Sponsored: Greatest ROI seen at 32,000 seeds/A. coupled with 185 lbs./A. of Nitrogen

This one-year evaluation set out to study different nitrogen (N) rates, applied to multiple populations, in order to determine if N rates should vary based off of planted population. 

The assumption can be made that if the planted population on corn increases, we need to increase the N rates to accommodate the additional plants. However, we are not finding that to be the case. With this study, Beck's Practical Farm Research (PFR)® found that the greatest return on investment (ROI) came at 32,000 seeds/A. coupled with 185 lbs./A. of N. As the population was incrased, adding N did not increase yield. 

This study would indicate that the greatest ROI from N is not related to population. 

As genetics improve and are better able to handle higher populations for maximum yield, we will continue to evaluate the N/population relationship in the future.
