Contrast statements indicate differences in mean between desiccant treatments. Means followed by the same letter within a column are not significantly different (p < 0.05). represents herbicides used as tank-mix; ns denotes non-significant at P < 0.05.
represents significant differences at P < 0.05 and P < 0.01, respectively, LSD denotes Fisher's least significant differences value at 0.05 level of probability.
