Bacterization, deals with

Options

A. The culturing of bacteria on suitable nutrient media
B. The seed dressing with nitrogen fixing bacteria
C. The seed treatment with biopesticides
D. The control of endo-pathogenic bacteria of plants

Answer

**Step-by-Step Solution:**

1. **Understanding Bacterization**: Bacterization is defined as the process of treating seeds with specific bacteria. This technique is primarily used to enhance plant growth and improve soil fertility.

2. **Identifying the Purpose of Bacterization**: The main goal of bacterization is to introduce beneficial bacteria to the root region of plants. These bacteria can help in nitrogen fixation, which is crucial for plant growth.

3. **Examples of Bacteria Used in Bacterization**: Common bacteria used in this process include:
- **Azotobacter**: A free-living nitrogen-fixing bacterium.
- **Bacillus**: A genus of bacteria that can promote plant growth.
- **Rhizobium**: A symbiotic nitrogen-fixing bacterium that forms nodules on the roots of legumes.

4. **Analyzing the Options**: The question provides four options regarding what bacterization deals with:
- Culturing of bacteria on suitable nutrient media
- Seed dressing with nitrogen-fixing bacteria
- Seed treatment with biopesticides
- Control of endopathogenic bacteria of plants

5. **Selecting the Correct Option**: Based on the definition and purpose of bacterization, the correct answer is:
- **Seed dressing with nitrogen-fixing bacteria**. This option aligns with the primary function of bacterization, which is to enhance plant growth by introducing beneficial nitrogen-fixing bacteria.

6. **Conclusion**: Therefore, the answer to the question "Bacterization deals with" is the second option: **Seed dressing with nitrogen-fixing bacteria**.
