The radite (Hypochaeris chillensis Hieron), native from Brazil, deserves investigation not only for its nutritional potential as medicinal species. The objective of this work was to verify the influence of different aqueous extract concentrations of Jatropha curcas (Pinhão Manso) leaves in radite cultivation. We used jatropha extract concentrations of 0% (control), 5, 10, 20, 40 and 80%, to perform the treatments, considering as pure extract 200 g of green leaves of jatropha in one litre of distilled water. The seeds were sown in trays specific for vegetable seedling production, a manual sprinkler system was used. With the increasing concentration of the aqueous extract of the leaves of Jatropha curcas, there was a decreasing tendency in the leaf number, plant height, root size and dry mass, proving the allelopathic effect of Jatropha curcas leaf extract on radite cultivation.
