Allelochemics impacts of leaf extracts from Vernonia amygdalina and Chromolaena odorata on germination of rice
Allelopathy from invasive and medicinal weeds can affect crop establishment, yet species- and concentration-specific impacts on rice remain poorly quantified. This study evaluated the concentration-dependent allelopathic effects of aqueous leaf extracts of Vernonia amygdalina Delile and Chromolaena odorata (L.) R.M. Ki...
