The research project was formulated to address the impact of World Trade Organisation (WTO) on domestic oilseeds production. The specific objective was to analyze the temporal growth in area, production and productivity of major oilseed crops  in India. The formulated hypothesis was growth rate of area, production and productivity of major oilseed crops in the post-WTO period is less compared to pre-WTO era. The results of the study have shown that area under rapeseed and mustard, soyabean, sunflower and castor increased with an overall annual compound growth rate of  2.13, 17.61, 9.15 and 1.85 per cent respectively. The increase in productivity of all nine selected oilseed crops put together from pre-WTO period to post-WTO period, was 140 kg per ha. The overall growth of productivity was positive in all the oilseed crops except sunflower. The mean production of the nine oilseeds put together had increased from 9.99 million tonnes during Pre- Technology Mission on Oilseeds (TMO) period to 17.68 million tonnes in pre-WTO period and to 22.33 million tonnes in post-WTO period.  To attain self sufficiency in edible oils and to achieve nutritional security, State and Central government should map out programmes on the line of TMO to increase and maintain sustainable growth in productivity of all oilseed crops in rainfed areas.
