Productivity and nutritional value of Sudanese grass when cultivated for green fodder

Abstract

Increasing the productivity and quality of forage crops is a necessary condition for creating a solid feed base that will ensure the full feeding of farm animals. The paper considers the results of studies on the influence of mineral fertilizers and pre-sowing seed treatment with Raikat Start on the production processes of the Sudan grass of the Julia variety on chestnut soils in the Lower Volga region. It was found that the highest yield of green mass of Sudan grass 28.6 t / ha was formed on the variant with the introduction of mineral fertilizers at a dose of N120 P120 K90 + N30 and the growth stimulator Raikat Start, the increase to the control was 9.3 t / ha. This variant also showed a decrease in the fiber content and an increase in the proportion of pro-tein from 7.05 % in the first cut to 8.28 % in the third cut. The application of mineral fertilizers in the studied dose provided a green mass of Sudan grass that was safe for agricultural animals with a nitrate content of no more than 407 mg/kg.
