Phenological and ecophysiological responses of Capsicum annuum var. glabriusculum to native arbuscular mycorrhizal fungi and phosphorus availability

•Results showed a high sunlight regimes and a high thermal time during growing season.•P availability and the levels of AMF propagules in the soil significantly modified the macro and micro-nutrient acquisition patterns and biomass allometric allocation.•Mycorrhizal growth responses decreased as the availability of P increases.•The reproductive yield was promoted by the native AMFCag inoculum.•A high functional AMF colonization (predominantly Arum-Paris type) was promoted by the AMFCag inoculum except at higher levels of P availability.
