Quality of winter soft wheat grain under the influence of repeated and intermediate sowing in cotton-grain rotation

Research work was carried out in 2017-2020 in a system of cotton-grain crop rotation on light gray soils of the Kashkadarya region of the Republic of Uzbekistan. This article describes the results of the positive effect of root and crop residues of mash and corn sown as repeat crops, as well as the sowing of intermediate crops of perco, rye as a green fertilizer in the soil on the quality of soft wheat grain in the crop rotation system.Grain quality improved due to the impact of a re-crop of mung bean sown after winter wheat and an intercrop of perco in a cotton-grain rotation system. Qualitative indicators of grain from year to year decreased as a result of the chronic sowing of wheat.
