Abstract: This laboratory study measured the growth of tomatoes (Solanum lycopersicum) in soils artificially contaminated with Bonny light crude oil at 5, 7.5 and 10% level (w/w). Tomatoes grown in nursery trays were supplemented with compost at a mix ratio of compost/soil 1:1 which is equivalent to 50% compost (w/w). The results showed that germination of seeds without the addition of compost was adversely affected by the oil pollution. In the controls (without oil), the highest biomass yield of 492 mg was recorded at 50% compost/soil and the lowest yield of 245 mg in soil only (without compost). However, there was total inhibition to growth at initial 10% oil level suggesting that 10% oil level is above the trigger level for plant growth. On addition of compost, contamination levels were diluted and plants grew in soil with the least diluted content of 5% oil level. The aboveground biomass yield was enhanced reaching 130±22, 55±9.8 and 39±36 mg at 2.5, 3.75 and 5% diluted oil concentrations, respectively.
