A field experiment was conducted during 2014-15 and 2015-16 at Coimbatore in a clay loam soil, wetland to study the response of maize (Zea mays L.) to integrated nutrient management practices. Thirteen treatments were allotted to the randomized block design with three replications. Yield were higher for integrated nutrient management of resulting in higher grain yield in 100% RDF + vermicompost 5 t/ha (T1) 5358 kg/ha, Stalk yield 8350 kg/ha, Harvest Index 0.39 and net returns Rs.54888/ha, benefit cost ratio 2.78. This on par with 100% RDF + goat manure as pond silt 5 t/ha (T4) 5132 kg/ha, stalk yield 8050 kg/ha, harvest index 0.39. The net returns Rs.51272 ha, benefit cost ratio 2.66 for 2014-15 duration. The similar results followed resulting in higher gain yield in100% RDF + vermicompost 5 t/ha (T1) 5480 kg/ha, stalk yield 8542 kg/ha, harvest index 0.39, net returns Rs 56840, benefit cost ratio 2.84. This on par with 100% RDF + goat manure as pondsilt 5 t/ha 5280 kg/ha Stalk yield 8210 kg/ha, Harvest Index 0.39, net returns Rs 53000, benefit cost ratio 2.72 for the duration of 2015-16. This followed treatment comparable to the75% RDF+ vermicompost 5 t/ha. It was expressed better yield and economics in integrated nutrient management for maize in-rice-gingelly-maize cropping system through integrated farming system
