The 72 entries in the club this year averaged over 200 bushels per acre for only the second time in the history of the 5-Acre Corn Club. Although there has been some variation, average corn club yields have increased about 40 bushels per acre in the last ten years. All of these statistics are a reflection of the changes in productivity that are taking place in corn production. The management summaries for these producers suggest that in many ways corn production is becoming more sustainable. Well over half of our entries were no-tilled and more than 50% of the entrants sidedressed their N applications. Many of the entrants accounted for manure and previous crop credits and reduced or eliminated N fertilizer. One champion reported using no N fertilizer. The results also confirm that no-till production can result in yields as high as tilled corn production under the right management. Many of the top yielding fields also were planted to corn rootworm resistant hybrids this year and the use of row insecticides has dropped dramatically. All of these are postive trends in my view.
Congratulations to all the producers who participated in this years program. Many thanks are due to the extension agents 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.
