A farmer uses urea in a pea crop. Is he correct or not? Give reason.

Explanation

**Step-by-Step Solution:**

1. **Identify the Crop**: The question mentions a pea crop. Peas are classified as leguminous plants.

2. **Understand the Role of Leguminous Plants**: Leguminous plants, such as peas, have a symbiotic relationship with nitrogen-fixing bacteria (like Rhizobium) that live in their root nodules. These bacteria convert atmospheric nitrogen into a form that plants can use for growth.

3. **Consider the Use of Urea**: Urea is a nitrogenous fertilizer that provides nitrogen to plants. However, since pea plants already have a mechanism to obtain nitrogen through their symbiotic relationship with nitrogen-fixing bacteria, additional nitrogen from urea is unnecessary.
