Abstract:
A field experiment was conducted at field no. 6 Student’s In structural Farm at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the Kharif season 2017 to find out integrated nutrient management effect on maize with ten treatments i.e. T₁ (125% RDN), T₂ (100% RDN), T₃ (100% RDN + 25% N FYM), T₄ (100% RDN + 25% N FYM + S₃₀)_, T₅ (100% RDN + 25% N FYM + S₃₀ + Zn₅)_, T₆ (75% RDN), T₇ (75% RDN + 25% N FYM), T₈ (75% RDN + 25% N FYM + S₃₀)_,T₉ (75% RDN + FYM + S₃₀ + Zn₅)_,T₁₀ (Control) in RBD with 3 replications. Maize variety Azad Uttam was taken for study. The results revealed that the N, P, K, S and Zn content in maize grain varies from 1.12 to 1.44%, 0.26-0.37%, 0.32-0.44%, 0.28-0.39% and 22.20-31.80% mg/kg and the N, P, K, S and Zn content of maize stalk varies from 0.34 to 0.55%, 0.110 to 0.142, 1.02 to 1.19%, 0.20 to 0.33% and 14.20-22.80 mg/kg respectively. The total uptake values of N, P, K, S and Zn varied from 43.27 to 107.58 kg/ha, 11.47 to 26.95 kg/ha, 67.19 to 132.11 kg/ha, 17.24 to 46.07 kg/ha and 1268.24 to 3355.10 g/ha. The maximum nutrient concentration and uptakes in case of all treatments was found in T₅ (100% RDN + 25% N FYM + S₃₀ + Zn₅) and lowest in T₁₀ (Control).
