The studies were conducted on a dark-grey forest soil with humus content of 4-5% P 2O 5 -10, K 2O – 12 mg/100g. The purple clover was sowed together with barley by a combined grain grass seeder SZT - 3,6. The seeding rate for clover is 15 kg/ha, for barley - 2,5; 3,0 and 4,0 million viable seeds per hectare. The mineral fertilizers were applied under the previous crop. Research results: optimal barley seeding rate with complementary seeding of clover is 3 million seeds/ha against the background of mineral fertilizers N 45P 50K 60.
