4. Background
Its approve that 50% of irrigated water is actually used
by plants and the remaining water resources are wasted.
Sprinkler irrigation system saves up to 50% of water
compared to surface irrigation method. That’s why we
interested and like to present a presentation on this
topic.

5. Introduction
Water is a key factor in increasing agricultural production,
in such case irrigation is most important factor. One such
method of modern irrigation is sprinkler irrigation system
which is becoming more and more popular among the
farmers across the developed country.

6. About Sprinkler Irrigation
 Pressurized irrigation through
devices called sprinklers
 Sprinklers are usually located
on pipes called laterals
 Water is discharged into the air and hopefully
infiltrates near where it lands
6

7. Sprinkler Irrigation System
 Spraying Water like a natural rainfall.
 Water pressure through Nozzle.
 pressure is provided by a pump.
 Selection of nozzle sizes, operating pressure and
spacing.

9. Components of Sprinkler irrigation
system
 Water source - open well / tube well / bore well /
canal etc.
 Pumping unit - centrifugal, submersible
 Sprinkler - main and lateral pipe lines, riser pipe,
sprinklers (nozzles)

10. Other accessories used in the sprinkler
system are
1. Reducers
2. Elbows
3. End plug Tees
4. Regulators and Gauges
5. Valves
6. Filters

11. Soil Suitability
Suitable for lands and on shallow soils.
best suited to coarse sandy terrain.
suitable in undulating terrain.
adopted in hilly regions.
11

12. Crops Suitability
all crops are suitable except crops like paddy,
jute, etc.
The dry crops, vegetables, flowering crops,
orchards, plantation crops like tea, coffee are all
suitable and can be irrigated through sprinklers.
12

13. General Rule For Sprinkler Irrigation
System Deign
Main Should be laid up and down hill.
Lateral should be laid across the slope or nearly on
the contour.
For multiple lateral operation, lateral pipe sizes
should be more than two diameter.
Water supply source should be nearest to the
center of the area.
13

14. General Rule For Sprinkler Irrigation
System Deign Cont.
Layout should facilitate and minimize lateral
movement during the season.
Booster pump should be considered where
small portion of field would require high
pressure at the pump.
Layout should be modified to apply different
rates and amount of water soils are greatly
different in the design area.

15. Selecting the most appropriate sprinkler
system
While selecting a sprinkler system, the most
important physical parameters to be considered
are:
1) The crop or crops to be cultivated.
2) The shape and size (acres) of the field.
3) The topography of the field.
4) The amount of time and labor to operate the
system.
15

16. Type of Sprinkler Systems
There are many types of Sprinkler systems
available in the market. On the basis
of the arrangement for spraying irrigation water,
sprinkler systems are classified
as :
i) Rotating head system
ii) Perforated Pipe system
16

17. Advantages
 Sprinkler irrigation does not require surface shaping of leveling.
 Can be applied to areas of variable topography.
 Flexibility is possible because sprinkler heads are available in a
wide range of discharge capacities.
 cost of labor is generally reduced.
 Erosion of soil can be eliminated.
 Chemical and fertilizer applications are easily used with sprinkler
systems.
 No special skills trained personal can operate the system
reasonably well.
17

18. Advantages cont.
 Frequent and light irrigation possible giving better
response from the crops.
 Increase in yield and quality, early ripening, water
conservation and alternative value of specific
period saving of labor, machinery, fertilizer and
pesticides.
 Soil moisture is maintained at optimum level by
sprinkler irrigation and 20 higher yields are
obtained of crops and the quality of other crops is
also good.

19. CONSTRAINTS IN THE APPLICATION OF
SPRINKLER IRRIGATION:
I. Uneven water distribution due to high winds.
II. Evaporation loss when opening under high temperatures.
III. Highly impermeable soils are not suitable.
IV. Initial cost is high.
V. Proper design.
VI. Lack of package of practices.
VII. Lack of awareness.
VIII. Lack of social concern to save natural resources.
IX. High water pressure required in sprinkler(>2.5kg/cm2)
X. Difficulty in irrigation during wind in sprinkler.
