The search for plant growth-promoting rhizobacteria (PGPRs) addresses the ongoing need new bioinoculants to be used on various agricultural crop species, including sugarcane. Bacterial strains were isolated from rhizosphere of sugarcane plants and identified by sequencing 16S ribosomal gene. main indole acetic acid producers Enterobacter sp. IP11, IP14, E. asburiae IP24. Achromobacter spanius I...

Nitrogen fixation is mainly responsible for improvement of crop yield. In this regard, diazotrophs like Rhizobium, Azotobacter and Azospirillum are important as they enrich nitrogen nutrition in N-deficient soils. Of these, Azotobacter promotes plant growth as well as nitrogen fixation. Thus technology has been developed for making use of Azotobacter biofertilizer for nitrogen and non-nitrogen ...

Rhizobacteria were isolated from the rhizoplane and rhizosphere of soybean plants from fields in Arkansas and tested for their effect on numbers of soybean cyst nematode (Heterodera glycines). In initial greenhouse tests in heat-treated silt loam soil, 138 of the 201 bacterial isolates tested had no influence on numbers of cysts and eggs + second-stage juveniles (J2) of H. glycines, 36 reduced ...

The rhizosphere supports the development and activity of a huge and diversified microbial community, including microorganisms capable to promote plant growth. Among the latter, plant growth-promoting rhizobacteria (PGPR) colonize roots of monocots and dicots, and enhance plant growth by direct and indirect mechanisms. Modification of root system architecture by PGPR implicates the production of...

Osmolytes, PGPR, Proline, Reducing Sugars, Total soluble sugars, Rhizobacteria ABSTRACT Free living rhizospheric bacteria from wheat rhizosphere have capability to produced plant growth promoting attributes under saline condition. The electrical conductivity (ECe) of saline soil samples from four different districts viz. Varanasi, Mau, Ballia and Ghazipur of Uttar PradeshIndia was 10.47 to 5.69...
