Ram Narayan Meena, Ashvin Kumar Meena * , Kamlesh Meena, Swathy Ullas and Sanjay Kumar Department of Agronomy, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi-221005, India *Corresponding author ABSTRACT Introduction Rice (Oryza sativa L.) provides more than half the daily food for one of every three persons in the world, especially for south-eastern Asia, where 90% of the world production of rice are grown and consumed. At global level, it occupies an area of about 163.51 million ha with production and productivity of 498.65 million tonnes and 4.55 tonnes/ha, respectively (USDA, 2018). India ranks first in respect of area 44.50 million ha second in production 115.63 million tonnes with average productivity 3.90 tonnes/ha (USDA, 2018). The burgeoning population pressure has forced many countries to use chemicals and fertilizers to increase the farm productivity for meeting their ever increasing food requirements. The prolonged and over usage of chemicals has, however, resulted in human and soil health hazards along with environmental pollution. Supplementation of entire N through FYM sustains crop productivity at much lower level. Since, the International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 11 (2019) Journal homepage: http://www.ijcmas.com A field experiment was conducted to evaluate the response of manurial treatment and bio inoculants on growth, yield and quality of rice at Agricultural Research Farm of Banaras Hindu University during kharif season of 2015. The experiment comprised four manurial treatment in main plot and four bio inoculants in sub plot. Experiment was laid out in split plot design and replicated thrice. The results indicated that significantly higher growth attribute, yield attribute and quality parameter of rice were recorded with the application of 50 % of RDN as FYM + 50% as vermicompost (MT-3). Among the bio inoculants treatments, PSB + Azotobacter/Rhizobium resulted in significantly higher growth, yield and quality parameters and remains at par with application of PSB.
