The experiment has been done to assess soil fertility and increase the yield of rice production through Bio fertilizer. The plant height of rice variety Sarjoo-52 was significantly influenced by Azolla and N fertilizer. Bio-fertilizers like Azolla 0.2 kg/m2 + 50% N and P2O5, K2O recommended dose of paddy crop in T4 treatment plot is better response the other treatments plot. In this plot highest plant height 98.35 cm, number of tiller/hill 18 and grain yield 12.37% increase over all the treatment. Azolla increases the rice productivity but also improves the long term soil fertility and contributes 40-60 kg N/ha per rice crop. The value for soil N, soil OM, bulk density and porosity of the soil were found to be increased simultaneously for Azolla treatments. Application of Azolla enhances the soil nutrients availability by their biological activity in particular and helps build up the micro flora.
