Substantiation of technology of using collector-drainage water for cotton irrigation

The article has developed the optimal options for the use of collector-drainage water as an additional source in the active layer of soil during irrigation of collector-drainage water of cotton variety "An-Bayaut-2" in Saykhunabad district of Syrdarya region, which is 567 m 3 /ha. Innovative technologies for irrigating cotton with collector-drainage waters using the nuclear-physical method for determining the dynamics of water absorption in the active layer of soils with low salinity allow achieving water saving and a high yield of cotton 4.68 c/ha, saving 13-14% of river water and additionally net income in the amount of 1,150,000 UZS per hectare.
