ABSTRACT
A study was carried out during the 2003 and 2004 cropping seasons to investigate the effects of crude oil contaminated soil on the yield of seven maize varieties (Composite suwan 1, Hybrid 3x-yx, AMATZBR w, TZBRSYN w, AMATZBR y, TZBRSYN y and Ozoro local) in two locations (Asaba and Ozoro) in Delta State, Nigeria. Five crude oil concentrations (0.0, 5.2, 10.4, 20.8, and 41.6 mL per maize stand) applied to soil at seven weeks after planting (7 WAP) constituted treatments. The experiment was laid out in a split-split-plot arrangement and replicated four times. Locations of study were allotted the main plots, the crude oil levels, the sub-plots and the maize varieties, the sub-sub-plots. The results indicated that both the fresh grain yields and dry grain yields of the maize across locations and within locations were not significantly affected (p = 0.05) by crude oil application to soil up to 5.2 mL but higher levels of the oil contamination significantly (p = 0.05) reduced these characters. The Hybrid (3x-yx) variety had the highest fresh and dry grain yields across and within locations hence it should be recommended for planting in Asaba and Ozoro locations of Delta State. Ozoro local had the lowest grain yields among the varieties tested. This study has shown that crude oil contaminated soil has a highly significant effect of reducing the yields of maize. The present study also established varietal differences in maize with response to crude oil thereby providing a basis for future study by plant breeders.
