The study examined how these arbuscular mycorrhizal fungi modulate growth parameters and key physiological responses under drought conditions. The findings provide a scientific basis for applying beneficial microbial associations to enhance drought tolerance in Aloe vera. To investigate the effect of water deficit and soil-based fungi inoculation on Aloe vera, a factorial experiment was conducted. Water deficit treatments included: field capacity (FC: 37.2 % volumetric water content (VWC), and irrigation at a weekly (16.5% VWC), and biweekly intervals (7.9 % VWC). Fungal treatments were Glomus intraradices and Glomus versi- forme. The experiment followed a completely randomized design in the research greenhouse of Azarbaijan Shahid Madani University, Iran, in 2024. The results showed that the co-treatments affected plant biomass, fresh and dry weight of gel, leaf length, and width, carotenoids content, H2O2, malondialdehyde, total soluble solids, proline, flavonoids, zinc and iron content, and catalase activity. Irrigation at FC and weekly interval + both fungi increased fresh and dry weight of the plant and gel, and leaf diameter a
