This study examined the viability of prospective Jatropha based firms vis–a-vis employment opportunities in Nigeria, specifically the study identified the Jatropha bio-diesel and other allied products that were been researched into in Nigeria, estimated the costs and returns structure to Jatropha cultivation and the production of Jatropha based products. For the study, small scale Jatropha based firms were investigated. The results of the study revealed that Jatropha based products manufactured include bio-diesel, Jatropha kernel cake livestock feed, Jatropha ink pigment and dye, glycerine and Jatropha seeds-coat cement sheet and floor tiles. All the various parts of the Jatropha seeds are useful either for one or two of these products. Jatropha cultivation, was shown to be very profitable. Among Jatropha products, only the costs of the biodiesel Jatropha fuel is relative expensive when compared with the common fossil diesel. Based on the study findings, the study calls for the mobilisation of the Nigerian farmers to cultivate Jatropha, Alongside training to intimate the masses of the numerous products and benefits from Jatropha is necessary. They should be trained to manufacture simple Jatropha based necessities like those highlighted in the study. Market accessibility training to farmers and other stakeholders involved should also be embedded in the training. There is also the need to popularize the practicality of using Jatropha to produce these products via workshops and seminars. It is also necessary to step-up steps at introducing these products to the markets so as to enhance the marketability and competitiveness of the Jatropha based firms. Government and also other individuals and stake-holders need ensure the availability of supporting infrastructures for these small holder industries to thrive in the long-run.
