4.  COMPANY PROFILE
• Netafim™ is an Israeli company of drip and micro-irrigation products for
agriculture, greenhouse, etc. applications.
• The company's offering includes drippers, dripper-lines, sprinklers and micro-
emitters.
• Netafim holds an over-30% share of the global drip irrigation market, and is
recognized as the world-leading provider of drippers and dripper-lines.

world-wide and employs over 4,000 workers.

6.  MICRO IRRIGATION SYSTEM
PRINCIPLES OF MICRO IRRIGATION SYSTEM
 Water is applied directly to the root zone of the plants.
 Water is applied at frequent intervals at precise quantities based on
crop water requirements.
 Water is applied through a low-pressure pipe network comprising
mains, sub mains, laterals and emitting devices.

7.  NEED OF MICRO IRRIGATION
 The population is increasing that’s way demand of food supplement should be
increased. So, the pressure on agricultural land is higher for producing more to
meet the demands of food. In such condition it needs advanced technology.
The water resources are limited and the requirement in agricultural practices,
industrial use and domestic use is increasing rapidly.

8.  Need of micro irrigation is high water use efficiency and increased yield.
Besides water saving it was also needed to get optimum crop production with
available limited resources i.e. land, water, time, power etc. to increase water
use efficiency, to maintain quality of water and land, fertilizer saving.
 It can be the most effective method of irrigation in areas which are not well
suited to surface irrigation system. It was also needed to control disease and
pests problems to reduce weed growth and can be used on alkaline or saline
soils.

9.  MAIN TYPES OF MICRO IRRIGATION
 Drip irrigation
 Sprinkler irrigation

10.  DRIP IRRIGATION SYSTEM
 What is Drip Irrigation System ?
Drip irrigation system is the method of applying uniform and precise amount of
water directly to the root zone of the plants as per the requirement, through emitters
at frequent intervals over a long period of time, via a low-pressure pipe network
comprising of mains, sub mains and laterals.

11.  BENEFITS OF DRIP IRRIGATION SYSTEM
 Saves water up to 70% compared to traditional methods of irrigation.
 Higher crop yields.
 Improved quality of harvested produce of crop.
 Increased efficiency in fertilizer use.
 Improved diseases and pest’s control.
 Improved tolerance to salinity.
 Reduced weed growth.

12.  LIMITATIONS OF DRIP IRRIGATION SYSTEM
 High capital costs.
 High power requirement.
 Emitter clogging.
 Damage chances.
 Salt accumulation.

46.  INSTALLATION OF DRIP IRRIGATION
SYSTEM
• INTRODUCTION
There are many equipment’s are required in the drip irrigation
system. Installation of Micro / Drip irrigation system can be divided
into three stages as below,
1)Installation of filter station
2)Connecting mainline and sub-mains
3)Laying of laterals with drippers / Inline system

47. 1) INSTALLATION OF FILTER STATION
• Install the sand / screen filters in the correct position on the leveled
platform.
• pressure gauge, back wash, bypass and air release valves.
• Check that the filter candles and mushrooms.

48. 2. CONNECTION OF MAIN OR SUB MAIN LINE
• PVC pipelines should be laid at a depth of minimum 2 feet below the ground
surface to avoid possible damage
• main pipeline is laid starting from the filter outlet Air relief valve and sectional
valves are provided on mainline

50. 3. CONNECTION OF LATERALS
• To connect the laterals to the sub-mains, holes are drilled on the PVC submain
pipes using appropriate drill guide and drill
• Grommets are fixed in the holes and takeoffs are fixed on the grommets.
• Laterals are then connected to the take-offs.
• extra length of lateral is provided For account for snaking effect and shrinking
allowance.

51. EMITTERS/DRIPPER FITTINGS (ONLINE
DRIP ONLY)
• To connect the emitters/dripper to the laterals, holes are drilled on the Driplines
(laterals) using appropriate drill guide and drill.

52.  Dripper placement and spacing depends on the type of soil, age of
the crop and the extent of the root zone.

53. VISION

57. CONCLUSION
• NETAFIM irrigation has huge number of products which is available in various
ranges of discharge and diameter. NETAFIM irrigation manufactured every
fitting for MIS system. It is concluded that the quality of material is very good
and response about material from farmers is also good.
• We have also concluded that the reasons for large market of NETAFIM irrigation
Systems Ltd. are that they hold campaigns and meet with the farmers, take visits
in villages for convincing farmers about MIS and their after sales service is
good.
