| 1. Yields calculated at 15.5% moisture. | ||||||||||
| 2. 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). |
