1. CV = 8.4% and df for EMS = 36.
2. CV = 11.3% and df for EMS = 36.
3. The F-test indicates no statistical differences at the alpha = 0.10 probability level; therefore, an LSD
value was not calculated.
4. CV = 14.3% and df for EMS = 35.
5. CV = 14.7% and df for EMS = 35.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's
protected LSD (P = 0.10).
Planted:
May 31, 2012.
Harvested:
August 31, 2012.
Ratoon: November 19, 2012.
Seeding Rate:
150,000 seed/acre in 30" rows.
Soil Type:
Appling coarse sandy loam.
Soil Test:
P = High, K = High, and pH = 6.1.
Fertilization:
Preplant: 50 lb N, 100 lb P2O5, and 150 lb K2O/acre. Sidedress: 100 lb N/acre.
Previous Crop: Fallow.
Management:
Moldboard plowed, disked, and rototilled; Atrazine, Basagran, and one cultivation
used for weed control.
Test conducted by J. Gassett and G. Ware.
