dc.description.abstractThe aim of the present study was to observe the response of maize hybrids under rainfed and irrigation conditions of the soil in order to establish the dependence of yielding potential on the water amounts reaching the soil surface during the growing season. The four-replicate trail was set up according to the randomised complete-block design on chernozem. Pre-watering soil moisture was approximately 70% of field water capacity, and soil moisture was established thermogravimetrically. During the five-year studies, the following differences in yields could be as follows: 12.68 t ha-1 (ZP 341); 12.76 t ha-1 (ZP 434); 13.17 t ha-1 (ZP 578); 14.03 t ha-1 (ZP 684) and 13.75 t ha-1 (ZP 704) under conditions of 440 mm, 440 mm, 424 mm, 457 mm and 466 mm of water, respectively. The hybrid ZP 341, i.e. ZP 578 expressed the highest, i.e. the lowest tolerance in dry relative seasons, respectively. The reduction of the water amount for every 10 mm decreased the yield by 119.4 kg ha-1 (ZP 341), 156.7 kg ha-1 (ZP 434), 172.3 kg ha-1 (ZP 578), 148.9 kg ha-1 (ZP 684) and 151.1 kg ha-1 (ZP 704).en
dc.description.abstractCilj rada je bio proučavanje genotipova kukuruza u prirodnom i irigacionom vodnom režimu zemljišta, kako bi se utvrdila zavisnost korišćenja potencijala rodnosti od količine vode koja dospeva na površinu zemljišta u toku vegetacionog perioda. Ogled je izveden na černozemu, po metodi blok sistema u četiri ponavljanja. Predzalivna vlažnost zemljišta iznosila je oko 70% od poljskog vodnog kapacitete, a sadržaj vlage u zemljištu određivan je termogravimetrijskom metodom. Za petogodišnji period proučavanja, različite količine vode uticale su da se između varijanti sa i bez navodnjavanja, u proseku ostvare sledeće razlike prinosa po hibridima: 1,33 t ha-1(ZP 341); 1,53 t ha-1 (ZP 434); 1,77 t ha-1 (ZP 578); 1,66 t ha-1 (ZP 684) i 1,54 t ha-1 (ZP 704). Analiza pokazuje da se maksimalni prinosi mogu očekivati na nivou sledećih vrednosti: 12,68 t ha-1 (ZP 341); 12,76 t ha-1(ZP 434); 13,17 t ha-1 (ZP 578); 14,03 t ha-1(ZP 684) i 13,75 t ha-1(ZP 704) u uslovima, redom 440 mm, 440 mm, 424 mm, 457 mm, 466 mm vode. Najveću tolerantnost prema suši ispoljio je hibrid ZP 341, a najmanju ZP 578. Smanjenje količine vode za svakih 10 mm, umanjuje prinos za 119,4 kg ha-1 (ZP 341), 156,7 kg ha-1 (ZP 434), 172,3 kg ha-1 (ZP 578), 148,9 kg ha-1 (ZP 684) i 151,1 kg ha-1 (ZP 704).sr
