Yields calculated at 14% moisture.
Days from planting to 50% bloom.
Rated 1 = resistant to 5 = susceptible to foliar diseases.
Percent of grain head damaged.
CV = 18.4% and df for EMS = 33.
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 18, 2007.
Harvested:
August 22, 2007.
Seeding Rate:
140,000 seed/acre in 30" rows.
Soil Type:
Dothan loamy sand.
Soil Test:
P = Medium, K = Low, and pH = 6.2.
Preplant: 50 lb N, 0 lb P 2O5, and 97 lb K 2O/acre. Sidedress: 71 lb N/acre.
Fertilization:
Previous Crop:
Peanuts.
Management:
Subsoiled, bedded, and rototilled; Aatrex and two cultivations used for weed control;
Lorsban used for insect control.
Test conducted by A. E. Coy, R. Brooke, and R. Jackson.
