Improved seeds and inorganic sources of fertilizer application are the core techniques of green revolution to reach the potential yield. Application of bio-fertilizer would improve the physical, chemical and biological condition of the soil, The recent concept of integrated nutrient management with the use of biofertilizer acquired greater importance not only for the increased yield, but also for farmers profit maximization and contribution to environment preservation. In this context the experiments were conducted to study the response of hybrid rice ADTRH1 with biofertilizers viz., Azospirillum, phosphobacteria and Methylobacterium, compared with GA3 spraying at different level of chemical fertilizer application. Results revealed that microbial consortia at 100 % recommended levels of NPK fertilizer application with pink pigmented facultative methylotrophic bacteria (PPFM) foliar spray recorded maximum growth, germination percentage (95.81 %) and yield of hybrid rice (7627 kg/ha) over other treatments and uninoculated control.
