Owing to cleaning of forests, people have started
to domesticate it in coastal Orissa.
There is a large area of spine gourd in bolangir
district, at harishankar in western part of orissa.

lamina ovate, oblong with basal lobes round at
base, stems angular, long tuberous root.
Spine gourd shows good variability in shape and
size of the leaf, fruit shape and colour.

7. Sex expression
 In its first season of growth, an F1 hybrid between a
tetraploid female and diploid male produced only male
flowers while in the following season it also produced
many female flowers.
 Sex expression had changed from dioecious to
monoecious. One female branch of the hybrid produced
hermaphrodite flowers, which were smaller in size and
deep yellow in colour like those of diploid plants.
 No fruit set occurred in hermaphrodite flowers and only
sterile pollen was produced.

12. Sowing
 Land preparation : It should be done by 4-5
ploughing and planking. A well ploughed and leveled
field helps to maintain a healthy plant stand and also
reduces the weed flora.
 Recommended spacing to be followed (if staking is
not practiced) is, 1-2 meter between two ridges and
60-90 cm between two plants. If staking is practiced,
this spacing may be reduced according to your
cultivation requirements.

13. Basins preparation
Some times basins (45 cm x 45 cm) are prepared
In the field for planting of seedlings/root cuttings/
tuberous roots.
It must be filled with 5 kg leaf mould, compost,
150 g single super phosphate and 50 g muriate of
potash each along with 3 g furadon and 75 g neem
cake.
Irrigate the basin lightly a day before planting so
that soil becomes workable.

15. Planting
Seeds : Seed have long period of dormancy and low
germination rate (50 %) further plants raised from seeds
show 50 : 50 male and female population and bear
fruits quite late (2-3 years).
 Male and female plants can only be recognized when
plants start flowering and fruiting. Due to imbalance in
male and female plant ratio, yield decreases drastically.
 In general 10 % male plants are needed in the field for
better pollination and fruit setting. Hence, propagation
by seeds is not possible.

16. Tuberous root : underground tuberous roots are
planted to take an early crop. Plants of 2-3 years old
develop more number of tuberous roots.
 Due to dioecious nature of crop tuberous roots of male
and female plants should be collected separately, which
can be recognized easily by seeing flowers and fruits.
The tuberous roots should be size of 80-120 g for
multiplication.
 For enough planting material large tubers should be cut
into pieces keeping at least two eyes in each piece. The
cut tubers must be treated with 0.2 % dithane M-45 and
seradix B no.1 powder and keep in shade for 30
minutes.

17.  Stem cutting : Two node stem cuttings of spine gourd are
collected from the identified, disease free and insect free
vines.
 These should be planted in sand beds (with rooting powder,
seradix-b), in August-September when temperature and
humidity are conducive. The planted cuttings should be
regularly watered in morning and evening
 The cuttings are rooted 15-17 days after planting in sand
beds in nursery. Then rooted cuttings are transplanted in the
main field or in pots for further growth. The best time for
planting of tuberous root is February under irrigated
conditions and first fortnight of June in rainy season and
first week of July for cutting.

18. Enough soil moisture is essential for, early
sprouting, vine growth and also for flowering
and fruiting.
Irrigation should be given once in 10 days
depending upon the soils and climatic
condition. Irrigation is given at 4-5 days
interval during dry season.
No irrigation is needed in rainy season to the
crop. When crop is over, vine dries and
dormancy is commenced then no need to
irrigate the crop.

19. Interculture
Two to three shallow hoeing is done
commencing 15 days after planting.
It keeps the soil loose and give proper
development to root and shoot system of the
plant. After each irrigation soil in the ring/ pits
should be kept loose for proper aeration and to
maintain the moisture for longer period. After
each hoeing, earthing up is necessary.

20. Training/staking:
 In order to prevent fruits from direct contact to soil which
may caused rotting, it is better to train the vine on bamboo
stakes or on bower.
 Staking at 5-6 feet height should be done for higher yield of
spine gourd after the first top dressing of fertilizer. The
branches of spine gourd should spread easily, because each
and every node bears flowers after 8-10 node from the base.
Staking is given by keeping 3 bamboo small branches in a
triangular position 30 cm away from centre. Sometimes
bowers are prepared at a height of 5 ft.
 Placing cemented poles or bamboo poles followed by cris-
cross wire netting. Training on bower or staking must be
started just after 30 cm of vine length from the ground level.

21. Weed control
 Weeding should be started after the plants have sprouted and
well set in the field. In early stage weed uprooted carefully so
the plant should not be uprooted or damage.
 Then subsequent weeding is done before top dressing of
fertilizer i.e. 35 and 55 days after planting.
 Generally manual weeding is done to control the weed from
the crop.
 Application of alachlor or butachlor @ 2.0 kg a.i./ ha give
effective control.
 Pre-emergence/ planting application of stomp 30 C @ 1 kg
a.i./ha followed by hoeing/ weeding 35-40 days after planting
and 60 days after planting is advisable to escape the critical
period of crop weed competition.

22. Nutritional requirement
 The farm yard manure/compost @ 20-25 tones/ha should be
incorporated in soil at final land preparation or apply in pits.
Fertilizer dose of 60:40:40 kg, N:P:K/ha is recommended
for maximum and economic yield from the crop. Mix full
dose of phosphorus and half of potash in the pits at the time
of planting.
 Full amount of nitrogen should be given into three splits.
First split dose (20 kg/ha) of nitrogen should apply 15-20
days after planting. Second split of nitrogen (20 kg/ha)
along with half of potash (20 kg/ha) should be given as
second top dressing 35-40 days after planting. Rest of the
nitrogen (20kg/ha) apply as third top dressing 55-60 days
after planting.

Some time larvae attack on roots. Maximum
damage is observed from mid june to august.
Control : 100 g carbaryl 50 % WP dissolved in
100 liters of water and spray alternatively at 15

mildew first appears on the under surface of the
older leaves, as white fluffy circular spots, which
increase in size and number, coalesce and
eventually cover both the surfaces. Severely
attacked leave become brown and shriveled. The
fungus attacks the leaves, stem and fruits. Spray
0.03% karathane at weekly interval for effective
control of the disease.

 Spine gourd is generally propagated by tuberous roots and stem
cuttings. For this purpose good spine gourd vine which has medium
sized fruits (10-15 g), dark green in colour, tough and false spines,
quick edible maturity (30-35 days after flowering); minimum yield
potential (2 kg/ plant) and resistant to epilachna beetle and fruit borer

evening. The cuttings are rooted 15-17 days after planting. Then
rooted cuttings are suitable for the planting in main field.
 The tuberous roots of selected genotype are collected after crop is over

times the tubers of new genotype are stored in refrigerators and reused
as planting material for the next year production.
