The present study was conducted with objectives to assess the growth and instability in supply and demand andto project demand and supply for oilseeds in Karnataka. The time series data on production of oilseeds in Karnataka,population and per capita income for 18 years were collected from the Directorate of Economics and Statistics, Bangalore.The National Sample Survey Organisation of India (NSSO) statistical data on consumer expenditure was also used. Therewas a declining growth in supply of total oilseeds (-2.58 %) with high instability (19.40 %) during the study period. Thedemand for total oilseeds increased at a rate of 4.94 per cent with low instability (0.94%) in Karnataka. The projectedsupply and demand for edible oilseeds would be 8.11 lakh tonnes and 24.01 lakh tonnes respectively by 2020 with asupply-demand gap of 15.89 lakh tonnes. Thus, the supply of oilseeds would be far below the requirement
