Allelopathic effects of different concentration of water extracts of Eupatorium odoratum leaf on germination and growth behavior were tested by using some agricultural crops e.g. Cicer arietinum; Brassica juncea; Cucumis sativus; Phaseolus mungo; Raphanus sativus and Vigna unguiculata as bioassay material. The experiment was conducted in sterilized petridishes with a photoperiod of 24 h on average temperature of 28.50C. The effect of the different concentration of aqueous extracts was compared to distil water (control). The result revealed that different concentrations of Eupatorium odoratum leaf extracts caused significant inhibitory effect on germination, root and shoot elongation and development of lateral roots of receptor crops. Bioassays indicated that the inhibitory effect was proportional to the concentrations of the extracts and higher concentration had the stronger inhibitory effect whereas in some cases the lower concentration showed stimulatory effect. The study also revealed that inhibitory effect was much pronounced in root and lateral root development rather than shoot and germination.
