Summary: | Allelopathic effect of the cover crops Tradescantia zebrina Shunltz (cucaracha) and Commelina
diffusa Burm. F. (canutillo) were evaluated on Coffea arabica Lin. seeds Caturra Rojo variety. Germination
tests were carried out “in vitro” and it was evaluated the root longitude, percentage of total germination and
period of germination, as well as the height of the plant and the emergency percentage for the incorporation
tests to the soil. It was also carried out, to both over crops, the preliminary chemical qualitative characterization.
The results showed that the extracts of T. zebrina and of C. diffusa stimulated the “in vitro” germination and
growth of C. arabica at different concentration levels. The incorporation to the soil of the extracts of C. diffusa
stimulated the development of the plants of C. arabica, in a significant way, that supposes a considerable
advantage in that concerns to the employment of these cover crops, when not implying noxious effects beside
all the benefits implied when using cover crops. These last ones go from the protection and improvement of
the properties of the soil, to the control of the spontaneous flora in the coffee agroecosystems. |
