INTRODUCTION 
Relevance of the dissertation topic:
: Today, using new innovative 
technologies for watering and feeding cotton, it is possible to evenly moisten the 
active soil layer with plant roots and increase the utilization rate of mineral fertilizers. 
When the optimal mode of moisture, air, heat and nutrition for the plant is established 
in the soil, its growth and development are accelerated, and a high and high-quality 
crop is obtained. The use of water- and resource-saving technologies in the care of 
cotton when irrigated and fertilized with mineral fertilizers gives positive results. In 
recent years, such agricultural activities as digging cotton in cotton fields and 
distributing water to the fields through artificial flexible pipes, watering by laying a 
plastic film between rows, applying mineral fertilizers dissolved in water, not only 
water, ensure savings and efficient use of fertilizers. In particular, the Decree of the 
Republic of Uzbekistan dated March 1, 2022 No. PQ144 “On measures to further 
improve the implementation of water-saving technologies in agriculture” eliminates 
the existing shortcomings and problems in the implementation of water-saving 
technologies. In order to mitigate the negative effects of water scarcity observed in 
the region, as well as to pay special attention to increasing efficiency through the use 
of water-saving technologies in order to more efficiently use water resources in the 
cultivation of crops, by the Decree of the Republic of Presidential Decree of March 1, 
2022, PC- 145 “On measures to improve water resources management in the 
downstream chain and regulate relations between water users” effective water 
resources management, their important tasks, such as accounting and reporting, 
improving relations between water consumers and involving the private sector in 
these processes. Based on them, the predicted coverage of 600,000 hectares of fields 
with drip irrigation technology in the republic was confirmed. 
Based on this, the solution of existing problems related to the efficient use of land, 
water and other material resources in the republic is one of the urgent tasks of the 
agro-industrial complex. In the research, scientists of the Scientific Research Institute 
of Agrotechnical Selection, Sowing and Cultivation of Cotton (NIAGHT) set the 
main goal of developing economical methods for irrigating cotton in conditions of 
typical gray soils of the Tashkent region. At the same time, cotton irrigation was 
studied by comparing drip irrigation and drip irrigation methods.
