Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 8.7%, and df for EMS = 102.
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 27, 2006.
Harvested:
July 19, 2006.
Seeding Rate: 30,000 seeds/acre in 30" rows.
Soil Type:
Greenville sandy loam.
Soil Test:
P = Medium, K = High, and pH = 6.1.
Fertilization:
85 lb N, 150 lb P2O5, and 105 lb K2O/acre as preplant; 200 lb N/acre as sidedress.
Previous Crop: Soybean.
Management:
Subsoiled and rototilled; Prowl and Atrazine used for weed control; irrigated 14.0 inches.
Test conducted by A. E. Coy, R. Brooke, and R. Jackson.
