Abstract
The allelopathic substances are organic agents which are produced and released by a
plant that cause alteration on the neighboring plants. The characteristics of allelopathic substances usually inhibit germination of other species and sometimes will reduce the plant growth. This research was aimed to determine the effect of Puararia javanica leaf extract and also to determine optimum concentration on seed germination and growth of weeds Borreria alata in field condition. This experiment used to extract concentration
0, 2, 6, 18 and 54%. The experiment showed that germination and growth of Borreria
alata were reduced by leaf extract of Puararia javanica. The highest germination and growth inhibition at concentrations of the leaf extract 54% respectively are 50% and
60.27%
