Abstract
The objective of this project was to measure corn yield response to fertilizer nitrogen (N) application timing (spring pre-plant or at-planting vs. split/side-dress) across multiple N rates (0 to 250 lb total-N/acre). Results were determined through fitting yield response to N-rate regression equations and calculation of economic optimum nitrogen rate (EONR) based on a 0.10 N fertilizer price-to-corn price ratio.
