the farmers of the<br />
region which resulted in improvement in rural livelihood in<br />
the region. However, during the last 5-7 years, the agriculture<br />
in the region has become vulnerable to the factors like climate<br />
change, increased damage of crops by wild animals, etc. The<br />
centre has given recommendations to the farmers based on the<br />
research carried out at the centre on preparedness and real time<br />
contingent measures to deal with weather aberrations. Also, the<br />
alternate crops tolerant to wild animal damage are tested and are<br />
being recommended to the farmers of the region.<br />
New challenges are being faced by the farmers of the region<br />
because of changing climatic scenario and damage of crops by<br />
wild animals. The centre is working for the development of<br />
the technologies suitable under aberrant weather conditions.<br />
The technologies being generated at this centre are also having<br />
relevance in the Kandi region of adjoining states like Himachal<br />
Pradesh. The rainfed crop varieties developed at the centre<br />
are being adopted by the farmers of that region also. Now a<br />
close linkage has been developed with research and extension<br />
system of these adjoining state agricultural universities so that<br />
technologies developed by AICRPDA centre are disseminated<br />
to these regions also in the nation’s interest. So it will be in the<br />
interest of farming community of Kandi region if the AICRPDA<br />
main centre continues to remain at RRS, Ballowal Saunkhri.<br />
The integrated farming system approach for judicious use of<br />
natural resources under rainfed and limited water conditions<br />
needs to be tested. As the scarcity of water is increasing even<br />
in the irrigated regions, the technologies developed under this<br />
project at the centre shall have relevance in those situations<br />
also. The farmers’ participatory research component needs to be<br />
enhanced for developing relevant technologies and to get benefit<br />
from the ITK of the farmers.<br />

Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture centre was initiated at Samba in 1970-71. In 1977<br />
it was shifted to its present location at Rakh Dhiansar. The<br />
AICRPDA sub-centre came under the control of SKUAST-J&K<br />
in 1982 and after establishing a separate Agricultural University<br />
for the Jammu region, centre has since operated under the<br />
reigns of Sher-e-Kashmir University of Agricultural Sciences<br />
and Technology of Jammu (SKUAST-Jammu) in 1999. The<br />
AICRPDA, Rakh Dhiansar sub-centre is situated at a latitude<br />
of 32° 39’ North and longitude of 74° 53’ East at an elevation<br />
of 332 m above mean sea level. The location of the center<br />
represents the true Kandi (sub-montane) belt and comprising<br />
parts of Samba, Jammu, Kathua and Udhampur districts of<br />
Jammu province.<br />
Agro-climatic zone characteristics<br />
The plains and outer hills of lower Himalayas in Jammu province<br />
(Jammu, Samba, parts of Kathua, Reasi and Udhampur districts)<br />
are grouped in sub tropical zone. The altitude ranges from 215 to<br />
360 m above MSL. The area under this region represents fringes<br />
of level lands, in continuation with the Punjab state plains and<br />
touches the Jammu hills. The climate of the zone is humid sub<br />
tropical. The mean annual rainfall of the zone is 1156.5 mm<br />
out of which 75 to 80% rainfall is received during South-West<br />
monsoon. The normal onset of monsoon is 27 th June + 7 days<br />
and the normal withdrawal is experienced during third week of<br />
September. The mean annual rainfall of the zone (1156.5 mm) is<br />
received in 53 rainy days. The average seasonal rainfall during<br />
kharif (June-September) is 866.0 mm and the average seasonal<br />
rainfall during rabi (October-April) is 290.5 mm. In the recent<br />
past, the domain area has experienced dryspells during the month<br />
of September (36 SMW to 48 SMW) due to early cessation of<br />
monsoon which coincided with the grain filling/maturity stage<br />
of kharif crops (terminal drought). This dryspell usually extends<br />
upto November (36 SMW to 48 SMW) due to the late receipt<br />
of winter rains which result in delayed sowing of rabi crops.<br />
The average maximum and minimum temperatures during<br />
kharif crop season is 34.8 0 C (22 SMW to 26 SMW) and 23.7 0 C<br />
while during rabi season is 24.4 0 C and 10.5 0 C (01 SMW to 05<br />
SMW), respectively. June is the hottest and January remains the<br />
coldest month. With respect to shifts in climate within the agroclimatic<br />
zone, it is being observed that there is a small shift in<br />
the onset of monsoon beyond normal (27th June + 7 days) and<br />
similarly, a shift is also being observed in winter rains received<br />
through Western Disturbances (WD) from October/November<br />
to December/ January.<br />

Major soil types<br />
The major soil types in the agro climatic zone is categorized into<br />
6 major groups:<br />
1). Brown forest soils are in parts of Kathua, Udhampur, Doda,<br />
Poonch, Rajouri, Districts; 2). Degraded or grey brown podzolic<br />
soils occur in parts of Baderwah, Ramnagar and Poonch districts<br />
; 3). Red and yellow podzolic soils occur in parts of Udhampur,<br />
Kathua, Rajouri and Poonch; 4). Hill or mountain forest soils are<br />
sandy loam to loamy in texture. They occur at lower elevations<br />
and have 32-41% water holding capacity. 5). Lithosols occur<br />
on steep slopes in the forest hills of 400 to 600 meters above<br />
sea level in Jammu, Udhampur, Kathua, Rajouri, and Poonch<br />
districts. They belong to great group Ustorthents and 6).<br />
Alluvial soils cover plains of Kathua, Jammu Rajouri, Poonch,<br />
Udhampur districts. They are situated in the flood plains of Ravi<br />
and Chenab rivers and their tributaries.<br />
Major crops<br />
The major rainfed crops cultivated in the zone during kharif are<br />
maize, blackgram, greengram, cowpea, pearl millet and sesame,<br />
during rabi are wheat, mustard, gobhi sarson, chickpea, lentil<br />
and barley.<br />

●<br />
Application of integrated use of inorganic and organic<br />
fertilizers, i.e., FYM 10 t/ha + 40 N kg/ha and Leucaena<br />
leucocephala (Subabul) leaves 5 t/ha + 40 kg N/ha proved<br />
to be the best if the organics are applied in the soil about<br />
2 weeks before sowing of maize crop in maize-wheat<br />
cropping sequence.<br />
Application of integrated use of inorganic and organic<br />
fertilizers, i.e., 50% Recommended NPK + 50% N (FYM)<br />
and 50% Rec. NPK + 50% N (crop residues) and the<br />
organics are to be applied in the soil about 2 weeks before<br />
sowing of maize crop under cereal-oilseed system. There<br />
is a pronounced residual effect of the organics in the<br />
succeeding gobhi sarson crop.<br />
Application of 75% N (inorganic) +25% N vermicompost<br />
recorded highest pearl millet mean grain yield of 26<strong>37</strong> kg/<br />
ha with 70% increase over control.<br />

Tillage and nutrient management practices<br />
●<br />
Treatment with 50% conventional tillage + herbicide<br />
(atrazine @ 1.5 kg/ha) + interculture operations along<br />
with 100% inorganic fertilizer (N: P 2<br />
O 5<br />
:K 2<br />
O (60:40:20))<br />
results in increasing the grain yield in maize as compared to<br />
farmers’ practice (conventional tillage + two hand weeding<br />
with khurpi + no herbicide + use of N and P only).<br />
Agroforestry systems<br />
●<br />
●<br />
Growing mixed fodder (maize + cowpea + pearl millet)<br />
in the alleys of Leucaena leucocephala is found to be<br />
remunerative as this land use system recorded higher<br />
maize equivalent yield (MEY), sustainable yield index<br />
(SYI) and rain water use efficiency (RWUE) as compared<br />
to other land use systems in the rainfed sub-tropics of<br />
lower Shiwalik foothills of Jammu and Kashmir.<br />
The maize crop recorded grain yield of 2595 kg/ha in<br />
treatment Agri-horti-silvi-pastoral System (Guava + Melia<br />
+ Setaria Spp.+ Maize- Gobhi sarson) wherein the maize<br />
crop was sown in the alleys formed by Horti-Silvi-Pastoral<br />
component. However in rabi, the wheat crop recorded grain<br />
yield of 4226 kg/ha in treatment Agri-Horti-Silvi-Pastoral<br />
system (Guava + Melia + Setaria Spp.+ Black gram - wheat)<br />
wherein the wheat crop was sown in the alleys formed by<br />

●<br />
●<br />
During kharif, under horti-silvi-pastoral system components<br />
viz., Guava Var. L-49 -Melia Spp - Setaria Spp. may be<br />
taken to rainfed conditions of Jammu. However, maize and<br />
blackgram should be sown in the alleys formed by hortisilvi-pastoral<br />
components. The maize and blackgram sown<br />
in the alleys should be given 60:40:20 and 16:40:0 kg N, P<br />
and K/ha, respectively.<br />
During rabi, wheat and gobhi sarson may be taken as alley<br />
crops under horti-silvi-pastoral system with 100:50:25 and<br />
50:30:15 kg N, P and K/ha, respectively.<br />
Conservation furrows should be created along side of the<br />
tree rows to drain the field runoff and store it in the furrows<br />
for long retention of soil moisture and its utilization by the<br />
Guava, Melia and Setaria grass.<br />
Technologies upscaled in convergence with various<br />
programmes<br />
The research technologies recommended for inclusion in the<br />
package of practices of SKUAST-Jammu were discussed<br />
during the Zonal Research and Extension Advisory Committee<br />
meeting (ZREAC) from time to time with the officers such as<br />
Director of Agriculture and allied departments for their further<br />
dissemination amongst the farmers of domain area by way of<br />
integrating the same into State/District Action Plans.
Impact of technologies<br />
The higher maize yield was obtained in continuous trenching<br />
method of in-situ moisture conservation followed by strip<br />
trenching method. The maximum B:C ratio of 2.42 was obtained<br />
in continuous trenching method in maize while maximum B:C<br />
ratio of 3.08 in wheat. Higher maize equivalent yield (MEY)<br />
was obtained in paired rows of maize with 2 rows of cowpea<br />
(2610 kg/ha) with mean LER values of 1.23 and highest<br />
RWUE as well as B:C ratio values of 3.40 kg/ha-mm and 1.83,<br />
respectively. Planting two rows of cowpea as intercrop in paired<br />
rows of maize in additive series. Intercropping of cowpea with<br />
maize is gaining popularity among the rainfed farmers of the<br />
kandi region of Jammu. This technology has been adopted by<br />
more than 70 farmers with a horizontal spread over an area of<br />
about 4.5 ha area. Sowing of maize using maize planter resulted<br />
in maximum benefit cost ratio of 2.59 followed by line sowing<br />
with liner and broadcasting with B:C ratio of 2.10 and 2.01,<br />
respectively. The technology has been extensively demonstrated<br />
in the farmer’s fields. Sowing of wheat by Seed cum fertilizer<br />
drill (improved practice) resulted in maximum benefit cost<br />
ratio of 3.19 followed by line sowing with liner and sowing by<br />
broadcasting (farmers’ practice) with B:C ratio of 2.57 and 2.34,<br />
respectively. The technology has been extensively demonstrated<br />
in the farmer’s fields. Among the alternate land use system,<br />
mixed fodder-gobhi sarson grown in the alleys of aonla trees<br />
under agri-horti-pastoral system followed by mixed fodderwheat<br />
grown in the alleys of Leucaena trees under agri- silvipastoral<br />
system were found to be most remunerative systems<br />
as compared to all other systems. The technology has been<br />
demonstrated at farmer’s field and appreciated by the farmers.<br />
Way forward<br />
The AICRPDA, Rakh Dhiansar Center will focus on mitigating<br />
land degradation by adopting practices that improve soil health,<br />
sustainable water management and promoting diversified<br />
sustainable production systems that are suited for the agroecosystems<br />
and promoting a holistic approach to risk reduction<br />
and climate resilience of farms and landscape. Evaluation of<br />
suitable varieties of millets, legumes, oilseeds, dryland medicinal<br />
and horticultural crops will contribute to efficient and successful<br />
crop production. More focus would be on development of<br />
integrated farming systems (IFS), which synergistically integrate<br />
two or more enterprises (crops, horticultural crops, livestock,<br />
poultry, apiculture, and mushroom cultivation) that can offer<br />
improved income, resilience, and soil carbon sequestration<br />
potential.<br />

Brief history of the Centre<br />
Agra Centre of All India Co-ordinated Research Project for<br />
Dryland Agriculture, located at Agra under the jurisdiction of<br />
Raja Balwant Singh College, Bichpuri Agra, formerly known<br />
as B.R College and was initiated in 1970 as a sub-centre at<br />
same location. The Agra centre of AICRPDA represents Southwestern<br />
semi-arid region of Uttar Pradesh covering 8 districts,<br />
i.e., Agra, Firozabad, Mainpuri, Hathras, Aligarh, Mathura, Etah<br />
and Kansi Ram Nagar with geographical area of 22424 Km 2 ,<br />
accounting for 7.62% area of the state.<br />
Agro-climatic zone characteristics<br />
The climate is semi-arid sub-tropical characterized with dry hot<br />
summer months and severe cold in winter months. Out of the<br />
total annual average rainfall of 664.5 mm, south-west monsoon<br />
contributes 88% while 9.0% from north-east monsoon and 2.5%<br />
during summer. The normal onset of south-west monsoon is<br />
during first week of July and withdrawal is during third week<br />
of September. The dry spells during crop season had been<br />
experienced in July, August and September coinciding with<br />
germination, vegetative and grain formation stags of the major<br />
rainfed crops. In summer, temperature raises upto 48 0 C with<br />
desiccating winds. The potential-evapo-transpiration (PET) is<br />
about 1850 mm with an average of 5.05 mm/day, a maximum<br />
of 10.7 mm/day in June and a minimum of 2.13 mm/day in<br />
January. Winter is short (end of November to February). The<br />
temperature is as low as 0.5 0 C or occasionally 0 0 C at the peak of<br />
winter in the month of January. The normal onset of monsoon<br />
during south-west monsoon is during third week of June while<br />
withdrawal is during first to second week of October.<br />

Dryland agriculture problems<br />
The problems related to domain districts are as enlisted below<br />
Rainfall, soil and land management<br />
●<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Rainfall pattern of area is highly erratic, crops may suffer<br />
from moisture stress at any stage of growth in each and<br />
every year, resulting in poor yields.<br />
Soils of the region are inceptisols, which are sandy loam to<br />
loamy sand with pH of 7.9 to 8.6, low in organic matter, low<br />
in fertility status and deficient in micronutrients,<br />
Ground water table is depleting at an alarming rate, mainly<br />
due to over exploitation of ground water, which is saline to<br />
alkaline in nature commonly applied in cereals crops during<br />
rabi season. Ground water of the area is saline in nature and<br />
about 70% ground water is not suitable for growing pulses<br />
and oilseeds.<br />
Numbers and area of natural reservoirs /community tanks<br />
decreasing day by day, which are the major contributors of<br />
ground water recharge.<br />
Small land holding size and scattered ownership, farmers<br />
cannot individually adopt rain water management<br />
techniques with special reference to farm pond technology.<br />
Lack of accurate forecasting of rains.<br />
Crop production<br />
●<br />
●<br />
Mostly varieties developed for irrigated conditions are also<br />
recommended for dryland conditions.<br />
Most of the varieties performed better in normal season,<br />
but they are not suitable for aberrant weather conditions<br />
especially during late kharif season.<br />
Socio-economic<br />
●<br />
Unavailability of agricultural inputs at proper time.<br />
94
● Unavailability of equipment suitable for different<br />
agricultural operations for fragmented holdings<br />
●<br />
●<br />
Farmers are well aware of the importance of line sowing,<br />
yet they do not follow this practice on their fields,<br />
especially in kharif season. They are dependent on hired<br />
machinery covering more area in less time. It was felt that<br />
the machinery of agricultural operations should be available<br />
at least at the block or panchayat level.<br />
Bluebull is severe problem for pulses cultivation in the<br />
region, which is also responsible for preference to cereal<br />
crops.<br />
Research initiatives since inception of the centre<br />
The focus of research since the beginning was on identification<br />
of suitable crops and their varieties and development of<br />
improved agronomic practices for increasing crop yield. The<br />
centre involved in development of suitable cropping systems<br />
and alternate land use systems. The centre developed feasible<br />
and economically viable, soil, crop & water management<br />
techniques for south western zone of Uttar Pradesh. The major<br />
emphasis was on rain water management, integrated nutrient<br />
management, energy management, crops and cropping systems,<br />
contingency planning, tillage and farm machinery, drought<br />
mitigation strategies and alternate land use system. The centre<br />
has developed many dryland technologies for the region which<br />
led to increased and sustainable production of rainfed crops. The<br />
contingency plan under aberrant weather conditions has been<br />
developed.<br />
Significant achievements<br />
Rainwater management<br />
Rainwater harvesting in farm pond and their availability<br />
indicated that there is good scope of rain water harvesting.<br />
About 1200 m 3 can be harvested each year, which can be utilized<br />
to avoid moisture stress during kharif season or as pre-sowing<br />
irrigation in rabi season. Off season tillage by MB plough /disc<br />
plough helped in increasing moisture conservation (15-20%),<br />
efficient weed control (25-30%) timely land preparation and<br />
sowing resulted in up to 20-30% increase in yield. In various<br />
moisture conservation techniques, planting of pearl millet on<br />
shoulder of ridge in ridge and furrow system of sowing with<br />
40-45 cm row spacing found to be effective technique towards<br />
building in-situ moisture resource, safe disposal of extra rain<br />
water, enhanced biomass, economic yield and reduction in cost<br />
of operation. Under delayed monsoon or late sowing up to 10 th<br />
August, pearl millet sowing by ridge & furrow system gave<br />
appreciable yield without any reduction as compared to yield<br />
recorded in timely sown crop. Kharif crops grown on ridge by<br />
raised bed planter gave higher yield from 13.1 to 27.2 per cent<br />
over yield recorded in respective crops grown on conventional<br />
system. Overall 17.8% more yield harvested with sowing on<br />
95<br />
ridge. Maximum pearl millet yield (PEY) (4992 kg/ha) and<br />
B:C ratio (2.78) were recorded in cluster bean grown on ridge.<br />
The next best PEY and B:C ratio were obtained with sesame.<br />
In delayed monsoon or late sowing up to 1 st week of August,<br />
kharif crops grown on ridge gave appreciable higher mean yield<br />
from 25.7% in pearl millet to 28.8% with cluster bean over yield<br />
obtained in flat system. The highest PEY of 4151 kg/ha was<br />
obtained in cluster bean, followed by sesame. However, sesame<br />
grown on ridge under delayed conditions produced appreciably<br />
higher mean BC ratio of 2.80 followed by cluster bean (2.51).<br />
In tillage and nutrient management system, conventional tillage<br />
comprising of one harrowing in summer + one harrowing after<br />
onset of monsoon rains and two ploughings by cultivator and<br />
one intercultural operation were found to be effective and<br />
productive tillage practice. The grain yield of pearl millet<br />
increased significantly with respect to different tillage practices.<br />
The maximum yield (2720 kg/ha) was obtained with summer<br />
tillage by MB plough/disc plough, which was 22.8% more over<br />
yield obtained in tillage by cultivator alone. To evolve a suitable<br />
device for sowing of kharif crops, ridger seeder appeared to be<br />
more effective seeding device in rainfed areas, gave maximum<br />
mean yield (2752 kg/ha.) and BC ratio (2.42).<br />
Cropping systems<br />
The pearl millet grown on ridge in ridge and furrow system was<br />
found more effective and gave overall 25.5% more yield over<br />
flat system of sowing. Among different varieties of mustard,<br />
Bio-902 followed by NRCHB-101 & DRMRIJ-31 (GIRIRAJ)<br />
are identified as higher yielders. In various cluster bean based<br />
inter cropping system tested, cluster bean + pearl millet/sesame<br />
grown in 6:1 row ratio produced higher CBEY. In sub-normal<br />
monsoon year cluster bean + pearl millet/sesame was more<br />
beneficial system. Experience from the field study indicated<br />
that soil surface temperature always is higher by 12-15°C over<br />
atmospheric temperature during late September or early October,<br />
leading to low mustard yields, therefore sowing in 2 nd week of<br />
October (11-20 Oct) was found to more appropriate sowing<br />
time of mustard. Among high value crops (vegetables), bottle<br />
gourd performed better when grown on ridge and proved to be<br />
more profitable. Aonla/Ber based agri-horti system was found<br />
profitable and drought proof. For better resources utilization and<br />
highest net return, inter space between ber plants, green gram,<br />
sesame should be grown. Inter spaces in Aonla orchard, can be<br />
utilized for growing kharif pulses and oilseed, i.e., sesame.<br />
Crops grown on ridge recorded appreciably higher mean yield<br />
of 13.1 to 27.3% in normal sowing conditions and 20.8 to 27.7%<br />
more in delayed sowing conditions (up to 30 th July) over to yield<br />
obtained under flat system of sowing under both conditions<br />
respectively. The mean of PEY of 13.1 to 27.0% higher<br />
recorded with ridge planting over to flat system of sowing and<br />
highest PEY recorded with cluster bean. In delayed conditions
higher PEY (4151 kg/ha) was recorded with cluster bean. The<br />
maximum mean B:C ratio of 2.78 with cluster bean in normal<br />
and 2.80 with sesame under ridge plant of both crops in delayed<br />
sowing conditions respectively. Over all 17.8 and 25.6% more<br />
PEY registered with ridge sowing in normal and delayed sowing<br />
conditions.<br />
Integrated nutrient management<br />
Application of N (75 kg/ha) equally split in three parts (1/3 at<br />
sowing +1/3 at tillering and 1/3 at flag leaf stage, found to be<br />
more advantageous for boosting yield of pearl millet, produced<br />
<strong>37</strong>.8 and 17.3 per cent more yield over full N applied at sowing<br />
and split in two parts. Impact of potassium application on mustard<br />
reveals that recommended dose of fertilizer (60 + 40 kg N/ha)<br />
in conjunction with 50 kg K/ha as basal produced significantly<br />
higher mean yield (2507 kg/ha) which was 73.0 and 17.5 per<br />
cent superior over yield obtained without K (1449 kg/ha) and<br />
25 kg K/ha (2133 kg/ha) addition. Benefit cost (B:C) ratio of<br />
5.08 also higher registered in same practices. Application of 40<br />
kg sulphur by gypsum in association with RDF (20 + 40 kg NP/<br />
ha) proved to effective for achieving economically higher yield<br />
of cluster bean . For realizing more benefit application of crop<br />
residue @ 5.0 tons/ha as mulch for moisture conservation and<br />
RDF (40 + 20 kg NP/ha) along with sulphur @ 20 kg /ha prove<br />
to be ideal practice. Site specific nutrient management on pearl<br />
millet under rain fed areas revealed that application of 25% more<br />
RDF (75+50+50 kg NPK/ha) along with all limiting nutrient<br />
(Zn, B and Mn) on soil test basis gave mean highest yield (3523<br />
kg/ha). However, 25% more RDF with zinc @ 25 kg/ha proved<br />
to be more effective, produced economically higher yield (3166<br />
kg/ha) and BC ratio (3.57). Efficient management of deficient<br />
nutrient indicate that application of Zinc, Boron and sulphur<br />
(on soil test basis) in association with RDF (on soil test basis)<br />
in mustard realized maximum mean yield of (1644 kg/ha) by<br />
applying 25% more RDF and all limiting nutrients. However,<br />
25% more RDF in association with sulphur @ 25 kg/ha gave<br />
economically higher yield (1616 kg/ha) and BC ratio (3.29).<br />
Application of FYM to be equivalent of 50% nitrogen of RDF<br />
(30 kg N/ha) in conjunction with rest 50% N of RDF to meet<br />
through inorganic fertilizer proved to be effective combinations<br />
of fertilizer schedule, could sustained productivity of pearl<br />
millet.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
The centre is working in close collaboration and consultation<br />
with ICAR-CRIDA, AICRP on Use of saline water in<br />
agriculture, cropping system, IISWC centre, Chhalesar, State<br />
Line department, KVKs, and NGOs along with farmers of the<br />
district for developing and refining technology for improving<br />
profitability in rainfed farming and passing on the technologies<br />
to development agencies and extension functionaries for faster<br />
adoption by the farmers. Centre has also developed linkage with<br />
CAZRI, Jodhpur and Coordinating cell of AICRP on sesame &<br />
niger, JNKVV, Jabalpur. Centre also takes technical inputs from<br />
IISWC, Chhalesar and National Research Centre on Rapeseedmustard,<br />
Bharatpur to generate valuable output for the benefit of<br />
the rainfed farmers.<br />
Impact of technologies<br />
Ridge planting of pearl millet resulted in higher productivity.<br />
Pearl millet performed better on ridges with a grain yield of<br />
2288 kg/ha compared to farmers practice (1586 kg/ha). The<br />
increase in the yield is 44.3% and net return is Rs. 1<strong>37</strong>61/- with<br />
a BC ratio of 2.23 over farmers’ practice of broadcasting of<br />
seed. Ridge planting provides enough aeration and porosity to<br />
soil for enhanced root growth apart from safe disposal of excess<br />
rainwater and reduction in soil loss. Pearl millet is grown on<br />
1.07 lakh ha in the region with an average of 1407 kg/ha. There<br />
is a scope to enhance yield level up to 2288 kg/ha. Deep tillage<br />
in summer and compartmental bunds after germination can<br />
support up to 1.5 to 2.0 tones/ha of pearl millet yield under rain<br />
fed conditions. Deep tillage + compartmental bunds conserve<br />
moisture effectively and gave a pearl millet (WCC-75) yield of<br />
S.P. Singh et al.<br />
1875 kg/ha which is 31% higher than yield attained with farmers<br />
practice (1230 kg/ha). This technology gave a net return of Rs.<br />
10,045/ha with B:C ratio of 3.23 as compared to farmers practice,<br />
even during sub-normal rainfall situations. Supplemental<br />
irrigation at flowering and silique formation stages of mustard<br />
give a yield of 2076 kg/ha compared to1459 kg/ha under farmers<br />
practice. The yield advantage is about 42.3% with a net income<br />
of Rs. 10,000/ha and B:C ratio of 3.80. Mustard is grown in<br />
about 79,000 ha in Agra district.<br />
With the adoption of supplemental irrigation to rainfed mustard,<br />
additional production valued at 79 crores could be realized by<br />
the farmers in the district. Sesbania green manuring resulted<br />
in higher mustard productivity in semi-arid Inceptisols of<br />
Agra region of Uttar Pradesh. The improved technology<br />
involves raising a green manure crop during kharif season and<br />
incorporation into the soil, The field is prepared in advance<br />
before onset of monsoon. Seeds of Sesbania aculeata are<br />
broadcast in dry soil. Planking and bund making is done across<br />
the slope to check runoff from the field, Sesbania crop is<br />
ploughed back into soil after 40-45 days after sowing. Mustard<br />
(Varuna, Rohini) is sown during rabi with a nutrient application<br />
of 45 kg N + 40 kg P 2<br />
O 5<br />
/ha. In Agra district, mustard is grown<br />
on about 79,000 ha in fallow-mustard sequence. If Sesbania is<br />
included in this system, considerable saving of N fertilizer can<br />
be made. At present about 15-20% area is under the improved<br />
technology. Application of K along with recommended dose of<br />
N and P gave mustard yield of 2039 kg/ha compared to farmers<br />
practices (1603 kg/ha) which was higher by 27.2 percent. The<br />
net income of Rs 56736/ha with BC ratio of 5.09 was registered<br />
with improved practice as compared to farmers practice which<br />
gave net income of Rs 42305/ha and BC ratio of 4.07. Further,<br />
it was observed that additional investment on MOP fertilizer to<br />
mustard gave ten times more return. Mustard is grown on 1.15<br />
lakh ha in the region with an average yield of 1700 kg/ha. There<br />
is scope to enhance yield level up to 2100 kg/ha. Strip cropping<br />
of pearl millet + cluster bean (4:4) gave pearl millet equivalent<br />
yield of 2587 kg/ha (1040 kg pearl millet + 555 kg cluster bean)<br />
with an advantage of 29.4% yield over farmers practices (2000<br />
kg/ha) and additional yield of 600 kg/ha with extra net income<br />
of Rs. 4000/ha, with BC ratio of 2.54.<br />

