Corn hybrid genetics change yearly to increase productivity. The newer hybrids seem to allow for higher plant populations because of certain plant characteristics. Over the past several years several field trials across the state have found support for higher plant populations in corn. This trial was designed to collect information to aid in local recommendations. Additionally, this data will be combined into a larger data set of similar trials for statewide recommendations.
