ZnFe2O4 NPs and AM fungal effects on: (a) leaves number and (b) root/shoot ratio of pea plants. Control: represents non-treated pea plants; AM: represents pea plants inoculated with AM fungi; Zn/Fe NPs: pea plants treated with ZnFe2O4 NPs and AM + Zn/Fe NPs: represents pea plants dually treated with AM fungi and ZnFe2O4 NPs. Data are the mean of three replicates ± standard error (n = 3). Different letters above bars indicate a significant difference between treatments using ANOVA followed by Duncan’s multiple range test (p < 0.05).
