“…Besides, it contains sugars, dietary fibers, starch, minerals, vitamins and essential amino acids (1,2). Interestingly, leguminous pulse crops including blackgram sustain their growth by establishing a symbiotic association with Rhizobium, which fix atmospheric nitrogen in the root nodules (3)(4)(5)(6)(7). In addition to Rhizobium, AM fungi also form a symbiotic association with leguminous crops (8).…”

Arbuscular mycorrhizal (AM) fungi are well known symbiotic microorganism found to improve the growth of host plant by mobilizing immobile nutrients, mainly phosphorus, from the soil. However, the effect of AM fungi on host plant growth depends on the percentage mycorrhizal colonization, whereas it is not clear that the percent mycorrhization impacts by AM fungal spore abundance of the inoculum. Therefore, the current investigation was conducted to know the effect of percent mycorrhization of Glomus intraradices on the growth of blackgram inoculated with varied numbers of AM fungal spores via seed biotization (1 to 10 AM fungal spores per seed). Percent mycorrhizal colonization and plant growth characteristics of blackgram were recorded after 10, 20 and 30 days of sowing (DOS). Our results are revealed that the percentage of mycorrhizal colonization significantly influenced based on the availability of AM fungal spore richness of the biotized seeds, which leads to altered crop growth. Percent mycorrhizal colonization in the roots of blackgram increased with increasing AM fungal spore abundance per seed and it ranges from 10 to 70 %. Moreover, mycorrhizal colonized plants recorded higher shoot and root length, leaf area, leaf area index, shoot and root biomass production as well as chlorophyll content over control, conversely it was increased further with increasing percent mycorrhizal colonization, which is directly proportional to the richness of the AM fungal spores per seed. Therefore, AM fungal spore abundance is one of the governing factors that influence percent mycorrhizal colonization in roots of plants besides AM fungal and plant species and soil condition.

“…The existence of these microbes also has some influence on the dynamics between plant and soil rhizosphere available N and P pools. For instance, Rhizobium strains fix atmospheric N by forming nodules and contribute to soil fertility and crop yield as biologically fixed N is more sustainable and less prone to volatilization and leaching loss [ 34 , 67 ]. Also, Basu et al [ 68 ] opined that N-fixing bacteria and PSM enhances plant growth and yield by providing nutrients without additional chemical fertilizer input.…”

Crop production encounters challenges due to the dearth of nitrogen (N) and phosphorus (P), while excessive chemical fertilizer use causes environmental hazards. The use of N-fixing microbes and P-solubilizing microbes (PSMs) can be a sustainable strategy to overcome these problems. Here, we conducted a greenhouse pot experiment following a completely randomized blocked design to elucidate the influence of co-inoculating N-fixing bacteria (Bradyrhizobium japonicum) and PSMs (Saccharomyces cerevisiae and Saccharomyces exiguus) on atmospheric N2-fixation, growth, and yield. The results indicate a significant influence of interaction on Indole-3-acetic acid production, P solubilization, seedling germination, and growth. It was also found that atmospheric N2-fixation, nodule number per plant, nodule dry weight, straw, and root dry weight per plant at different growth stages were significantly increased under dual inoculation treatments relative to single inoculation or no inoculation treatment. Increased seed yield and N and P accumulation were also noticed under co-inoculation treatments. Soil available N was highest under sole bacterial inoculation and lowest under the control treatment, while soil available P was highest under co-inoculation treatments and lowest under the control treatment. We demonstrated that the co-inoculation of N-fixing bacteria and PSMs enhances P bioavailability and atmospheric N2-fixation in soybeans leading to improved soil fertility, raising crop yields, and promoting sustainable agriculture.

“…Sesbania plants and their associated rhizobia are advantageous because they can adapt to acidic, alkaline and waterlogged soil conditions (Evans & Rotar, 2020). Seven unique genospecies of Agrobacterium , Ensifer , Neorhizobium and Rhizobium were identified among the Sesbania cannabina rhizobia, and they were all characterized as symbiovar sesbaniae due to their highly conserved symbiosis genes and nodulation test results (Cummings et al, 2009; Sindhu et al, 2019). Several Sesbania plant rhizobia capable of tolerating extreme conditions of alkalinity, acidity, salinity, drought, metal toxicity and fertilizer were identified.…”

The rhizosphere is the region around the plant roots where maximum microbial activities occur. In the rhizosphere, microorganisms' beneficial and harmful activities affect plant growth and development. The mutualistic rhizospheric bacteria which improve plant growth and health are known as plant growth-promoting rhizobacteria (PGPR). They are very important due to their ability to help the plant in diverse ways.
