Find out a set of common `N_(2)` fixing fodder plants

Options

A. Trifolium, Atropa
B. Withania, Abrus
C. Sesbania, Trifollum
D. Aloe,Gloriosa

Answer

To find a set of common nitrogen-fixing fodder plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Nitrogen Fixation**: Nitrogen fixation is the process by which certain plants convert atmospheric nitrogen (N₂) into a form that can be used by plants, such as ammonium (NH₄⁺), nitrate (NO₃⁻), or nitrite (NO₂⁻). This process is crucial for plant growth and soil fertility.

2. **Identify Nitrogen-Fixing Plant Families**: The primary family of plants known for nitrogen fixation is the Fabaceae family (also known as Leguminosae), which includes legumes. These plants have symbiotic relationships with nitrogen-fixing bacteria, such as Rhizobium, which reside in their root nodules.

3. **List Common Nitrogen-Fixing Fodder Plants**: Some common nitrogen-fixing fodder plants include:
- **Cyanodon dactylon** (Bermudagrass)
- **Trifolium spp.** (Clover)
- **Medicago sativa** (Alfalfa)
- **Sesbania spp.** (Sesbania)
- **Vigna unguiculata** (Cowpea)
- **Phaseolus spp.** (Beans)

4. **Select the Relevant Options**: From the options provided in the question, we can identify:
- **Cysbania** (likely referring to Sesbania) and **Tricholoma** (though Tricholoma is not a common nitrogen-fixing plant, it may have been confused with a similar name).
- The correct nitrogen-fixing plants from the options are **Sesbania** and **Trifolium**.

5. **Conclude the Answer**: Based on the identification of common nitrogen-fixing fodder plants, the set of common nitrogen-fixing fodder plants includes **Sesbania** and **Trifolium**.

### Final Answer:
The common nitrogen-fixing fodder plants are **Sesbania** and **Trifolium**.
