The best way to increase the yield of crop :-

Options

A. To sow seed of high yielding and disease resistant varieties.
B. By better management practice
C. To increase acrage under cultivation
D. To remove weeds from fields

Answer

To solve the question "The best way to increase the yield of crop," we will evaluate the provided options step by step.

### Step-by-Step Solution:

1. **Evaluate the Options**: The question provides four options for increasing crop yield:
- A. Sow seeds of high yielding and disease-resistant varieties
- B. Better management practices
- C. Increase the acreage under cultivation
- D. Remove weeds from the field

2. **Analyze Option A**:
- Sowing seeds of high yielding and disease-resistant varieties is a well-established method in agriculture.
- High yielding varieties (HYVs) are specifically bred to produce more grain or fruit per plant compared to traditional varieties.
- Disease-resistant varieties help ensure that crops are less affected by diseases, leading to better overall yield.

3. **Analyze Option B**:
- Better management practices can improve the efficiency of farming but do not inherently increase the yield of the crops themselves.
- This may include practices like crop rotation, irrigation management, and fertilization, which can optimize yield but do not guarantee an increase.

4. **Analyze Option C**:
- Increasing the acreage under cultivation means farming on more land.
- While this can lead to more total production, it does not necessarily increase the yield per unit area. Yield is defined as the amount produced per unit area, so this option is not directly related to increasing yield.

5. **Analyze Option D**:
- Removing weeds can help crops grow better by reducing competition for nutrients, water, and light.
- However, this action alone does not directly increase the yield; it simply helps maintain the current yield potential.

6. **Conclusion**:
- After analyzing all options, the best way to increase the yield of crops is to **sow seeds of high yielding and disease-resistant varieties** (Option A). This approach directly targets the yield potential of the crops and ensures better resilience against diseases.

### Final Answer:
The best way to increase the yield of crops is to **sow seeds of high yielding and disease-resistant varieties**.
