Which of these processes should a farmer carry out in order to separate the brown-coloured outer covering of rice from the rice grains?

Options

A. Harvesting
B. Winnowing
C. Threshing
D. Fallowing

Answer

To separate the brown-colored outer covering of rice from the rice grains, a farmer should carry out the process of winnowing. Here’s the step-by-step explanation:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a method to separate the brown outer covering of rice from the grains. This outer covering is known as the husk.

2. **Identifying the Options**: The options provided are:
- Harvesting
- Winnowing
- Threshing
- Fallowing

3. **Analyzing Each Process**:
- **Harvesting**: This is the process of cutting and collecting mature crops. It does not separate the husk from the grains.
- **Winnowing**: This process involves tossing the harvested grains into the air so that the lighter husk is blown away by the wind, while the heavier rice grains fall back down. This effectively separates the husk from the grains.
- **Threshing**: In this process, the grains are beaten or rubbed to separate them from the stalks. It does not specifically target the separation of the husk from the grains.
- **Fallowing**: This is a practice of leaving the land uncultivated to regain its fertility. It does not relate to the processing of rice.

4. **Conclusion**: Among the options, winnowing is the correct process for separating the brown-colored outer covering (husk) from the rice grains.

### Final Answer:
The farmer should carry out **winnowing** to separate the brown-colored outer covering of rice from the rice grains.
