2009 Results

Our 2009 Corn Club has broken records again, averaging 224 bushels per acre. What an achivement!

This marks the 20th year I have been involved with the Corn Club and am amazed at the progress participants in the program have made. This year we graphed the average corn yields for the past 20 years and found that on average corn yields have increased by 3.6 bushels per acre per year. Individual members who have been part of the program have recorded similar progress. This is roughly twice the growth rate in the state average corn yields. Plant populations have continued to climb, averaging nearly 31,000 this year and those of the top 10 in each class averaged about 33,000. It is also interesting to note that soil insecticide use has really dropped off as well as postemergent herbicides other than glyphosate products. In addition, many fields appeared to have had much less than the 1.0 lb of N/ bushel applied, and still produced very high yields. Certainly weather played a big role this year, but this years performance is still a big function of genetics and top management by our corn growers.

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. Thanks also to the Pennsylvania Corn Growers Association for sponsoring the program—check out their membership program included in this years report. 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.
