During which time of year is wheat harvested in Iowa?

Wheat harvesting in Iowa typically occurs in late summer. This timing aligns with the growth cycle of wheat, which is generally planted in the fall and overwinters, or planted in early spring, maturing around mid-summer to early fall depending on the variety. By late summer, usually in July and August, the wheat has ripened and is ready to be harvested.

The other times listed do not correspond with the wheat harvest schedule in Iowa. Late spring is too early, as the wheat would still be growing. Early summer might also be premature for harvesting, depending on the specific variety and planting date. Late fall would be too late for harvest, as the crop would either be damaged by frost or already processed from the fields. Thus, late summer is the optimal time for wheat harvesting in this region.
