| Abstract |
A study was conducted in 2010 at the Research farm of the Department of Forestry and Wildlife, Faculty of Agriculture, Delta State University, Asaba Campus, Nigeria to assess the germination response of Jatropha carcas seeds as influenced by crude oil in soil using crude oil levels of 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0 0/0 w/w . The seeds were planted in the soil – crude oil- mixture in bottom perforated polypots. The experiment was arranged in a randomized complete block design and replicated four times. The results showed that contamination of soil with crude oil significantly (P≥ 0.0 5) reduced the percentage germination, increased days to germination and reduced rate of germination of the test plant relative to the seeds planted in the uncontaminated soils and the effects of the germination parameters were generally oil concentration dependent. No germination was observed in J. carcas seeds sown in 10.0 0/0 of the crude oil. This study has demonstrated that soil contamination with crude oil has significant effects of reducing the germination spouse of J. carcas.
