UPSC CSE Prelims 2010

Other than Jatropha curcas, why is Pongamia pinnata also considered a good option for the production of bio-diesel in India?

  1. Pongamia pinnata grows naturally in most of the arid regions of India.
  2. The seeds of Pongamia pinnata are rich in lipid content of which nearly half is oleic acid.

Which of the Statements given above is, are correct?

EXPLANATION

Correct Option (c)

Statement 1: Pongamia pinnata, also known as Karanj, is a hardy and drought-resistant tree species. It grows naturally across many arid and semi-arid regions of India and is well-adapted to poor, saline, or degraded soils. This adaptability makes it suitable for large-scale cultivation on marginal lands without competing with food crops.

Statement 2: The seeds of Pongamia pinnata are rich in lipid content. A significant proportion, approximately half, of this lipid content is oleic acid, which is a monounsaturated fatty acid. This specific fatty acid profile is highly desirable for the efficient production of high-quality biodiesel.

Incorrect Options

Options (a) and (b) are incorrect because both Statement 1 and Statement 2 are factually accurate and relevant to the suitability of Pongamia pinnata for biodiesel production.

Option (d) is incorrect as both given statements are correct, making the option 'Neither 1 nor 2' invalid.
