Show answer
Answer: D. Statement 1 is correct: with zero tillage (for example the Happy Seeder), wheat can be sown straight into rice stubble without burning it. Statement 2 is correct: it allows direct seeding of rice without a nursery. Statement 3 is correct: not ploughing keeps carbon in the soil. So all three.
Watch for: Statement 2 seems about transplanting methods, but direct seeding is part of zero-till systems.
Why the other options are wrong
- A. Wrong because zero tillage also helps carbon sequestration.
- B. Wrong because zero tillage also avoids stubble burning.
- C. Wrong because statements 1 and 2 are also correct.
