Soybean Agronomics
Many changes have occurred over the last 15 years that have caused questions about current soybean agronomics. Biotechnology has made weed management ‘easier’ and fungicide and insecticide soybean seed treatments are more common. In addition, soybean seed costs, as well as labor, fuel, and equipment costs, have significantly increased. As a result, soybean seeding rates are decreasing and in some operations row widths are increasing. Attendees of the 2010 Illinois Corn and Soybean Classics were asked how they had changed soybean seeding rates in the previous five years, and of 574 respondents, 50% decreased 0 to 20,000 seeds per acre and 28% decreased by more than 20,000 seeds per acre. Recent data will be discussed to shed light on current soybean agronomic decisions.

BIO: Vince Davis is an Assistant Professor of Soybean Production Systems in the Department of Crop Sciences at the University of Illinois. He grew up on a farm in Northwest Illinois and earned a B.S. in agronomy from Western Illinois University and a M.S. and Ph.D. in Weed Science from Purdue University. His research program is evaluating soybean agronomics to develop informed management recommendations, evaluating inputs and practices to increase soybean yields, and evaluating doublecrop soybean systems to increase year-long system productivities.
