| 5. CV = 5.4% and df for EMS = 57. | |||||||||
| 6. The F-test indicated
no statistical differences at the alpha = .10 probability level; therefore,
a 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). |
