This study was carried out in Khuzestan province in Iran and aim of investigation was energy analysis (input-output) of maize production systems in Izeh County of Iran. Data were collected from 30 maize farms by using a face to face questionnaire method in 2011. The results revealed that in maize production systems total energy input was 34.640 MJ.ha-1. The highest share of energy consumed was recorded for N fertilizer (20.80%) which is a nonrenewable resource. Output energy was 102.973 MJ.ha-1. Accordingly, energy use efficiency (output-input ratio) was 2.97, energy productivity calculated as 0.20 kg.MJ-1 and net energy was observed as 68.333 MJ.Kg-1. Also, agrochemical energy ratio was 48.97% which is high ratio of input energy in this agro ecosystems.
