Management Strategies for Drought Stress in Maize (Zea Mays L.)

Drought is considered as the most important devastating abiotic stress as it has rendered large area of agricultural land unproductive around the globe. The frequent occurrence of droughts and increased water shortage in agricultural ecosystems resulted in yield losses in many crops. Maize is one of the leading cereal crops in the world, but it is sensitive to drought. Hence, presence of maize genotypes tolerant to drought can stabilize and increases the grain yield of maize. Therefore, developing drought tolerant cultivars is a challenge for breeders. There are two ways to mitigate drought stress in maize production, either by developing and using drought tolerant cultivars or by developing and practicing improved drought mitigation strategies viz., exogenous application of growth regulators and nutrient management etc.
