1. Yields calculated at 14% moisture.
2. Days from planting to 50% bloom.
3. Rated 1 = resistant to 5 = susceptible to foliar diseases.
4. Percent of grain head damaged.
5. CV = 8.0% and df for EMS = 60.
6. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was not calculated.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0.10).
Planted: April 16, 1999.
Harvested: August 18, 1999.
Seeding Rate: 88,000 seed/acre in 30" rows.
Soil Type: Tifton loamy sand.
Soil Test: P = Medium, K = High, and pH = 6.2.
Fertilization: Preplant: 55 lb N, 50 lb P2O5, and 75 lb K2O/acre. Sidedress: 50 lb N and 8 lb S/acre.
Previous Crop: Cotton.
Management: Moldboard plowed and rototilled; Aatrex and two cultivations used for weed control; Lanate and Karate used for insect control.
