Effect of the microbial inoculants on biomass, P extraction at shoot, stover (culm and cobs), and grain level and P fertilizer recovery efficiency. For each line, different letters (mean ± SD of 3 sampling plots, n = 3) show significance at 5% level (no letters mean not significant), according to Tuckey’s HSD test.
