DavidIf you are a farmer in Sri Lanka, you understand the importance of a reliable water supply for your crops. Drip irrigation systems are an effective solution to ensure your plants get the water they need while conserving water and reducing costs.
Drip irrigation systems have become increasingly popular in Sri Lanka due to their efficiency and effectiveness in delivering water directly to the plant’s roots.
In this article, we will explore the benefits, costs, and types of drip irrigation systems available in Sri Lanka, helping you make an informed decision for your farming needs.
Drip Irrigation System In Sri Lanka
If you’re looking to increase crop yields while saving water, then drip irrigation is a system you should consider using in Sri Lanka.
Drip irrigation delivers water directly to the roots of plants, using a network of tubes with small holes, known as emitters, to distribute water slowly and precisely. This system can be used for a variety of crops, including vegetables, fruits, and flowers. It also helps reduce water usage, increase crop yields, and improve soil fertility.

Types of Drip Irrigation System in Sri Lanka
There are different types of drip irrigation system in Sri Lanka and the ideal one you choose depends on the soil property, landscape, and other important factors.
Below are the common types of drip irrigation systems in Sri Lanka.
#1. Surface Drip Irrigation
Surface drip irrigation is a system that involves laying the drip tubing on the soil surface, where the water drips directly onto the soil.
This type of irrigation system is commonly used for row crops in Sri Lanka, including rice, maize, and vegetables.

The installation process of surface drip irrigation in Sri Lanka involves laying out the drip tubing along the rows of crops, with emitters spaced according to the needs of the specific crop.
The tubing can be secured with stakes or buried slightly under the soil to prevent damage.
One of the benefits of surface drip irrigation is that it helps to conserve water, as it delivers water directly to the plants’ roots without waste from evaporation or runoff.
It also allows for more precise control over the amount of water delivered to each plant, which can improve crop yield and quality.
However, it is important to note that surface drip irrigation may not be suitable for all crops in Sri Lanka, particularly those with deep root systems.

It is important that proper maintenance of the system is necessary to prevent clogging and ensure efficient water delivery.
#2. Subsurface Drip Irrigation
Subsurface drip irrigation is an efficient method of irrigation that involves placing the drip tubing below the soil surface, where water is delivered directly to the root zone of the plants.
This type of irrigation is ideal for crops with shallow roots, as it reduces water loss through evaporation and runoff.
The installation process involves laying out the drip tubing in rows and burying it at a depth of 6-12 inches below the soil surface.
The benefits of subsurface drip irrigation include improved crop yield, reduced water use, and improved soil health.
Crops suitable for subsurface drip irrigation in Sri Lanka include vegetables, fruit trees, and cotton.

#3. Inline Drip Irrigation
Inline Drip Irrigation is a highly efficient system used for providing a consistent water supply for fruit trees, vineyards, and other permanent crops.
The drip emitters are placed directly into the tubing, which is then buried beneath the soil surface. This system allows for precise water distribution, preventing wastage and reducing the risk of disease.
The installation process involves laying the tubing along the rows of trees or vines and connecting it to a water source.
Inline drip irrigation is particularly suitable for areas with limited water resources, and crops that require a regulated water supply.
#4. Micro-Sprinkler Irrigation
Micro-sprinkler irrigation system works by using small sprinklers to distribute water over a wider area. The system is installed above the ground and can cover a larger area compared to drip irrigation.
The installation process involves connecting the micro-sprinklers to a water source and laying out the tubing. The benefits of this system include water conservation and improved plant growth.
Micro-sprinkler irrigation is suitable for crops such as leafy vegetables that require frequent watering and a consistent water supply.
Best Practices of using Drip Irrigation System in Sri Lanka
- Monitor the soil moisture regularly and adjust irrigation scheduling accordingly.
- Use quality filters to prevent clogging of emitters.
- Ensure proper installation and maintenance of the system to prevent leaks and reduce water waste.
- Use high-quality drip tubing and emitters to ensure uniform water distribution.
- Practice crop rotation and soil management practices to maintain soil health and fertility.
Measures to Maintain Drip Irrigation System in Sri Lanka
- Clean the filters regularly to prevent clogging of emitters.
- Monitor the system for leaks and repair them promptly.
- Use high-quality tubing and emitters to reduce the risk of damage and wear.
- Flush the system regularly to prevent buildup of minerals and other contaminants.
- Maintain proper pressure and flow rates to ensure optimal system performance.
Tips to Select the Right Irrigation System in Sri Lanka
- Consider the water source and availability when choosing a system.
- Choose a system that is suitable for the crop type and soil conditions.
- Take into account the topography and layout of the field.
- Consider the initial cost and long-term maintenance requirements of the system.
- Consult with experts or professionals to ensure the most suitable system is chosen.
Advantages of Drip Irrigation System in Sri Lanka
- Saves water as it delivers water directly to the roots of plants.
- Reduces weed growth as water is only delivered to the plant, not the surrounding area.
- Enhances crop yield and quality by ensuring consistent water supply.
- Can be used on any terrain, even on slopes and irregularly shaped fields.
- Reduces labor costs as it requires minimal manual intervention.
Disadvantages of Drip Irrigation System in Sri Lanka
- Initial installation costs can be high.
- Requires regular maintenance to ensure optimal performance.
- Clogging of emitters and tubing can occur if not maintained properly.
- Can be affected by power outages and interruptions in water supply.
