Question

Match List-I with List-II.

List-I (Field operation)	List-II (Equipment used)
(A) Intercultural operation	(I) Rotavator
(B) Deep ploughing	(II) Cultivator
(C) Soil pulverization	(III) Sub-soiler
(D) Conservation tillage	(IV) Strip-till drill
(E) Soil Inversion	(V) MB plough

Choose the correct answer from the options given below:

• (A) - (I), (B) - (V), (C) - (II), (D) - (IV), (E) - (III)
• (A) - (IV), (B) - (I), (C) - (V), (D) - (III), (E) - (II)
• (A) - (II), (B) - (III), (C) - (I), (D) - (IV), (E) - (V)
• (A) - (IV), (B) - (II), (C) - (I), (D) - (V), (E) - (III)

Hint:

Match each operation to the implement whose basic design purpose is to achieve exactly that effect on soil.

Answer 1

The Correct Option is C

Step 1: Intercultural operations are the light tillage jobs done between crop rows after sowing, mainly to remove weeds and loosen the surface soil. A cultivator, with its tines, is the standard implement for this, so (A) matches (II).

Step 2: Deep ploughing means breaking up a hard or compacted layer well below normal plough depth. A sub-soiler has a strong narrow shank to go deep and shatter this hard pan, so (B) matches (III).

Step 3: Soil pulverization means breaking clods into a fine, crumbly tilth. A rotavator uses power-driven rotating blades that chop and pulverize soil finely in a single pass, so (C) matches (I).

Step 4: Conservation tillage aims to disturb as little soil as possible while still placing seed properly. A strip-till drill tills and sows only narrow strips, leaving the rest of the field undisturbed, so (D) matches (IV).

Step 5: Soil inversion means turning the furrow slice completely upside down, which is the classic job of a mould board (MB) plough, so (E) matches (V).

Putting it together, (A)-(II), (B)-(III), (C)-(I), (D)-(IV), (E)-(V), option 3.
