*  Full-season hybrid.
1.  Yields calculated at 15.5% moisture.
2.  2-Year average:  2001 and 2002.
3.  Grain quality rating:  1 = excellent to 5 = poor.
4.  Grain moisture at harvest.
5.  CV = 6.5%, and df for EMS = 33.
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 5, 2002.
Harvested: September 3, 2002.
Seeding Rate: 29,000 seeds/acre in 30" rows.
Soil Type: Cecil sandy clay loam.
Soil Test: P = High, K = High, and pH = 6.5.
Fertilization: 49 lb N, 98 lb P2O5, and 147 lb K2O/acre as preplant; 200 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Moldboard plowed, disked, and rototilled; Aatrex, Lasso and one cultivation used for weed control;
irrigated 3.3 inches.
