1.  Yields calculated at 13% moisture.
2.  Lodging rating:  Rated 1 (all plants erect) to 5 (over 80% of plants down).
3.  Seed quality rating:  Rated 1 (very good) to 5 (very poor).
4.  CV = 8.8% and df for EMS = 58.
5.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value
     was not calculated.
6.  CV = 11.6% and df for EMS = 42.
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's
protected LSD (P = 0.10).
Planted: May 30, 2003.
Harvested: November 4, 2003.
Seeding Rate: Ten seeds per foot in 30" rows.
Soil Type: Rome gravelly clay loam.
Soil Test: P = Very High, K = Very High, and pH = 6.0.
Fertilization: 30 lb N, 60 lb P2O5, and 90 lb K2O/acre.
Previous Crop: Corn.
Management: Subsoiled, moldboard plowed, disked, and rototilled; Canopy XL, Classic, Basagran,
Pursuit, Select, and Poast Plus used for weed control; no irrigation water was applied.
Test conducted by P. A. Rose, G. Rawls, and J. Stubbs.
