Research was directed to brackish drainage water use possibilities as well as drainage outflow decrease and water resources more rational use; water salinity limits for fine-fiber cotton irrigation and its impact on soil water-salt regime. Site is located 6-7rv to the north from Ashgabat. Climate is continental; relief-hilly plain. Soils to depth of 160cm are made of sand underlain by heavy loam, practically non-saline. Ground water level is 2-2.5m, salinity-2.8-5.0g/l, type of salinity is sulfate-chlorine. Site is equipped with means of measurement and account. Control plot was irrigated by fresh water. Based on results of study, possibility of drainage water with salinity 2.2-2.8 g/l use for irrigation on sandy soil is grounded. Recommendations    on irrigation technique and scheduling depending on water salinity were given.

Key words

Author: B.Myatiyev, O. Khadyrov Title: "Experience of saline water use for cotton irrigation on desert-sandy soils", Tashkent, SANIIRI, 1981 Field experience of brackish water use efficiency for irrigation of cotton on sandy soils is presented. Is found, that drainage water with salinity 2.2-2.8 g/l do not decrease fine-fiber cotton yield capacity to compare with control field where irrigation was done by fresh water.