Brief history of the Centre<br />
Hisar centre of All India Coordinated Research Project on<br />
Dryland Agriculture started in June, 1971 . Subsequently, an<br />
Operational Research Project was started at under AICRPDA<br />
in 1984 for on-farm research i.e. testing, refining and transfer<br />
of technologies. The project undertook experiments to<br />
generate location specific technologies focusing on rainwater<br />
management, cropping systems, nutrient management, energy<br />
management, evaluation of improved varieties and alternate<br />
land use systems.<br />
Agro-climatic zone characteristics<br />
All India Co-ordinated Research Project for Dryland Agriculture,<br />
Hisar centre is located at Chaudhary Charan Singh Haryana<br />
Agricultural University, Hisar, Haryana. The climate in the zone<br />
is sub-tropical and monsoonal type with prolonged hot period<br />
from March-October and fairly cool winters. The normal onset<br />
of monsoon in the zone is during first week of July and normal<br />
withdrawal is during third week of September. Average annual<br />
rainfall in the zone is about 425.5 mm (kharif with 3<strong>37</strong>.8 and<br />
rabi with 54.9). Major portion (75-80%) of the annual rainfall is<br />
received in June-September. The mean maximum and minimum<br />
temperatures in the zone are 48 °C and 1-2 °C, respectively.<br />
Intermittent dust storms are also common in the region. The dry<br />
spells had been experienced during kharif season coinciding with<br />
seedling, vegetative and reproductive stages of the major rainfed<br />
crops. In the post monsoon winter season, few light showers<br />
(15-20% of annual) are received from westerly depressions.<br />

Dryland agriculture problems<br />
●<br />
●<br />
●<br />
Light soil texture: Soils in dryland areas are light textured<br />
with undulating topography and have poor water retention<br />
capacity.<br />
Poor soil fertility: Soils in these areas are light textured,<br />
poor in organic C and consequently poor in all major and<br />
micro-nutrients.<br />
Poor socio-economic conditions of the farmers and low<br />
adoption of developed technologies.<br />

The maximum net returns of Rs. 12890 ha -1 with BC ratio<br />
of 1.81 from a yield of 1030 kg ha -1 were attained when<br />
greengram was sown across the slope in kharif.<br />
Deep ploughing before the onset of monsoon was superior<br />
and gave a maximum and significantly higher mustard yield<br />
of 2556 kg ha -1 , net income of Rs.29594 ha -1<br />
The highest grain yield of pearl millet was obtained with<br />
pond silt @ 60 t ha -1 (1276 kg); and N 60 + P 2<br />
O 5<br />
30 kg ha -<br />

(1402 kg), respectively. The maximum seed yield (1945 kg<br />
ha -1 ) of mustard was obtained with pond silt @ 60 t ha -1 and<br />
N 60 + P 2<br />
O 5<br />
30 kg ha -1 .<br />
Maximum grain yield of pearl millet and mustard were<br />
recorded in RDF + two sprays of Thiourea (2701 kg ha -1 )<br />
and (2548 kg ha -1 ) followed by RDF + 1% KNO3 (2500 kg<br />
ha -1 ) and (2489 kg ha -1 ), resulting in higher net return and<br />
B:C ratio. These treatments were significantly higher than<br />
RDF + No spray and RDF + Water spray 2.<br />
Supplemental irrigation (25 mm) from harvested rain water<br />
in farm pond to pearlmillet gave higher pearlmillet equivalent<br />
yield (2177 kg ha -1 ), net returns (17704 ha -1 ), B:C ratio<br />

●<br />
(1.95) and RWUE (10.78 kg ha -1 mm -1 ) compared to without<br />
supplemental irrigation (1976 kg ha -1 ). Similarly, greengram<br />
recorded significantly higher pearl millet equivalent yield<br />
(2133 kg ha -1 ), than pearl millet (2020 kg ha -1 ).<br />
In intra-plot rainwater harvesting, maximum pearl millet<br />
equivalent yield of 2860 kg ha -1 was observed with green<br />
gram under 75% slope and 2/3 rd donor area and the lowest<br />
pearl millet equivalent yield of 1526 kg ha -1 was obtained<br />
by pearl millet under 1.5% slope ½ donor area.<br />

Castor paired rows (60-120-60 cm) + two rows of greengram<br />
was superior with maximum castor equivalent yield of 1030<br />
kg ha -1 , net income of Rs. 7057 ha -1 and B:C ratio of 1.45.<br />
Mothbean in paired rows (30-60 cm) + one row of clusterbean<br />
was superior with significantly higher mothbean equivalent<br />
yield of 1154 kg ha -1 , net income of Rs.11891 ha -1 and B:C<br />
ratio of 1.81.<br />
Chickpea as sole crop at 30 cm spacing gave significantly<br />
higher chickpea grain equivalent yield (1948 kg ha -1 ). Inter/<br />
strip cropping of chickpea + barley in 2:1, 4:2 and 6:3 ratios<br />
did not significantly increase chickpea equivalent yield<br />
over sole chickpea. Highest B:C ratio was attained under<br />
chickpea + barley (6:3).<br />
Pearlmillet + mungbean ( 8:4 row ration) was superior with<br />
maximum pearlmillet equivalent yield of 2756 kg ha -1 , net<br />
income of Rs. 9641 ha -1 and BC ratio of 1.67.<br />
Grain yield of Sesbania was recorded highest (1054 kg<br />
ha -1 ) in Sesbania sole at 60 cm. Grain yield of pearl millet<br />
was recorded highest (1778 kg ha -1 ) in pearl millet sole at<br />
45 cm spacing. Sesbania + pearl millet intercropping gave<br />
negative net return due to excessive vegetative growth of<br />
Sesbania at initial stage of crop.<br />

Energy management<br />
●<br />
●<br />
Improved ridger seeder places seeds and fertilizer in single<br />
operation and sowing seeds of pearl millet at appropriate<br />
depth (3-4 cm) in the moist zone on the shoulders of the<br />
ridges for overcoming problem of seed burying with extra<br />
soil cover. This results in better germination. It can be<br />
used for rabi crops with better results. It makes furrows<br />
by removing the dry soil and places the seeds in furrows<br />
with adequate moisture. It forms ridges of 30 cm wide and<br />
15 cm height. Depth of sowing can be adjusted. Improved<br />
technology gave yield of 2640 ha -1 , net returns of Rs.80127<br />
ha -1 , B:C ratio of 3.90 and RWUE of 61.51 kg ha -1 mm -1<br />
when compared to farmers practice (2284 ha -1 ).<br />
Harrowing with tractor drawn disc harrow in kharif is more<br />
effective for in-situ moisture conservation, which results<br />
in raising better chickpea crop in rabi. Harrowing is done<br />
after each effective rainfall event of >15 mm. Disc harrow<br />
pulverizes soil to deeper layers for better infiltration of<br />
rainwater into the soil profile. Sowing of chickpea (C-235)<br />
is done in second fortnight of October with bullock or camel<br />
drawn country plough. The cost of this harrow is Rs.25000<br />
and cost of harrowing is Rs.500 ha -1 . A significantly higher<br />
chickpea seed yield of 965 kg ha -1 was realized when disc<br />
harrowing is done during kharif, which is 44 % higher than<br />
farmers practice.<br />
Contingency crop planning<br />
For kharif planning<br />
a. Suggested contingency crops/ cropping systems and<br />
cultivars under delayed onset of monsoon<br />
Delay by 2 weeks (3 rd week of July)<br />
●<br />
Pearl millet hybrids (HHB-67 (Improved), HHB 197, HHB<br />
272, HHB 226); clusterbean (HG 563, HG 365, HG 2-20);<br />
greengram (MH 421, MH 318)<br />
● Intercropping systems: Pearl millet (HHB-67(Improved) +<br />
greengram (MH 421) (8:4)<br />
Delay by 4 weeks (1 st week of August)<br />
● Pearl millet (HHB-67 (Improved), HHB 197, HHB 272,<br />
HHB 226) can be sown latest by first week of August<br />
● Pearl millet (HHB-67 Improved); clusterbean (HG 365);<br />
greengram (MH-421)<br />
●<br />
Thinning to reduce 1/3 rd population should be done in<br />
timely sown crop<br />
●<br />
Sowing of clusterbean (HG 563, HG 365, HG 2-20) may be<br />
ensured by end of July and pulses by first week of August<br />
with early maturity varieties<br />
Delay by 6 weeks (3 rd week of August)<br />
●<br />
●<br />
●<br />
Transplant pearl millet hybrid HHB-67 (improved)<br />
Avoid sowing of clusterbean and conserve the moisture for<br />
rabi sowing. However, some area may be used for fodder<br />
(cowpea/greengram)<br />
Do not prefer sowing of sesame beyond mid-August.<br />
Delay by 8 weeks (3 rd week of August)<br />
●<br />
●<br />
Keep land fallow<br />
Conserve moisture for rabi crops<br />
b. Crop, soil, water and nutrient management strategies<br />
during seasonal drought<br />
Early season drought<br />
●<br />
●<br />
●<br />
●<br />
●<br />
In pearl millet, if the plant stand is less than 60 %, go for<br />
resowing as and when rains resume and gap filling by<br />
transplanting under rainy conditions<br />
After receiving 25-50 mm of rainfall, 2 to 3 ploughings to<br />
be done using cultivator followed by sowing<br />
One interculture operation for removing weeds and better<br />
moisture conservation<br />
Avoid fertilizer application, if effective rainfall received<br />
at a later period. Apply second half (20 kg N ha -1 ) as top<br />
dressing at knee high stage (25-30 DAS) in pearl millet.<br />
Practice of intercropping (strip cropping of greengram in<br />
8:4 at 30 cm row spacing with pearl millet as main crop.<br />
Mid-season drought<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Open conservation furrows and ridge and furrow for<br />
rainwater harvesting<br />
Straw mulching in between rows<br />
Frequent interculture; weeding and hoeing with wheel hand<br />
hoe/kasola<br />
In pearl millet, harvest every third row for green fodder<br />
and make ridge and furrow for in-situ rainwater harvesting;<br />
weeding and hoeing with wheel hand hoe/kasola as and<br />
when required<br />
Provide life-saving irrigation (4-5 cm), if possible<br />
● Foliar spray of water-soluble complex fertilizer (18:18:18)<br />
@ 0.5% + 0.5% ZnSO 4<br />
in pearl millet during dry spell<br />
●<br />
Avoid chemical weed control<br />
Terminal drought<br />
●<br />
●<br />
Remove every third row of pearl millet for green fodder.<br />
Provide life-saving irrigation, if available.<br />
101
● Harvesting of intercrop at physiological maturity<br />
(greengram)<br />
●<br />
●<br />
Field preparation for rabi crop sowing during first fortnight<br />
of October<br />
Sowing of mustard (RH 30, RB 50, RH 725, RH 119, RH<br />
406, RH 761) and chickpea (HC 1) during second fortnight<br />
of October.<br />
For rabi planning<br />
a. Suggested crops and varieties for delayed season<br />
●<br />
Mustard (RH 30, RB 50, RH 406, RH 725, RH 761) and<br />
chickpea (HC 1).<br />
● Foliar spray of water-soluble complex fertilizer (18:18:18)<br />
@ 0.5% + 0.5% ZnSO 4<br />
in mustard during dry spell.<br />
Agro-hortisystems<br />
●<br />
Jandi (Local) + greengram (MH 421) ; spacing for jandi<br />
(6*6 m) and greengram (45 x 10 cm)<br />
● Ber (Gola, Seb, Illachi, Kaithli) + greengram (MH 421);<br />
spacing for ber (10 x 10 m) and greengram (45 x 10 cm).<br />
Impact of technologies<br />
Pearl millet (cv. HHB-67) hybrid gives 20 per cent higher grain<br />
yield (2975 kg ha -1 ) with B:C ratio of 1.68 as compared to<br />
existing hybrids i.e. HHB 50 (2475 kg ha -1 ) and HHB 60 (2719<br />
kg ha -1 ). Even under low rainfall and light textured soils, HHB-<br />
67 gives a yield of 1284 kg ha -1 , which is 20% more than HHB-<br />
50 (1090 kg ha -1 ). Strip cropping of pearl millet + greengram<br />
Thakral et al.<br />
(8:4) for higher productivity in Western Dry Zone of Haryana.<br />
Strip cropping of pearl millet + greengram (8: 4) gives a pearl<br />
millet equivalent yield of 3196 kg ha -1 , net income of Rs. 2<strong>37</strong>32<br />
ha -1 and B:C ratio of 2.26. This practice ensures some yield<br />
advantage during drought years. In case of early drought, pearl<br />
millet can survive but legumes cannot whereas, while under<br />
terminal drought situation, the performance of pearl millet is<br />
risky. Thus, this technology provides an opportunity of realizing<br />
good yields and income to the farmers from either of the crops<br />
in case of weather aberration.<br />
Nutrient management for higher productivity of pearl millet in<br />
South-western Dry Zone of Haryana. The improved practice<br />
gives a grain yield of 1843 kg ha -1 compared to 716 kg ha -1 under<br />
farmers’ practice. An additional income of Rs.535 ha -1 with B:C<br />
ratio of 3:1 can be achieved through nutrient management. This<br />
improved practice has been adopted on 189000 ha, i.e, 30%<br />
of pearl millet area in Haryana. Harrowing with tractor drawn<br />
disc harrow is practiced in 45000 ha in south-western district of<br />
Haryana. A significantly higher chickpea seed yield of 965 kg<br />
ha -1 is realized when disc harrowing is done during kharif, which<br />
is 44% higher than farmers practice. An additional net return of<br />
Rs. 4000 ha -1 with a B:C ratio of 1.42 can be realized with disc<br />
harrowing. Improved ridger seeder for planting rainfed crops in<br />
Southern Dry Zone of Haryana. Sowing with ridger seeder saves<br />
15% seed, 60% on labour and operating time and 45% in cost of<br />
sowing. Pearl millet grain yield can increase up to 23%, giving<br />
an additional net returns of Rs.1400 ha -1 with a B:C ratio up to<br />
2.34.<br />

Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture (AICRPDA) Centre came into existence as a<br />
sub-centre at Anand in 1970-71 and it was then shifted to<br />
Sardarkrushinagar in 1979. The Centre was elevated to main<br />
centre in 1984.<br />
Agro-climatic zone characteristics<br />
It is located in the North Gujarat Agro-climatic Zone- IV. The<br />
domain districts of the AICRPDA centre, Sardar Krishinagar are<br />
located in Northern Gujarat Zone (NARP) in Gujarat and in the<br />
Agroecological subregion (ICAR) 2.3 and in the agroclimatic<br />
region-13 (Gujarat plains and hills as per Planning Commission).<br />
The represents North Gujarat zone with seven domain districts<br />
under its jurisdiction viz., Banaskantha, Aravali, Sabarkantha,<br />
Patan, Mehsana, Gandhinagar and Kachchh. The climate of the<br />
zone is arid to semi-arid. The mean annual rainfall of the zone<br />
is 749.5 mm and receive in 26 rainy days. About 75% of the<br />
rainfall is received during last week of June to end of September.<br />
The normal onset of the monsoon is during 26 th to 27 th SMW<br />
and withdrawal is during 38 th SMW. In general, winter is very<br />
cold and dry whereas, summer is extremely hot. May is the<br />
hottest month while January is the coolest, the monsoon season<br />
varies from June to September present the rainy months. The<br />
mean monthly maximum temperature ranges between 26 °C and<br />
42 °C. The mean monthly relative humidity varies from 60 to<br />
80%. The PET varies from 1614 to 1998 mm.<br />

Dryland agriculture problems<br />
The problems related to domain districts are:<br />
Soil and land management<br />
●<br />
●<br />
●<br />
Loamy sand soils with shallow depth and low moisture<br />
retention capacity. The maximum water holding capacity<br />
of these soils varies between 22 and 24%. Loamy sand soils<br />
are normally poor in N and P and very low in organic matter.<br />
Some locations are also deficient in S and micronutrients<br />
like Fe and Zn.<br />
The soils have low CEC which results in low retention of<br />
exchangeable nutrients. These soils are highly erodible.<br />
Crusting on drying is a serious problem in seedling<br />
emergence and establishment of a good crop stand.<br />
Crop production<br />
●<br />
●<br />
●<br />
Due to weather aberrations, the crops suffer due to long<br />
dryspells<br />
Lack of suitable implements for farm operations<br />
Unavailability of drought tolerant/ short duration varieties<br />
Socio-economic<br />
●<br />
●<br />
●<br />
●<br />
Small land holdings and pose problems in implementing<br />
land development programmes<br />
Investment capacity and risk bearing status is of dryland<br />
farmers is less.<br />
Market risks<br />
Inadequate availability of agriculture inputs during the<br />
season and for contingent measures<br />
Significant achievements<br />
Rainwater management<br />
●●<br />
In situ moisture conservation with compartmental bunding<br />
of 3.0 m x 4.5 m in pearlmillet grown in moderate slopy soil<br />
for resulted in higher yield while in compartmental bunding<br />
of 3.6 m x 6.0 m in castor gave higher castor yield.<br />
103
●<br />
Adopting castor and cotton crop rotation system on medium<br />
black soils under rainfed condition, and deep ploughing<br />
with disc plough before sowing resulted in maximum yield<br />
and monetary returns of cotton and castor<br />
● Use of roto till drill for sowing of clusterbean (GG 2)<br />
under rainfed condition gave higher seed yield, monetary<br />
returns and rainwater use efficiency with better moisture<br />
conservation.<br />
●<br />
Opening furrows at 3.6 m interval with application of castor<br />
shell mulch @ 10 t ha -1 after last interculture gave higher<br />
seed cotton yield<br />
Cropping systems<br />
●<br />
●<br />
●<br />
●<br />
Intercropping of pearl millet + cluster bean in 2:2 or 2:1 row<br />
ratio and greengram in 1:3 row ratio gave 10.5 & 25.5%<br />
higher pearl millet equivalent yield, respectively over sole<br />
pearl millet.<br />
Pearlmillet + sunhemp (4:2) at 30 cm spacing (in situ green<br />
manuring of sun hemp around 30 DAS by the help of rotary<br />
weeder) resulted in 19.5% higher yield. Intercropping of<br />
castor + cowpea (1:1) gave 31.5% higher net returns over<br />
normal sowing of castor.<br />
Intercropping of castor (90 x 60 cm) + sesamum (1:1) gave<br />
higher yield and 31.6% higher net return over sole castor.<br />
In pearl millet-clusterbean crop rotation, cultivation of<br />
field with 50% of conventional tillage (one ploughing by<br />
tractor cultivation) + interculturing at 20 and 40 DAS + preemergence<br />
application of atrazine @ 0.5 kg ha -1 for pearl<br />
millet and pendimethalin @ 1.0 kg ha -1 for cluster bean was<br />
found optimum. In this crop rotation, application of 80 kg<br />
N ha -1 for pearl millet and 20 kg N ha -1 for cluster bean<br />
through urea or 50% N through chemical fertilizer and 50%<br />
N through FYM resulted in higher yield and net returns.<br />
● Castor taken as a relay crop in greengram resulted in 45.6%<br />
higher greengram equivalent yield over greengram alone, in<br />
which greengram was sown at onset of monsoon and castor<br />
sown after first picking of greengram.<br />
●<br />
●<br />
●<br />
In agri-horti system, intercropping of either greengram<br />
or sorghum in ber was found beneficial and gave higher<br />
monetary return of 27.3 and 15.5%, respectively, over sole<br />
ber.<br />
Karingado taken as a mixed crop along with pearl millet<br />
in every third row gave 9.5% more pearl millet equivalent<br />
yield. Similarly, Karingado grown as a mixed crop in<br />
sorghum at every 6 th line gave higher monetary return under<br />
drought condition over sole sorghum.<br />
Spraying of 5% Kaoline solution in pearl millet at 30 DAS<br />
gave 6.4% more yield as well as it mitigate stress condition<br />
under rainfed condition.<br />
Patel et al.<br />

●<br />
●<br />
●<br />
Intercropping of black gram in cotton hybrid (120 x 30 cm)<br />
(1:1) on medium black soil gave higher cotton equivalent<br />
yield and net return over sole cotton.<br />
Intercropping of maize in castor (1:1) at 45 cm spacing<br />
resulted in higher yield and net return over sole cotton.<br />
Sowing of sole moth bean at 45 cm or intercropping of Bt.<br />
cotton + moth bean (1:2) gave higher cotton equivalent<br />
yield as well as monetary returns in medium black soil of<br />
Kutch region under rainfed condition.<br />

Application of half dose of recommended N (HRD-N)<br />
through fertilizer along with HRD-N through Gliricidia<br />
leaves green manuring in between the two row of pearl<br />
millet and clusterbean gave 42.6 and 17.4% higher yield,<br />
respectively over control as well as improved fertility status<br />
of soil.<br />
Castor fertilized with 60-40-40 kg NPK ha -1 was found<br />
optimum and resulted in 23.6% higher yield over control<br />
(NP).<br />
Application of 25% recommended dose of N as basal and<br />
75% RDN at 20 to 25 DAS for rainfed pearl millet and<br />
sorghum was beneficial for increasing yield and monetary<br />
return.<br />
Application of 50% RDN as basal and 50% RDN in<br />
two equal splits at 20 to 25 DAS and 40 to 45 DAS is<br />
recommended for castor.<br />
In pearl millet, clusterbean and castor crop rotation,<br />
integration of half recommended dose of N (HRD-N)<br />
through fertilizer along with HRD-N through FYM<br />
improved the yield of pearl millet, clusterbean and castor<br />
to the extent of 99, 86 and 89%, respectively over control.<br />
Application of three sprays of FeSO 4<br />
@ 0.5% along with<br />
ZnSO 4<br />
@ 0.5% (with 0.05% citric acid and lime solution<br />
@ 0.25%) at 30, 40 and 50 DAS along with recommended<br />
dose of fertilizers (80+40 kg N, P 2<br />
O 5<br />
ha -1 ) on medium black<br />
soil deficient in Fe and Zn under rainfed condition gave<br />
higher grain and fodder yield of maize as well as monetary<br />
return.<br />
In green gram-sesame crop rotation on loamy sand soils<br />
in organic farming, application of recommended dose of<br />
nitrogen @ 20 kg ha -1 for green gram and 50 kg N ha -1<br />
to sesame either through vermicompost or FYM gave the<br />
maximum yield and net returns.<br />
In castor-clusterbean crop rotation under rainfed conditions,<br />
it is recommended to apply Azotobactor (Azo 8) + PSB (5<br />
ml/kg seed) as seed treatment and 40 kg P 2<br />
O 5<br />
ha -1 as basal<br />
to both crops and 30 kg N ha -1 through vermicompost (2.5<br />
t ha -1 ) and 30 kg N ha -1 through chemical fertilizer to castor
crop while 10 kg N ha -1 through vermicompost (0.83 t ha -1 )<br />
and 10 kg N ha -1 through chemical fertilizer to clusterbean<br />
crop for obtaining higher yield and net returns.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
Patel et al.<br />
Dryland technologies were upscaled on farmers’ fields in<br />
collaboration with KVKs, department of agriculture and<br />
department of watershed, Government of Gujarat. District<br />
agriculture contingency plans were upscaled with the<br />
help of ATMA. The farm pond technology and soil and<br />
water conservation measures such as deep ploughing and<br />
compartmental bunding were upscaled through watershed<br />
program. The centre in collaboration with other AICRP schemes<br />
106<br />
such as AICRP on small millet (pearl millet: GHB-558, GHB-<br />
538, GHB 1129), and legume research station developed various<br />
improved varieties of crops viz.,greengram: GM 3, GM 4, GM<br />
6, cowpea: Gujarat Cowpea-1, Gujarat Cowpea-2, Gujarat<br />
Cowpea-4, Gujarat Cowpea-6, clusterbean: GG- 1, GG 2 pigeon<br />
pea: BDN 2. Oilseed research station (castor, GAUCH-1, GCH-<br />
2, GCH-4, GCH-5, GCH-6, GCH-7 and GCH 8), mustard: GM<br />
2, GDM 4& GDM 5 which helped to increase the productivity<br />
of these dryland crops. All these varieties were evaluated and<br />
upscaled through frontline demonstration in farmers’ fields in<br />
the domain area through KVKs of SAUs, ATMA and other<br />
line departments operating in the zone. Alternate land use<br />
management practices, viz, intercropping of clusterbean and<br />
sorghum in Ber and amla, were upscaled through department of<br />
horticulture.<br />
Impact of technologies<br />
Sowing of castor crop with ridges and furrow method of sowing<br />
for maximum use of harvested rain water in the furrows for<br />
in-situ moisture conservation gave yield of 1398 kg ha -1 of castor<br />
crop. Upscaling of this technology in 10% castor area (44970<br />
ha) in North Gujarat region, the expected additional yield of<br />
5666.2 metric tonnes with Rs. 8.32 crores as additional gain<br />
to the farmers of this region. Adoption rate of compartmental<br />
bunding for moisture conservation in North Gujarat is 41746 ha<br />
(8.8%) and productivity of pearl millet is increased 8 to 10%. In<br />
North Gujarat, at present this technology which gives Rs.16.3<br />
crores additional income. With adoption of mulching with castor<br />
shell in castor in North Gujarat the farmers can get 25% more<br />
yield and net return of (Rs. 34939 ha -1 ) than farmers’ practice.<br />
Intercropping of castor (GCH 7) + green gram (Gujarat Mung 4)<br />
(1:1) gave castor equivalent yield of 1671 kg ha -1 and net return<br />
of Rs. 64934 ha -1 with a B:C ratio of 4.96 as compared to sole<br />
castor. Adoption of this technology is between 12 to 15% in<br />
different districts. Adoption of integrated nutrient management<br />
(75% RDN-FYM + 25% RDN-urea + PSB + Azotobacter) in<br />
pearl millet helps in realizing an additional pearl millet yield of<br />
1654 ton and Rs.2.15 crores in 5% rainfed area (5514 ha).<br />
Way forward<br />
The future research has to focus on sstrengthening of IFS in<br />
dryland agriculture, to enhance in-situ moisture conservation<br />
in soil, introduction of medicinal crops in dryland ecosystem,<br />
rainwater management on watershed basis for intensification of<br />
soil and water conservation, alternate land use system including<br />
agri-silvi, agri-horti and horti-pastoral system, and INM with<br />
focus to reduced dependence on external input. Technologies for<br />
sustainable soil health management include enhancing moisture<br />
holding capacity through use of alternate sources of organic<br />
manures and sub soil manuring to improve nutrient availability<br />
from deeper layers, Mechanization which include nano-coated<br />
machinery for energy efficient small scale operation and crop<br />
centric seed to seed mechanization.

