Ibrahim et al. (1990). VAM fungi inoculation significantly increased growth, photosynthetic rate, and stomatal conductance of sorghum plants under moderately dry soil conditions.

Saia et al. (2014). Field study in Sicily showing AM symbiosis mitigated drought stress in berseem clover, increasing total biomass, nitrogen content, and nitrogen fixation.

Genna et al. (1997). Turf inoculated with Glomus intraradices tolerated drought significantly longer, recovered from wilting faster, and maintained 29% higher chlorophyll levels than controls.

Combined study on berseem clover and mungbean. Mycorrhizal inoculation improved phosphorus uptake and cut the amount of water needed per gram of dry matter by half.
