Abstract

The features of changing the productivity of spring wheat under the influence of weather conditions and after foliar  application with humic acid fertilizers, mineral and organic-mineral fertilizers are considered. It is shown that at 56% of the norm of precipitation for vegetation and air temperatures fall above the annual average by 4–7 ° C, the yield of spring wheat decreases by 0.85 t / ha or by 41%. After three-year experiments, it was noted that, under the influence of the studied agricultural practices, the yield of spring wheat increases as well as the grain quality of this crop. The highest yield was in the variants after application of Biocomplex and Biohumus; it was 1.76 and 1.71 t / ha, respectively, which is 29.4 and 25.7% higher than the control. Organic and mineral fertilizers containing a complex of microelements and organic acids had a greater effect. Thus, the protein content   was up to 17.6%, dry gluten – up to 30.8%, raw gluten – 33.5%, IDK was 78.2 units.
