【 摘 要 】

Ever since it was demonstrated that Jatropha seed oil could be converted into a world class biodiesel and could run in unmodified stationary and mobile diesel engines with simultaneous reduction in emissions, it caught the attention of the world. The capability to grow this crop on wastelands added to its attractiveness. However, the single biggest challenge came in the form of the availability of adequate feed stock in the form of the Jatropha fruit. Adequacy of feed stock can only be possible if large plantations are cultivated and produce enough fruit. The people, world over, jumped into Jatropha cultivation without heeding to the need to first ensure quality germplasm and understand the agronomic requirements of the plants. As a result many plantations failed to give the required yield. CSIR-CSMCRI had been researching Jatropha and had an end-to-end approach, i.e., it developed the best technology to prepare biodiesel and also worked towards the practical problems that it envisaged to be important for raising Jatropha productivity. It focused only on cultivation on wastelands as this was the only practical strategy, given the limited arable land India has and the risk of food security for the burgeoning population. While working in this direction, the Institute zeroed-in on a few germplasm, which gave consistently higher seed yield over several years. These germplasm were clonally propagated in large numbers to be raised in experimental plantations at different geographical locations in India. Many agronomic practices were developed as a part of these different projects. It was at this juncture that General Motors and the U.S. Department of Energy joined hands with CSIR-CSMCRI to further the work on Jatropha. A center of expertise for Jatropha was established and work was initiated to further refine the understanding regarding the best practices. Efforts were to be made to generate primary data, hitherto unavailable for wastelands, on which life cycle assessment studies were to be performed as a part of the project.
