1.  CV = 12.4%, and df for EMS = 66.
2.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an 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).
