Data represent the means of four plots per treatment in the field assay.

Values in the same column followed by the same lower case letter did not differ significantly at P > 0.05 (Tukey’s test).

Values in the same line followed by the same upper case letter did not differ significantly at P > 0.05 (Tukey’s test).
