A diagram indicates a system that delivers water directly to plant root zones using emitters close to the plants. Which irrigation system is depicted?

• A. Triangular spacing
• B. Drip System
• C. Drainage System
• D. Lighting System

Answer: (B)

Emphasize targeted, low-volume delivery to the root zone. When water is delivered directly to the area where the plant roots are, through emitters placed close to each plant, the system is designed to apply small amounts of water slowly right at the base. This is the hallmark of a drip irrigation system. It minimizes evaporation and runoff by keeping application near the root zone and reducing wetting of non-target areas.

The other options don’t describe a system that uses emitters positioned at plants. A triangular spacing concept is about how sprinklers might be arranged, not a specific irrigation method. A drainage system removes excess water, not deliver it. A lighting system provides illumination, not irrigation.

So the diagram showing emitters near plants delivering water directly to the root zones corresponds to a drip irrigation system.
