(A) Pot experiments of Vigna radiata (green gram) treated with control (a), strain KhEc 44 (b), strain KhEc 50 (c), strain KhEc 68 (d) and strain KhEc 69 (e). Values are mean ± standard deviation (n = 30). A two-way ANOVA was performed to determine the effect of bacterial treatment on plant growth parameters and as * significant at the level P < 0.0332; ** significant at the level P < 0.0021; *** significant at the level P < 0.0002, **** significant at the level P < 0.0001 respectively. (B) PCA plot of pot experiments of Vigna radiata (green gram) treated with control (a), strain KhEc 44 (b), strain KhEc 50 (c), strain KhEc 68 (d) and strain KhEc 69 (e).
