  Abstract


Water Resources and Agriculture in north Bihar is base of economy. Irrigation scheduling many researchers have attempted to find out the lower limit of available water in the assumed shallow root-zones of crops at which the irrigation must be applied to avoid yield reduction. Though this approach is still prevalent, but it suffers from a few serious drawbacks. Firstly, the assumption of a fixed root-zone runs counter to the dynamic and ever deepening character of crop roots during the greater part of the growing period. Secondly, the periodical determinations of root-growth and soil-water depletion are beyond the know-how and means of the common farmers. Whatever short comings are in this approach, it helped in fixing irrigation schedule earlier. The sowing time available water storage achieved through heavy pre-sowing irrigation which is a common practice is an insurance against the irrigation-deficits during the growing period. The irrigation depth for post-sowing watering depends upon the water storage deficit of the root-zone which is determined by the time-interval between irrigation and ET demand.
