Summary

Investigations related to development of complex measures on strengthening ground water withdrawal by wells of vertical drainage, rationalization of surface and ground water resources combination as well as limited water resources re-allocation between farms.   Arus-Turkestan massive related to Burgun and Turkestan rayons.Climat is sharply continental. Irrigated area -52,4 th.ha In Burgun rayon ground water depth is 1,5-2,5m with salinity -1-3 and 2-5 g/l.In Turkestan rayon ground water depth is 4-7m and more, salinity up to 1 g/l. Soils are saline, chloride-sulfate and sulfate type. Irrigation from Turkestan main canal, efficiency -0,77.Five farms have been selected for investigations conduction.

According to results scientific grounded recommendations on optimal ground water withdrawal and water resources re-allocation for rational water availability of irrigated lands creation are developed.

Key words
