The allelopathic activity can be determined by using both of Sandwich method and Dish pack method. These methods were used respectively for testing the effect of leaf litter leachate and leaf volatilization of selected weed species (act as the donor species) with three replications. The Sandwich method was carried out by using three different amounts of leaves which were 5 mg, 10 mg and 50 mg whilst the Dish pack method was done by using four different distances (41, 58, 82 and 92 mm) from the donor species. The pre-germinated Lactuca sativa (lettuce) was used as receptor plant. Among the 15 weed species, Crotalaria mucronata showed the highest inhibition on elongation for radicle of lettuce (81.34%) in Sandwich bioassay compared to the control, followed by Melastoma malabathricum (51.31%) and Asystasia gangetica (50.60%). Meanwhile, Mimosa pudica showed the highest inhibition on elongation for radicle of lettuce (27.00%) in Dish pack bioassay compared to the control, followed by Lantana camara (22.09%) and Acroceras munroanum (20.50%). The result obtained will provide the guideline information for elucidation of allelochemicals involved in this significant allelopathic interaction. 101 International Conference on Agriculture, Animal Sciences & Food Technology 2018 UNISZA
