The purpose of this study is to compare 15 in. and 30 in. rows, at various planting populations, in an attempt to determine the Economic Optimum Seeding Rate (EOSR) for each row width.

2017 Ohio Corn Row Width and Population Study - 15 in. Rows vs. 30 in. Rows

When looking at the two hybrids tested in this study and their averages, we noticed that the 15 in. rows were consistently more profitable. The greater net return with this row width occurred regardless of the planted population. While the distance between rows is decreased with 15 in. rows, the overall plant spacing within the row is increased.
