Feasibility of cement nala bund in reference to precipitation deficit and crop yield

Average precipitation deficit for Wan river basin was estimated as 81.02 ha-cm. Total water that could be harnessed with six CNBs along Wan river reach is estimated as1,09,262 m3. The increase in yield of cotton and pigeon pea crop in basin area due to protective irrigation was estimated as 50 q and 468.2 q respectively. In general, constructions of CNBs were assessed as economically viable in terms of increased yield.
