*  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 = 8.6%, and df for EMS = 36.
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 10, 2002.
Harvested: September 11, 2002.
Seeding Rate: 23,000 seeds/acre in 30" rows.
Soil Type: Rome gravelly clay loam.
Soil Test: P = High, K = High, and pH = 6.5.
Fertilization: 50 lb N, 47 lb P2O5, and 70 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Chisel plowed, disked, and rototilled; Lasso, Aatrex and Accent used for weed control.
Test conducted by P. A. Rose, G. Rawls, and J. Stubbs.