Major soil types<br />
The zone has three major soil types and maximum area is covered<br />
by red loamy soil (48% of total geographical area), followed by<br />
red lateritic soil (33.49% of TGA) and red sandy loam (17.61%<br />
of TGA). The eastern taluks of the zone are largely composed of<br />
red sandy soils, while the western taluks have red loamy soils.<br />
The central part the zone has laterite soils and laterite gravelly<br />
soil (1.66% of to a limited extent).<br />
Major rainfed crops<br />
The major rainfed crops cultivated in the zone during kharif are<br />
finger millet, pigeonpea, maize, horsegram, groundnut, field<br />
bean and cowpea.<br />
Dryland agriculture problems<br />
The problems related to domain districts are as enlisted below:<br />
Soil and land management<br />
●<br />
●<br />
●<br />
Red soils have usually shallow depth and low moisture<br />
retention capacity. The water holding capacity of these soils<br />
varies between 10 and 15 cm per metre depth and this is not<br />
sufficient to carry the crops for more than a month after the<br />
cessation of rains. Therefore, only kharif crop is possible.<br />
Crusting on drying is a serious problem in seedling<br />
emergence and establishment of a good crop stand. Red<br />
soils are normally poor in NPK and very low in organic<br />
matter. At places, they are also deficient in Ca, S and B.<br />
The soils have low CEC (10-15 Cmol (p + ) kg -1 which results<br />
in low retention of exchangeable nutrients. These soils are<br />
highly erodible.<br />
Crop production<br />
●<br />
●<br />
●<br />
●<br />
Due to delayed onset of monsoon, long dry spells during<br />
crop growth, early cessation of rains and lower water<br />
holding capacity of the soils, the crops suffer several cycles<br />
of drought.<br />
Heavy infestation of weeds.<br />
Lack of suitable implements for land development, sowing<br />
and inter-cultivation in various crops.<br />
Mono-cropping, lack of crop diversification and integrated<br />
farming system further reduces yield of crops.<br />
Socio-economic<br />
●<br />
The socio-economic survey conducted in several places<br />
highlighted the constraint of timely land preparation and<br />
sowing.
●<br />
●<br />
●<br />
●<br />
The land holdings are very small and pose problems in<br />
implementing land development programmes.<br />
Due to poor economic status of the farmers, investment<br />
capacity and risk bearing status is less.<br />
Lack of support price for dryland crops and marketing<br />
problems and predominant role of middle man.<br />
Inadequate availability of agriculture inputs during<br />
the season and for contingent measures due to weather<br />
aberrations<br />
Research initiatives since inception of the centre<br />
AICRPDA centre, Bengaluru is catering the research needs of<br />
dryland farmers of Southern Karnataka comprising of Zone- IV,<br />
Zone-V and Zone-VI. The main focus is on location specific<br />
problems considering the agro-climatic zones, predominant<br />
rainfed production systems and socio-economic situation with<br />
major emphasis on rain water management, integrated nutrient<br />
management, energy management, crops and cropping systems,<br />
contingency planning, tillage and farm machinery, drought<br />
mitigation strategies and alternate land use system. Research<br />
findings of the centre are being evaluated on farmer’s fields<br />
through Operational Research Project, National Initiative on<br />
Climate Resilient Agriculture and Rainfed integrated farming<br />
system.<br />
The milestones in the research on dryland agriculture in<br />
Karnataka are:<br />
1. Integrated Dryland Agriculture Development (IDLAD)<br />
project in collaboration with State Department of Agriculture<br />
and UAS, Bengaluru started from 1971-1981.<br />
2. Action research-cum extension mode - Operational Research<br />
Project on Dryland Agriculture started during 1976.<br />
3. Watershed development project during 1983-84 with two<br />
model watersheds, one at Mettemari in Kolar district and<br />
other at Bommenahalli in Mysore district started with the<br />
financial assistance from World Bank.<br />
4. All India Co-ordinated Research Project on Agrometeorology<br />
is in operation since from 1984.<br />
5. Six ad hoc projects under soil and water conservation and<br />
fertilizer management themes were in operation from 1990’s<br />
to mid of 2000.<br />
6. The financial support by various organizations in India and<br />
abroad resulted in intensive work on dryland agriculture at<br />
Bengaluru centre. These were;<br />

on nutrient use efficiency, productivity and economics of<br />
finger millet (2021-24)<br />
7. The dryland agriculture technology park comprising various<br />
contingency crop planning measures consisting promising<br />
dryland technologies were demonstrated in a large scale at<br />
AICRPDA since from 2011 for the benefit of farmers and<br />
other dignitaries visiting and nearly 5-6 lakh farmers visit<br />
every year during krishi mela. Long term permanent manurial<br />
trial on finger millet mono cropping and finger milletgroundnut<br />
system is a heritage experiment in operation since<br />
from 1978 for convincing the stakeholders.<br />
8. Custom hiring centre at N<strong>ICRA</strong> village established<br />
during 2011 formed the basis for technical know-how for<br />
establishing Krishi Yantra Dhare programme by Government<br />
of Karnataka.<br />
Significant achievements<br />
Rainwater management<br />
For effective conservation and management of rain water,<br />
graded bunds and levelling of graded border strips in deep red<br />
soils help to reduce the runoff losses and safe disposal of excess<br />
water, thereby increasing the crop yields. Apart from this,<br />
Khus and Nase grass as live bunds conserved soil and water by<br />
reducing the soil loss and runoff by 36% in slope up to 2.5 %.<br />
Vegetative barriers reduced runoff (11-12%) & soil loss (1.52-<br />
1.70 t/ha/year) as compared to control (soil loss: 2.5 t/ha/year)<br />
and helps in increasing the finger millet productivity. Also, insitu<br />
soil moisture conservation through opening of conservation<br />
furrow improved productivity by 25-30 %. Mulching with crop<br />
residue in chilli resulted in enhanced moisture content in soil<br />
which helped in obtaining higher growth and green chilli yield<br />
(30-35%) than crop without mulching. Trench-cum-crescent<br />
bund helped in enhancing productivity and profitability by
impounding water resulting in conservation of higher moisture<br />
content of dryland orchards than that of no trenches. Lining of<br />
farm ponds (brick lining and brick compartment lining) with<br />
400-500 microns gauged LDPE (Low Density Poly Ethylene)<br />
sheet with 8:1 ratio of soil-cement plastering to 5 cm thickness<br />
mortar in brick lining 1m 2 rectangular brick compartments in<br />
brick compartment lining on all the four sides of the farm pond<br />
for higher stability helped in seepage control. The recommended<br />
size of farm pond is 250 m 3 per hectare catchment with 12 m<br />
× 12 m top length and width, 6 m × 6 m bottom length and<br />
width and 3 m depth with 1:1 slope. Subsoiling at 2 m interval +<br />
organic manure resulted in higher productivity and profitability<br />
breaking down the hard subsoil helping in high soil moisture<br />
conservation than the control.<br />
Cropping systems<br />
During early in the season growing of fodder pearl millet<br />
and cowpea followed by green chilli and transplanted finger<br />
millet, respectively was found to be promising double cropping<br />
systems with increased yield and B:C ratio (3.55 and 3.36<br />
respectively) over sole finger millet. During delayed onset of<br />
monsoon, dry seeding of finger millet with higher seed rate<br />
(7.5 kg ha -1 ) in anticipation of rain within 8-10 days was found<br />
to be successful. Practicing cereal based intercropping system<br />
(finger millet + pigeonpea (8:2)/ (10:2), maize + pigeonpea<br />
(1:1) and finger millet + castor (10:1)), pulse based (pigeonpea<br />
+ field bean (1:1), pigeonpea + cowpea (1:1)) and oilseed<br />
based intercropping system (groundnut + pigeonpea (8:2),<br />
groundnut + castor (10:1)) and also bud nipping of castor were<br />
found to be promising by increasing the yield up to 25-30 %<br />
with conservation furrow in paired rows of pigeonpea than sole<br />
cropping. Also, alternate land use system involving finger millet<br />
and mango performed better over their respective sole crops in<br />
terms of growth and yield. Intercropping of amla with finger<br />
millet (1427 kg ha -1 ) was found to be better intercrop among<br />
amla based agri-horti systems, resulting in higher net returns<br />
(₹. 29,446) than sole amla. Similarly, intercropping of custard<br />
apple with fodder maize (2346 kg ha -1 ) was found to be better<br />
in custard apple based agri-horti systems, resulting in higher net<br />
returns (₹.1,19,672) and B:C ratio (6.67) than sole custard apple.<br />
Integrated nutrient management<br />
Integrated nutrient management viz., application of FYM @ 10<br />
t/ha along with 100% NPK resulted in sustained finger millet<br />
productivity and soil health with a mean productivity of 1.8 t/<br />
ha. Similarly, ex-situ glyricidia green leaf manuring to supply<br />
50% N +100% PK improved finger millet yield and also 50%<br />
N through green leaf manure and 50% NPK in finger millet -<br />
soybean-maize rotation system resulted in higher finger millet<br />
(3004 kg/ha), maize (2790 kg/ha) grain yield as compared<br />
to application of recommended NPK (2572 kg/ha, 1150 kg/<br />
ha, respectively). Among secondary nutrients, application of<br />
109<br />
calcium through lime to 45% Ca saturation level (300-400 kg/<br />
ha of agricultural lime) + recommended NPK (25:50:25 kg/ha)<br />
to Alfisols improved the productivity of groundnut (1625 kg/ha)<br />
with a B: C ratio 2.5. Similarly application of sulphur @ 10 kg/<br />
ha in cowpea, blackgram, sunflower and groundnut increased<br />
seed yield (1350, 1160, 1230 and 2000 kg/ha, respectively) as<br />
compared to control. Application of higher dose of potassium<br />
(<strong>37</strong>.5 kg/ha instead of 25 kg/ha) increased the yield in finger<br />
millet (3.5-3.9 t/ha) and application of nitrogen @ 40 kg ha -1 and<br />
potassium @ 20 kg ha -1 resulted in higher grain and straw yield<br />
of little millet (730 & 1282 kg ha -1 respectively) and application<br />
of nitrogen @ 60 kg ha -1 and potassium @ 20 kg ha -1 resulted in<br />
higher grain and straw yield of foxtail millet (856 & 2063 kg ha -<br />
1<br />
) than farmers practice (without potassium application). Also,<br />
application of zinc and boron along with NPK increased seed<br />
yield by 15-21% in finger millet, 8-31% in pulses and 15-<strong>37</strong>%<br />
in oilseeds over farmers practice. Crop rotation with legumes<br />
resulted in higher yield of finger millet. Mixing of finger millet<br />
seeds with complex fertilizers like DAP gave higher grain yield<br />
(2460 kg/ha) and B:C ratio (2.11) as compared to broadcasting<br />
method. Band placement of phosphatic fertilizer below the seed<br />
line resulted in higher grain yield of 5210 kg/ha compared to<br />
broadcasting (4690 kg/ha) in maize.<br />
Crop improvement<br />
Sowing suitable finger millet varieties (Long duration:<br />
MR-1, MR-6, Medium duration: GPU-28, KMR-301 and Short<br />
duration: GPU-28, KMR-316, ML-365) depending upon onset of<br />
monsoon is important contingent crop plan for aberrant weather<br />
and these promising varieties resulted in higher yield and also<br />
reduced the risk of crop failure. Among pulses, improved<br />
varieties in horse gram (PHG-9), pigeonpea (BRG- 1, BRG-2<br />
and BRG-5), field bean (HA-3 and HA-4) and vegetable cowpea<br />
(IT-38956-1, PKB-4 and PKB-6) were promising varieties as<br />
compared to local cultivars. Similarly, among the different<br />
oilseed crops, improved high yielding varieties of groundnut<br />
(JL-24, Chintamani-2, ICGV-91114 and GKVK-5), sunflower,<br />
(KBSH-44 and KBSH-53), sesame (TMV-3), Niger (KBN-1<br />
and KBN-2) and castor (DCS-9) were found to be promising<br />
under dryland condition. Further, Samrudhi a high yielding<br />
chilli variety was found to be promising for green chilli purpose<br />
and recorded 30% higher yield as compared to local varieties.<br />
Energy management<br />
Tractor drawn deep tillage equipment like disc plough, mould<br />
board plough and chisel plough conserves more moisture in the<br />
lower strata of soil and helped in better growth, yield of maize<br />
and pigeonpea and in-situ green manure incorporation through<br />
tractor drawn rotovator (covers one hectare in 90 minutes)<br />
resulted in higher yield (32.6%) with reduction in 50-60%<br />
energy costs. Further, tractor drawn post hole digger helped<br />
in reducing the cost of opening pits by 60-70% depending
upon size of pits. Modified bullock drawn seed drill for finger<br />
millet based intercropping system reduced sowing cost up to<br />
30% (Operational cost is Rs. 400-500/- per hectare). Bullock<br />
drawn multi-furrow opener for groundnut sowing covered an<br />
area of 1.5-2.0 ha/day and cost of operation is Rs. 100-125/ha.<br />
Improved hand tools (improved sickles enhanced efficiency of<br />
operation by 25-30 %) and improved hand weeders require only<br />
5 persons to cover one hectare in a day, whereas 25 persons are<br />
required for doing same work by traditional method. It reduced<br />
weeding cost up to 70% (Cost of operation is Rs. 500-600 per<br />
hectare). Adoption of post-harvest processing equipment like<br />
groundnut decorticator for efficient shelling (98%) reduces cost<br />
by 75% with operation cost of Rs. 250-300/quintal. Improved<br />
tractor drawn seed-cum-fertilizer drill helped in maintaining<br />
optimum plant population and reduced the seed rate up to 70%<br />
compared to farmer's practice (Broadcasting). This seed drill<br />
can also be used in different cropping system viz., intercropping,<br />
strip cropping etc.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
Nine technologies under rain water management, 17 technologies<br />
under cropping systems, 12 technologies under integrated<br />
nutrient management, 9 technologies under participatory<br />
varietal selection/ crop improvement, 12 technologies under<br />
energy management theme were published in package of<br />
practice of UAS-Bengaluru and the same technologies were<br />
implemented and upscaled in farmer’s field in collaboration with<br />
KVK, department of agriculture and department of watershed,<br />
Government of Karnataka.<br />
-<br />
District wise contingency plan and various drought proofing<br />
action plans in the domain agro-climatic zones of the centre<br />
were upscaled with the help of KSDA. The centre, in<br />
collaboration with other AICRP schemes such as AICRP on<br />
small millet, sunflower, pigeonpea and arid legumes developed<br />
various improved varieties of crops viz., Samrudhi chilli, IT-<br />
38956-1 cowpea, PHG-9 horsegram, BRG-5 pigeonpea which<br />
helped to increase the productivity of these dryland crops. All<br />
these varieties were evaluated and upscaled through front line<br />
demonstrations in farmers field, organising field day, etc., in<br />
the domain area through KVK’s of SAU’s, ATMA and other<br />
line departments operating in the zone. Alternate land use<br />
management practices, viz, intercropping in custard apple, amla,<br />
mango and sapota and seed production of new varieties of seeds<br />
was up scaled through department of horticulture under NHM<br />
scheme.<br />
The soil fertility management was upscaled through Bhoo<br />
Chethana program of KSDA & ICRISAT. The SHG’s and FPO's<br />
are operating at village level helped in upscaling of dryland<br />
technologies. The agromet advisory regarding climate change<br />
and a suitable measure that has to be followed was implemented<br />
with the help of AICRP on Agrometerology. The farm pond<br />
technology through Krishi Bhagya scheme, soil and water<br />
conservation measures such as deep ploughing, bunding and<br />
deep trenches in orchards through watershed program helped in<br />
upscaling the dryland technologies.<br />
Impact of technologies<br />
Crop management practices like crop cultivation across the slope<br />
with khus and nase as live barrier at 15 m interval for land slope<br />
of 1-3% reduced and runoff by 36% and soil loss from 1.52 -<br />
1.70 t/ha/year. Similarly opening of trenches up to 30-60 cm<br />
depth and width 50-60 cm using tractor was found to be suitable<br />
for conserving runoff water and this was more suitable for fruit<br />
orchards which helped in getting higher yield. Modified seed<br />
drill helps in maintaining recommended row to row spacing of<br />
30 cm with reduced implement weight by reducing one bowl,<br />
as compared to local implement. It reduces sowing operation<br />
cost up to 30%. The cost of the modified seed drill is Rs.3000/-.<br />
This seed drill has been used by many farmers in few villages of<br />
Kanakapura through Operational Research Project and also in<br />
Nelamangala through National Initiative on Climate Resilient<br />
Agriculture project. Farmers realized that newly modified seed<br />
drill is good and convenient to control weed growth.<br />
By recharging bore well the discharge of bore well was improved<br />
which led to effective utilization of runoff water in dryland and<br />
enhanced the ground water level and yield of defunct bore wells.<br />
The farm ponds lined with 400-500 micron gauge LDPE helped<br />
in minimizing seepage losses and stored water could be used<br />
for two protective irrigations during 20-25 days long dry spell<br />
115
for horticulture crops around the farm pond. This technology<br />
was taken up as one of the flagship programmes under “Krishi<br />
Bhagya” scheme of KSDA which led to popularization of farm<br />
ponds. The farm pond technology (12 m × 12 m top width and<br />
length, 6 m × 6 m bottom width and length, depth of 3 m with<br />
1:1 side slope for one hectare catchment area) is developed by<br />
AICRPDA centre, Bengaluru. This technology is integrated into<br />
Krishi Bhagya scheme of Karnataka and upscaled in Bengaluru<br />
Rural District. About 4 farm ponds are dug out in 4 farmer’s<br />
fields at Bengaluru Rural District. The stored rainwater in farm<br />
pond is being used for supplemental irrigation in rainfed crops<br />
resulting 20-25% in yield advantage/ha and 15-20% income<br />
benefit/ha to the farmers. Similarly, at Kolar 14,424 numbers<br />
of farm ponds are dug in farmer’s field during 2015-2020 by<br />
the KSDA with the technical support of AICRPDA Bengaluru<br />
centre. The stored rainwater in farm pond is being used for<br />
supplemental irrigation in rainfed crops.<br />
Finger millet is grown in an area of 10.2 lakh ha in domain<br />
with mean productivity of 1800 kg/ha during normal rain fall.<br />
By sowing suitable variety depending upon onset of monsoon,<br />
productivity level can be maintained on average of 2100-2200<br />
kg/ha under rainfed condition. Sowing suitable finger millet<br />
varieties depending upon onset of monsoon will increase the<br />
yield and also reduce risk of crop failure. Farmers have the<br />
option of choosing a right variety for right time of sowing.<br />
Improved high yielding varieties of pigeonpea (BRG-1 and<br />
BRG-2), field bean (HA-3 and HA-4) and vegetable cowpea<br />
(PKB-4 and PKB-6) are recommended for rainfed situation<br />
based on their long- term performance. Horse gram is grown in<br />
an area of 0.69 lakh ha in the domain with a mean productivity<br />
of 700-725 kg/ha. Horse gram variety PHG-9 is high yielding,<br />
fairly tolerant to powdery mildew and has bold grain with yield<br />
of 850-950 kg /ha. New variety of cowpea IT38956-1 tolerant to<br />
leaf spot and rust disease suits well for both early and late kharif,<br />
also well suited for double and intercropping system in rainfed<br />
agriculture. Among the different oilseed crops improved high<br />
yielding varieties of groundnut - JL-24, Chintamani-2, ICGV<br />
91114, GKVK-5, sunflower - KBSH-44 and KBSH-53 are<br />
suitable for delayed onset of monsoon as contingent crop, sesame<br />
- TMV-3 (suitable for double cropping), Niger - KBN-1 and<br />
castor - DCS-9 suitable for intercropping in groundnut) helped<br />
in increasing productivity in dryland agriculture. Samrudhi, a<br />
high yielding open pollinated variety of chilli performed well in<br />
dryland situation. Adoption of this variety in 30% of total chilli<br />
area could sustain, green chilli yield.<br />
Growing of finger millet and pigeonpea 10:2 or 8:2 row ratios<br />
using seed drill and maintaining 60 cm spacing between paired<br />
row of pigeonpea helps in conserving water in the furrow and<br />
also the productivity of finger millet can be improved to 2.2-<br />
Mudalagiriyappa et al.<br />
2.5 t/ha during normal rainfall and risk can be reduced during<br />
unfavourable rainfall. This technology is integrated into KSDA<br />
plans/programme in Bengaluru Rural District, Karnataka. This<br />
technology is being adopted on 500 farmer’s field in the district<br />
resulting in 10-15% yield advantage and 15-20% income benefit<br />
to the farmers. Adoption of pulse based intercropping system<br />
involving pigeonpea + field bean (1:1), pigeonpea + cowpea<br />
(1:1), pigeonpea + groundnut (2:4) helped in obtaining 30-40%<br />
higher income than sole crops and also the incorporation of crop<br />
residue enhanced the soil fertility. Intercropping groundnut +<br />
pigeonpea (8:2), groundnut + castor (8:1) is popular. By adopting<br />
this intercropping system, there is good scope for improving the<br />
productivity from 1.4 to 1.6 t/ha during normal rainfall and risk<br />
can be reduced during unfavourable rainfall years. Similarly,<br />
bud nipping in rainfed castor helps in getting higher yield up<br />
to 40%. Intercropping nipped castor with finger millet recorded<br />
higher castor equivalent yield compared to sole castor. If the<br />
improved cropping system is adopted, there is good scope for<br />
improving the productivity to 1.7 t/ha during normal rainfall<br />
years and risk can be reduced during unfavourable rainfall years.<br />
Bimodal distribution of rainfall is favourable for double<br />
cropping thus double cropping of cowpea followed by finger<br />
millet in assured rainfall area helped in sustaining yield and<br />
getting additional income. By following dry sowing of finger<br />
millet, the productivity can be enhanced from 3.74 to 4.03 t/ha<br />
and large area can be sown prior to rain. If this double cropping<br />
of cowpea followed by finger millet in assured rainfall areas of<br />
the state (at least 50 per cent of finger millet area), certainly it is<br />
possible to realize an additional cowpea yield of 2,65,200 tons<br />
or a monetary benefit of Rs. 1.01 crore apart from succeeding<br />
finger millet with improved soil health.<br />
In-situ incorporation of horse gram biomass (18-20 t/ha)<br />
helped in enhancing grain yield upto 2.5 t/ha and saving<br />
50% recommended nitrogen to finger millet. Similarly,<br />
ex-situ glyricidia green leaf manuring to supply 50% N +100<br />
% PK improved finger millet yield and the productivity can be<br />
increased with saving of 50% NPK besides maintaining good<br />
soil health. Applying higher dose of potassium (<strong>37</strong>.5 kg/ha<br />
instead of 25 kg/ha) increased the yield, thus by upscaling of<br />
this improved nutrient management practice, the productivity<br />
can be further improved to 3.5-3.9 t/ha. Application of NPK +<br />
lime to 45% Ca saturation (300-400 kg/ha of agricultural lime)<br />
to Alfisols improved the productivity of groundnut. Application<br />
of sulphur @ 10 kg/ha to cowpea, blackgram, sunflower and<br />
groundnut recorded 25% higher yield. Application of zinc and<br />
boron with NPK increased seed yield of finger millet, pulses<br />
and oilseeds.<br />
Integrated nutrient management, viz., application of FYM<br />
@ 10 t/ha with 100% NPK resulted in sustained finger millet<br />
116
productivity and soil health with a mean productivity of 1.8 t/ha.<br />
Mixing of finger millet seeds with complex fertilizers like DAP<br />
gives higher grain yield as compared to broadcasting method of<br />
fertilizer application. Application of farm yard manure (FYM) @<br />
10 t/ha or maize residue @ 5 t/ha or 2 t/ha of gypsum depending<br />
upon soil pH to finger millet helps in reducing soil crusting with<br />
increased seedling emergence, reduced yield loss to the extent<br />
of 30-40% besides maintaining good soil productivity. Rotation<br />
of finger millet with groundnut integrated with organic manure<br />
resulted in sustained finger millet productivity and soil health as<br />
compared to monocropping of finger millet. Rotation of finger<br />
millet with groundnut resulted in 19-20% increased yield and<br />
soil fertility.<br />
Using deep tillage equipments like disc plough, MB plough and<br />
chisel plough ensures higher yield due to in-situ conservation of<br />
moisture. Sowing finger millet using modified seed drill ensures<br />
recommended row spacing with reduced drudgery of operation.<br />
Improved hand weeder reduce weeding cost up to 70%, and<br />
increase the efficiency by reducing the energy required to<br />
operate. Likewise, improved sickles reduce drudgery to the<br />
extent of 25-30% compared to locally available sickles.<br />
Custom Hiring Centre (CHC) for farm implements/machinery<br />
in Chikkaputtyanaplaya village, Bengaluru Rural District,<br />
Karnataka State is established in the year 2011 by AICRPDA<br />
Centre, Bengaluru under All India Coordinated Research Project<br />
for Dryland Agriculture (AICRPDA) - National Innovations in<br />
Climate Resilient Agriculture (N<strong>ICRA</strong>). This CHC is enabling<br />
the farmers to hire farm implements/machinery at an affordable<br />
cost for various agricultural operations in various crops with<br />
high energy use efficiency. This has enabled timely operations<br />
and promoted small farm mechanization.<br />
Way forward<br />
The Karnataka state has 7.0 m ha of net rainfed area out of 10.3<br />
m ha of net sown area accounting for nearly 70 per cent of the<br />
total cultivated area. About 67 per cent of the total cultivated<br />
area receives an average rainfall of less than 750 mm with<br />
intermittent dry spells. The rainfed areas suffer from constraints<br />
with respect to soil and crop management and socio-economic<br />
issues. Reduction in human resource due to exodus of rural<br />
youth to nearby towns has added another dimension to dryland<br />
problems.<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture (AICRPDA) has carried out location specific<br />
adaptive research in a network mode which resulted in<br />
development of improved dryland technologies in the areas of<br />
rainfed cropping systems, drought management, soil and water<br />
conservation, nutrient management and farm mechanization.<br />
Some of these technologies have already formed part of package<br />
of practices for crops in different states. However, in view of<br />
the increasing importance of rainfed agriculture and the need<br />
for boosting productivity, emphasis is required on climate<br />
smart natural resource management such as development of<br />
best management practices (BMP), water conservation and soil<br />
aquifer treatment (SAT) for sustainable agriculture, application<br />
of communication & information technology and developing<br />
and implementing IT solutions in rain water management, nanotechnology<br />
for soil and water conservation, evaluation of soil<br />
moisture retainers bio-irrigation technique as a drought proofing<br />
strategy, expansion of alternate land use practices as a long<br />
term strategy, promoting commercial dryland agriculture with<br />
protective cultivation under harvested rain water, harnessing<br />
solar energy in non-crop space including harvested water<br />
bodies to fulfil the farm energy demand, e-dryland portal with<br />
emphasis on large scale dissemination of weather forecast, agroadvisory<br />
and interactive modules. Technologies for sustainable<br />
soil health management includes enhancing moisture holding<br />
capacity through use of alternate sources of organic manures,<br />
sub soil manuring to improve nutrient availability from deeper<br />
layers, studies on carbon emission and carbon sequestration<br />
under different land use systems, conservation agriculture, and<br />
geospatial technologies for soil resource management. In crop<br />
improvement, screening of genotypes for multiple resistances<br />
in different dryland crops with major emphasis on drought<br />
tolerance, short duration for climate extremities is essential.<br />
Mechanization and secondary agriculture plays important role<br />
which includes nano coated machinery for energy efficient small<br />
scale operation, crop centric seed to seed mechanization facilities<br />
for small holder farm, and secondary agriculture including postharvest<br />
management. The above listed are some of the issues to<br />
cater to the need of the hour to increase the productivity.<br />

Brief history of the Centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Centre was started in 1972 under Junagadh<br />
Agriculture University. This Centre has been catering to the<br />
needs of the North Saurashtra Agro-climatic Zone for the seven<br />
domain districts viz. Rajkot, Morbi, Jamnagar, Devbhumi<br />
Dwarka, Surendranagar, Bhavnagar and Amreli.<br />
Agro-climatic zone characteristics<br />
The climate in this zone is semi-arid. Out of the total annual<br />
average rainfall of 680 mm, the south- west monsoon contributes<br />
70-80%. The normal onset of monsoon is during 1 st or 2 nd week<br />
of June and withdrawal is during 1 st or 2 nd week of October.<br />
The crops experience dry spells during second to fourth week of<br />
August to second week of September. The mean maximum/ and<br />
minimum temperature during crop season is 33.8ºC and 24.6ºC,<br />
respectively.<br />

