Abstract

Allelopathic effects of different doses of Eucalyptus camaldulensis leaf litters were investigated through an experiment in the green house of Institute of Forestry and Environmental Sciences, Chittagong, Bangladesh. Three popular agricultural crops: Falen (Vigna unguiculata), Chickpea (Cicer arietinum), Arhor (Cajanus cajan) and two widely used plantation trees: Sada koroi (Albizia procera) and Ipil ipil (Leucaena leucocephala) were selected as bioassay species. Experiment was set on tray at room temperature 27°C. The effects of different doses of leaf litter extracts were compared to the control. Results suggest that leaf litters of E. camaldulesis induced inhibitory effects. It was also found that the effect depend on concentration of extract and litterfall, type of receiver species. Higher concentration of the materials had the higher effect and vice versa. Though all the bioassay species were suppressed some of them showed better performance. Vigna unguiculata, Cicer arietinum are recommended in agroforestry based on this present Experiment output. In mixed plantation, Leucaena leucochephala is a better choice while compared to Albizia procera.
