There is the acreage portion to that question and there is the agronomic part to that question. From the agronomic side, what does abnormally dry in central and northern IA do to crops without abnormally high heat. Good to great crops can be grown in those conditions in that locale. Now where they have moderate drought the crop obviously has been hurt. The question is to what degree. If that 20% of IA has corn yields that are down 50(that is actually a very big decline), but the other counties are up 12.5bu it’s a wash. And if instead of 50 it’s down 25 and the rest of the state is up say 10bu it’s a record.
It would take some time to go through the records, but if IA is like the US state averages, tying records in all counties at the same time is likely much higher than the current state record. That is to say the record state yield year still had stragglers that didn’t see near their best years.
