Plant Growth-Promoting Rhizobacteria (PGPR) are naturally occurring soil bacteria that can enhance plant growth by wide variety of mechanisms. PGPR offers an attractive way to replace chemical fertilizer, pesticides, and supplements. Agriculture and horticulture crops inoculated with certain PGPR strains may result in multiple effect right from enhancement of seedling germination to vegetative growth to yield.

Replant disease is a major problem of apple orchards, which is a main cash crop in TransHimalayan region. The cause of this replant problem includes both biotic and abiotic factors, such as low nutrients, phytotoxins, actinomycetes, fungal complexes and nematodes. Fungi and oomycetes belonging to the well-known root rot complex are important factor of replant problems in apple.

Plant growth promoting Rhizobacteria (PGPR) enhance the plant growth and productivity through wide variety of mechanism. The strains isolated from rhizosphere of Momordica charantia, mainly belonged to Bacillus, Azotobacter, Pseudomonas and Acinetobacter. Nearly 50% isolates of Pseudomonas and Acinetobacter and all the isolates of Bacillus and Azotobacter were able to solubilise tricalcium phosphate.

Both biotic and abiotic stresses are major constrains to agricultural production. Under stress conditions, plant growth is affected by a number of factors such as hormonal and nutritional imbalance, ion toxicity, physiological disorders, susceptibility to diseases, etc. Plant growth under stress conditions may be enhanced by the application of microbial inoculation including plant growth promoting rhizobacteria (PGPR).

The present experiment was conducted at Hi-tech greenhouse of Precision farming development center of the Department of Horticulture, CCS Haryana Agricultural University, Hisar (Haryana) during the year 2016-17 and 2017-18.Strawberry plants were inoculated with different strains of Pseudomonas and plants inoculated with Pseudomonas strains fertilized with 75% RDF. It was observed that maximum number of runner per plant was recorded in plants fertilized with 100% RDF, however number of runner per plant increased with the application of rhizobacterial strains as compared to control, i.e.

Plant growth promoting rhizobacteria (PGPR) are beneficial bacteria that colonize plant roots and enhance plant growth by a wide variety of mechanisms. The isolate of PGPR designated as Pseudomonas aeruginosa strain (2CpS1) was successfully isolated from the soil and rhizosphere of roots of plants growing in fields, Almora district.

Elite strains of plant growth promoting rhizobacteria were proficiently selected based on the strategic screening approaches. These included in vitro testing for plant growth promotion attributes, seedling bioassay under controlled and under greenhouse conditions. A total of 483 morphologically distinct bacteria [156 rhizosphere fluorescent Pseudomonas spp. (RSF), 206 rhizosphere Bacillus spp. (RSB) and 121 endophytic Bacillus spp. (EB)] were isolated from the roots and rhizosphere soil of coconut palms growing in different states of India.

Soil microorganisms, that flourish in, on or around plant rhizosphere, have tremendous potential to stimulate plant growth by plethora of mechanisms. In this study, 40 rhizobacterial isolates from 15 mung bean rhizospheric soil samples were morphologically and biochemically analysed and tentatively assumed to belong to genera Bacillus (35%), Pseudomonas (55%) and Rhizobium (10%). Ten isolates were evaluated of plant growth promoting (PGP) traits at 35°C viz. production of IAA, GA (Gibberellic acid), flavonoid and siderophore as well as Zn and P solubilisation.

Stress tolerant Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth under stress condition. In our present study, 32 stress tolerant PGPR strains (8 Rhizobium. 8 Pseudomonas, 8 KRB, 8ZSB) were isolated from the rhizosphere soils of blackgram crop and screened for their ACC deaminase and Exopolysaccharide (EPS) production. Out of 32 isolates four isolates (1 Rhizobium. 1 Pseudomonas, 1 KRB, 1 ZSB) were selected on the basis of their ACC deaminase activity and Exopolysaccharide production.

In Groundnut aflatoxin contamination is a major problem which affects the quality of the seed. These aflatoxins have carcinogenic, hepatotoxic, teratogenic and immunosuppressive effects which were produced by Aspergillus flavus and A. parasiticus. For the management of aflatoxin problem in groundnut, use of plant growth-promoting rhizobacteria (PGPR) is a viable and sustainable option. Our present study is aimed at determining the mode of action of these PGPR (Pseudomonas fluorescens) using Scanning Electron Microscope (SEM). A superior P.

A total of forty rhizosphere soil samples were collected from different locations of Bengaluru urban district, Karnataka and used for isolation of PGPRs by standard dilution plate method. Seventy bacterial isolates were selected, purified and were examined for morphological characters like colony morphology, cell shape, Gram reaction. Isolates were diverse in their morphology ranging from dull to milky white, rough to smooth margins, viscous, small to large, non-spreading and spreading.

Conservative methods of harvest propagation to develop expansion and yield of vegetation underneath in diverse ecological threats are lengthy and not triumphant in many cases. Use of expensive injurious agrochemicals and pesticides causes stern danger to environment and renders growth of challenging pathogens. At present time, more and more attention has been made towards cost-effective and environment-friendly alternatives to improve natural wealth and assist plant development.

Use of biocontrol agent to increase the growth of crop has been an alternative source to meet the demand of growing population. Plant growth promoting rhizobacteria (PGPR) are the soil bacteria inhabiting around/on the root surface and are directly or indirectly involved in promoting plant growth and development via production and secretion of various regulatory chemicals in the locality of rhizosphere. These bacteria competitively colonize the roots of plants and can act as biofertilizers and/or antagonist (biopesticides) or simultaneously both.
