Phosphate-solubilizing Bacillus sp. enhances growth, phosphorus uptake and oil yield of Mentha arvensis L.

ABSTRACT: In the present study, phosphate solubilizing rhizobacterial isolate STJP from the rhizosphere of Stevia rebaudiana was identified as a Bacillus sp. on the basis of phenotypic, biochemical, and 16S rRNA gene sequencing. In addition to phosphate solubilization ability, isolate Bacillus 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 (TCP²⁰⁰) showed significant increase in the plant growth parameters, oil yield and P uptake in M. arvensis as compared to the control plants. Amongst all the treatments, highest oil yield and menthol content were observed when treated with Bacillus sp. STJP + TCP²⁰⁰
