Preparing for Plant 21 (PFP21): Soybean Maturity Group
Soybean maturity groups (MG) are latitudinal zones developed to define where a soybean genetic package best fits based on photoperiod and temperature. Historically, most of NC has been slated for a MG6 zone, but we have growers interested in producing a wide range of MGs (3-8) for a variety of reasons. In a recent analysis of 877 NC Soybean Yield Contest entries, the single strongest predictor of high soybean yield was MG, with MG≤4 averaging 73 bu/A (54% of entries) and MG>4 averaging 55 bu/A (46% of entries).
