THE INFLUENCE OF AGRO-TECHNICAL AND CHEMICAL WEEDS CONTROL MEASURES AND YIELD OF AUTUMN WHEAT IN ZARAFSHON VALLEY OF UZBEKISTAN

In typical irrigated gray soils of Uzbekistan, during weed control in winter wheat fields, tillage (plowing) was carried out in the fall at 30-35 cm. As a result, the agro-physical properties of the soil: a decrease in soil density by 0.02-0.04 g cm-3, an increase in porosity by 1.2-2.4%, water permeability in the period before planting (for 6 h) 702.0 m3/ha-1, wheat (Triticum aestivum L.) application at the end of the period was 596.3 m3 ha-1. In spring, simultaneously with soil cultivation to a depth of 30-35 cm, apply the herbicide Granstar-75% DF at the rate of 15 g ha-1, 86.8-95.7% of annual weeds in wheat fields and 28.0-38.2% of perennial plants. reduced to. On the basis of this applied agronomic measure, a scientific article describes the harvesting of grain from winter wheat up to 5.78-5.96 t ha-1.
