| 1. C.V. = 6.4%, and df for EMS = 63. | ||||||||
| 2. The F-test indicated no statisical difference at the alpha = 0.1 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). | ||||||||
