When drip irrigation is used in an experimental field planted with cotton in the conditions of light sandy loam soils of Surkhandarya region, the level of seepage water is 1.5-2.0 m, the moisture content of the soil before irrigation is 70 compared to ChDNS. When -85-65%, cotton was watered 4 times according to the 0-4-0 scheme. Cotton was not irrigated during the period from germination to flowering, cotton was irrigated four times during the period of flowering and fruiting with irrigation rates of 616–651 m3/ha, seasonal irrigation was yorarii – 2521–2537 m3/ha. or 1594-1633 m3/ha of irrigation water was saved compared to the control option. The promising effect of drip irrigation compared to other irrigation methods and the results of experiments conducted to study the effect of this irrigation technology on the growth, development and productivity of cotton are presented.
