Precise and regulated application of irrigation water and plant nutrients at low pressure and frequent intervals through drippers/emitters directly into the root zone of plant with the help of close network of pipes is known as drip irrigation system.
Advantages
- Increase in production & productivity.
- Improves quality and ensure early maturity of the crops.
- Water Saving up to 40% – 70%.
- Controls weed growth, saving of fertilizer (30%) and labour cost (10%).
- Fertigation / Chemigation can be made efficiently.
- Control diseases.
- Use of saline water is possible.
- Soil erosion is eliminated.
- Suitable for uneven / undulating land.
- High Water Use Efficiency.
