The purpose of this study is to evaluate 7.5 in. and 15 in. row spacing and their effect on yield.

2017 Southern Illinois Wheat Row Width Study

Contrary to the 2016 row width study, this year we experienced a rain event during and shortly after planting. The drastic differences we saw last year in uniformity of emergence and seed-to-soil contact were not nearly as evident this season. However, the 15 in. wheat still had an advantage on emergence compared to the drilled wheat. The results this year were much closer and showed a slight advantage to the drilled wheat. Our two-year data for this study now supports a 6.5 Bu./A. average yield gain wit h 15 in. rows.
