4. Definition of Irrigation
 Irrigation is the artificial application
of water to plant in the correct amounts for
their growth and development .

5. Definition of Irrigation Scheduling
 Irrigation scheduling is the
process used by irrigation system
managers to determine the correct
frequency and duration of watering to
the crops.

6. Why Irrigation Scheduling necessary ?
Irrigation scheduling are necessary for
all crops because crops want proper
irrigation for there growth and
development .
If we do not provide a proper irrigation
to crops , the crops have to suffer from
many diseases, nutrients deficiency ,lack of
flowering and fruiting ,and by this result
they reduce there quality , production and
productivity.

7. Important things about Maize crop
 Common Name: Makka
 English Name: Maize/Corn
 Family: Poaceae
 Botanical Name: Zea mays
 Native: America( It was introduced into India by the Portuguese during the
seventeenth century .
 Plant Part Use: Grains, ( stem also for feeding to animals)
 Chromosome No. 2n=20
 Uses: Human food, animal feed and poultry feed, as well as for industrial
processing .
 Area and Distribution: India ranks fifth in Maize production(Ist USA). And
in India (UP is first about 15.0% of total production.
 Climate and soil: Maize can be grown in tropical subtropical and temperate
climate . It can also be grown in all types of soil ranging from sandy to
heavy clay.( Deep heavy soils are considered more suitable).

8. Criteria for Irrigation Scheduling for
Maize crop
 Regulate irrigation according to the following
growth phase of the crop(in days)
 Early vegetative growth & establishment phase: 1 to 14
Vegetative phase: 15 to 39
 Tasselling, silking phase 40 to 65
Maturity/ dough phase: 66 to 95
 Critical stage : Tasselling and silking stage

10. Irrigation of Maize
 Maize is mainly a rained kharif crop .Maize can be
grown in the rained region where distribution of rainfall
is sufficient
 It requires 50-100 cm of rainfall and it cannot be
grown in areas of more than 100 cm rainfall.
 In areas of lesser rainfall, the crop is irrigated, Long dry
spell during the rainy season is harmful for maize, Cool
and dry weather helps in ripening of the grain .
 Note – Maize required well drained soil .

3. Soil Moisture Content
4. Crop Stress
5. Soil Water Balance

13. Irrigation method in Maize
 We know that maize is rained crops so not
required of irrigation to crop but in the case of
absent rainfall we have to irrigate to maize in
different ways , that’s are following:
 Open flood method
 Border method
 Sprinkler method
 Drip irrigation method

15. Effect of improper Irrigation Scheduling on Maize crop

16. Conclusion
 Proper water management on irrigated Maize can produce
economic yields, conserve water supplies and preserve or
enhance water quality.
 No harmful effect on plant by irrigation water.
 Improvement of Net Irrigation Requirement of crop
 In hence timely scheduled irrigation maize crop/other crops
give good quality and productivity.
 Fully use of nutrients
 Less chances from disease attack
 Less chances stress or moisture stress condition .
 Good germination of seed
 Increase in green fodder and dry matter
 Less loss of irrigation water
