USE OF RESOURCE-SAVING TECHNOLOGIES IN GROWING WINTER WHEAT | Journal of Global Agriculture ......

The materials on the study of the need for winter wheat during the growing season to the norms of mineral fertilisers and irrigation regime during the growing season with the additional use of various bentonite clays for ploughing in conditions of typical grey soils of the Tashkent region from 2008 to 2011 are presented in this article. According to the findings, introducing 3000 kg/ha of bentonite clay under arable land and irrigation of winter wheat during the growing season at a moisture content of 60–70–60 percent of the soil LFMC resulted in a decrease in the bulk density of soil in a layer of 0–30 cm by 0.03–0.05 g/cm3, and increasing soil water permeability by 30 m3/ha in layers of 30–50 cm on average up to 0.07 g/c In comparison to the control variation, the irrigation rate was reduced to 780–810 m3/ha, resulting in an extra grain yield of 11.9 centners/ha. Before sowing winter wheat, the introduction of 3000 kg/ha of bentonite clay under arable land, and irrigation during the growing season at a moisture content of 70–80–70 percent of the soil LFMC, a decrease in the volumetric mass of soil in a layer of 0–30 cm by 0.07–0.08 g/cm3, and in layers of 30–50 cm, on average, up to 0.11 g/cm3, an increase in soil water permeability by
