Integrated farming is a sustainable and effective tool for improving rural economy due to its cumulative cost effectiveness, low investment and higher profitability. It optimises the farm productivity per unit area through incorporation of recycling wastes and residues from one farming system to the other with due environmental consideration. Considering the efficacy of this viable production system, the study was conducted by the Dakshin Dinajpur Krishi vigyan Kendra, Uttar Banga Krishi Viswavidyalaya, W.B. in purposively selected Dakshin Dinajpur district of West Bengal as On Farm Trial (OFT). The trial was conducted in 03 different treatment options and in each option minimum seven (07) replications were taken under farm field condition. The system components fishery and animal Husbandry (Duckery) are complementary in which duck droppings act as nutrient source for Fish culture. Vegetable growing in the trellis and dykes is an additional component which helps in maximising profit from unit area. The data were collected from each treatment for consecutively 03 years to judge the economic profitability and sustainability of the practice. The generated data were computed and analysed through statistical tools and overall economic return in terms of productivity of the fishery, duckery and vegetable cultivation practices, their gross return, net return and ultimate B:C ratio. It was observed that better production and sustainable economic return can be achieved through crossbred duckery and fish culture along with dyke vegetable cultivation in pond based integrated farming practices
