Step 1: Understanding the Concept:
This question tests knowledge of planting systems, specifically the quincunx system.
Step 2: Detailed Explanation:
The quincunx system is a modification of the square system.
In this system:
- Additional plants (pollinisers or filler plants) are planted at the center of each square.
- This creates a diamond pattern.
For planting pollinisers in the quincunx system:
- The pollinisers should be placed in the middle of each square.
- In terms of positioning, it is set as Every 2nd tree in every 2nd diagonal row.
This means:
- In diagonal rows, alternate positions are occupied by pollinisers.
- This ensures uniform distribution of pollinisers.
Step 3: Final Answer:
Thus, in quincunx system, pollinisers can be set as every 2nd tree in every 2nd diagonal row, which corresponds to option (B).
