The yield potential of corn is perhaps most at risk to drought and heat stress during pollination and grain fill. In many situations, drought stress is compounded by heat stress as these two stress components commonly occur simultaneously.
Drought impacts corn during pollination in two ways. Silk growth rate is slowed and photosynthesis is reduced. Heat can significantly impact silk and tassel synchrony.
