Hi
Pongamia cultivation is simple.
Seeds, remaining viable for sometime, require no special scarification. Direct sowing is usually successful. Seedlings transplant easily from the nursery after about a year. Root suckers are rather plentiful as well. It is a rapid-growing coppice species that can be cloned.
Probably ranges from Tropical Dry to Moist through Subtropical Dry to Moist Forest Life Zones. Withstanding temperatures slightly below 0°C to 50°C and annual rainfall of 5–25 dm, the tree grows wild on sandy and rocky soils, including oolitic limestone, but will grow in most soil types, even with its roots in salt water.
Harvesting
Pods are collected and shells removed by hand. Grown in 30-year rotations for fuel in West Bengal.
Yields and Economics
Trees of ten reach adult height in 4 or 5 years, bearing at the age of 4–7 years. A single tree is said to yield 9–90 kg seed per tree, indicating a yield potential of 900––9000 kg seed/ha, 25% of which might be rendered as oil (assuming 100 trees/ha). In general, Indian mills extract 24–27.5% oil, village crushers, 18–22% oil.
