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