ABSTRACT
Soil management today is dominated by toxic chemical fertilizers that pose a serious health and environmental risk. Beneficial soil microbes play a promising role in sustainable
agriculture when used as biofertilizers. Pigeonpea (Cajanus cajan) is an ancient protein-rich leguminous pulse in India. Twelve different locations in Punjab (India) provided
rhizospheric soil samples and the growth rates of 35 isolates were assessed at various temperatures. To identify potential plant growthpromoting traits with antifungal properties,
morphological and biochemical characterization were carried out. Compared to uninoculated pigeonpea seeds, inoculated seeds with rhizoisolates showed a significant increase in
rowth parameters in greenhouse pot conditions. Plant growth-promoting rhizobacteria (PGPRs) are a good way to increase crop yields while also controlling disease outbreaks.
Key words : Antagonistic, Antifungal, PGPRs, Pigeonpea, Rhizobacteria.
