1.  CV = 11.7% and df for EMS = 27.
2.  The F-test indicated no statistical differences at the alpha = .10 probability lever; 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).
Planted: May 20, 2002.
Harvested: September 26, 2002.
