Uticaj tipa zemljišta, količine azota i hibrida na sadržaj ukupnih proteina u zrnu kukuruza

Abstract

Ispitivanja uticaja tipa zemljišta, količine azota i hibrida na sadržaj ukupnih proteina u zrnu kukuruza obavljena su u trogodišnjem vremenskom periodu na lokalitetu Instituta za kukuruz "Zemun Polje" i u Rači Kragujevačkoj, po split plot planu u četiri ponavljanja. Na zemljištu tipa černozem sadržaj ukupnih proteina u zrnu bio je veći za 0,06% u odnosu na gajnjaču. Na oba tipa zemljišta, najveći sadržaj ukupnih proteina zabeležen je pri primeni 180 kg ha-1 azota. Najmanji sadržaj ukupnih proteina u zrnu utvrđen je u hibrida ZP 677 (7,90%), a najveći u hibrida ZP 434 (8,62%).

Investigations of the influence of soil type, quantity nitrogen and hybrid to the content of total proteins in maize grains were carried out over a three-year period at the locality the Maize Research Institute "Zemun Polje" and the Rača Kragujevačka, according to the split plot in four repetitions. The total protein content in the grain on chernozem soil was 0. 06% higher than the cambisol. The highest content of total proteins on both types of soil was recorded using 180 kg ha-1 nitrogen. The smallest content of total proteins in grains was recorded in hybrid ЗП 677 (7. 90%), and the largest in hybrid ЗП 434 (8.62%).
