The theoretical substantiation of the joint red clover and honey-clover planting is presented. The productivity of a given grass mixture is given in comparison with the monoculture of both crops. The coefficients of the biological activity of two mixed planting methods are shown. The characteristic of the microlandscape method of planting of legume-grass mixture is outlined, the main theoretical prerequisites of the increase in the yield of the both mixture components are considered. The data on the yield of alfalfa-oat mixtures, when two sowing methods are used, are analyzed and compared with the monoculture of the both mixtures. The greatest productivity of lupine seeds in a mixture is received at microrelief method of sowing - 73% from the control of monoculture and 146% in comparison with smooth crop, and within years of agrobackground P60K120 the given parameter reached 82% from the control. On the average for the years of research productivity of oats in structure of mixture at microrelief method of sowing has made 76% from a parameter of the control of monoculture, and at smooth sowing only 56% from the control. The total harvesting of grain of oats and lupine on the microrelief variant exceeded yield of lupine in monoculture on 95% and yield of oats in monoculture - on 22%. At the smooth method of sowing the similar parameter was more than lupine yield in the pure state on 40% and less than oats yield in the pure state on 13%. Yield of lupine - oats mixture, received with 2 hectares of the microrelief variant, on the average for 5 years, was on 50,4% more, than total yield of monoculture of oats with 1 hectare and monoculture of Lupine with 1 hectare. The similar parameter at the smooth method of sowing of mixture was only on 7,5% more than total yield of monocultures
