*  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 = 8.2%, and df for EMS = 33.
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 3, 2001.
Harvested: August 23, 2001.
Seeding Rate: 24,500 seeds/acre in 30" rows.
Soil Type: Dothan sandy loam.
Soil Test: P = Medium, K = Medium, and pH = 5.6.
Fertilization: 18 lb N, 54 lb P2O5, and 108 lb K2O/acre as preplant; 174 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Subsoiled and strip tilled; Aatrex, Prowl, and Permit used for weed control: irrigated 7.0 inches.
Test conducted by D. L. Wright and B. Kidd.
