Production of maize in Northern Karnataka: decomposition analysis approach

Abstract

The present study was conducted in two districts of Northern Karnataka, namely, Belagavi and Vijayapur. The required data was collected from 60 farmers practicing sprinkler system and 60 farmers practicing the conventional method of irrigation in the cultivation of maize. The data was analyzed using the output decomposition model developed by Bisaliah (1977). The study revealed that the adopters of sprinkler irrigation technology produced 21.79 percent higher income than the conventional method of irrigation. The increase in the income was further decomposed into different sources of change, such as the adoption of sprinkler irrigation technology and changed input levels. The sprinkler irrigation technology alone contributed 43.77 percent increase in income, while the contribution of change in input levels was found to be negative (-21.99 percent).
