In this article, in the conditions of light gray soils of Andijan-37 and Sultan varieties of cotton, before additional application of mineral fertilizers (every 3 years) 6,000 kg of bentonite per hectare is cultivated with Andijan-37 variety of 1,000 seeds weighing 2-3 g/ha, fiber yield 0,7%, increase in cotton yield by 3.0-3.5 q/ha, in the Sultan variety of cotton the weight of 1000 seeds by 5 g, fiber yield by 1.4%, cotton yield by 4.1-4.5 q/ha observed an increase in Due to the early ripening of the cotton crop 7-10 days and its 90-100% compliance with the requirements of the first industrial variety, saving 20-25% of available resources, the net profit per hectare is 150-105-75 kg/ha of mineral fertilizers used in the Sultan variety of cotton. There is information that in comparison with the usual technology fed on norms increased by 192,197 and 553,113 UZS, cotton of Andijan-37 variety increased by 468,048 and 553,148 UZS.
