2.  Introduction
 What is Drip Irrigation
 Components of irrigation
 Why should I use drip irrigation
 Methods of Irrigation
 Advantages
 Disadvantages
 Conclusion

3.  Irrigation may be defined as the process of supplying
water to land by artificial means for the purpose of
cultivation.
 Ordinarily water is supplied to land by nature through
rain but generally it is not enough for the proper
growth of plants.
 As such as the basic objective of irrigation is to
supplement the natural supply of water to land so as
to obtain they an optimum yield from the crop grown
on the land.

4.  Drip irrigation, is also known as trickle irrigation or micro
irrigation or localized irrigation, is an irrigation method that
saves water and fertilizer by allowing water to drip slowly to
the roots of plants, either onto the soil surface or directly onto
the root zone, through a network of valves, pipes, tubing, and
emitters.

5.  Pumping set
 Filters
 Mainlines
 Sub-main lines
 Laterals
 Emitters

6. Pumping set:
To create a pressure
about 2.5 Kg/sq cm to
regulate the amount of
water to be supplied.
•Filter :
To filter the water in Order
to remove the suspended
impurities from water.

7. Main lines:
It is a Distribution system in drip irrigation. Rigid
PVC and high density polyethylene pipes are used as
main pipes to minimized corrosion and clogging.
Pipes of 65 mm diameter and with pressure rating of 4
to 10 kg/sq. cm
Sub Main lines:
It is usually connected to the main lines through a
control valve assembly.

8. Emitters
These connect to the tubing or can be inside the tubing
and deliver water at a slow, consistent rate, usually,
0.5, 1, 2 gallons per hour.

9.  Drip irrigation saves water because little is lost to
runoff or evaporation.
 This watering method also promotes healthy plant
growth, controls weed growth, and reduces pest
problems.

10.  Surface Irrigation Methods: The water is applied by
spreading in it sheets or small streams on the land to be
irrigated.

11. Sub-Surface Irrigation Methods: The water is applied
below the ground surface so that it is supplied directly to the
root zone of the plants.

12. Sprinkler Irrigation Methods:
The irrigation water is applied to the land in the form
of spray, somewhat as in ordinary rain.

13. Drip irrigation is useful for crop
Fruit crops :
Banana, Grapes, Citrus, Pomegranate ,Papaya, Pineapple,
Watermelon, Sweet lime, Mango.
Vegetable crops :
Cabbage, Cauliflower, Okra, Tomato, Potato, Onion, Chillis,
Radish, Brinjal, French been, Capsicum, Bhindi, Beans,
Carrots, Cucumber, Bottle gourd, Gherkins.
Commercial crops :
Sugarcane, Cotton, Ground nut.

14.  Reduced water use
 Reduced pest problems
 Simplicity
 Low pumping needs
 Automation
 Adaptation
 Production advantages
 Weed control
 High yield
 Joint management of irrigation

15.  Drip irrigation requires an economic Investment
 Drip irrigation requires maintenance and high-quality
water
 Water-application pattern must match planting pattern
 Shallow root depth.
 Safety
 Leak repair

16.  Drip irrigation is a latest sub-surface method of
irrigating water with higher water demands in arid
region.
 It may not be applicable to all farms.
 Drip irrigation increase yields.
