ARTICLE INFO ABSTRACT Article No.: 031120049 Type: Research In a field study, conducted at the Teaching and Research farm of Rivers State University, soil polluted with Bonny Light crude oil at 0% and 2% v/w was subjected to remediation processes using vetiver (Vetiveria zizanioides) and guinea grasses (Panicum maximum) amended with organic manures for a period of twelve months. Two weeks after pollution, poultry and Rabbit manures were applied at 0, 10, 20 and 30 tons/ha respectively. Vetiver and Guinea grasses were planted two weeks later. It was fitted in factorial split plot. Results showed 80% of vetiver survived in contaminated unamended plots against 85% in control, percentage survival in guinea grass was 60% in contaminated unamended against 85% in control. There was initial delay in germination on contaminated plots for the two grasses. Amendment of the soil with organic manure improves the growth and performance of the grasses. Vetiver height was significantly (p<0.05) different from guinea grass in contaminated unamended plots implying that vetiver has better adaptation to pollution than guinea grass. Remediation of soil with vetiver and guinea grasses degraded the THC in the soil to 23 and 21% respectively; amendment of soil with different levels of organic manure increased the level of degradation to 70.6 and 67.9% for vetiver and guinea grasses respectively. Vetiver uptake of THC in plant tissues was significantly (p<0.05) different from that of guinea grass. Amendment of the soil with organic manure reduced the uptake. Generally, both grasses were tolerant to THC with vetiver being more tolerant with higher survival rate. Poultry manure as amendment material planted with vetiver grass was more effective than rabbit manure in remediation of crude oil contaminated soil.
