- Synergistic effects of Arbuscular mycorrhizal fungi and silicon on greenhouse tomato under drought stress across irrigation regimes (2026) · Scientific Reports · doi
The combined effects of AMF and Si under different irrigation regimes in greenhouse tomato remain insufficiently quantified. There is a need to evaluate the effects of AMF inoculation and Si application on yield, fruit quality parameters, and leaf nutrient composition.

Further studies are needed to investigate the effects of AMF and Si on other crop species. Future research should focus on developing more efficient water and fertilizer use strategies.
