  1. The growth parameters of eggplant plants were obtained on the 14th day after the end of the treatment. The results are shown as the mean ± SE of three replicates, and the different letters denote significant differences between treatments (p < 0.05), according to Duncan's multiple range tests. 0 mmol L−1: control.
