1.  Yields calculated at 15.5% moisture.
2.  Disease rating:  1 = no rust to 5 = all leaves covered with rust.
3.  Grain moisture at harvest.
4.  CV = 6.5%, and df for EMS = 78.
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 3, 2002.
Harvested: August 12, 2002.
Seeding Rate: 30,000 seeds/acre in 30" rows.
Soil Type: Greenville sandy loam.
Soil Test: P = Low, K = Medium, and pH = 6.0.
Fertilization: 110 lb N, 100 lb P2O5, and 100 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop: Cotton.
Management: Subsoiled and rototilled; Aatrex and Prowl used for weed control; irrigated 9.0 inches.
