Integrated farming system (IFS), comprising the components like cropping, vegetables, fishery, poultry and goat rearing was undertaken at Agricultural Research Station,  Siruguppa, Karnataka, India during the wet and dry seasons of 2003-04 and 2005-06 to study the productivity, profitability,  energy  flow,  employment generation and water requirement of IFS over conventional rice-rice system in Tungabhadra project area of Karnataka.  Integrated farming system approach recorded 26.3  and 32.3 per cent higher productivity and profitability, respectively over conventional rice-rice system.  Among the components evaluated,  the highest net returns was obtained from crop (63.8 %), followed by goat (30.9 %), fish (4.0 %) and poultry (1.3 %),  respectively.  Employment generation  and water requirement was 275 Man days/ha/year and  1247 mm, respectively under the integrated farming system. Specific energy was low in IFS (3.09 MJ/kg).
