1.  Yields calculated at 15.5% moisture.
2.  CV = 11.6%, and df for EMS = 39.
3.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an LSD value was
     not calculated.
4.  CV = 7.2%, and df for EMS = 27.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
