The Versatile Safflower: History, Uses, and Benefits

Safflower
 Carthamus tinctorius
It’s a member of 
asteraceae/compositae
. 
It’s a minor oil seed crop because of limited distribution and
farmer’s dont like to cultivate because of spiny nature.
In India it is grown in century either for its orange, 
red carthamin
extracted from brilliantly colored flower heads and or for much
value oil.
Synthetic dyes are come in to market. This has lead to almost
disappearance of crop from its traditional areas of north and north
east Asia.
 Now it is mainly confined to peninsular india.
Safflower is described as "Kusumbha" in sanscrit literature and
most commonly "Kusum". Carthamus is latinised version of Arabic
word "quartrum" or "qurtum" which also means color of dye
obtained from flower heads.
Safflower produce oil rich in PUFA which is good for blood
cholesterol control and it is also considered as good cooking oil used
in preparation of salad and resins.
Safflower oil is highly suitable frozen desserts as oil remain liquid
even in frozen state.
Oil is valued in technology of alkyd resins, used for manufacture of
roghan, meant for preservation of leather, charred oil is used in
healing of psoriasis and rheumatism.
 Safflower is used in liquid formulation and also effective as non
allergic dispersant for injectable medicines.
Dry red and orange flower has sold as substitute for saffron in middle
east countries. 
Flower is used in treating of circulatory system, inflammation
muscular faligue.
Safflower cake is used to feed ruminents and manogastric animals.
Hulls can be used in preparation of cellulose insulation boards.
Safflower leaves rich in carotein, riboflavin, young seedlings twigs
are used as vegetable salads.
Green safflower plant is used as fodder and also used after silage.
Origin and 
History
:
 
According to Vavilov (Expert taxonomist),  
Eastern type
 must
have originated in India, or Ethiopia, while the 
western type 
must
have originated from Fertile Crescent (Turkey, Syria and
Lebanon)
Plant is primitively identified as growing about 4000 years ago.
Genus 
Carthamus
 has 25 species having different pairs of
chromosomes 10, 11, 12, 22, 32.
Only 
Carthamus tinctorius 
is cultivated and other species are wild
in nature. 
Carthamus tinctorius 
is supposed to originate from
 C.
lanatus
, 
C. oxycantha
, 
C. palestinus.
Area and distribution
Safflower is grown in Africa, Latin America, North America,
Australia and  Africa besides Asian counties.
Its major producers are India (2.32 lakh hectare), Kazakhstan
(2.44 lakh hectare), Agrentina (1.61 lakh hectare) , Mexico (1.72
lakh hectare)  as well as USA (0.65 lakh hectare) and China,
Ethiopia, Tanzania and Turkey  growing it on minor scale.
Turkey and USA having a productivity of 1250 kg/ha, Mexico
1390 kg/ha, India 655 kg/ha. Global productivity is 845 kg/ha.
In India, it is predominantly grown in the states of Maharashtra
(1.64 lakh ha), Karnataka (53,000 ha) and Andra Pradesh.
Botanical description of plant
Safflower is highly branched herba varying in height from 30-150
cm.
Root: 
Plant has deep fleshy tap root system producing numerous
thin laterals. Tap root penetrates to a depth of 1.5 – 3 metres.
Stem:  
Stem is thick, cylindrical thick at base and become thinner
as branching increases. Stem is smooth glabrous grey white in
colour with longitudinal grooves on stem. Stem becomes brittle at
the time of maturity. Central stem branches at an height of 15-20
cm. Pattern of branching is a varietal character.
Leaves
 are deeply serrated at the base and ovate at the top.
Inflorescence consists of numerous flowers collected closely
together at circular and flattened receptacle.
Leaves

