“…The data confirmed that the stimulation of plant growth is not always related to the degree of AMF root colonization, as previously reported by Cavagnaro et al [46]. Earlier studies showed that the dual application of compost and AMF could have positive [13] or negative [3] effects on the levels of AMF root colonization. However, the mechanisms that underpin these effects remain to be elucidated [46].…”

“…In addition, the RhOL1 strain has the ability to produce indole-3-acetic acid (IAA), which might induce the modulation of the root architecture [59]. At the same time, AMF and compost have been shown to contribute to the stability of soil aggregates resulting in soil physicochemical and biological properties improvement, and hence a better root growth and nutrition [13,60]. Reports discussing the combined effect of AMF, rhizobia, and/or compost are very scanty, and it is worth noting that tripartite combination treatment mitigated the negative salinity impact more than their individual treatment.…”

“…Both mycorrhizal and rhizobial symbioses are known to increase tolerance to abiotic stresses in the host plants by modulating diverse mechanisms and improving their growth and productivity. It has been reported that the co-inoculation and co-culture of microbes could be more beneficial and enhance plant growth than a single-strain inoculation [13]. AMF improve nutrient and water uptake, increase photosynthetic rate, and induce the antioxidant system to prevent ROS damages [14,15].…”

Salinity is one of the devastating abiotic stresses that cause reductions in agricultural production. The increased salinization affects alfalfa growth, metabolism, and rhizobium capacity for symbiotic N2 fixation negatively. This study was undertaken to investigate the efficiency of green compost (C; made from green waste), arbuscular mycorrhizal fungi (M; field-sourced native consortium), and/or rhizobium (R; a salt-tolerant rhizobium strain) individually or in combination as an effective strategy to improve alfalfa productivity under non-saline and high-saline (120 mM NaCl) conditions. In addition, we aimed to understand the agro-physiological and metabolic basis as well as glomalin content in the soil of biofertilizers-induced salt tolerance in alfalfa. Here, we show that mycorrhizal infection was enhanced after MR inoculation, while C application decreased it significantly. Salinity reduced growth, physiological functioning, and protein concentration, but the antioxidant system has been activated. Application of the selected biofertilizers, especially C alone or combined with M and/or R improved alfalfa tolerance. The tri-combination CMR mitigated the negative effects of high salinity by stimulating plant growth, roots and nodules dry matters, mineral uptake (P, N, and K), antioxidant system, synthesis of compatible solutes, and soil glomalin content, sustaining photosynthesis-related performance and decreasing Na+ and Cl- accumulation, lipid peroxidation, H2O2 content, and electrolyte leakage.

“…; N, P and K% in the herb are presented in Table (9), in the present investigation, application of PGPR under irrigation rate of 1200 m 3 gave the highest effect on N, P and K% in rosemary plant in the 1 st and 2 nd cuts as well, using of biological fertilizer improved nutrient uptake and growth of rosemary under water stress. Our results suggest that the application of inoculation with AMF and PGPR could improve the defense against drought stress with overall produces positive outcomes of plant production mainly owing to the several nutrition-related benefits that this class of soil beneficial microbes can provide to their host-plants (Anli et al, 2020).…”

This study was carried out during the two successive growing seasons of 2018/2019 and 2019/2020 at the Farm of Ali Mubarak, South Tahrir, El-Bahira Governorate, Horticulture Research Station. Egypt, aiming to study the impact of some bio-fertilizers (Mycorrhiza, Algae, and PGPR) combined with 3 levels of irrigation (800, 1200, and 1600m 3 /fed treatments and their interactions on vegetative growth, essential oil %, essential oil components, N, P, K%, and proline content of rosemary (Rosmarinus officinalis L.) plant grown in a sandy soil. The obtained results could be summarized as follows; a significant increase in plant height, number of branches, and fresh and dry weights per plant were recorded with irrigation at 1200 m 3 /fed. On the other hand, the highest oil percentages and oil yield/ plant resulted under the effect of irrigation at 800 m 3 /fed biofertilizer treatments also, increased vegetative growth parameters i.e., plant height, number of branches, herb fresh and dry weights/ plant and oil percentage, and yield/plant. Irrigation at the rate of 1200 m 3 /fed, and PGPR alone or their combination resulted in the highest values of the above-mentioned traits (plant growth, parameters). However, the combination between irrigation at 800 m 3 /fed and PGPR showed the highest values of oil percentage and oil yield/plant. The N, P and K% in dried herb recorded their higher values with medium irrigation, i.e., at the rate 1200 m 3 in both cuts. Also, the results showed that there was a steady significant increase in proline content due to decreasing the irrigation rate. This investigation supports the application of naturallyoccurring plant growth promoting rhizobacteria (PGPR) and microorganism to advance plant development and sustainable option for farmers under deficit water to maximize the yield of rosemary plant.

“…Therefore, this study plays a vital role in increasing the efficiency of the use of nutrients. Previous research that reported the use of PGPR as biological fertilizer can be a biological control that can reduce the use of chemical fertilizers in crop production (Anli et al, 2020;Atieno et al, 2020). At this time, the use of intensive chemical fertilizers is one of the challenges in agriculture, reducing the application of nitrogen fertilizers without losing their performance (Bordoloi et al, 2019).…”

Sustainable agriculture requires nutrient management options that can increase crop yields that are profitable for N nutrient availability and are environmentally friendly. However, N nutrient is dynamic and easy to lose, and excessive use of chemical N fertilizers has a negative impact on the environment. Biofertilizer by rhizobacteria is an effective way to maintain a reliable N-supply for rice growth. This study investigates the effect of a different combination of rhizobacterial fertilizers on nitrogen ion concentration in the soil and total rice production. The field experiment was conducted in two seasons. There were three treatments, including PGPR with 25% CF, PGPR with 50% CF, and 100% CF. The soil sample was taken from each treatment in six growth stages of rice i.e. 15, 36, 50, 72, 100, and 118 days after transplanting. Soil chemicals NH 4 + and NO 3were analyzed by Ion Chromatography. The results showed that the uniformity of NH 4 + and NO 3 in the soil were the highest in fertilizer application with PGPR. The application of PGPR with 50% CF confirms that it can increase rice yields by 25.5% and 12.9%, respectively. The application of rhizobacteria can reduce the use of chemical fertilizers.
