There was no significant difference (p = 0.420) inthe plant heights on polluted soils compared to controlsoils. The plant height of each variety significantlydiffered (p<0.005) from one another, meanwhile therewas no significant difference in the plant heights amongthe replicates (p = 0.188). IT95K-1491 variety had thehighest plant height of 31.47 cm (Fig. 3) on gasolinepolluted soils. While variety Tvu164-67 recorded thelowest plant height of 22.5 cm on brewery effluentpolluted soils of all the polluted soils investigated inthis study (Fig. 3).