Dryland agriculture problems<br />
The problems related to the domain districts are:<br />
Soil and land management<br />
●<br />
●<br />
●<br />
●<br />
The zone consists of shallow to very shallow black soils<br />
which limits available water holding capacity.<br />
Uneven topography leading to increased runoff.<br />
High cracking in Vertisols and soil moisture loss through<br />
evaporation.<br />
Soils are low in available N, P, organic matter and deficient<br />
in micronutrients resulting in poor crop yields.<br />
Crop production<br />
●<br />
●<br />
●<br />
●<br />
Aberrant weather/rainfall situation<br />
Lack of varieties suitable for rainfed groundnut based<br />
cropping systems.<br />
Lack of suitable implements for harvesting and threshing of<br />
various crops.<br />
Monocropping and poor crop diversification further reduces<br />
yield of crops.<br />
Socio-economic<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Fragmented and very small landholding causes problems<br />
in adopting farm machinery on hire basis for various<br />
agricultural operations.<br />
Poor resources (economic conditions), low level of literacy,<br />
high cost of inputs, lack of awareness and know-how with<br />
regards to available technology.<br />
Unavailability of timely and affordable credit facilities.<br />
Market risks<br />
Unavailability of labours during peak times and high labour<br />
wages.<br />
Significant achievements<br />
Rainwater management<br />
●<br />
For effective conservation and management of rainwater,<br />
cultivation of bunch groundnut in medium black soils at 30<br />
cm distance between rows having three rows on broad bed<br />
of 90 cm and furrow of 45 cm (BBF) for getting higher<br />
yield and net returns as well as to check runoff and soil loss.<br />
● Preparation of ridge and furrow or broad bed with 2<br />
rows (180 cm width) and furrow (60 cm) at 20 days after<br />
sowing in Bt cotton and application of plastic mulch (25<br />
micron)/straw mulch @ 5 t/ha at withdrawal of monsoon<br />
118
●<br />
●<br />
●<br />
in the month of September helped in obtaining higher<br />
productivity, maximum net returns as well as higher in-situ<br />
moisture conservation and rain water use efficiency under<br />
dry farming conditions. Apart from this, if the slope of<br />
field is around 1.5%, then growing of vegetative barrier of<br />
Dicanthium annulatum or Vetiver or Cenchrus cilliaris at<br />
interval of 7 meters checks runoff and minimizes soil loss<br />
and nutrient losses.<br />
For in-situ soil moisture conservation, application of<br />
murrum @ 40 t/ha or FYM @ 10 t/ha helped in increasing<br />
yield of groundnut and moisture conservation.<br />
Adoption of two to four interculture operations along with<br />
deep ploughing for higher yield of groundnut and maximum<br />
moisture conservation.<br />
Mulching with black plastic (50 micron) or groundnut shell<br />
or wheat straw mulch @ 7.5 kg/plant in guava resulted in<br />
higher soil moisture content and fruit yield.<br />
● Application of FYM @ 10 t/ha and kaolin @ 4% spray (400<br />
gm/10 litres water) during dry spell in groundnut and Bt<br />
cotton helped in getting higher productivity and maximum<br />
rain- and crop water use efficiency.<br />
●<br />
Farm pond of size 450 m 3 for 1 ha cultivable area provided<br />
one-irrigation of 5 cm and 7.5 cm to crop covering an area<br />
of 0.764 ha and 0.51 ha, respectively.<br />
Cropping systems<br />
●<br />
Groundnut + castor (3:1 or 6:1), groundnut and sesame<br />
(6:3), cotton + groundnut/green gram/black gram/sesame/<br />
cowpea (1:1), groundnut + pigeonpea (3:1), pearl millet +<br />
pigeon pea (2:1 or 4:1), sorghum + pigeonpea (1:1), castor<br />
+ cowpea/green gram (1:1) were found to be promising<br />
intercropping systems with increased yield and net return<br />
over their sole cropping.<br />
● Adoption of paired row planting of castor + green gram (2:1)<br />
and cotton + groundnut (2:1) was found to be economically<br />
viable for getting higher yield and net return.<br />
●<br />
●<br />
Intercropping of cotton (Bt Hybrid-8) with cowpea (Guj.<br />
cowpea-4) (1:1) gave higher yield and net return than sole<br />
cotton.<br />
In alley cropping system, sowing 16 rows of either<br />
groundnut (GG-2) or sorghum (CSH-5) in alley of perennial<br />
pigeonpea (ICPL-185)/ subabul (Hawaiian Giant) with 8.1<br />
m between two rows helped in obtaining higher equivalent<br />
yield of green fodder and monetary returns.<br />
Nutrient management<br />
● Application of 12.5-25-0 kg N-P-K/ha in groundnut, 80-<br />
40-0 kg N-P-K/ha in pearl millet, 90-30-0 kg N-P-K/ha in<br />
sorghum, 20-40-0 kg N-P-K/ha in pulses crop, 40-0-0 kg<br />
N-P-K/ha in desi cotton, 30-30-0 kg N-P-K/ha in castor<br />
119<br />
●<br />
and 50-25-0 kg N-P-K kg/ha in sesame crop resulted in<br />
sustained crop productivity and soil health.<br />
Application of 50% recommended NPK to groundnut<br />
and 100% recommended NPK to castor in groundnut +<br />
castor (3:1) intercropping resulted in higher groundnut pod<br />
equivalent yield and net returns.<br />
● Application of 80 kg N/ha to hybrid cotton and 25-12.5-0<br />
kg N-P-K to sesame in cotton + sesame (1:1) intercropping<br />
system gave higher seed cotton equivalent yield and net<br />
returns.<br />
●<br />
●<br />
●<br />
In crop rotation, application of 100% NPK (80-40-0 kg<br />
N-P-K kg/ha) only to pearl millet in groundnut-pearl millet<br />
crop rotation resulted in higher productivity under dry<br />
farming condition.<br />
Integrated nutrient management viz., application of 80 kg<br />
N + 10 t compost + 500 kg castor cake/ha along with biofertilizer<br />
(Azotobacter + PSB, each @ 1.25 kg/ha) in Bt<br />
cotton gave higher yield and net return besides improving<br />
soil fertility.<br />
Mulching of wheat straw or groundnut shell or farm waste<br />
@ 5 t/ha with 50% RDN to groundnut and 75% RDN to<br />
pearlmillet in groundnut – pearlmillet crop sequence<br />
resulted in improved soil fertility and crop productivity.<br />
● Application of 25% recommended NPK + compost @ 5<br />
t/ha + castor cake @ 500 kg/ha + Azotobacter and PSM<br />
in groundnut, sesame, pearlmillet, cotton and castor<br />
mono-cropping or crop rotation, preparation of enriched<br />
compost by recycling of crop residues with addition of bioinoculants<br />
and recycling of cotton stalk to prepare enriched<br />
compost within 120 days for sustaining soil fertility and<br />
crop productivity.<br />
Energy management<br />
●<br />
●<br />
●<br />
Use of tractor drawn deep tillage implements like disc<br />
plough, mould board plough and chisel plough conserved<br />
more moisture in the lower strata of soil and helped in better<br />
growth and yield of groundnut and cotton.<br />
Ploughing with tractor up to 20 cm depth in alternate furrow<br />
once in two years and application of FYM @ 5 t/ha + RDF<br />
helped in reducing the cost of ploughing and increased yield<br />
of groundnut.<br />
Improved tractor drawn seed-cum-fertilizer drill helped in<br />
maintaining optimum plant population and reduced the seed<br />
rate up to 20% compared to farmers’ practice (broadcasting<br />
and drilling).<br />

Technologies upscaled in convergence with various<br />
programmes<br />
Technologies have been upscaled on farmers’ fields in<br />
collaboration with KVKs, department of agriculture and<br />
department of watershed, Government of Gujarat. District wise<br />
contingency plans and various drought proofing action plans<br />
in the domain agro-climatic zones of the centre were upscaled<br />
with the help of GSDA. The centre, in collaboration with other<br />
AICRP schemes such as AICRP on groundnut, pearl millet,<br />
pulses, sesame, soybean and castor developed various improved<br />
varieties of crops viz., GG-2, GG-5, GG-9, GJG-32 bunch<br />
groundnut, GG-20, GG-22 semi spreading groundnut, GM-4<br />
greengram, GU-1, GU-2 blackgram, GC-5 cowpea, GT-3, GT-4<br />
sesame, GS-3 soybean and GCH-7 which helped to increase<br />
the productivity of these dryland crops. All these varieties<br />
were evaluated and upscaled through front line demonstrations<br />
in farmers’ fields, organising field day, etc. in the domain<br />
area through KVKs, ATMA, FTC and other line departments<br />
operating in the zone.<br />
The technologies for soil fertility management were upscaled<br />
through Soil Health Card program of GSDA. The NGOs, Cooperative<br />
societies and FPOs working in village level helped<br />
in upscaling of dryland technologies. The agromet advisories<br />
based on forecast given by State Meteorological Centre were<br />
regularly provided to the farmers in adopted villages. The farm<br />
pond technology, nala plugging, soil and water conservation<br />
measures such as deep ploughing, bunding and deep trenches in<br />
orchards were upscaled through watershed program.<br />
Impact of technologies<br />
Sowing of bunch groundnut in medium black soils at 30 cm<br />
distance between rows having three rows on broad bed of 90<br />
cm and furrow of 45 cm (BBF) gave higher pod yield (11%)<br />
as well as reduced runoff and soil loss (17%) as compared<br />
to flatbed system. If the slope of field is around 1.5%, then<br />
growing of Dicanthium annulatum/Vetivera/Cenchrus cilliaris<br />
as vegetative barrier at interval of 7 meters checks runoff and<br />
minimizes soil and nutrient losses. Application of murrum @ 40/<br />
FYM @ 10 t/ha increased pod yield of groundnut (16.0-16.5%)<br />
and moisture conservation (2.7-3.5%) than farmers’ practice.<br />
Mulching with black plastic (50 micron)/groundnut shell/<br />
wheat straw mulch @ 7.5 kg/plant in guava increased growth<br />
and fruit yield (9.22- 9.88 kg/plant) than crop without mulching<br />
(6.45 kg/plant). Application of FYM @ 10 t/ha and kaolin @<br />
4% spray (400 g/10 litres water) during dry spells increased the<br />
productivity of groundnut (1257 kg/ha) and Bt cotton (1924 kg/<br />
ha) with maximum rainwater use efficiency of 2.31 kg/ha-mm in<br />
groundnut and 3.82 kg/ha-mm in Bt cotton. Preparation of ridge<br />
& furrow and broad bed with 2 rows (180 cm width) and furrow<br />
(60 cm) at 20 days after sowing in Bt cotton increased seed<br />
cotton yield by 18 and 14%, respectively with higher rain water<br />
use efficiency as compared to flat sowing under dry farming<br />
conditions. Groundnut based replacement series of intercropping<br />
system viz., groundnut + castor (3:1), groundnut + pigeon pea<br />
(3:1), groundnut + sesame (1:1) increased productivity and net<br />
returns during normal rainfall and reduced risk during erratic<br />
and late rainfall. Bt cotton + groundnut/greengram/blackgram/<br />
sesame/cowpea (1:1) also increased productivity and net return<br />
during normal rainfall and reduced risk during erratic & uneven<br />
distribution of rainfall. In groundnut, pulses, cereals and other<br />
oilseed crops, application of recommended N-P-K kg/ha to<br />
groundnut (12.5-25-0), pearl millet (80-40-0), sorghum (90-<br />
30-0), pulses (20-40-0), desi cotton (40-0-0), castor (30-30-0)<br />
and sesame (50-25-0) increased crop productivity and sustained<br />
soil fertility under normal rainfall distribution. Application of<br />
75% recommended NPK to groundnut (1809 kg/ha) and 100%<br />
121
ecommended NPK to castor (1841 kg/ha) in groundnut + castor<br />
(3:1) intercropping system increased groundnut pod equivalent<br />
yield and saved 25% recommended NPK of groundnut. The<br />
integrated nutrient management viz., application of 80 kg N +<br />
10 t compost + 500 kg castor cake/ha along with bio-fertilizer<br />
(Azotobacter + PSB, each @ 1.250 kg/ha) in Bt cotton gave<br />
around 19% higher yield (2298 kg/ha) and net return beside<br />
improving soil fertility as compared to farmers’ practice (1924<br />
kg/ha). Adoption of INM practice (25% recommended NPK +<br />
compost @ 5 t/ha + castor cake @ 500 kg/ha + Azotobacter<br />
and PSM in groundnut, sesame, pearl millet, cotton and castor<br />
mono-cropping or crop rotation also increased crop productivity<br />
with sustained soil fertility.<br />

Brief history of the centre<br />
Ananthapuramu, is a southern district in Rayalaseema region<br />
of Andhra Pradesh. Although, the district is located in the rain<br />
shadow region and chronically drought prone, agriculture is<br />
the major economic activity. The annual average precipitation<br />
is 550 mm which is unevenly distributed. Low rainfall and<br />
high intensity rainfall events lead to greater erosion losses<br />
of soil and low crop yields. Agricultural Research Station,<br />
Ananthapuramu under Acharya N.G. Ranga Agricultural<br />
University, Andhra Pradesh was originally established as “Soil<br />
Conservation Research Centre” during 1964 at Rekulakunta<br />
village, Bukkarayasamudram mandal, Ananthapuramu district.<br />
All India Coordinated Research Project for Dryland Agriculture<br />
at Agricultural Research Station, Ananthapuramu has been in<br />
operation since 29 th September, 1971 and Operational Research<br />
Project (ORP) from 1986-1987 with an objective to conduct<br />
multi-disciplinary research on all aspects of dryland farming viz.,<br />
rain water management, cropping systems, farming systems,<br />
nutrient management, alternate land use, crop improvement,<br />
designing and testing of farm implements, etc. The domain area<br />
of AICRP for dryland agriculture comes under Scarce Rainfall<br />
Zone (SRZ) of Andhra Pradesh and zone covers two districts viz.<br />
Ananthapuramu and Kurnool. Presently, the above two districts<br />
were divided into four, namely; Anantapuramu, Sri Sathyasai,<br />
Kurnool and Nandyal districts, respectively.<br />
Agro-climatic zone characteristics<br />
The domain districts of the AICRPDA centre, Ananthapuramu<br />
are located in the Scarcity zone (NARP) of Andhra Pradesh;<br />

Significant achievements<br />
Rainwater management<br />
Rainfall is the critical input for crop production as much of the<br />
area is devoid of irrigation facilities. Proper management of<br />
time and space variations in rainfall is the key to better crop<br />
production. Under frequent dry spell situations, standard crop<br />
cultivation practices are not possible. Besides, research over<br />
the years revealed that the region experiences on average five<br />
runoff events per year which lead to 4-5 tons of soil loss per<br />
hectare. Conserving the rainwater reduces runoff and soil loss,<br />
consequently enhancing crop yields. The following are the<br />
significant findings over the years found efficient for effective<br />
rain water management.<br />
In-situ soil and water conservation practices increase soil water<br />
storage which helps crops to withstand moisture stress. These<br />
are simple and practiced by even individual small farmers.<br />
Suitability of the practice depends on the topography of the field.<br />
Based on extensive research, soil and water losses are reduced<br />
by adopting in-situ conservation practices like conservation<br />
furrows at 3.6 m intervals across the slope (25-30 days after<br />

sowing) with the receipt of rains. Among various types of bunds<br />
tested, contour bunds proved most effective in conserving soil<br />
and water. In an experiment on the effect of dikes in Alfisols for<br />
increasing rain water productivity in groundnut, it was found that<br />
higher mean pod yield (1003 kg/ha) was recorded with one dike<br />
after every 4 rows by conserving in-situ rain water effectively.<br />
To overcome the adverse effect of sub-soil compaction in red<br />
soils and to break the hard layer facilitating more intake of<br />
rainwater, deep ploughing with a chisel plough up to 40-60 cm<br />
depth at one metre interval once in 2 years was found useful in<br />
groundnut, castor and pigeonpea.<br />
Farm pond of 250 m 3 capacity (size of 10 x 10 m with 2.5 m<br />
depth) with side slopes of 1.5:1 is sufficient for catchment<br />
area of 2 ha. Soil + cement lining with 6:1 ratio was found<br />
very effective in reducing seepage losses. One supplemental<br />
irrigation of 20 mm to groundnut by sprinkler during dryspells<br />
at pod development stage enhanced the pod yield by 25-30%.<br />
Besides, to minimize the evaporation losses from farm pond, the<br />
bamboo mat material was found effective.<br />
Crops and cropping systems<br />
The cropping system based strategies for drought mitigation in<br />
the domain area of AICRPDA-Anantapuramu centre include<br />
growing crops and varieties that fit into changed rainfall and<br />
seasons. The groundnut varities; K-6, Dharani, Narayani,<br />
Kadiri Harithandhra, Visista and Kadiri Lepakshi are suitable<br />
for rainfed conditions due to their tolerance to drought, early<br />
duration and higher pod yield. Improved varieties recorded 10<br />
to 12% higher yield than the local varieties.<br />
Best yields of pigeonpea and castor were achieved when sown<br />
with groundnut as intercrop during June. Intercropping of<br />
groundnut + pigeonpea in 7:1or 11:1 or 15:1 row ratio instead of<br />
sole groundnut was found better. Optimum time for sowing of<br />
sole groundnut is June to July. If rainfall is delayed beyond July<br />
month, sowing of contingent crops such as sorghum, greengram,<br />
cowpea, pearl millet, horsegram and fodder sorghum is found<br />
profitable in the domain districts. Among different rainfed<br />
crops, pigeonpea, castor, clusterbean and sorghum can be<br />
grown as better alternate crops to groundnut in rainfed Alfisols<br />
as these crops gave maximum groundnut equivalent yield over<br />
years. Higher groundnut equivalent yield was recorded with<br />
groundnut + pigeonpea (8:1) which was on par with groundnut<br />
+ pigeonpea (14:2) intercropping system. Higher net returns<br />
were recorded with groundnut + pigeonpea (8:1) followed by<br />
groundnut + pigeonpea (14:2), korra + pigeonpea (8:1) and<br />
korra + pigeonpea (14:2).<br />
The fodder crops sown under delayed onset of monsoon, fodder<br />
maize and fodder sorghum were found efficient in fodder<br />
production. Fodder foxtail millet produced highest green fodder<br />
yield followed by fodder bajra and fodder maize. Fodder bajra,<br />
fodder sorghum and fodder maize are potential forage cereals<br />
because they can produce more quantity and quality fodder<br />
while also ensuring net monetary returns. Fodder cowpea and<br />
sunhemp are the next best suitable forage legumes under latesown<br />
conditions in the semi-arid Alfisols of the domain districts.<br />
Nutrient management<br />
Poor soil fertility due to erosion, low soil organic carbon (SOC),<br />
emerging multi-nutrient deficiencies, poor soil physical and<br />
biological environment for crop growth are limiting factors for<br />
productivity enhancement in this region. Hence, improving the<br />
soil fertility, carbon storage and soil health in the domain area of<br />
rainfed Alfisols is most needed to sustain the crop production.<br />
In this context, some recommended practices for improving<br />
infiltration and water retention in soils include diverse crop<br />
rotations with legumes and addition of farmyard manure<br />
(FYM), use of groundnut shells and other crop residues, green<br />
leaf manuring, etc.<br />
Integrated nutrient management<br />
Thirty seven years long-term integrated nutrient management<br />
experiment conducted at Agriculture Research Station,<br />
Anantapuramu revealed that 100% NPK and 100% NPK +<br />
ZnSO 4<br />
@ 50 kg ha -1 maintained higher mean pod yield (30.1<br />
and 27.5% respectively) than control over <strong>37</strong> years but INM<br />
practice of 50% NPK + groundnut shells @ 4 t ha -1 sustained<br />
higher pod yield and additionally sequestered 30.2% of SOC,<br />
which is a strong determinant of soil quality and agronomic<br />
productivity, especially under semi-arid environments. INM<br />
practices maintained positive balance of available N, P, K, S,<br />
Ca, Mg, Cu, Mn, Fe, Zn and B compared to sole application<br />
of chemical fertilizers over <strong>37</strong> years. Addition of carbon inputs<br />
through groundnut shells @ 4 t ha -1 is proved as a critical practice<br />
to maintain optimum SOC level in soil. Thus, the integration of<br />
groundnut shells along with chemical fertilizers emerged as the<br />
practice in the domain district to sustain groundnut pod yields<br />
and soil fertility for long-term under rainfed Alfisols in semiarid<br />
agro-ecosystem.<br />
Besides, on-farm generation of organic matter with appropriate<br />
policy support needs to be promoted to maintain soil health<br />
and crop productivity. In an attempt to solubilize native soil<br />
phosphorus in rainfed groundnut, soil test based fertilizer<br />
(STBF) + phosphatic bio-fertilizer consortium (PSB @ 5 kg ha -1<br />
+ PSF @ 5 kgha -1 + VAM @ 12.5 kg ha -1 ) were applied as basal<br />
dose at the time of sowing of rainfed groundnut. The results<br />
over 4 years revealed that STBF + P bio-fertilizer consortium<br />
increased groundnut yield by 17.5% over control.<br />
Foliar sprays for drought mitigation<br />
The approach of foliar spray of nutrients not only facilitates<br />
better plant growth and development, but also helps to alleviate<br />
125
different kinds of abiotic stresses like drought. This form of<br />
foliar spray does not address any specific nutrient deficiency<br />
but supplies a small amount of all nutrients to keep leaf growth<br />
lush. In an experiment conducted under AICRPDA at ARS<br />
Anathapuramu to mitigate mid-season drought in rainfed<br />
groundnut, 0.5% KNO 3<br />
as foliar spray at pod initiation and at<br />
pod development stage increased the pod yield and mitigated the<br />
dry spell effect on pod yield.<br />
Improving soil fertility in rainfed Alfisols<br />
The rainfed Alfisols are not only thirsty but also hungry. They<br />
are poor in soil nutrients as soil is subjected to fertility loss<br />
over years due to soil erosion. In this context, the local ITK -<br />
sheep penning is commonly used by local farmers to improve<br />
soil fertility. Sheep penning with one sheep per square meter<br />
significantly increased the pod yield of groundnut by 15%<br />
and haulm yield by 32% compared to control. Sheep penning<br />
significantly increased the available K 2<br />
O also in the soil and<br />
enhanced the soil fertility.<br />
Energy management<br />
In the backdrop of low and erratic rainfall, the sowing window<br />
is very narrow in the scarce rain fall zone. Hence, all the<br />
operations need to be done very quickly. Therefore, to cover the<br />
large area in less time and to save the cost of cultivation through<br />
labour wages, mechanization is essential. In this direction, the<br />
centre developed location-specific mechanization in the district<br />
for the benefit of farmers. Mechanical groundnut planters were<br />
recommended in the region to minimize delay in sowing, to<br />
optimise seed rate and ensure optimum plant population in<br />
groundnut. Among the different seed drills/planters tested for<br />
groundnut sowing, tractor drawn 8 row Ananta planter resulted<br />
optimum seed rate (100 kg/ha) and as well as plant population<br />
(33 plants per m 2 ). The mechanical seed drill developed by<br />
the centre is popular in the district. Department of Agriculture<br />
included the equipment in its subsidy scheme and that reflected<br />
the impact of technology in the region.<br />
An interculture implement (tractor drawn) was fabricated for<br />
intercultivation in groundnut and tested in the fields where<br />
Ananta planter was used for sowing. The implement was<br />
developed to bring complete mechanization in groundnut<br />
cultivation. Suitable interculture implement for castor crop<br />
was fabricated and tested in the field conditions. Aqua planter<br />
to supplement water in conjunction with groundnut sowing<br />
simultaneously when moisture is insufficient was developed.<br />
Groundnut + pigeonpea planter was designed and developed for<br />
sowing groundnut and pigeonpea in 8:1 ratio. A tractor drawn<br />
blade guntaka was designed to harvest groundnut in four rows<br />
simultaneously with minimum field losses. Groundnut fresh pod<br />
thresher that can thresh groundnut immediately after the harvest,<br />
and dry pod thresher were introduced in Ananthapuramu region<br />
to make the stripping operation easy and economical.<br />

Alternate land use systems<br />
The soils of the domain area are red sandy loam and shallow in<br />
depth, with undulating topography and poor soil fertility. In class<br />
IV lands with limitations with respect to depth, wetness, slope,<br />
runoff and soil texture, soapnut is the only tree that withstands<br />
harsh climatic (low rainfall) and slopy (8-15%) topographic<br />
soil conditions. Since, tamarind comes to fruiting only in well<br />
distributed rainfall years, to make the unproductive class IV<br />
lands productive with tamarind species, it should be integrated<br />
with pastoral system of Stylosanthes as horti-pastoral and sheep<br />
rearing component.<br />
Integrated farming systems<br />
Integrated farming system sustains the system productivity<br />
and farmer economic stability. The research revealed that, for<br />
a farm of 1 ha of land, groundnut as a kharif rainfed crop with<br />
sheep rearing (10 rams) for 4 months (November to February)<br />
improved the total net returns by 100 percent compared to crop<br />
alone. Besides, it provides 65 man days of employment after<br />
harvest of groundnut to the farmer. Similarly, under agri-horti<br />
system groundnut + amla integrated with ram lamb rearing<br />
is appropriate system in class IV land for semi-arid region of<br />
Ananthapuramu for the best use of available natural resources.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
Scarce rainfall zone in Andhra Pradesh faces frequent droughts.<br />
Risk involved in successful cultivation of rainfed crops depends<br />
on the frequency of drought occurrence within the season in the<br />
zone. Hence, technologies developed from AICRPDA centre<br />
Anantapuramu were successful at research station and the same<br />
were tested and demonstrated at farmer’s field and popularised.<br />
Such successful technologies were upscaled in convergence<br />
with Government programmes, NGOs and KVKs. The Centre’s<br />
technologies were adopted by the Department of Agriculture,<br />
Government of A.P., NGOs, KVKs and included in ANGRAU<br />
package of practices. Farm pond technology for rainwater<br />
harvesting and supplemental irrigation to rainfed groundnut<br />
found place in “Panta Sanjeevini” programme of Government<br />
of A.P. and was adopted by MGNREGA scheme. Mini tractor<br />
drawn Ananta planter and intercultivator were included by<br />
NABARD in subsidy scheme for farm machinery.<br />
Impact of technologies<br />
Farm pond technology is popular, climate resilient and<br />
successful in rainwater harvesting and mitigating the frequent<br />
dry spells in the zone. Filled farm pond water from runoff is<br />
used for mitigating dry spells by giving supplemental irrigation.<br />
This technology increased groundnut pod yield by 25% - 30%<br />
during drought years and reduced farmers distress. Subsoiling<br />
increased the yields in rainfed crops such as groundnut,<br />
pigeonpea and castor by 20-25% as compared to normal tillage.<br />
Resilient technology to mitigate dry spells enhanced the castor<br />
yield by 14 to 23% and rainwater use efficiency by 1.3 to 1.7%<br />
as compared to farmer’s practice. The technology was adopted<br />
by Department of Agriculture, Government of A.P. which is<br />
paying subsidy to farmers adopting this technology since 2014-<br />
15 onwards. Timely sowing can be done with aqua planter
developed by ARS, Ananthapuramu by using 10000 to 20000<br />
litre of water per acre depending upon the soil moisture content.<br />
Groundnut pod yield increased by 20-30%. By providing<br />
supplemental irrigation, Rs. 2030/ ha additional income was<br />
realized.<br />
Groundnut + pigeonpea inter cropping system is adopted in 70%<br />
in domain area. Farmers realized approximately Rs. 3000 – 3500<br />
per ha as additional income by adopting intercropping system.<br />
The adoption of drought management practices as a package in<br />
castor gave 35-50% higher yields over farmers practice with<br />
B:C ratio of 1.8. K-6, Dharani, Kadiri Harithandhra and Kadiri<br />
Lepakshi varieties are now recommended for rainfed conditions<br />
as they are tolerance to drought, early in duration and give higher<br />
yields. The improved varieties produce pod yield in a range of<br />
540-699 kg/ha as compared to 421 kg/ha.<br />
Soil test based fertilizer (STBF) technology saves cost of<br />
nutrients and also ensures balanced nutrition besides increasing<br />
pod yield of groundnut by 5% to 25%. Technology spread to<br />
70 - 80% in domain area. Foliar application mitigates the midseason<br />
drought and enhances the yield. The technology spread<br />
to 25-30 % in the domain area.<br />
Tractor drawn Ananta planter ensured timely sowing in large<br />
areas under optimum soil moisture conditions as the sowing<br />
window is narrow. This technology increased the cultivable<br />
dryland area for groundnut by 25 - 30% in domain area. An<br />
amount of Rs.1000/ha can be saved with tractor drawn Ananta<br />
intercultural implement compared to farmers practice. Tractor<br />
drawn groundnut + pigeonpea intercropping (8:1) planter for<br />
intercropping of groundnut + pigeonpea was adopted in 70%<br />
of the total groundnut area (7.0 lakh ha) and found useful for<br />
sowing of large area in short sowing window.<br />
Groundnut based IFS adopted in 20% of domain area has<br />
resulted in approximately Rs. 5000/ha increase in income<br />
among farmers. Practice of intercropping of groundnut with<br />
mixed pulses has been well adopted in slopy fields. This practice<br />
has been adopted in an area of 1.0 lakh ha.<br />
Way forward<br />
Frequent drought and extreme events continue to adversely<br />
impact production and productivity of rainfed crops in scarce<br />
rainfall zone of Andhra Pradesh. Further, these impacts are more<br />
pronounced due to climate change/ variability. In this context,<br />
future long-term and short-term research and management<br />
strategies suggested are: In the zone, water is the critical natural<br />
resource and managing rainwater in-situ or harvesting runoff<br />
water and recycling it is key to mitigate the chronic drought.<br />
Location-specific needs of soil & water conservation measures<br />
vis-a-vis changing rainfall scenario will address water issues<br />
much better. Adoption of improved varieties with real time crop<br />
planning (alternate crops in place of groundnut, contingent crops<br />
if monsoon is delayed) are important under changing climatic<br />
scenario.<br />
There is an increased need for weather based agro-advisory<br />
services (AAS) in farming activities for timely agricultural<br />
operations, improved crop yields, reduced cost of cultivation,<br />
need based changes in cropping patterns and for improved<br />
livelihoods. Micro-level climate risk-assessment in various<br />
crop production systems and specific management strategies<br />
to manage abiotic stresses in crop production systems are very<br />
much needed. Developing weather indices through agronomic<br />
research for real–time monitoring, assessment and contingency<br />
measures implementation is also envisaged.<br />
The main emphasis in scarce rainfall zone soils is to build the<br />
soil organic matter (SOM) for soil health restoration. Location<br />
- specific and need based crop residue management plan<br />
should be developed. The opportunity to promote adoption of<br />
various location specific integrated nutrient management (INM)<br />
practices is to be explored.<br />
There is a need for multipronged approach to maximize crop<br />
production for which site specific crop production techniques<br />
have to be adopted. Crop based approaches for drought mitigation<br />
include growing crops and varieties that fit into changed rainfall<br />
and seasons. In addition, adoption of intercropping systems, crop<br />
diversification, improved agronomic practices and agro-forestry<br />
systems helps to cope with any adverse event, and in particular,<br />
rainfall variability and drought. After recognizing the specific<br />
needs of rainfed dryland agriculture in the scarce rainfall zone of<br />
Andhra Pradesh, considerable efforts are necessary at all levels<br />
to sustain the momentum.<br />
The existing fragile rainfed agroecosystem in the scarce rainfall<br />
zone of Andhra Pradesh needs to be made more drought proof,<br />
more economical and sustainable under increasing frequency<br />
of droughts. The efficient use of rain water, soil and farm<br />
management practices in an integrated approach is both essential<br />
and a prerequisite. All India Coordinated Research Project for<br />
Dryland Agriculture (AICRPDA) Centre at Anantapuramu has<br />
developed several location specific technologies to cope with<br />
different situations including delayed onset of monsoon and<br />
mid-season drought. Key technologies among them are in-situ<br />
moisture conservation, rainwater harvesting in farm ponds and<br />
efficient utilization, INM, foliar sprays for drought mitigation,<br />
resilient crops and cropping systems, and contingency crop plans<br />
for the agro climatic zone. To achieve productivity enhancement<br />
in this fragile rainfed system, there is an urgent need to upscale<br />
these technologies through KVKs, NGOs, ATMA and other<br />
programmes of the governments which are aiming at farmers<br />
welfare.<br />

