Allelopathy Effect of Ageratum conyzoides Leaves and Imperata cylindrica Roots on Seed Germination and Plant Growth of Mung Beans

Abstract

Ageratum conyzoides, and Imperata cylindrica  are cosmopolite weeds in agricultural land that can reduce the productivity of cultivated plants. This study aims to analyze the effect of A. conyzoides  leaves biomass and I. cylindrical former plant media on the percentage of germination and growth of mung beans (Vigna radiata). The research was conducted by making 3 (three) replications of each Treatment. Treatment A (application of A. conyzoides  leaf biomass to the planting media), Treatment B (used I. cylindrica planting media), and Control Treatment. Anova test and Tukey HSD test were conducted using R-Studio. The results showed that Treatments (A) and (B) reduced the success of mung bean germination compared to the control (97%), with A at 60% and B at 50%. The changes in leaf number and root length are very noticeable compared to plant height.  The allelopathic effect was stronger in A than B. Biomass of A. conyzoides  and used media of I. cylindrica has the potential to inhibit germination and early growth of mung beans.
