Water Demand in Maize Is Projected to Decrease under Changing Climate in India

Crop stage-specific information on the impacts of projected climate change crop and irrigation water requirements are essential for improving productivity. This study investigated possible implications phenology, effective rainfall (Peff), (CWR) (IWR) maize in eight locations India. CWR, Peff IWR were estimated seven stages viz., emergence, 5th leaf stage, tasseling, silking, milking, dough maturity during baseline (1980–2009) near-century (2022–39) using data derived from a subset 29 general circulation models. The results indicated that mean seasonal maximum temperature, minimum temperature to increase all locations. Hence, total duration (3–7 days), CWR (8–69 mm) (1–54 decrease. could identify specific which greatest reduction duration, would occur. Such will be immense help farmers varietal improvement programs regions near future.
