The effect of increasing application rates of nitrogen fertilizers on the yield and quality of spring wheat grain was studied. It was found that fertilizers provided for 69% of wheat grain yield, and the application of N60 increased the productivity of wheat cultivars compared to the conventional PK fertilization. For the short-stem high-protein cultivar Irgina, the application rates of nitrogen fertilizers should be no lower than 60-90 kg/ha to obtain grain of high baking quality.
