摘要: Plant growth promoting rhizo bacteria (PGPR) are able to colonize all the ecological niches found on plant root and promotes growth, have profound effects productivity of plants. In this study total 163 isolates were successfully isolated from Jatropha curcas rhizosphere two distinctive sites Gujarat state (India).Ten screened basis their fast growing ability, motility examined for production in dole acetic acid (IAA),hydrogen cyanide (HCN), ammonia, exopolysaccharide (EPS)and phosphate solubilisation. DN2, DP3, DR1, SP1 SAz1 showed good potential ability promotion. They further studied different salt concentration, pH temperature.DN2, DP3 DR1 grown best at 0.5% NaCl and7 pH. shown maximum 1% 9 All five excellent under temperature 37°C. It is expected that inoculation with these &SP1 (Bacillusspp.), (Rhizobiumspp.) (Azotobacterspp.) positive impact root, shoot yield Jatrophacurcas field condition.
