14. TYPES OF
ASPARAGUS
There are mainly four types of
Asparagus :
Green Asparagus
Purple Asparagus
White Asparagus
Wild Asparagus
Add a Footer 14

15. GREEN ASPARAGUS
 This is the main cultivated
type of asparagus.
 About 60% of asparagus is
green asparagus .
 The stems are use for
vegetables.
Add a Footer 15

16. PURPLE ASPARAGUS
 Purple asparagus is a similar in
appearance.
 Higher sugar content than other
asparagus varieties.
 Purple asparagus colour comes
from the high levels of
anthocyanins in the spears.
Add a Footer 16

17. WHITE ASPARAGUS
 White asparagus is simply
green asparagus that has
never seen the light of day.
 Medicinal value is very high .
 The plant is grown under soil
or some other covering to
block out the sun's rays.
Add a Footer 17

18. WILD ASPARAGUS
 This is a type of
asparagus which grown
naturally .
 Mainly grown in the wild
area.
 They are mainly toxic &
sub-toxic.

20. SOIL
TEMPERATURE
CLIMATE
Add a Footer 20
Soil :
Loamy sandy soil
Well drained and fertile soil
pH = 6.0 - 7.5 climate :
Production well in mild to cold climates .
Asparagus can be grown in a wide range of
soils and under various climatic conditions
.
moist climatic conditions .
Climate withstands frost .
Needs full sunlight for growth (long day
plant).
temperature :
 A cool season crop
 For Favoring productivity the
optimum temperature is
24°C - 30°C (In day)
13°C - 19°C (In night) .

21. PROPAGATION
SEED RATE
NURSERY
Add a Footer 21
PROPAGATION :
 From seeds and crowns
Nursery raising :
 Asparagus is raised through seed as
well as crowns .
 Time for raising nursery bed ;
Seed rate :
 600 gm. /ha to raise
the nursery .
Mid hills High hills
March - June April - May

22. PLANTING
Add a Footer 22
Time of planting :
Planting distance / Spacing :
 Spacing should be 150 cm. × 45 cm.
 Crown is planted in furrows .
 The width of furrows are 30 cm. and
deep of furrows are 25 cm.
Depth of planting :
 20 – 30 cm. approx.
 Density of plants 30000/ha .
Mid hills High hills
January March - April

23. FERTILIZER RECOMMENDATION
 Half of FYM + Half of NPK apply in spring season .
 Nitrogen should be applied in 3 – 4 split doses during
planting and harvesting .
 After harvesting , every year about 20 – 30 kg/ha Nitrogen
are applied for better growth .
 Remaining half of the fertilizers should be applied after
cutting of spears .

24. IRRIGATION
WEED CONTROL
Add a Footer 24
IRRIGATION:
Well drained (open
furrows) beds .
Water logging would
be harmful .
Irrigating asparagus
with 25 mm water per
week during the fern
growing stage .
WEED CONTROL :
Most of the grassy and
perennial weeds in H.P. are
controlled by the use of
paraquat @ 2-3 kg /ha before
emergence of spears .
2,4-D @2 kg /ha after
harvesting of spearsand .
Glyphosate @ 2-3 kg /ha
before emergence of spears
and again at the end of
harvesting .

25. INSECT
Main insects are
Asparagus beetles
Aphids
Plant bugs
Alfalfa plant bugs
Asparagus miner

26. CONTROL OF
ASPARAGUS BEETLES
CONTROLLED THROUGH :
Maintenance Of Clean Bed .
Elimination of over-water
debris and any wild asparagus
near the production area .
Use pf insecticides like
malathion @ 0.05% .
Add a Footer 26

27. CONTROL OF APHIDS
CONTROLLED THROUGH :
Maintenance of clean bed
during the cutting .
Disyston is effective as a
control for asparagus aphid .
Use pf insecticides like
malathion @ 0.05% ,triazophos
@ 0.15% .

28. DISEASES
The major diseases are
Rust
Fusarium crown
Spear Rot
Blight
Virus
Add a Footer 28

29. CONTROL OF RUST
CONTROLLED THROUGH :
Tolerant Cultivars .
Proper management .
Use fungicides like zineb after
harvest .
Clean cutting and burning old
canes each year .
Add a Footer 29

30. CONTROL OF
FUSARIUM CROWN
CONTROLLED THROUGH :
Tolerant (vigorus)Cultivars .
Treat the seeds with sterilized
medium .
Use fungicides .
Avoid stress (drought , poor
drainage , poor fertility etc.) .

31. MANAGEMENT
HARVESTING
BLANCHING
YIELD
STORAGE

32. BLANCHING
Add a Footer 32
Practiced to blanch
the young spears .
A common practices
after harvesting the
green asparagus.
Hilling is done in case
of large scale and here
blanching is required .
We should do the
blanching to detoxify
the plant and
inactivating the
activated enzymes .
Asparagus is one of the
earliest spring vegetables.
Time period of fully matured
asparagus minimum three(3)
years and maximum seven -
eight(7 – 8) years from
planting .
Normal harvest period for a
fully developed asparagus
bed is 8 weeks.
The spear length should be
approx. 20-25 cm on the time
of harvesting .
Harvested by cutting 3 – 4 cm
below the surface soil .
HARVESTING

33. YIELD
Add a Footer 33
After 7-8 years of planting a
fully developed asparagus
fields yield About 40-50 q/ha .
• Mature asparagus are
stored for future .
• The spears may be held at
0°C -2°C and 95% RH for no
longer than 14 – 18 days .
STORAGE
