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. Shattering rating: Rated 1 (no shattering) to 5 (>50% pods shattered).
5. CV = 10.6% and df for EMS = 32.
6. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, an LSD value
    was not calculated.
7. CV = 6.2% and df for EMS = 18.
8. CV = 9.9% and df for EMS = 48.
Bolding within each tests denotes entries with yields equal to the highest yielding entry based on Fisher's
protected LSD (P = 0.10).

Harvested: Maturity Group V - October 14, 1998.
  Maturity Group VI - October 23, 1998.
  Maturity Groups VII & VIII - November 7, 1998.
Seeding Rate: Eight viable seeds per foot in 30" rows.
Soil Type: Cecil coarse sandy loam.
Soil Test: P = High, K = Medium, and pH = 6.8.
Fertilization: 0 lb N, 0 lb P2O5, and 0 lb K2O/acre.
