*  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 = 6.9%, and df for EMS = 33.
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 30, 2002.
Harvested: October 17, 2002.
Seeding Rate: 26,500 seeds/acre in 30" rows.
Soil Type: Bradson clay loam.
Soil Test: P = High, K = High, and pH = 6.2.
Fertilization: 77 lb N, 77 lb P2O5, and 77 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Moldboard plowed and disked; Aatrex, Bicep and one cultivation used for weed control.
