Hydroponics is the method of

Options

A. water conservation
B. plant development in water without soil
C. plant development without soil
D. plant development in saline soil

Answer

**Step-by-Step Text Solution:**

1. **Understanding Hydroponics**: Hydroponics is a method of growing plants without soil. Instead, it utilizes a nutrient-rich water solution to provide essential minerals and nutrients directly to the plant roots.

2. **Identifying the Correct Option**: Among the options provided:
- Water conservation
- Plant development in water without soil
- Plant development without soil
- Plant development in saline soil

The most accurate description of hydroponics is "plant development in water without soil."

3. **Clarifying Hydroponics**: Hydroponics can also be referred to as soil-less agriculture, test tube farming, tank farming, or chemical garden. These terms highlight the absence of soil and the use of controlled environments for plant growth.

4. **Commercial Application**: In commercial hydroponics, plants are often grown in large shallow tanks made of concrete, cement, or metal. These tanks are filled with a nutrient solution that is circulated using pumps to ensure that plants receive adequate nutrients.

5. **Purpose of Hydroponics**: This method is not only used for growing plants but also for research purposes to determine which mineral elements are essential for plant growth and development. It can also enhance the yield of various ornamental plants like roses and snapdragons.

6. **Conclusion**: Based on the above points, the correct answer to the question is "plant development in water without soil," which corresponds to option B.
