Efficiency of plant growth promoting rhizobacteria for the enhancement of Vigna mungo growth

Abstract

The rhizosphere soil of vigna mungo was collected and physicochemical parameter of the soil was studied. The plant growth promoting rhizobacteria were isolated and identified based on morphological and biochemical characteristics.The bacterial species were Pseudomonas fluorescens and Bacillus subtilis. The isolates were screened for phosphate solubilization and IAA producting ability was also measured. The PGP also characteristic such as catalase and siderosphore production was determined. The pot culture experiment was performed with PGPRs. From this,the phytochemical compounds such as chlorophyll, carbohydrate, flavonoids and phenol contents were determined from the leaves of Vigna mungo at 15d, 30d, 45d and 60 days interval.The role of PGPR as biofertilizers that exert beneficial effect on plant growth and development.
