1.  Percent leaf at first clipping.
2.  CV = 14.2% and df for EMS = 69.
3.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was
     not calculated.
4.  CV = 11.3% and df for EMS = 42.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0/10).
