IN
VEGETABLE CROPS

2. INTRODUCTION:-
• Hydroponics is a technology for growing plants in nutrient
solutions (water containing fertilizers) with or without the use of
an artificial medium (sand, gravel, vermiculite, rockwool, perlite,
peatmoss. coir, or sawdust) to provide mechanical support.
• A plant gets its food source by turning Co2, light and water (or
hydrogen) into carbo-hydrates through a process called
photosynthesis. With hydroponics growing, plants are grown
without soil so they must get their nutrients from the nutrient
solutions added to water.

3. WHICH CROPS CAN BE GROWN IN
HYDROPONICS?
• Basically all high value crops can be grown. Popular are tomatoes,
cucumbers and peppers in drain to waste systems and lettuce and
herbs in gravel flow systems.

4. TAKING CARE OF PLANTS:-
• Different crops are planted at different spacing. Small-growing
plants can be planted close to each other. Large-growing plants
need more space to grow and must be spaced further apart.
• Water flow must be checked every day and adjusted when
necessary.
• If plants turn yellow, it is normally a symptom of nutrient
deficiency, too little light or a disease.
• Inspect the leaves every day for disease symptoms and insects.
Act immediately if a problem occurs.
• Tall plants need to be trained and pruned to make optimal use of
the expensive greenhouse space.

5. HYDROPONIC SYSTEMS:-
• WICK SYSTEM:-
The Wick system is by far the
simplest type of hydroponic
system. This is a passive
system, which means there
are no moving parts.
• WATER CULTURE:-
The water culture system is the
simplest of all active hydroponic
systems. The platform that holds
the plants is usually made of
Styrofoam and floats directly on the
nutrient solution.

6. • NUTRIENT FILM TECHNIQUE:-This
is the kind of hydroponic system most
people think of when they think about
hydroponics. N.F.T. systems have a
constant flow of nutrient solution so no
timer required for the submersible pump.
• AEROPONIC :-The aeroponic system
is probably the most high-tech type of
hydroponic gardening. Like the N.F.T.
system above the growing medium is
primarily air.
• DRIP SYSTEM :-Drip systems are
probably the most widely used type of
hydroponic system in the world. Operation
is simple; a timer controls a submersed
pump.

7. DIFFERENCES BETWEEN HYDROPONIC
VEGETABLE PRODUCTION AND SOIL
PRODUCTION :-
S.No Hydroponic Field production
1. No soil is required Good topsoil is required
2. Plants are irrigated automatically Plants need to be irrigated to minimize water
stress
3. Nutrients are available at all times
Only soluble fertilizers are used.
Nutrients must be added to soil.
4. Soil borne diseases can be eliminated Soil borne diseases can build up in the soil.
5. Hydroponic production is not organic
because artificial nutrients are always
used and plants are usually not grown
in soil.
It is possible to produce organic vegetables
in soil because one can use organic fertilizers
such as compost and manure.

8. HYDROPONIC TOMATO:-

9. SOIL VS. HYDROPONICS PLANT :-

10. HYDROPONICS CUCUMBER :-

11. HYDROPONICS LETTUCE :-

12. ADVANTAGES OF HYDROPONICS :-
• No soil is needed
• The water stays in the system and can be reused- thus, lower water costs
• It is possible to control the nutrition levels in their entirety- thus, lower
nutrition costs
• No nutrition pollution is released into the environment because of the
controlled system
• Stable and high yields
• Pests and diseases are easier to get rid of than in soil because of the
container’s mobility

13. DISADVANTAGES OF HYDROPONICS :-
• The hydroponic conditions (presence of fertilizer and high humidity) create
an environment that stimulates salmonella growth.
• Another disadvantage is pathogens attacks including damp-off due to wilt
caused by the high moisture levels associated with hydroponics and overwa-
tering of soil based plants.
• Also, many hydroponic plants require different fertilizers and containment
system.
