Question

Match List I with List II 

 

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

Hint:

Remember: "Chisel = Subsoil," "Disc = Deep Ploughing," and "Rotary = Pulverization." Breaking down tillage tool functions in these simple terms helps avoid confusion.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Tillage implements are categorized as primary or secondary based on their action, working depth, and soil manipulation characteristics.

Step 2: Detailed Explanation:
Let us match the functions of the implements:
- Chisel plough: This is a deep primary tillage implement designed to break up hard pan layers and shatter the subsoil without soil inversion. (A - IV)
- Rotary plough (Rotavator): This uses rotating blades to cut, mix, and pulverize light to moderate soils in a single pass. (B - III)
- Disc plough: This is used for primary deep ploughing, particularly in hard, dry, stony, or sticky soils where moldboard ploughs cannot perform well. (C - I)
- Harrows: These are secondary tillage tools used to prepare fine seed beds, break remaining surface clods, and uproot young weeds. (D - V)
- Cultivators: These are used to stir and cultivate the soil, break surface crusts, destroy emerging weeds, and facilitate intercultural operations. (E - II)
Therefore, the correct matching is A - IV, B - III, C - I, D - V, E - II.

Step 3: Final Answer:
The matching sequence corresponds to Option (D).
