Natural Regeneration :
- Natural regeneration by seeds is not satisfactory.
Artificial Regeneration :
Seed collection and Storage :
- Ripe pods are collected in April - May.
- The pods are beaten up to extract seeds.
- The seeds can be stored in gunny bag for long time
- Seed rate 2100 – 3250/Kg.
- Germination Capacity is 25 – 70 %
- Plant Percent is 20-30
- The seeds remain viable for more than 5 years
Seed Treatment :
- Cold water treatment for 10 days gives 25 % germination.
- Hot water treatment for 5 days gives 30 % germination.
Nursery Technique :
- The seeds are sown in unshaded nursery bed in September – October.
- Beds are watered regularly.
- Germination starts in 12 days.
- The two leaf stage seedlings are pricked out in polybags and maintained in nursery.
- The seeds can also be directly sown in poly bags.
Plantation technique :
- 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.
- Planting should be carried out after the commencement of monsoon.
Care & Disease Control :
- Pruning should be done to develop a good crown structure
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.
Yield :

Other uses :
Medicine:
Bark has medicinal property . Fuel: The large pods as well as the wood are used for fuel.
Carbon stock :
0.078 tC/Tree
