The present study had as objective, to realize the prelyminar observations of the Canavalia ensiformis behaviour in the Cauca's Valley. Observations were made about phytopatologics and entomologics, morphologics and phenologics aspects, agronomic bahevior, nodulation and the yield's components for 3 distances of sowing. C. ensiformis presents 3 growth's habits: determinated shrub, shrub habit with short guide and indeterminated habit with long guide, climbing. C. ensiformis presents one vegetative of 69 days and one reproductive phase of 122 days. The pests insects with more damage's potential are: Corythuca gossypii, Anticarsia gemmatalis y Caryedes grammicus, this later the first report in the world. Virosis, anthracnosis and powdery mildew were the diseases with higher incidence. The virus was named CMV, one potyvirus, which constitute the 5 thin the world for Canavalia. The distance 1 x 0.6 m was the best treatment among the evaluated, and the number of pods for plant is the principal component of the yield.
