Which of the following describes an open irrigation system?

• A. Water is recycled within the system
• B. Water is collected from rainfall
• C. Water is not recycled and drains away
• D. Water is filtered before use

Answer: (C)

An open irrigation system is characterized by the absence of water recycling; instead, it allows water to flow through the system and eventually drain away. In this type of system, water is delivered to the plants but is not reused, often leading to runoff. This setup can lead to inefficiencies, as water is not retained for future use and may contribute to water waste. In contrast, other systems such as closed or recirculating systems involve filtering, recycling, or collecting rainfall, which promotes sustainability and efficiency. An open system focuses primarily on direct supply to crops, illustrating a straightforward but less resource-efficient approach.
