Results from the first 2 years of this study to determine appropriate application rates for sweet corn processing wastes indicate that land application for management of waste materials is a feasible approach. Agronomic responses of field corn to applications of up to 200 tons/acre of sweet corn residue were positive. Plant emergence, plant height, dry matter yields, and grain yields were increased by increasing rates of residue application. Yield responses to residue rate occurred even where there was no response to fertilizer N, suggesting that the residue additions provide beneficial effects other than contributing N. High soil N contributions at the experimental site prevented yield response to added N.
