“…Fe metabolism is of importance in nodules since this metal is a constituent of key proteins such as nitrogenase and leghemoglobin (Moreau et al, 1995). The increments in plant growth parameters due to application of inoculum with AMF might be attributed to the enhancing of nutrients uptake, increment in nitrogen fixation, phosphate solubilization and synthesis of phytohormones as reported by previous research work (Al-Karaki 2017;Sathiyadash et al 2017;Pereira et al, 2019). These results might be due to Fe roles in contributing to other nutrients in increasing plant growth.…”

The experiment was run for two successive growing winter seasons during 2016-2018. The synergistic effects of Arbuscular mycorrhizal fungi (AMF) inoculation and foliar iron fertilizer on plant growth and yield parameters of broad bean plant (Vicia faba L.), grown in sandy loam soil, were conducted. Mycorrhizal colonization and their spore intensity, nodule formation and their number were also investigated. Two mycorrhizal treatments (Inoculum AMF and native AMF) and five foliar Fe-concentrations (0.0, 300, 400, 500 and 600 ppm) were applied. The interaction between different categories of AMF and foliar Fefertilization was also evaluated. The results obtained revealed that the application of inoculated AMF and spray with Fe at 400 ppm increased spore count and root colonization. However, total number of active nodules/plant increased with inoculated AMF and spraying iron at 600 ppm. Results indicated the superiority interaction treatment of inoculated AMF with the foliar Fe at the concentration of 400 ppm and/or 500 ppm by which it recorded the highest values of plant growth traits; viz, root length, number of branches/plant, total dry weight/plant and photosynthetic pigments content in both seasons. Moreover, the same treatment recorded the highest values with all pod characters and yield, except weight of number of green seeds/pod in first season and average pod weight (g) in the second one.

“…Significant growth promotion effects of AM fungi, i.e., enhanced growth of seedlings in nurseries and improved performance after planting in the field [13,14] improved stand establishment rate and enhanced plant resistance to soil salinity immediately after transplanting [15,16], and increased root and shoot dry matter [14], are reported in various vegetable crops. Similarly, growth-promoting capabilities of bacteria such as; nitrogen fixation, phosphate solubilization, iron sequestration, synthesis of phytohormones, modulation of plant ethylene levels ( [17,18] are also largely documented.…”

“…In agreement with previously reported increased beneficial aspects of the association of mycorrhizae fungi and Rhizobium sp., with pulse crops [40], we found that combined application of AM fungi (Rhizophagus irregularis + Claroideoglomus claroideum) and N-fixing bacteria (Rhizobium leguminosarum) were able to maintain average grain weight at the level of non-saline plants and having significantly higher yield than control plants. Improved plant nutrition due to the presence of AM fungi [14,41] and facilitation of the acquisition of nutrient resources or the alteration of plant hormone levels by root-colonizing bacteria [30,42,43], should be the reasons for better vegetation and highest yield in dually inoculated plants. Even though it was significantly less than AMF + Rh.l variant, the AMF + Brh combination and single application of Rhizophagus irregularis and Burkholderia were capable of providing significantly higher yields than the control plants.…”

This study investigated the effects of specific strains of two arbuscular mycorrhizae fungi (AMF) (Rhizophagus irregularis and Claroideoglomus claroideum) and of two plant growth-promoting bacteria (PGPB) (Rhizobium leguminosarum and Burkholderia spp.), supplied either individually or as combination of a mixture of both arbuscular mycorrhizae fungi with each bacteria on root morphology, growth and fresh grain yield in pea (Pisum sativum L.) plants. Inoculated and non-inoculated pea plants were subjected to two levels of salinity (0 and 50 mM) by the addition of sodium chloride into tap water. Prior to fresh grain harvesting the morphology of root system was analyzed and the dry matter of roots and shoots were individually measured in randomly selected plants. Fresh pods were individually harvested per each plant; fresh (green) grains were separately counted and weighted per each pod at each individual plant, and the average grain weight was calculated by dividing total grain weight of plant with the respective number of green grains. The raise of salinity in the irrigation water strongly diminished the growth of pea plants by significantly reducing weight, length, surface area and root volume of pea plants. The relationships of pea plants with beneficiary fungi and bacteria were specific to each microorganism and highly depended on the environment. We found that under saline conditions, Rhizophagus irregularis provided a better vegetative growth and a higher yield than Claroideoglomus claroideum. Although, single application of Burkolderia spp. provides a better vegetative growth than single application of Rhizobium leguminosarum the best results, in terms of growth and harvested yield, were still obtained by combined application of AM fungi with Rhizobium leguminosarum. This combination was able to sustain the average grain weight at the level of non-saline plants and provided a significantly higher yield than the control plants.

“…The synergistic behavior of bio-inoculants and R. intraradices was also corroborated by maximum increase in TKN and AVP level of treatments BMRIV, RIV, PMRIV and ACRIV (bio- (Table 1). Congruent to this study, Al-Karaki [42], showed that AM fungi had a positive influence on the composition of mineral nutrients (particularly immobilized nutrients such as P) of plants under salt stress conditions.…”

Restoration of salt-affected soil through cultivation Chrysopogon zizanioides is a promising approach. The two way benefit of such an approach is that reclamation of salt-affected soil concomitant to improve plant growth and increased yield of essential oil produced in the plants roots. Earlier studies showed physiological changes and reduced growth of C. zizanioides under salinity. In the present study, plant growth promoting microorganisms viz. Pseudomonas monteilii, Bacillus megaterium, Azotobacter chroococcum and Rhizophagus intraradices were used as bio-inoculants for cultivation of C. zizanioides under saltaffected soil. Bio-inoculants in combination with vermicompost significantly increased the growth and productivity of C. zizanioides under salt-affected soil, and simultaneously improved soil health. When compared to control, the soil physico-chemical and biological properties of bio-inoculants treated plants was significantly improved. The reclamation of salt-affected soil was evident by the significant decrease in the level of soil pH (11.0%), electrical conductivity (23.5%), sodium adsorption ratio (15.3%), and exchangeable sodium percent (12.4%) of bio-inoculants treated plants. The improvement of soil cation exchange capacity indicated the decrease in soil salinity. Whereas increase in the microbial count (four-fold), AMF spores (447 spores), dehydrogenase (six-fold), acid (twofold) and alkaline phosphatase (five-fold) activities in rhizosphere soil of bio-inoculant treated plants indicated the improved biological properties. A positive correlation of plant biomass production to soil organic carbon, total Kjeldahl nitrogen, available phosphorus and cation exchange capacity depicted improved nutrients content in rhizosphere soil of bio-inoculant treated plants. The findings of this study suggest that P. monteilii and R. intraradices with vermicompost can be effectively used as bio-inoculants for encouragement of phytoremediation in salt-affected soil.
