Abstract:
Drought is an extended period when a region notes a
deficiency in its water supply whether surface or
underground water. Rainfall behaviour in drought
prone areas is erratic and uncertain. The adverse
effect of rainfall aberration on crop growth stage at
such deviation occur suitable manipulation in crop
management practices are needed to minimize such
adverse effects of abnormal rainfall behaviour. It is
essentially make provision for supplemental
irrigation during critical dry spell periods by creating
additional ground water storage wherever necessary
and store the rainfall water when the heavy rainfall
takes place and minimize the wastage of water. It is
also essential to make provisions for life saving
irrigation during these critical dry spell periods by
creating additional storage wherever necessary. The
water requirement of selected crops have been
estimated for three critical dry spell duration and
optimize yield.
