1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 8.8%, and df for EMS = 84.
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 30, 2003.
Harvested:	October 9, 2003.
Seeding Rate:	26,500 seeds/acre in 30" rows.
Soil Type:	Bradson clay loam.
Soil Test:	P = Very High, K = High, and pH = 6.3.
Fertilization:	77 lb N, 77 lb P₂O₅, and 77 lb K₂O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Moldboard plowed and disked; Aatrex, Bicep, Basagran, and one cultivation used for weed control.
