Life Saving Irrigation under Drought Condition for Kharif Crops in Vindhyan Zone (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. The mean date of onset of effective monsoon (OEM) in Mirzapur district varies from 30 June to 9 July and there is moderate variation in the dates of onset of effective monsoon in the different years. The date of withdrawal of monsoon from 18th August to 8th September. The maximum irrigation requirement is observed during CDS for rice as 106.79mm at Jargo and sugarcane as 88.66mm during dry spell.
