- Drip irrigation can be defined as the method in which water drips slowly via a pipe system to the roots of the plants either from above or below the soil surface.
- It is also known as micro-irrigation by which both water and soil nutrients can be saved.
- A set up of valves, tubes, pipes, and emitters is used for drip irrigation.
- The best part about drip irrigation is that valves and pumps can be operated both manually and automatically with the help of a controller.
- Drip irrigation is suitable for most soils. On clay soils water must be applied slowly to avoid surface water ponding and runoff. On sandy soils higher emitter discharge rates will be needed to ensure adequate lateral wetting of the soil.

Which of the statements given above is/are incorrect regarding the dri...
Drip irrigation is a method of watering plants where water is delivered directly to the roots in a slow and controlled manner. It is an efficient way of providing water to plants, as it minimizes water wastage and ensures that water is delivered directly to where it is needed. However, there are some incorrect statements given regarding drip irrigation.
Incorrect Statement:
d) On clay soils water must be applied speedily to avoid surface water ponding.
Explanation:
This statement is incorrect because on clay soils, water should not be applied speedily to avoid surface water ponding. Clay soils have a high water holding capacity, which means they can retain moisture for a longer period of time. If water is applied speedily, it can result in surface water ponding, which can lead to water runoff and soil erosion. Instead, water should be applied slowly and in small amounts to allow the clay soil to absorb the water gradually. This helps to prevent surface water ponding and ensures that the water is effectively utilized by the plants.
Correct Statements:
a) Drip irrigation can be defined as the method in which water drips slowly via a pipe system to the roots of the plants either from above or below the soil surface.
b) It is also known as micro-irrigation by which both water and soil nutrients can be saved.
c) The best part about drip irrigation is that valves and pumps can be operated both manually and automatically with the help of a controller.
Explanation:
a) Drip irrigation involves the use of a pipe system where water drips slowly to the roots of the plants either from above or below the soil surface. This method ensures that water is delivered directly to the roots, minimizing water loss due to evaporation or runoff.
b) Drip irrigation is also known as micro-irrigation because it delivers water in small and precise amounts, allowing for efficient use of water and nutrients. This method helps to minimize water and nutrient wastage, as water is delivered directly to the root zone where it is needed by the plants.
c) One of the advantages of drip irrigation is that it can be operated manually or automatically with the help of a controller. Valves and pumps can be used to control the flow of water, allowing for precise control of the irrigation system. This flexibility allows for convenient operation and management of the irrigation system.
In conclusion, the incorrect statement is d) On clay soils water must be applied speedily to avoid surface water ponding. On clay soils, water should be applied slowly to prevent surface water ponding and ensure efficient water utilization by the plants.
