Abstract: Organic extract derived from the leaves of the edible plant, Syzygium malaccense was used to determine their allelopathic potential in relation to the seed germination of the crop plants; black mustard (Brassica nigra), chickpea (Cicer arietinum), mung bean (Vigna radiata), and big gram (Vigna unguiculata). The seeds of Brassica nigra and Cicer arietinum showed the highest susceptibility towards the extract. The methanolic extract of S.malacansis induced 100% inhibition on the germination of Brassica nigra and Cicer arietinum. Vigna unguiculata and Vigna radiatawere showed 80.23%and 86.33% inhibition respectively. The germination study was conducted using the petri dish method and the percentage of Inhibition of Germination (I) was calculated using specified equation. This results revealed the strong allelopathic potential of Syzygium malaccense which necessitates further studies to testits allelopathiceffect under field condition and to identify the toxic principle, their quantification and efficacy in the soil.
