Abstract

Rhizobacteria (PGPR) that promote the plant growth are essential component of sustainable agriculture. Pea (Pisum sativum L.) root nodule Rhizobium leguminosarum bv. viciae ten strains were cultured at two different temperatures (28°C and 45°C).  Out of eight strains screened the three N25, N30 and N40 were temperature tolerant while only one strain (N40) showed tolerance to pH11. The growth of Rhizobium strain N40 at 45 °C was 96.8 percent as compared to the growth of the at 28°C. The temperature tolerant strain N40 produced maximum IAA and solubilized insoluble tri calcium phosphate compared to other strains and thus can be used microbial inoculant in biofertilizer technology.
