1.  Yields calculated at 15.5% moisture.
2.  Grain quality rating:  1 = excellent to 5 = poor.
3.  Grain moisture at harvest.
4.  Disease rating:  1 = resistant to 5 = highly susceptable.
5.  CV = 7.5%, and df for EMS = 66.
6.  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 1, 2003.
Harvested:	August 15, 2003.
Seeding Rate:	26,000 seeds/acre in 36" rows.
Soil Type:	Dothan sandy loam.
Soil Test:	P = Medium, K = Medium, and pH = 5.6.
Fertilization:	18 lb N, 54 lb P2O5, and 108 lb K2O/acre as preplant; 153 lb N/acre as sidedress.
Previous Crop:	Soybean.
Management:	Subsoiled and strip tilled; Aatrex, Prowl, Permit, and Accent used for weed control; Phorate and Lorsban used for insect control; no irrigation water applied.
