(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:

Show Hint

Match each operation to the implement whose basic design purpose is to achieve exactly that effect on soil.
  • (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)
Show Solution

The Correct Option is C

Solution and Explanation

Work from the equipment side instead. A rotavator's spinning blades are known for producing a fine, powdery tilth, which is soil pulverization, so rotavator goes with (C).

A cultivator's spring or rigid tines are the normal tool for going between standing crop rows to cut weeds, which is intercultural operation, so cultivator goes with (A).

A sub-soiler's whole job is to go deeper than a normal plough to break compacted layers, matching deep ploughing (B).

A strip-till drill only loosens and sows a narrow strip and leaves the rest of the field undisturbed, which is conservation tillage (D).

An MB plough's mouldboard shape is specifically built to lift and flip the furrow slice over, which is soil inversion (E).

This gives the same matching from the other direction, (A)-(II), (B)-(III), (C)-(I), (D)-(IV), (E)-(V).

\[\boxed{(A)\text{-}(II),\ (B)\text{-}(III),\ (C)\text{-}(I),\ (D)\text{-}(IV),\ (E)\text{-}(V)}\]
