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 = 12.1% and df for EMS = 20.
6. CV = 10.5% and df for EMS = 30.
7. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated.
8. CV = 9.3% and df for EMS = 34.
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 28, 1999.
Harvested: Maturity Group V - October 18, 1999.
Maturity Group VI - November 4, 1999.  
Maturity Groups VII & VIII - November 9, 1999.  
Seeding Rate: Eight viable seeds per foot in 30" rows.
Soil Type: Cecil coarse sandy loam.
Soil Test: P = High, K = Medium, and pH = 6.4.
Fertilization: 0 lb N, 50 lb P2O5, and 100 lb K2O/acre.
Previous Crop: Grain sorghum.
Management: Chiseled and disked; Micro-Tech Lasso, Treflan, Classic, and one cultivation used for weed control; Telone II used for nematode control; irrigated four times totaling 4 inches.
