Agroforestry systems play a very important role in reducing wind speed, improving soil structure, increasing biodiversity and carbon sequestration [1]. One of the beneficial microbiota that have a symbiotic association with most of the plants in agroforestry is arbuscular mycorrhizal fungi (AMF) [2]. The diversity of AMF can be a critical factor in enhancing both the productivity and the diversity of plants in agroecosystems. However, very few studies have been carried out on the impact of mycorrhization on walnut trees with associated crops (e.g maize). The integration of a vegetal cover in intercrop in walnut plantations is an innovative practice, still little developed. Although cover crops are widely used in conservation agriculture or organic farming, there is little knowledge on the impact of cover crops on native mycorrhizal fungi. The aim of our study was to evaluate arbuscular mycorrhizal fungal community associated to walnut roots under agroforestry and agricultural systems
