Tifton, Georgia:
Evaluation of Sorghum Hybrids for Silage, 2010
(Continued)
1. CV = 11.8% and df for EMS = 39.
2. CV = 12.6% and df for EMS = 39.
3. The F-test indicates no statistical differences at the alpha = .10 probability level; therefore, a LSD
value was not calculated.
4. CV = 14.8% and df for EMS = 39.
5. CV = 16.7% and df for EMS = 39.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's
protected LSD (P = 0.10).
Planted:
April 16, 2010
Harvested:
July 28, 2010.
Ratoon: October 18, 2010.
Seeding Rate:
150,000 seed/acre in 30" rows.
Soil Type:
Tifton sandy loam.
Soil Test:
P = Very High, K = Medium, and pH = 6.9.
Preplant: 87 lb N, 126 lb P2O5, and 213 lb K2O/acre. Sidedress: 125 lb N/acre.
Fertilization:
Previous Crop: Soybeans.
Subsoiled, bedded, and rototilled; Lorsban used for insect control.
Management:
Test conducted by A. Coy, R. Brooke and D. Dunn.
