Some plants may produce secondary compounds with potential beneficial in agricultural management, as an alternative to use in seed treatment however, may present some type of allelophathy inhibitory to the development of certain crops of interest. Therefore, the objective of this work was to evaluate the effects allelopathic of water extract of basil (Ocimum basilicum L.) and aloe (Aloe vera L.) at different concentrations in the germination of the seeds of the arugula (Eruca sativa L.). The concentration for the aqueous extract was 20% (weight / volume) and from this the other concentrations were obtained. The treatments used were the concentrations of 25, 50, 75 and 100% of extracts from aloe and basil extracted by the method of cold turbolise, and witness water autoclaved. The effects of the extracts the experiment was conducted in delineation entirely randomed, with 6 repetitions, being the experimental unit composed by a box Gerbox® with 50 seeds of arugula were assessed for the variables: index of speed germination, percentage of germination, length of radicle and aerial part. The extracts of basil and aloe have any substance or an association of secondary compounds with effect allelopathic that favored the development of the aerial part, influenced negatively on development of the radicle, however, showed no effect allelopathyc in the germination of the seeds of the arugula.
