Résumé
To illustrate the effect of arbuscular mycorrhizal fungi (AMF) origin on plant development and resource distribution between rice and bean in intercropping, three groups of AMF were used from soil rhizospheric of these two plants. The combination of AMF from rice and common bean stimulated the development of both cultivated plants and increase the concentration of P and N mineral on aerial part. Our work suggests that the origin of AMF contributes to increase yield and to reduce the use of organic, mineral or chemical amendment in rice-bean intercropping.
