3.  Water is most essential requisite to sustain life for
plants, animals and humans.
 Approximately 70 per cent of global freshwater
consumption is used in the agricultural sector, yet
water use efficiency in many countries is below 50
per cent. (Source: International atomic energy agency)
 Water is used for carrier of nutrient from the soil to
green plant tissues. Water forms 90% of the plant
body by fresh weight basis.
 India is endowed with vast water resources which are
not distributed uniformly.
INTRODUCTION

4.  PMKSY is a Centrally Sponsored Scheme (Core Scheme)
 launched in 2015.
Pradhan Mantri Krishi Sinchayee Yojana
Its objectives are:-
 To expand the cultivable area under assured irrigation
(Har Khet ko pani).
 To improve on-farm water use efficiency to reduce
wastage of water.
 To enhance the adoption of precision-irrigation and
other water saving technologies (More crop per drop).
 To enhance recharge of aquifers and introduce
sustainable water conservation practices.

5. WATER MANAGEMENT
 Water management refers to artificial ways and
means to provide a specific quantity of water at
an appropriate time to the effective root zone of
crops deriving maximum water for higher
application efficiency and water use efficiency
(WUE).
 Water management is the activity of planning,
developing, distribution and managing the
optimum use of water.

6. TERMINOLOGIES
• INFILTRATION
• PERCOLATION
• LEACHING
• SEEPAGE
• WATER USE EFFICIENCY (WUE)
• EVAPOTRANSPIRATION (ET)

8.  The soil-plant-
atmosphere
continuum (SPAC) is
the pathway for
water moving from
soil through plants to
the atmosphere.

9. Irrigation scheduling is defined as frequency
with which water is to be applied based on needs of the
crop and nature of the soil.
Irrigation Scheduling Criteria
1. Soil water regime - Soil Moisture Tension
2. Climatological - IW/CPE Ratio
3. Plant indices - Critical Growth Stages
IRRIGATION SCHEDULING

10. A) Direct Methods:-
1. Gravimetric Method
3. Rapid Moisture Method
Tools for Monitoring Soil Moisture
B) Indirect Methods:-
1. Neutron Moisture Meter
2. Electrical resistance blocks
3.Tensiometers

11. Water requirment of crops is the amount of water
this is required to meet the evapotranspiration
rate that crop may thrive.
Where
V = Volume of water required by plant(l/day)
Ec = Pan evaporation (mm/day)
Kc = Crop factor/crop cofficient
Wp= wetted area
Sp = Spacing of crop(m2)
V = Ec×Kc×Kp×Wp×Sp
CROP WATER REQUIRMENT (Daily)

12. Water requirement of some fruit Crops
Crop Water Requirement(mm)
Banana 1200-2200
Citrus 900-1200
Grapes 500-1200
Pineapple 700-1000
Coconut 80-100 (lit/plant/day)

13. 1.Traditional Method
• Flood system, basin, Furrow method etc.
2.Modern Method/Micro irrigation
• Drip irrigation
• Sprinkler irrigation
It is defined as the artificial supply of water to
support plant growth and production in absence of
adequate supply of water through rainfall is known as
irrigation.
System of irrigation:-
IRRIGATION

14.  Check-Basin Method:-
In this method, the entire
field is divided into a number
of almost levelled plots
surrounded by levees.
TRADITIONAL METHODS
Ring Basin Method:-
In this method, a circular ring
in the periphery is prepared
to irrigate the plants.
Pitcher Irrigation:
This system is very suitable
for those areas where water
scarcity exists.

15. MODERN/MICRO-
IRRIGATION
Micro-irrigation, is the slow
application of continuous drips,
tiny streams or miniature sprays
of water above or below the soil
surface.
Micro irrigation system is
effective in saving water and
increasing water use efficiency as
compared to the conventional
surface irrigation method.

16. PRINCIPLES OF MICRO-IRRIGATION
 Water is applied directly to the root zone of the
plants.
 Water is applied at frequent intervals at precise
quantities
 Water is applied through a low-pressure pipe
network comprising Mains, Sub mains, Laterals and
Emitting Devices

17. 1. SPRINKLER IRRIGATION
 The water is applied with pressure to the surface of
any crop or soil in the form of a thin spray,
somewhat resembling rainfall.
 It discharges rate at 1000 L/h at 2.5-4.5 kg/cm².
 Suitable for undulating topography
 The rate of spray can be regulated

19. Merits Of Sprinkler
 Highly suitable for sandy, shallow and steep soils.
 25-50 percent saving in irrigation water.
 Prevent the frost damage.
 More uniform water application than surface
irrigation.
 Water use efficiency can be as high as 60%.
 Protect crops against high temperatures.

20.  High winds cause improper distribution of water.
 Evaporation losses are high especially under high
temperature and low relative humidity conditions.
 High initial investment.
 Higher energy is required for operating the
sprinkler system.
Demerits Of Sprinkler

21. 2. DRIP IRRIGATION
 Drip irrigation is defined as the
method in which the rate of
water application at very low
pressure i.e., drop by drop.
 Efficient method of providing
irrigation water directly into the
soil or at root zone of plants.
 It discharges water at 1-8 L/h at
1.5 -2.5 kg/cm²

22. Layout Of Drip Irrigation System

23. Merits Of Drip System
 50-70 per cent water saving
 40-60 per cent savings in fertilizer and chemicals
 Less evaporation losses of water as compared to
surface irrigation.
 Most suitable for widely spaced crop, orchard
trees and in green houses.
 Fertigation and herbigation also possible to apply
with drip

24. Demerits Of Drip System
 Expensive:
 Waste:
 Clogging:
 Drip tape causes extra cleanup costs after harvest.

25. The Indian Agricultural Research Institute, New Delhi has
developed an absorbent polymer called "Pusa Hydrogel" to
meet the requirements of water productivity in Agriculture.
PUSA HYDROGEL
Salient features of Pusa Hydrogel:-
 Natural polymer backbone based water absorber based on cross-
linked Potassium polyacrylate polymer
 Exhibits maximum absorbency at temperatures(40-500C)
characteristic of semi-arid and arid soils.
 Absorbs water 400 times its dry weight and gradually releases the
same.
 Low rates of soil application – 1-2 kg / ha for nursery horticultural
crops; 2.5-5 kg/ ha for field crops
 Improves physical properties of soils and the soil less media
 Helps plants withstand prolonged moisture stress
