This paper studies the energy balance between the input and the output per unit area for garlic in Hamedan province of Iran. In this study, data were collected by administering a questionnaire in face-to-face interviews. Results showed that the highest share of energy consumption belongs to chemical fertilizers (41.7%) followed by diesel (13.94%). The results indicated that a total energy input of 40307.89 MJ ha−1 was consumed for garlic production. The energy productivity and net energy value were estimated as 0.416 kg MJ−1 and −13477.82 MJ ha−1, respectively. The ratio of energy outputs to energy inputs was approximately 0.66. Results indicated that direct, indirect, renewable and non-renewable energies were (28.14%), (71.85%), (36.73%) and (63.26%), respectively. Highest shares of expenses were found to be 45% and 19% for human labor and hired machineries, respectively. Cost analysis revealed …
