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 test variety PHB-71 of hybrid rice was raised with different treatment combinations of sulfur and zinc. The highest cost of cultivation (55316 rupees ha^-1) was recorded with application of S@45 kg ha^-1 and Zn @7.5 kg ha^-1 while it was noted minimum (47536 rupees ha^-1) under control (T₁) during both the years. Maximum gross return (141329 and 150509 rupees ha^-1) was recorded with the application of application of 100% RDF + S@30kg and Zn@5 kg ha^-1 followed by 100% RDF + S@30 kg ha^-1 and Zn@7.5 kg ha^-1 during both years. The net realization (87075 and 96255 rupees ha^-1) and BCR (2.60 and 2.69) was found maximum with the application of 100% RDF + S@30kg and Zn@5 kg ha^-1 during both the years of experimentation.
