Data envelopment analysis method usage for efficiency determination of pistachio growers in Sirjan

Iran isone of the main pistachiogrowersinthe world. Kerman province is the largest grower of pistachio and Sirjan is one of the most important pistachio production areas of Kerman province. It is important to the study of efficiency status of pistachio growers and improvetheir efficiency and optimum use of resources in the production. The purpose of this study was to determinationtechnical efficiency,allocative efficiency, economic efficiency, managerial efficiency and scale efficiency of pistachio growers. 197 pistachio farmers were randomly selected as sampls. Necessary information getting from the questionnaires was filled out for the years 2011 and 2012. Efficiency of pistachio growers was calculated using Data Envelopment Analysis Method (DEA). Theresults show the 47% average technical efficiency, 69% average managerial efficiency, 67% average scale efficiency, 24% average allocative efficiency and 12 average economic efficiency. With education and agricultural extension in order tothe optimal use of inputs, reducing the consumption of inputs can increase the efficiency.
