Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...
