INFLUENCE OF HERBICIDES AND FERTILIZERS ON YIELD AND QUALITY OF BARLEY GRAIN
The results of three-year studies of the effect of multicomponent herbicides used on two backgrounds of mineral nutrition N54P54K54 and N70P70K70 on the infestation of barley crops with juvenile and perennial weeds, yield and quality of barley grain are considered. It was found that the use of herbicides Secateur Turbo, Bomba, Demeter Mix and tank mixture of herbicides Foxtrot and Dianat provides high biological efficiency up to 84-90%, due to the suppression of monocotyledonous and dicotyledonous weeds. The highest efficiency against weeds and the yield of barley grain in experiments was obtained on the variant with Dianate and Foxtrot on the background of fertilizers N70P70K70 - 3.49 t/ha. The use of herbicides and fertilizers helps to increase the protein and dry matter content in the barley grain.
