\begin{abstract}
\normalsize{
The responses of two crop plants (\textit{Vigna unguiculata} and \textit{Sorghum bicolor}) to crude oil pollution were compared in this study. This was done to determine the survival and the sensitivity of the crop plants to crude oil pollution. The seeds of the two crop plants were sown in soils experimentally contaminated with \mbox{1\,\%}, \mbox{2\,\%}, \mbox{3\,\%}, \mbox{4\,\%} and \mbox{5\,\%} crude oil (w/v). The control treatment had \mbox{0\,\%} crude oil and all treatments were replicated three times. The percentage germination, survival, plant growth, dry mater contents leaf area and chlorophyll contents were determined and the study lasted for 110 days. The percentage germination of \textit{V.~unguiculata} was significantly higher than that of \textit{S.~bicolor} in the \mbox{3\,\%} concentration ($p < 0.05$). \textit{V.~unguiculata} also had significantly higher percentage survival than \textit{S.~bicolor} ($p < 0.05$) in soils treated with \mbox{3\,\%} and \mbox{4\,\%} crude oil. The growth parameters were generally significantly reduced ($p < 0.05$) in the crops grown in soil contaminated with crude oil compared to the control treatment. The chlorophyll content of \textit{V.~unguiculata} was significantly higher than that of \textit{S.~bicolor} in all the treatments. The leaves of \textit{V.~unguiculata} started showing brown patches after seventy days exposure. The crop plants also responded differently to the various levels of contamination. After 110 days of growth more wilting was noticed in \textit{V.~unguiculata} than \textit{S.~bicolor}. This may imply that \textit{S.~bicolor} can survive for a longer time than \textit{V.~unguiculata} in crude oil polluted soil. Also, the results obtained may imply that \textit{V.~unguiculata} is a better candidate for biomoniotoring of crude oil pollution than \textit{S.~bicolor}.}
