Energy use pattern and energy efficiency of fully and partially mechanised rice production in West Godavari district of Andhra Pradesh state were estimated using energy input-output ratio analysis. The primary data was collected from 122 respondents during the year 2017-18. The indicators are net energy, energy use efficiency, specific energy, energy productivity. The energy equivalents were obtained from available literature by using the collected data. Analysis of data showed that average fertilizer had the highest share within the total energy input in both the systems followed by mechanization and irrigation in fully mechanized farms and irrigation and human labourer in partially mechanized farms. Energy use efficiency was calculated as 1.94 in fully mechanized farms and 1.45 in partially mechanized farms. The total energy input in rice production in fully mechanized farms (54,719 MJ/ha) was found to be less than partially mechanized (64,824 MJ/ha). The net energy from the fully mechanized farms (51,287.46 MJ/ha) was higher than that from the partially mechanized farms (29,178 MJ/ha). There were no significant changes regarding herbicides and irrigation in both the systems.
