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 = 52.
6. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, an LSD value was not calculated.
7. CV = 9.2% and df for EMS = 32.
8. CV = 11.1% and df for EMS = 62.
Bolding within each tests denotes entries with yields equal to the highest yielding entry based on Fisher's
protected LSD (P = 0.10).
Planted: May 13, 1998.
Harvested: Maturity Group V - October 7, 1998.
  Maturity Group VI - October 19, 1998.
  Maturity Groups VII & VIII - October 29, 1998.
Seeding Rate: Eight viable seeds per foot in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = High, K = Medium, and pH = 6.0.
Fertilization: 15 lb N, 45 lb P2O5, and 90 lb K2O/acre.
Previous Crop: Corn.
Management: Chisel plowed and rototilled; Trilin, Basagran, and 2 cultivations used for weed control; Dipel, Dimilin, and Karate used for insect control; irrigated 8 inches.
 
Test conducted by A. E. Coy, M. Pippin, and R. D. Kendrick.
