Abstract
waterlogging was evaluated for viability using discounted eashllow techniques
such as Benefit-Cost Ratio, Net Present Worth and Internal Rate of Return. The
subsurface drainage was found to be technically feasible and financially viable
as demonstrated by calculated IRR, BCR, and NPW. They opined that in the
absence of an appropriate organizational setup, the technology could not be
widely adopted.
Ajorc and Singh (1997) in their study on reclamation of alkali soils in
U.P. identified constraints in adoption of land reclamation technology. Majority
of the farmers were not aware of the full package of reclamation technology.
Lack of irrigation facilities, fragmented holdings, inadequate supply of gypsum
and fear of more recovery on subsidy were major constraints.
From the above studies, it can be abstracted that reclamation technology
adopted individually by the farmers and reclamation programmes implemented
by the government had positive impact on productivity, income and
employment. There was substantial increase in gross cropped area. The
technology was economically worthwhile as demonstrated by the benefit cost
analysis. Most of these studies addressed problems relating to alkali soils. Soil
degradation due to salinity and waterlogging have not been dealt adequately
