Online published on 24 December, 2014. Abstract Field experiments were conducted at Thalingipalayam block (Avinashi, Tiruppur district of Tamil Nadu) India during 2011–2012 to study the effect of organic manure (seriwaste compost + goat manure + poultry manure + farm waste) obtained from Integrated Farming Systemon maize-sunflower sequential cropping system for enhancing productivity and economics. The experiments were laid out in randomized block design with three replications. The organic manures of various regimes (25%, 50%, 75% and 100%)were applied along with Nitrogen (N), Phosphorus (P), Potassium (K) levels (150:75:75 kg ha {1) at different levels (25%, 50%, 75% and 100%). The results revealed that plant growth, Dry matter production, yield, soil fertility and economics were found to be higher with integrated nutrient supply through 100% of RDF+75% of organic manure from Integrated Farming System components with increased net returns and B:C ratio which was on par with 50% RDF +50% organic manure in maize-sunflower sequential cropping system.
