Yields were down slightly from last years record, but still were impressive given the widespread drought across the state this year. Plant populations continue to increase. This year final plant populations of the top ten entries in each class averaged just under 33000 plants per acre, indicating the higher populations producers are using on these higher yielding fields. The overall average population was just under 30000 this year. Despite these populations, lodging was generally not a problem in any fields.
Our summary of other production practices shows a similar breakdown to other years: many producers are sidedressing and N rates are often conservative compared to the yields achieved. We also find that the increase in corn club yields continues to outpace the state average yields by nearly twofold.
Congratulations to all the producers who participated in this year's program. Many thanks are due to the extension educators and crop consultants who help collect the yield and cultural information for the club. Also, a special thanks is due to Mark Antle in the Department of Crop and Soil Sciences for his diligent work in pulling this report together.