Flowers: 
Inflorescence consists of numerous flowers collected
closely together at circular and flattened receptacle.
Fruits
: The number of fruits varies with variety and varies from 80-
120. Fruit is called as achene, resembles small rectangular sunflower
seeds and more thick and fibrous than sunflower.
Test weight of seed is 2.5 to 8.08 g.
Depending on cultivar safflower produces
20-100 developed seeds in each heads.
Hull constitutes 30-64%.
Seeds after planting take six days to germinate and depend on soil temperature. First
stage is rosette. It remains in that stage till temperature become favourable.
It is a thermo sensitive crop. It forms rosette of basal leaves. During slow growing
rosette stage, tap root develops and penetrates deep into soil. Subsequently central
stem grow rapidly and branch extensively.
Flowering normal begins at head region and proceeds centripetal and requires 3-5
days to complete. Since plant is multifloret, time to flowering extends to 5-8 days.
Time of flowering has genetic control and is greatly influenced by environment.
Seeds will be set at after 8 days after flowering. Safflower is basically self
pollinated crop. But bees and other insects are necessary for optimum and
maximum yield. Bees can increase yield for 5%.
Physiology: 
It is a C
3
 plant. It is not having as much productivity
as that of sunflower. The duration of crop varies from 140-240 days
because of multiflowers.
 Leaf area index of 4 to4.5 is observed at vegetative growth. Yield
is highly correlated to 1000 seed weight that varies from 40-60 g.
Plasticity of plant density is significant.
Population varies from low to high with same yield levels. Yield
levels are similar with 6-90 plants/m
2
.
 Important yield parameters are number of capsules/plant, diameter
of capsule, number of grains/capitulum and test weight.
Climatic requirement
Safflower is best grown in cool season of tropical and subtropical region
and rarely in temperate region.
It requires cool climate in the initial stage (15
o
C), but warm temperatures
between 24-32
o
C and dry hot climates during maturity (30-35
o
C).
Freezing temperatures at flowering  may result into sterility. Continuous
rains at flowering or even in the initial stages may damage the crop.
 It is
drought tolerant crop and can extract subsoil moisture.
Climatic condition during crop growth affects soil moisture
because of hot dry winds and adequate moisture of 300 mm of
rainfall produces excellent yield if rainfall occurs prior to
flowering.
In India, area receiving rainfall of 600-1000 mm is being used for
obtaining higher yield depending on soil types.
Prolonged rainfall at flowering adversely affects pollination and
fertilization causing discoloured seeds and small seed production.
Crop cannot tolerate water logging at any stage of crop growth.
Soil requirement for safflower:
 
Safflower can be grown in any well drained soil, but it is preferred to grow in
clay rich soil with high water holding capacity.
Safflower requires fertile deep and well drained soils because safflower can
withstand drought but not waterlogging. Irrespective of fertility, shallow soils
produce lower yields due to inadequate storage capacity of moisture.
Water logging due to poor drainage as well as prolonged rainfall for shorter
periods predisposes crop for damage of rootknot, wilt and decreases yield.
 Heavy soils with poor drainage should be avoided for safflower.
Safflower is considered to be salt tolerant next to barley and cotton. It
produces profitable yield even it is grown in saline soils.
 It is also having alkalinity tolerance similar to barley in rainfed condition.
Cropping system:
 It can fit, well in any cropping sequence
and Inter cropping systems.
Sequence cropping system:
Karnataka- Moong bean-Safflower,
 
       
Soybean- Safflower
 
       
Ground nut- Safflower.
In scanty rainfall areas of Karnataka, AP it is grown after
sorghum/Moongbean/maize/Sorghum-Safflower.
In assured rainfall areas Moong bean/Hybrid sorghum/Ground
nut/Sesamum/Sunflower-Safflower.
Drought prone areas of Maharashtra - Moong bean/ Urd
bean/Soybean/Maize/Ground nut- Safflower.
Intercropping system:
Maharastra –
 Cowpea/Chickpea+ Safflower 3:1/2;1
Wheat+ Safflower, Linseed+ Safflower 4:1
Coriander+ Safflower 3:1
In Karnataka-
Chickpea+ Safflower 3:1
Wheat+ Safflower 3:1
Coriander+ Safflower 2:1
In AP-
Chick pea + Safflower 3:1
Wheat+ Safflower 3:1
Linseed+ Safflower 3:1.
Varieties:
 Large number of crop varieties have been hybrids are
developed in this crop.
AP-
   Hybrid- DSH-129, MKH-11, NARI-NH-1, NARI-6.
      
