Within the row for each location, means followed by the same letters are not significantly different according to LSD at P = 0.05.
*Significant at the 0.05 level based on analysis of variance.
**Significant at the 0.01 level based on analysis of variance.
Ns denotes non-significance based on analysis of variance.
