Ovo istraivanje je obavljeno tokom tri godine u dva poljska ogleda, u uslovima sa i bez<br />
navodnjavanja. Ispitivano je osam hibrida kukuruza koji pripadaju razlièitim FAO<br />
grupama zrenja. Cilj istraivanja bio je utvrðivanje razlike u duini vegetacije u<br />
razlièitim uslovima gajenja i u hemijskom sastavu zrna kukuruza.<br />
Najveæe promene u hemijskom sasatavu zrna, u zavisnosti od grupe zrenja i<br />
navodnjavanja, utvrðene su za sadraj proteina i šeæera. Sadraj proteina bio je najviši za<br />
hibrid ZP480 i u uslovima suše (13.6%) i u navodnjavanju (12.2%). Sadraj šeæera u<br />
navodnjavanju bio je najnii kod hibrida ZP360 (67.23%), a najviši kod hibrida ZP599<br />
(69.3%). U uslovima suše najviši sadraj šeæera bio je kod hibrida ZP360 (69.69%), a<br />
najnie vrednosti kod ZP599 (65.72%).<br />
Ovakva variranja u sadraju šeæera i proteina su posledica reakcije hibrida na razlièite<br />
uslove gajenja i osetljivosti prema suši. Rezultati mogu biti od znaèaja za preporuku<br />
hibrida u razlièitim regionima u Republici Makedoniji.<br />
CHEMICAL CONTENT OF THE MAIZE KERNEL IN DIFFERENT<br />
MATURITY GROUPS AND GROWING CONDITIONS<br />
This investigation has been established in two trial fields, during three years, where have<br />
been used irrigated field and non-irrigated field. The research has been performed in<br />
eight hybrids of maize (ZP360, ZP480, ZP599, ZP677, Stira, Colomba, Cecilia, and<br />
Constanza), which belongs to different maturity groups.<br />
The aim of this research was to identify duration of vegetative period in different growing<br />
conditions and to investigate chemical content of kernels.<br />
Regarding chemical content of basic metabolites into maize seed, the biggest variations<br />
were detected for protein and sugar content.<br />
The percent of proteins was highest in ZP480, in both the irrigated (12,2%) and drought<br />
(13,6%) location. The content of sugars in irrigated locations was lowest in ZP360<br />
(67,23%) and highest in ZP599 (69,3%). In the drought location highest percent of sugars<br />
was noted in ZP360 (69,69%), while lowest figure noted in ZP599 (65,72%).<br />
These variations are results of reaction of the hybrids to different cultivated conditions<br />
and their susceptibility to drought. The results of this paper could help to recommend hybrids<br />
for different regions of the agricultural complex in Republic of Macedonia.
