In this article, stratified feeding of Bukhara-102 variety of medium-fiber cotton with mineral fertilizers were carried out in the conditions of irrigated and fertile soils of Kashkadarya province. Simultaneously, compared to the studied fertilizer application options, there was a decrease in soil volume by 0.01–0.02 g/cm3, an increase in soil porosity by 0.4–1.2%, and an increase in soil water permeability to 5.8–24.6 m3/ha. Moreover, an additional yield of 1.3–2.6 quintals of cotton, the quality indicators of fiber length that increased by 0.1–0.2%, fiber yield to 0.2–0.5%, the weight of 1, 000 seeds to 1–2 grams , the incidence of Wilt's disease was found to become as low as 6.1–10 %. At the same time, with increasing salinity in the care of saline soils at different levels, the net profit was around 40, 617 - 1, 127, 853 UZS and the profitability rate was 0.8-20.1% lower than expected.
