Abstract :In a laboratory experiment, the herbicidal potential of poplar leaves was evaluated against six weed species that are Avena fatua, Phalaris minor, Rumex dentatus, Parthenium hysterophorus, Lepidium sativum and Silybum marianum. Aqueous extract of Populus nigra leaves’ powder obtained at 10, 15, and 20 g concentrations were used as treatments for testing germination and seedling growth responses of the target weed species. Germination and growth of all six weeds species were reduced with increasing concentration of the leaves.  Results suggests the potential role of this plant’s extracts in the management of weeds; however, more work is needed to be conducted for identification of the allelochemicals present in poplar plant which exhibit inhibitory activities against seed germination and growth parameters of test plants.
