Using the Modern Method in Determination of The Irrigation Regime of Cotton in The Republic of Karakalpakstan

The article presents data on cotton irrigation planning, taking into account soil and hydrogeological conditions, natural and climatic factors of the region, and the cultivated variety. The study was conducted in response to the year-on-year increase in water scarcity in the Republic, including the Republic of Karakalpakstan. Existing meteorological indicators and the FAO methodology CropWat 8.0 program were used to plan cotton irrigation based on water demand. The scientifically based irrigation regime for cotton, developed by N.F.Bespalov based on the standard hydromodular zoning scale, according to the recommendations of scientists who conducted research in the conditions of the Republic of Karakalpakstan, provides for irrigation of cotton during the growing season in the northern zone: 3400 (IX) - 6400 (I) m3/ha and in the southern zone: 3800 (IX) - 7000 (I) m3/ha. Within the framework of FAO's CropWat 8.0methodology program, the cotton irrigation regime is planned using meteorological data from the region.
