Sprinkler Irrigation
In this method of irrigation, water is delivered through a network of pipes and pumps.
Water is available in form of the spray.
It also reduces seepage losses and other losses.
Hence, the Sprinkler method of irrigation has a higher water application efficiency.
Drip Irrigation:
This method is also called Trickling irrigation.
In this method of irrigation water is directly applied to the root zone of the plant using the drip nozzle.
Evaporation and percolation losses are considerably reduced in this method.
Hence, the duty of drip irrigation is very high.

Explanation:
Irrigation methods are used to provide water to crops in agriculture. The efficiency of an irrigation method is determined by how much of the water supplied is actually used by the crops. The statement given in the question compares the water application efficiency and duty of two irrigation methods - sprinkler and drip.
Sprinkler method of irrigation:
- In sprinkler irrigation, water is sprayed over the crop like rain.
- The water is distributed through pipes and sprinkler heads that rotate and spray water on the crop.
- This method is suitable for crops that require frequent watering and can tolerate wet foliage.
- The water application efficiency of sprinkler irrigation is high because the water is sprayed directly over the crop and there is less water loss due to evaporation or runoff.
Drip irrigation:
- In drip irrigation, water is supplied directly to the roots of the crop through small tubes or pipes.
- The water is delivered at a slow rate, drop by drop, which reduces water loss due to evaporation or runoff.
- This method is suitable for crops that require less frequent watering and cannot tolerate wet foliage.
- The duty of drip irrigation is high because the losses are least in this irrigation system. Duty refers to the amount of water that needs to be supplied to the crop per unit area.
Therefore, both statements in the given question are correct. Sprinkler method of irrigation has a higher water application efficiency, while the duty of drip irrigation is very high due to losses being the least in this irrigation system.
