1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 10.9%, and df for EMS = 36.
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:	April 11, 2000.
Harvested:	September 9, 2000.
Seeding Rate:	25,500 seeds/acre in 30" rows.
Soil Type:	Rome gravelly clay loam.
Soil Test:	P = High, K = Medium, and pH = 6.2.
Fertilization:	40 lb N, 45 lb P₂O₅, and 90 lb K₂O/acre as preplant; 100 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Moldboard plowed and rototilled; Aatrex and Lasso used for weed control.

Test conducted by P.A. Rose, G. Rawls, and J. Stubbs.
