* Nonirrigated in 2000.
^# NOTE: The southeastern states endured a very wet fall caused by two tropical storms and one hurricane. Excessive rainfall along with persistent cloudy, drizzly conditions delayed soybean harvest, thus severely impacting soybean quality
and maturity to degree that the data is not included in this final report and will not be used in the long term soybean quality and maturity averages.

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. Shattering rating: Rated 1 (no shattering) to 5 (>50% pods shattered).
5. CV = 11.2% and df for EMS = 62.
6. 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 21, 2002.
Harvested:	November 22, 2002.
Seeding Rate:	Ten seeds per foot in 30" rows.
Soil Type:	Cecil coarse sandy loam.
Soil Test:	P = Medium, K = High, and pH = 6.0.
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 3.5 inches.
