This research examines the energy use patterns and greenhouse gas emission of sugar beet farms in Hossein abad village of Shirvan city, in 2017-18. Data were collected by using a face-to-face questionnaire. Farms were selected with a random sampling method. In this study, the inputs in the calculation of energy use include: human labor, machinery, diesel fuel, chemical fertilizers, farmyard manure, biocides, electricity, water and the output in the calculation of total output energy include plant yield. The results indicated that total energy inputs were 66879.92 MJ ha-1and outputs 1310572.50 MJ ha-1. Of the total energy consumption in sugar beet production, 38.39% is related to the use of chemical fertilizers, 25.95% is related to diesel and 12.69% is related to electricity. Energy use efficiency of 19.59 and energy productivity of 0.72 kg MJ ha-1 were recorded. Chemicals, fuel and electricity played the largest role among energy inputs in beet farms. CO2, N2O and CH4 emissions were 2463.26, 21.02 and 3.26 kg ha-1, respectively. And the amount of global warming potential of these gases was calculated as 9048.85 CO2eq ha-1, of which 0.76% was related to CH4, 27.22% was related to CO2 and 72.02% was related to N2O.
