Irrigation and Melioration

Abstract

In this paper mentioned scarcity of water resources in the country, also incredible for extend volume of water resources in agricultural use. Highlighted an about new methodology - sub vector efficiency for define efficiency of water resources in base international studies. Sub- vector efficiency calculation on DEA model introduced. By current methodology have been analyzed and concluded correlation between water use and water efficiency in case of Samarkand province.
