Summary

Research is devoted to studying possibilities of saline collector-drainage water use for irrigation in various soil-hydrogeological conditions, recommendations development on this water use in midstream of Syrdarya river. Hunger   Steppe   is  the  biggest  irrigated  region   in   Syrdarya midstream. Climate is sharply continental. Soils-bright sierozems; structure-light and medium loam. Salinity is light from surface, medium on depth of 60-100cm and with high gypsum concentration on depth of 80-140cm. There are two plots of 20ha each in state farm 16 and in farm 1-10 fields 5x5m. It is found, that under irrigation with water which salinity is higher than 2.5g/l soil properties are getting worse. Scientific grounding is given of saline drainage water usefor irrigation with minimal risk for soil productivity and environment on example of Hunger steppe.
