| The effect of bacteria(Azospirillum lipoferum and Pseudomonas putida) were examined in a green house pot experiment with Aloe vera. The present study was carried out in the complete randomized block design with 4 treatments and 3 replications. The treatments included(1-control plants2-inoculation with Azospirillum lipoferum 3-inoculation with Pseudomonas putida and4- inoculation with mixture of microorganisms). The statistical analysis showed the Plant growth promoting rhizobacterias (PGPR) that tested in this experiment had significant effect on increasing growth parameters such as roots and leaves fresh and dry weight ,number and length of leaves and roots ,leaf area as well as the content of the P and K uptake in Aloe vera . High significant difference was observed in inoculation of Pseudomonas putida. This treatment significantly increased yield about 42.4% compared with control plants. The results obtained in the present work mainly show the potential of PGPR in production of Aloe vera. |
