Stand Establishment Variability in Corn

Uniform stand establishment in corn is an important criterion for setting the stage for maximum grain yield. This presentation will focus on my recent research that re-evaluates the impact of uneven plant spacing on corn grain yield. Information will also be presented on factors that contribute to uneven plant spacing, emergence, and plant development.

Dr. Nielsen is a Professor of Agronomy at Purdue University with major responsibilities for Extension education in corn management systems for the state of Indiana. Originally from Nebraska, he joined the Agronomy staff at Purdue in 1982 after obtaining M.S. and Ph.D. degrees from the University of Minnesota. His current field research involves investigations into the effects of uneven plant spacing on corn grain yield, the potential for using crop canopy sensors to estimate plant N status, and the productive utilization of site-specific crop management tools. One of my major Extension activities is my ongoing development of Web-based corn information sites. Dr. Nielsen has two popular Web sites: they are the Corn Growers' Guidebook (http://www.kingcorn.org) and the Chat ‘n Chew Café (http://www.kingcorn.org/cafe).
