“…AMF+Rhizobium contributed positively to plant growth and yield in non-P nutrient-limited but low N conditions. The synergy of AMF and Rhizobium had been reported in previous studies in other legumes such as soybean (Glycine max) [57] and alfalfa (Medicago spp.) [6].…”

Arbuscular mycorrhizal fungi (AMF) and rhizobium play a significant role in plant symbiosis. However, their influence on the rhizosphere soil microbiome associated with nutrient acquisition and soil health is not well defined in the drylands of Montana (MT), USA. This study investigated the effect of microbial inoculants as seed treatment on pea yield, nutrient uptake, potential microbial functions, and rhizosphere soil microbial communities using high-throughput sequencing of 16S and ITS rRNA genes. The experiment was conducted under two contrasting dryland conditions with four treatments: control, single inoculation with AMF or Rhizobium, and dual inoculations of AMF and Rhizobium (AMF+Rhizobium). Our findings revealed that microbial inoculation efficacy was site-specific. AMF+Rhizobium synergistically increased grain yield at Sidney dryland field site (DFS) 2, while at Froid site, DFS 1, AMF improved plant resilience to acidic soil but contributed a marginal yield under non-nutrient limiting conditions. Across dryland sites, the plants’ microbial dependency on AMF+Rhizobium (12%) was higher than single inoculations of AMF (8%) or Rhizobium (4%) alone. Variations in microbial community structure and composition indicate a site-specific response to AMF and AMF+Rhizobium inoculants. Overall, site-specific factors significantly influenced plant nutrient uptake, microbial community dynamics, and functional potential. It underscores the need for tailored management strategies that consider site-specific characteristics to optimize benefits from microbial inoculation.

“…Furthermore, this approach has led to increased concentrations of available nitrogen and phosphorus in the soil compared to monoculture systems. Additionally, studies have indicated a positive correlation between the availability of phosphorus fertilizer and plant biomass [14]. These ndings underscore the importance of phosphorus management strategies in optimizing plant growth and maximizing agricultural productivity.…”

Incorporating bio-fertilizers, such as arbuscular mycorrhizal fungi (AMF), into mixed cropping systems has emerged as an innovative and sustainable approach to enhance crop growth and promote sustainable production. The study was conducted in two distinct locations within a mixed cropping system of corn and quinoa. Phosphorus fertilizer was applied at three different levels 50, 100, and 150 kg/ha while also considering the presence or absence of mycorrhiza. Cropping ratios included individual cultivation of quinoa, maize, and intercrop ratios of 50: 50, 75: 25, and 25: 75 (maize: quinoa). The utilization of phosphorus fertilizer improved the symbiotic interaction between plants and arbuscular mycorrhizal fungi, resulting in an increased rate of inoculation by AMF. The 50: 50 intercropping ratio, combined with the application of AMF, resulted in the highest contents of flavonoids, total phenolic compounds, tannins, saponin, antioxidant activity, and phytic acid in quinoa. Our findings demonstrated that AMF exhibit specific roles in optimizing plant strategies for phosphorus uptake and the efficient utilization of phosphorus in the mixed cropping. Recommending the application of AMF in a 50:50 intercropping ratio could be proposed to farmers as a friendly method to attain favorable phytochemical characteristics, particularly when using 50 kg/ha of phosphorus fertilizer.

“…Intercropping of soybean with maize and AMF inoculation signi cantly increased soybean and maize growth and improved availability of N and P concentrations in soil compared with soloculture. Also, results of some studies showed that the availability of phosphorus fertilizer is positively correlated with biomass of plant (Qin et al, 2023). Amani Machiani et al, 2022, showed that use of AMF increased secondary metabolites by increasing water and food elements and water uptake that also by improving the photosynthesis capacity and indirectly by stimulating pathways of biosynthetic through changes in signaling molecules phytohormonal amounts.…”

Using bio-fertilizers such as arbuscular mycorrhizal fungi (AMF) in mixed cropping systems is a new sustainable method for improving crop growth and phytochemical product. Two location field experiments were performed to evaluate the effects of three levels of phosphorus fertilizer: control, 50 kg ha-1, and 100 kg ha-1, and Arbuscular mycorrhiza fungi at two levels: M1 (no mycorrhiza) and M2 (use of mycorrhiza) on total phenolic, tannin, flavonoids, saponin compounds, The amount of antioxidant enzymes (CAT, POX, SOD), and phytic acid of quinoa in intercropping with maize. Different cropping ratios included quinoa mono culture and replacement intercrop ratios of 50:50, 75:25, and 25:75 (maize: quinoa). The results showed the treatments used significantly affected the biochemical traits of tannin, saponin, total phenolic compounds, antioxidant activity, and phytic acid in quinoa. According to our results, the quinoa phytochemical traits were affected by experimental treatments and increased significantly in intercropping patterns after applying phosphorus fertilizer and AMF. The highest amounts of flavonoids (66.80 mggr-1), TPC (40.57 mggr-1), tannin (0.49 mggr-1), saponin (14.2 mg of saponin per gram of dry feed), antioxidant activity (79.85%), and phytic acid (3.8%) of quinoa were achieved in a 50:50 intercropping ratio by use of AMF. In general, use of AMF in a cropping ratio of 50/50 proposed to approach for phytochemical characteristics such as phenolic component and antioxidant activity and phytic acid and reducing harmful compounds such as saponin in quinoa under the use of 50 kg ha-1 phosphorus fertilizer.
