Question

The technique of growing plants without soil by supplying nutrients through a mist of nutrient solution is called

• A. Phytotronics
• B. Aeroponics
• C. Hydroponics
• D. Aerosols

Hint:

Soilless cultivation techniques:
- Hydroponics: Roots in nutrient solution.
- Aeroponics: Roots in air with nutrient mist.
- Aquaponics: Combining fish farming with hydroponics.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of soilless cultivation techniques.

Step 2: Detailed Explanation:
Aeroponics is a technique where plant roots are suspended in the air and misted with a nutrient solution.
Hydroponics (C) involves growing plants in a nutrient solution without soil.
Phytotronics (A) refers to controlled environment facilities for plant research.
Aerosols (D) are not a plant-growing technique.
Thus, the correct answer is aeroponics.

Step 3: Final Answer:
Thus, the technique of growing plants with a nutrient mist is aeroponics, which corresponds to option (B).
