Summary

Studies are dedicated to the development of biologically optimal regime of forage beet irrigation providing maximum crop yield and high effectiveness of water-land and other resources use in conditions of Central Tadjikistan. EPP is located in Gyssar valley at the altitude 641-1215 m. Soil - semi-loam. Ground water table - 1.5-3 m, mostly fresh (up to 1 g/l) or slightly saline (1-3 g/1). EPP area - 1.5 ha. Irrigation source - Big Gyssar canal, water salinity degree is at least 0.7 g/1. Irrigation network - in earthen channel, efficiency 0.85-0.90. Plot is equipped by water account means. In result of studies it has been established that biologically optimal and economically expedient forage beet irrigation regime under conditions of dark gray desert soils of Gyssar valley is irrigation with soil humidity at level 70% normal humidity during growing period. To perform this purpose 7 irrigations are carried out according to scheme 2-4-1 with irrigation norm 5700 m3/ha. 150-160 t/ha root crops and 18-20 t/ha vegetable tops.

Key words
