Corn Ear Types
Ear types are defined as fixed, flex, or something in between. A hybrid with a fixed ear size means it makes the same size ear regardless of plant populations, while a hybrid designated as a flex type hybrid makes either longer and/or girthier ears when plant populations are decreased. A flex ear hybrid is desirable where plant populations below the desired level. A fixed ear hybrid would be desirable when planted at their optimal plant population on highly productive soils. Fixed ear hybrids, with their tolerance to high plant populations, tend to be the highest yielding. Most fixed ear hybrids tend to be shorter statured. Thus, when planting them thicker, they will usually grow taller.
