The influence of site variation of Jatropha curcas on seed biodiesel yield and quality from three seed sources (Ibadan, New Bussa, Kano) was investigated. Seeds were collected from the three sources and oils from the seeds were extracted. Thereafter, biodiesels from the oils were produced using standard laboratory methods. The design of experiments was a completely randomized design at three replicates per treatment. The biodiesels produced were subjected to physico chemical analysis to elicit the quality of the biodiesel from the three seed sources.
The seed yield from Ibadan seed source was higher (227.10g) than New Bussa and Kano seed sources. Also, New Bussa (175.20g) has higher seed yield than Kano seed source (51.30g). However, the oil yield from Kano seed source was higher (59%) than New Bussa seed source (44.25%) while it was lowest (39.38%) for Ibadan, seed source. The biodiesel yield from Kano seed source (76.94%) was higher than New Bussa seed source (64.45%) and lowest for Ibadan (49.44%) seed source. With respect to quality, biodiesel from Kano seed source has the highest quality of biodiesel judging from the physicochemical properties of biodiesel produced from the seeds collected from the three seed sources. Jatropha curcas grown in forest and savanna ecological zone of Nigeria has a potential for high oil yield and high quality of biodiesel production.
