1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 6.9%, and df for EMS = 48.
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 22, 2000.
Harvested:	August 23, 2000.
Seeding Rate:	27,500 seeds/acre in 30" rows.
Soil Type:	Tifton loamy sand.
Soil Test:	P = High, K = Medium, and pH = 6.2.
Fertilization:	99 lb N, 130 lb P₂O₅, and 195 lb K₂O/acre as preplant; 198 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Subsoiled, bedded, and rototilled; Aatrex, Prowl, and one cultivation used for weed control; Lorsban used for insect control; Nemacure used for nematode control; irrigated 11.0 inches.
