Natural Regeneration :

Natural Regeneration:

• Regeneration is satisfactory with good soil conditions.

Artificial Regeneration:

• Siris can be raised easily by direct sowing and Nursery raised seedlings.

Seed Collection and Storage:

• Pods are collected from the tree April - May
• The pods are collected, dried in sun and seeds are extracted.
• The cleaned seeds are stored in gunny bags in a dry place for long period without losing the germinative capacity.
• Seed weight is 15000/kg.
• Germinative capacity is 47%
• Expected number of plant per kg. of seed is 7285.

Seed Treatment:

• The seeds are soaked in cold water for 24 hours before sowing.

Nursery Technique:

• The seeds are sown in mother bed during April and watered regularly till the germination takes place.
• Germination starts from within 10 days from sowing.
• The seedlings are transplanted to polybags when it attains 15-30 cm height.
• Weeding accelerates the growth of the plants.
• The seeds can also be directly sown in polybags of size 13 x 25 cm in April – May to obtain the plantable size seedlings by July.

Plantation technique :

Direct sowing :

• The species can be raised successfully by direct sowing in lines 1.5 m apart in July and September.
• This method can be adopted in hot dry region with less rainfall.

Nursery raised seedlings:

• Planting out is carried out during July in 30 cm3 pits,
• Under dry conditions, pit size of 60 cm3 with a spacing of 3x3 m to 5m x 5m
• Planting should be carried out after the commencement of monsoon

Care & Disease Control :

• Two weedings are carried out in the first and one in second year
• Soil and water conservation measures to be adopted. 

Irrigation :

For proper growth and survival, it is necessary to give one or two waterings after planting. This is specifically required in arid regions. Irrigation after planting is not a prerequisite in areas having sufficient soil moisture and precipitation. Higher survival rate and better rate of growth is reported when soil and water conservation measures are also adopted.

Recommended Harvest :

• 15 – 20 years.

Yield :

• Approximately 160 to 170 tons/ha*

*Subject to varry according to site factors.

Agro Forestory :

• The tree utilizes the subsoil moisture and nutrients not available to plants and protects them from hail and rainstorms.

Shade or shelter:

• A. odoratissima has been extensively planted as a shade tree in tea and coffee plantations.

Major uses :

Wood:

• It is a valuable constructional timber and cabinet wood.
• It is used for beams, rafters, planking: carts, oil mills, ploughs, cooperages and decorative work and paneling
• Leaves are good fodder for cattle.
• It makes a good avenue tree with sweet scented flowers.
