In 2020, this research has been devoted to the determination of energy indicators and economic analysis in the vineyards of Qazvin province, after calculating the amount of energy consumption and economic indicators, optimization was done using the method of data envelopment analysis. According to the results, the energy ratio of grapes was estimated as 9.66 and 11.26 in traditional and semi-mechanized methods, respectively. Also, the economic results showed that the net profit of one ton of grapes in the traditional and semi-mechanized method was 2609.77 and 2995.22 dollars per hectare, respectively. The data coverage analysis method showed that the average scores of technical efficiency, pure technical efficiency, and scale efficiency for traditional grape production are 0.90, 0.95, and 0.94 respectively. Also, the average scores of technical efficiency, pure technical efficiency, and scale efficiency for semi-mechanized grape production are 0.91, 0.97, and 0.93, respectively. Based on the results of optimal consumption, it has led to a 25.19% reduction in the energy consumption of traditional production and a 24.78% reduction in the energy consumption of semi-mechanized grape production. According to the results, the high energy consumption of chemical fertilizers should be directed towards organic agriculture and less use of chemical fertilizers and pesticides as as possible. Also, it is suggested that optimal energy consumption and saving at the level of farmers should be advertised and promoted by the relevant bodies.
