Table 1 P- values of two way ANOVA evaluating the effect of AMF inoculation with Rhizophagus irregularis (AMF Inoc) and three soil Zn levels (Zn application) on above ground plant parts, grain yield and yield components, Spike Fertility Index, and P content and Zn concentrations and content in grain and straw of bread wheat and barley sampled at physiological maturity (Zadoks growth stage 90)

From: The mycorrhizal pathway of zinc uptake contributes to zinc accumulation in barley and wheat grain
