Eucalyptus globulus L.(Myrtaceae) stared as antisocial tree for social forestry (Kohli, 1987) is commonly transplanted through out India on roadsides, bare lands and boundaries of crop fields without considering its allelopathic effects on crop plants, especially cereals and pulses. The aerial parts, especially leaves of this tree contain volatile tarpenes (Del Moral and Muller, 1970), water soluble toxins and growth inhibitors. (Grummer and Beyer, 1960 and Al-Mousawi, Al-Naib,1976 and Pandhy et al. 1992). Toxic effects of different concentrations of leaf extract of Eucalyptus globulus (Viz-5,10, 15, 20 & 25 percent) was studied on percentage of seed germination,their survival, growth of radical and plumule and establishment of secondary roots on three species of Vicia-V. narborensis, Vicia benghalensis. and V. faba.In the present investigation each concentration showed inhibitory effects of the above parameters which gradually increases with increasing concentra- tions of the leaf extract. Delayed germination was also noticed in the treated seeds. Vicia narborensis proved to be more sensitive to these toxic leachates than the other two species. The above findings clearly showed that the transplantation of Eucalyptus species on boundaries of crop plants should be totally banned. Further investigation on its Cytotoxic effect (if any) is in progress.
