aref2 1 Among cultivated crops winter wheat in comparison with spring wheat takes the leading position in Russia and ensures higher and more stable yields. It provides one-third of the total gross yield of wheat, being the main food crop. In the south-west of the Central Region of Russia the leading factor of grain yield increase and its quality remains the use of mineral fertilizers, nitrogen being the limiting factor of its productivity growth. For all the experimental years on the variant of the experiment with the norm N64P64K124 +N30+N30 the average yield amounted to 5.3 t/ha (5.3 % lower compared to the variant with N98P64K124 +N30+N30). On the variant with N64P64K124 + N30 the average yield was 4.8 t/ha, being 14.3 % lower in comparison with the variant N98P64K124 +N30+N30. The control data were 2.7 t/ha, being almost two times lower than at the variant N98P64K124 +N30+N30. The most productive year on all fertilizer backgrounds was 2014. The influence of moisture content and heat supply, and the effect of different rates of mineral fertilizers on the change in the yield of grain, productive plant stand and the content and quality formation of crude gluten have been established. In the years of experiments hydrothermal coefficient has a direct and profound impact on the value of yield in the vegetation period "April-May", it being described by the equation Y = 2.79 + 1.10. For the period "June-July" there was a feedback between moisture content and crop capacity (Y = 5.94 - 1.08), as well as between the hydrothermal coefficient and the accumulation of gluten (Y = 31.66 - 3.02X). In general, during the research years the highest crop capacity of 5.6 t/ha with the content of crude gluten to 30.3 % was formed on the variant N98P64K124 + N30+ N30. It is established that a sufficient level of mineral nutrition provides not only planned productivity, but also the quality improvement of winter wheat grain.
