Plant Growth Promoting Rhizospheric Bacillus spp. Isolated from Black Pepper (Piper nigrum L.)

Background: The rhizosphere contains many beneficial microorganisms which have a positive action on plant growth and development. In both natural controlled ecosystems, plant-associated bacteria play key role in supporting increasing health growth. Methods: this study, promoting Bacillus isolates associated with the of black pepper (Piper nigrum) were selected used for bioassay experiments host as well two test plants viz. French bean (Phaseolus vulgaris) Pea (Pisum sativum). Result: This investigation revealed that chosen study exert effect inoculated compared to uninoculated control. Molecular identification was done based 16S rRNA gene analysis. All four exerted considerable influence cuttings there is significant increase shoot height root length untreated cuttings. Seed bacterization resulted increment heavier fresh weight dry when control plants. Based these findings, it evident can be employed enhance not only but well. Hence, according could growth-promoting inoculants attain desired results stem seed bacterization.
