With planting season fast approaching, we should again consider how planting dates impact final yield. The importance of planting date is covered in the 2001 Iowa State University Extension publication, Corn Planting Guide, PM 1885. Several years of research have been conducted at both the Iowa State University Northeast Research and Demonstration Farm (Nashua) and the Iowa State University Southeast Research and Demonstration Farm (Crawfordsville) since that was printed. Each location has three years of data that we will review.
