THE USE OF WATER AND RESOURCE SAVING TECHNOLOGIES IN INCREASE COTTON PRODUCTIVITY

Abstract

In this article, the Andijan-37 and Sultan varieties of cotton were treated with 6,000 kg of bentonite per hectare before additional plowing with mineral fertilizers (every 3 years) in the conditions of light gray soils. yield by 0.7%, cotton yield by 3.0-3.5 t/ha, and in the Sultan variety of cotton, the weight of 1000 seed seeds by 5 g, fiber yield by 1.4%, cotton yield by 4.1-4.5 an increase in ts/ha was observed. Due to 7-10 days early ripening of the cotton crop and its 90-100% compliance with the requirements of the first industrial grade, the net profit per hectare due to the saving of available resources by 20-25%. In comparison with the usual technology fed in the standards, it is reported that it increased by 192,197 and 553,113 soums, and by 468,048 and 553,148 soums in the Andijan-37 variety of cotton
