The field experiment was carried out at MARS, Dharwad during kharif 2010–11 and 2011–12 to study the impact of organic farming practices on yield and economics of organic production system. The results of two years’ pooled data revealed that combined application of compost (50%)+vermicompost (50%) equivalent to RDF+green leaf manure as mulch with application of jeevamrutha @ 500 l/ha recorded higher kapas yield (1640 kg) and it was superior over RDF alone (1522 kg/ha). Combined application of crop residue (50%)+vermicompost (50%) equivalent to RDN with lucerne with jeevamrutha @ 500 l/ha surface application recorded significantly higher net returns (Rs. 60009/ha) over other combinations.
