1. Yields calculated at 13% moisture.
2. Lodging rating: Rated 1 (all plants erect) to 5 (over 80% of plants down).
3. Seed quality rating: Rated 1 (very good) to 5 (very poor).
4. CV = 27.2% and df for EMS = 58.
5. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated.
6. CV = 19.9% and df for EMS = 42.
7. CV = 22.5% and df for EMS = 86.
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10).
Planted:	June 5, 2003.
Harvested:	October 23, 2003.
Seeding Rate:	Ten seeds per foot in 30" rows.
Soil Type:	Dothan loamy sand.
Soil Test:	P = Medium, K = Medium, and pH = 6.1.
Fertilization:	0 lb N, 0 lb P₂O₅, and 0 lb K₂O/acre.
Previous Crop:	Soybean.
Management:	Subsoiled and bedded, rototilled; Treflan, Basagran and 3 cultivations used for weed control; no irrigation water was applied.
