The present study was conducted in two districts of Northern Karnataka namely, Bidar and Kalaburgi. The required data was collected from 60 farmers practicing sprinkler system and 60 farmers practicing conventional method of irrigation in cultivation of rabi sorghum. The data was analysed using the output decomposition model developed by Bisaliah (1977). The study revealed that the adopters of sprinkler irrigation technology produced 35.08 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 sprinkler irrigation technology and changed input levels. The sprinkler irrigation technology alone contributed 50.24 per cent increase in income, while the contribution of change in input levels was found to be negative (-15.15 per cent).
