Abstract:
A field experiment was carried out during the kharif season of 2016 and 2017 to study the observed the effect of integrated nutrient management on growth and yield of fodder maize (Zea mays L.) under foothill condition of Nagaland. The treatment consists of three factors each of them with three levels. The main plot factors consist three level of organic manures i.e., M₁ (10 t/ha FYM), M₂ (4 t/ha PM) and M₃ (2 t/ha VC); the subplot factor with three level of Recommended dose of fertilizer i.e., F₁ (0% RDF), F₂ (50% RDF) and F₃ (100% RDF); lastly the sub – subplot factors with three level of Zinc i.e., Z₁ (0 kg/ha), Z₂ (15 kg/ha) and Z₃ (30 kg/ha). Among different sources of organic manure M₂ i.e., poultry manure (4t/ha) was found to produce significantly better results in almost all the growth characters and grain yield of maize plant. RDF with higher levels i.e., 100% RDF dominated in producing significantly better results in growth characters and grain yield. Highest levels of Zinc i.e., 30 kg/ha recorded highest value in all the growth characters as well as grain yield. But it was found to be at par with 15 kg ha^-1 Zinc application in all the characters recorded except for dry matter.
