Variable rate seeding prescription evaluate in corn (2018-2020)

The purpose of this study is to evaluate different methodologies for developing variable rate seeding prescriptions in corn. Three prescription methods will be evaluated on yield and economics compared to a farmer chosen uniform rate. The three variable rate methods are normalized yield, topographic wetness index, and Corn Suitability Rating. This will be conducted in central Iowa in 2018 and 2019.