●<br />
Maize (grain)-sweet corn cropping system with supplemental<br />
irrigation from harvested rainwater in farm pond was found<br />
more remunerative with total net returns of Rs.159844 ha -1<br />
followed by maize (grain) – chickpea (Rs. 120433 ha -1 )<br />
and soybean- onion (Rs. 108394 ha -1 ). Seven irrigations<br />
(317 m 3 ) were given in sweet corn and onion (344.25 m 3 )<br />
at critical growth stages and one irrigation (39.25 m 3 ) was<br />
given to chickpea crop before flowering stage.
Crops and cropping systems<br />
●<br />
●<br />
Soybean-chickpea, maize-chickpea and green gramchickpea<br />
were grown with three land configuration<br />
treatments viz., farmers practice (flat sowing), broad bed<br />
furrow system (BBF) and raised bed furrow system (FIRBS)<br />
under rainfed condition. The maximum soybean equivalent<br />
yield (SEY) of 3285 kg ha -1 was recorded under FIRBSmaize-chickpea<br />
system followed by BBF-maize-chickpea<br />
system (3011 kg ha -1 ).<br />
Higher soybean equivalent yield SEY (6359 kg ha -1 )), net<br />
returns (Rs. 236150/ha) and B: C ratio (5.72) were recorded<br />
under soybean + maize (4:2)-berseem cropping system<br />
followed by soybean + pigeonpea (4:2) – wheat (4414 kg<br />
ha -1 & Rs. 127178 ha -1 , respectively).<br />
Nutrient management<br />
●<br />
●<br />
In the permanent manurial trial (PMT), based on the average<br />
of last 30 years, FYM 6 t ha -1 + N20 P13 gave higher seed<br />
yield of 1862 kg ha -1 . The study clearly indicated that a<br />
part of the inorganics can be substituted, thus substantially<br />
cutting the cost of cultivation. Application of 50% of RDF<br />
through inorganic fertilizer + 50% through organic manure<br />
gave higher seed yield (1383 kg ha -1 ) followed by RDF<br />
through inorganic fertilizer (1330 kg ha -1 ) and 10 t organic<br />
manure ha -1 (1306 kg ha -1 ).<br />
Application of micronutrients significantly improved the<br />
yield of soybean and chickpea. The highest seed yield<br />
of soybean (1654 kg/ha) and chickpea (2113 kg/ha) was<br />
recorded with RDF + Mo (soil application) 0.5 kg ha -1<br />
(ammonium molybdate as basal dose).<br />
Energy management<br />
● Among sowing techniques, higher seed yield (971 kg ha -1 )<br />
was recorded under raised bed and furrow system, which<br />
was at par with broad bed furrow and significantly superior<br />
to sweep blade type seed drill. Raised bed furrow system<br />
recorded 12.90% and broad bed furrow (BBF) 8.<strong>37</strong>% higher<br />
seed yield of soybean as compared to sweep blade type seed<br />
drill. The maximum output energy (14279 MJ ha -1 ) was in<br />
FIRBS followed by BBF (13694 MJ ha -1 ) and lowest was in<br />
sweep blade type seed drill (12639 MJ ha -1 ).<br />

Technologies upscaled in convergence with various<br />
programmes<br />
AICRPDA centre Indore developed many location-specific<br />
dryland technologies for the benefit of farmers. Many<br />
technologies were tested and demonstrated on farmers’ fields<br />
and popularised. Such successful technologies were up scaled in<br />
convergence with Govt. programmes, NGOs and KVKs.<br />
Impact of technologies<br />
The dryland technologies developed from AICRPDA - Indore<br />
have significantly improved the productivity of rainfed crops<br />
grown in scarce rainfall zone of Malwa. Farm pond technology<br />
and percolation tanks are the technologies which are more<br />
popular, climate resilient and successful in rainwater harvesting<br />
and mitigating the frequent dry spells in the zone. The impact of<br />
technologies was clearly visible with increase in productivity,<br />
yield stability and enhancing the livelihoods of farmers in<br />
the region. The impact of the technologies in terms yield<br />
enhancement and overall productivity improvement in the zone<br />
is presented below.<br />
Rainwater management<br />
Broad bed furrow system of planting to enhance productivity<br />
of rainfed soybean - The soybean was planted with 25 per cent<br />
reduced seed rate on BBF will enhance yield along with the<br />
improved physical property of soil, root development and water<br />
use efficiency. The excess rainwater collected in furrows takes<br />
care of crops during long dry spell and save crops from drought<br />
stress at pod filling and seed development stage of crop.<br />
Ridge furrow system of planting to enhance productivity of<br />
rainfed soybean - The soybean planted with 25 per cent reduced<br />
seed rate on R&F enhanced yield along with the improved<br />
physical properties of soil, root development and water use<br />
efficiency.<br />
Rainwater management through economically feasible water<br />
harvesting tanks in black soils - Storing excess rainwater in<br />
dugout farm ponds for utilization during the dry spells of monsoon<br />
season or for raising a subsequent crop was a promising way to<br />
improve the cropping intensity and crop productivities and to<br />
stabilize the farming in the Malwa region. As the programme<br />
got wide publicity through media and its demonstrational value/<br />
site, various farmers of the region contacted the project team<br />
to get acquainted with the project objectives and showed their<br />
willingness to construct water harvesting tanks in their fields<br />
if the team members provide technical guidance. In view of<br />
this, the team members provided technical guidance and helped<br />
the farmers to create water bodies in their own fields for better<br />
runoff management. Thus, the project could generate awareness<br />
among the farmers of the region to adopt and propagate this<br />
technology.<br />
Sweet corn with harvested water for higher income in<br />
deep black soils - Medium to small farmers from the villages<br />
nearer to the highways or which are well connected with local<br />
mandi of nearby city were practicing this technology. Micro<br />
irrigation methods like drip, sprinklers are getting popularized<br />
amongst farmers. Govt. of M.P. is providing for these systems<br />
at subsidized rate.<br />
Percolation tanks for ground water recharge - Percolation<br />
tank near the ridgeline was successful in retaining runoff and<br />
recharging the open wells, besides saving the adjoining fields<br />
from sheet erosion. This practice was gradually adopting by<br />
farmers.<br />
Enhancing water productivity in micro watershed -<br />
Construction of water harvesting tank on farmers’ field leads<br />
to availability of water for crop production. Once there is<br />
availability of water farmers raise crops and other components<br />
of farming system like poultry farming, fish rearing, crop<br />
diversification etc.<br />
Cropping systems<br />
Use of mulches to enhance productivity of rainfed crops<br />
- About 11 to 24 per cent higher production of soybean was<br />
obtained by using mulches which conserved soil moisture<br />
efficiently. 52 to 110 per cent higher production of rabi crop<br />
i.e., safflower was recorded as compared to without mulching.<br />
It is obvious that in soybean – safflower cropping system, by<br />
the using mulches the germination and production of crops were<br />
enhanced by conserving soil moisture effectively).<br />
Sunflower as contingent crop in very delayed sown conditions<br />
- This technology is important as contingent crop planning in<br />
very delayed onset of monsoon or failure of timely sown crop<br />
due to drought or any other adverse conditions. In such situation,<br />
the department of agriculture should have sufficient seed of<br />
sunflower and green gram to be provided to farmers. The plan<br />
further can be strengthened by seed bank concept in villages in<br />
which seed of such crops and their varieties be kept for use in<br />
abnormal weather conditions.<br />
Alternate crop for the region - Sweet corn and baby corn can<br />
be cultivated in limited area only and that too in areas, which<br />
are well connected to mandi and near high ways as shelf-life of<br />
these products is less and the produce should reach to sale outlet<br />
immediately after harvest. Medium to small farmers from the<br />
villages nearer to the highways or which are well connected with<br />
local mandi of nearby city, are practicing cultivation of sweet<br />
corn /baby corn. However, for larger area and general farmer the<br />
cultivation maize is good alternative to soybean.<br />
Nutrient management<br />
Potassium spray to combat mid-season drought stress in<br />
soybean - This practice is been recommended to reduce water<br />
133
loss via evapo-transpiration by application of potassium while<br />
crop is experiencing drought stress.<br />
Alternate land use systems and integrated farming systems<br />
Vegetable cultivation on the bunds of farm tank/water<br />
harvesting tank - Bottle gourd, sponge gourd, bitter gourd and<br />
Sem (Dolichos lablab) were planted on the bund of farm tank<br />
whose perimeter is of 160 m and the income thus generated<br />
was of Rs. 5661. The maximum WUE of 58.15 kg ha -1 cm -1<br />
was recorded by Sem (Balhar) (Dolichos lablab), This practice<br />
is currently adopted by 5-10% farmers in the region. It can be<br />
further upscaled in the zone with more extension efforts and<br />
demonstrations)<br />
Drum-stick (Moringa oleifera) /aonla (Phyllanthus embelica)<br />
+ soybean + pigeonpea - chickpea - Fruit crops viz., drumstick<br />
(cv. PKM-4) and aonla (cv. N-7) along with soybean (JS 93-05),<br />
pigeonpea (C-11) and soybean + pigeonpea (4:2 row ratio) found<br />
highly productive, profitable and economically viable. This<br />
practice is currently adopted by 5-10% farmers in the region. It<br />
can be further upscaled in the zone with more extension efforts<br />
and demonstrations).<br />
Way forward<br />
Though many technologies have been developed to improve<br />
the productivity of dry lands, a holistic approach on watershed<br />
basis needs to be promoted. Sustainable agriculture calls for<br />
development of land and water resources without deterioration<br />
of ecosystem and the solution for rainfed areas lies in watershed<br />
approach. The key attributes are conservation of rain water and<br />
optimization of soil and water resources in a sustainable and cost<br />
effective mode. The strategies required to harness the potential<br />
of dryland agriculture in Malwa region are<br />

Brief history of the centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture was started as a sub centre at Rewa in 1970-<br />
71. Later in the year 1984-85, the Centre was upgraded as<br />
main Centre. The Centre has the mandate to develop dryland<br />
agriculture technologies for Kymore Plateau and Satpura Hills<br />
zone of Madhya Pradesh with the domain districts of Rewa,<br />
Sidhi, Satna, Singrouli, Shahdol, Anooppur, Umaria, Panna,<br />
north eastern part of Katni, Jabalpur, Seoni and southern parts<br />
of Tikamgarh.<br />
Agro-climatic zone characteristics<br />
In general, the climate in this zone is sub-humid. Out of the total<br />
annual average rainfall of 1084 mm, the south-west monsoon<br />
contributes about 85% and post-monsoon about 15%. The<br />
normal onset of monsoon is during third week of June and<br />
normal withdrawal is during first week of October. The dry<br />
spells during crop season are experienced during August and<br />
September coinciding with flowering and grain formation stages<br />
of the major rainfed crops. The mean maximum temperature<br />
is 45.8 o C (May) and the mean minimum temperature is 2.9 o C<br />
(December/January).<br />

Rain water management<br />
Catchment command storage relationship studies carried out<br />
for, Khuthulia catchment, Rewa District. The highest monthly<br />
135
ainfall recorded was 752.60 mm in the month of August 2016<br />
and the highest yearly rainfall recorded was 1627.4 mm in the<br />
year 2016. In the above 10 years period, July (364.7 mm) and<br />
August (291.7 mm) months recorded maximum rainfall. The<br />
rainfall shows fluctuating nature during the ten years. The<br />
runoff for the study area is calculated using SCS- method for a<br />
period of 10 years i.e., 2008-2017. The calculated yearly runoff<br />
in mm for the years from 2008 to 2017 is 198.42, 61.38, 173.27,<br />
415.84, 622.56, 583.84, 107.32, 219.71, 791.34 and 294.57 mm<br />
respectively. The monthly runoff and yearly runoff is calculated<br />
for the period of 10 years using SCS-CN method. Minimum<br />
runoff 61.38 mm was observed in the year 2009 and maximum<br />
runoff was 791.34 observed in the year 2016 by using SCS-CN<br />
method. The correlation coefficients for daily, monthly and<br />
yearly runoff are 0.862, 0.973 and 0.952, respectively.<br />
The impact of life saving irrigation was 16.16% in wheat, 27.40%<br />
in chickpea, 24.54% in mustard and 19.58% in coriander when<br />
these crops were grown after rice. Wheat, chickpea, mustard and<br />
coriander were grown after soybean also showed variation in<br />
yield under control and life saving irrigation conditions. Grain<br />
yield of wheat was increased by 18.32% gram by 27.17%,<br />
mustard by 23.23% when grown after soybean.<br />
Gabion structure were found most suitable for gully erosion<br />
control and erosion through river bank. These structures are<br />
capable for filling large cavities and deep eroded soil from the<br />
fields. It protect the field from river flood and smoothen the<br />
cavities successfully. Masonary check dam was found suitable<br />
for storing the flowing water and recycling to the surrounding<br />
fields. About 10 farmers were benefited by applying pre-sowing<br />
irrigation to 33 acres of their land. It provide assurance of<br />
growing wheat and gram.<br />
Cropping systems<br />
Rice + pigeonpea intercropping gave maximum seed yield of<br />
22.85 q/ha and gross return of Rs. 122<strong>37</strong>/ha. Soybean variety JS<br />
76 -205 black seeded gave maximum grain yield of 21.85 q/ha<br />
with 90 kg seed rate/ha. Soybean varieties gave more yield when<br />
pre monsoon sowing was done. Mixed cropping of sorghum +<br />
kodo + pigeon pea + green gram + sesamum (Line sown) proved<br />
better. Chickpea + linseed (4:2 row ration) gave the higher yield<br />
individually as well as chickpea equivalent yield (CEY) up to<br />
10.91 q/ha . Among the pigeonpea based intercropping systems,<br />
pigeonpea + soybean (1:2) system found better. The genotype JS<br />
81-335 is gaining popularity amongst the farmers due to its high<br />
yield and early maturity (93 days). This variety is well suited for<br />
double cropping in rainfed areas so it may be recommended for<br />
commercial cultivation in Vindhya region of Madhya Pradesh.<br />
Nutrient management<br />
Application of 40 kg N/ha was considered optimum for rainfed<br />
rice. On the basis of long term study (17 years) in integrated<br />
Tiwari et al.<br />
136<br />
plant nutrient supply system, 100 % nitrogen through compost<br />
was superior in rice- wheat, blackgram – chickpea and rice +<br />
blackgram – wheat + chickpea sequences in terms of yield.<br />
Application of 50% N (urea) + 50% N (compost) + Azotobactor<br />
was the second best combination. Continuous application of<br />
organics helps in reducing tillage intensity and use of chemical<br />
fertilizers and improves soil environment. For the conservation<br />
of energy, low till farming strategy can be adopted in place of<br />
intensive cultivation which includes low tillage + weedicide +<br />
interculture. In a balanced nutrition study for soybean in kharif<br />
and chickpea in rabi , 20 kg N + 40 kg P with 10 kg ZnSo 4<br />
/<br />
ha was found superior for soybean with yield 3114 kg/ha and<br />
B:C ratio of 4.70. In case of chickpea under residual fertility<br />
condition, maximum seed yield of 2654 kg/ha was attained in<br />
the plot where 20 kg N + 40 kg P + 10 Kg ZnSO 4<br />
/ha was applied<br />
to soybean in the kharif season.<br />
Energy management<br />
Bullock drawn 2-row planter was demonstrated at Rithi village<br />
of Rewa region. It was found suitable for sowing soybean,<br />
wheat and gram. It covered 20% more sowing area as compared<br />
to desi plough sowing attachment. Because of its successful<br />
performance it was widely adopted by the farmers of Rithi and<br />
surrounding villages.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
The dryland technologies are being upscaled through department<br />
of agriculture, department of horticulture, KVKs, ATMA, etc.<br />
Impact of technologies<br />
Rainwater management<br />
The impact of life saving irrigation was 16.16% in wheat,<br />
27.40% in chickpea, 24.54% in mustard and 19.58% in coriander<br />
when these crops were grown after rice. Wheat, chickpea,<br />
mustard and coriander were grown after soybean also showed<br />
increased in yield with supplemental irrigation i.e. wheat yield<br />
by 18.32% , chickpea by 27.17%, mustard by 23.23%. Soybean<br />
with broad bed and furrow system enhanced yield along with the<br />
improved physical property of soil, root development and water<br />
use efficiency. Soybean, pigeonpea, blackgram, greengram and<br />
sesame are sown on ridges with the help of tractor drawn ridge<br />
and furrow planter. The ridges are formed 45 cm apart and 15<br />
cm wide on top. The technology of ridge and furrow conserves<br />
45% more moisture than flat bed sowing and retains it for a<br />
longer period. It increases the crop yield by 40-45% than farmers<br />
practice. Masonry check dam was found suitable for storing the<br />
flowing water and recycling to the surrounding fields. About 10<br />
farmers were benefited by applying pre-sowing irrigation to 33<br />
acres of their land.<br />
Cropping systems<br />
Soybean + pigeon pea system (3:2) gave net returns of Rs<br />
38100/ha. This system performs better in low rainfall region.<br />
The farmers are practicing this system in Rewa region in<br />
considerable area. Wheat + mustard (2:1) intercropping system<br />
gave wheat equivalent yield of 3010 kg/ha (2017 kg/ha of wheat<br />
+ 386 kg/ha of mustard) and farmers are practicing this system<br />
in Rewa region in considerable area.<br />
Planting of vetiver grass on field bunds will reduce soil loss by<br />
erosion and holds moisture for longer period two facilitate crop<br />
to survive in dry periods. Adoption of vetivar grass as live bunds<br />
in fields will reduce the soil loss and run off in the slope up<br />
to 2%, live barrier of khus grass reduce runoff and soil loss as<br />
compared to control which results in higher soil loss.
The land equivalent ratio (LER) of all the intercropping systems<br />
studied ranged from 1.32 to 1.65 indicating yield advantage with<br />
pigeonpea based intercropping systems. The maximum LER of<br />
1.65 was recorded with pigeonpea + soybean (1:2) intercropping<br />
system followed by pigeonpea + greengram system (1.64).<br />
Inter cropping of chickpea and coriander, both being important<br />
crops are readily accepted by the cultivators. And this system is<br />
spread to more than 40% in watershed area.<br />
Way forward<br />
The sustainable dryland agriculture calls for development<br />
of land and water resources in watershed approach. There<br />
is need to identify water-productive cropping systems and<br />
Tiwari et al.<br />
under-exploited crop and enhance abiotic stress tolerance of<br />
important dryland crops through conventional physiological<br />
approaches. The future research should focus on strategies<br />
for crop diversification, promoting nutrient and water use<br />
efficiency, improving and sustaining soil quality in rainfed agroeco-regions,<br />
crop and management practices and delineation of<br />
risk-prone zones, strategies for promoting balanced fertilization<br />
through site specific and integrated nutrient management and<br />
enhancing nutrient and water use efficiency through precision<br />

Indian Council of Agricultural Research (ICAR) started All<br />
India Coordinated Research Project for Dryland Agriculture<br />
(AICRPDA) in 1970 under the control of Dr. Panjabrao<br />
Deshmukh Krishi Vidyapeeth, Akola to solve location specific<br />
complexities through a cohesive, multi-pronged approach,<br />
emphasizing farmer’s point of view.<br />
Agro-climatic zone characteristics<br />
AICRPDA Centre, Akola is located in the campus of Dr.<br />
Panjabrao Deshmukh Krishi Vidyapeeth, the jurisdiction of<br />
which covers 11 districts of entire Vidarbha region. There are<br />
two revenue administrative divisions viz., Amravati and Nagpur.<br />
Akola is situated in the latitude 20°42’ N and longitude 77°02’<br />
E with the altitude of 305 m above mean sea level. Domain area<br />
of the project includes Akola, Buldana, Washim, Amravati and<br />
part of Yavatmal districts. It is classified under moist semi-arid<br />
Agro-ecological sub-region with medium deep clayey black soils<br />
(shallow loamy to clayey black soils), medium to high available<br />
water holding capacity (AWC) and LGP of 120-150 days<br />

Vidarbha region of Maharashtra state is mostly characterized by<br />
dryland farming. The climatic conditions of this region can be<br />
broadly described as semi-arid. The jurisdiction of Dr. Panjabrao<br />
Deshmukh Krishi Vidyapeeth is entire Vidarbha region. It is<br />
richly endowed with natural resources of varied types. Akola<br />
centre strives to solve location specific complexities through a<br />
cohesive, multi-pronged approach, emphasizing farmers’ point<br />
of view all the time. The region comprises eleven districts<br />
viz. Buldana, Akola, Washim, Amravati, Yavatmal, Wardha,<br />
Nagpur, Bhandara, Gondia, Chandrapur and Gadchiroli. It lies<br />
in between 17° 57’ - 21° 46’ N latitude and 75° 57’ - 80° 59’<br />
E longitude and covers an area of 97762.9 km2, which is 31.92<br />
per cent area of Maharashtra. The mean annual rainfall ranges<br />
from 700 mm at the west to 1700 mm at the east. The day length<br />
and temperature vary, giving a rise from north to south and<br />

rainfall from west to east. Thus, it gives rise to various agro<br />
climatic situations. This region mostly receives adequate rainfall<br />
in aggregate in monsoon period but suffers from vagaries of<br />
distribution and consequently the scarcity and semi-scarcity<br />
conditions. Some pockets in Khamgaon tahsil of Buldana district<br />
are drought prone. Monsoon sets in from 8 th June regularly and<br />
rains commence in between 18 th to 25 th June with highest rainfall<br />
during July and August and withdraw on 8 th October. However,<br />
rains are meagre after first fortnight of September. Total number<br />
of rainy days ranges in between 47 to 65.<br />
The coefficient of variation of monthly rainfall is 40 to 50% even<br />
for the wet month i.e. July indicating the uncertainty of rains<br />
during the season. The climatic conditions of the region can be<br />
broadly described as semi-arid type on annual basis. The region<br />
experiences sub-humid to humid conditions in monsoon season,<br />
semi-arid in winter season and arid in summer season. Vidarbha<br />
region has been divided into three agro-climatic zones based on<br />
rainfall, soil types and vegetation viz., Western Vidarbha Zone<br />
(Rainfall 700 to 950 mm), Central Vidarbha Zone (Rainfall 950<br />
to 1250 mm) and Eastern Vidarbha Zone (Rainfall
soils are calcareous, highly base saturated, fairly well drained,<br />
well supplied with potash, moderate to low in phosphate, but<br />
low in organic matter content and slightly alkaline.<br />
Soils of the Central Vidarbha are derived from basalt rock,<br />
black in colour and having varying depth depending upon their<br />
physiography. Inceptisols and Entisols are developed from<br />
basalt and they are very shallow to shallow.<br />

Major rainfed crops<br />
The major rainfed crops cultivated in the zone during kharif are<br />
cotton, soybean, pigeonpea, greengram, blackgram, sorghum<br />
and during rabi are chickpea and rabi sorghum. In western and<br />
central Vidarbha zone, predominant crops are cotton, sorghum,<br />
pigeonpea, greengram, blackgram, soybean, sunflower and<br />
maize. The rainfed cropping systems consist of sole cotton,<br />
sole soybean, Soybean + pigeonpea intercropping, Soybeanchickpea,<br />
Soybean-safflower, Greengram-safflower, Soybeansorghum<br />
which are dependent upon the residual soil moisture<br />
status of delayed SW monsoon winter rains. Agri-horticulture<br />
and silvi pasture systems are cultivated in pockets and especially<br />
in degraded land. Only cotton was found suitable for dry seeding<br />
as compared to other kharif crops viz. sorghum, greengram,<br />
blackgram and pigeonpea. Cotton should be sown before the<br />
onset of monsoon to get higher yield.<br />
Major shifts in cropping pattern /cropping systems for the<br />
last ten years<br />
●<br />

●<br />
●<br />
●<br />
●<br />
Cultivated area under soybean has considerably increased<br />
replacing area under cotton and sorghum.<br />
Soybean-chickpea evolved as a prominent and major<br />
sequence cropping system in Vidarbha region<br />
Soybean + pigeonpea (4:2)/(5:1)/(6:1) evolved as a<br />
prominent intercropping in soybean based system followed<br />
by the farmers of Vidarbha region.<br />
Cotton + pigeonpea (7:1)/(9:1) intercropping is evolved as<br />
a prominent intercropping in cotton based system followed<br />
by the farmers of Vidarbha region.<br />
Pigeonpea is most prominent intercrop in both cotton and<br />
soybean crop.<br />
Paddy is the major crop grown in eastern Vidarbha<br />
region which includes districts viz: Gondia, Gadchiroli,<br />
Chandrapur, Bhandara and some parts of Nagpur region<br />

