Values followed by the same letter in columns are not different at p < 0.05 by Duncan’s multiple range test, a = Very highly significant (Very high result), b = Highly significant (High result), c = Significant (Intermediate result), than that d-i mean less significant (Less result), and the same letters were not significant
