1.  Yields calculated at 15.5% moisture.
2.  Grain quality rating:  1 = excellent to 5 = poor.
3.  Grain moisture at harvest.
4.  CV = 14.6%, and df for EMS = 51.
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: March 25., 2002.
Harvested: August 6, 2002.
Seeding Rate: 25,500 seeds/acre in 36" 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; 153 lb N/acre as sidedress.
Previous Crop: Soybean.
Management: Subsoiled and strip tilled; Aatrex, Prowl, Permit and Accent used for weed control;
Phorate and Lorsban used for insect control; irrigated 5.0 inches.
