Application of appropriate agricultural operations is a strategy to reduce energy consumption and greenhouse gas emissions from agricultural productions process. In this study, fuel consumption and greenhouse gases emissions values for each farm operation was evaluated in Gorgan and Ali-Abad Katol to soybean product. All activities and production processes about operations were monitored and recorded in 26 fields. Results showed that the time required to perform various operations took between 0.2-3.9 hours per hectare. Fuel consumption values for various operations were between 3-38.1 liters per hectare as the highest fuel consumption was observed to do 3-bottom chisel plow. Energy consumption of operations was between 138.9-1707 mega joules per hectare. In the case of greenhouse gases emissions from different operations estimated from 12.5 to 170.9 kilogram carbon dioxide equivalent per hectare. By using this study's results, it is possible to compare different scenarios of soybean production in terms of energy consumption and greenhouse gases emissions and select the best scenario(s) to product this crop.
