Effect of Somerville solution concentration (EC in dS m−1) and phosphate level on rosette fresh weight (g plant−1). Hoagland solution served as control (Exp. 2). Error bar represents the 95% confidence intervals of the least square (LS) means (n = 4 with each replicated represented by 3 plants). Means sharing the same letter are not significantly different (P > 0.05, Tukey adjusted comparisons)
