Summary of Evaluations of Corn Hybrids for Silage
Blairsville, Calhoun, Griffin, and Tifton, Georgia, 2007 (Continued)
1. Quality factors taken from the replicated silage trial at Tifton.
2. This variable is calculated using University of Wisconsin Corn Silage Evaluation System - Milk 2006 and reported at
lbs milk/ton of dry matter (DM) and lbs milk/acre.
3. CV = 3.0%, and df for EMS = 30.
4. CV = 4.8%, and df for EMS = 30.
5. CV = 10.4%, and df for EMS = 117.
6. 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).

2. CV = 10.8%, and df for EMS = 51.
3. 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).
