JATROPHA: A Goldmine Plant

Jatropha is a hearty multipurpose shrub type tree that grows wildly in Nigeria with little or no maintenance. The oil-rich seeds are very attractive feed stock for biofuel production. The kernel consists of about 60% oil which can be transformed through esterification into biofuel. The green energy of the plant can be used to power various machines while the biofuel mix was reported as being more efficient and burn less fuel in total than the conventional one. It burn with clear smoke-free flame.
Additionally, the plant is cherished for its medicinal value and the cake can be used as livestock feed if properly processed. It is noteworthy that, the distribution, establishment, management, harvesting and uses are not documented in Nigeria. The fact that the biofuel can be used to replace fossil fuel or substitute fuel wood is enough to encourage its cultivation in Nigeria hence, this paper discussed on the values of Jatropha plant in Nigeria.

It can tolerate low temperature and light frost. The plant requires less water and can withstand drought condition. It needs a mean rainfall of between 300 and 1000mm and a mean temperature of 20-28oC .
