The presence of weeds in the crop can become a competitor and reduce crop production. Each type of weed and naturally materials contains different allelochemical compounds. This research aims to create appropriate technology for weed management in maize cultivation, especially in the early growth phase (germination) so that it can suppress the effect of weeds at the beginning of growth and increase maize growth. The research used a completely randomized design (CRD) with 8 treatments namely aquadest (without weed extract/control), extract of the weed in the teki groups (Cyperus rotundus), grass weeds (Dactyloctenium aegyptium) and wide leaf weeds (Euphorbia heterophylla), ketapang, beluntas, acacia, and ginger (Zingiberaceae). The results showed that weed extract of D. aegyptium gave the greatest effect of inhibition of germination compared to C. rotundus and E. heterophylla at 12 DAS. Ginger leaf extract (Zingiberaceae) had the greatest effect on inhibition of germination compared to ketapang, beluntas, and acacia on corn seeds at 7 DAS. The application of weed extracts and natural ingredients can have an inhibitory effect, especially on the growth phase, namely the maize germination phase.
