A pot experiment was conducted to investigate the effect of soil microbes (Azospirillium and PSB) with different dose of NPK on salt affected soil properties, grain yield, straw yield, nutrient contain (%), uptake etc. the experiment was carried out in Randomized Block Design with 21 treatment and three level of fertilizer (50, 75 and100% recommended dose of NPK ha-1) with and without microbial isolates in three replication. The result indicate that the addition of microbial isolates to salt affected soil not only increase the yield of rice reduce use of fertilizer, improve the soil physico chemical properties like pH, EC, organic carbon, available N, available P and available K in the post-harvest soil as well enhance the rice quality.
