Sohan is growing rice in his field this season. He is worried that his soil will lose nitrogen by the end of the season. What other crop can Sohan grow along with rice in order to avoid this problem?

Options

A. Wheat
B. Groundnut
C. Grass
D. Barley

Answer

To address Sohan's concern about nitrogen depletion in his soil after growing rice, he can consider the following steps:

### Step-by-Step Solution:

1. **Understanding the Problem**: Sohan is worried that growing rice will deplete nitrogen in the soil. Rice, being a heavy feeder, consumes a lot of nitrogen, which is essential for its growth.

2. **Exploring Crop Rotation**: One effective way to manage soil nutrients is through crop rotation. This involves alternating the crops grown in a field across different seasons.

3. **Choosing the Right Crop**: To replenish nitrogen in the soil, Sohan should consider planting a leguminous crop after the rice season. Leguminous plants have a unique ability to fix atmospheric nitrogen through symbiotic bacteria present in their root nodules.

4. **Selecting Groundnut**: Among the various leguminous crops, groundnut (also known as peanut) is a suitable choice. It not only grows well but also helps in fixing nitrogen in the soil, thus replenishing the nitrogen levels that were depleted by the rice.

5. **Conclusion**: By planting groundnut after rice, Sohan can effectively maintain the nitrogen levels in his soil, ensuring better soil health and productivity for future crops.

### Final Answer:
Sohan can grow groundnut along with rice to avoid nitrogen depletion in the soil.
