large blooms that radiate outwards from the top of the plant.
2.
Gray Goldenrod- It
is a smaller golden rod species, typically with small number of blooming

4.
Stiff Golden Rod- It
blooms cluster at the top of the plant, not spreading out.It’s leaves are short
with a rubbery texture.
Important uses:
Ø It
is used as cut flower.
Ø It
is used as filler material in flower arrangement and vases.
Ø It
can be used as dry flower.
Ø It
is used for extraction of essential oil.
Ø It
can be grown as pot plant.
PLANT CHARACTER
It
is a herbaceous perennial plant growing upto a height of 2.5 meters.Leaves are
simple with alternate arrangement, ie, one leaf per node.
CLIMATE
It
can be grown in varied climatic conditions of temperatures ranging from 27 to
30 degrees Celsius, while the cooler climate gives high quality cut flower.
SOIL
Well
drained sandy loam and well drained red loam soils are suitable.
VARIETIES
Important varieties of goldenrod are :
Ø GOLDENGATE
Ø GOLDENWING
Ø TARAGOLD
Ø PETERPAN
Ø BALLARDI
Ø SUPER,MONTE
SOLO
Ø MONTE
D’ORO.
PROPAGATION
Goldenrod
is propagated through division of suckers or clusters.It canbe propagated by
seeds also.
FIELD PREPERATION
Plough
the soil 2-3 times and make fine tilth.Take flat beds
SPACING
The
slips are planted at 45cm*45cm spacing.
IRRIGATION
Irrigation
is done normally once in 3 days depending upon soil moisture content.
MANURING
Ø NPK@140:175:150
kg/hectare
Ø FYM
@5tonnes/hectare
Ø These
should be given as basal dose at the time of field preparation.
Ø Half
the dose of NPK should be top dressed after every harvest.
WEEDING
Weeding
should be done as and when required.
PLANT PROTECTION
PEST:
Lace bugs- It
sucks sap from different plant parts like leaf,twig and flower.Apply some
biopesticides to control lace bugs.
DISEASES:
1.
Powdery mildew- Powdery growth of fungus can be seen on leaf
surface.Later the affected part dries up.
2.
Leaf spot-
Brown spots appear on leaf. Later it spreads over leaf and dries up.
3.
Root rot- Rotting of roots leads to total collapse of the
plant.
To control these diseases ,apply Pseudomonas
fluorescence.
HARVESTING
First
harvest can be done 75 days after planting. Then harvesting can be repeated at
30 days interval up to 2 years.
HARVESTING INDEX/STAGE
Harvesting
can be done 25% of the flowers have opened in the inflorescence.
YIELD
3Lakh
stems/crop/hectare is the average yield .
POST HARVEST MANAGEMENT
1.
Pre cooling:
After harvesting, put the cut flowers in clean water
immediately. It will help to remove
field heat.
2.
Grading:
Grading of cut
flowers depends on Length of stem, color and appearance of inflorescence and
size of inflorescence.
3.
Bunching:
Flowers are
grouped into bunches of 5-20 stems and loosely tied with rubber bands.
4.
Packing:
Bunches are
wrapped with suitable packing materials like clear polythene sheet, craft paper
or corrugated cardboard sheet.
VASE LIFE
Vase
life can be increased by using holding solution. Aluminium sulphate @1000ppm +2%
sucrose +8HQC@100ppm(Hydroxy Quinoline Citrate)solution can be used for
prolonging vase life.
VALUE
ADDED PRODUCTS
1.
Dry Flower:
Take newly
Opened flowering stem .Hang it upside down in an airy place in the shade
2.
Essential oil:
Essential oil is extracted by steam distillation of
leaves, stem and flower. It is used to enhance the appearance of healthy
looking skin.
