3. WHAT IS MICROIRRIGATION SYSTEM?
-Micro-irrigation refers to low-pressure irrigation
systems that spray, mist, sprinkle or drip.
-The term micro irrigation describes a family of
irrigation systems that apply water through small
devices.
-These devices deliver water onto the soil
surface very near the plant or below the soil surface
directly into the plant root zone.
- It is also known as pressurized irrigation system.

4. NEED OF MICROIRRIGATION SYSTEM
- Reduce the salinity of soil.
- to get timeless work.
-To reduce the evaporation and infiltration.
-To give sufficient amount of water to make a favorable
condition of soil for building up the plant tissue.
- to get higher production to compete the increasing
population of our country.
- insufficient rainfall, uneven distribution of rainfall.

5. ADVANTAGES OF MICROIRRIGATION
SYSTEM
• Water saving or water efficiency :- By applying water
only where and when it is needed, with less runoff and
less evaporation from leaves and soil, the uniform
application of water from drip irrigation systems can
achieve high water savings.
• Weed and disease reduction: - Because of limited wetted
area from non-spray type of micro-irrigation, weed
growth is inhibited and disease incidences reduced.

6. • Improved Yield: - Slow and regular application of water
and nutrients uniformly to all plants improves product
quality and uniformity, and increases yield.
• Fertilizer Saving: - Fertilizer losses are minimized,
reducing fertilizer costs.
• Labor Saving: - Less labor is required for irrigation,
weeding, and fertilizer application compared to traditional
production methods.
• Reduced Cultivation Cost: - Slow and regular application
of water keeps an optimum soil-water-air ratio in the soil
which is essential for healthy plant growth. It also reduces
the need for frequent inter-culturing, weeding, etc.
• Evaporation and soil erosion are decreased.

7. DISADVANTAGES OF MICRO IRRIGATION
SYSTEM
• High initial cost.
• Requires some management and maintenance.
• Clogging emitter and sprinkler nozzle.
• Salt accumulation near the root zone.
• Seed germination.
• Moisture restricted root zone.
• High skills are required.
• Short life time due to sun.
• Wind drift.
• A stable water supply is needed.

8. TYPES OF MICRO IRRIGATION SYSTEM
• Drip irrigation system.
• Sprinkler irrigation system.
• Fogging irrigation system.
• Bubbler irrigation system.

9. DRIP IRRIGATION SYSTEM
• Drip irrigation system: -
- It is an artificial application of water to the soil,
near the root zone of plant at frequently and slowly using
emitter.

10. CROP GROWN UNDER DRIP IRRIGATION
SYSTEM
Following crops can be successfully grown under drip irrigation
system.
• Orchard crops – grapes, banana, guava, orange, mango.
• vegetables – tomato, chilly, capsicum, cabbage.
• Cash crops – cotton, turmeric, strawberry.
• Flowers – roses, jasmine, tulip, mogra.
• Oil seed – ground nut, coconut, sunflower.
• Forest trees – teakwood, bamboo, casurina.

12. SPRINKLER IRRIGATION SYSTEM
• Sprinkler irrigation system: -
- It is a method of applying irrigation
water above the soil surface in the form of spray
or droplets, similar to the natural rain fall.

13. BASIC DATA REQUIRED FOR SPRINKLER
SYSTEM DESIGN
• Survey map of area.
• Water resource.
• Soil type.
• Climatic records.
• Type of crop.
• Hydrologic property of soil.
• Source of energy.
• Wind speed and direction.
• Water quality.

15. FOGGING OR MISTING SYSTEM
• It is the application of water in the form of very fine
spray in order to create humidity in the air at low level or
over head.
• There system are generally used in greenhouses to
control the humidity and temperature.
• The flow rate of this system is 10 to 30 l/h and with
pressure of 3.5 to 10 kg/cm2.
