**2.5 Statistical analysis**

Data collected were analyzed using a two-way analysis of variance (ANOVA). The analysis was performed using Minitab 19.2.0/October 2, 2019, a stable release developed at the Pennsylvania State University, USA by Minitab LLC. Where F-value was found to be significant (P ≤ 0.05), Tukey honest significant difference (HSD) was used to compare the interaction between soaking time and irrigation interval at P ≤ 0.05 level of significance [38].
