The effect of spent engine oil on the root elongation and seedling evaluation of three species of pepper (Capsicum frutescens, Capsicum chinense and capsicum annum) was studied. There was increase in root elongation with 1% oil pollution concentration for C. frutescens and C. chinense while there was reduction in root elongation of C. annum due to delay in germination. Control of C. frutescens plant had mean root length of 4.667 ± 0.088 cm while 1% treated soil had 5.267 ± 0.145 cm. The control of C. chinense plant and 1% treated soil had mean root lengths of 4.467 ± 0.186 cm and 5.067 ± 0.120 cm respectively. C. annum control and 1% treatment plants had the mean root length of 4.365 ± 0.100 cm and 2.767 ± 0.145 cm respectively. The germination, growth and root elongation of the three pepper species were inhibited by the treatments of 3%, 6% and 9% concentration. There is significance difference (P <0.05) between the root elongations of treatment among C. frutescens, C. chinense and C. annum. Normal seedlings were observed for control plants of C. frutescens, C. chinense and C. annum but the 1% treatment plants had defect in the order of C. annum < C. chinense < C. frutescens.
