3. WHAT IS WATER?
Water is extremely essential for all forms
of life. Though 70% of the earth is covered
with water, not all the water is suitable for
drinking and especially in Agriculture.
Rain water is the purest form of water.
WATER IN AGRICULTURE
4. Rivers and lakes are the main source of
fresh water.
Oceans and sea water are salty, so we
required is fresh water.
Earth, air, fire, and water were
considered by the ancient philosopher to be
the four elements.
5. Refers to farming entirely dependent on
rain conditions and without secure irrigation
facilities.
Dry farming uses special agricultural
techniques for the non-irrigated cultivation
of crops and is used Low rainfall areas
around the world.
DRYLAND AGRICULTURE
6. Dry farming is dependent on natural
rainfall and is used by farmers to
continually adopt to the presence or lack
of moisture in a given crop cycle.
14. DRYLAND AGRICULTURE
DRY FARMING
Cultivation of plants in areas with less than 750 mm of
rainfall per year.
DRYLAND FARMING
Cultivation of crops in areas with rainfall exceeding 750
mm per year.
RAIN RED FARMING
Cultivation of crops in regions with rainfall above 1,150 mm
per year.
26. Human uses the water in:
AGRICULTURE
The most important for the
agriculture is for irrigation.
FOR DRINKING
Because the body need 75% of water
to do exercise.
27. WASHING
Washing is also an important component
of several aspects of personal body hygiene.
FIRE EXTINCTION
One of the important use of the water is
fire extinction.
31. POSITIVE EFFECT
Irrigation enables greater agricultural
production than is achieved with rainfed
agriculture.
The additional food production
obtained with irrigation is essential for food
security on a global level, and on a national
level for some countries.
32. NEGATIVE EFFECT
Agricultural practices may also have negative
impacts on water quality.
Improper agricultural methods may elevate
concentrations of nutrients, fecal coliforms, and
sediment loads.
Increased nutrient loading from animal waste
can lead to eutrophication of water bodies which
may eventually damage aquatic ecosystems.
33. Effect of water on growth and yield of
different agricultural commodities
34. Water aids a plant by delivering essential
nutrients throughout it.
The plant takes nutrients from the earth
and uses them.
The plant will droop if there isn't enough
water in the cells, thus water helps it stay
straight.
35. The water in the plant transports
dissolved sugar and other nutrients.
Water scarcity prevents the plant from
receiving the essential nutrients it requires.
36. As a result, water shortage and
surplus on fields can have an equal
impact on total crop growth and
development, as well as yield and
quality.
38. When agricultural water is used effectively
and safely, production and crop yield are
positively affected.
A decrease in applied water can cause
production and yield to decrease.
39. Management strategies are the most
important way to improve agricultural
water use and maintain optimal
production and yield.
