Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 9.4%, 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 10, 2008.
Harvested:
September 10, 2008.
Seeding Rate:
30,000 seeds/acre in 30" rows.
Soil Type:
Cecil sandy loam.
Soil Test:
P = Medium, K = High, and pH = 6.4.
70 lb N, 140 lb P2O5, and 210 lb K2O/acre as preplant; 100 lb N/acre as sidedress.
Fertilization:
Previous Crop:
Soybean.
Disked and rototilled; Atrazine, Lasso and one cultivation used for weed control;
Management:
irrigated 12 inches.
Test conducted by J. Gassett and G. Ware.
