The Growth Performance of Zea mays in Spent Engine oil Contaminated Soil Amended with Sawdust.

This was carried out at the University of Port Harcourt Green House to investigate the growth performance of Zea mays in spent engine oil contaminated soil amended with Sawdust. The contamination levels of 2%, 4%, 8% and 10% were used to contaminate 3kg of loamy soil and amended with 100 kg of Sawdust in various levels of spent engine oil, alongside a Control treatment of Sawdust and without Sawdust were replicated three times in Complete Randomized Design. The growth parameters (plant height, leaf area and number of leaves) and plant biomass (fresh weight, dry weight and moisture content) were examined and the data were subjected to Analysis Of Variance (ANOVA). Based on the results, the growth parameters and plant biomass examined decreased with increased levels of contaminations, however Control significantly (P=0.05) had greatest growth performance in all the growth parameters and plant biomass among all the treatments studied (Control + amendment, 2%,4%,8% and 10% spent engine oil amended soil) except fresh weight. Control + amendment significantly (P=0.05) performed better than all spent engine oil amended soil apart from 2% spent engine oil amended soil in plant height, leaf area, number of leaves, fresh weight and dry weight .This showed the potential of sawdust in improving the soil component and thus reduction in the level of toxicity of spent engine oil contaminated soil and thus suggests that compost of Sawdust is an effective organic supplement for remediation of spent engine oil contaminated soil where Zea mays is cultivated.
