Abstract: 

Bhendi (Abelmoschus esculentus) belongs to family Malvaceae. It is most important vegetable crop. Which is grown throughout the tropical and sub tropical parts of the world. In the present study, soil samples were collected from ten different location in cuddalore district. The PGPR Organisms viz., Azospirillum, Pseudomonas, Azotobacter and Bacillus were isolated from ten different soil samples were purified and maintained for further studies. The selected PGPR isolates viz., AZS-3, PS-2 and AZO-4 were inoculated either individually and along with Bacillus BS-3and interaction effect of bhendi var. Arka anamika was studied under pot culture experiment. All the inoculation of PGPR Organism increased the growth and yield Parameter of bhendi when compared to uninoculated control. PGPR inoculation recorded the maximum vigour index of 1860 and germination percentage of 98.05%. It also recorded the highest plant height of 148.65cm and plant dry weight 21.8g plant-1. The yield Parameter such as number of fruits maximum 18 number Plant-1. fruit weight 18.5g Fruit-1 and fruit yield 126.51q/ha was recorded. It was confirmed that the interaction effect was more than microbial inoculation applied as a consortium than individual inoculation.
