The present work aimed to analyse whether and how single or dual inoculation with arbuscular mycorrhizal fungi (Funneliformis mosseae, Paraglomus occultum, and Rhizophagus intraradices) and rhizobia (Rhizobium trifolii) improved plant growth and stimulated nitrogen (N) acquisition of white clover. AMF inoculation significantly (P < 0.05) increased root nodule number by 117‒173%, and additional Rh considerably stimulated mycorrhizal growth. Single AMF or Rh treatment dramatically increased shoot by 36‒281% and root biomass by 16‒36% than non-inoculated control, and dual inoculation of Rh and P. occultum or R. intraradices further magnified the positive effect. Leaf and root N content, root total soluble protein content, root nitrogenase activity, and amino acid (e.g., alanine, arginine, asparagine, aspartate, phenylalanine, proline, and tryptophan) concentrations were significantly increased by single or dual inoculation, while dual inoculation of AMF and Rh had significantly superior roles than single corresponding AMF or Rh inoculation. These results suggested that AMF and Rh represented synergetic effects on accelerating N acquisition of white clover to some extent, while the combination of P. occultum and Rh was the best.

It is widely accepted that the symbiotic arbuscular mycorrhizal fungi (AMF) play a key role in sustainable production systems in rice cultivation and they readily form a symbiotic relationship with these fungi. Four species consortium of AMF, Funneliformis mosseae, Rhizophagus intraradices, Clariodeoglomus etunicatum and Glomus aggregatum, produced through in vitro production system and formulated with organic biostimulants viz. humic acids and sea weed extract were tested in this experiment, both for direct seeded and transplanted paddy, under anaerobic cultivation system. AMF inoculated fields produced significantly higher yield than non-inoculated field. AMF inoculants formulated with a blend of humic acids and seaweed extract produced significantly higher grain yield than the inoculants formulated with humic acids alone, in both the cultivation systems. Effect of AMF inoculation was highly pronounced in transplanted paddy than direct seeded paddy, resulted in highest grain yield, highest grain weight, better grain filling rate and highest tiller production. It can be concluded that AMF inoculants can be potentially used for rice cultivation under anaerobic water management system, both for direct seeded and transplanted paddy and the nature of biostimulants used in the formulation also play a key role in the efficacy of AMF inoculants. Our findings contribute to the growing global consensus that mycorrhizal inoculants could play a role in sustainable rice production systems of the future, when used appropriately.
