1. CHINESE
CABBAGE
Chinese Cabbage (Brassica rapa
subspecies), also known as snow cabbage is
a green, leafy vegetable often used in
Chinese cuisine. The vegetable is related to
the Western cabbage, and is of the same
species as the common turnip.
Chinese cabbage is believed to have
originated in China. Later, it was likely
introduced to other countries throughout the
region and then spread around the world.
Today, Chinese cabbage is available in many
countries but tends to be most popular in
Asia.
In the Philippines, it is popularly known as
Pechay or Petsay. It was one of most often
used vegetable in many Filipino dishes.
Packageof
Technology in
Producing
Chineese Cabbage
World
Scenario
Cabbage is grown over an area of
2412 thousand hectares in the world,
with a production of 69, 381 tonnes.
China is the leading producer of
cabbage in the world followed by
India. Productivity of cabbage is
highest in Republic of Korea with
72.45 t/ha.
Future Thrust
•Demand for high value
produce is growing both in
domestic and overseas market
at the same time, competition is
also increasing.
• Biotechnological tools must
be used in conjunction with
conventional breeding to tag
genes of interest. There is
need to develop varieties with
durable resistance to multiple
diseases and pests; heat,
drought and salt tolerant
varieties.
•Eco-region specific technology
generation based on maximum
productivity of available natural
resources like climatic
condition, soil fertility and water.
• Improve the understanding
of interactions between native
ecosystems and production
systems and develop best
practices to conserve
•Develop production and
post-harvest technologies to
improve product quality and
minimize environmental
impacts. • Sustainable path
for development to meet
challenges in vegetable
production through proper
technological innovations
and interventions
• Inter institutional
mechanisms to network
and review the ongoing
programmes of
biotechnology, cost effective
production technologies,
postharvest technology, farm
mechanization, transfer of
technology and organic
farming.
Chinese cabbage is grown successfully
on a range of soil types, ranging from
sandy soils to the much heavier
textured loams. The soils that are well
drained, possess good structure,
fertility and water-holding capacity
usually produce a satisfactory crop of
Chinese cabbage.

2. MICROSPRINKLER
IRRIGATION
SYSTEM
Effects of Irrigation in
Chinese Cabbage
Quick Facts…
• Micro-sprinkler irrigation is a low pressure, low
to medium volume irrigation system suitable for
high value crops such as tree fruits.
• If managed properly, micro irrigation can
increase yields and decrease water use and
fertilizer and labor requirements when compared
to gated pipe/furrow irrigation systems.
• Micro-sprinkler irrigation saves water because
of the high application efficiency and high water
distribution uniformity with little if any waste if
managed properly.
• Micro-sprinkler irrigation is ideal for irrigating
sloping or irregularly shaped orchard blocks that
cannot be flood/furrow irrigated.
• An additional increase in efficiency can be
obtained by the addition of fertilizer injection to
the system. Water-soluble fertilizers can be
injected through a microirrigation system thereby
significantly reducing cost compared to
traditional fertilizer applications.
It is therefore recommended to
adopt the microsprinkler irrigation
method to obtain a potential yield
of cabbage.
It was found that Chinese Cabbage
crop performed better with the
microsprinkler system than the
drip system. All the growth- and
yield-contributing characters in the
microsprinkler irrigation method
were significantly superior over
drip irrigation.
The Cu content in Chinese cabbage
plants was reduced significantly when
irrigation was applied, so the extra
water assured
proper plant growth conditions and
the obtaining of a healthier aliment.
Some of the additional
advantages of micro-sprinkler
irrigation systems are: the potential
for reducing frost damage, greater
control over water application times
and amounts to more closely match
local evapotranspiration (ET) rates to
maintain optimum soil moisture.
Climate Requirement for
Chinese Cabbage
Farming:-
Chinese cabbage
thrives best during the
cooler periods of the
growing season. It
prefers an average
temperature of 15°C to
22°C during crop early
growth. Temperatures
below 0°C are tolerated
for short time periods
but too low temperature
can induce premature
bolting of the crop.
Chinese cabbage is a
cool seasonal crop and
needs good amount of
water supply throughout
plant growth period.
However, The most
critical stage of
watering is during
cabbage head formation.
This crop grows best in
winter and should have
proper irrigation for
good yields.
Soil Requirement of
Chinese Cabbage
Farming:-
Chinese cabbage can be
grown on wide variety
of soils ranging from
sandy loam to textured
loam. However, well-
drained sandy loam soils
with good organic matter
are proved to be good
for excellent yield and
quality produce. The idea
pH range for Chinese
cabbage farming is 5.5 –
7.0. Lower pH soils
always lead to calcium or
magnesium deficiency
hence they must be
compensated with
required nutrients. Avoid
soils which are extremely
sandy and claylike. As this
crop requires plenty of
water, a good moisture
holding soil is very well
recommended for
growing the Chinese
cabbage.
Propagation in Chinese
Cabbage Farming:
Chinese cabbage
propagation is done from
seed. Seedling can be
raised on nursery beds or
greenhouse and can be
transplanted to main field.
Even they can be directly
sown on field beds.
Land Preparation in
Chinese Cabbage Farming:
Land should be prepared
well enough to have fine
tilth of soil. Soil can be
tilled by using fork or hoe.
Land should be prepared
at least 2 months in
advance of planting.
Chisel Plough or Disc
plough can be used to
prepare the land. Any
weeds or any plant
residues should be
removed in order to make
field weed free. In case
of sandy soils, rotary
hoed cultivation is
preferred to make a good
seedbed.
Seed Rate, Planting, and
Spacing in Chinese
Cabbage Farming:
With the single grain
seed technique, about
500–600 grams of seed/
hectare is required, for
normal and traditional
seed technique about 1 kg
of seed / hectare is
recommended. If
traditional or normal seed
technique is practiced, the
seedlings must be thinned
out after 2 to 4 weeks
after sowing. In case of
direct seeding in the field,
make a planting furrow
about 2-3 cm using a
hand hoe. Planting should
be done in seedbeds, in
row spaced 15 to 20 cm
distance. Seeds should be
sown 1-2 cm apart within
the row. Seeds should be
sprinkled into the furrow
and covered with 1 to 1.5
cm of soil.
Irrigation in Chinese
Cabbage Farming: Well,
Chinese cabbage crop
requires good irrigation
throughout its lifecycle or
growth period. The
frequency of irrigation
actually depends on soil
type, climate , and plant
or crop age. However, in
case of Napa/Chinese
cabbage it is better to
irrigate 3 times a week
for sandy soils, if the soil
is sandy loam type, it may
require 2 times a week.
make sure to maintain
constant moisture at plant
roots. Irrigation is very
critical and any water
stress should be avoided
at head forming stage. In
case of heavy rains, make
sure to drain out the water
from the field as early as
possible. Drip irrigation,
flood irrigation or micro
jet sprinkler irrigation can
be adopter for better
water utilization.
