A study was undertaken under rainfed conditions to develop pond-based IFS models for smallholder farm of 1.6 ha comprising rice-onion cropping system, multilayer pisciculture, poultry and mushroom with conventional rice-green gram cropping system. Field experiments were conducted at five cluster of villages located in five different blocks viz. Khajuripada of Kandhamal district, Dhenkanal Sadar and Odapada of Dhenkanal district, Golamunda and Narla of Kalahandi district of Odisha under rainfed medium land situations during 2010-11 to 2012-13. The IFS model gave rice equivalent yield (REY) of 28081 kg/ha, net return of 1,42,201/ha and B : C of 1.82 as compared to REY of 4188 kg/ha, net return of 9522/ha and B:C of 1.25 in conventional rice-greengram cropping system. Among the clusters, Narla cluster recorded the maximum REY of 17,119 kg/ha closely followed by Dhenkanal Sadar with REY of 17,038 kg/ha. The 1.6 ha IFS model provided 5461 kg grain of rice, 29,811 kg of onion, 443.6 kg fish, 1983.0 kg raw fruit yield of papaya, 1083.0 kg fruit yield of plantain, 642.0 kg drumstick, 847.0 kg poultry meat, 901.2 kg paddy straw mushroom and 714.4 kg oyster mushroom to the farm family and recyclable by-products of 5940 kg paddy straw, 5000 kg pond silt, 2104.0 kg poultry excreta and 13022 kg mushroom spent for recycling in the system and use as inputs by other enterprises in the models. The 1.6 ha rainfed farm with conventional cropping provided 4290 kg grain of rice and 750 kg of green gram for consumption by the farm family. The Sustainable Yield Index (SYI) and Sustainable Value Index (SVI) values were 0.82 and 0.44, respectively, in pond based IFS model as compared to 0.13 and 0.03 in conventional cropping system of rice-green gram sequence cropping under rainfed conditions.
