The present study was aimed to study the efficiency of Pseudomonus putida 169 on few growth characters of Calotropis procera seedling under drought stress in greenhouse condition. The experiment was conducted as a completely randomized design with factorial arrangement and three replications. Experimental factors included two levels of inoculation (non-inoculated or control and Pseudomonus putida 169) and six levels of drought stress (with irrigation interval 3, 6, 9, 12, 15 and 18 days) in 6 months. The results indicated that most of aerial and ground organs of Calotropis seedlings significantly responded to inoculation under drought conditions. However, survival rate as well as height of non-inoculated and inoculated seedlings did not display prominent differences until irrigation period of 9 days. Up to irrigation interval of 9-days, there was not an outstanding reduction in amount of some growth parameters of non-inoculated seedlings compared with inoculated seedlings. From this investigation it is revealed that in more severe drought stress (9-days interval) rhizobacterium inoculation of Pseudomonus putida 169 induces to prevent from decrease of amount of some growth parameters. Thus, in order to achieve the suitable growth of Calotropis seedling together with cost reduction, it can be avoid applying the rhizobacterium inoculation of Pseudomonus putida 169 until 9-days irrigation.
