Abstract
The aim of this study was to determine the input–output energy consumption in different levels of tomato production. The data used in the study were obtained from 140 tomato growers in different villages of Marand Township by using a face to face questionnaire. The results showed that the amount of energy consumed in tomato production was 65.2 GJha-1 which about 51% of this was generated by chemical fertilizers and 21% from water for irrigation. Energy ratio and productivity was found to be 0.59 and 0.74 KgMJ-1, respectively. About 30.9% of the total energy inputs were renewable while about 69.1% were non-renewable. The results showed that medium farms were more successful in energy use efficiency and productivity, too. It was concluded that energy use management by using livestock manure, proper using of machines and reform culture at farm level could be improved to give more efficient use of energy in region.
