Western Research and Demonstration Farm
Corn hybrid genetics change yearly to increase productivity. The newer hybrids appear to possess plant characteristics that allow for higher plant populations. Over the past several years, 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, these data will be combined into a larger data set of similar trials for statewide recommendations.
