Corn kernel size has minimal impact on yield
Growers have a number of decisions to make prior to planting, but according to agronomy science researchers at Pioneer Hi-Bred International, Inc., seed size is the least critical.
Pioneer research concluded that the selection of corn kernel size has the
least impact on grain yield of any seed-related choice.
“Kernel size is a
decision that concerns some growers,” says Tom Doerge, Pioneer agronomy research
scientist. “However, the choice of kernel size must be kept in proper
perspective with overall crop management goals and year-to-year fluctuations in
seed availability. Extensive field research by Pioneer and university scientists
has found that kernel size has minimal effect on seed vigor, field emergence or
final yield.”
Choosing the best crop genetics has the highest impact on
corn yield – followed by insect resistance and seed treatment
selection.
