Abstract: A field experiment was conducted at field no. 6 Student’s Instructural 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).
