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.Keywords
Azospirillium, Phospho-Solubilizing, Bacterial Isolates, Nutrient Uptake, Salt Affected Soil.

The study was designed to isolate and characterize nutrient mobilizing soil microbes from salt affected soil of north Bihar. Out of 43 total 17 isolates of Azospirillium(12) and PSB (5) were selected in which, all the isolates produced one or the other different characteristics involved in plant growth promotion. They produced phytohormones like indole acetic acid, phospho-solubilization, siderophore and N2 fixation. The observations were made with 21 treatments. The experiments on rice were carried in Randomized Block Design with three replications. In the present investigation an attempt has been made to ascertain the effect of PGPR in different plant parameter such as tillers, effective tillers, plant height, panicle length, grain yield, straw yield and test weight.Keywords
