Abstract
The effect of organic fertilizers and biostimulants on the growth and development of spring barley plants under the conditions of the Donetsk region manifested itself in the improvement of yield structural indicators and its increase. The coefficient of productive tillering proved to be the highest (1.44) under the application of the biostimulant regoplant against the background of biohumus-1 with N15P15K15. The largest number of grains in the ear was against the background of N30P30K30, and also against the background of biohumus and N15P15K15 with additional spraying of crops with regoplant and stimpo, the increment over the control being 1.8−2.5 pcs.of grains. The maximum weight of 1000 grains (44.6 grams) was with the joint use of biohumus-1 with N15P15K15 in combination with biostimulants. Complex application of biohumus and biostimulant regoplant provided a yield of 2.95 t/ha, the increase was 0.66 t/ha or 28.8% compared to the control. The use of biohumus of various origins can reduce the costs of mineral fertilizers, thereby reducing the anthropogenic load on agricultural landscapes while maintaining the yield level.
