| 1 | Uptake and Distribution of Total Petroleum Hydrocarbon by Sunflower from Crude Oil Contaminated Soils Using Agro-Industrial Wastes as Soil Amendments. |
This study investigated the growth performance of sunflower (Helianthus annuus L.) under different concentrations of petroleum hydrocarbon contaminated soils. This was with a view to assessing the remediating potentials of the test crop when different rates of agro-industrial wastes were used as soil amendments. The experiment was conducted in the greenhouse of the Faculty of Agriculture, Obafemi Awolowo University, Ile- Ife. It was a 5 x 3 x 3 factorial complete randomized design, consisting of 135 polythene pots, each containing five kg of sandy topsoil. Poultry waste and ashed sawdust in different ratios [0:100; 25:75; 50:50; 75:25 and 100:0] gave five manure mixtures which were applied at three levels (0, 4 and 8 t ha-1) as soil amendments. These manures significantly (p < 0.05) increased the uptake and accumulation of total petroleum hydrocarbon in the root (0.19-0.46 mg kg-1), shoot (0.75-1.71 mg kg-1) and grains (0.13-0.26 mg kg-1) of sunflower; however, with superior influence from 8 t ha-1 containing higher poultry waste and at 1 % crude oil soil contamination. The study concluded that sunflower has potential for the cleaning-up of petroleum hydrocarbon from crude oil contaminated soil, particularly when high composted poultry waste proportion in the manure mixtures was used as soil enhancer in the humid tropical climate. | 5.
