Kernels set early in season

Encyclopedia Article

Want to increase corn yield potential? Aim for increasing kernel numbers! Yield is a function of kernel number and kernel weight. The number of kernels per acre will vary based on other components including plants per acre, ears per plant, and kernels per ear. The number of ears per plant is primarily influenced by hybrid. Most hybrids grown in Iowa have one dominant ear, although some "prolific" hybrids are available that produce more than one ear per plant at normal seeding rates.
