Trials were conducted between September and December in the year 2009 to determine the relationship between some soil properties and heavy metal uptake by Telfairia occidentalis using correlation coefficient (r) analysis. In the greenhouse, soil sample collected from surface 0-15 depth of soil was bulked mixed thoroughly, air dried, sieved and thereafter 5 kg weighed and put in each of the 96 pots. Each of the heavy metals (chromium nitrate Cr (N03)2 .9H20 and lead nitrate Pb (N03)2) was applied at 0, 50, 100, 200 mg per 5 kg soil. While in the field, the heavy metal rates of 0, 20, 40, 80 kgha-1 equivalents to 0, 50,100,200 mg per 5 kg soil were used in a treatment combination of 2 x 4 factorial organized in Randomized Complete Block Design in three replicates and each replicate had 32 pots. Results revealed that the soil pH, amorphous Al oxide, amorphous Fe oxide, free Al oxide, free Fe oxide, available Phosphorus (P), effective cation exchange capacity, organic carbon (C), sand, silt and clay negatively correlated with lead (Pb) and chromium (Cr) uptake by the plant and were significant at (P<0.05) level of probability. Also, revealed that increase in these soil properties decrease the uptake of these metals. Therefore, it is advisable to maintain these soil properties at higher levels to reduce the heavy metal uptake by Telfairia occidentalis
