An experiment was conducted during rabi season 2016-17 on crop research farm of department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, SHUATS, Allahabad. It may be concluded from trial that the different levels of NPK, Zinc and Neem cake in the experiment gave highest value. The maximum bulk density (g cm-3) was recorded in the treatment combination of T2[NPK@0%, Zinc@50% NSC@0%], the maximum particle density (g cm-3) was recorded in the treatment combination of T11 [NPK@100% Zinc@50% NSC@50%], pore space (%) in the treatment combination of T11[NPK@100%, Zinc@50%, NSC@50%], solid space (%) in the treatment combination of T9[NPK@100%, ZINC@0%, NSC@50%] and water retaining capacity (%) was recorded in treatment combination of T11[NPK@100%, Zinc@50%, NSC@ 50%], was found to be the best for improvement of physical properties of soil with the level of NPK, Zinc and Neem cake in the experiment gave highest yield. The maximum pH was recorded in T8[NPK@100%, Zinc@0%, NSC@0%]. Maximum EC (dSm-1) was recorded in the treatment combination of T9[NPK@100%, Zinc@0%, NSC@50%] and organic carbon (%) was also recorded. The available nitrogen (kg ha-1), phosphorus (kg ha-1), potassium (kg ha-1) and zinc (ppm) with the treatment combination of T11[NPK@100%, Zinc@50%, NSC@50%], respectively was found to be the best for the improvement soil chemical properties due to integrated nutrient management. Therefore, farmer of Allahabad region can adopt this combination to give the highest yield of Maize.
