Abstract: The article the influence of a hybrid, a background of mineral nutrition, non-root top dressing with various preparations on the productivity and economic efficiency of the production of green and dry mass of corn. It is shown that in the conditions of the North-East of the Central Non-Chernozem region, modern domestic corn hybrids – «Ross 199 MV» and «Voronezh 158 SV» are able to form yields on an organic background with an efficiency of 2.5% – 65 t/ha of green mass with ears in milk-wax ripeness. The most economically profitable is the cultivation of the «Voronezh 158 SV» hybrid against the background of the introduction of 80 t/ha of manure + N80 with the use of foliar fertilization with complex fertilizer Aquarin 5, which provided the highest conditional net income (104.4 thousand rubles/ha), a higher level of profitability of production – 144.6%, the lowest cost of feed – 1041 rubles./t
