Resumo: | Grape is one of the most important fruits that has a long history of cultivation and production in our country. Effective use of energy in agriculture is one of the main reasons for the emergence of sustainable agriculture. It reduces environmental problems and pollution, prevents the destruction of natural resources and preserves fossil fuels. Energy analysis is also essential for the proper management of scarce resources to improve agricultural production and thereby identify efficient and economical production activities. In this research, determination and evaluation the energy consumption of grape production in Eyvan county (Ilam province). In the present study, the required data were collected from the presence method and a questionnaire was collected from the grape producers in the county of Eyvan in 2019. The number of questionnaires was calculated using Cochran's equation and was 177. According to the collected data, the results showed that the weighted average of energy efficiency, energy efficiency, net energy and energy in the studied gardens was 5.44, 0.67 Kg mJ-1 and 126049.60 MJ ha-1 and 1.48 MJ kg-1. The share of direct, indirect, renewable and non-renewable energy of total energy consumption was calculated as 54.68, 45.32, 22.47 and 77.53%, respectively. ‌‌‌ The Results of sensitivity analysis of energy inputs to investigate the effect of increasing or decreasing inputs on product performance showed that 56.63% of total production costs were related to variable costs and 43.37% of total production costs related to fixed costs. The total amount of input and output energy was 28364.25 and 154413.86 MJ.ha-1, respectively. The net profit (net profit) for canola was 454963010 Rials, which shows that the production of canola in the region has economic justification.
