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. Beneficial bacteria, particularly in the rhizosphere of plants, are deliberated and established to exert growth-promoting activities. These important rhizobacteria consist of the symbiotic Rhizobium species, few specific actinomycetes, mycorrhizal fungi and some free-living bacteria. Plant growth promoting rhizobacteria (PGPR) are a cluster of favorable bacteria which have the prospective for improving plant growth, development and yield. Research works on the effect of PGPR on medicinal plants are very limited. Accordingly, the present communication is dealt with the characterization of PGPR bacteria isolated from the rhizosphere of little explored medicinal herb, Celosia cristata L. The bacterium was identified as Pseudomonas aeruginosa (MCC 3198). Seed germination, seedling vigor, root length, shoot length, leaf count, dry and fresh weight, chlorophyll content and some defense enzymes of the plant C. cristata have significantly been improved as a result of application of this bacteria.
