چکیده:
omegranate is one of the most important economic products in the agricultural sector in Sistan region. This region due to dry weather, very low rainfall and frequent droughts and lack of resources for agriculture faces many problems. Hence, one way to increase agricultural production is to increase efficiency, So that it can help the economy of the region. In this regard, in this study, the effectiveness of pomegranate gardens in Sistan region is considered as one of the main product. For modeling and analyzing information was used from Eviews and Frontier softwares. In this study SFA method was used for data analysis. Data has been collected in Zabol, Zahak and Hirmand from 150 farmers in 2016-2017 year. The results show the technical efficiency the city of Zabol, Hirmand and Zahak are respectively 60, 55 and 67 percent. Also for the city of Zabol, age, experience, household size, number and size of garden plots for city and for city of Zahak, experience, size of household and garden, for city of Hirmand, experience are significant impact on technical efficiency. Finally, with regard to the percentage of responding farmers, will provide suggestions for improving them.

The third hypothesis suggests that the inefficiency effects model variables such as farmer's age, education, experience, size of household, attending promotional activities of pomegranate grown, the gardens, the trees, the number of units in garden plots on technical efficiency levels were not affected in this study.
Table 2: Estimate the Results of the Stochastic Frontier Model and Technical Inefficiency Pomegranate Hirmand City Zahak City Zabol City {مراجعه شود به فایل جدول الحاقی} Source: Research Finding, *, **, *** Show respectively Significant of the 10, 5 and 1 percent.
In general, the coefficients being significant for the Zabol city, according to the stochastic frontier model, the factors, frequency of irrigation and cultivation in city of Hirmand and Zahak has increased the most effective and positive impact on pomegranate production.
The results indicate that variables of the farmer's age, household size, number and size of garden plots with pomegranate production, have significant relationship with inefficiency in the city of Zabol.
As the age variable was explained by increasing age, experience, and squinty increase the technical efficiency has increased: Table (2) to examine these factors are addressed Farmer age (Z1): effect coefficient of age is negative and significant on the inefficiency in the city of Zabol, while there is the lack inefficiency of Hirmand and Zahak any significant effect.
Between variables, education and advocacy attending technical and relationship with economic efficiency, there was no significant, so should be the level of quality and quantity of classroom science to promote agriculture and farmers, adequate and proper supervision.
