| Popis: | 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. |
