| 1. Yields calculated at 15.5% moisture. | |||||||||
| 2. Grain quality rating: 1 = excellent to 5 = poor. | |||||||||
| 3. Grain moisture at harvest. | |||||||||
| 4. CV = 17.0%, and df for EMS = 33. | |||||||||
| 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). |
