(v) Seeds are mixed before sowing.

Options

B. (i) and (iii) only
C. (iii) and (v) only
D. (iv) and (v) only

Answer

To solve the question regarding which statements are true in the case of intercropping, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Intercropping**:
- Intercropping is a method of growing two or more crops in the same field at the same time. This practice can enhance productivity and resource use efficiency.

2. **Evaluating Statement (i)**:
- **Statement**: Crops are grown in definite pattern of rows.
- **Analysis**: In intercropping, crops are indeed grown in a specific arrangement, typically in alternating rows. This statement is **true**.

3. **Evaluating Statement (ii)**:
- **Statement**: Fertilisers cannot be applied easily to different crops.
- **Analysis**: In intercropping, because crops are arranged in rows, it is possible to apply fertilizers to each crop effectively. This statement is **false**.

4. **Evaluating Statement (iii)**:
- **Statement**: Crops can be harvested and threshed separately.
- **Analysis**: Since different crops can be planted in intercropping, they can be harvested and threshed at different times. This statement is **true**.

5. **Evaluating Statement (iv)**:
- **Statement**: Spraying of pesticides for separate crops is not possible.
- **Analysis**: It is possible to spray pesticides on separate crops in intercropping, as they are arranged in rows. This statement is **false**.

6. **Evaluating Statement (v)**:
- **Statement**: Seeds are mixed before sowing.
- **Analysis**: In intercropping, seeds are not mixed; they are sown in a specific pattern. This statement is **false**.

7. **Conclusion**:
- The true statements are (i) and (iii). Therefore, the correct answer is that the true statements in the case of intercropping are:
- (i) Crops are grown in definite pattern of rows.
- (iii) Crops can be harvested and threshed separately.

### Final Answer:
The correct answer is that statements (i) and (iii) are true regarding intercropping.
