Unique rhizosphere metabolites, such as benzoxazinoids (BXs), are secreted by cereal crops, wheat, which influence the microbiota and affect growth of offspring crops. However, feedback effect this interaction on environment neighboring intercropped plants their performance remains unclear. This study combined pot field experiments to explore intercropping system between wheat (IW) fava bean (IF). Compared with monoculture (MW), IF significantly increased BXs release from roots enhanced synthesis in both leaves roots. not only drove changes diversity richness but also altered composition through horizontal transfer. Actinomycota, dominant bacterial phylum, was strongly influenced IF, showing a positive correlation Pseudomonadota. In terms fungi, promoted enrichment Penicillium IW while inhibiting Fusarium Gibberella. The BXs-driven enzyme activities, including CAT, urease, sucrase, neutral phosphatase, soil. These improved aboveground (plant height, leaf length, fresh weight) belowground (root length root well crop grain yield. conclusion, demonstrates for first time that promote interactions rhizosphere, improving soil activities overall plant wheat-fava system.
