“…Arbuscular mycorrhizal fungi (AMF) are obligate biotrophs, forming symbiotic associations with the majority of vascular plants, including most crops 19 . The fungal mycelia colonize and interconnect roots of different crops, forming common mycorrhizal networks that bound to the outcomes of plant facilitative or competitive interactions and allow direct and efficient pathways of resource transfers between intercrops 20 . In a legume-based intercropping system, AMF are essentially needed to alleviate the nutrient shortages and support the extra P need for N fixation 21 .…”

Intercropping is one of the most important components of sustainable agriculture. The effects of chemical fertilizer (CF), arbuscular mycorrhizal fungi (AMF) (Glomus sp.) and AMF + nitrogen-fixing bacteria (NFB) including Azospirillum and Azotobacter (AMF + NFB) was studied on essential oil yield and compositions of Moldavian balm (Mb) (Dracocephalum moldavica L.) in sole cropping and intercropping with fenugreek (F) (Trigonella foenum-graecum L.). The experiment was conducted during 2020 and 2021 growing seasons in East Azarbayhan, Iran. The highest dry herbage yield (6132 kg ha−1) was obtained in Mb:F(4:2) and CF treatment. After sole Moldavian balm, the highest essential oil yield (15.28 kg ha−1) was obtained in Mb:F (4:2) and AMF + NFB treatment. Geranial, geranyl acetate, geraniol, neral, and nerol were the main chemical constituents of essential oil. In AMF + NFB treatments the geranial contents in intercropping patterns of Mb:F (1:1), (2:2) and (100:50), increased by 25.1, 15.5 and 34.6% compared with sole Moldavian balm. The highest LERT values were observed in Mb:F (100:50) cropping pattern in 2021 (1.70 and 1.63 for CF and AMF + NFB treatments). Generally, it can be concluded that Mb:F (100:50) intercropping and use of AMF + NFB bio-fertilizer could be recommended to medicinal plant growers in sustainable production systems.

“…In addition, the fungal mycelia simultaneously colonize and interconnect roots of the same or different plant species, forming so-called common mycorrhizal networks (CMNs). The CMNs allow direct and efficient pathways of resource transfers between intercrops, and closely bound to the outcomes of plant facilitative or competitive interactions (Montesinos-Navarro et al, 2016;Qiao et al, 2016;Dieng et al, 2017). Furthermore, AM fungi can provide a bunch of services for plant adaptation under stressful environments (Gorzelak et al, 2015), facilitating the ecological functions and wider applications of intercropping (Ehrmann and Ritz, 2014).…”

Intercropping, which gains productivity and ecological benefits through plant facilitative interactions, is a practice often associated with sustainable agriculture. In such systems, arbuscular mycorrhizal (AM) fungi and the hyphal networks play key roles in plant facilitation by promoting connectivity, mediating interplant transfer of metabolic resources, and managing weeds, pathogens, and contaminants. This review states that the symmetrically or unsymmetrically delivered resources via AM fungi are imperative to maintain facilitative interactions between intercrops. In addition, the responses of AM fungi to intercropping are also discussed, including changes in abundance, diversity, community composition and colonization level. Although general proliferations in AM fungi via intercropping have been shown, the plant hosts and neighbors may exert different influences on AM fungi. Therefore, further research is needed in quantifying the mediating role of AM fungi on outputs of intercropping systems, clarifying the driving forces, and exploring the causation between these processes and the changes in AM fungi themselves. To conclude, the integration with AM fungi extends the understanding of key soil biological processes driving plant facilitation and will guide efforts to optimizing intercropping systems.
