Abstract

In a field experiment carried out in the conditions of meadow-takyr soils, the effect of manure and mineral fertilizers on the elemental composition, nutritional regime of the soil and cotton yield was studied. At the same time, in the variants where mineral fertilizers were used at a rate of N250 P175K125 and organic and mineral fertilizers together at a rate of N250 P175K125 +30 t/ha of manure, the number of bolls per plant and cotton yield significantly increased compared to the control without fertilizers. At the same time, in the N250 P175K125 option, the number of bolls per plant was 15.8 pieces, the cotton yield was 41.56 c/ha, and in the option where mineral and organic fertilizers were used together - N250 P175K125 +30 t/ha of manure, these indicators were 17.8 pieces and 43.98 c/ha, respectively.
