[30] WebLeucaena leucocephala is a prolific seed producer and it also resprouts after its stems are cut or damaged. Leaves have a high nutritive value (high palatability, digestibility, intake, and crude protein content), resulting in 70-100% increase in animal live weight gain compared with feeding on pure grass pasture. In Agroforestry, many people use and promote Leucaena as a source of biomass and animal fodder. (2008). 0000220153 00000 n Livestock feed should not contain more than 20% of L. leucocephala, as the mimosine can cause hair loss and stomach problems. Habit: shrub or small tree growing up to 16 feet in height. In Peninsular Malaysia, the sources of raw material for the wood composite industry are mainly wood residues and rubberwood.

Improved varieties such as K636 encourage efforts to harvest lumber and paper pulp on a large plantation basis, with clear 30-cm boles on 14-m trees in 8 years. Continuous cutting will eventually kill larger trees. Many such hybrids are under evaluation at the University of Hawaii (Sorensson and Brewbaker 1994). It is interesting to note that genetic improvements need to be done via breeding programs in the near future to produce maximum yields that are comparable to the yield potential of these species under optimum conditions in Malaysia. This fact sheet is adapted from The Environmental Weeds of Australia by Sheldon Navie and Steve Adkins, Centre for Biological Information Technology, University of Queensland.
If available, you can collect seeds from dry pods on a nearby tree. It is also planted as a windbreak, a garden ornamental and as an urban shade tree. In Agroforestry Systems, its rapid growth and natural resilience to trimming make it an ideal support plant, providing benefits to the soil and neighboring plants.

L. leucocephala tolerates fast fires and can regrow after being burned to the crown by slower fires. The use of L. leucocephala as an agroforestry species continues to increase its spread and it is from such plantings that it often spreads to degraded lands, livestock pastures, forest plantations and wild vegetation areas. The analysis of variance (ANOVA) indicated highly significant difference for ratios (MOE, IB, TS and WA) and resins (MOE, MOR, IB, TS, and WA). DOI: 10.15376/biores.6.1.464-476.

The genus name Leucaena comes from the Greek words leuc meaning white and caen meaning new or recent, and refers to the whitish flowers this tree produces each year. It grows well only in subhumid or humid climates with moderate dry seasons of up to 6-7 months. Controlling the weed before it seeds will reduce future problems.

The foliage is remarkably similar to that of the mimosa (Albizia julibrissin), but the foliar gland of the lead tree, if present, is located on the rachis of the leaf between the lowermost pair of pinnae, while that of the mimosa is located near the base of the petiole. They are alternately arranged along the stems and borne on stalks (petioles) 2-5 cm long. Even though by performance there was an increment of IB as resin content increased, resin contents of 8% and 10% did not show significant IB difference. However, regrowth is rapid and most trees recover sufficiently to produce large crops of seeds. Fig. The legume is promoted in several countries of Southeast Asia (at least Burma, Cambodia, Indonesia, Laos,[11] and Thailand), most importantly as a source of quality animal feed, but also for residual use for firewood or charcoal production. 0000001549 00000 n *c/ "="WrKI{}}.W5QDD;WFW:K l4QXh*5UwPTEve}[;p)H4y0|`6;T8gb( !E5NOD*L"?dx}|/Ld?svN$*-^ Consistent follow-up work is required for sustainable management. keys.lucidcentral.org.
