The aim of the research is to study the effect of irrigation on the salt regime of the soil at various experimental sites. The production of cotton fiber with high technological quality is closely connected with the salt regime of the soil, because the excessive content of readily soluble salts in soils leads to a decrease in the yield of cotton. Studies have shown that the regime of irrigation of fine-fiber cotton exerts a noticeable influence on the change in the salt regime of soils. It has been established that in the irrigated lands of the Karshi step, which are susceptible to salinity to a weak degree, cotton should be used every year as a mandatory agrotechnical method for pre-sowing emergency preventive irrigation with the norms of 1200...1500 m3/ha. The effect of soil desalinization achieved by these waterings should be secured by applying optimal irrigation regimes for fine-fiber cotton during its growing season in conjunction with other agrotechnical measures carried out by intensive technology. With the introduction of such interlinked agro-meliorative measures, a precondition is created for maximum prevention of the movement of water-soluble salts from the lower, more saline layers to the upper ones.