 
  
Varieties- Manjira, Sagar muthyalu, Parbani kusum, Phuli kurum
Karnataka-
 Varieties: S-144, A-1, A-300, A-2.
Maharastra-
 Varieties: Bjhima, Sharada, Girnaur.
Safflower requires clod free seed bed but does not require fine seed
bed because fine seed bed forms crust immediately after rain and
from subsoil is there should be enough moisture for germination and
earlt establishment.
In black soil of rabi areas, 3-4 harrowings during monsoon areas is as
good as deep ploughing to keep fields weed free and also helps in
conservation of moisture.
To ensure greater weed control last harrowing should be done just
prior to sowing because initial rosette stage is slow and smothering
effect on weeds.
 If plots are infested with objectionable weeds, deep ploughing is
necessary during summer.
Land preparation
Presoaking and seed treatment:
Presoaking for 24-48 hours induces seed hardening in safflower
induces drought tolerance.
Soak seeds in water for 24-48 hours followed by shade drying
for 4 hours and the treat with application of fungicides because
many of diseases are seed borne in safflower.
Therefore seed should treated with capton, Thyram/bavistin @
3g/kg seeds.
Seed rate and spacing:
 
Safflower has plasticity to seed rate because of its
inherent branching potential.
Optimum plant population in different conditions will never exceed 1,11,000
plants/ha.
Seed rate depends on spacing, depth of sowing, previous crop grown, it
varies from 7-20 kgs /ha.
In peninsular India and northern India wide row spacing of 30-45 and 90 cm
didn’t cause any striking yield difference. Normally 45-60 cm row spacing is
higher for safflower.
 AP- 7.5-10 kg/ha- 45x20 cm,
 Karnataka-7.5 kg/ha-45x20 cm
 Maharastra - Kharif fallows-10-12 kg/ha-45x20 cm
When ever soil moisture is favourable excess seedling should be thinned
with in 15-20 days.
Manures and Fertilizers
Application of manure before final preparation of land @5-8 t/ha
(heavy soils) or 12-15 t/ha (sandy and light soils) is necessary for the
sole crop.
For intercrop, no separate dose of manure is given, when the same is
applied to the main crop.
A dose of fertilizers @ 40:40:20 kg N, P
2
O
5
 and K
2
O per ha is
necessary for the sole crop.
For intercrop, one-fourth to one-third dose is necessary o be
supplemented with the fertilizers given to the main crop.
N requirement:
 
If preceeding crop is legume then 50% of N dose is
reduced. In scanty rain fall areas, either top dressing of 20-25% is given.
If soil moisture is favorable and post raining is expected/irrigated
condition 50% basal and 50% top dress is better at 5 weeks later at time
of 1
st
 irrigation.
P requirement:
 is moderate and minimum requirement has to be
applied even when previous crop is applied with large quantity of P.
Safflower responds very well to P in seedling stage. Safflower is deep
rooted crop it draws more P from lower area. Therefore it is capable of
drawing P from more volume of soil.
K requirement:
 Application of K is usually unnecessary except in areas
where deficiency is existing. In general, application of K to preceding
crop is sufficient to safflower. It responds to 30 kg S and response to
any fertilizer depends on method and time of application.
Response to nutrienst
It is better to apply full quantity of fertilizer as basal in rainfed
situation and placed 10 cm below surface.
 Under irrigated condition it is better to apply 50% N and full P and
K as basal and 50% N top dress after 5 week after sowing.
Beneficial effect of seed treatment with Azospirillum, Azatobacter,
VAM and when applied in combination with FYM 6 t/ha + 20 kg N
was found to increase yield by 42%.
The biofertiliser also helps in increasing WUE thus alleviate
harmful effects of drought and frost.
Water management
As the crop roots are able to extract the soil moisture from deeper
layers (even upto 1-1.5 m) in majority cases, it is grown as un –
irrigated crop.
In case of sandy and lighter soils, it may be advantageous to
irrigate once after 30-35 days.
 Its water requirement is 
30-35 cm, 
and hence can be grown under
limited soil moisture.
Weed control
Critical period for competition by weeds extends up to 40 days,
till stem elongation and branching do not happen.
Control of the weeds till such time by hoeing after 20-40 days of
sowing will ensure good control of the weeds,
 
Topping
Topping is necessary to be done after 35-40 days to
remove the apical shoot to promote more branching,
which boost the flower production and result in higher
yield.
Harvesting and yield
The crop matures in 120-140 days, which is indicated by the yellow
colour developed by the stem and leaves.
Harvesting should always be done in the morning hours to avoid the
trouble caused by the spines on the leaves (in mornings they are
little softer).
Entire plant is pulled and staked for 6-9 days and later threshed and
winnowed. The yield from sole crop can be as high as 15-20 q/ha
(Irrigated) or 10-12 q/ha (un irrigated), if the crop is well
maintained.
Intercrop yield varies from 4-8 q/ha.
