1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 13.6%, and df for EMS = 90.
5. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore a 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:	April 15, 2003.
Harvested:	September 8, 2003.
Seeding Rate:	28,000 seeds/acre in 30" rows.
Soil Type:	Waynesboro loam.
Soil Test:	P = High, K = High, and pH = 6.4.
Fertilization:	75 lb N, 90 lb P₂O₅, and 180 lb K₂O/acre as preplant; 200 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Subsoiled, chisel plowed, disked, and rototilled; Aatrex, Lasso, and Accent used for weed control; no irrigation water applied.
