Pongamia pinnata: Is there any alternative crop to Jatropha Curcus? The answer is yes. Pongamia is another oil plant tree, which can provide you a higher yield per Ha, but one can expect the yield only after 4 to 7 years!
It is a deciduous tree that grows to about 15-25 meters in height with a large canopy that spreads equally wide. The leaves are a soft, shiny burgundy in early summer and mature to a glossy, deep green as the season progresses. Small clusters of white, purple, and pink flowers blossom on their branches throughout the year, maturing into brown seed pods. The tree is well suited to intense heat and sunlight and its dense network of lateral roots and its thick, long taproot make it drought tolerant. The dense shade it provides slows the evaporation of surface water and its root structures promote nitrogen fixation, which moves nutrients from the air into the soil. Withstanding temperatures slightly below 0C to 50C and a minimum annual rainfall of 500 mm, 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.
Trees of ten reach adult height in 4 or 5 years, bearing at the age of 47 years. A single tree is said to yield 990 kg seed per tree, indicating a yield potential of 9009000 kg seed/ha. Pongamia seeds contain 30-40% oil. Pongamia pinnata belongs to the family sp. (Papilionaceace) are mere species viz. Pongamia glabra also exists.
Pongamia seed oil as a bio- fuel has physical properties very similar to conventional diesel. Emission properties, however, are cleaner for Bio-fuel than for conventional diesel.
