Soil can be turned to fertile by the usage of organic fertilizers. Among the organic fertilizers biofertilizers are one of the important components that make the soil healthy. Among the biofertilizers AM fungi is one of the important biofertilizer that form association with almost 80 percentage of plants (Harley and Harley, 1987). Its symbiotic association was well studied by several researchers (Rajasekaran and Nagarajan, 2004). AM fungi can uptake the International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 10 Number 01 (2021) Journal homepage: http://www.ijcmas.com Dual inoculation of AM fungi and Rhizobium is much essential for the leguminous plants to attain its maximum yield. Green gram is one among the pulses and considered to be an important pulse crop being a potential source of protein. A study was undertaken to enhance the growth and yield of green gram through efficient inoculation of AM fungi and Rhizobium. Different formulations were tested to evaluate the suitable one for green gram. AM fungi were applied as seed treatment and soil application along with water soluble formulation as well carrier based Rhizobium. The results revealed that the treatment that received both the biofertilizers were proven to be the best performer when compared to other treatments. Water soluble formulation of Rhizobium performed better with the soil and seed application of AM fungi in plant biometric observations, number of nodules, production of phosphatase enzyme etc. Hence the improved formulation performed better and reported to increase the yield of green gram.