●<br />
●<br />
●<br />
Climate vulnerability associated with biotic and abiotic<br />
stresses such as: early-mid-terminal droughts, prolonged<br />
dry spells, high rainfall events, heavy infestation of diseases<br />
and pests etc.<br />
High cost of inputs such as seeds, fertilizers, insecticides<br />
and weedicides.<br />
Scarcity of labour and high wages.<br />
Attack by wild animals and their management.<br />
Lack of resources for irrigation.<br />
Lack of awareness towards the adoption of new technologies/<br />
varieties among the farmers.<br />
Lack of farm mechanization.<br />
<strong>Issue</strong>s pertaining to the availability of electricity.<br />
Research initiatives since inception of the centre<br />
●<br />
●<br />
●<br />
●<br />
Climate resilient intercropping systems, double cropping<br />
systems, diversified cropping systems have been developed<br />
by the research centre to cope up with the issues of climate<br />
vulnerability<br />
Research centre has developed the low cost technologies<br />
for in-situ and ex-situ moisture conservation and rainwater<br />
management practices for increasing the productivity of<br />
rainfed crops.<br />
Dryland research centre has also developed technologies<br />
for nutrient management involving the integrated nutrient<br />
management strategies for sustainable soil health for<br />
maximizing the crop yields.<br />
National Innovations on Climate Resilient Agriculture<br />
(AICRPDA-N<strong>ICRA</strong>) and AICRPAM-N<strong>ICRA</strong> these two<br />
projects are implemented by the centre in various villages<br />
of the Akola District to disseminate and demonstrate the<br />
technologies of dryland agriculture for the farmers. Weather<br />
forecasting with agromet advisories are disseminated<br />
among the farmers of these villages to cope up with the<br />
climate vulnerabilities.<br />
Significant achievements<br />
Rainwater management<br />
●<br />
●<br />
In graded bunded field, for sustainable soil and water<br />
conservation and obtaining higher monetary returns it is<br />
recommended to plant and develop one vetiver line at the<br />
centre of adjacent graded bunds.<br />
Effect of land treatments for improving moisture regime<br />
in pulse based cropping system was studied at Akola,<br />
Achalpur, Washim, Yavatmal and Buldhana during 1991-<br />
92 to 1993-94. Opening of furrows (after two rows) at<br />
seeding or at 30 DAS is essential for improving moisture
●<br />
●<br />
status of the soil and in boosting crop yield in both contour<br />
sowing and sowing across the main slope in pulse based<br />
cropping system.<br />
Effect of land treatments on the yield of early cotton grown<br />
in shallow soils were studied at Akola and it is recommended<br />
to open furrow after every two rows at 30 DAS with a hoe<br />
for getting higher seed cotton yield in shallow soils.<br />
For obtaining higher cotton yield, monetary returns and<br />
improvement in soil fertility status, integrated application<br />
of 50% RDF (25:12.5:12.5 kg ha -1 N:P:K)+ FYM @ 5t ha -1<br />
+ PSB + Azotobactor and opening of furrow in each row at<br />
30-40 DAS is recommended under dryland condition.<br />
Cropping systems<br />
● In western vidarbha region, sorghum + pigeonpea (3:3),<br />
pigeonpea + soybean (1:2) and cotton + greengram (1:1)<br />
intercropping should be adopted in place of respective sole<br />
crops.<br />
●<br />
●<br />
●<br />
Intercropping of sorghum and pigeonpea in cotton was<br />
studied at Dryland Research Unit, Akola and recommended<br />
that, for getting higher monetary returns and to meet<br />
the requirement of food, fodder and fuel of the famers.<br />
Cotton + sorghum + pigeonpea + sorghum (6:1:2:1) four<br />
tier intercropping system is recommended under rainfed<br />
situation.<br />
For obtaining higher productivity and monetary returns,<br />
intercropping of Pearl millet + pigeonpea (1:1) at 30 cm<br />
row spacing in Inceptisols is recommended under dryland<br />
condition.<br />
For minimizing the risk in rainfed agriculture and obtaining<br />
higher yield and monetary returns, intercropping of cotton:<br />
soybean: pigeonpea: soybean (3:2:2:2) at 45 cm spacing is<br />
recommended.<br />
● For ease in sowing cotton + sorghum + pigeonpea +<br />
sorghum (3:1:1:1) recorded statistically at par net monetary<br />
return of Rs. 20032/- with Cotton + sorghum + pigeonpea<br />
+ sorghum (6:1:2:1) and it also recorded B:C ratio of 2.28<br />
with seed cotton equivalent yield of 871 kg ha -1 .<br />
●<br />
●<br />
For obtaining higher production, economic returns,<br />
convenience in sowing and interculture operations,<br />
intercropping of soybean + pigeonpea (4:2) with 45 cm<br />
spacing between the rows is recommended under dryland<br />
condition.<br />
Under dryland condition, for higher productivity and<br />
monetary returns, intercropping of vegetables cotton<br />
(cotton + cowpea or clusterbean) sown at 45 cm in 1:1 row<br />
proportion and application of 125% RDF (75:<strong>37</strong>.5:<strong>37</strong>.5<br />
NPK kg ha -1 ) in two split doses i.e. half dose of N , Full<br />
dose of P and K applied at the time of sowing to cotton +<br />

●<br />
●<br />
vegetable intercrops (<strong>37</strong>.5 : <strong>37</strong>.5 : <strong>37</strong>.5 NPK kg ha -1 ) and<br />
remaining half dose of nitrogen (<strong>37</strong>.5 kg ha -1 ) applied at 30<br />
DAS to cotton crop is recommended.<br />
For obtaining high monetary returns, soil moisture<br />
conservation on slopy field (up to 3% slope), it is<br />
recommended to take soybean-chickpea double cropping<br />
on 30% area of lower toposequence in place of sole cotton<br />
under cotton based cropping system in dryland condition.<br />
For obtaining higher system productivity and profitability,<br />
sowing of non Bt cotton + soybean (4:10)-safflower<br />
cropping system with tractor drawn seed drill and<br />
application of 45:55:30 kg ha -1 NPK to the Cotton +<br />
soybean (4:10) intercropping and 13.75:13.75:13.75 kg ha -<br />
1<br />
NPK to safflower is recommended for dryland condition of<br />
Vidarbha region.<br />
Nutrient management<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Application of 5 t FYM + 25 kg P 2<br />
O 5<br />
ha -1 as a basal dose and<br />
25 kg N ha -1 as top dressing after 30 days is recommended<br />
to Cotton + greengram (1:1) intercropping system as<br />
an Integrated Plant Nutrient Supply (IPNS) system for<br />
sustainable fertility and productivity of soil in drylands.<br />
Trial on green leaf manuring in sorghum, sunflower and<br />
pigeonpea (Alley cropping) was carried out at Akola and it<br />
was observed that Leucaena loppings @ 3.5 t ha -1 each year,<br />
if added for two years, curtail the fertilizer requirement and<br />
improve the soil health. After two years, there is no need<br />
of fertilizer for sunflower and pigeonpea crops. However,<br />
70 per cent yield over recommended dose of fertilizer is<br />
noticed in case of sorghum when Leucaena loppings @ 3.5<br />
t ha -1 was added.<br />
Studies on the effect of Leucaena loppings alone and in<br />
combination with fertilizers on soil properties and yield<br />
of seed cotton (AHH-468) were conducted at Akola and<br />
results revealed that combined use of organics and chemical<br />
fertilizers is more effective in increasing yield. Use of<br />
Leucaena loppings (4.5 t ha -1 ) reduced recommended dose<br />
of fertilizers by 50%. Alley width of 15 m with 4 rows of<br />
Leucaena each at 45 x 45 cm is proposed in alley cropping.<br />
Leucaena hedge rows act as vegetative barriers for soil and<br />
water conservation.<br />
Experiments on the effect of Leucaena loppings alone<br />
and in combination with fertilizer on growth and yield<br />
of sorghum were conducted and it is recommended that,<br />
Leucaena loppings @ 4.5 t ha -1 and 3/4 th recommended<br />
fertilizer dose be applied to kharif hybrid sorghum for<br />
obtaining similar net monetary returns as that obtained with<br />
the recommended doses of fertilizer.<br />
In medium deep soils where available zinc status is low to<br />
medium, hybrid sorghum crop should be fertilized with 5
kg zinc ha -1 (25 kg ZnSO 4<br />
ha -1 ) along with recommended<br />
dose of fertilizer.<br />
● Pigeonpea crop be fertilized with 20 kg P (46 kg P 2<br />
O 5<br />
ha -1 ) along with 5 t FYM and 1.5 kg phosphorus solubilizing<br />
bacteria (PSB) per hectare for economy in chemical<br />
fertilizer.<br />

●<br />
Application of 4 t FYM and 100:50:50 kg N, P 2<br />
O 5<br />
and<br />
K 2<br />
O ha -1 is recommended to variety Amber popcorn maize,<br />
for obtaining higher grain and fodder as well as monetary<br />
returns under dryland conditions.<br />
For obtaining higher yield and economic returns in zinc and<br />
boron deficient vertisols, it is recommended to apply 25 kg<br />
Zinc sulphate and 5 kg Borax ha -1 along with 50:25:00 NPK<br />
kg ha -1 to rainfed American cotton. The seed cotton yield<br />
(1062 kg ha -1 ) obtained with improved practice is 23 per<br />
cent higher under 125% RDF + 25 kg/ha ZnSO 4<br />
+ 5 kg / ha<br />
Borax as compared to 100% NPK (50:25:00 NPK kg/ha)<br />
only (861 kg/ha) The net returns with improved practice is<br />
19 per cent higher than the recommended dose. This also<br />
helps in quality of the cotton in general and improves the<br />
soil fertility status in vertisols.<br />
● The improved practice gives higher seed cotton yield (887<br />
kg/ha) with INM practice (50% recommended N (25 kg/<br />
ha) through green leaves of gliricidia + 50% N through<br />
urea (25 kg/ha) + 25 kg P 2<br />
O 5<br />

O/ha) along<br />
with seed treatment, which is 15% higher as compared to<br />
recommended dose i.e., 50:25:0 NPK kg/ha (750 kg/ha)<br />
with 28% higher net returns. The INM practice helps in<br />
improvement of fertility status of soil, especially nitrogen<br />
and potassium status of soil since 1 ton of gliricidia adds<br />
21 kg N and 18 kg K annually. The loppings of gliricidia<br />
serve as mulch, thus conserve soil moisture, further helps in<br />
improving soil physical and biological properties on a long<br />
term.<br />
●<br />
The yield of soybean (1760 kg/ha) with INM practice is<br />
8 per cent higher as compared to recommended dose i.e.<br />
30:75:00 NPK kg/ha (1618 kg/ha) with 13 % higher net<br />
returns. The INM practice helps in improvement of fertility<br />
status of soil, especially nitrogen and potassium status<br />
of soil since 1 ton of gliricidia adds 21 kg N and 18 kg<br />
K annually besides improving soil physical and biological<br />
properties.<br />
Tillage and nutrient management<br />
●<br />
In rainfed condition for sorghum crop, minimum tillage (one<br />
hoeing followed by one hand weeding) with 20 kg nitrogen<br />
through inorganic fertilizer+ 20 kg N through FYM (3.80 t<br />
ha -1 ), 40 kg P 2<br />
O 5<br />
and 40 kg K 2<br />
O as basal dose and remaining<br />
20 kg nitrogen through inorganic fertilizer + 20 kg through<br />
gliricidia (3 t ha -1 , at 30 DAS) is recommended for higher<br />

The efficiency of Planofix hormone (NAA) on the seed<br />
cotton yield conducted for three years revealed that two<br />
sprays of Planofix at the commencement of flowering and<br />
at 50% flowering should be given in order to get higher seed<br />
cotton yield of variety L-147.<br />
While studying optimum plant population of pigeonpea<br />
Hy-2 for three years, it was observed that spacing of 60 x<br />
30 cm (55555 plants ha -1 ) recorded the highest yield.<br />
Pigeonpea should be sown in 2 nd fortnight of September<br />
with a spacing of 45 to 60 cm x 30 cm. Wider row spacing<br />
(60 cm) may be adopted for deeper soils<br />
Sorghum could be grown in all types of soil with<br />
recommended dose of fertilizers. Cotton could be grown<br />
on class II soils (60 cm) with recommended fertilizers.<br />
However, long duration varieties of pigeonpea should not<br />
be grown on shallow soils (20 cm). Pigeonpea should be<br />
fertilized with recommended dose of fertilizer on class II<br />
and class III soils.<br />
Sowing of castor on the onset of monsoon is recommended<br />
for Akola district. However, sowing could be extended up<br />
to middle of August under contingency. Sowing of castor<br />
in second week of August is recommended for Buldhana<br />
district and it could be delayed up to September when<br />
contingency arises. Spacing of 90 x 40 cm is recommended<br />
for castor at both the places<br />
Requirement of P for hybrid sorghum (CSH-9) on Vertisols<br />
were studied at Akola, Achalpur, Washim and Buldhana and<br />
results showed that, dose of 25 kg P 2<br />
O 5<br />
ha -1 in deep heavy<br />
soils and 40 kg P 2<br />
O 5<br />
in medium deep soils is recommended<br />
to hybrid sorghum (CSH-9).<br />
Cotton variety AKH-081 performed better in shallow soils<br />
(< 30 cm) under rainfed condition.<br />
Technologies developed<br />
Rainwater management<br />
●<br />
In-situ moisture conservation through topo sequence<br />
based cropping: In cotton (Rajat) on fields (up to 3%<br />
slope), in the lower toposequence covering about 30%<br />
area is replaced by soybean (PKV-1), which is followed by<br />
chickpea (ICCV-2) in rabi. This enables double cropping in<br />
lower toposequence. For demarcation of such area, Vetiver<br />
key line is established in the beginning of the system, which<br />
also helps in moisture conservation.<br />
● Continuous Contour Trenches for moisture<br />
conservation and establishment of agri-horti systems:<br />
The technology of continuous contour trenches (CCT)
comprise of demarcation of contour lines with dumpy level<br />
or contour marker on the selected land. Once the contour<br />
lines are drawn, parallel to these contour lines, continuous<br />
contour trenches of 60 x 30 cm are excavated such that the<br />
upper fertile soil is collected on upstream side and below<br />
murrum is spread at downstream side in the form of bund<br />
with suitable berm (space between trench and bund). Then<br />
the fertile soil is used to fill mound in the trench on desired<br />
spacing for example, in this technology, 5 to 6 m between<br />
the plants. The mound is used for planting of custard apple<br />
and hanuman phal at 5 m interval and remaining trench is<br />
left for in-situ rainwater conservation. For the first 5 years<br />
of establishment of the fruit trees, the interspaces between<br />
adjacent trenches are used for cultivation of greengram and<br />
blackgram for efficient utilization of land and resources.<br />
There is also scope for cultivation of soybean, horsegram,<br />
cowpea and other short duration crops.<br />
● Conservation furrow and integrated nutrient<br />
management for increasing cotton productivity: The<br />
technology comprises of American cotton sown at 60 x<br />
30 cm with bullock drawn 3 type seed drill. The seed rate<br />
of cotton is 15 kg ha -1 . The improved practice includes<br />
application of 50% recommended N (30 kg ha -1 ) through<br />
FYM + 50% N through urea (12.5 kg ha -1 ) + 30 kg P 2<br />
O 5<br />
ha -1 + 30 kg K 2<br />
O ha -1 in rainfed cotton. Earlier, the seeds<br />
of cotton are treated with bio-fertilizers (Azatobacter and<br />
PSB @ 25 g/kg seed). The half dose of N (12.5 kg ha -1 ),<br />
entire dose of P and K are applied as basal. The remaining<br />
half dose of N (12.5 kg ha -1 ) is supplied through chemical<br />
fertilizer urea applied 30 DAS manually near the plant by<br />
ring method.)<br />
●<br />
Rainwater harvesting through farm pond: Based on<br />
the runoff from two catchments, the capacity of the farm<br />
ponds have been decided. Accordingly, the location for<br />
construction of the farm ponds had been chosen and<br />
the dimensions were decided and construction of two<br />
farm ponds for two different catchments was done. Farm<br />
pond 1, capacity-2750 cum (size, 45 x 27 x 3 m) is<br />
having embankments on all sides however farm pond 2,<br />
capacity-<strong>37</strong>0 cum (size, 18 x 11 x 3 m) have embankments<br />
on two sides only and other two sides are without<br />
embankments which will acts as inlets for sheet flow in the<br />
pond. The sheet flow is to be passed from the vegetative key<br />
lines surrounding the sides of the farm pond. These farm<br />
ponds are having pipe outlets located at suitable places for<br />
safe disposal of the excess water when the farm ponds are<br />
filled to its fullest capacity. The farm ponds are not lined.<br />
The berms are provided on all sides of the farm ponds for<br />
easy access and for stability of the embankments.<br />

Pearlmillet + pigeonpea (1:1) intercropping system in<br />
black soils of Western and Central Vidarbha region:<br />
(The improved technology comprises of Pearl millet +<br />
pigeonpea intercropping system in 1:1 row proportion.<br />
Pearl millet (ICTP 8203) and pigeonpea (C 11) are sown in<br />
alternate rows at distance of 30 cm. The seed rate of pearl<br />
millet is 4 kg ha -1 and pigeonpea is 15 kg ha -1 and are sown<br />
with 3 type bullock drawn seed drill (Tifan /Sartah) with<br />
a basal fertilizer dose of 60:30 kg ha -1 of NP. Half of dose<br />
of N (30 kg ha -1 ) and entire dose of P is applied as basal with<br />
ferti cum seed drill. Remaining half dose of N (30 kg ha -1 )<br />
is applied through urea at 30 DAS. One weeding and one<br />
hoeing with bullock drawn hoe is done at 30 DAS.)<br />
Performance of cotton genotypes under HDPS with<br />
Soybean (6:6)-mustard strip intercropping system: (The<br />
improved practice includes sowing of high density (45 x<br />

and soybean strip sequenced with mustard at 45 x 15 cm<br />
spacing with recommended dose of fertilizer (40:20:20<br />
NPK kg ha -1 ) is recommended for dryland condition of<br />
Vidarbha region. The spacing for cotton crop is 45 x 15 cm<br />
whereas soybean is sown at 45 x 5 cm and mustard 45 x 15<br />
cm with seed rate of cotton (12.5 kg ha -1 ), soybean (<strong>37</strong>.5 kg<br />
ha -1 ) and mustard (3 kg ha -1 ).<br />
Intercropping of pigeonpea and soybean in cotton<br />
with varying planting geometry: For minimizing the<br />
risk in rainfed agriculture and obtaining higher yield<br />
and monetary returns, intercropping system of Cotton:<br />
soybean: pigeonpea: soybean (3:2:2:2) at 45 cm spacing is<br />
recommended.<br />
Up scaling of Cotton + sorghum + pigeonpea + sorghum<br />
(6:1:2:1) intercropping system: For ease in sowing and<br />
getting monetary returns comparable to risk minimizing<br />
intercropping system 6:1:2:1 (cotton : sorghum : pigeonpea:<br />
sorghum) and to meet the requirements of food, fodder and<br />
fuel of the farmers, 3:1:1:1 (cotton: sorghum: pigeonpea:<br />
sorghum) is recommended under dryland condition).<br />
Nutrient management<br />
●<br />
Nutrient management through greengram incorporation<br />
in cotton: Cotton (Rajat) is sown with 60 cm row spacing.<br />
Without hampering the plant population of cotton, one row<br />
of greengram (Kopergaon) is sown between two rows of<br />
cotton. At the same time 50% N (FYM) +50 percent N<br />
(urea) is applied to cotton. After picking of greengram pods,<br />
the biomass of greengram is incorporated into the soil by<br />
hoeing through interculture operations.)<br />

Nutrient management in rainfed cotton on Vertisols:<br />
The technology includes basal soil application of Zn @ 25<br />
kg Zinc Sulphate and B @ 5 kg Borax/ha along with 30<br />
(50 per cent dose of N): 30:00 NPK kg ha -1 with ferti cum<br />
seed drill. In this case, 60 kg ha -1 of N and 25 kg of P are<br />
recommended which is 10 kg ha -1 and 5 kg ha -1 , more than<br />
the recommended dose of N (50 kg ha -1 ) and P (25 kg ha -1 )<br />
respectively. Remaining dose of N i.e., 30 kg ha -1 is applied<br />
at 30 DAS.)<br />
Integrated nutrient management in soybean in black<br />
soils: The technology comprises of basal application of<br />
50% recommended N (15 kg ha -1 ) through green leaves of<br />
glyricidia + 50% N through urea (15 kg ha -1 ) + 75 kg P 2<br />
O 5<br />
+ 25 kg K 2<br />
O ha -1 along with seed treatment of bio-fertilizers<br />
(Rhizobium and PSB @ 25 g/kg seed). The fresh toppings<br />
of glyricidia are applied manually in between the rows of<br />
soybean. The seed rate of soybean is 75 kg ha -1 and spacing<br />
is 45 cm in between rows and 10 cm intra rows.)<br />
Integrated nutrient management in cotton in black<br />
soils: The improved practice includes application of 50 per<br />
cent recommended N (25 kg ha -1 ) through green leaves of<br />
glyricidia + 50% N through urea (25 kg ha -1 ) + 25 kg P 2<br />
0 5<br />
/ha + 25 kg K 2<br />
O ha -1 in rainfed cotton (American cotton).<br />
Earlier, the seeds of cotton are treated with bio-fertilizers<br />
(Azotobacter and PSB @ 25 g/kg seed). The half dose of N<br />
(25 kg ha -1 ) entire dose of P and K are applied as basal. The<br />
remaining half dose of N is supplied through fresh toppings<br />
of glyricidia, which are applied manually in between the<br />
rows of cotton at 30 DAS. The seed rate of cotton is 10 kg<br />
ha -1 and spacing is 60 cm in between rows and 30 cm intra<br />
rows.)<br />
● Performance of intercrops and levels of fertilizers in G.<br />
hirsutum cotton (AKH- 9916) under rainfed condition:<br />
The improved practice gives higher seed cotton equivalent<br />
yield of 2464 kg ha -1 for cotton + cowpea (1:1) whereas 2442<br />
kg ha -1 for cotton + clusterbean (1:1) cropping system with<br />
50% N + 100% P and K applied through inorganic fertilizer<br />
at the time of sowing to intercrops and 50% nitrogen after<br />
one month to cotton crop only. This intercropping systems<br />
of cotton + cowpea (1:1) and cotton + clusterbean (1:1)<br />
provide higher crop profitability (Rs. 363.35/- and Rs.<br />
366.47/- ha -1 day -1 respectively) and system profitability<br />
(180.18 and 181.73 Rs. ha -1 day -1 respectively) with higher<br />
values of crop productivity (13.61 and 13.49 kg ha -1 day -1<br />
respectively).<br />
Tillage and nutrient management<br />
● Tillage and nutrient management for resource<br />
conservation and improving soil quality: The improved<br />
practice includes sowing of sorghum crop with low tillage<br />
Chorey et al.<br />
144<br />
i.e one hoeing followed by one hand weeding with 20 kg<br />
nitrogen through inorganic fertilizer + 20 kg through FYM<br />
(3.8 t ha -1 ), 40 kg P 2<br />
O 5<br />
and 40 kg K 2<br />
O as basal dose and<br />
20 kg nitrogen through inorganic fertilizer + 20 kg through<br />
glyricidia (3 t ha -1 ) is recommended for overall resource<br />
conservation i.e, higher water use efficiency, enhanced soil<br />
fertility and higher grain and fodder yield.)<br />

Early season drought:<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Adoption of risk resilient cotton and soybean based<br />
intercropping systems such as cotton+greengram (1:1),<br />
cotton + cowpea (1:1), cotton+clusterbean (1:1), soybean +<br />
pigeonpea (4:2), soybean + pigeonpea (6:1) as preparedness<br />
to cope up with drought situations instead of sole cropping<br />
of cotton and soybean for assured and sustainable crop<br />
production.<br />
Sowing of cotton and soybean on broad bed furrow through<br />
BBF planter for in-situ moisture conservation and to cope<br />
up with moisture stress during early season drought.<br />
Raising of cotton seedlings in polythene bags for<br />
transplanting when sufficient moisture is available after<br />
receipt of rains can be practiced to compensate loss in plant<br />
stand with seedlings of similar age.<br />
If moisture stress occurs at very early stage i.e. within a<br />
week to10 days after sowing, it is recommended to resow<br />
with subsequent rains for better plant stand.<br />
In case of failure of kharif crops, prefer sowing of photo<br />

insensitive crops such as pearlmillet, sunflower, sesame and<br />
pigeonpea once adequate rains are received.<br />
Gap filling to be done by watering 7 to10 days after sowing<br />
when crop stand is less than 75%.<br />
Interculture for removal of weeds and creating soil mulch.<br />
Open conservation furrows in each row in cotton and<br />
soybean by tying a rope to hoe and furrow across the slope<br />
for in-situ moisture conservation.<br />
In Pigeonpea, gap filling either with sesame or maize.<br />
In Sorghum, adopt thinning to maintain optimum plant<br />
population.<br />
Avoid applying fertilizer till sufficient moisture is available<br />
in soil.<br />
Mid season drought<br />

Take up repeated interculture to remove weeds and create<br />
soil mulch to conserve soil moisture.<br />
If severe moisture stress, ratooning or thinning may be done<br />
in kharif sorghum and pearlmillet.<br />
Open conservation furrows in each row in soybean and<br />
cotton for in-situ moisture conservation by tying a rope to<br />
hoe during hoeing.<br />
Open alternate furrows in row crops such as soybean or<br />
furrows for every 6-8 rows of pigeonpea with Balaram<br />
plough in medium to deep soils.<br />
Foliar spray of 2% urea solution at flowering stage in cotton<br />
to supplement nutrition during mid season drought.<br />
Foliar spray of 19:19:19 mix water soluble fertilizer at pod<br />
initiation stage in soybean to supplement nutrition during<br />
mid season drought.<br />
Avoid top dressing of fertilizers until receipt of rains.<br />
Adopt surface mulching with crop residue or tree loppings<br />
of Glyricidia wherever possible.<br />
Terminal drought<br />
●<br />
●<br />
●<br />
●<br />
●<br />
Provide life saving or supplemental irrigation, if available<br />
preferably through sprinkler or drip irrigation at pod<br />
development stage in soybean and at boll development stage<br />

Impact of technologies<br />
If the harvested farm pond water is used for protective irrigation<br />
to soybean crop during kharif, then 38.56% yield increase was<br />
observed as compared to without irrigation treatment. Similarly<br />
for chickpea the yield increase was 31.84 % in protective<br />
irrigation treatment as compared to non-irrigated treatment.<br />
Vegetative barriers as interbund enables to achieve 11.23%<br />
increase in yield of soybean in interbund treatment followed<br />
by vetiver key line 10.39% and graded bund (4.20%) over<br />
control i.e., no barrier treatment. Cotton + sorghum + pigeonpea<br />
+ sorghum (3:1:1:1) gives net income of Rs. 20000/ha with<br />
seed cotton equivalent yield of 871 kg /ha. Cotton + soybean +<br />
pigeonpea+ soybean (3:2:2:2) intercropping gives 36% higher<br />
cotton seed equivalent yield (15<strong>37</strong> kg/ha) with net returns Rs.<br />
30,000 /ha compared to sole cotton (976 kg/ha), net monetary<br />
returns (Rs. 14956 /ha). Adoption is 10% area in the domain<br />

gives 56% higher pearl millet equivalent grain yield (4018 kg/<br />
ha) with net returns of Rs. 30,000/ha and B:C ratio of 3.29 as<br />
compared to sole pearl millet yield (958 kg/ha). This system also<br />
enhances resource use efficiency and improves soil fertility due<br />
to pigeonpea as intercrop. Adoption is 5-10% area in Buldhana<br />
district. Soybean + pigeonpea (4:2) intercropping system gives<br />
36 % increase in soybean equivalent yield (3277 kg/ha) with<br />
net returns of Rs.72,792/-ha, B:C ratio 4.31 and LER 1.47 as<br />
compared to sole soybean yield of 2058 kg/ha, net monetory<br />
returns of Rs. 36,413 and BC ratio of 2.65. This system also<br />
helps in covering the land during early stages, conserves<br />
moisture and also improves the soil fertility status. Adopted in<br />

Adopted in 10% area of domain districts.<br />
Balanced nutrition in cotton in deep black soils (60 kg N + 30<br />
kg P + 25 kg Zinc sulphate + 5 kg Borax) gives 23% higher<br />
seed cotton yield (1062 kg/ha) as compared to recommended<br />
dose of NPK (50:25:00 kg/ha). Incorporation of greengram in<br />
cotton, over period of time improves soil physical condition and<br />
fertility status resulting in higher productivity and profitability<br />
(net returns of Rs. 12,000/ha) and adopted in more than 50%<br />
of cotton cultivated area in the domain districts. Micro site<br />
improvement with Continuous Contour Trenches (CCTs) helps<br />
in efficient in-situ moisture conservation, which further help in<br />
better establishment, survival and performance of the custard<br />
apple and hanuman phal. In the initial 5 years of establishment<br />
of the fruit trees, the inter space was used for cultivation of short<br />
duration pulse crops. Viz., greengram and blackgram, resulting<br />
in efficient utilization of resources. The CCTs also helped in<br />
increasing ground water recharge as compared to square pit<br />
plantation.<br />
Way forward<br />
In the era of climate change, multiple abiotic stresses are the<br />
key challenges for future dryland crops. In the same season,<br />
crops experience drought in the early part and water logging in<br />
the later growing period due to erratic rainfall distribution. The<br />
centre aims to integrate other components like natural resources,<br />
and livestock and also to identify models for sustainable<br />
integrated farming systems to cope with drought situations. The<br />
research center works on research areas to increase agricultural<br />
productivity, especially in rainfed areas focusing on integrated<br />
farming and improved water use efficiency which is the current<br />
need for the development of such technologies for marginal and<br />
small farmers of rainfed regions. Therefore, a paradigm shift in<br />
future research is necessary.<br />
The research focus needs to be on the following aspects:<br />
1. Diversified farming systems to cope with the uncertainty of<br />
weather conditions imposing multiple risks during the crop<br />
season.<br />
147
2. Development of rainfall-runoff relationship in a changing<br />
climate scenario for the planning of rainwater management<br />
structures and thereby the crop planning based on the<br />
availability of harvested rainwater.<br />
3. Soil health management through conjunctive use of organic<br />
and inorganic sources of nutrients and synergizing resource<br />
conservation and carbon sequestration.<br />
4. Integrated approach in resource allocation to field crops,<br />
horticulture, and livestock depending upon the resource<br />
endowments and proportional contribution.<br />
Chorey et al.<br />
5. Intensification of high-yielding varieties of different crops<br />
with special emphasis on minor millets.<br />
6. Exploring the potential of marginal lands with highly<br />
productive alternate land use system modules.<br />
7. Evolving good agronomic practices for inclusion in the<br />
package of practices of respective field crops.<br />

