Options

A. Hybridisation and production of new varieties
B. More income
C. Less disease
D. Less difficulty in selling the fruits

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why fruit growers cultivate two or more varieties of fruits in their orchards. This involves recognizing the benefits of growing multiple varieties.

2. **Identifying the Benefits**: The benefits of growing multiple varieties can include:
- Hybridization and production of new varieties.
- Increased income.
- Reduced disease incidence.
- Easier selling of fruits.

3. **Exploring Multi-Cropping**: The practice of growing two or more varieties is known as multi-cropping or intercropping. This technique can lead to:
- Greater overall yield.
- Efficient use of agricultural inputs (like water and nutrients).
- Reduced pest and insect attacks.

4. **Mechanism of Pest Control**: When farmers plant a main crop (host plant) alongside other varieties (trap plants), the trap plants attract pests away from the host plants. This method helps in reducing pest damage to the main crop.

5. **Evaluating the Options**:
- Hybridization and production of new varieties: This is not the primary reason for growing multiple varieties.
- More income: This is a potential benefit, but it is contingent on other factors like disease management.
- Less disease: This is a direct benefit of using multiple varieties to reduce pest attacks.
- Less difficulty in selling fruits: This is not a direct benefit of growing multiple varieties.

6. **Conclusion**: Among the given options, the most appropriate answer is that fruit growers grow two or more varieties to have **less disease**, which in turn can lead to increased income.

**Final Answer**: Fruit growers grow two or more varieties of fruits in their orchards to have **less disease**.
