1.  Yields calculated at 15.5% moisture.
2.  Grain quality rating:  1 = excellent to 5 = poor.
3.  Grain moisture at harvest.
4.  CV = 9.1%, and df for EMS = 75.
5.  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).
