​Part 2 of this two-part presentation helps consultants, growers, and other practitioners specifically in the North Central U.S. but has implications for anyone interested in maximizing corn yield. The presentation discusses impacts of hybrid choice, plant population, planting date, row spacing, and crop rotation on yield. In addition, it addresses some factors limiting yield. Part 2 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, viewers 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.
