Umudike to investigate the germination ability of eleven accessions of African yam bean seeds in spent engine oil (SEO). The experiment was laid out in Complete Randomized Design (CRD). Seeds of the eleven accession of African yam bean were presoaked in water for 24hours and thereafter soaked in spent engine oil for varying hours 0, 1, 2, 4, 8 and 16 hours. The seeds were placed in Petri dish lined with moist tissue paper. The result obtained showed that the germination percentage, days to

... nation and rate of germination of the AYB accessions were time and accession dependent. The germination ability of seeds decreased as number of hours soaked in spent engine oil increased. AYB-11, AYB-04, AYB-03 and AYB-07 were more tolerant to oil among the African yam bean accessions studied hence could be considered to be used to boost food security in oil producing areas of the Niger Delta.
