1.  Yields calculated at 15.5% moisture.
2.  Grain quality rating:  1 = excellent to 5 = poor.
3.  Grain moisture at harvest.
4.  CV = 9.1%, and df for EMS = 75.
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 4, 2003.
Harvested:	August 26, 2003.
Seeding Rate:	31,000 seeds/acre in 30" rows.
Soil Type:	Pacolet coarse sandy loam.
Soil Test:	P = Medium, K = High, and pH = 6.1.
Fertilization:	49 lb N, 98 lb P2O5, and 147 lb K2O/acre as preplant; 200 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Moldboard plowed, disked, and rototilled; Aatrex, Lasso, and one cultivation used for weed control; irrigated 1.0 inch.
