*  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 = 6.7%, and df for EMS = 72.
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 29, 2002.
Harvested: August 7, 2002.
Seeding Rate: 29,000 seeds/acre in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = High, K = Medium, and pH = 6.4.
Fertilization: 65 lb N, 130 lb P2O5, and 195 lb K2O/acre as preplant; 234 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Subsoiled and bedded, rototilled; Prowl, Atrazine, Permit and Accent used for weed control;
Telone II used for nematode control; irrigated 13.0 inches.
