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 2000 and reported at
lbs milk/ton of dry matter (DM) and lbs milk/acre.
3. CV = 6.3%, and df for EMS = 25.
4. CV = 8.8%, and df for EMS = 25.
5. CV = 6.8%, and df for EMS = 228.
Bolding indicates entries performing equally to highest performing entry within a column based on Fisher's protected
LSD (P = 0.10).

Evaluation of Corn Hybrids for Silage, 2010, Irrigated (Continued)
1. CV = 9.4%, and df for EMS = 75.
2. CV = 8.4%, and df for EMS = 75.
3. 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).
Planted:
March 29, 2010.
Harvested:
July 21, 2010.
Seeding Rate:
34,900 seeds/acre in 30" rows.
Soil Type:
Tifton loamy sand.
Soil Test:
P = High, K = Medium, and pH = 6.4.
87 lb N, 126 lb P2O5, and 213 lb K2O/acre as preplant; 274 lb N/acre as sidedress.
Fertilization:
Previous Crop:
Soybeans.
Subsoiled, bedded and rototilled; Atrazine, Prowl, Accent, and Basagran used for weed control;
Management:
Telone II used for nematode control; irrigated 8.0 inches.
Test conducted by A. Coy, R. Brooke and D. Dunn.

1. CV = 10.5%, and df for EMS = 57.
2. CV = 9.7%, and df for EMS = 57.
3. 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).
