The article deals with the introduction and operation of drip irrigation systems using water-saving technologies for the cultivation of “Sultan” cotton in the Jarqurghon massif of the Denau branch of “Surkhan Sifat Tekstil” LLC in Jarqurghon district of Surkhandarya region. The results of theoretical and field experimental studies conducted in 2018-2019 are presented. In changing the natural climate and economic conditions of the region under consideration, the authors first determined the values of reliability and operational reliability of the main joints and the entire drip irrigation system. High efficiency and reliability of drip irrigation systems are ensured due to their high design and high-quality construction and installation work. The operation of the system is constantly monitored for the implementation of all activities provided for in the business plan of farms. Therefore, the work on ensuring the technical and working condition of drip irrigation systems, improving the reclamation of lands, maximizing productivity and operation has helped

The article presents theoretical and field experimental data on determining the rates of infiltration and filtration of irrigation water in the soil - grounds of the calculated layer in the cotton fields of the Dzharkurgan massif in the Surkhandarya region. Based on the established values of the rates of infiltration of irrigation water, the drip irrigation regime for cotton of the new Sultan variety has been determined, the parameters of the innovative drip irrigation technology have been determined.

Today, due to global climate change, the demand for irrigation water is growing in every part of the world, so the rational use of available water resources requires the management of water resources through water-saving technologies. It is necessary to analyze data on the rational management and efficient use of limited water resources in the country, to continuously increase the efficiency of water resources in the field, to expand the use of water-saving irrigation technologies and their application in production, and to eliminate excess water loss.
