I was out this afternoon looking at some badly stressed corn. It was easy to see how pollination was affected by the drought.
My rough estimate would be 25% of the kernels on this ear were not fertilized. That does not equate with 25% yield loss because if soil moisture levels improve the plant will put more weight into the fertilized kernels. On the other hand if it gets drier, the yield loss will be worse.
There is a good video from the Pioneer website describing the impact of severe drought on both corn and soybeans.
