Final answer:
The common methods of irrigation in order from least efficient to most efficient are flood irrigation, sprinkler irrigation, and drip irrigation.
Step-by-step explanation:
The common methods of irrigation in order from least efficient to most efficient include:
- Flood irrigation: This method involves flooding the entire field with water. It is the least efficient method as it results in a lot of water waste due to runoff and evaporation.
- Sprinkler irrigation: This method involves spraying water over the field using sprinklers. It is more efficient than flood irrigation as it reduces evaporation, but still has the potential for some amount of water waste.
- Drip irrigation: This method involves supplying water directly to the roots of plants through a network of pipes and emitters. It is the most efficient method as it minimizes water loss due to evaporation and runoff.
