Question

What is/are the advantage/advantages of zero tillage in agriculture ? Select the correct answer using the code given below:

  1. 1.

    Sowing of wheat is possible without burning the residue of previous crop.

  2. 2.

    Without the need for nursery of rice saplings, direct planting of paddy seeds in the wet soil is possible.

  3. 3.

    Carbon sequestration in the soil is possible.

Options

a

1 and 2 only

b

2 and 3 only

c

3 only

d

1, 2 and 3

Answer

Explanation

Zero tillage (no-till farming) is a conservation agricultural technique. It allows farmers to use specialized seed drills (like the Happy Seeder) to sow wheat directly into the unburned stubble of the previous rice crop (Statement 1 is correct). Direct Seeded Rice (DSR) techniques bypass the need to raise a nursery and transplant seedlings, allowing seeds to be sown directly into wet or dry soil (Statement 2 is correct). By not disturbing the soil, the oxidation of soil carbon is minimized, facilitating carbon sequestration (Statement 3 is correct). > One-line conceptual takeaway: Zero-tillage preserves soil integrity, enabling direct sowing and carbon sequestration while mitigating stubble burning. Answer: (d).
