Shattering rating: Rated 1 (no shattering) to 5 (>50% pods shattered). 5. CV = 5.5% and df for EMS = 18. 6. CV = 8.5% and df for EMS = 20. 7. CV = 9.2% and df for EMS = 34. 8. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, an LSD value was not calculated. Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10). Planted: June 5, 1997. Harvested: Maturity Group V - October 10, 1997. Maturity Group VI - November 5, 1997. Maturity Groups VII & VIII - November 11, 1997. Seeding Rate: Eight viable seeds per foot in 30" rows. Soil Type: Cecil coarse sandy loam. Soil Test: P = High, K = Medium, pH = 6.8. Fertilization: Preplant: 0 lb N, 50 lb P205, and 100 lb K20/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; subsoiled between rows after cultivation; irrigated three times totaling 3 inches. Test conducted by E. D. Wood, G. B. Rowan, J. T. Griner, J. L. Head, Jr., S. L. Finnerty, R. J. Rogers, and R. M. Smith.
