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. Raziskava energetske učinkovitosti pridelave koruze je bila opravljena v provinci Khuzestan, okrožja Izeh v Iranu. Podatki za raziskavo so bili pridobljeni z ustnim anketiranjem 30 pridelovalcev koruze v letu 2011. Rezultati so pokazali, da je bil celokupen vnos energije v ta pridelovalni sistem 34,640 MJ.ha-1. Največji delež porabljene energije odpade na dušikova gnojila (20,80 %), kar predstavlja neobnovljivi vir. Izplen energije je znašal 102, 973 MJ.ha-1. Učinkovitost izrabe energije (vnos/iznos) je bila 2,97, izračunana energetska produktivnost je bila 0,20 kg.MJ-1, neto energija pridelka je znašala 68,333 MJ.Kg-1. Agrokemijsko energijsko razmerje je bilo 48,97 %, kar predstavlja dokaj velik vnos energije v tem agro-ekosistemu.
