Abstract

The intensive use of chemical fertilisers has reduced nutrient uptake efficiency in plants, mainly due to salinisation. This effect has prompted the investigation of alternative forms of plant nutrient management. One of the promising solutions to this is the use of microbial inoculants, specifically arbuscular mycorrhizal fungi and the plant growth-promoting rhizobacteria (PGPR). This systematic review, conducted in accordance with PRISMA 2020 guidelines, analysed 36 peer-reviewed studies published between 2008 and 2025 across 18 countries to assess the effects of inoculation with arbuscular mycorrhizal fungi (AMF), both alone and in combination with plant growth-promoting rhizobacteria (PGPR), on maize growth, physiology, and biochemical responses. The main finding was that soil P availability was the primary factor determining whether inoculation was successful. This was especially noted in soils with soil-available P of less than 17 mg P kg−1 of soil. Soil texture and pH also played key roles in both single AMF inoculation and dual AMF-PGPR inoculation. Several studies showed that dual inoculation improved maize stress tolerance by coordinating antioxidant activity, osmotic balance, and hormonal signalling, rather than through simple additive growth effects. Overall, the findings suggest that AMF-based inoculation is most effective when applied strategically in reduced-input, phosphorus-limited, or drought-prone maize systems, rather than as a universal solution. These results support targeting inoculation toward resource-constrained systems where returns are most likely, especially P-deficient soils.
