## In detail

Maize is very sensitive to water during flowering, when the tassel and silks emerge; drought at this stage harms pollination and kernel set. Water stress during grain fill can leave kernels small.

Drought-tolerant varieties come through this stress with smaller losses, but no variety reaches its full yield potential without enough water. Tolerance is not a substitute for irrigation and good soil management.

## Why does it matter when choosing seed?

Where irrigation is limited or summer drought risk is high, varieties whose sheets state drought tolerance help reduce yield risk.