Brief history of the centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Centre at Kovilpatti was started as a main Centre at<br />
Agricultural Research Station, Kovilpatti in 1971. This Centre<br />
is intended to cater the needs of the rainfed black soil areas<br />
which occupy a major portion of the southern districts of Tamil<br />
Nadu viz., Tuticorin, Tirunelveli, Virudhunagar, Madurai and<br />
Ramanathapuram districts.<br />
Agro-climatic zone characteristics<br />
AICRPDA, Kovilpatti centre is located in the Southern agroclimatic<br />
zone of Tamil Nadu with domain districts of Madurai,<br />
Sivagangai, Ramanathapuram, Virudhunagar, Tirunelveli,<br />
Thoothukudi and Tenkasi districts. The climate of this zone<br />
is semi-arid and the main cropping season is during northeast<br />
monsoon under rainfed conditions. Out of the total annual<br />
average rainfall of 699.1 mm in 42 rainy days, the south - west<br />
monsoon contributes 20.8% (145.2 mm) while north-east<br />
monsoon contributes 55.9% (390.6 mm) and 19.3% (134.7 mm)<br />
during summer. The onset of south west monsoon is during first<br />
week of June and north east monsoon is during third week of<br />
October. Occasionally the onset of south west monsoon may<br />
delay one or two weeks. Dry spells occur during the early<br />
season and during the middle of the cropping season. Highest<br />
maximum monthly temperature was recorded during May (38<br />
°C) and lowest maximum monthly temperature was recorded<br />
during December (30.8 °C). Highest minimum monthly<br />
temperature was recorded during June (25.1 °C) and lowest<br />
minimum monthly temperature was recorded during the month<br />
of January (19 °C).<br />

Dryland agriculture problems<br />
Soil and land management<br />
●<br />
●<br />
In this region black cotton soil occurs in nearly two-thirds<br />
and red soils occur in about one-third of the area. Soils<br />
possess high volume expansion followed by contraction,<br />
resulting in formation of cracks and loss of soil moisture.<br />
Soil cracks are formed generally during January and<br />
develop due to dry weather till receipt of summer showers<br />
in May.<br />
Soils are poor in available N and medium in P and high<br />
in K.<br />
Crop production<br />
●<br />
●<br />
●<br />
●<br />
Crops are mainly grown depending on rainfall received<br />
during North-east monsoon season.<br />
Delayed onset of monsoon, prolonged dry spells during<br />
crop growth and early cessation of rains affect the crops at<br />
different stages.<br />
Poor farm mechanization<br />
Lack of Poor crop diversification<br />
Socio-economic issues<br />
●<br />
●<br />
●<br />
●<br />
Small land holdings and fragmented lands<br />
Poor investment capacity of farmers<br />
Market risks<br />
Inadequate availability of agriculture inputs during the<br />
season<br />

Significant achievements/findings<br />
Rainwater management<br />
To understand the runoff water generation for storing in a water<br />
harvesting structure and for effective reuse, rainfall-runoff<br />
relationship was developed by measuring the runoff water, and<br />
it was found that nearly 35% of the rainfall is available as runoff<br />
and runoff causing rainfall events were 3-4. Runoff causing<br />
rainfall (mm) was 170 mm. The probability of getting 30% of<br />
rainfall as runoff is 75%. This runoff water can be harvested<br />
through in-situ and ex-situ moisture conservation practices to<br />
increase the yield of dryland crops.<br />
Adoption of tied inter-rows recorded higher average yield of<br />
623 kg/ha of seed cotton which was 10.9% higher than that of<br />
farmers’ practice. However, higher consumptive use efficiency<br />
was recorded with formation of small watersheds. Studies on<br />
suitable land treatment for soil and water conservation practices<br />
in vertisol revealed that compartmental bunding was found better<br />
for in-situ moisture conservation and achieving higher yields<br />
of cotton, sunflower, sorghum and blackgram. Compartmental<br />
bunding was superior as only 11.8% of the seasonal rainfall<br />
was lost as runoff as compared to the farmers’ practice (30%).<br />
Similarly, the reduction in runoff due to the land treatments was<br />
60, 48.3 and 27.0% due to compartmental bunding, vettiver and<br />
broad bed and furrows, respectively. For example, in semiarid<br />
vertisols, having a land slope of 1% and an annual rainfall of<br />
600-700 mm, compartmental bunding (8 m x 5m) formed across<br />
the slope helps in reducing runoff to the tune of 60% resulting<br />
in 25% yield increase in sorghum with a B:C ratio of 1.40. For<br />
yield maximization in rainfed maize, broad bed and furrows<br />
along with application of recommended dose of fertilizer + 25<br />
kg ZnSO 4<br />
/ha recorded highest grain yield of 2923 kg/ha with a<br />
B:C ratio of 1.96 and RWUE of 6.29.<br />
Cropping systems<br />
Intercropping of cotton with pulses at row ratio of 3:1 was<br />
observed to be more profitable and the yield of cotton was<br />
not affected. The performance of paired row system of cotton<br />
sowing and uniform row sowing along with 12 intercrops viz.,<br />
greengram, blackgram, cowpea (long duration - CO 1), cowpea<br />
(short duration - EC4216), lab lab, coriander, sesamum, sorghum,<br />
sunflower, safflower, bajra and foxtail millet did not affect yield<br />
and monetary return of main crop. Cotton (MCU 6) with black<br />
gram combination produced higher yield of kapas than pure crop<br />
of cotton. Intercropping of foxtail millet and coriander were also<br />
found to be ideal for cotton based intercropping system. There<br />
was extra monetary return by growing cowpea, coriander, green<br />
gram, black gram or foxtail millet as intercrop with the pure<br />
crop of the cotton. Between the two system of planting namely,<br />
wider planting (60 cm between rows) and narrow planting (45<br />
cm between rows), the narrow planting was found to be better<br />
and gave significantly higher yield.<br />
Manoharan et al.<br />
150<br />
High density planting of cotton at 45 cm x 15 cm recorded<br />
significantly higher number of bolls and kapas yield (1242 kg/<br />
ha) than 45 cm x 10 cm. Among the moisture conservation<br />
practices, broad bed & furrow system was found better than<br />
compartmental bunding. In-situ green manuring in cotton with<br />
sunnhemp and daincha produced on an average of 5 - 6 t/ha of<br />
green manure biomass, whereas the fodder cowpea yielded up to<br />
7 to 8 tonnes of green biomass. Higher yield was recorded under<br />
cotton + sunnhemp (924 kg/ha) followed by cotton + dhaincha<br />
(899 kg/ha) as compared to sole cotton (754 kg/ha).<br />
K.Tall (Tall) sorghum hybrids intercropped with different<br />
legumes viz., blackgram, lablab, cowpea and redgram, blackgram<br />
produced higher sorghum equivalent yields and net return than<br />
sole sorghum. Considering the LER and net income under<br />
sorghum based intercropping system, main crop sorghum with<br />
100% population and intercrop of cowpea with 50% population<br />
was optimum to get higher income and LER value under dryland<br />
condition. Similarly, intercropping of sorghum with pulses such<br />
as lablab and pigeonpea in both 2:1 and 4:2 row ratios was found<br />
optimum for achieving higher yields and economic returns.<br />
Intercropping of bajra with cluster bean, cowpea and pigeonpea<br />
was found better for higher yields and highest net return. Among<br />
different millet-based cropping systems, sorghum + sunflower<br />
(2:1) was found superior followed by sorghum + sunflower<br />
(4:1). Among different vegetable based intercropping systems,<br />
field lab-lab + sunflower (6:1) was found better than other<br />
intercropping systems.<br />
Nutrient management<br />
Application of 120 kg N/ha was found optimum for rainfed<br />
cotton. Among the fertilizer application methods, application of<br />
50% fertilizers as basal and 50% as top dressing increased the<br />
seed cotton yield (7.06 q/ha) followed by precision placement 5<br />
cm by side and 5 cm below seed (6.68 q/ha). Application of 20<br />
N + 60 P 2<br />
O 5<br />
kg/ha registered higher grain yield (21.01 q/ha) and<br />
followed by the treatment received 40 N + 60 P 2<br />
O 5<br />
kg/ha (20.06<br />
q/ha) and 40 N + 40 P 2<br />
O 5<br />
kg/ha (19.98 q/ha). Application of 10<br />
kg P 2<br />
O 5<br />
as DAP + 8 kg N/ha registered higher yield (8.81 q/ha)<br />
of Black gram.<br />
Hand dibbling at 45 x 15 cm weeding as and when required,<br />
spraying for complete control of pest and diseases along with<br />
the fertilizer dose of 40:20:0 NPK kg/ha for bajra (KM2)<br />
recorded higher grain and straw yield. Combined application of<br />
urea (20 kg N/ha) + FYM (20 kg N/ha) + 10 kg P/ha improved<br />
the sorghum and pearl millet grain yield by 35 and 66%, over<br />
control. The highest B:C ratio was obtained with application of<br />
20 kg N/ha as farm residue + 20 kg N/ha as urea + 10 kg P/ha.<br />
Combined application of organics along with inorganics (NPK)<br />
+ zinc sulphate of 25 kg/ha recorded 34 and 64% increase over<br />
control for sorghum and pearl millet crops, respectively over
years in semi-arid vertisols. In addition, application of organics<br />
along with inorganic (NPK) fertilizers helped to save 50% of<br />
recommended P besides enhancing crop production under<br />
dryland condition.<br />
In a long-term manurial experiment on cotton + blackgram<br />
and sorghum + cowpea rotation-based cropping systems,<br />
sustainability in yield over years was maintained by combined<br />
application of urea at 20 kg N/ha, FYM at 20 kg N/ha and SSP<br />
at 20 kg P/ha. Combination of 75% of the recommended N as<br />
urea along with enriched FYM at 750 kg/ha and soil application<br />
of Azospirillum (2 kg/ha), Phosphobacteria (2 kg/ha) is<br />
recommended for cotton and sorghum in dry land vertisols.<br />
Combined application of 50% of the recommended dose of<br />
N (20 kg N/ha) as organics (FYM / GLM) and the remaining<br />
dose N (20 kg N/ha) through urea had beneficial effect not<br />
only to improve yield of crops (cotton and sorghum) but also<br />
enhanced moisture use efficiency and maintained soil fertility<br />
in terms of organic carbon, compared to application of 100%<br />
of the recommended dose of inorganics alone. In cotton (KC<br />
3), application of recommended NPK with foliar spray of 1%<br />
MgSO 4<br />
+ 0.5% ZnSO 4<br />
+ 0.5% Borax recorded highest seed<br />
cotton yield and B:C ratio. In the vertisol tract of southern Tamil<br />
Nadu, combined application of 15 kg N/ha as compost and 20<br />
kg N/ha as inorganic fertilizer was found ideal combination for<br />
increased yield of sorghum + cowpea intercropping system.<br />
Alternate land use system<br />
A field study on agro forestry systems revealed that neem,<br />
silk cotton and tamarind are ideal tree components for agroforestry<br />
system which permit sustainable growth of agricultural<br />
crops at lower input levels. The configuration of land created<br />
by the land use system has also contributed much in soil and<br />
moisture conservation and utilization, besides, maintaining<br />
sustainable yield and income level. The average yield and<br />
higher B:C ratio were higher with tamarind plus blackgram<br />
system than other agro-forestry systems. It was observed that<br />
whenever rainfall distribution was uniform, cotton + blackgram<br />
intercropping system gave higher yield and income, whereas the<br />
B:C ratio was low due to high cost of cultivation for cotton.<br />
Under normal rainfall situation, the yield of blackgram raised<br />
under agri-silviculture and agri-horticultural systems were<br />
more. The late sown sunflower crop depends purely on late<br />
showers and residual soil moisture. Among the tree species,<br />
Ailanthus excelsa exhibited poor performance in deep vertisol<br />
as compared to tamarind. In another alternate land use system,<br />
sapota + maize registered higher system productivity followed<br />
by sapota intercropped with sorghum. The mean B:C ratio was<br />
also higher under sapota plus maize system (1.90) followed by<br />
sapota plus sorghum (1.80).<br />
Integrated farming systems<br />
The percentage contribution of agricultural component to the<br />
total gross and net income of integrated farming system was<br />
10 and 6.7% as compared to the percentage contribution of<br />
dairy component with 90 and 93.3% indicating that a dairy unit<br />
also could be included as one of a successful farming system<br />
enterprise under dryland conditions. Involving crops, goat (2<br />
+1), sheep (5+1), dairy (1 milch cow), and poultry (20 broiler<br />
birds) enterprises for an area of 1.0 ac including 0.5 ac for crop<br />
activity, fodder production and cattle shed based IFS model<br />
revealed that total gross income was higher under the IFS model<br />
having crop + goat + poultry + sheep + dairy and B: C ratio<br />
of 1.75, which was closely followed by IFS model having crop<br />
+ goat + poultry + dairy. Modified integrated farming system<br />
(crop, diary, goat) model recorded mean gross income of Rs.<br />
60644 /ha whereas cropping alone recorded Rs.16308 /ha with<br />
an additional income of Rs. 44336/ha was generated by noncrop<br />
units of the integrated farming system. The employment<br />
opportunities were also increased from 191 to 405 man-days/<br />
ha with an additional 214 man-days by the integration of crop,<br />
dairy and goat rearing in dryland vertisols of southern zone of<br />
Tamil Nadu.<br />
Energy management<br />
Performance evaluation of tractor operated air assisted seed drill<br />
for sowing minor millets indicated that, line sowing of minor<br />
millets with air assisted seed drill resulted in 30 to 40% saving<br />
in seed rate. The time taken for sowing one hectare was 1.24<br />
hours with air assisted seed drill and was three times faster<br />
than broadcasting resulting in high area of coverage which<br />
is essential under dryland conditions to make use of the soil<br />
moisture effectively. Sowing of barnyard millet, foxtail millet<br />
and little millet with air assisted seed drill also recorded higher<br />
yield. Rotovator ploughing + chisel ploughing recorded higher<br />
water use efficiency of 2.29 kg/ha-mm, 10 – 23% higher yield<br />
than conventional tillage, higher B:C ratio of 1.54 in green gram.<br />
In cotton (KC3), the rotovator ploughing + chisel ploughing<br />
recorded higher water use efficiency of 2.46 kg/ha-mm, 12%<br />
higher yield than the conventional tillage, and higher B:C ratio<br />
of 1.32.<br />

Technologies upscaled in convergence with various<br />
programmes<br />
The listed technologies have been upscaled in convergence<br />
with department of agriculture, Thoothukudi and Virudhunagar,<br />
KVKs of Thoothukudi and Virudhunagar districts and field<br />
demonstration through progressive farmers.<br />
Impact of dryland technologies<br />
Broad bed and furrow technique for in-situ moisture conservation<br />
in rainfed maize in Tamil Nadu, using ferti seed drill helped<br />
in formation of broad bed furrows (BBF), fertilizer application<br />
and sowing simultaneously saving time, labour and energy. The<br />
added advantage of the implement was that it can also be used<br />
for interculture operation. This technology helped the farmers of<br />
Thoothukudi, Tirunelveli, Virudhunagar and Tenkasi districts to<br />
take up timely sowing of maize in an area of 1.2 lakh hectares<br />
which resulted in higher yield and income. Forming ridges and<br />
furrows by using tractor drawn ridger and dibbling of seeds at 1/3 rd<br />
distance from the top of the ridge resulted in better conservation<br />
of moisture and crop growth with 10 to 15% improved yield.<br />
Adoption of ridges and furrows for sorghum resulted in 11.11%<br />
increased yield of sorghum. The cropping system coriander +<br />
chickpea + senna individually and collectively performed well.<br />
The net profit ranged from a maximum of Rs. 15,000-20,000/ha<br />
under limited moisture condition. This system helped in better<br />
farm income and improved the profit of the farmers in an area of<br />
8000 hectares in the domain districts.<br />
Farm ponds of 500 cubic metre capacity for one ha catchment<br />
area can harvest runoff water for giving supplemental irrigation<br />
to 0.4 ha. Providing one supplemental irrigation at 5 cm depth<br />
during moisture stress period resulted in an increased yield of<br />
12 to 15% in cotton. Rainwater harvesting by digging 300 ponds<br />
in each district of Thoothukudi, Tirunelveli, Virudhunagar and<br />
Tenkasi districts resulted in yield benefit of 360 tonnes and<br />
income of Rs.1.8 crores. Early sowing (immediately after the<br />
onset of monsoon) with higher seed rate of 20 kg/ha treated with<br />
imidacloprid @ 5 g/kg followed by spraying of NSKE @ 5%<br />
45 DAS and neem oil @ 3% 60DAS was recommended as IPM<br />
for sorghum through OFTs which was accepted and included<br />
in crop production guide prepared by Tamil Nadu Agricultural<br />
University, Coimbatore.<br />
Integration of intercropping system of cotton + black gram,<br />
sorghum + cowpea with animal component (goat) recorded<br />
higher system productivity (sorghum equivalent yield) of 16978<br />
kg/ha and total system income of Rs.1,16,098/ha under dryland<br />
condition. This practice has been adopted by small and marginal<br />
farmers and this technology has generated the employment<br />
opportunities for the family members which ultimately resulted<br />
in improved standard of living of dryland farmers. Foliar spray<br />
of 1.0 % magnesium sulphate + 0.5% zinc sulphate (5.0 kg of
MgSO 4<br />
+ 2.5 kg of ZnSO 4<br />
/ha in 500 litres of water) at square<br />
formation stage and boll formation stages in cotton enhanced<br />
the seed cotton yield by 3280 tonnes and income by Rs.16.5<br />
crores in Thoothukudi, Tirunelveli, Virudhunagar and Tenkasi<br />
districts.<br />
Rainwater management technologies such as ridges and<br />
furrows, compartmental bunding and tied ridging for improving<br />
crop yield are being practiced by most of the rainfed farmers.<br />
These technologies have improved yield up to 20% for rainfed<br />
crops. Farm ponds are also constructed in dryland farmers’<br />
fields by providing subsidies through Tamil Nadu Agricultural<br />
Engineering Department and World bank funded TN-Irrigated<br />
Agriculture Modernization project. Using tillage equipment<br />
like disc plough, MB plough and chisel plough ensures higher<br />
yield due to enhancement of in-situ conservation of moisture.<br />
Seed drill, one of the most popular implements for taking timely<br />
sowing is being used in dryland areas.<br />
Improved drought tolerant varieties recommended by<br />
AICRPDA centre such as sorghum - K12, cotton - KC 3, and<br />
K12, blackgram - VBN 8, VBN 11, greengram – CO7 and CO 8,<br />
maize – COH(M)6, COH(M)8, chillies – K1, K2, bajra – CO(Cu)<br />

Brief history of the centre<br />
The All India Coordinated Research Project for Dryland<br />
Agriculture Centre at Parbhani (Maharashtra, India) was<br />
established in 1977 under Vasantrao Naik Marathwada Krishi<br />
Vidyapeeth to cater to the needs of dryland farmers of the<br />
region. The domain districts the AICRPDA Centre, Parbhani<br />
are Parbhani, Nanded, Hingoli, Beed, Latur, Osmanabad,<br />
Aurangabad, and Jalna.<br />
Agro-climatic zone characteristics<br />
Marathwada region is one of the four regions of Maharashtra<br />
state with cultivable area of 5.6 M ha and 85 per cent of<br />
cultivated land is rain dependent. The region receives annual<br />
rainfall in the range of 500 to 1100 mm with assured rainfall<br />
zone (60%), moderately high rainfall zone (20%) and scarcity<br />
zone (20%). Agro-climatically, the region is divided into three<br />
zones. The Central Maharashtra plateau zone is the biggest one<br />
with assured rainfall pattern with parts of Aurangabad, Beed,<br />
Jalna, Osmanabad, Latur, Nanded, Hingoli & Parbhani. Towards<br />
the western end, the parts of Aurangabad, Beed & Osmanabad<br />
come under the scarcity; whereas the north eastern part of the<br />
region, i.e., Hingoli & Nanded has moderately high rainfall. The<br />

Significant achievements<br />
●<br />
●<br />
Farm pond sizes have been standardized for the Marathwada<br />
region<br />
A suitable open well recharge system was developed.<br />
Working principle: The improved open well recharge<br />
technology comprises a model filtration unit for the<br />
artificial recharging of open wells. The designed model<br />
consists of three blocks viz., the primary filter unit, an<br />
energy dissipation structure, and the main filter unit. Runoff<br />
water is diverted towards the well recharge unit through<br />
field trenches. Then it allows it to enter in primary filter<br />
unit wherein the major sediments are arrested and water<br />
flows to the secondary filter unit where the velocity of the<br />
running water slows down and then water enters the main<br />
filtration unit. The runoff water gets filtered in the threestage<br />
filter and passed to the open well which is connected<br />
to the filtration unit by a 4” dia. PVC pipe at 2 m below<br />
the soil layer. The artificial well recharging resulted in an<br />
increase in water level to the tune of 0.5 m to up to 3.4 m<br />
over a period of 3 years.<br />

Borewell recharge system was developed. Considering<br />
the specific gravity of silt in runoff water and using the<br />
principle of Stroke’s law, the filtration unit was designed.<br />
The filtration unit consists of the excavation of a circular<br />
pit of diameter 1.5 m and a depth of 2 m. From the bottom,<br />
up to 50 cm above, small holes are drilled into the casing<br />
pipe of the borewell and then wrapped with nylon mesh in<br />
a double layer followed by filling of stones up to 50 cm<br />
height, the second layer above the first layer consists of a<br />
filling of metal (small stones) and then the overlaid by a<br />
horizontal nylon mesh. The third layer consists of a 30 cm<br />
height of gravel followed by a 20 cm layer of fine sand.<br />
The filtration efficiency was worked out by comparing<br />
the inlet and outlet silt compositions in the water. The pre<br />
and post-monsoon water levels in some of the recharged<br />
and un-recharged borewells were monitored using digital<br />
water level indicators. The water level fluctuations were<br />
worked out. The aquifer characteristic like specific gravity<br />
and transmissivity were determined by conducting longduration<br />
pumping tests on some of the borewells. Thus, the<br />
groundwater recharge was estimated using specific yield<br />
and water level fluctuation data.The filtration efficiency<br />
was found to be 64 to 67 %. The groundwater level has<br />
been increased from 2.13 to 4.84 m. The ground water<br />
recharge in treated borewells was found to be 13.65 percent<br />
of annual rainfall as against 3.92% in untreated borewells.<br />
Artificial well recharging is found effective for groundwater<br />
enhancement.<br />
Opening of conservation furrow after every 4 rows in sole<br />
soybean and soybean + pigeonpea (4:2) intercropping (sown<br />
at 45 cm row distance) after 30 to 35 days of sowing was<br />
adopted as a strategy for moisture conservation on farmers<br />
field during last decade. The conservation furrow has<br />
opened using either bullock or tractor-drawn iron plough<br />
or ridger. The farmers are using their own plough after the<br />
first weeding operation in soybean. The cost of ridger is<br />
Rs.2200/- and the operational cost is found to be Rs. 800 to<br />
Rs. 1000 per hectare.<br />
Sowing of soybean was developed with standard row ratios.<br />
The tractor drawn BBF planter was effectively used for<br />
soybean sowing at 45 cm row spacing so that 4 rows on<br />
soybean are on bed and furrow was opened on both sides<br />
which helps for moisture conservation and furrows also act<br />
as drainage channels in extreme rainfall events for removing<br />
excess rainwater so that crop is not under waterlogged<br />
condition. In assured rainfall area of Marathwada region,<br />
BBF system of sowing soybean proved viable. When rainfall<br />
is less, all water conserved in furrows and crop was free<br />
from moisture stress condition and during excess rainfall<br />
event, the excess runoff water was drained through furrow<br />
and crop was free from waterlogged situation particularly in
●<br />
●<br />
medium to deep black soils of the regions. The crop yields<br />
under BBF are 20 to 25% higher in soybean. Similarly<br />
this BBF technology reduces runoff and soil loss by 20%.<br />
BBF system improves soil physical condition, enhances<br />
root development and water use efficiency and performed<br />
better during dry spell at pod filling and seed developing<br />
condition.<br />
Application of two sprays of 19:19:19 @ 0.5 % at 35 days<br />
and at 75 days after sowing, respectively or potassium<br />
nitrate (KNO 3<br />
) at 35 days (@ 1.0%) and at 75 days after<br />
sowing (@ 2.0%) respectively along with a recommended<br />
dose of fertilizers (120:60:60 NPK kg/ha) in medium to<br />
deep black soils was found significantly superior for dry<br />
spell management in Bt cotton.<br />
In soybean within 40 days after sowings to mitigate dry<br />
spells, an additional two to three hoeing are to be taken<br />
up in addition to normal hoeings with the help of bullockdrawn<br />
hoe. This is to create dust mulch. Further, mulching<br />
can be done with locally available crop residues (within<br />
two weeks after sowing) and also foliar spray is done with<br />
kaolin (6%). The above similar practice can be adopted<br />
in cotton within 75-80 days after sowing to mitigate dry<br />
spells however with an additional four to five hoeing with<br />
the help of bullock drawn harrow. The cost of operations<br />
is Rs. 3000/- ha. These practices help in a yield increase<br />
up to 15% in soybean and 23% in cotton compared to no<br />
mitigation practices.<br />

Brief history of the centre<br />
ICAR-IISWC Research centre, Ballari was established in 1954<br />
by Government of India to conduct research on problems related<br />
to soil and rainwater conservation on medium to deep black soils<br />
of low rainfall region. The All India Coordinated Research Project<br />
for Dryland Agriculture Centre was established in 1970-71 at<br />
Regional Station, Ballari, Central Soil and Water Conservation<br />
and Training Centre (now, Indian Institute of Soil and Water<br />
Conservation) and continued up to 1986. Later, the Centre was<br />
continued as voluntary Centre from 1998 till 2008. Again in<br />
2018, the Centre was made voluntary Centre in AICRPDA. The<br />
domain districts of the Centre are Ballari, Chitradurga, Raichur,<br />
Koppal, Gadag, Bagalakote, Yadgir, Kalaburgi and Vijayapura<br />
districts of Karnataka.<br />
Agro-climatic zone characteristics<br />
The Centre is located in the Northern Dry Agro-Climatic Zone<br />
(Zone-3) of Karnataka, which is divided into five agro-ecological<br />
sub regions (ESR), viz., Hot arid ecological sub-region (coded<br />
as 3), Hot dry semi-arid ESR (6.1), Hot moist semi-arid ESR<br />
(6.2), Hot dry sub-humid ESR (6.4) and Hot dry semi-arid ESR<br />
(7.1). The zone covers 56 taluks of northern Karnataka and<br />
large part of the zone area (2.42 million ha, ~50%) is under hot<br />
arid ESR. The Ballari Centre in the semi-arid tropics of South<br />
India is located in rain shadow belt with an average rainfall of<br />
520.2 mm year -1 occurring in average 32 rainy days. Probability<br />
analysis of weekly rainfall suggests assured rainfall between<br />
standard meteorological weeks of <strong>37</strong> and 44, which corresponds<br />
to the period of September 10 to November 4. This period is<br />
considered safe for cropping in deep and very deep black soils of<br />
the tract. The sixty-five years of rainfall recorded in the Centre<br />
show five years of large-excess rainfall, 16 years of excess<br />
rainfall, 29 years of normal rainfall, 14 years of deficient rainfall<br />
and one year of large-deficient rainfall, over the average annual<br />
rainfall. Both excess and deficient rainfall situation hamper the<br />
crop production in the region.<br />
Soils of the region<br />
The soils are classified as ‘Vertisols’ and fall under the sub<br />
orders of ‘usterts’ and ‘pellusterts’ and sporadic ‘aquerts’. Deep<br />
Vertisols in Ballari region possess ESP of 7.0 or more in case<br />
of swelling soils, which is detrimental to crop growth due to<br />
poor soil physical conditions. The moisture retained at 1/3 and<br />
15 bar suction pressure varies from 36 to 50% and 22 to 25%,<br />
respectively. The maximum water holding capacity of these<br />
soils varies from 60 to 65% and bulk density from 1.2 to 1.3<br />
Mg m -3 . Clay content varies from 32 to 55% and increases with<br />
depth. The clay minerals are of montmorillonite and beidellite<br />
group with cation exchange capacity (CEC) of 100 cmol (p+)<br />
kg -1 of clay. Exchangeable sodium percentage varies from<br />
3 to 21% and pH increases with depth (8.0 to 9.2). Soils are<br />
well supplied with bases and are poor in humus and extremely<br />
deficient in available N and P. Soils are marginal with respect to<br />
iron and zinc and deficiency of these micro-nutrients is higher<br />
under intensive management/crop cultivation. The major rainfed<br />
crops cultivated in the region during kharif-rabi seasons are<br />
greengram, cowpea, cotton, redgram, sunflower, chickpea, rabi<br />
sorghum, safflower and coriander.<br />
Significant achievements<br />
Production agronomy<br />
Under production agronomy, the Centre has evaluated optimum<br />
sowing time of crops for the back-soil region and also conducted<br />
evaluation of hybrids and varieties of various crops, viz.,<br />
sorghum, safflower, chickpea and redgram (Table 1, 2). Further,<br />
plant population studies of the various crops were conducted to<br />
adjust plant density according moisture availability in the soil<br />
as a drought mitigation strategy. Crops and production practices<br />
were evaluated against the prevailing weather conditions in<br />
the regions. Best suited crops and associated best production<br />
practices were identified (Table 3). A multitude of crops have<br />
been screened at different dates of planting to identify crops<br />
suited for different contingencies of weather outlined elsewhere<br />
(Anonymous, 1980).<br />

