1.  Yields calculated at 14% moisture.
2.  Days from planting to 50% bloom.
3.  CV = 10.4% and df for EMS = 66.
4.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was
     not calculated.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
