“…Present study is in agreement with the findings of Mosse and Bowen [40], Read et al [41], Prasad [21], Prasad and Gautam [42] and Pringle et al, [43] Prasad [21] reported a range of 5-370 spores/100g dried soil in India. Comparatively a low spore density like this present study might have been caused by a warmer climate inserting less pressure for sporulation [44] which supports the findings of Nadarajah and Nawawi [45][46][47] and Prasad [21]. The present study reveals that AM fungi are quite common in most of the vegetable species examined from various places in the arid zones of Rajasthan, India with species of Glomus found to be widely spread among the vegetable of this region.…”

An investigation was carried out for twenty-two plant species, cultivated widely as vegetable crops in arid region of Rajasthan, state of India belonged to eight different families to measure their affinity in harbouring symbiotic association with arbuscular mycorrhizal fungi (AM fungi) and nutrient status in rhizospheric soil. Twenty out of the twenty two species were having developed AM fungal colonization in their root tissues with a range of 16.33% to 91.33%. All the soil samples tested were slightly acidic to alkaline and housed AM fungal spore with a density ranges from 80.33-199 spores/ 50g air dried soil. The AM fungal spore density in the soil was not found to have any effect on symbiotic colonization in root tissues of studied vegetable crop plants by Mycorrhizae. The soil chemical analysis was also noticed to have no correlation with both colonization of root tissues by AM fungi and spore densities in the rhizospheric soil. Variations in AM fungal root colonization's and spore densities were found statistically significant. Plant species had a significant role in root tissue colonization by AM fungi.

“…AM symbiosis could be altered by the level of soil available P, and mutualism likely occur in P-deficient soils ( Johnson et al., 2015 ). In the results of Liu et al. (2020) , AMF colonization rate was the highest in P30 treatment compared with the control and P100 treatments.…”

In the results of Liu et al (2020), AMF colonization rate was the highest in P30 treatment compared with the control and P100 treatments. In the present study, both AMF colonization rate and P content were the highest in P20 treatment, likely indicating the best benefit of AM symbiosis (Sawers et al, 2017).…”

Selenium (Se) is a beneficial element to plants and an essential element to humans. Colonization by arbuscular mycorrhizal fungi (AMF) and supply of phosphorus (P) fertilizer may affect the bioavailability of Se in soils and the absorption of Se by plants. To investigate the interaction between AMF and P fertilizer on the transformation of soil Se fractions and the availability of Se in the rhizosphere of alfalfa, we conducted a pot experiment to grow alfalfa in a loessial soil with three P levels (0, 5, and 20 mg kg-1) and two mycorrhizal inoculation treatments (without mycorrhizal inoculation [−AMF] and with mycorrhizal inoculation [+AMF]), and the interaction between the two factors was estimated with two-way ANOVA. The soil in all pots was supplied with Se (Na 2 SeO 3) at 1 mg kg-1. In our results, shoot Se concentration decreased, but plant Se content increased significantly as P level increased and had a significant positive correlation with AMF colonization rate. The amount of total carboxylates in the rhizosphere was strongly affected by AMF. The amounts of rhizosphere carboxylates and alkaline phosphatase activity in the +AMF and 0P treatments were significantly higher than those in other treatments. The concentration of exchangeable-Se in rhizosphere soil had a positive correlation with carboxylates. We speculated that rhizosphere carboxylates promoted the transformation of stable Se (iron oxide-bound Se) into available Se forms, i.e. exchangeable Se and soluble Se. Colonization by AMF and low P availability stimulated alfalfa roots to release more carboxylates and alkaline phosphatase. AMF and P fertilizer affected the transformation of soil Se fractions in the rhizosphere of alfalfa.

“…Mycorrhizae colonization was significantly decreased fertilizer input by 100 mg P kg −1 ; and a combination of mycorrhizae fungi, biochar and P fertilizer significantly increased shoot biomass in polluted soils and the growth of chili in sandy soil (Putra et al, 2020). Liu et al (2020) reported that in cadmium (Cd)polluted soils, treatment with no biochar and P input had a positive mycorrhizae response, but treatment with biochar or high-P input had a negative mycorrhizae response.…”

Agricultural constraints on sandy soil are poor chemical characteristics and low biological activity resulting in the soil becoming less productive to be planted. One of the efforts to improve the quality of sandy soil are application of mycorrhizae and a soil ameliorant. The purpose of this study was to determine the effect of mycorrhizae and a soil ameliorant on soil chemical characteristics and soil biological activity. The experiment was arranged using a Complete Randomized Design that had two factors. The first factor (1) was mycorrhizae dose, without mycorrhizae (M0) and six spores of mycorrhizae/plant (M1), and the second factor (2) was types of soil ameliorant, without ameliorant (S0), cow dung (S1), rock phosphate (S2), biochar (S3), cow dung–rock phosphate (S4), cow dung–biochar (S5), and rock phosphate–biochar (S6). The results indicated that combination of six spores mycorrhizae/plant–cow dung 60 tons ha−1–biochar 25 tons ha−1 (M1S5) increased soil organic carbon (SOC) (235%), available P (675%), cation exchange capacity (CEC) (216%), total glomalin (101%), and easily extracted glomalin (69%), decreased exchangeable sodium percentage (66%), and increased absolutely for root infection and spore density than without mycorrhizae and a soil ameliorant (control). The lowest of SOC in non-mycorrhizae and rock phosphate, available P, CEC, root infection, spore density were found on the control, but the lowest of total glomalin and easily extracted glomalin were found on non-mycorrhizae–rock phosphate. The application of mycorrhizae, cow dung, and biochar improved the sandy soil characteristics.
