DECOMPOSITION ANALYSIS OF INCOME DIFFERENCE BETWEEN FURROW AND BORDER STRIP METHOD OF IRRIGATION IN CULTIVATION OF CHICKPEA IN MALAPRABHA COMMAND AREA OF KARNATAKA

摘要

The present study was conducted in the Malaprabha command area as many scientific irrigation methods were implemented by the RKVY project. The required data were collected from the 35 farmers each practising border strip method of irrigation (scientific) and furrow method of irrigation (traditional) in the cultivation of chickpea. The data was analysed using the output decomposition model developed by Bisaliah (1977). The study revealed that the adopters of border strip inrigation technology produced22.13 per cent higher income than furrow irrigation. The increase in the income was further decomposed into different sources of change such as adoption of border strip irrigation technology and changed input levels. The border strip irrigation technology alone could contribute 13.80 per cent increase in income, while the contribution of change in input levels was also found to be positive (8.33 per cent). Amongst the various inputs, fertilizers (-2.25 per cent) and cost of irrigation (-1.60 per cent)contributed negatively whereas seed (0.03), human labour (6.10 per cent), bullock and machine labour (5.96 per cent) and FYM (0.07 per cent) contributed positively to the income.
