Abstract

In a long-term stationary field experiment of the Novozybkovsky State Agricultural Experimental Station of the All-Russian Research Institute of Lupine on sod-podzolic sandy soil contaminated with ¹³⁷Сs 526-666 kBq / m². the effectiveness of chemical means for cultivating winter rye Pukhovchanka was studied. It was established that the use of organic-mineral (aftereffect of manure 40 t / ha + N₇₀P₃₀K₆₀) and mineral N₁₄₀P₆₀K₁₂₀ fertilizer systems in combination with chemical plant protection products and a humistim biological product can increase the yield of winter rye grain by 4.1 - 4.4 times compared to control. The complex use of fertilizers. pesticides and humistima contributed to a significant increase in the physical and baking indicators of grain quality relative to control. The use of fertilizer. both separately and in combination with chemical plant protection products and humistim. reduced the accumulation of ¹³⁷Сs in winter rye grains by 1.95 - 5.60 times compared with the control. which ensured the production of normatively clean products in technologically polluted areas. The greatest energy and economic efficiency was noted in the organic-mineral fertilizer system in combination with pesticides and a humistim biological product. where the profitability level of winter rye grain production was 92.6%.
