Abstract
The studies were conducted on the experimental field of the All-Russian Research Institute of Phytopathology in 2016-2018 in two field experiments on sod-podzolic heavy loamy soils. The aim of the research was to select among the widest range of forage crops the most productive ones with high nutritional value and low cost for organizing green and raw materials conveyors in order to make more rational use of labor and technical resources. Among the annual crops and mixtures, the most productive for three years on average were sunflower, Sudan grass, white lupine and oats: the crop of fodder units was respectively: - 49.9; 50.9; 49.9 and 47.9 centners per hectare; mixtures with peas, they are inferior to single-species crops due to pea damage by powdery mildew and pea weevil, and white sunflower with lupine ensured an equal collection of feed units — 49.9 centners per hectare and the highest provision of digestible protein —127 g in 1 fodder unit. Of the perennial grasses yellow-hybrid alfalfa and timothy grass, which it is expedient to grow in mixed sowing to increase the productive longevity of herbs and reduce the cost of feed, proved to be the most promising.
