Abstract

In our republic, biostimulants are important in growing high and quality crops from agricultural crops. Special attention is being paid to uniform harvesting of seeds, improvement of disease tolerance and improvement of cotton growth and development, as well as high and highquality cotton yield and wide introduction. Humic stimulants are ecologically friendly, economically cheap and innovative. Nowadays, in world practice, the scale of using humus-based stimulants is increasing in order to increase soil fertility and the efficiency of using nitrogen and phosphorus fertilizers, to accelerate the growth and development of plants. In the conditions of typical gray soils of Tashkent region, humic-based stimulators before sowing seeds, when used in the optimal period and norms, the germination of seedlings is accelerated by 10-15%, and when processed in the optimal period and norms of cotton during the 2-3 Chinese leaves, combing and flowering periods, the growth and development of the plant improves, physiological as a result of the acceleration of the processes, it was found that the cotton yield increased by 4.0-6.0 tons/ha.
