Abstract:
A field experiment conducted during summer seasons of 2021-22 at Agricultural Research Farm of Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj (UP). Effect of Different levels of NPK and Zn on Physico-Chemical Properties of soil, Growth and yield Attributes of Maize (Zea Mays L.) Keeping in this view experiment was conducted in RBD with three replications Treatments are T₁-0% NPK + 0% Zn, T₂-0% NPK + 50% Zn, T₃-0% NPK + 100% Zn, T₄-50% NPK + 0% Zn, T₅-50% NPK + 50% Zn, T₆-50% NPK + 100% Zn, T₇-100% NPK + 0% Zn, T₈-100% NPK + 50% Zn, T₉-100% NPK + 100% Zn Results showed that T₁ is superior in soil bulk density and pH with 1.302 Mg m^-3, and 7.73 respectively and T₉ is superior in particle density, pore space, water holding capacity Electric Conductivity, organic carbon available nitrogen, phosphorus and potassium with 2.483 Mg m^-3, 51.02%, 46.01%, 0.25dS m^-1, 0.248%, 271.15 kg ha^-1, 19.24 kg ha^-1 and 148.45 kg ha^-1 respectively and T₉ is inferior in bulk density, and pH with 1.253 Mg m^-3, and 7.73, respectively and T₁ is inferior in soil particle density, pore space, water holding capacity, Electric Conductivity, organic carbon and available nitrogen, phosphorus and potassium with 2.314 Mg m^-3, 44.82%, 37.90%, 0.16 dS m^-1, 0.231%, 251.12 kg ha^-1, 16.12 kg ha^-1, and 117.65 kg ha^-1, respectively.
