Fertilizers and biological products used for cultivation of perennial grasses on gray forest soils of the Middle Volga region

Abstract

In recent years, fertilizers and biological products are widely used for cultivating perennial grasses to form highly productive agrocenoses and reduce the cost of feed. The issues of the use of biologically active substances for pre-sowing seeds of perennial herbs in combination with leaf fertilizing are of great practical importance. In the soil and climatic conditions of the Middle Volga region, the pre-sowing seed treatment with Azotovite 2 kg/t in combination with leaf treatment with Flavobacterine 4 l/ha depending provided an additional yield of 2.5–4.8 t/ha of green mass with a content of 440–960 feed units. The effect of the above biological products is equivalent to the application of 70–88 kg/ha of mineral fertilizers and cost savings in the amount of 1.5–1.9 thousand rubles/ha.
