Abstract
Energy analysis (input-output) of Maize production systems in Vikarabad district of Telangana State. Surveys conducted at the farms that cultivate Maize in Vikarabad district, in the 2021. Sixty farms that produce Maize were interviewed face to face. The results revealed that in Maize production systems total energy input was 40657.5 MJ/ha. The highest share of energy consumed was recorded for N fertilizer (73.69%) which is a nonrenewable resource. Output Energy was10892.7MJ/ha. Accordingly, energy efficiency (output input ratio) was 2.67, energy productivity calculated as 0.18 KgMJ-1 and specific energy was observed as 5.48MJKg-1, agrochemical energy ratio was 6.69% and energy intensiveness was 1.016. The energy use efficiency, energy productivity, specific energy, net energy of maize production systems were 2.67, 0.18 kg MJ-1, 5.48 MJ kg-1, and 68269.47 MJha-1 respectively.
