* Full-season hybrid.
1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 7.4%, and df for EMS = 42.
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 24, 2000.
Harvested:	August 28, 2000.
Seeding Rate:	27,500 seeds/acre in 30" rows.
Soil Type:	Greenville sandy clay loam.
Soil Test:	P = Medium, K = High, and pH = 6.1.
Fertilization:	100 lb N, 100 lb P2O5, and 70 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Subsoiled and rototilled; Aatrex, Prowl, and Starfire used for weed control; irrigated 8.5 inches.
