Two-year results of research the cultivation of white sweet clover in compatible crops with annual cereal forage crops in the Right-bank forest steppe. It was determined the impact of norm of seeding of white sweet clover and fertilization on species composition, for the best cereal components to create the mixed high performance. >4s a result of studies was found that index of compatible sowings white sweet clover with annual cereals depend from weather conditions, species composition of mixtures, seeding rate of white sweet clover and fertilizing. The biggest number of shoots (517 pcs/m2) was featured in single-species cultivation white sweet clover and seeding rate 20 kg/ha and fertilizing N60Pg0Kg0.The highest density of standing on all variants of compatible cultivation (up to 6-17% higher in comparing to control) was received with seeding rate of white sweet clover 20 kg/ha. Applying of mineral fertilizer in rate N60Pg0Kg0 on compatible sowings had a most significant impact on their density, providing increasing of index 5-12% in comparing with the variant without fertilizers. Among grass mixtures the highest density (422 pcs/m2) was recognized for compatible cultivation with millet, seeding rate of white sweet clover 20 kg/ha and fertilizing N60Pg0Kg0.
