Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 6.8%, and df for EMS = 54.
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 21, 2005.
Harvested:
September 20, 2005.
Seeding Rate: 30,000 seeds/acre in 30" rows.
Soil Type:
Cecil clay loam.
Soil Test:
P = Medium, K = High, 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: Wheat.
Management:
Chisel plowed, disked, and rototilled; Atrazine, Lasso, and Basagran used for weed control;
Irrigated 0.5 inch.
Test conducted by P. A. Rose.
