Coinoculation of symbiotic N-fixing rhizobia and plant growth-promoting Bacillus on legume seeds can increase crop productivity. We collected highly resolved data on coinoculation of rhizobia and bacilli on 11 grain legume crops: chickpea, common bean, cowpea, faba bean, groundnut, lentil, mung bean, pea, pigeon pea, soybean, and urad bean to verify the magnitude of additive effects of coinoculation in relation to single inoculation of rhizobia on plant growth and yield of grain legumes. Coinoculation of rhizobia and bacilli on legume seeds and/or soil during sowing significantly increased nodulation, nitrogenase activity, plant N and P contents, and shoot and root biomass, as well as the grain yield of most grain legumes studied. There were however a few instances where coinoculation decreased plant growth parameters. Therefore, coinoculation of rhizobia and Bacillus has the potential to increase the growth and productivity of grain legumes, and can be recommended as an environmental-friendly agricultural practice for increased crop yields.

Arbuscular mycorrhizal fungi (AMF) and rhizobia enhance the ability of crops to access nitrogen (N) and phosphorus (P) and are keystone microorganisms that engage in reciprocal interactions with plants. However, their contributions and impacts in alleviating plant nutrient dependency and mitigating N deposition and P limitation under various N and P additions remain unclear. We hypothesized that co-inoculation with AMF and rhizobia would synergistically enhance crop nutrient absorption and stabilize N:P stoichiometry for mitigating N deposition and P limitation and enhancing biomass.

Chickpea ( L.) is considered a cheap source of plant protein. In Mediterranean regions, and particularly in Tunisia, fungal attacks are likely to further aggravate drought stress and increase the economic vulnerability of chickpea production.

Maintaining a stable symbiotic relationship between rhizobia and soybeans is important in agriculture and ecosystems. However, cadmium (Cd) pollution disrupts this mutualism's delicate balance. We investigated the protective role of non-nitrogen-fixing bacteria on soybeans under Cd-induced stress.

Soil salinisation and concomitant soil degradation pose a major threat on plant performance and terrestrial ecosystem sustainability. Rhizobia and arbuscular mycorrhizal fungi (AMF) were reported to mitigate negative effects of adversity in their host plants. Here, we exposed two cultivars of Robinia seedlings (salt-tolerant cultivar Lu155 and salt-sensitive cultivar DB) inoculated with salt-tolerant and salt-sensitive rhizobia and/or AMF to salt treatment.

This study evaluates the impact of reinoculation and co-inoculation at different growth stages on the physiological quality of common bean seeds. A randomized block design was used, assessing germination, vigor, electrical conductivity, seedling length, and dry mass. Treatments T7 (co-inoculation + at R5) showed the highest germination rates, indicating enhanced seed viability.
