Options

A. Gramineae
B. Leguminosae
C. Solanaceae
D. Compositae

Answer

**Step-by-Step Solution:**

1. **Understanding Manure**: The first step is to define what manure is. Manure is organic matter that can come from both plant and animal sources. It is used to enrich soil and improve its fertility.

2. **Types of Manure**: There are different types of manure:
- **Farmyard Manure**: This type is derived from animal waste, such as cow dung and urine.
- **Compost**: This is made from decomposed organic matter, including both plant and animal waste.
- **Green Manure**: This is the focus of the question. Green manure is specifically derived from plants.

3. **Identifying Green Manure Plants**: Green manure plants are primarily leguminous crops. Leguminous plants are those that belong to the family Fabaceae, which includes beans, peas, and clover.

4. **Importance of Leguminous Crops**: Leguminous crops are particularly valuable for green manure because they have nitrogen-fixing bacteria in their root nodules. These bacteria convert atmospheric nitrogen into forms that plants can absorb, such as nitrites and nitrates.

5. **Benefits of Green Manure**: When leguminous crops are used as green manure and they decompose, they enrich the soil with nitrogen and other nutrients, making the soil more fertile.

6. **Conclusion**: Therefore, the correct answer to the question "Green manure plants belong to" is that they belong to the leguminous family of plants.

**Final Answer**: Green manure plants belong to the leguminous family (Fabaceae).
