Occurrence of drought phenomenon in recent years makes the need to careful planning for efficient use of existing water resources in agricultural consumptions essential. The aim of this study was to determine the technical and economical optimal level of water use in agriculture sector. Required statistics and data were collected through completing 155 questionnaires by farmers under coverage of traditional irrigation system in Kohgiluyeh and Boyer-Ahmad province using the simple random sampling method from the tables relevant to all beneficiaries of the traditional irrigation system of the district water organization related to counties of Boyer-Ahmad, Gachsaran and Dehdasht in the year 2009/2010. Demand functions for selected products were extracted by profits maximizing method using quadratic production function. The results of the study showed that technical optimum level of water use in farms of wheat, barley and canola, respectively, were as 6786, 4839 and 8277.31 cubic meters that these volumes of water are necessary for maximizing the production rate of each of these products. Economically optimal amount of water to maximize the producers’ profits of wheat, barley and canola, respectively, were as 6718.706, 4808.73, and 8277.14 cubic meters of water; meaning, this amount of water is required to maximize the profits of the producers of mentioned crops. Comparing the technical and economic optimum levels of water use on selected farms showed that the two values are very close together. The closeness of technical and economic optimum levels of water use is due to the very low price of water. | | Keywords : | | |
