The effects of the application of increased ratios of nitrogen on the grain yield and quality of soya bean cultivars of different maturity groups were studied. The three-year study was conducted in the experimental field located in southern Banat (Serbia). The soil belongs to the chernozem type with optimum physical and chemical properties. The cultivars Sava, Valjevka, Proteinka Diva, Venera and Mima were used in this study. The system of top dressing of plants with nitrogen included the following ratios of nitrogen: 50 kg/ha (N1), 100 kg/ha (N2) and 150 kg/ha (N3). The control variant did not include top dressing with nitrogen (N0). Field experiments were set up according to the split-plot system with four replications. The results showed that all six cultivars had high genetic potential, which did not significantly increase with increasing ratios of nitrogen. Grain yield was the highest in a year with the most favourable distribution of rainfall (2007). The total protein content in grain was important for the research, cultivars and nitrogen ratios. The oil synthesis and accumulation in grain were mainly influenced by weather conditions during the experiments, cultivars, while nitrogen had no effect on this indicator of quality.
