Sponsored: 2015 Economic Optimum 225 lb./A. Nitrogen
This seven-year study was designed to find the economic optimum nitrogen rate (EONR), which is the rate of nitrogen (N) that maximizes profitability.
In 2015, seven N rates, ranging from 0 to 250 lb./A., were evaluated in a corn after corn crop rotation. All entries, with the exception of the 0 lb./A. control, received a split application of UAN as a 2x2 application at planting, followed by a sidedress application of UAN at the V3 growth stage to meet the total amount of N for each treatment.
The corn after corn N rate study was completed at four of Beck's Practical Farm Research (PFR)® sites in 2015. The results were higher than the seven-year multi-location EONR.
Beck's Hybrids PFR program conducts more than 100 different studies across multiple locations (700+ acres) to learn how different management practices and new technologies perform in field environments. Simply put, it is research focused with the farmer in mind.
