Average yield per individual Kernza biomass (back transformed LS Mean grams ± 95% Confidence Limits) in pots with the four soil inoculation treatments (LW=living whole soil, SW= sterilized whole soil, LF= living prairie AM fungi, SF=sterilized prairie AM fungi) when Kernza was planted in monoculture (A), with alfalfa (B), and with Silphium (C). The dots are the observed responses for each treatment. Bars with different letters within each cropping treatment are significantly different (Tukey’s HSD multiple comparison).
