Rhizobium inoculants are applied to the seeds with

Options

A. Sodium alginate
B. Mercuric chloride
C. Gum or carboxy methyl cellulose
D. 2, 4, 5 - T

Answer

To solve the question "Rhizobium inoculants are applied to the seeds with," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Rhizobium**:
- Rhizobium is a group of bacteria that form a symbiotic relationship with legumes. They are essential for nitrogen fixation, which means they convert atmospheric nitrogen into a form that plants can use.

2. **Purpose of Inoculation**:
- Inoculation refers to the process of introducing these beneficial bacteria to the seeds before planting. This enhances the nitrogen content in the soil, improving soil fertility and crop productivity.

3. **Identifying the Correct Substance for Inoculation**:
- The question asks with what substance Rhizobium inoculants are applied to the seeds. The options provided are sodium, alginate, mercuric chloride, gum, or carboxymethyl cellulose, and 2, 4, 5-T.

4. **Evaluating the Options**:
- Sodium: Not typically used for this purpose.
- Alginate: While it can be used in some applications, it is not the most common for Rhizobium.
- Mercuric chloride: This is a toxic substance and not used for inoculation.
- Gum or Carboxymethyl Cellulose: These are substances that can help in adhering the Rhizobium to the seeds, making them the most suitable option.
- 2, 4, 5-T: This is a herbicide and not relevant for inoculation.

5. **Conclusion**:
- Based on the evaluation, the correct answer is that Rhizobium inoculants are applied to the seeds with gum or carboxymethyl cellulose.

### Final Answer:
Rhizobium inoculants are applied to the seeds with gum or carboxymethyl cellulose.
