2. INTRODUCTION
About the Flower
Scientific Name : Gerbera jamesonii
Family :Asteraceae
Also known as Transvaal daisy or Barbertondaisy
Orient : South Africa and Asiatic region and inhabits in
thetemperate mountain region (Karki, 2004).
Gerbera is the fifth most used cut flower in the world
Important varieties :
General gerbera – Red Gem, Classic Beauty etc.
Black centered gerbera – Sunspot, Faith etc.
Export varieties – Sonata, Pink Forest etc.

3. GREENHOUSE TECHNOLOGY?
A greenhouse (also called a glasshouse) is a
building or complex in which plants are
grown
Growth and healthy production of
plants under controlled favorable
conditions in closed or partially closed
space is called greenhouse
Types – Glass House, Shade Net,
Poly House

4. Importance of Greenhouse technology
Best way of utilizing the potential ofGerbera
Efficieny utilization of chemicals &fertilizers
Water requirement is limited & easy to control
Yield may be 10 – 12 times higher under suitable
conditions
Export orientedview
Major beneficiary to small holdingfarmer

5. Site-selection for green house:
1. The site should be free from pollution
2. Water should be available regularly
3. Supply of electricity should be regular
4. Soil should be properly levelled and drained
5. Poly house should be near to road side, proper approachable road must
be there to go to poly house
6. Some space should be there nearby for further extension
7. Expertise and labors should be available when required
8.Poly house should have light from all sides and wind current should not
damage the poly house. To overcome these problems, Poly house should be
preferably South-North in direction .

6. General Practices
Ploughing
General disinfection of soil by
covering the soil with plastic for
6 – 8 weeks(Solanization)

7. Bed preparation as recommended by Kumar Florist (2007)/ K.F.
biotech

8. Planting
Planting medium should be adequately porous and
well-drained.
Two –row or 4-row planting systems are generally
used.
Planting can be done round-the-year but preferably
during September-October.
The plants should be left undisturbed for 2 years for
flower production (no separation of clumps).
Treating plants with GA3(100 ppm) results in early
flowering having long stems.
Bed preparation

11. Gerbera propagation
Properties
Propagation:
Division: – Propagation through division of clumps is the most
common method.
Disease and pest free plants
4 – 5 leaves per plant at planting time
Precaution:
Crown should be 1 – 2 cm above soil

12. Harvesting
Gerbera flowers are harvested
when outer two whorls of disc
florets are perpendicular to the
stalks.
Harvested with the help of s
h
a
r
p
knife and kept in plain water
immediately

14. Conclusion
About 120 – 150 flowers/metre sq./yr a
r
e
harvested under open conditions
Whereas, 180 – 200 flowers/metre sq./yr are
harvested under polyhouse in Assam conditions
Moreover, even though initial cost may bemore
but in the long run Greenhouse cultivation
certainly pays rich dividends.
Thus, the industry should pool it’s resourcesfor
popularizing greenhouse cultivation and the
entrepreneur should think towards the export of
gerbera.
