In India, variation in crop yield is occurs due to wide variation in energy inputs, agro-climatic conditions, and different resources used. Keeping this in view, a study has been carried out to find the energy efficiency of micro irrigation. The field experiment was carried out with drip method of irrigation (DMI) and conventional method of irrigation (CMI) at 100 per cent ET at two locations in Jalgaon district of Maharashtra during 2009-'10. The irrigation water requirement of the banana crop was noticed minimum in DMI compared to CMI treatment indicating 35.14 and 29.24 per cent water saving and 38.96 and 33.41 per cent electricity saving in experimental and farmer's fields, respectively. Early flowering and harvesting was noticed with reductionin growth period in DMI against CMI. The banana yields in DMI were (72.6 and 67.4 t·ha-1) higher against CMI (59.1 and 52.5 t·ha-1) under experimental and farmer's fields, respectively. In DMI about 32.70 and 29.99 per cent input energy savings and 19.73 and 14.09 per cent increase in output energy were noticed against CMI. Also, the higher energy efficiency of 13.5 and 12 was noticed in DMI as compared to CMI (7.6 and 7.4). In both the fields, 17.01 and 20.36 per cent higher BC ratios were recorded in DMI (2.27 and 2.01) over CMI (1.94 and 1.67). The present study reveals that drip irrigation has a definite role in minimizing the energy use in terms of water and electricity as well as reducing the impacts of climate change in Indian agriculture.
