Introduction
|
|
| |
Cabbage
is one of the most popular winter vegetables grown in
India. It is cultivated in 0.245 M ha with the total
production of 5.617 M mt and average productivity of
22.9 mt/ha. The major cabbage producing states are Uttar
Pradesh, Orissa, Bihar, Assam, West Bengal, Maharashtra
and Karnataka. Among these states West Bengal contributes
1.929 M mt of cabbage from 65,000 ha area with an average
productivity of 29.6 mt/ha. Cabbage is used as salad,
boiled vegetable and dehydrated vegetable as well as
in cooked curries and pickles. Cabbage is rich in minerals
and vitamins A, B1, B2 and C. |

Crop
varieties |
|
| |
Cabbage
(Brassica oleracea L. var. capitata) belongs to the
family Cruciferae. Advance technology in cabbage production
utilizes hybrid verities like Green express, Green Boy
and other verities are Pusa Mukta, Pride of India, Pusa
Drum Head, Hari Ram Gole etc. |
|

|
|
| |
Conventional
practices |
|
| |
Generally
farmers grow locally available varieties and adopt check
basin or furrow method of irrigation. Standard practices
of nutrient and plant protection measures are rarely
adopted. |
|
| |
|
|
| |
Suitable
agro climatic conditions |
|
| |
The
cabbage plants thrive in a well relatively cool moist
climate. In the plains it is grown mainly as a winter
crop, whereas in the hills it is grown as a spring and
early summer crop. |
|
| |
|
|
| |
Suitable
soils |
|
| |
Sandy
loam soil is generally considered most suitable for
an early maturing crop, but where higher yield is the
main criterion, clay loam or silt loam soil is more
suitable. It does not grow well in highly acidic soils.
The optimum pH range for cabbage is between 5.5 and
6.5. |
|
| |
|
|
| |
Preparation
of land |
|
| |
The
field should be deep (20-25 cm) ploughed with soil turning
ploughs. Thereafter, two to three cross harrowing is
done to make soil friable and loose. One or two plankings
are also needed to make the surface smooth and level.
|
|
| |
|
|
| |
Soil
sterilization |
|
| |
The
sterilization of the soil can be achieved by both physical
and chemical means. Physical control measures include
treatments with steam and solar energy. Chemical control
methods include treatments with herbicides and fumigants.
Soil sterilization can also be achieved by using transparent
plastic mulch film, which is termed as soil solarization.
During soil solarization, the incoming solar radiation
penetrates the transparent plastic film and is absorbed
in the soil. The absorbed radiation converts into heat
energy, which raises the soil temperature and kills
many soil-borne organisms including plant pathogens
and pests. |
|
| |
|
|
| |
Planting |
|
| |
The
seeds are sown in raised nursery beds. They are sown
in August-September for the early crop and in September-October
for the late crop. The seed rate is 500 g/ha for the
early crop and 375 g/ha for the late crop. Poly house
may be used for providing favourable climate for the
germination of seeds and seedlings raising. Four to
six weeks old seedlings are used for transplantation.
Generally, a spacing of 45 cm x 45 cm is kept for the
early varieties and 60 cm x 45 cm for the late varieties.

Irrigation
scheduling |
|
| |
Cabbage
requires continuous availability of moisture in soil.
Heavy irrigation should however be avoided when heads
have formed. Irrigation after long dry spells causes
bursting of heads. Drip irrigation is the most suitable
method of irrigation, which provides uniform supply
of water. The estimated daily irrigation water requirement
of cabbage crop is 4.66 l/4plants during early stage
and 6.62 l/4plants during peak growth stage. Daily irrigation
or on alternate days with On-line type of drippers is
preferred. |

| |
Application
of fertilizers |
|
| |
Cabbage
is a shallow rooted crop with high nutrients requirement.
For the best results 20-25 t/ha of FYM is incorporated
in the soil about three week before transplanting. N,
P and K fertilizers are applied respectively @ 100 kg
N, 125 kg P and 150 kg K per hectare before transplanting.
Three to four split doses of liquid nitrogen (100 kg
N/ha) should be applied through drip irrigation after
5-6 weeks of transplanting. |
|
| |
|
|
| |
Weed
control |
|
| |
Shallow
hoeing should be done for weed control. Black plastic
mulch is also effective in restricting weed population. |
|
| |
|
|
| |
Plant
protection |
|
| |
The
control measures for insects, pests and diseases depend
upon type and intensity of problem. The control measures
for the main pests and diseases are stated below. |
|
| |
Cabbage
Maggot: It attacks on the young rootlets and on the
main root, causing wilting of plants. Application of
Calomelis suspension has been prescribed as a control
measure. |
|
| |
Damping
off: It is common disease in the nursery-beds of the
early cabbage. It is controlled by soil solarization
using transparent plastic film or by drenching the nursery
beds with fungicide 3-4 weeks prior to sowing of seeds. |
|
| |
Downy
Mildew: It is characterized by the appearance of purplish-brown
spots on the underside of the leaves. The causal organism
is an obligate parasite present in soil. Sanitation
and crop rotation help reduce the infection of Downy
Mildew. |
|

|
|
| |
Harvesting,
yield and quality control |
|
| |
Cabbage
is harvested when the head is of suitable size, firm
but tender. The average yield of cabbage varies from
100 to 115 t/ha under drip irrigation with plastic mulch.
In attaining quality of cabbage grading should be done
according to the size and quality as per the standards
laid down by the Indian Standards Institution. |
|
| |
|
|
| |
Post
harvest handling and storage |
|
| |
The
best storage temperature is 00 C at 90 to 95 per cent
relative humidity. |
