 If there are fields that are experiencing stress now, we may see a reduction in ovule number. But again, depending on how well pollination and early grain fill proceeds, it may or may not have an effect on final kernel number at harvest. Nielsen's point is that a reduction in ovule number during the ear size determination period does not automatically translate to lower yield, particularly if growing conditions during pollination and early grain fill stages are favorable for kernel set. This is the American Ag Network.
