The researches on selection of optimal sowing rates for spring vetch seeds in mixed crops with filmy and naked oats in the conditions of the Non-Black Soil Zone on the basis of FSBSI FRC ‘Nemchinovka’ were carried out. Previously, researches were carried out with filmy oats, but with the inclusion of naked oats in the register of zoned varieties, a new goal is being set - to determine the possibility of using naked oats as a supporting crop for the legume component. The joint crops with spring vetch sowing rate of 1.2; 1.5 and 1.8 million germinating grains per 1 ha and with oats seeding rate of 3.0 million germinating grains per 1 ha were studied. The results of many years of researches have shown that for the yield of green mass in a mixture with naked and filmy oats, the most optimal sowing rate of spring vetch is 1.5 million viable grains per 1 ha. The maximum grain yields was achieved with a sowing rate of spring vetch of 1.8 million germinating grains with a filmy oat line. The grain yields in experiments with naked oats was significantly inferior to the standard.
