Summary:

The second part of this presentation helps consultants, growers, and other practitioners specifically in the North-Central U.S. but has implications for anyone interested in maximizing corn yield. We discuss impacts of hybrid choice, plant population, planting date, row spacing, and crop rotation on yield. In addition, we talk about some factors limiting yield. This part presents data from National Corn Grower Association Corn Yield Contest winners and recent management from Iowa State University as a framework for the discussion. At the end of this presentation, you will understand the importance of optimum crop management practices in maximizing yield and consider the promises and challenges - of reaching a national average of 300 bushels per acre by 2030.
