| 1. Yields calculated at 15.5% moisture. | |||||||||||
| 2. Grain quality rating: 1 = excellent to 5 = poor. | |||||||||||
| 3. Grain moisture at harvest. | |||||||||||
| 4. CV = 6.5%, and df for EMS = 24. | |||||||||||
| 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). | |||||||||||
