Field corn is every variety of maize that is not grown primarily for consumption as human food in the form of fresh kernels in the United States. In contrast, sweet corn is grown primary as an edible crop. Popcorn, although it is not grown for human consumption in the form of fresh kernels, is not considered to be field corn. More than 98% of corn-growing land in the U.S. is in use for field-corn production.
Principal field corn varieties are:
- Dent corn
- Flint corn
- Flour corn , including blue corn (Zea mays amylacea)
- Waxy corn
