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 N 8 (25% RDN through Urea + 50 % through PM + 25% Gliricidia + Original Research Article
