This presentation will help consultants, growers, and other practitioners in the U.S. on the basic mechanisms to maximize soybean yield. Examples will be given from Iowa that can be used for most states in the upper Midwest. In the presentation, basic soybean growth and development will be presented, and then this topic will be linked to management decisions. By the end of this presentation, the practitioner should know more about what it takes to maximize soybean yield, that it is all about agronomics and variety selection, and that yield is made much earlier in the growing season that most people think.
