Effect of used Engine oil on the Growth and Development of Maize (Zea Mays).

ABSTRACT The disposal of used engine oil by vehicles of all descriptions - trucks, buses, cars, tri-cycles and motor- cycles into gutters is a common practice in Nigeria and in fact other countries in Africa - especially in the West African sub- region. This research work evaluated the effects of used engine oil on plant growth and development. A total of 25 poly pots were filled with 10kg of sandy - loam soil and mixed with four concentrations of spent engine oil 25, 50, 75, 100ml of which each treatment had 5 replicates. The result showed that the negative relationship existed between the oil level in the soil and growth parameters (plant height, number and size of leaves, root collar diameter, leave area and root length) measured were delayed. The reduction and effects on growth characteristics measured in maize with used engine oil increased as the contamination level increased compared to the control. Thus, the most reduction effects on all the parameters were reviewed in 100ml of used engine oil. This study therefore showed that the presence of engine oil had negative implication on the sustainability of maize (Zea mays) growth and development as well as vegetative plants and suggests that plant could be used as bio-indicators of pollution in oil spillage prone areas. Therefore, there is need for agencies and government to enact strict laws and educate the citizenry on the indiscriminate disposal of these pollutants (spent engine oil) on farms, gardens and environment. The risk effect to human health, poor agricultural yield that results and the damage to the soil impedes further its use for farm purposes. 'A stitch in time saves nine'. Motorists perpetuating this crime should be brought to book. This is the only sure way to increase food production particularly grains such as maize (Zea mays). With increased grain production, the burden of foreign exchange flight through grain importation will be reduced.
