Means of the same growing season designated with different lower-case letters indicate significant differences among treatments according to the Duncan’s Multiple Range test (P < 0.05). Values are means ± standard deviation (SD) from four replicates (Means ± SD). ***, **, *, and ns denote significance at P < 0.001, P < 0.01, P < 0.05, and non-significant, respectively. ^† Potassium silicate.; ^‡ Fresh water.; ^§ Saline water.
