To evaluate different nitrogen (N) rates in 30 in. rows, applied to multiple populations, to determine the Economic Optimum Nitrogen Rate (EONR) and Economic Optimum Seeding Rate (EOSR) combination.

2016 Indiana Corn Population vs. Nitrogen Rate Study - 30 in. Rows

In 2016, the EOSR was 34,000 plants/A. in both hybrids, regardless of the hybrid's genetic response to population.

The EONR was higher in BECK 5829A4brand, the hybrid that is more N efficient. We saw increased yields with each increase in N rate with XL® 5665AMX™*brand, the less efficient user of N, although it was not economical.
