Online published on 23 December, 2016. Abstract The present study was conducted in four districts of Northern Karnataka namely, Belagavi, Vijayapura, Bidar and Kalaburgi. The required data was collected from 120 farmers practicing micro irrigation system (drip irrigation) and 120 farmers practicing conventional method of irrigation in cultivation of sugarcane. The data was analysed using the output decomposition model developed by Bisaliah (1977). The study revealed that the adopters of drip irrigation technology produced 25.31 per cent higher income than conventional method of irrigation. The increase in the income was further decomposed into different sources of change such as adoption of drip irrigation technology and changed input levels. The drip irrigation technology alone could contribute 44.83 per cent increase in income, while the contribution of change in input levels was found to be negative (−19.53 per cent). Amongst the various inputs, seed (−2.40%), farm yard manure (−2.00%), fertiliser (−3.95%), human labour (−16.95%), bullock and machine labour (−0.84%) and plant protection chemicals (−1.35%) contributed negatively to the income.
