The article studies the effects of organo-mineral compost, manure, and mineral fertilizers on the growth and development of cotton. The use of different types of compost and amounts of manure increased soil fertility and had a positive effect on the growth and development of cotton. In this study, the effect of organo-mineral composts on the growth and development of cotton under saline soil conditions was investigated. The experiment involved the application of various rates of organic fertilizers (10, 15, and 20 t/ha), composts (12, 14, 20, 22, and 24 t/ha), and a 25% reduced dose of mineral fertilizers in combination. Key growth indicators such as main stem height, number of fruiting branches, and number of bolls were analyzed. In the control variant, the number of fruiting branches was 11.8, and the number of bolls was 8.3 per plant. In the treatments where organo-mineral composts were applied, these indicators increased significantly. Specifically, in the variant treated with 22 t/ha of compost, the number of fruiting branches reached 15.1 and bolls 11.5 per plant, which is 3.3 and 3.2 higher, respectively, compared to the control. The results of the study demonstrate that organo-mineral composts can enhance the vegetative growth phases of cotton, increase yield components, and reduce the need for mineral fertilizers. This, in turn, contributes to environmentally sustainable and efficient use of land resources.
