Corn Yield Response to Tillage and Nitrogen Fertilizer Rate
Abstract
The research objective of this study was to measure corn yield response to nitrogen (N) rate in two tillage systems, tilled and no-till, in a soybean-corn rotation. Results were summarized across sites and years by analysis of the main effects and interaction of N rate and tillage system on corn yield, and through fitting N rate response equations. The across site-year response equations were used to determine economic optimum N rate (EONR) based on a 0.10 N fertilizer price-to-corn price ratio.
