description Allelopathy is the compound released by the plants (example: blady grass) to the environtment and where another plants is living and could obstruct or extinguish to another plants.  The purpose of research were to figure out the effect of allelopathy  from the blady grass toward the species of acacia seedlings, to figure out the weakest affected seedling species by blady grass allelopathy, and to figure out interaction between concentration of  extracted blady grass and seedling tree species.  The research was designed based on factorial in a complete random design.  Factor I was the seedlings, consisted of acacia, mangium, and acacia alba, while factor II was concentration of extracted blady grass allelopathy, consisted of non extracted allelopathy, extracted allelopathy 25%, extracted allelopathy 50%, extracted allelopathy 75%, and extracted allelopathy 100%. Every treatment was repeated 5 times. The number of the seedlings for each experimental unit was two seeding. The observed variables  were height, diameter of the stem, number of leaves, and living percentage of the seedlings.  This observation data was tested by Bartlett test to find the variance homogenity.  Then it was analyzed by using variance analysis, and tested by least significant difference (LSD).  The calculation were done at 5% significant level.  The result of this research showed that allelopathy of blady grass were significan to the growth of acacia, mangium and acacia alba seedlings. Based on the LSD at 5% was known that the concentrate of blady grass allelopathy had strongest negative effect to the growth seedlings was 100%.  Seedling that was the most resistant to the allelopathy of blady grass is mangium seedling.  It was known from the analysis of variance test there was an interaction between the seedling and the concentration of blady grass allelopathy that effect the height, leaves number, living percentage ofseedlings.   Key words : allelopathy, blady grass, and acacia
