1.  Yields calculated at 14% moisture.
2.  Days from planting to 50% bloom.
3.  CV = 19.3% and df for EMS = 66.
4.  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: May 13, 2002.
Harvested: July 28, 2002.
Seeding Rate: 150,000 seed/acre in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = Low, K = Medium, and pH = 6.0.
Fertilization: Preplant:  80 lb N, 80 lb P2O5, and 80 lb K2O/acre.  Sidedress:  58 lb N/acre.
Previous Crop: Grain sorghum.
Management: Subsoiled and bedded, rototilled; Aatrex, Permit, and one cultivation used for weed control;
Lorsban used for insect control.
