With Melinis minutiflora – low palatability may lead to dominance over companion species. With Panicum maximum – low palatability may lead to dominance over companion species. Pudoc Scientific Publishers, Wageningen, the Netherlands. A vigorous, creeping, twining or trailing, short-lived perennial herb, up to several metres long, forming a tangled mass of foliage cm thick, with densely pilose stems with long rust-coloured hairs.

Pod linear-oblongoid, cm x 3. Seeds per podcompressed squarish, mm long, yellowish or reddish-brown. Grazing legume, green manure, pioneer legume and cover crop. Mainly used as cover crop in tropical tree plantations over the past years. Recognised as a valuable pioneer species, reducing erosion and improving soil fertility.

Despite generally low palatability, cattle graze calopo during the latter part of the dry season in tropical Asia and Africa.

Grows on a wide range of soil jucunoides, but prefers clay soils with pH 4. In tropical America, grows well on acid soils with high Al saturation. Poor tolerance of salinity. Adapted to the hot, wet tropics with annual rainfall exceeding 1, mm where individual plants will persist for years. Poor drought tolerance but plants will regenerate from seed.

Good tolerance of inundation.

Calopogonium mucunoides

Prefers humid-tropical, low elevations but will grow up to altitudes of 2, m asl. DM yield, root growth and nodulation decrease markedly as light transmission decreases. Less shade tolerant than C. Calopo is self-fertile and seeds freely. May act as an annual in seasonally dry environments. It is not tolerant of frequent severe defoliation but can be cut at intervals of months. Recovers slowly from defoliation.


In grazing systems, best results are achieved with rotational grazing at week intervals. When broadcast, seed should be spread on the soil surface and then rolled to improve establishment. Calopo is promiscuous in its rhizobia requirements, but cowpea inoculant can be used in sterile soils.

Can also be established into cultivated strips prepared using disc harrows. Established well when broadcast into upland rice following the final weeding.

Mid-season plantings may reduce rice yields. Will dominate cover crop mixtures during early growth due to its rapid establishment, but is suppressed by shading as other species develop.

Commonly reported as a volunteer legume in humid-tropical native pastures. Excellent compatibility with tall, erect grasses such as Rhodes grass Chloris gayanapangola grass Digitaria eriantha and setaria Setaria sphacelatabecause it is little eaten. However, its low palatability can lead to calopo dominance. Sometimes oversown into signal grass Brachiaria decumbens pastures in Brazil.

As cover crop in tree plantations in southeast Asia, often planted in a species mixture with one or more of the species C. Affected by viruses, including cowpea severe mosaic comovirus geminiviruses, cxlopogonium Centrosema mosaic potexvirus, but these rarely significantly impede growth. Susceptible to the root-knot nematode, Meloidogyne javanica.

Can become a localised weed mucunoies humid-tropical environments. Has invaded tropical ecosystems in northern Australia and is listed as a weed in the Philippines, Malaysia and Indonesia.

Generally regarded as being of low-moderate palatabilitybut considerably more palatable than C. Cattle in confinement have refused to consume freshly cut material, eating the legume only if wilted. In other situations, the legume is consumed after cattle become accustomed to it.


However, in the state of Minas Gerais in Brazil, where pastures may naturally contain a significant amount of the legumegrazing cattle have been observed consuming plants without any problems.

DM yields generally decline over time with repeated cutting or grazing, and yields may be substantially lower in the second and third years after planting. When used as an improved fallowC. In Brazil, cattle grazing signal grass Brachiaria decumbens and B.

The legume percentage decreased linearly from the 1st mucunodes the 3rd year. There are no breeding programs for calopo. A large germplasm collection was assessed by Pizarro and Carvalhowho mucunoidee significant variation in DM productivity, dry season leaf retention, nutritive value IVDMDseed yield and natural habitat collection site.
