Field experiment was conducted to find out the influence of intercropping and fertilizer levels on the productivity and economics of maize based food cum fodder intercropping system at Tamil Nadu Agricultural University, Coimbatore during kharif2017.The experiment was laid out in split plot design and replicated thrice. The experiment consisted of four intercropping systems viz., Sole grain maize, grain maize + fodder maize (1:1), grain maize + fodder maize + fodder cowpea (1:1) in alternate rows, grain maize + fodder maize + fodder moth bean (1:1) in alternate rows under main plot and three fertilizer levels, 100% RDF, 125% RDF and 150% RDF under sub-plot. The results of the experiment revealed that the grain yield of maize was higher under sole maize followed by maize + fodder maize + fodder cowpea and was comparable. Among the fertilizer levels, 150% RDF recorded higher yield followed by 125% RDF and both were comparable. Among the treatment combinations, higher land equivalent ratio and grain equivalent yield were recorded under the treatment combination of maize + fodder maize + fodder cowpea along with 150% RDF. However, the net return and BC ratio were higher under maize + fodder maize + fodder cowpea with 125 % RDF.
