Effect of Integrated Nutrient Management on Growth and Yield Attributes of Maize (Zea mays L.) Intercropping System with Green Gram under Island Ecosystem, A&N Islands

Abstract

An experiment was conducted during Rabi season of dry months (January to April) of 2016 and 2017 at Field crops Experimental Research Farm Bloomsdale, Chouldhari, ICAR- CIARI, Port Blair, Andaman and Nicobar Islands to study the Effect of Integrated Nutrient Management on growth and yield attributes of Maize (Zea mays L.) Intercropping System with green gram under Island Ecosystem. The experiment was laid out in randomized block design (RBD) with three replications each consisting of two intercropping 1:1 and 2:2 ratios and eight nutrient sources. The main plots treatments include maize, green gram inter cropping ratio, with 8 nutrient applications. The results indicated that the intercropping of (Maize + Green gram (2:2) + 25% RDN through Urea + 75% N through Poultry Manure + 25% Gliricidia+ Azotobactor) series was found to be the most effective under experimental conditions, gave best result in term of growth yield and character which is statistically at par with N8(25% RDN through Urea + 50 % through PM + 25% Gliricidia + Azot), N7(25% RDN through Urea + 50% N through VC + 25% Gliricidia + Azot.) and N6(25% RDN through Urea +50% N through FYM + 25% Gliricidia + Azot.), gave the maximum net returns and maximum benefit: cost ratio.
