Question

For cultivation of wheat crop in clay loam soil, arrange the farm implements activity in field. A. MB. Plough B. Seed drill C. Sprayer D. Disk harrow E. Combine Choose the correct answer from the options given below:

• A. A, C, D, B, E
• B. B, E, A, D, C
• C. C, A, E, B, D
• D. A, D, B, C, E

Hint:

Standard crop cultivation sequence: \[ \boxed{ \text{Primary tillage} \rightarrow \text{Secondary tillage} \rightarrow \text{Sowing} \rightarrow \text{Plant protection} \rightarrow \text{Harvesting} } \] Corresponding implements: \[ \boxed{ \text{MB Plough} \rightarrow \text{Disk Harrow} \rightarrow \text{Seed Drill} \rightarrow \text{Sprayer} \rightarrow \text{Combine} } \]

Answer 1

The Correct Option is D

Concept: Farm operations in crop cultivation follow a systematic sequence to ensure:
• Proper seedbed preparation
• Efficient sowing
• Crop protection
• Efficient harvesting For wheat cultivation, field operations generally proceed in the following stages:
• Primary tillage
• Secondary tillage
• Sowing
• Crop protection
• Harvesting Each implement performs a specific agricultural operation.

Step 1: Understanding MB Plough operation. MB plough means: \[ \boxed{\text{Mould Board Plough}} \] It is used for:
• Primary tillage
• Deep soil turning
• Burial of weeds and residues Primary tillage is always the first field operation. Hence: \[ \boxed{ \text{MB Plough comes first} } \] Thus: \[ A \rightarrow \text{First} \]

Step 2: Understanding Disk Harrow operation. Disk harrow is used after ploughing for:
• Clod breaking
• Soil pulverization
• Seedbed preparation This is a secondary tillage operation. Therefore: \[ \boxed{ \text{Disk harrow follows MB plough} } \] Thus: \[ D \rightarrow \text{Second} \]

Step 3: Understanding Seed Drill operation. Seed drill is used for:
• Sowing seeds uniformly
• Maintaining seed spacing
• Proper seed depth placement Sowing is done only after proper seedbed preparation. Hence: \[ \boxed{ \text{Seed drill comes after tillage operations} } \] Thus: \[ B \rightarrow \text{Third} \]

Step 4: Understanding Sprayer operation. Sprayer is used during crop growth for:
• Weed control
• Pest control
• Fungicide application This operation occurs after crop establishment. Thus: \[ C \rightarrow \text{Fourth} \]

Step 5: Understanding Combine operation. Combine harvester is used at maturity stage for:
• Harvesting
• Threshing
• Cleaning grains Harvesting is the final field operation. Hence: \[ E \rightarrow \text{Last} \]

Step 6: Writing the final sequence. Thus the proper order becomes: \[ A \rightarrow D \rightarrow B \rightarrow C \rightarrow E \] Therefore: \[ \boxed{ A,\; D,\; B,\; C,\; E } \]

Step 7: Comparing with the given options. Option (A): Incorrect sequence because sprayer cannot precede tillage and sowing. Hence: \[ \boxed{\text{Option (A) is incorrect}} \] Option (B): Incorrect because sowing and harvesting cannot occur before tillage. Hence: \[ \boxed{\text{Option (B) is incorrect}} \] Option (C): Completely incorrect sequence. Hence: \[ \boxed{\text{Option (C) is incorrect}} \] Option (D): Matches the correct agricultural operation sequence. Hence: \[ \boxed{\text{Option (D) is correct}} \] Final Conclusion: The correct sequence of field operations is: \[ \boxed{ A,\; D,\; B,\; C,\; E } \] Hence the correct answer is: \[ \boxed{ (D)\ A,\; D,\; B,\; C,\; E } \]
