Amaranthus Hybridus-phytoremediation

Phytoremediation is the direct use of living green plants for in situ, or in place, removal, degradation, or containment of contaminants in soils, sludges, sediments, surface water and groundwater. Phytoremediation is a low cost, solar energy driven cleanup technique. Fallouts from crude oil pollution of soils are known to have undesirable effects on plant growth. This research attempts to study the growth of Amaranthus hybridus grown on a crude oil polluted soil bioremediated with Pleurotus pulmonarius (a white rot fungus) and Glomus mosseae (a mycorrhizal fungus). Nine different treatment factors were used while three replicates were used for each treatment in randomized Complete Block Design at the same age of the seedlings. These treatment factors include: sterilized and unsterilized soil, crude oil, mycorrhiza, mycelium of the mushroom and its spent mushroom compost. Amaranthus hybridus was cultivated in the nursery for 3 weeks by broadcasting. The seedlings were later transplanted to experimental pots of 12cm depth, containing 1000g of soil. Seedlings were left to establish properly for a week before the soil in the experimental pots were polluted with crude oil (bonny light) in 0%, 2%, 3%, 4% concentrations. These were allowed to grow for six weeks before the experiment was terminated. Data from greenhouse experiment comprising of A. hybridus grown in pots replicated thrice in both sterilized and unsterilized soils were obtained from seedlings of 9-week old A. hybridus.
