Features of barley crop formation when using morphoregulators and biofertilizers in various weather conditions

Abstract

The results of the conducted studies have shown that spring barley under different meteorological conditions of the growing season reacts differently to the treatment with growth regulators and the introduction of biofertilizers. In conditions of lack of moisture, the treatment of plants with growth regulators does not reduce the height of plants, but at the same time reduces the yield of the crop, depending on the type of retardant, by 0.82-1.52 t / ha. HEFC, BP and Hardy, R. have a significant effect on the yield in arid conditions. Moreover, the use of the drug Hari in its pure form reduces the yield of barley by 0.9 t / ha, and with the combined use of the drug Hardy, P with biofertilizers, the yield of barley practically does not decrease.
