Evaluation of allelopathic potential of selected plant species on Parthenium hysterophorus

Abstract

The phytotoxicity of shoot leachates of selected plant species was assessed on germination, and on shootcut and seedling bioassays of Parthenium hysterophorus. Shoot leachates of selected plant species were effective in inhibiting germination of Parthenium seeds, with Azardirachta indica the most effective. Shoot growth was inhibited most, and shoots damaged the most, by leachates of Solanum nigrum.
