Drip Irrigation
High Efficiency Irrigation Systems (HEIS) Drip & Bubbler
In this system, water and nutrients are applied directly to the plant roots instead of the whole fields through a network of pipes. As a result, it provides proper environment, air, water and fertilizer for the growth/development of plant.
Advantages
- Saving of water up to 50%
- Good crop quality and increased production by 25 -30 %
- Enhanced water productivity
- Leaching losses of nutrients are minimized
- Proper and less use of fertilizer provides 40-50 % saving in inputs
- Precision land leveling is not necessary
- Provides water uniformly to all plants
Advantages
- Moisture content in root zone is maintained
- Soil erosion is decreased
- Reduced risk of disease
- Less use of energy as the system operates on low head
- Saving of time up to 40-50% and cost of production up to 20-30%
- Timely and easy double sowing is possible
- Less labor cost for irrigation and fertilization
Constraints
- High initial cost and maintenance requirements
- Restricted plant root development
- Salt accumulation near plants (along the edges of the wetted zone)
- Application of insoluble or slightly soluble fertilizers such as super phosphate or
- Sulphate of potash is not readily possible
- Non availability of local material
- Needs backup support Complicated/overdesigned systems
- System cost higher for small land holdings
- Farmers’ misconceptions about the system
- Flat rate of electricity in case of Balochistan
