According to researchers at Pioneer Hi-Bred International, selection for kernel size is the least critical variable in corn growers' seed-related choices.
"The choice of kernel size must be kept in proper perspective with overall crop management goals and year-to-year fluctuations in seed availability," says Pioneer agronomy research scientist Tom Doerge. "Extensive field research by Pioneer and university scientists has found that kernel size has minimal effect on seed vigor, field emergence or final yield."
The researchers found that choosing crop genetics has the most impact on yield, followed by insect resistance and seed treatment selection.
Virtually all kernel sizes can be successfully planted with all planter types, but adjustments may be required in some cases.
