【 摘 要 】

Maize is the second largest crop grown in Nepal and is grown in all three geographic zones. The objective of this study is to analyse the energy input-output of maize production systems. The study is conducted in Sundarharaincha municipality of Morang district, Nepal, using direct questionnaires methods for the collection of primary data of varying landholding sizes farmers. The study revealed that total energy input and output for maize production system found about 10, 999.61 MJ/ha and 45, 501.52 MJ/ha, respectively, with the highest share by farmyard manure (FYM) about 50%. The energy use efficiency was found 4.14. Total CO2, N2O and CH4 emissions due to chemical inputs were found 163.24 kg/ha, 0.03 kg/ha and 0.33 kg/ha, respectively. The total Global warming potential was found 178.58 CO2 eq. per ha. The average cost of production were calculated USD 301.35/ha and profit USD 272.26/ha.
