  1. Mean values followed by the same letter (a, b, c) in the horizontal column are not significantly different at 0.05% level of probability using Tukey’s post hoc test. Mean values followed by the same letter (A, B, C) in the vertical column are not significantly different at 0.05% level of probability using Tukey’s post hoc test
