Experiments were conducted on studying the effects of organic and mineral fertilizers on the growth, development and productivity of cotton in saline soils of the Republic of Karakalpakstan. In practice, the annual norm of mineral fertilizer (N250 P175 K125 kg / ha) was reduced by 25% (N185 P130 K90 kg / ha) and an additional 10 and 20 t / ha of organic fertilizer was used. As a result of the experiment, when organic fertilizer was used at the amount of 20 t / ha, and mineral fertilizer was used at the amount of N185 P130 K90 kg / ha the growth, development and productivity of cotton were improved and mineral fertilizer was economized by 25%.
