Surface and subsurface drainage technologies have found to be suitable for ameliorating these problems. The present study was conducted in Malaprabha and Ghataprabha irrigation command areas of North Karnataka, with an objective of identifying and analyzing the cost and returns of surface and subsurface drainage system and to study the impact of on-farm socio-economic condition of farmers. The results revealed that, the per hectare cost of adoption of surface drainage was Rs. 11,214 and Rs. 62,557 in case of subsurface drainage (PVC) and Rs. 47,628 in case of subsurface drainage (tile). The financial feasibility analysis showed in the case of surface drainage, NPV, BCR, IRR and PBP were Rs. 27,880, 2.97, 69 per cent and two years, respectively. Similarly in case the of subsurface drainage (PVC) NPV, BCR, IRR and PBP were Rs. 1,87,282, 4, 33 per cent and three years, respectively and in the case of subsurface drainage (tile) NPV, BCR, IRR and PBP were Rs.1,66,387, 4.72, 46 per cent and two years, respectively. Major problems in adoption of surface drainage and subsurface drainage were lack of knowledge, lack of cooperation among neighboring farmers. As the investment in adoption of surface drainage and subsurface drainage were found financially feasible, the farmers who wish to adopt these technologies may do so. Hence, the policy makers should encourage adoption of surface drainage and subsurface drainage by the farmers. Throw light on the subsidized rate of interest and scale of finance from financial institutions.Agricultural EconomicsThesis
