Abstract
The aim of this study was to analyze the effect of increasing amounts of nitrogen on productivity of soybean genotypes under different agroecological conditions. The investigations were conducted on two locations: Maize Research Institute, Zemun Polje (tchernozem soil type) and Kloka village (private property, brown forest soil type). Field micro experiments were conducted by split-plot method in four replications. Given results show, on average for both soil types, increasing values of grain mass per plant and yield using 30 and 60 kg ha-1 of nitrogen for 7.1% and 7.5%, respectively. Fertilization variant using 90 kg ha-1 of nitrogen gave lower values of examined parameters compared to the fon (P60K60) for 5.4% and 5.7% respectively.
U radu su prikazani rezultati ispitivanja uticaja rastućih količina azota na produktivnost genotipova soje u različitim agroekološkim uslovima. Istraživanja su obavljena na dva lokaliteta, u Institutu za kukuruz 'Zemun Polje' (zemljište tipa černozem) i u selu Kloka (privatan posed, zemljište tipa gajnjača) - donja Jasenica 2009. godine. Poljski mikroogledi izvedeni su metodom razdeljenih parcela (split plot), u četiri ponavljanja. Dobijeni rezultati pokazuju da su se, u proseku za oba tipa zemljišta, masa zrna po biljci i prinos povećavali upotrebom do 60 kg ha-1 za 7,1 odnosno 7,5%. Varijanta đubrenja sa 90 kg ha-1 dala je niže vrednosti ispitivanih parametara u odnosu na osnovu-fon (P60K60) za 5,4% odnosno 5,7%.
