*  Full-season hybrid.
1.  Yields calculated at 15.5% moisture.
2.  Grain quality rating:  1 = excellent to 5 = poor.
3.  Grain moisture at harvest.
4.  CV = 8.0%, and df for EMS = 51.
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 15, 2003.
Harvested:	September 11, 2003.
Seeding Rate:	23,000 seeds/acre in 30" rows.
Soil Type:	Waynesboro loam.
Soil Test:	P = High, K = High, and pH = 6.4.
Fertilization:	50 lb N, 47 lb P2O5, and 70 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Subsoiled, chisel plowed, disked and rototilled; Aatrex, Lasso, and Accent used for weed control.
Test conducted by P.A. Rose, G. Rawls, and J. Stubbs.
