Question

Planting geometry that ensures a uniform incidence of solar radiation is:

• A. Square planting
• B. Rectangular planting
• C. Mixed planting
• D. Random planting

Hint:

Think about which spacing pattern keeps row distance and plant distance equal in every direction.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Planting geometry decides how much sunlight each plant intercepts and how evenly that light spreads across the field. The pattern of spacing between and within rows controls the shape of the area each plant occupies.

Step 2: Key Formula or Approach:
In square planting the row to row distance equals the plant to plant distance, so every plant gets an identical, symmetric patch of ground around it. This symmetry means the canopy develops evenly in every direction and no plant shades its neighbour more from one side than another.

Step 3: Detailed Explanation:
In rectangular planting the row spacing is wider than the plant spacing within the row, so plants along the row compete and shade each other sooner than plants across the row. This gives an uneven, direction dependent light pattern, not a uniform one.
Mixed planting combines two or more crops in the same field, so the taller crop always throws shade over the shorter one from a fixed direction, and random planting has no fixed geometry at all, so overlap and shading vary unpredictably from plant to plant.
Only square planting keeps the plant to plant distance the same in every direction, which is what gives a uniform incidence of solar radiation over the crop canopy.

Step 4: Final Answer:
The planting geometry that gives uniform solar radiation incidence is square planting.
