Evaluating the Environmental Efficiency of Cotton Workers in the country

Cotton has economic and commercial importance, due to the various uses in today's world. It is also one of the most important oily plants in the world, and its cultivation is increasing in countrys. In recent years the government has special attention, considering that this product is the raw material of textile industry; therefore, the evaluation of this product is a very important factor and has an impact on increasing its production and performance without the need for additional costs. In the present study, technical, allocation, economic, and technical measures were performed with two standard and combined methods, at two fixed and variable levels, in order to determine the water use efficiency and its environmental performance in the producing provinces of this product. The statistical data of this study were extracted from the Agricultural Jihad in the years 2015-2014. The average economic efficiency, variable in relation to scale in both standard and environmental methods is respectively 0.81 and 0.78% respectively. In this study, after solving the institutionalization overlay model, the results were compared to the standard scale for comparing both standard and environmental methods at constant and constant levels. Based on these results, the provinces that are well-known efficient in the standard method are also relatively efficient by the specific environmental method. But for non-efficient provinces, the estimated value of the special compilation method is lower than the standard values. It is advisable to help raise the productivity of cotton farmers through their participation in extension classes, the improvement of irrigation practices and the use of green water (sewage treatment).
