Which one of the following crop plants is very efficent converter of solar energy and whose net productivity value ranges from 2 kg to 4 kg/`m^(2)` or even higher?

Options

A. Sugarcane and maize
B. Rice and wheat
C. Wheat and Potato
D. Bajra and Barley

Answer

To determine which crop plant is a very efficient converter of solar energy with a net productivity value ranging from 2 kg to 4 kg/m² or even higher, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Plants**:
- There are two main types of plants based on their photosynthetic pathways: C3 plants and C4 plants.
- C3 plants include crops like wheat and rice, while C4 plants include crops like sugarcane, maize, and sorghum.

2. **Evaluate Photosynthetic Efficiency**:
- C4 plants are known to be more efficient in converting solar energy into biomass compared to C3 plants.
- This efficiency is due to their unique photosynthetic mechanism, which allows them to capture and utilize sunlight more effectively, especially in high light and temperature conditions.

3. **Check Net Productivity Values**:
- The net productivity of C4 plants can range from 2 kg to 4 kg/m² or even higher, making them some of the most productive crops in terms of biomass yield.
- For example, sugarcane and maize are both recognized for their high net productivity.

4. **Identify the Correct Crop Plant**:
- Based on the information, both sugarcane and maize are excellent examples of C4 plants that fit the criteria of being efficient converters of solar energy with high net productivity.

5. **Conclusion**:
- Therefore, the answer to the question is that both **sugarcane and maize** are very efficient converters of solar energy with a net productivity value ranging from 2 kg to 4 kg/m² or even higher.

### Final Answer:
**Sugarcane and Maize**
