Nodule formation is reduced in legume roots due to the deficiency of

Options

A. chlorine
B. boron
C. sulphur
D. (2) and (3)

Answer

**Step-by-Step Solution:**

1. **Understanding Nodule Formation**: Nodule formation in legume roots is a crucial process for nitrogen fixation, where symbiotic bacteria (like Rhizobium) convert atmospheric nitrogen into a form that plants can use.

2. **Identifying Nutrient Deficiencies**: The question asks about the deficiency of specific nutrients that can reduce nodule formation. The options provided are:
- A) Chlorine
- B) Boron
- C) Sulfur
- D) Both B and C

3. **Analyzing Each Option**:
- **Chlorine**: While chlorine is an essential micronutrient, it is not directly involved in nodule formation.
- **Boron**: Boron is a micronutrient that plays a significant role in plant growth and development, including nodule formation.
- **Sulfur**: Sulfur is a secondary nutrient that is essential for the synthesis of amino acids and proteins, which are vital for the development of nodules.

4. **Conclusion**: Both boron and sulfur deficiencies can lead to reduced nodule formation in legumes. Therefore, the correct answer is option D, which includes both boron and sulfur (B and C).

5. **Final Answer**: The correct answer is option D (both B and C).
