Yields from soybean contests can offer an estimate of the yield potential of current cultivars in a region. Since record soybean yields were obtained by a farmer in Missouri (139 to 161 bu ac-1 in 2006, 2007, and 2010), several other states in the U.S. have crossed the 100 bu ac-1 threshold. In Kentucky, maximum contest yields have increased on average since 2002, but the highest yield reported is still below 100 bu ac-1 (98.4 bu ac-1 in 2015). Understanding what are the main limiting factors for soybean production in KY, and quantifying the environmental potential of current soybean cultivars, is critical for developing management recommendations that can increase both maximum and average...
