cultivated for its fleshy leafstalk and seeds.
✓It is a minor vegetable crop in India not grown in commercial
scale.
✓It is rich in several vitamins and minerals including vitamin

❑It is widely grown in Europe, USA, South America,
Australia, New Zealand and South Africa.
❑In India for seed purpose mainly grown in Punjab, Uttar
Pradesh for export for condiments.
❑In India celery is grown on a small scale in Punjab,
Uttar Pradesh, Himachal Pradesh, Tamil Nadu,
Karnataka and Kerala for its leafy stalk as vegetable

5. ❖Celery is a cool season vegetable crop.
❖Ideal temperature for growing celery is 16º-21ºC.
❖Seeds go dormant when soil temperature rises above
25ºC.
❖At 15-20ºC, seed germination is optimum.
❖Bitterness develops in leaves as the temperature rises.
5

6. ➢It grows well in deep, fertile, well drained silt loam or
loam soil .
➢Soil should be rich in organic matter.
➢As it is a shallow rooted crop well pulverized soil is
recommended.
➢pH between 5.5 and 6.7.

•Seeds are sown in July – September in plains.
•In temperate region celery is cultivated in 2
seasons.
•So sowing is done in March – April and August –
September.

8. ➢Well decomposed FYM is applied @ 10 kg/m².
➢Nursery beds with 10m length, 90cm width and a height
of 15 cm should prepared.
➢Seeds are soaked in water overnight before sowing for
better germination.
➢10-15 days before sowing, the nursery beds are sterilized
with 1% formaldehyde.
➢The beds are covered with polythene sheet for 3-5 days
after being drenched with formaldehyde.
➢Beds are kept open for 5-6 days.

❖Before transplanting the seedlings should be hardened
by withholding irrigation for obtaining better crop.
❖At 40-60 days after sowing when the seedlings attains a
height of 8-10cm the seedlings are ready for
transplanting.
❖Only disease free seedlings are used for transplanting in
main field.

20-25 t/ha 200 kg/ha 100 kg/ha 150 kg/ha
Before sowing, the full doses of P and K as well as half
of N should be applied.
Remaining half of N is applied in 2-3 split doses as d
topdressing.

➢Celery needs frequent irrigation.
➢Irregular irrigation may result in black heart in celery.
➢In summer irrigation should be given after every 7-8
days
➢In winter irrigation should be given after every 10-15
days

12. ❖Weeding
▪Hand weeding, frequent light hoeing is done to control weeds.
▪Application of Fluchloralin @1-1.25 kg/ha or Linuron @5 kg/ha
before transplanting of crop are effective in controlling weeds.
▪Earthening up is done when plant attains a height of 40cm.
❖Blanching
▪It is an important operation carried out in celery for preventing
chlorophyll from developing in the leaf stalks while the plants are
still growing.
▪It is done by wrapping paper over the leaf stalks or covering the
petioles with soil.

❑Blackheart
•Breakdown of young leaf tissues in the heart of the plant.
•Affected young tissues turn black.
•Caused by calcium deficiency.
❖Management
•Avoid wide fluctuation of soil moisture.
•Drench application and foliar spray of double calcium.
❑Chlorosis
•Yellowing between the leaf veins and early leaf fall.
•Caused by magnesium deficiency.

❖Damping off (Pythium sp.)
•This disease affects the young seedlings at just beneath the
surface.
•Affected plants fall to the ground.
➢Management
•Good drainage facility
•Seed treatment with Thiram or Captan @2.5 g/kg of seeds.

❖Root rot (Pythium polymastum)
•The affected plants remain stunted and leaves rosette.
•Later the whole plant wilts and dies.
➢Management
•Proper drainage facility should be adopted.
•Affected plants should be uprooted and destroyed.

16. 16
❖Celery leaf miners (Liriomyza trifolii)
•The small maggots form tunnels by mining inside the leaves.
➢Management
•Maggots should crushed within their tunnels
•Spraying of Monocrotophus 36% SL.
❖Aphids (Myzus persicae)
•Feeds on under side of leaves turning them yellow.
•Aphids exude honeydew, that promotes formation of sooty mould
on plants.
➢Management
•Spraying Thiamethoxam 25% WG.

17. 17
➢Requires 75-90 days after transplanting to become
ready for harvesting.
➢The plant is cut a little below the soil surface with sharp
knife so that all the leaves remain intact.
➢Average yield is about 35-60 t/ha
➢Celery can be preserved for 2-3 months at 0ºC
temperature and 95-98% relative humidity.
