Abstract

 The present study was performed with the main objective of investigation of enhancement in the growth and antioxidant activity of Stevia rebaudiana, Bertoni, a medicinal plant and chief source of stevioside, natural sweetener. The whole experiment was followed by macro and micronutrients analysis of used soil for pot experiment. In the analysed concentration ratio; potassium was greater than and phosphorous. So, there was a need to dissolve these nutrients into the usable form; Paenibacillus polymyxa was selected due to having these characteristics. The results, observed in 0, 10 and 20 days, showed that in comparison to control, inoculation with experimented soil bacterium, considerably increased root and shoot length as well as no and size of leaves in plant. The positive impact of the performed experiments was obtained after 10 and 20 days respectively. Furthermore, antioxidant efficacy of S. rebaudiana was done using DPPH method which confirms the plant to be free radical scavenger. The conclusion of the experiment showed the efficacy of P. polymyxa on escalation of Stevia.
