Rice (Oryza sativa L.) is the most broadly consumed staple crop for almost half of the world’s population. Bioinoculants are the optimistic remedy for replacing chemical fertilizers and insecticides in crop production. Arbuscular mycorrhizal fungi (AMF) represent a vital group of root symbionts of higher plants, as they provide a range of soil nutrients (e.g. N and P) to plants in exchange for plant carbohydrates. A pot culture experiment was conducted to assess the effect of Glomus fasciculatum and zinc solubilizing bacteria on the growth and yield of rice var.CO-55 during the Kharif season in the pot culture yard of the Department of Agricultural Microbiology, Faculty of Agriculture, Annamalai Nagar, Tamil Nadu. The soil samples were collected from 15 different locations of the Coastal area, Cuddalore district. The results showed a significant improvement in soil biological indicators such as microbial population and enzyme activity due to application of (AM fungi) G. fasciculatum and zinc solubilizing bacteria along with graded levels of inorganic fertilizers. Further, AMF plants increase the allocation of N and P to rice panicles compared to non-AMF plants during the grain filling stage. The plant yield parameters as well as quality parameters were highest with this combination. The treatment, T10 (75 % NPK + Glomus fasciculatum + zinc Solubilizing Bacteria) was the most successful inoculation of rice among all the thirteen treatments and it significantly increased the growth and yield of rice variety CO-55 by enhancing the nutritional status, especially P and K status of the plants. Hence, this study recommends farmers to reduce the use of inorganic fertilizers by 25 %, when AM fungi and zinc Solubilizing Bacteria are used.
