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.
