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 grain and straw yield of rice respond significantly with the different treatment combination. The highest grain (85.0 q/ha) and straw yield (107.0q/ha) was obtained in) T₈ (100% RDF+ S₄₀+ Zn₅+Azotobacter). The treatment T₈ cause 55.96% increase in hybrid rice grain yield and 62.12% increase in straw yield over control. Quality characteristics of hybrid rice showed that the starch content, protein content in grain and head rice recovery increase with increasing nutrient doses and varied from 67 to 72%, 8.10 to 8.68% and 61 to 71% respectively. The treatment combination T₈ (100% RDF+ S₄₀+ Zn₅+Azotobacter), gave the best result in terms of yield and crop quality.
