What can we learn from soybean yield contest winners? Larry Purcell, University of Arkansas, has some answers based on three years of documenting how Kip Cullers, Stark City, MO, grew 160.6‐bu/ac soybeans in 2010 and 139 bu/ac previously. This article addresses the controversy of adding nitrogen (N) fertilizers to soybeans, as some yield contest winners are assumed to have done, and identifies some of Cullers’ important practices to increase yields and profits for more mainstream soybean growers. In addition, we examine the profitability of yield‐increasing practices as verified by 60 site‐years of data.
