Changes in a number of leaves; b plant height; c shoot fresh weight; d shoot dry weight; e root fresh weight; and f root dry weight of lettuce plants under different soil treatments. Error bars denote ± standard error (n = 3). For different parameters, letters “a,” “b,” and “c” represent significant differences among different soil treatments. According to Tukey’s test, the same letters on two bars imply that the plant growth parameters for these treatments are not significantly different at p < 0.05
