*  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 = 14.5%, and df for EMS = 66.
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: March 25, 2002.
Harvested: August 6, 2002.
Seeding Rate: 24,000 seeds/acre in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = High, K = Medium, and pH = 6.3.
Fertilization: 35 lb N, 70 lb P2O5, and 105 lb K2O/acre as preplant; 145 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Subsoiled and bedded, rototilled; Prowl, Atrazine, Accent, and Permit used for weed control;
Telone II used for nematode control.
