3. Introduction
What is Controlled Environment Agriculture?
 It is any agricultural technology that enables the
grower to manipulate a crop's environment to the
desired conditions.
 It is defined as a combination of engineering, plant
science, and computer managed control
technologies used to optimize plant growing
systems, plant quality, and production efficiency.

4.  Production under adverse condition of
environment.
 Increase productivity (Production/Unit area) &
Getting maximum profit.
 To grow premium quality produce using a minimum
of space, water and fertilizer.
Objectives

5. Parameter that is controlled in CEA:
• Light
• Temperature
• CO2
• Relative Humidity

6. Light
• White or reflective mulch films is use for reflect the sunlight back to
the plants
• Light levels of up to 42,000 lux for duration of 12-18 hours have been
found to be increase plant growth by Utilizing fluorescent lamps of
suitable quality.

8. Temperature
Forced-air heaters- : Commonly used in commercial greenhouse
ranges.
 Infrared radiant heaters- : The major advantage of this type of
heater is that it conserves energy and has no problems with pollutants.

9. CO2
Higher level of CO2 in greenhouses could been managed by:
• Ventilation
• Decomposition of mulches
• Solid CO2
• Liquid CO2

10. Humidity
• Control of humidity is generally possible through ventilation, heating
and misting.
• Various types of evaporative cooling systems are:
1) Fan and Pad system
2) Fan-tube ventilation system
3) Fogging and misting devices

11. There are Mainly five systems of CEA:
• Green House
• Hydroponic
• Aeroponic
• Vertical Farming
• Building Integrated Agriculture

12. Green House:
 A greenhouse is a structural building with different
types of covering materials, such as a glass or plastic
roof and frequently glass or plastic walls.

13. Hydroponic
Cultivation in
water
Hydroponic

14. Basic Hydroponic Systems:
• Active : In this system pumps and other devices
are use for deliver nutrient solutions to plant roots.
e.g.: Nutrient Film Technique (NFT)
Flood and Drain System (Ebb and Flow)
• Passive: There is no any nutrient mover system.
e.g. : capillary system

16. Aeroponic Cultivation in Air
Aeroponic

17.  Three type of Aeroponic system:
Low-Pressure Units:
A low pressure pump delivers nutrient solution via jets that drips
back into reservoir.
High-Pressure devices:
In this system , the mist is generated by high-pressure pumps,
are typically used in the cultivation of high value crops .
Commercial systems:
This systems include disease prevention, pathogen Resistance
features, precision timing and nutrient solution pressurization, Heating
and cooling sensors, thermal control of solution etc.

18. Vertical farming
cultivation of plants or
in skyscraper-like
structures,
Vertical Farming

21. Building Integrated
Agriculture
cultivation of plants
In built environment.
BIA

22. Typical characteristics of BIA installations include:
• Waste heat captured from a building's heating-ventilation-air
condition system (HVAC):
Purpose :To help maintain good indoor air quality through adequate
ventilation with filtration and provide thermal comfort.

23. Solar photovoltaic :
Is a method of generating electrical power by converting sunlight
into direct current electricity using semiconducting materials that
exhibit the photovoltaic effect.
Rainwater catchment systems:
In one tank all the rain water comes through pipes from the roof of
Building it is being stored in that tank and then used for irrigation to
plants.

24. Conclusion
These all are Latest system that improve the
productivity under controlled environment.
Result of analysis says that the crop productivity is
20% to 30% increases using these systems.
