The crop that would require minimum quantity of urea for its growth is

Options

A. blackgram
B. paddy
C. sugarcane
D. groundnut

Explanation

To determine which crop requires the minimum quantity of urea for its growth, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Urea and Its Role**: Urea is a nitrogen-rich fertilizer commonly used in agriculture to promote plant growth. It provides nitrogen, which is essential for the development of plants.

2. **Identify the Crops**: The question mentions four crops, but we need to focus on their nitrogen requirements. For this solution, we will consider groundnut and other common crops.

3. **Analyze Nitrogen Requirements**: Different crops have different nitrogen requirements. Groundnut is known for its ability to fix atmospheric nitrogen through its root nodules, which reduces its dependency on external nitrogen sources like urea.

4. **Compare Urea Requirements**: Among the crops, groundnut requires the least amount of urea due to its high nitrogen-fixing capability. In contrast, other crops typically require more urea to meet their nitrogen needs.

5. **Conclusion**: Based on the analysis, the crop that requires the minimum quantity of urea for its growth is **groundnut**.

### Final Answer:
The crop that would require minimum quantity of urea for its growth is **groundnut**.
