Abstract
A study was conducted to evaluate the effects of potassium (K) fertilization and new corn hybrids resistant to rootworm on grain yield and K uptake in continuous corn. New corn hybrids may increase yield and change K uptake or fertilization needs through improved traits that increase yield and root efficiency. Therefore, the study was planned to test this hypothesis by comparing continuous corn yield and response to K fertilization of hybrids with and without the rootworm resistant trait.
