Plant Growth Promoting Rhizobacteria (PGPR) is considered responsible for influencing plant growth by natural means. Understanding the role of PGR and PGPR in increasing the rooting ability of the cuttings, the isolated cultures of PGPR with better performance in comparison with PGR based combination were used for the present study and made as combination in media with different propositions. On comparison with IBA, PGPR based microbial strain had significantly greater rooting ability. Growth performance of acid lime cuttings had showed that the root length, shoot length and number of roots per plant were maximum in M₂S₅ of medium cuttings from microbial strain II of Bacillus spp. @ 2 per cent (IAA) at 90 DAP and the survival percentage was maximum in M₁S₅ of terminal cutting from microbial strains of Bacillus spp. @ 2 per cent (IAA) at 90 DAP. The study revealed that the medium cuttings treated with Microbial strain II @ 2 per cent media combination has given better result over the control which has greater advantage in nursery production of quality seedling, in a short span of time which is considered to be a challenging task.
