Abstract

Dryland agriculture is entirely reliant on the monsoonal rainfall for its crop sensation. Pearl millet crop cultivation in a rainfed region like Madurai district Tamil Nadu became remunerative task, where the major rainfall contribution is from North-East monsoon. The influence of seasonal rainfall variability on pearl millet was quantified through correlating the inter-seasonal rainfall deviation with pearl millet productivity using the 30 years (1990-2019) rainfall and simulated pearl millet productivity data. Results indicated that pearl millet productivity had the relationship with seasonal rainfall by 46 percent. The research revealed that pearl millet crop yield dropped in nine out of 12 dry rainfall years and excess rainfall years also reduced the yield of pearl millet crop. It may well be implicit from the results that low and high rainfall years adversely affect the yield of pearl millet crop.
