GOMEZ, I et al. Naturalized legumes in the Cauto Valley, Cuba. Pastos y Forrajes [online]. 2010, vol.33, n.4, pp. 1-1. ISSN 0864-0394.

With the objective of prospect and collect the naturalized legumes for livestock production usage in the Cauto Valley, Cuba, two searches were made in representative zones of the region. The first search was conducted in the territory located west of Bayamo city, where there are different soils and rainfall regimes, and the second one on soils affected by salinity. In prospection number 1 the presence of 17 genera was determined and within them a total of 22 species, among which the following prevailed: Galactia spiciformis, Centrosema molle, Desmodium triflorum and Teramnus uncinatum; the existence of an important number of species was also known on vertisol soils with deficient drainage, which edaphic grouping constitutes the most extended in the region, and on the other hand, the associability degree of each legume with other species of the spontaneous vegetation present in the search areas, was characterized. In prospection number 2 four and five genera were found on areas with weak and moderate fertility levels, respectively, and Desmanthus virgatus stood out due to the abundance in the number of individuals. It is concluded that under the conditions these prospections were made, there is a rich potential of naturalized legumes with multiplication and usage possibilities in the region.
