High energy content of dry corn mass makes it the most important silages crop, but the protein deficit of the corn should be supplied with some other crops - leguminous or cruciferous. The comparative productivity of corn (Zea mais) plantings mixed with leguminous crops (Glycine max) and quality of silages was analyzed. The research was made on sod-podzol light loamy soil. The analysis of the crop yield of the mono culture of the corn was made in the paniculation stage, milky and milky-wax ripeness. The productivity of the mixed sowing of the corn with different leguminous and cruciferous crops was analyzed by the green mass and dry substance key figures. The nutritive value of the pure corn green mass and corn-protein crops mixture was compared and analyzed. It was found that saturation of the corn silages with protein rich crops enables milk-yield increase for almost 5%
