The bioherbicidal efficacy of aqueous extracts of N. oleander on germination percentage, seedling growth, weed biomass and biochemical parameter of Bermuda grass (Cynodon dactylon L.) were tested. As per result, it was observed that aqueous extracts of N. oleander had a significant retardation effect on bermuda grass. At 20(g/l) concentrations, inhibitory effect was maximum than other lower extracts. Seedling length, fresh and dry weights was also reduced significantly over control. The phytotoxic effect was directly proportional to the intensity of aqueous extract concentration. At 20(g/l) extract concentration, inhibition on bermuda grass was highly notable (upto 79%) which is quite prove to use N. oleander as a bioherbicidal agent to control bermuda grass in paddy fields.
