Abstract
The aim of the study was to analyze the effect of different amounts of nitrogen on seed yield and quality of selected varieties with different length of vegetation period, specific corn characteristics and from different breeding Institutes. Trials were conducted on tchernozem soil type on the experimental field in the Maize Research Institute in Zemun Polje. Based on the results obtained it can be concluded that all fertilization variants increased the seed yield from 3.6% (P60K60 variant) to 12.2% (N90P60K60 variant). Fertilization variants had lower positive effect by increasing the seed protein content and was from 0.4% (P60K60 variant) to 4.0% (N90P60K60 variant). Negative correlation between seed protein and oil content was determined.
U radu je prikazan uticaj različitih količina azota na prinos i kvalitet sorata soje, različite dužine vegetacionog perioda i specifičnih svojstava zrna, iz različitih selekcionih kuća. Istraživanja su obavljena na zemljištu tipa černozem na oglednom polju Instituta za kukuruz u Zemun Polju. Dobijeni rezultati pokazuju da su sve varijante đubrenja povećale prinos zrna soje u intervalu od 3,6% (varijanta đubrenja P60K60) do 12,2%(varijanta N90P60K60). Slabiji efekat varijante đubrenja imale su u pogledu povećanja sadržaja proteina u zrnu soje. Kretao se u intervalu od 0,4% (varijanta đubrenja P60K60) do 4,0%(varijanta N90P60K60). Utvrđena je negativna korelacija između sadržaja proteina i ulja u zrnu soje.
