Generally microorganisms isolated from rhizospheric zone of plants have the congruency of high level phosphate solubilization (PS) and Plant Growth Promotion (PGP) for increase in crop production. In order to identify the swathe of rhizobacteria from rhizospheric zone of Lycopersicon esculentum, we used PYD and Bacillus isolation medium (BSM). Selected bacterial strain (AriD6A) showed good potential in PGP and PS. It was screened for PGP factors likes PS, Production of IAA, HCN and cell wall degrading enzyme. We also did genus level identification base on morphological and biochemical property of the isolated strain. In this work, we designed different types of regimen treatments. In this unique work we showed that AriD6A having a positive influence on Cicer arietinum L. in every treatment conditions with best performance. The isolate showed that seed germination of control (70.09-71.33%), treated (71.70-88.03%) and also shoot-root length as well as enhanced vigour index of C-SEO1: 1551.424, C-SEO2: 1626.008, SES1: (2310.68-3192.38), SES2: (2151.00-3202.00), SOS1: (2816.96-2968.35), SOS2: (2226.30-3057.37). Additionally, AriD6A solubilized phosphate at a concentration of 193.75 µg/ ml in PVK broth after 4 days of culturing and quantitative amount of IAA production was noted 46.30ppm. AriD6A could produce high level of HCN and SA good amount qualitatively. The biochemical test and characteristics suggest that AriD6A may belong to genus Bacillus. Overall study, lead us to suggesting the potentiality of isolate in PGP. This work can help in developing newer dimensions in PGP treatment and sustainable agriculture.
