Abstract. The article presents the results of studies on the effect of optimization of organic and mineral fertilizers on the yield of green mass and indicators of the quality of forage on stubble crops of mixed cultivated crops on poorly supplied with nutrients gray-meadow soils. The introduction of optimal rates of organic and mineral fertilizers on stubble crops of mixed crops of corn and sorghum increased the yield of green mass. With a yield of green mass of 372 c/ha in the control variant of mixed crops without fertilizers, in the variant of introducing the norm N120P150K150, this figure was 627 c/ha, which is 255 c/ha more in comparison with the control, i.e. by 68 %. It has been found that the introduction of optimal rates of organic and mineral fertilizers on stubble crops of mixed crops of corn and soybeans, along with an increase in the yield of green mass, has a positive effect on its quality indicators. Based on the research results, it was found that to achieve a high yield of green mass of joint crops of corn and soybeans, it is effective to introduce mineral fertilizers at the rate of N120P150K150 and the joint use of organic and mineral fertilizers at the rate of 10 t/ha (manure) + N70P125K90.
Keywords: fertilizers, fertility soil, stybble crops, mixed crops, protein, green mass, yield, feed unit.
