The demand for nitrogen (N) for crop production increased rapidly from the middle of the
twentieth century and is predicted to at least double by 2050 to satisfy the on-going …

Root exudates are an essential carrier for material cycling, energy exchange, and
information transfer between the belowground parts of plants and the soil. We synthesize …

Grain legumes are an important component of sustainable agri-food systems. They establish
symbiotic association with rhizobia and arbuscular mycorrhizal fungi, thus reducing the use …

Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance
plant growth by a wide variety of mechanisms like phosphate solubilization, siderophore …

Legumes obtain nitrogen from air through rhizobia residing in root nodules. Some species of
rhizobia can colonize cereals but do not fix nitrogen on them. Disabling native regulation …

Plant growth-promoting rhizobacteria (PGPR) are free-living bacteria which actively colonize
plant roots, exerting beneficial effects on plant development. The PGPR may (i) promote the …

Saline soils are a major issue for agriculture because salt turns agronomically useful lands
into unproductive areas. The United Nations Environment Program estimates that …

Use of Plant growth promoting rhizobacteria (PGPR) is a promising strategy to improve the
crop production under optimal or sub-optimal conditions. In the present study, five …

Numerous species of soil bacteria which flourish in the rhizosphere of plants, but which may
grow in, on, or around plant tissues, stimulate plant growth by a plethora of mechanisms …

Nitrogen and phosphorus are critical for the vegetation ecosystem and two of the most
insufficient nutrients in the soil. In agriculture practice, many chemical fertilizers are being …
