The results showed that the input energy was 12105 MJ ha-1, of which the highest share was related to gasoline, nitrogen fertilizer and diesel fuel with 34.5, 29.7 and 13.75 percentages, respectively. The lowest input was belong to seed with 0.01%. The total greenhouse gas emissions in white radish production was 520.88 kg carbon dioxide per hectare, of which gasoline, manure, nitrogen fertilizer and diesel fuel constitute the highest input with 39.78, 33.11, 13.12 and 10.23 percent, respectively.
