Abstract

This study was aimed at determining concentration of  allelopathy Ageratum conyzoides that suppresses growth of mustard. The research was conducted in Weeds Laboratory  and Screen House Agriculture Faculty, University of Syiah Kuala, Darussalam, Banda Aceh from December 2010 to February 2011. The experiment was arranged in a completely randomized design (CRD) with 6 treatments and 4 replicates.  Results showed that inhibition occurred at concentrations of 100 gL-1 at 10 HST on plant height, leaf number and dry weight of mustard plant. Optimum inhibitory concentration of the liquid squeezed leaves of A. conyzoides on mustard was at a concentration of 300 gL-1.   At the highest concentration (500 g/l), A. conyzoides inhibited germination up to 100%.
