In this study, 8 diazotrophic strains were isolated from rhizosphere soils and root nodules of legume and non-legume plants in Vietnam. Five of the eight isolates showed noticeable nitrogen fixation capability as determined via acetylene reduction assay, from 3.11 to 17.9 nmol/mL/h.

Biological control represents an important approach of agricultural biotechnology for controlling many fungal plant pathogens. Trichoderma spp. are the most promising and effective bioagents against many plant pathogenic fungi. In present paper, twenty Trichoderma isolates were isolated from chickpea rhizosphere soil and screened for their efficacy against soil borne plant pathogens namely R. bataticola, F. oxysporum ciceri and S. rolfsii. In chickpea the isolates ATPU 1, ATPP 6, KNN 4, KNO 2, KNPG 3 and KNP 1 were most efficient in the production of volatile and non-volatile compounds.

In the present study, 8 Actinomycetes were isolates from rhizospheric soil from Karanja (Lad) District wahism. Out of 8 Actinomycetes isolates, two isolates was found to be sensitive against all isolates and shows very excellent zone of inhibition. Antagonastic activity against human pathogens like, S. aureus, E. coli, P. aeruginosa and P. vulgaris, was also carried out. From the complete observation it was noticed that isolate N obtained from neem soil and H from Hibiscus soil is having excellent antagonistic activity in controlling all the test pathogens.

Soil is the habitat of one of the most complex of natural biological coin munities in which all the phenomena associated with the struggle for survival occur. This competition is greatly intensifies in the root zone of plants, the rhizosphere, owing to the greater density of its micro population. The Experiment was carried out in the in laboratory of Department of Environmental Science, SHUATS, Allahabad to study the effect of Modern agricultural practices on soil microbial properties of Chaka block of Allahabad district” U.P., INDIA in 2016.

Azospirillum is one of the versatile non-symbiotic, free living diazotrophic bacteria which appears to have a world-wide distribution and occurs in large number in the rhizosphere soil of a variety of grasses and cereals. The present study was carried out during Rabi and Kharif 2016-17 in the Department of Soil Science and Agricultural Chemistry, Birsa Agricultural University, Ranchi, Jharkhand. Efforts were made to screen out the presence of Azospirillum in rhizosphere of various non-leguminous crops and to characterize the isolates on the basis of morphological and cultural behaviours.

In modern agriculture there is a pivotal role of pesticides in pest management though, the side effect pesticides on soil biological system is non avoidable. Experimental result shows that imidacloprid recorded 21.42% increased azotobacter population while chlorpyrifos recorded 31.04% less azotobacter in comparison with untreated check. All the treatments showed negative impact on the rhizobium population and rate of growth inhibition was 30.81% to 55.18%; whereas the inhibition rate was ranged 22.08% to 54.37% in case of total bacteria population.

Diverse communities of beneficial plant growth promoting diazotrophs harbour in Rice rhizosphere which mostly plays a significant role in supplementing Biofertilizer, bioprotectant and bio stimulator and improves the crop productivity directly or indirectly. 53 rhizobacterial were isolated from lowland rice rhizosphere of Jorhat district of Assam in non-selective TSA media.

Rice crop harbours diverse beneficial plant growth promoting diazotrophs which mostly plays a significant role in supplementing not only N fertilizer but also gives indirect benefit to the crops by improving their productivity and immunity. Considering all the benefits from PGP diazotrophs, rice rhizospheric soil samples were collected randomly from 20 different locations of Jorhat district, Assam. Altogether, 53 rhizobacterial cultures were isolated in non-selective TSA media.

Tomato is affected by a large number of diseases. Among these, collars rot disease of tomato cause by S. rolfsii is a threatening disease in eastern coastal regions of Odisha. Since, this disease is soil borne in nature, it is very difficult to control by chemical fungicides. The native rhizosphere soil of tomato was used for isolation and screening of bacterial antagonists for their efficacy and growth promotion potential. A total of 54 bacterial isolates were isolated from rhizosphere of tomato of which five isolates viz.

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.

Contamination of agriculture land by heavy metals is a worldwide risk that has sped up noticeably since the beginning of the industrial revolution. Hence, there arise the demands of heavy metal tolerant plant growth promoting bacterial strains for specific metal contaminated agricultural sites restoration. In this study, 36 bacterial isolates were screened out from the rhizospheric soil of Phaseolus vulgaris.
