Abstract
In the present investigation, soil samples of Capparis decidua L., Calligonum polygonoides L., Cuminum cyminum Gmel. were taken from different areas of Rajasthan. The bacterial isolates were evaluated for their plant growth promoting rhizobacterial (PGPR) activity, by nitrogen fixation and phosphate solubilization activity. K3, P40, C63, and C79 were the isolates that showed both activities and C63 and C79 showed very good response among all the isolates selected for each plant species. These PGPR may serve as bioinoculants to increase availability and uptake of mineral nutrients for plants and stimulate growth of plants in arid soils of Rajasthan. Rhizobacterial isolates from C. cyminum C63, C68, and C60 showed positive PGPR activity i.e., increased root and shoot length, mean wet biomass, and percent germination.
