Crop Water Requirement under Selected Critical Dry Spell for Existing Crops in Mirzapur District, U.P

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.
