*  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 = 7.7%, and df for EMS = 63.
5.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an 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 10, 2001.
Harvested: August 22, 2001.
Seeding Rate: 27,500 seeds/acre in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = High, K = Medium, and pH = 6.5.
Fertilization: 65 lb N, 130 lb P2O5, and 195 lb K2O/acre as preplant; 128 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Paraplowed, subsoiled, bedded, and rototilled; Prowl, Atrazine, Permit, and Accent used for
weed control; Nemacur used for nematode control; Furadan used for insect control.
Test conducted by A. E. Coy, M. D. Pippin, R. Brooke, and T. Hancock.
