University of Tehran Iranian Journal of Agricultural Economics and Development Research 2008-4838 48 3 2017 09 23 Analysis Factors Affecting Date Production Efficiency in Bam County: With DEA Approach Analysis Factors Affecting Date Production Efficiency in Bam County: With DEA Approach 507 518 63969 10.22059/ijaedr.2017.63969 FA Journal Article 2015 05 24 Bam region is one of the main regions for Mazafati Date production in Iran. Because of limitation of Date production inputs in Bam region application of optimum production management in input utilization is necessary. The main objective of this study was to estimate the technical, scale, allocative and economic efficiencies. The efficiencies were estimated using data envelopment analysis (DEA) technique. The statistical population of this study consisted 1240 Date producers of Bam county, in which 142 of them were chosen as statistical sample by applying Stratified Random Sampling and Cochran formula. The data were collected by questionnaire that designed with open question. Face and content validity was approved by a panel of experts. Research results revealed that mean technical, scale, allocative and economic efficiency scores of the sample orchards were 61.15, 66.2, 46.14 and 28.22 percent, respectively. Findings revealed that the farmers were inefficient in the use of all the resources; and all producing inputs were used higher than optimum consumed amount and the most discrepancy of consumption respectively were in animal fertilizer, chemical fertilizer, machinery use and water use. An econometric analysis based on Tobit Regression models indicated that age of farm operator, years of schooling, number of contacts with extension agents and orchard capital had significant impact on of technical efficiency.
