| Summary: | In the article, the authors found that improving soil moisture with irrigation has a positive effect on the growth of cotton, but does not always have a positive impact on the number of bolls. According to the results of the research, it was found that the flowing waters of the Karshi steppe are located at a depth of 1.5-2.0 m and 3-4 m. It has been determined experimentally that the irrigated moisture content of cotton soil under light gray soil conditions is 70-75-65% relative to incomplete field moisture content. According to the research carried out in the first experimental area, the presence of seepage water on its surface, and the salinity of the soil showed the optimality of a particular regime.
