Values are mean ± Standard error of three replications, indicates statistically significant at with control, indicates statistically significant at (highly significant deference with control), ns indicates not statistically significant. Means in each column followed by the same letter are not significantly different at according to Fisher’s LSD, RSR = Root to shoot ratio (Root dry weight divided by shoot dry weight).
