2. Albizia procera for Reforestation and Agroforestry
Summery
Albizia procera is a large, fast-growing tree
that occurs on many different sites. This
species provides wood for a variety of
purposes, nutritious fodder for livestock and
shade for tea plantations. It is an important
reforestation and agroforestry species. It is
commonly called locally White siris, Sada
Koroi etc.

14. Uses
Agroforestry
 Likely to affect nutrient cycling as the species
is a nitrogen fixer.
 Natural regeneration provides small timber,
fuelwood, charcoal, fodder or shade.
 Seedlings are planted in family forests or
home gardens.
 Albizia procera can be cultivated as shade for
tea plantation.
 It is protein-rich fodder.

15. Uses
Medicinal
• Bark-boiled water with table salt is
prescribed to expel threadworms.
• Bath with the same water is given for
scabies.
• Extract is used to wash the anus thrice a
day until the anal fissure is cured.
• A paste is of bark is applied on the
infected skin twice a day until the
leprosy is cured.

16. Uses
Wood
Durable, strong and resistant to termites
The wood is light- to chocolate-brown
with light and dark bands.
It is difficult to saw due to interlocking
grain and has a specific gravity of 0.6-0.9.
Considered a promising source of pulp for
high-quality paper.

19. Natural Enemies
Diseases
o Seedling wilt caused by Fusarium oxysporum
o Leaf spot caused by Colletotrichum dematium and Cercospora albiziae
o Pustules on leaflets caused by Ravenelia clemensiae
o Bark and stem cankers caused by Fusarium solani
o Root rot caused by Ganoderma lucidum

20. Natural Enemies
Insect
 Seed weevils such as Bruchidius bilineatopygus
 Root knot nematodes such as Meloidogyne spp.
 Hemipterous insect such as Oxyrhachis tarandus
 Termite such as Coptotermes curvignathus and
Ancistrotermes amphidon.
 Stem borer such as –
Ascotis selenaria Hyposidra successaria
Eurema blanda Rhesala imparata
Eurema hecaba Rhesala inconcinnalis
Cusiala raptaria Rhesala moestalis

21. Symbiosis
Albizia procera forms symbiotic
association with Rhizobium
bacteria enabling it to fix nitrogen
and thrive on infertile soils. The
application of phosphorus
fertilizer can improve nodulation
and nitrogen fixation, particularly
on infertile soils.

22. Limitations
Because of its aggressive growth white Siris (Sada Koroi) may
be a potential weed. This is particularly true in the many
countries, where white siris (Sada Koroi) grows faster than
many native species.
