Abstract: A field experiment was conducted on Pot culture house of Department of Soil Science and Agricultural Chemistry at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the kharif season 2017, In the present experiment 9 treatments T1 (Control), T2 (100% RDF), T3 (100% RDF+ S40),T4 (100% RDF+Zn5), T5 (100% RDF+ Azotobacter), T6(100% RDF + S40+Azotobacter), T7 (100% RDF + Zn5+Azotobacter), T8 (100% RDF+ S40+ Zn5+Azotobacter), T9 (125% RDF), were laid out in Randomized Block Design(RBD) with four replication. Hybrid rice variety PHB-71 was taken for study. The results revealed that the N, P, K, S and Zn content in hybrid rice grain varies from 1.41 to 1.51 %, 0.35-0.39%, 0.35-0.45%, 0.20-0.25% and 15.0-18.5% mg/kg and the N, P, K, S and Zn content of rice straw varies from 0.21 to 0.29%, 0.17 to 0.24, 1.23 to 1.31%, 0.10 to 0.14% and 28.5-40.0 mg/kg respectively. The total uptake values of N, P, K, S and Zn varied from 90.70 to 159.38 kg/ha, 30.29 to 58.83 kg/ha, 100.25 to 161.42 kg/ha, 17.50 to 36.23 kg/ha and 269.85 to 585.25 g/ha. The maximum nutrient concentration and uptakes in case of all treatments was found in T8 (100% RDF+ S40 + Zn5 + Azotobacter) and lowest in T1 (Control).