Mid-seasonal corrections<br />

(Anonymous, 1980).<br />
Whenever profile moisture at sowing<br />
time is low due to either failure of kharif<br />
rains or its erratic distribution or both<br />
Rabi sorghum: removing the alternate<br />
plant, third plant or third row resulted in<br />
a significant <strong>37</strong>% yield increase in rabi<br />
sorghum. Plant population reduction and<br />
supplemental irrigation (4 cm depth)<br />
resulted increased in sorghum grain and<br />
straw yields, respectively<br />
Safflower: varied response to population<br />
correction commands for recommended<br />
seed rate<br />
Intercropping of rabi sorghum under different cropping systems<br />
in rainfed Vertisols: Traditionally rabi sorghum is sown along<br />
with either pulses or oilseeds as a mixed crop in the region.<br />
Intercropping on a population replacement basis offers scope for<br />
enhancing the crop yields, besides acting as insurance against<br />
the total failure of either crop. A study conducted (1981–82<br />
to 1984–85) with sorghum (CSV–8R) as the main crop and<br />
coriander (local), field bean (CO–7), safflower (A–1) and<br />
chickpea (A–1) as intercrops in ratios of 1:0, 1:1, 2:1, 3:1 and<br />
0:1 to find out a suitable crop and its ratio, revealed that during<br />
the above normal rainfall years, significantly higher sorghum<br />
grain equivalent yields (SGEY) was recorded under sorghum<br />
+ field beans intercropping (4404 kg ha -1 in 1981–82 and 3965<br />
kg ha -1 in 1983-84), whereas during normal year (1982–83)<br />
sorghum+coriander (2714 kg ha -1 ) and below normal years<br />
(1984–85) sorghum+safflower (1268 kg ha –1 ) performed better.<br />
The sole crop of fieldbeans recorded a higher average SGEY<br />
(2798 kg ha -1 ) and a lower SGEY was recorded in coriander (930<br />
kg ha -1 ). During the below-normal rainfall year (1984–85), when<br />
other intercrops as well as sole crops failed, chickpea recorded<br />
higher SGEY (1343 kg ha -1 ). Therefore, during good rainfall<br />
years it was recommended to cultivate sorghum intercropped<br />
with field beans when crops are sown in the first/second fortnight<br />
of September, whereas, during low rainfall years when sowing<br />
gets delayed beyond September, sorghum is to be intercropped<br />
with chickpea for higher profitability. Among the ratios, 3:1<br />
(sorghum+chickpea) was beneficial for the region. Of late, due<br />
to shift in the rainfall from September (120 mm) to October (140<br />
mm), chickpea alone or chickpea mixed crop with rabi sorghum<br />
162
has become more popular by replacing rabi sorghum and<br />
sunflower due to labour problem for harvesting of sorghum and<br />
non-availability of high yielding sunflower cultivars. It has been<br />
advised to have crop rotation of winter sorghum with chickpea<br />
during normal to above normal rainfall situations for sustaining<br />
soil properties with higher crop yields and returns in the region.<br />
Conservation agronomy<br />
Soil and moisture conservation practices: Soil and rainwater<br />
conservation measures are required in deep black soils of<br />
Northern Dry Zone of Karnataka, adjacent Kurnool and<br />
Anantapur districts of Andhra Pradesh, Kovilpatti region of<br />
Tamil Nadu, and parts of Southern Maharashtra which are left<br />
fallow during the south-west monsoon period, to reduce soil and<br />
nutrient losses. Several agronomic and cultural practices have<br />
also been evaluated at the Centre for identifying effective soil<br />
and rainwater conservation (SWC) measures within the bunded<br />
area (inter-terrace level).<br />
Establishment of vegetative cover in kharif season: Cereals,<br />
legumes, and oilseeds/grasses were evaluated for their<br />
suitability, either as cover, grain and/or fodder crops or both<br />
over a decade during 1960’s. Performance of legumes, i.e.,<br />
greengram, cowpea, blackgram, Dolichos, soybean and<br />
clusterbean were poor due to insufficient rains with droughts<br />
of different magnitudes. Cultivation of groundnut was found<br />
highly risky and non-remunerative in addition to crop harvesting<br />
problems in the absence of rains. Therefore, the kharif cropping<br />
on deep black soils of the Ballari region is not much favourable.<br />
Performance of vegetative barriers: A five years (1989–93)<br />
evaluation of vegetative barriers effectiveness showed 19 and<br />
36% lower winter sorghum grain yields in the khus/lemon grass<br />
and Leucaena vegetative barriers when compared to 798 kg ha -1<br />
under control. This indicates the non-suitability of vegetative<br />
barriers as a soil and rainwater conservation practices in the<br />
Ballari region.<br />
Contour strip cropping: Feasibility of contour strip cropping<br />
to reduce soil erosion and increase productivity was evaluated<br />
with erosion permitting (sorghum and cotton) and resistant<br />
(groundnut) crops in 2:1, 3:1 and 4:1 ratio with a view to<br />
determine optimum strip ratio. Results indicated that varying<br />
proportions of groundnut least affected yields of winter crops.<br />
Hence, contour strip cropping was not effective due to poor<br />
establishment of monsoon crops in the black soils of Ballari<br />
region.<br />
Contour cultivation: Cultivation of crops along the slope leads<br />
to losses in fertile top soil, nutrients, and rainwater and does not<br />
wet the soil profile and results in lower crop yields. Cultivation<br />
of crops on contours in the farmer’s fields for three consecutive<br />
below-normal rainfall seasons in and around Ballari in deep<br />
black soils showed an increase in grain yield by 22% in Setaria<br />
163<br />
and 35% in rabi sorghum over up and down cultivation.<br />
In-situ rainwater conservation practices: Land treatments like<br />
ridge furrows, listing and corrugations alone or with gypsum<br />
application registered non-significant increase in sorghum and<br />
cotton yields. The magnitude of increase in sorghum yield<br />
was 120% (1230 to 2700 kg ha -1 ) during normal rainfall year<br />
compared to above normal rainfall years 35% (2130 to 2870<br />
kg ha -1 ) with organic trench ridging over control. The interterrace<br />
bedding system (narrow beds on grade would help to<br />
drain out the stagnant water during excess rainfall situations and<br />
conserve every drop of rainwater in-situ during low rainfall)<br />
was beneficial and increased winter sorghum yields by 24% (8<br />
years average) and safflower yields by up to 8% (Average of 7<br />
years) over flatbed sowing. Compartmental bunding (CB) and<br />
ridges and furrows (R&F) conserved fertile top soil, rainwater<br />
in-situ and increased the soil water, nutrients in the profile, and<br />
produced higher grain yield by 28% with CB and up to 36%<br />
with R&F in winter sorghum during the moderate drought year<br />
(2000–01). During severe drought year (2002–03), the grain<br />
yield increased by 16% with CB and 20% in R&F with water<br />
stress at reproductive stages of crop growth. During abovenormal<br />
rainfall year (2001-02) the grain yield was higher by<br />
13 and 16% with CB and R&F, respectively. The mean grain<br />
yield (average of 3 years) increased by 17% (2122 kg ha -1 ) &<br />
22% (2206 kg ha -1 ) with CB and R&F, respectively over flat-bed<br />
(1815 kg ha –1 ). The water use efficiency in CB increased by 13%<br />
(8.26 kg ha -1 mm -1 ) and 16% with R&F (8.48 kg ha -1 mm -1 ) over<br />
flatbed sowing (7.34 kg ha -1 mm -1 ) indicating importance of insitu<br />
rainwater conservation practices in Ballari region.<br />
Tillage practices to reduce evaporation and weeds control:<br />
Organic surface cover reduces evaporation, soil loss and<br />
conserves rainwater in-situ. Even dust mulching reduces<br />
evaporation from soil surface due to reduced surface cracking<br />
at later stages of crop growth. Studies on surface mulching<br />
indicated higher rabi sorghum grain and straw yields by 88%<br />
and 21%, respectively while clod mulch (10 cm deep) recorded<br />
8% higher grain yield of 1833 kg ha -1 over surface mulch<br />
(Average of 5 years during 1980s). In black soils of Ballari,<br />
surface (organic) mulch was highly beneficial. In its absence,<br />
dust mulching (5 to 10 cm) during cropping season conserves<br />
rainwater and increases crop yields. Across four seasons (1978-<br />
79 to 1981-82), weed control by hand khurpi increased yield by<br />
112% over control. Inter-culturing with blade harrow and sweeps<br />
increased sorghum yields by 41% and 32%, respectively over<br />
control. Further, yields increased by 85% and 96%, respectively<br />
when intra-row weeding was done with khurpi. Hence, interculturing<br />
with sweeps along with intra-row hand weeding is<br />
recommended due to low operational cost.<br />
Low tillage farming strategies for resource conservation and<br />
productivity: Conventional tiilage (CT) with recommended
ate of fertilizer (RRF) and hand weeding (HW) (1694 kg ha -1<br />
and 5.89 kg ha -1 mm -1 ) and low tillage (LT) with application<br />
of 2 t ha -1 of Leucaena and HW (1528 kg ha -1 and 5.65 kg ha -1<br />
mm -1 ) recorded significantly higher winter sorghum grain yields<br />
of 83% and 66% and WUE by 48 and 42%, respectively over<br />
LT with herbicide application (930 kg ha -1 and 3.98 kg ha -1<br />
mm -1 ). Hence, resourceful farmers can adopt CT and resource<br />
poor farmers can adopt LT with Leucaena application and weed<br />
control through HW in Ballari Vertisols.<br />
Tillage practices and integrated nutrient management<br />
(INM): During severe drought year (2002–03), when the crop<br />
experienced water stress at reproductive stages, there was no<br />
significant effect of tillage practices on rabi sorghum yields<br />
whereas CT (1 ploughing + 2 harrowing + 2 hoeing + 1 hand<br />
weeding) performed better with significantly greater grain yield<br />
by 15% (1876 kg ha -1 ) over low tillage treatments, i.e., RT (1621<br />
kg ha -1 ) (2 harrowings + 1 hoeing + 1 hand weeding) and 20%<br />
over LT (1561 kg ha -1 ) (1 harrowing + 1 hoeing + weedicide)<br />
during moderate drought year (2000–01) with pre-monsoon<br />
rainfall of 139.6 mm prior to sowing and 90.3 mm crop season<br />
rainfall. Higher grain yield (1791kg ha -1 ) was observed when<br />
50% N was supplied through an organic source and 50% through<br />
an inorganic source during a moderate drought (2000–01).<br />
During above normal rainfall year (2001–02) with sufficient<br />
rainfall (prior to sowing and during crop season), application<br />
of fertilizer through urea alone (inorganic source) recorded<br />
significantly higher grain yield (3064 kg ha –1 ). The mean WUE<br />
was slightly higher in CT (8.98 kg ha -1 mm -1 ) ,<br />
over RT (8.73<br />
kg ha -1 mm -1 ) and LT (8.48 kg ha -1 mm -1 ). Higher sorghum<br />
grain yield (1745 kg ha -1 ) was obtained when N was supplied<br />
through organic sources alone during 2002–03 when there was<br />
a severe drought with only 9.3 mm of crop season rainfall. The<br />
results indicated that sorghum responded to a higher rate of N<br />
application whenever there was sufficient water available in the<br />
profile and whenever there was a scarcity of water in the profile<br />
during the cropping season sorghum responded to the lower rates<br />
of N application . The mean sorghum grain yield (average of 3<br />
years) increased by 9% (2063 kg ha -1 ) and 12% (2120 kg ha -1 )<br />
with 50:50 organic:inorganic and inorganic alone, respectively<br />
over 100% organic source (1892 kg ha -1 ). The WUE was 11%<br />
and 18% higher in organic and inorganic source and inorganic<br />
alone as compared to 100% organic sources.<br />
Under varying rainfall situations, CT conserved more rainfall and<br />
performed relatively better than RT or LT. Sorghum response to<br />
INM varied differently under different rainfall situations in all<br />
4 years of study. In a drought year, 50% reduced N application<br />
serves better whereas in a nearly drought year RRN is better. In<br />
a good rainfall year, 150% RRN produced a significantly greater<br />
yield . In sunflower, reduction in soil bulk density, increase in<br />
infiltration rate and porosity with higher soil water storage under<br />
Patil and Ramesha<br />
164<br />
CT compared to RT and LT was observed. Sunflower seed<br />
yields were 13% and 32% higher in CT compared to RT and<br />
LT, respectively. In INM treatments, higher rates of fertilizer<br />
application recorded higher soil moisture, decreased bulk<br />
density, and increased porosity and infiltration rate compared<br />
to INM 2<br />
and INM 1<br />
. Higher soil moisture with greater nutrient<br />
availability produced 8% and 17% higher seed yield with<br />
INM 2<br />
(100% RDN-100% urea) and INM 3<br />
(150% RDN-150%<br />
urea) compared to INM 1<br />
(50% RDN-50% urea). Thus, CT with<br />
INM 3<br />
is recommended for adoption for sustaining sunflower<br />
productivity under rainfed conditions during the winter season<br />
as a climate-resilient agricultural practice in vertisols of SAT<br />
region.<br />
Nutrient management<br />
A study was conducted at research farm and on farmers’ fields<br />
to determine the effect of N rate and sources on sorghum growth<br />
and yield during rabi season in the Vertisols of Ballari region.<br />
During normal and above-normal rainfall years, an increase in N<br />
application up to 40 kg ha -1 increased grain yield from 2128 kg<br />
ha -1 (control) to 2396 kg ha -1 . Further increase in N application<br />
was not beneficial at research farm. During the years of low<br />
rainfall, significantly higher grain yield was recorded with 20<br />
kg N ha -1 over control and was on par with 40 and 60 kg N ha -1 .<br />
Response to added N fertilizer was low in the farmers’ fields as<br />
compared to research farm and it was attributed to lower soil<br />
nutrient status for available N, P 2<br />
O 5,<br />
and K 2<br />
O. During normal to<br />
above normal years of rainfall, an increase in N application up<br />
to 60 kg ha -1 resulted in increased grain yields from 1613 kg ha -1<br />
(control) to 1785 kg ha -1 in the farmers’ field. During normal and<br />
below-normal rainfall years, application of calcium ammonium<br />
nitrate recorded higher grain and straw yields at both research<br />
farm and in farmers’ fields. Application of 38 kg N ha -1 recorded<br />
a B:C ratio of 2.67:1 during normal rainfall years and optimum<br />
rate was 33 kg N ha -1 with a B:C ratio of Rs.1.29:1 during below<br />
normal rainfall years at the research farm. In farmers’ fields,<br />
the relationship was linear with the increase in N rate during<br />
normal rainfall years and quadratic during below rainfall years.<br />
Optimum rate of 27 kg N ha -1 with a greater B:C ratio of 2.15<br />
was observed during below-normal rainfall years.<br />
Significantly higher grain yield 2629 kg ha -1 was recorded with<br />
application of 90 kg P 2<br />
O 5<br />
ha -1 with similar trend in straw yield<br />
also at research farm during normal rainfall years. Increased<br />
application of P 2<br />
O 5<br />
had no significant influence on the grain and<br />
straw yield of sorghum. However, higher grain (964 kg ha -1 )<br />
and straw yield (17.6 q ha -1 ) was recorded with application of<br />
30 kg P 2<br />
O 5<br />
during sub–normal rainfall years at research farm.<br />
Grain and straw yields of sorghum in farmers’ fields increased<br />
with increased application of P 2<br />
O 5<br />
during normal rainfall years.<br />
Higher grain yield (1848 kg ha -1 ) was recorded with application<br />
of 90 kg and straw yield with 60 kg P 2<br />
O 5<br />
ha -1 (27.5 q ha -1 ). Among
the sources, DAP application proved more beneficial than SSP,<br />
irrespective of rainfall at research farm and in farmers’ fields.<br />
During years of normal rainfall, higher grain and straw yields<br />
were recorded with DAP application, whereas, during sub–<br />
normal rainfall years yield differences due to P sources were not<br />
significant at research farm and farmers’ fields. During years<br />
of normal rainfall, 53 kg P 2<br />
O 5<br />
ha -1 produced higher B:C ratio of<br />
1.77 whereas, during sub–normal rainfall years application of<br />
26 kg P 2<br />
O 5<br />
ha -1 resulted in a B:C ratio of 1.17 at research farm.<br />
In farmers’ fields, application of 53 kg P 2<br />
O 5<br />
ha -1 was optimum<br />
during normal rainfall years and 26 kg ha -1 was optimum with<br />
greater B:C ratio of 2.14 during sub–normal rainfall years.<br />
Effect of integrated nutrient management (INM) in winter<br />
sorghum and crop rotation with chickpea either over the years<br />
or in strips over 8 years of the study indicated that the response<br />
to different INM treatments was higher in winter sorghum,<br />
followed by chickpea and sorghum + chickpea in strips. The<br />
average (8 years) winter sorghum yield response indicated that<br />
the treatment with 15 kg N through Leucaena loppings+20 kg<br />
N through urea (T 8<br />
) produced higher sorghum grain equivalent<br />
(SGE) by 56% over control followed by 51% increase in SGE<br />
with application of 100% recommended rate of N through<br />
urea (T 2<br />
). In the years of drought, application of N through 15<br />
kg N through compost +10 kg N through Leucaena loppings<br />
(T 9<br />
) increased the sorghum grain and straw yields over other<br />
treatments, whereas in the normal and above normal rainfall<br />
years application of N either with 15 kg N through Leucaena<br />
loppings + 20 kg N through urea (T 8<br />
; 100% RRN through urea)<br />
(T 2<br />
) proved better.<br />
In the chickpea block, treatment T 8<br />
produced 62% higher SGE<br />
over control followed by 53% increase in SGE with application<br />
N through 15 kg N through compost+10 kg N through Leucaena<br />
loppings (T 9<br />
). In the years of normal and above normal rainfall<br />
chickpea yields were higher when sorghum was applied with 15<br />
kg N through Leucaena loppings+20 kg N through urea whereas<br />
during drought years chickpea yields were higher when sorghum<br />
was supplemented with organic amendments through compost/<br />
Leucaena loppings in previous season. In sorghum+chickpea in<br />
strips, the treatment T 8<br />
produced 44% higher SGE over control<br />
followed by 38% increase in SGE with application N through 15<br />
kg N through compost+10 kg N through Leucaena loppings (T 9<br />
)<br />
when sorghum and chickpea were cultivated in strips and yields<br />
of sorghum and chickpea were converted into SGE.<br />
Terrace-level resource conservation measures: Graded bunds<br />
of 0.6 m 2 cross-section at vertical intervals ranging from 0.75 to<br />
1.25 m were demonstrated at the G.R. Halli watershed during<br />
1980-1994, the Chinnatekur watershed in Kurnool district<br />
during 1986-1994, and Joladarasi watershed in Ballari district<br />
during 1987-1994 for resource conservation and to improve crop<br />
yields. At Chinnatekur, the runoff from arable areas got reduced<br />
165<br />
to around 5% when compared to 9% under control with 70%<br />
reduction in soil loss. Across seasons and years, graded bunding<br />
increased yields ranging from 13 to 21% in different crops. In<br />
an evaluation of farmers’ perception, 82% of the respondents<br />
expressed problems with contour bunding as they breach and<br />
cause water stagnation and loss of area, while in case of graded<br />
bunds 66% of the farmers expressed lack of awareness as well<br />
as non-availability of technical guidance, while 6% expressed<br />
lack of conviction.<br />
Inter-terrace level resource conservation measures:<br />
Terrace level measures could not conserve rainwater, as the<br />
lands are slopy with undulations resulting in un-uniform soil<br />
wetting in farmers fields. Thus for uniform soil wetting and<br />
to break the slope and reduce velocity of runoff and increase<br />
opportunity time for rainwater to soak into the soil profile, the<br />
in-situ rainwater conservation practices like land smoothening,<br />
contour cultivation, compartmental bunding, contour borders,<br />
ridges & furrows and dead furrows were demonstrated on<br />
the farmers’ fields across seasons and locations. Adopting insitu<br />
rainwater conservation measures reflected in increase<br />
in crop yields ranging from 7.7 to 114%. Contour cultivation<br />
improved sorghum yields by 14% over control. Adoption<br />
of compartmental bunding resulted in 20 to 25% increase in<br />
groundnut and sorghum yields. Similarly, land smoothing in<br />
the inter-terraced area brought about 16% increases in yield.<br />
Developing the land into border strips brought additional yields<br />
of 19 to 114% in sorghum depending on seasonal conditions<br />
and 22% in groundnut. Vertical mulches brought an additional<br />
grain yield of 41% depending upon the location and seasonal<br />
conditions. The above measures are complementary to each<br />
other and were found to be cost-effective, with a payback period<br />
of 1 to 2 years except border strips which required 5 to 7 years<br />
depending upon the value of the produce.<br />
Land use planning<br />
The performance of crops, many a time is poor due to limitations<br />
of slope, depth, salinity, etc. Soils in the semi-arid region<br />
vary considerably with respect to their physical and chemical<br />
characteristics in a catena. The demonstrations of suitability of<br />
crops for different depths in red soils of farmers at G.R. Halli<br />
watershed indicated that even under irrigation conditions at<br />
given level of input use, the sorghum yields were higher by 46%<br />
when the soil depth increased from 22.5 cm 45 cm and above.<br />
Under similar rainfall conditions, sorghum yields were 71%<br />
higher whereas ragi yields increased by 10% with increase in<br />
soil depth from
ings about economic stability. The class V to class VIII lands<br />
not fit for agriculture account for 11 to 51% land area across<br />
watersheds located in the SAT region. Alternative land use was<br />
demonstrated on fields of ten of class VI lands at G.R. Halli<br />
watershed, Karnataka. Since the area was unfit for cultivation,<br />
the land was bunded to prevent erosion, a few farmers were<br />
permitted to grow crops and the remaining were made to grow<br />
woodlots with Eucalyptus trees. At the end of 5 years, the<br />
B:C ratio for the woodlots was 3.67 while it was only 2.93<br />
for crops. In another case at Chinnatekur watershed, Kurnool<br />
district, Andhra Pradesh, by protecting such lands from biotic<br />
interference, the grass yields improved from 2.6 to 11.6 t ha -1 .<br />
With application of 20 kg DAP ha -1 the yields increased to 17.7<br />
t ha -1 . Further, with introduction of legumes like Stylosanthes<br />
hamata, the yields increased further to 27.3 t ha -1 .<br />
In marginal lands, having the facility of protective irrigation,<br />
shifting to agri-horti system in Vertisols of Joladarasi, Ballari<br />
district, Karnataka, yielded 6 times more net returns with 3<br />
to 4 times more employment on a continuous basis compared<br />
to cultivation of sorghum with protective irrigation. In sandy<br />
river beds with trees planting at Chinnatekur watershed, A.P,<br />
the productivity was 10 t ha -1 yr -1 after 10 years of plantation.<br />
However, when this land was cultivated with jasmine/guava, net<br />
returns per hectare stabilized at Rs. 24,863 for jasmine and Rs.<br />
22,320 for guava. It is clear that land use planning according to<br />
capability and use of alternatives is required for realizing higher<br />
production capabilities.<br />
Intercropping of coriander+safflower recorded 97% more net<br />
returns compared to mixed cropping of coriander and safflower<br />
in black soils of Joladarasi watershed. Setaria + redgram<br />
cropping system recorded 61% additional net returns over setaria<br />
in Vertisols and groundnut + redgram in red soils recorded<br />
10% more net returns compared to pure crop of groundnut of<br />
Chinnatekur watershed.<br />
Among the cereal crops, kharif sorghum, ragi, bajra and setaria<br />
in red and medium black soils and rabi sorghum were evaluated.<br />
Kharif sorghum, across seasons, recorded nearly two-fold higher<br />
grain yields under improved practice when compared to farmers’<br />
practice at G.R. Halli, Hadagali and Chinnatekur watershed. The<br />
demonstrations on improved method of cultivation in oilseeds<br />
such as groundnut, safflower, sunflower and castor revealed<br />
production increases of 29, 182, 55 and 155%, respectively<br />
over farmers’ practices. In the improved technology of pulses<br />
demonstrations, chickpea recorded on an average, across<br />
seasons 451 kg ha -1 as against 190 kg ha -1 under farmers’<br />
Patil and Ramesha<br />
practice at Hadagali and 1020 kg ha -1 at Chinnatekur watershed<br />
due to favorable seasonal conditions. Redgram registered yield<br />
increases to the tune of 418 kg ha -1 as against 298 kg ha -1 under<br />
farmers’ practice at Chinnatekur watershed.<br />
Risk minimization<br />
Dryland agriculture in SAT black soil region experiences 5<br />
droughts of different intensities in a normal decade. Rainfed<br />
rabi cropping success depends upon the moisture stored in<br />
the soil profile at sowing in September and on the receipt of<br />
October rains. Hence, harvesting excess runoff and recycling<br />
as a protective irrigation enhanced 30-85% crop yields and net<br />
returns from 33% to 125% in the region. Based on advance<br />
prediction of October rains (good or bad) contingent plans to<br />
make correction in crops grown on recommended practices were<br />
developed by introducing population corrections in the standing<br />
crop to reduce risks and stabilize yields. Compartmental<br />
bunding (CB) with cultivation of BGD 103 and JG 11 chickpea<br />
varieties in Vertisols at Ballari, increased the grain yields from<br />
13 to 16%, respectively. Similarly, demonstration cum field<br />
evaluation of chickpea variety JG 11 in Joladarasi, K. Veerapur<br />
and Chellagurki villages of Ballari district indicated that higher<br />
chickpea yields, profit and energy gains can be achieved by<br />
cultivating JG 11 variety with micronutrients application at 5 kg<br />
ha -1 in Vertisols of Ballari region during winter season.<br />
Way Forward<br />
According to the prevailing farming situations, climatic regimes<br />
and biophysical endowments of the farming community in the<br />
region, the Ballari Centre has conducted need-based research to<br />
address the issues related to the production agronomy, in-situ<br />
and ex-situ soil and water conservation measures and varietal<br />
trials with varied crop combinations. The Centre has developed<br />
and promoted various in situ moisture conservation techniques,<br />
tillage practices, crops, and varieties along with integrated<br />
nutrient management for sustainable agricultural production in<br />
the domain region. Evaluated and proven dryland technologies<br />
were demonstrated in various watershed developmental projects<br />
in the region. The contemporary knowledge of the climatic<br />
situation and their predictability and improved and efficient<br />
water application techniques are prompting the Centre to<br />
continue its collaboration with AICRPDA for the evaluation of<br />
future technologies to meet the demands of unforeseen climatic<br />
situations and national targets such as doubling the farmers’<br />
income in the dryland regions through the dissemination of costeffective<br />
technologies in crop production.<br />
