Abstract
The aim of this study was to determine the energy requirement for a semi-mechanized production system of groundnut in Kiashahr region, north of Iran. Data were gathered from 62 groundnut farms using a face to face questionnaire method. Results showed that the energy input of the diesel fuel had the highest share (43.51%) in the total energy inputs followed by the chemical fertilizers (29.11%). Total energy input was found to be 20164.36 MJ/ha and total output energy was determined as 79252.02 MJ/ha. Energy output-input ratio, specific energy, energy productivity, and net energy gain were computed as 3.93, 4.74 MJ/kg, 0.212 kg/MJ, and 59087.66 MJ/ha, respectively. Renewable and non-renewable energy were 19.27% and 80.73% in the total input energy, respectively. The direct and indirect energy shares for semi-mechanized groundnut production also were found to be 53.80% and 46.20% MJ/ha of the total input energy, respectively.
