A laboratory experiment was conducted to investigate allelopathic potential of water extract of rice-stubble leachate on certain oil-yielding crops (mustard, sesamum and sunflower). A wide range of rice-stubble concentration (i.e. 5, 10, 15, 20, 25, 30 and 40) were prepared and used for testing of seedling growth parameters (Length, fresh and dry weight of shoot and root) of oil-yielding test crop seedlings. The experimental results found that the different seedling growth parameters were reduced with increased concentration of rice-stubble leachate in compared to control set. Root growth was more sensitive than shoot growth with increase of leachate concentration of rice-stubble. This experimental results show the existence of several bioactive compounds (i.e. allelochemicals) in rice-stubble. These bioactive compounds might serve as a source of natural herbicides.
