Which of the following planting systems is generally followed on the hills for the establishment of a fruit orchard?

• A. Square system
• B. Rectangular system
• C. Hexagonal system
• D. Contour system

Hint:

Contour planting reduces soil erosion and increases water infiltration, making it ideal for hilly regions.

Answer 1

The Correct Option is D

Step 1: Planting systems overview.
Planting systems are chosen based on topography, slope, and soil conditions.

Step 2: Hillside planting.
On hilly terrains, planting across the slope (contour planting) is followed to reduce soil erosion and conserve moisture.

Step 3: Elimination of other systems.
- Square and rectangular systems are suitable for plain lands. - Hexagonal system is also practiced on plains for maximum utilization of land. - Only the contour system is suitable for hills.

Step 4: Conclusion.
Hence, on hills, the contour system is adopted.

Final Answer: \[ \boxed{\text{Fruit orchards on hills are planted using the Contour system.}} \]
