The agricultural sector heavily relies on energy to meet the ever-increasing food demands of the growing population of the planet and to provide sufficient and proper nutrients. Assessment of energy-use patterns in the agricultural sector seems to be critical due to the limited natural resources and the adverse impacts of improper utilization of various energy resources on human health and the environment. Therefore, this study aims to investigate the management indicators affecting greenhouse efficiency. Efficiency is the production of goods with higher quality in the shortest possible time, which is categorized into three types: technical, allocative, and economical. Technical efficiency can determine the ability to produce the maximum possible output from a certain bundle of inputs. In this study, the Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA) were used to determine the technical efficiency of greenhouses, and Eviews, SPSS, and Frontier software were also used for data analysis. In the present study with a sample of ۳۸ greenhouses among the greenhouses of Savojbolagh County, it was concluded that the production increased by ۱۴.۵%, ۴۱.۱%, and ۱.۵%, with ۱% more use of chemical fertilizers, pesticides, area, and irrigation, respectively; also factors such as education and applying modern knowledge affect the technical efficiency of greenhouses.
