Which of the following is the main objective of solution culture technique ?

Options

A. Soil less cultivation of plants
B. Identification of essential elements
C. Discovery of deficiency symptoms of essential elements
D. Both (2) & (3)

Answer

To answer the question regarding the main objective of the solution culture technique, we can break down the information provided in the video transcript into a step-by-step solution.

### Step-by-Step Solution:

1. **Understanding Solution Culture Technique**:
- The solution culture technique is also known as hydroponics. It involves the cultivation of plants without soil, using a nutrient-rich solution instead.

2. **Identifying the Main Objectives**:
- The main objectives of using the solution culture technique include:
- **Soil-less cultivation**: This is a method to grow plants without the use of soil.
- **Improving yield and quality**: Hydroponics aims to provide better yields, rapid growth, and strong plants by using a nutrient-rich solution that is well-aerated.

3. **Experimental Purpose**:
- The technique allows for the identification of essential elements required for plant growth. By adjusting the concentrations of these elements in the nutrient solution, one can observe the effects on plant growth and identify deficiency symptoms.

4. **Conclusion**:
- The main objective of the solution culture technique is to enhance plant growth and yield through controlled conditions, while also allowing for experimentation to identify essential nutrients and their effects on plant health.

5. **Final Answer**:
- Therefore, the correct options that represent the main objectives of the solution culture technique are related to improving yield and identifying essential elements.
