Summary

It is determined, that irrigation norm on evaporation deficit calculation will provide its decrease. Dependence of crop capacity on water availability level is established on a base of long-term researches. Empirical links of yield/maximum yield ration with water availability on 95,90,85,80%. Hydromodule rayons on administrative rayons are defined. Evaporation deficit  and its availability for the calculated years are computed. Coefficients of irrigation norms/medium size fiber cotton are calculated. It is determined, that loss under furrows irrigation is from 20 to 47,5%.

Key words
