Summary. Under conditions of the southwest of Bryansk region of Russia the experiment on combined effect of mineral and organic fertilizers on productivity and quality of grain of winter rye under conditions of radioactive contaminated soils was carried out. The increase in the application of mineral fertilizers promoted reliable growth of grain productivity of winter rye up to 1.04 t/ha and raised the content of amino acids in winter rye grain. Combined application of organic and mineral fertilizers increased productivity of grain 2.2 times, in comparison with the control, and the content of amino acids grew to 73.0 g/kg (in the test variant 20 t of manure + N₉₀P₆₀K₉₀). The accumulation of macronutrient elements in production practically did not depend on the studied systems of fertilization. The variability of this indicator was within 0-0.02%. Specific activity of winter rye grain in control variant on the average over years of the study did not exceed the standard and was 58 Bq/kg. Application of organic fertilizers in addition to N₉₀P₆₀K₉₀ promoted statistically reliable decrease in the content of ¹³⁷Cs (30 Bq/kg with LSD05 equal to 6), in comparison with the variant with mineral fertilizers.

Keywords: winter rye, productivity, serradella, amino acids, macronutrient elements, ¹³⁷Cs.
