In a short-term field experiment on medium-cultivated sod-podzolic soil of the Center of the Non-Chernozem Zone of Russia with a sufficient supply of nutrients and a weakly acid reaction of the environment, two-year studies established the conditions for obtaining high productivity of haylage mass of the lupine-wheat mixture, which provided more than 9 t/ha of dry matter with accumulation in it more than 14 c/ha of raw protein and up to 90 GJ/ha of exchange energy, as well as up to 36 c/ha of lupine grain in pure sowing and more than 32 c/ha in a mixture with spring wheat with accumulation in it respectively 12,3 c/ha and 7,84 c/ha of crude protein, 47,22 and 41,64 GJ/ha exchange energy, respectively. To do this, lupine in a clean sowing for grain should be sown with a sowing rate of 1.8 million/ha, in a mixture of 1,6-1,8 + 3,5 million/ha when cultivated on haylage on the background of a complete mineral fertilizer N50Р45К60, for grain P45K60
