Natural Regeneration :
- Regeneration is satisfactory with good soil conditions.
- 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.
- The seeds are soaked in cold water for 24 hours before sowing.
- 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.
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 :
- 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 :
- 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.
Market details :
- Approximately Rs.3700 to Rs.4000/ton*
