A field experiment was conducted at the instructional farm, Department of Agricultural Chemistry and Soil Science, SASRD, Nagaland University, during the Kharif season of 2019 to study the productivity of maize (Zea mays L.) as influenced by nutrient omission in Inceptisols of Nagaland. The experiment was laid out in randomized block design with three replications and seven treatments. The growth, yield attributes and yield of maize were found to be superior in the treatment where all nutrients (N, P, K, Zn, B, lime) were applied. Maximum grain and stover yield (3975.03 and 5107.66 kg ha-1, respectively) were recorded with treatment T1whereas the lowest was observed with omission of N (2996.91 and 3940.51 kg ha-1, respectively).N, P, K, Zn, B and lime omission reduced grain yield to the extent of 24.6, 21.0, 13.6, 8.0, 9.1 and 17.4 % respectively over T1 treatment. The per cent grain yield reduction based on limiting nutrients were found in the order N>P > Lime >K>B > Zn. The nutrient uptake by maize, available nitrogen, phosphorus, potassium, exchangeable calcium and magnesium, available zinc and boron in post-harvest soil were found significantly higher under the treatment T1.
