Abstract:
A field experiment was conducted at student’s instructional farm Chandra Shekhar Azad University of Agriculture & Technology, Kanpur during Kharif season of 2019 and 2020. The experiment was carried out in Factorial Randomized Block Design (RBD) having three replications and sixteen treatments T₁ (control), T₂ (Zn₀₊S₁₅), T₃ (Zn₀₊S₃₀), T₄ (Zn₀₊S₄₅), T₅ (Zn_2.5+S₀), T₆ (Zn_2.5+S₁₅), T₇ (Zn_2.5+S₃₀), T₈ (Zn_2.5+S₄₅), T₉ (Zn₅₊S₀), T₁₀ (Zn₅₊S₁₅), T₁₁ (Zn₅₊S₃₀), T₁₂ (Zn₅₊S₄₅), T₁₃ (Zn_7.5+S₀), T₁₄ (Zn_7.5+S₁₅), T₁₅ (Zn_7.5+S₃₀) and T₁₆ (Zn_7.5+S₄₅) for hybrid rice. The result showed that highest grain yield (62.95 and 65.50 q ha^-1) and straw yield ((90.25 and 93.85 q ha)) with 100% RDF + soil application of S@30kg and Zn@5 kg ha^-1 which was found higher to the magnitude of 44.87 and 53.58 per cent and of 20.41 and 27.95 per cent during both the years over the yield of their control. The result also indicated that maximum plant height (84.35 and 87.77 cm), number of tillers hill^-1 (10.49 and 11.15), number of hills m^-2(50.25 and 51.35), number of tillers m^-2 (502.50 and 564.80) and number of effective tillers m^-2 (467.50 and 529.80) recorded with soil application of 100% RDF + S@30kg and Zn@5 kg ha^-1 which was found higher during both the years over control. The results revealed that the treatments with soil combination of 100% RDF + S@30kg and Zn@5 kg ha^-1 significantly influenced the growth and yield of hybrid rice during both the years of experimentation.
