1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 11.0%, and df for EMS = 90.
5. 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 18, 1999.
Harvested:	August 10, 1999.
Seeding Rate:	22,000 seeds/acre in 30" rows.
Soil Type:	Tifton loamy sand.
Soil Test:	P = High, K = Medium, and pH = 5.5.
Fertilization:	85 lb N, 70 lb P₂O₅, and 105 lb K₂O/acre as preplant; 80 lb N and 14 lb S/acre as sidedress.
Previous Crop:	Soybean.
Management:	Moldboard plowed and rototilled; Sutan, Accent, Permit and one cultivation used for weed control; Lorsban used for insect control.
