Abstract
The problems of water logging and salinization in irrigated commands have
led to low productivity, decline in crop production, increase in cost of production and
farm income. 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.
