The article presents the results of field experimental research on selection of regionalized, new and promising varieties of cotton suitable for root system drip irrigation (TS) and their maintenance based on drought-resistant and resource-efficient technologies in the conditions of barren soils of old irrigated meadows of Surkhandarya region. In the conducted research, cotton varieties Bukhara-102 (control), Sultan, Istiqlal14, SP-1601, Surkhan-106 were watered before irrigation with respect to the limited field moisture capacity (ChDNS) in the control variants of 7070-60 percent, drip irrigation. and in the experimental options of irrigation, field studies were conducted on irrigation at 65-70-65 and 70-75-65 percent. As a result, in the southern climatic region of our Republic, the optimal irrigation procedure, irrigation rate and seasonal irrigation rates, as well as indicators of high temperature tolerance, were studied in the irrigation of local regionalized, new and promising varieties of cotton.
