an agreeable flavour after boiling.
◘
◘
Once establish, will produce for many years (Perennial crop).
◘
◘

Slide 6
Propagation
The two methods by which plants can be procured and propagated
By purchasing the plants from a seeds man or some grower.
By Purchasing or sowing the seed from which to raise them.
The first method is the quickest way to start a good crop in a
bed and also the most easily disposed off.
Asparagus crowns are raised from seed planted in a wellprepared seed bed.
The plants are allowed to grow for one full growing season
before being planted in permanent bed
Only one year old shoots will produce more and large spears
and yield profitable crops for a longer period.

Slide 10
Irrigation
╬
╬
╬
Asparagus beds should be well drained by means of open
furrows.
Water logging would be harmful.
Irrigating asparagus with 25 mm water per week during the
fern growing stage as a continuing operation is recommended
to obtain high yield.
Weed Control
╬
╬
╬
Most of the grassy and perennial weeds in H.P. are controlled
by the use of Paraquat @ 2-3 kg a.i./ha before emergence of
spears
2,4-D @ 2 kg a.i./ha after the harvesting of spearsand
Glyphosate @ 2 l/ha is used before the emergence of spears
and again at the end of harvesting.
Slide 11
Blanching
♠
♠
♠
Mounting the soil over the rows in asparagus beds is practiced
to blanch the young spears.
With a disc harrow, hilling is done in case of large scale
plantations before the commencement of growth or where
blanching is required.
It is also a common practice that after harvesting the green
asparagus for fresh market, mounding the row with soil is done
to bleach the asparagus for canning.
Slide 12
Harvesting and Market Preparation
☻ The normal harvest period for a fully developed asparagus bed is 8
weeks.
☻ Harvest the spears from 3 or more years of plant growth otherwise
affect the plant growth.
☻ After 7-8 years of planting a fully developed asparagus fields yield
40-50 q/ha.
☻ The spear length should be approximately 8-10 inches (20-25 cm) at
cutting with spear tips tightly closed.
☻ Once spears have been harvested they must be cooled immediately
to 32-36oF (0-2oC).
☻ Cooling preserves the sugar content which alongwith fiber content is
important in quality.
☻ Harvested spears are prepared for market by grading, sizing and
bunching.
☻ Grades are based on freshness, length and diameter of the stalk,
colour of the spear, tightness of spear tip and extent of bruising.
☻ Spears of large diameter are considered to be superior in quality.
☻ Asparagus is a very perishable crop and storage is not recommended.
☻ If market conditions demand, spears may be held at 0-2 oC and 95%
RH for no longer than 2-3 weeks.
Slide 13
Slide 14
Disease and Insect Pests
Slide 15
Diseases
The major diseases of asparagus are Rust, Fusarium root rot,
Fusarium crown rot, Phytopthora spear rot, Botrytis blight and
Virus.
Asparagus rust can be controlled through:
☻ Tolerant cultivars.
☻ Proper management practices.
☻ Clean cutting and burning old canes each year.
☻ Use of fungicides like zineb when fern growth resumes after
harvest.
☻ Fusarium crown and root rot can be controlled through:
1. Selecting tolerant (vigorous) cultivars.
2. Growing plants from treated seed on sterilized medium.
3. Using field locations not previously planted with asparagus.
4. Use of fungicides.
5. Avoid stress (drought,, poor drainage, poor fertility etc.).
Slide 16
Insects
Damage from insect infestation is confined to asparagus beetles,
Tarnished plant bug, Alfalfa plant bug, Asparagus miner, Aphids
and several soil larvae.
Asparagus beetle can be controlled through:
☻ Maintenance of clean bed.
☻ Elimination of over-watering debris and any wild asparagus near
the production area.
☻ Use pf insecticides like [email protected]%.
Aphids can be controlled through:
Maintenance of clean bed during the cutting season will prevent
first generation females from reproducing.
Disyston is effective as a control for asparagus aphid.
Insecticides like Malathion@ 0.05% is also effective in controlling
the aphids.
No insecticide provide certain control to the asparagus miner,
however
several
insecticides
like
[email protected]%
Slide 17
Soil Insects
◘ Cutworms cause damage to spears prior to emerge and cause
◘
◘
◘
spears to curl and stunt.
It is also thought that damage may encourage disease infection.
Wireworms and grubs feed on the roots of grasses, and
asparagus planted in the field previously in sod may suffer
some damage.
Any insecticide like malathion, disyston etc. should be applied
in advance of planting not after the plants are established.
