This study aimed to evaluate the Factors Affecting the Technical Efficiency of Agricultural Production Cooperatives in Golestan Province by using the data envelopment analysis method with a product-oriented approach and constant and variable returns to scale. The required data was obtained in the field and by completing a questionnaire and interviewing the managers of 36 agricultural production cooperatives active in Golestan province in 2020. To evaluate the technical efficiency, the Tobit regression model has also been used to investigate the factors affecting performance. The results show that the average technical efficiency of the surveyed cooperatives under the conditions of fixed returns and variable returns to the scale is almost equal; Therefore, agricultural production cooperatives in Golestan province are faced with a high level of scale efficiency. The results show that 69% of companies have fixed returns, 25% have descending returns and 6% have upward returns to the scale of production. The results of the study of factors affecting technical efficiency also indicate that the age variable has a negative and significant effect on performance. Also, the asset variable has a positive and significant effect on efficiency. The average values of technical and managerial efficiency show that it is possible to increase the output by 13% with the same amount of input. It is necessary to increase the efficiency of production cooperatives by supporting young people and using them in the field of production and providing the necessary funds for companies.

Since rural cooperatives play an important role in rural economic development, their performance evaluation is of great importance as well. Accordingly, the main objective of this research was to evaluate the technical efficiency of the rural cooperatives in Sistan and Baluchestan province of Iran, using the Fuzzy Data Envelopment Analysis (FDEA) technique and compare it with the classical DEA method. For this purpose, the required data of 52 rural cooperatives operating in the studied province in 2016.were collected and analyzed. The indicators used in this study included three inputs (i.e. capital, current costs, and number of vendors) and one output (i.e. profit). The study results showed that there were three efficient rural cooperatives identified in FDEA model while nine ones in the classical DEA method were found efficient; in addition, the mean efficiency score was evaluated 55 percent in the traditional DEA method while 32 percent in FDEA method, indicating low efficiency rates for the rural cooperatives in both methods though the FDEA method had a higher resolution. Therefore, as suggested by the study, comparing inefficient and efficient companies could provide a suitable platform for better utilization of resources so as to improve the technical efficiency of companies.

The purpose of this study is evaluate and compare technical efficiency of water users association by the approach of the stochastic frontier production function in Maragheh county. Accordingly, for scientific and real understanding of the performance of these associations, the efficiency of productive units is considered. In order to perform this study, the required data were collected through a questionnaire from 147 farmers of Maragheh County. To achieve the aim of this research, stochastic frontier production function was used in which farmers was a function of seed variables, nitrogen fertilizer, phosphate fertilizer and water. Results showed which average efficiency of producing in wheat fields of the sample is 78.9%. So on these farms with available inputs, there is an average of 21.1% chance to increasing the production. Based on the results, it is observed that in a stochastic frontier production function, nitrogen fertilizers,hosphate fertilizers, water and wheat seeds Variables have a significant effect on wheat production. Also Variables such as age, education, participation in extension courses, marriage and cultivating have a significant effect on technical efficiency. Between studied cases, Varjoy water users association, with average efficiency about 83.07%, has the highest technical efficiency. Therefore, participation in extension courses, adopting measures on land integration and benefiting from the experiences of successful Water Users Association will be an important step towards increasing the efficiency of the Water Users Association studied.

In this research the technical efficiency of the greenhouse units of strawberry production in Savojbolagh county has been studied and evaluated. In this study the data of 65 greenhouse units were gathered. The necessary information were about the characteristics of the greenhouse's manager, the operation quality of the greenhouse unit, the strawberry's  buy or sell quality, the location of the greenhouse, the situation of the inputs consumed, the case of the staff and the situation of the products. In order to estimate the technical efficiency, first we estimated two production functions in the forms of cobb-douglass (the representative of the inflexible functions) and translog (the representative of the flexible functions). The average technical efficiency for Alborz Province's strawberry producers was estimated about 0.79. The miminum and maximum technical efficiency of producers were estimated respectively 0.54 and 0.967 that show the difference between the maximum and the minimum technical efficiency among the producers.
