Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 30.5%, and df for EMS = 30.
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 11, 2006.
Harvested:
August 30, 2006.
Seeding Rate: 25,500 seeds/acre in 30" rows.
Soil Type:
Rome gravelly clay loam.
Soil Test:
P = High, K = Very High, and pH = 5.5.
Fertilization:
20 lb N, 45 lb P2O5, and 120 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop: Soybean.
Management:
Chisel plowed, disked, and rototilled; Atrazine, Lasso, and one cultivation used for weed control;
Warrior used for insect control.
Test conducted by P. A. Rose and J. Stubbs.

Yields calculated at 15.5% moisture.
Grain quality rating: 1 = excellent to 5 = poor.
Grain moisture at harvest.
CV = 11.1%, and df for EMS = 36.
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).
