The article presents studies conducted in 2015 - 2018. in the field of stationary long-term experience. It was found that the studied fertilization systems made it possible to increase the yield of spring barley grain from 90 to 120% in comparison with the control, nitrogen removal of 1 ton of grain with the corresponding amount of straw - by 4-6 kg. The payment for the applied fertilizer systems was the highest in the variant where 44 kg of a.i. / ha were applied. An increase in fertilizer doses up to 210-230 and more kg a.i. / ha showed a tendency towards a decrease in the payment for fertilizers by the crop.
