In the article results of researches on studying of influence of doses and terms of application of nitrogen fertilizers on a crop and quality of a grain of a spring triticale on the dark chestnut soils of the Akmola area are resulted. The greatest yield was obtained on the variant with application of N60 before sowing and on the variant with application of N30 before sowing + N30 in the tillering
phase against P60. On average, for three years the yield increase was 0.21-0.7 t/ ha. Against the background of P60 nitrogen fertilizers increased the protein content in the grain from 7.6 to 10.7%. Increase in fertilizer doses leads to an increase in the
grain yield, but the payback is 1 kg of active substance fertilizer grain is reduced.
