Abstract: Coke production is one of the important
sources of pollution from steel industries. The effects of coke
(sludge of iron and steel) on seed germination and growth of Vigna
radiata (L.) R. Wilczek, Vigna mungo (L.) Hepper
and Vigna unguiculata (L.) Walp. were recorded. The seed
germination percentage of V. radiata was increased with increase
in coke concentration treatment at 25-50% as compared to control
treatment in petri dish. Seedling length and root growth performance
of V. radiata was also slightly increased with the increase
in coke concentration treatment at 75 and 100% as compared to
control. The seed germination percentage and root length of V.
mungo was reduced with increase in coke concentration treatment
at 25%. The obtained results showed more positive effects of coke
on seed germination and seedling growth performance of V. unguiculata
than V. mungo and V. radiata. Meanwhile, experiment
showed decrease in seedling vigor index of V. radiata
and V. mungo with the increase in concentration of coke
at 100% as compared to control. A gradual increase in seedling
vigor index for V. unguiculata with the increase in coke
concentration was observed. The coke extracts treatment influence
on the seedling tolerance indices of V. radiata, V.
mungo and V. unguiculata. The better tolerance to
coke treatment in all bean crops might be mainly due to some resistance
potential ability of seedlings to coke concentration.
