The aim of the research was to investigate the effect of different doses of N on the yield and quality of winter wheat grain grown on two phosphorus backgrounds (low and high) in Kazakhstan. Results show that the content of proteins in wheat grain was influenced mostly by the level of nitrogen supply, and not by the ratio between nitrogen and phosphorus. Phosphorus had not any specific effect on the fractional composition of proteins and the content of amino acids. The content of gluten increased due to the addition of N, while albumin and globulin were not affected by N nutrition level.
