^ Two-year average of 1999 and 2000.
* Full-season hybrid.
1. Yields calculated at 15.5% moisture.
2. Grain quality rating: 1 = excellent to 5 = poor.
3. Grain moisture at harvest.
4. CV = 7.4%, and df for EMS = 42.
5. The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an 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: March 28, 2000.
Harvested: August 30, 2000.
Seeding Rate: 29,000 seeds/acre in 30" rows.
Soil Type: Dothan sandy loam.
Soil Test: P = Medium, K = High, and pH = 6.7.
Fertilization: 80 lb N, 90 lb P2O5, and 110 lb K2O/acre as preplant; 150 lb N/acre as sidedress.
Previous Crop: Cotton.
Management: Subsoiled and bedded; Aatrex, Dual, and one cultivation used for weed control; irrigated 21.0 inches.
            
Test conducted by A. E. Coy, M. D. Pippin, and R. D. McNeill, IV.
