Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 15.6%, and df for EMS = 27.
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 3, 2006.
Harvested:
August 3, 2006.
Seeding Rate: 33,000 seeds/acre in 30" rows.
Soil Type:
Cecil sandy clay loam.
Soil Test:
P = High, K = High, and pH = 5.6.
Fertilization:
75 lb N, 100 lb P2O5, and 150 lb K2O/acre as preplant; 200 lb N/acre as sidedress.
Previous Crop: Wheat.
Management:
Moldboard plowed, disked, rototilled; Atrazine and Lasso used for weed control; irrigated 3.0 inches.
Test conducted by P. A. Rose.
