There was no significant difference in shoot dry mass
among varieties (p = 0.209) and replicates (p = 0.929).
Tvu164-67 recorded the highest mean dry mass of
7.153 g on piggery soils (Fig. 5) while IT845-249
variety recorded the lowest mean dry mass of 1.267 g
on gasoline polluted soils of all the polluted soils used
in this study (Fig. 5).
