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 = 15.8% and df for EMS = 18.
6. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated.
7. CV = 12.4% and df for EMS = 26.
8. CV = 6.2% and df for EMS = 48.
Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10).
Planted: Maturity Groups V & VI - May 15, 2000.

  Maturity Group VI - October 23, 2000.
  Maturity Groups VII & VIII - November 2, 2000.
Seeding Rate: Eight viable seeds per foot in 30" rows.
Soil Type: Maturity Groups V & VI - Pacolet sandy loam.
  Maturity Groups VII & VIII - Cecil coarse sand loam.
Soil Test: Maturity Groups V & VI - P = Medium, K = High, and pH = 6.5.
  Maturity Groups VII & VIII - P = Medium, K = Medium, and pH = 6.9.
Fertilization: 0 lb N, 45 lb P2O5, and 90 lb K2O/acre.
Previous Crop: Grain sorghum.
