Conclusion
An integrated water resources management approach comprising in-situ water conservation
measures including both inter terrace and terrace level practices, harvesting of excess water in
ponds and groundwater recharging, improved crop varieties and improved inter-cropping
systems produce more food and income per unit of rainfall.

Rainfed agriculture is the main feature of Jharkhand state and rice is the most important crop
in major part of eastern India comprising Assam, West Bengal, Jharkhand, Orissa, Chhattisgarh
and eastern UP during the kharif and growing second crops in rice - fallow after rice harvesting
during rabi, soil moisture availability is the main limiting factor for growing second crops in
rainfed rice fallows of eastern India (Kar et al., 2006). In view of rapid increase in population
and day by day decrease in water resources and to fulfill the increasing pulse demand and
decreasing pulse production; sustainable water management practices and estimation of water
requirement will help to increase productivity of pulses, water productivity, water use
efficiency and area of pulses under irrigation. Improving water use efficiency in agriculture
will require an increase in crop water productivity i.e., an increase in marketable crop yield per
unit of water used by plant and reduction in water losses from the crop root zone. Among the
sustainable water management practices, scheduling irrigation based on evaporation is one of
the best methods in semi-arid condition where annual rainfall is low. Crop water requirement
is the total water needed for evapotranspiration, from planting to harvest for a given crop in a
