Abstract
A field experiment was conducted at the research farm, SASRD, Nagaland University, Medziphema during the Kharif season of 2019 to study the productivity of maize (Zea mays L.) as influenced by nutrient omission in Dystrudept of Nagaland. The experiment was laid out in randomized block design (RBD) with three replications and seven treatments. Results revealed that growth, yield attributes and yield of maize were found significantly superior under the treatment where all the nutrients (N, P, K, Zn, B, lime) were applied. It was observed that the most limiting nutrient for the growth and yield of maize was nitrogen followed by phosphorus and lime. Omission of N, P, K, Zn, B and lime reduced grain yield to the extent of 24.6, 21.0, 13.6, 8.0, 9.1 and 17.4%, respectively over all the treatment. The nutrient uptake by maize was found significantly higher in the treatment with all nutrients. Omission of various nutrients significantly reduced the nutrient uptake by maize. Omission of N, P, K, Zn and B reduced their respective uptake by 55.5, 63.1, 43.7, 24.0 and 25.8%, respectively over all the nutrients treatment. Lime omission declined Ca and Mg uptake by 47.2 and 44.5%, respectively. The available major and micro nutrients in post-harvest soil were found significantly higher under the treatment which contains all the nutrients. Omission of N, P, K, Zn and B significantly reduced their respective available content in post harvest soil and lime omission significantly reduced ex. Ca and Mg content of experimental soil. Soil pH was significantly lower and total potential acidity was significantly higher in lime omitted plots.
