Current conventional agricultural systems using intensive energy have to be revitalized through new integrated approaches relying on renewable energy resources, which can allow farmers to stop dependence on fossil resources. The aim of this study was determining the amount of input–output energy used in onion (Allium cepa L.) production in Khorasan Razavi province. For this purpose, the data was collected from 55 onion farm workers in Khorasan Razavi. Inquiries were conducted in face-to-face interviews in April-May 2011. Farm workers were selected based on random sampling method. The results indicated that total energy input was 98479 MJ.ha-1. The share of electricity and nitrogen fertilizer was 50.9 and 14.7%, respectively out of total energy input. The average onion yield under normal conditions was 73227 kg.ha-1 on irrigated farms. The net energy and energy productivity values were estimated to be 18684 MJ.ha-1 and 0.74 kg.MJ-1, respectively, and the ratio of energy output to energy input was found to be 1.19. This indicated an intensive use of input in onion production, which is not parallel to the increase in the final yield. Approximately 77.3% of the total energy input used in onion production was non-renewable (machinery, diesel, fertilizers, chemicals and electricity) and only 22.7% was renewable energy form (human labor, manure, water for irrigation, seeds). Cost analysis revealed that total cost of onion production for one hectare was 79262908 Rials. Benefit–cost ratio was calculated as 1.65. Although energy efficiency of onion production in Khorasan Razavi province is low, it is economically justified.
