Variations in nutritional potentials of some edible vegetables grown on crude oil post remediated agricultural soil was carried out after four
weeks of growth on the bioaugmented and natural attenuated soils. The result showed variations in both the vitamin content and proximate
composition of the vegetables. Telfairia occidentalis grown on bioaugmented site had the highest concentration of vitamins B2, B3 and E
with an increase of 16.5425 % for vitamin B2 and decrease of 7.8747 % and 6.6143 % for vitamins B3 and E, while Tallinium triangulare
grown on natural attenuated site had the highest concentration of vitamins A, B1, B2, B3, B6, C and E with decrease of 12.7558 %, 5.3239
%, 6.2900 %, 2.4000 %, 2.8834 %, 0.1508 %, and 21.4117 %. Moreover Amarantus hybridus grown on the natural attenuated site had the
highest increase in vitamins A, B1, B6, C and E with decrease of 5.4216 %, 16.2200 %, 4.7159 %, 1.7580 % and 3.5965 %. Proximate
composition of the vegetables showed that Telfairia occidentalis grown on bioaugmented site had the highest concentration of lipid,
carbohydrate, moisture, and crude fibre with increase of 125.1487 %, 3.0111 %, 3.0600 % and 6.2500 % respectively, while Tallinium
triangulare grown on bioaugmented site had the highest concentrations of lipid, carbohydrate and ash with increase of 430.0000 %,
27.7592 % and 31.2846 % respectively. However, Amarantus hybridus also grown on bioaugmented site had the highest concentrations of
lipid, carbohydrate and moisture with increase of 349.9631%, and 1.4593% for lipid and moisture, while carbohydrate had a decrease of
12.4762% when compared to their respective controls.
