GREENHOUSE TECHNOLOGY ?
A greenhouse (also called a glasshouse) is a
building or complex in which plants are
Growth and healthy production of plants
under controlled favorable conditions in
closed or partially closed space is called
Types – Glass House, Shade Net, Poly
Importance of Greenhouse technology
Best way of utilizing the potential of Gerbera
Efficieny utilization of chemicals &fertilizers
Water requirement is limited & easy to control
Yield may be 10 – 12 times higher under suitable
Export oriented view
Major beneficiary to small holding farmer
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 .
General disinfection of soil by
covering the soil with plastic for
6 – 8 weeks(Solanization)
Bed preparation as recommended by Kumar Florist (2007)/ K.F.
Planting medium should be adequately porous and
Two –row or 4-row planting systems are generally
Planting can be done round-the-year but preferably
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.
Division: – Propagation through division of clumps is the most
Disease and pest free plants
4 – 5 leaves per plant at planting time
Crown should be 1 – 2 cm above soil
Gerbera flowers are harvested
when outer two whorls of disc
florets are perpendicular to the
Harvested with the help of sharp
knife and kept in plain water
About 120 – 150 flowers/metre sq./yr are
harvested under open conditions
Whereas, 180 – 200 flowers/metre sq./yr are
harvested under polyhouse in Assam conditions
Moreover, even though initial cost may be more
but in the long run Greenhouse cultivation
certainly pays rich dividends.
Thus, the industry should pool it’s resources for
popularizing greenhouse cultivation and the
entrepreneur should think towards the export of
