Abstract

A three-year study was conducted at this farm to evaluate the effects of potassium fertilization and new corn hybrids resistant to rootworm on grain yield and potassium uptake in continuous corn. New corn hybrids may increase yield and change potassium (K) uptake or fertilization needs through improved traits that increase yield and root efficiency. Therefore, this 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.
