1.  Quality factors taken from the replicated silage trial at Tifton.
2.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an LSD value was not
     calculated.
Bolding indicates entries performing equally to highest performing entry within a column based on Fisher's protected
LSD (P = 0.10).
