Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 5.6%, and df for EMS = 39.
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 2, 2004.
Harvested:
August 24, 2004.
Seeding Rate:
31,000 seeds/acre in 30" rows.
Soil Type:
Pacolet coarse sandy loam.
Soil Test:
P = Medium, K = Medium, and pH = 6.3.
Fertilization:
49 lb N, 98 lb P2O5, and 147 lb K2O/acre as preplant; 200 lb N/acre as sidedress.
Previous Crop:
Soybeans.
Management:
Moldboard plowed, disked, and rototilled; Aatrex, Lasso, Basagran, and one cultivation used for
weed control; irrigated 3.5 inches.
Test conducted by P. A. Rose.
