Abstract

In the present study, phosphate solubilizing rhizobacterial isolate STJP from the rhizosphere of was identified as a sp. on the basis of phenotypic, biochemical, and 16S rRNA gene sequencing. In addition to phosphate solubilization ability, isolate sp. STJP produced a significant quantity of siderophore (16.06 µg/ml) and indole 3-acetic acid (30.59 µg/ml). In the greenhouse experiment, treatment with STJP along with tricalcium phosphate (TCP) showed significant increase in the plant growth parameters, oil yield and P uptake in as compared to the control plants. Amongst all the treatments, highest oil yield and menthol content were observed when treated with sp. STJP + TCP. Hence, an integrated approach of using sp. STJP along with TCP can be used to increase the production of menthol and oil yield of . This approach of using fertilizer along with phosphate solubilizing sp. worked very well and was more effective in comparison with individual treatment of fertilizer or plant growth promoting rhizobacteria. A combined use of efficient phosphate solubilising bacteria loaded with plant growth promoting characters along with TCP can thus be far effective way for enhancing the yield of crops in a sustainable manner.
