The paper presents the results of applying nitrogen fertilizers for spring wheat of the Novosibirsk 31 variety. The use of the fertilizers produced additional 1,62 t/ha of grain relative to the control variant. The maximum yield was 5,4 t/ha. The increased doses of the mineral fertilizers resulted in the increased ammonium ion in the grain, the rate reached 0,76 %. The excess of ammonium ion in spring wheat is neutralized by glutamine in the composition; the glutamine content reached 5,4 %. At the same time, the synthesis of arginine was reduced from 5,1 to 1,0 %.
