The field experiment was conducted on effects of PGPR on micronutrients availability in soil and its translocation in rice under loamy sand textured soil during kharif season of the year 2018 at Regional Research Station, Anand Agricultural University, Anand. The experiment was laid out in Randomized Block Design, comprising twelve treatment combinations of different levels of Fe and Zn with or without Bio NPK consortium (PGPR) with three replications. The soil of the experimental field was loamy sand in texture, low in organic carbon, medium in available nitrogen and phosphorus, high in available potassium and deficient in available Zn and Fe. The experimental results revealed that theapplication of RDF + 75% Zn + 75% Fe + Bio NPK consortium (T12) recorded significantly higher grain and straw yield, N uptake by straw, K uptake by grain, S uptake by grain and straw. Maximum Fe content in grain of rice recorded with the application of RDF + 75% Fe + Bio NPK consortium (T8). Whereas, in case of Fe content in straw and Zn content in grain and straw of rice, significantly higher with the application of RDF + 100% Zn + 100% Fe + Bio NPK consortium (T10). With respect to uptake, significantly higher Fe and Zn uptake by grain and straw, Mn uptake by straw and Cu uptake by grain of rice was observed with the application of RDF + 75% Zn + 75% Fe + Bio NPK consortium (T12). The soil available N, P2O5, K2O, S, Zn and Mn after harvest of rice crop were influenced due to different treatments but did not reach the level of significance. Maximum Azotobacter, Azospirillum, PSB and KMB population of soil was found in treatment T12 (RDF + 75% Zn + 75% Fe + Bio NPK consortium) over control. Thus, the beneficial effect of PGPR was observed to increase rice yield as well as Fe and Zn content in rice.
