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 = 14.0% and df for EMS = .86
5. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated.
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 24, 2003.
Harvested:	October 30, 2003.
Seeding Rate:	Ten seeds per foot in 30" rows.
Soil Type:	Appling coarse sandy loam.
Soil Test:	P = Medium, K = High, and pH = 5.6.
Fertilization:	29 lb N, 56 lb P₂O₅, and 84 lb K₂O/acre.
Previous Crop:	Sorghum.
Management:	Chisel plowed, disked, and rototilled; Lasso, Canopy XL, and one cultivation used for weed control; irrigated 0.6 inch.
