It necessarily requires transporting straw to an external bioenergy plant. Which of the statements given above is/are correct?

  1. 1 and 2 only
  2. 2 and 3 only
  3. 1 and 3 only
  4. 1, 2 and 3

Answer

Correct Answer

1 and 2 only

Explanation

Statements 1 and 2 are correct: in-situ management treats residue on the field, and the Happy Seeder enables sowing wheat while retaining and incorporating paddy straw. Statement 3 describes an ex-situ pathway, in which residue is collected and transported for another use. In-situ and ex-situ are complementary but distinct approaches.
