1.0 Product and its applications
Ajamoda (Trachyspermum
ammi Linn. Sprague) is much used as a medical plant in Ayurvedic
& Unani medicine. It is called in English as Bishop's
Weed, Carum, Ajwan, Lovage; in Sanskrit as Yavani, Yavana,
Yavanaka, Ajamoda, Ajamodika; in Hindi as Ajowanj, Ajwain;
in Tamil as Omum; in Telugu as Omamu and in Kannada as Omu,
Ajamoda.
English 'Ajwan' is just the Romanized
spelling of the Hindi name ajvan. Most European languages
have similar names, although the spelling is sometimes varied,
e.g., in Dutch ajowan or German Adiowan. Hindi name can be
traced back to Sanskrit yavanaka, which is derived from the
adjective yavana Greek. Modern Northern and Southern Indian
names like Gujarati yavano, Bengali jowan, Punjabi aijavain
and Tamil omum have the same source. This suggests that the
spice originated from the Eastern Mediterranean and arrived
in India in course of the Greek conquest of Central Asia.
The Sanskrit term yavana for Greece belongs to the same kin
as Arabic al-Yunan. Another group of names for ajmoda is derived
from Sanskrit ajamoda or ajamodika. Examples in modern Indian
languages include Kannada ajamoda and Sinhala asamodagam.
Ajamoda is much valued for its antispasmodic, stimulant, tonic
and carminative properties. It is administered in flatulence,
atonic dyspepsia and diarrhoea, and often recommended for
cholera. In the Unani system, ajmoda is used as a crude drug
to enhance the body's resistance and is prescribed in amoebiasis.
It is a potent antimicrobial agent.
Ajamoda is useful against diseases of the digestive tract
and fever. Where unclean tap water can result in arbitrary
complications, ajmoda often comes to the traveler's rescue.
Just chew on spoonful of the fruits for a few minutes and
wash down with hot water. In the West, thymol is used in medicines
against cough and throat irritation.
It is also a popular kitchen spice in India. The strong aroma
is enhanced by toasting or frying and goes well with potatoes
or fish. Legumes are, however, the most important fields of
application. In India where these dishes are popular since
they provide a source of protein to the many vegetarians,
they are commonly flavored with hot butter or edible oil frequently
containing ajmoda. This seemingly simple preparation is much
more sophisticated than sheer heat treatment, since most aroma
compounds in spices are lipophilic and dissolve much better
in fat than in water. Thus, frying in fat not only enhances
the fragrance because of the high temperature, but also extracts
the flavor to the fat, whence it can be dispersed throughout
the food efficiently. Outside the Indian subcontinent, Ajmoda
enjoys popularity in the Arabic world.
Ajmoda seeds are employed along with other spices and condiments
in making pickles, confectionery and beverages. It is a good
remedy for indigestion. A paste of the crushed fruit is applied
externally for relieving colic pains. It is also used in lotions
and ointments.
The seed oil is a major source of
thymol, being present to the extent of 35-60%. Ajmoda oil
is aromatic, stimulant and carminative. It possesses antimicrobial
activity. The essential oil (2.5 to 5% in the dried fruits)
is dominated by thymol (2-isopropyl-5-methylphenol, 35 to
60%); furthermore, ?-pinene, p-cymene, limonene and ?-terpinene
have been found.
2.0 Market Potential
Exporters, buyers, processors, traditional
practitioners, Ayurvedic, Unani and Siddha drug manufacturers
throng the markets for procurement of this plant every year.
Its domestic as well as export demands are quite large.
3.0 Basis and Presumption
a) The agricultural land and related infrastructure
is available with the entrepreneur.
b) Prices are calculated as per the prevailing market rates.
c) The yields depend on proper implementation of package of
practices.
d) Economics of cultivation greatly improves on scale of operation.
e) This activity provides tax-free high returns. Additionally
a number of government support schemes are available. Latest
provisions need to be checked up.
f) Market for medicinal plants is volatile and economics may
vary from time to time.
4.0 Agri practices
It is cultivated
in most parts of India. The plant is believed to have originated
in Egypt. Although it is grown around the Mediterranean region
and in South-West Asian countries such as Iraq, Iran, Afghanistan
and Pakistan, ajmoda is chiefly produced in India. It is grown
throughout the country, mainly in plains, but flourishes equally
well at higher altitudes in the plateaus and the hills. It
is produced in Madhya Pradesh, Uttar Pradesh, Rajasthan, Gujarat,
Maharashtra, Andhra Pradesh, Karnataka, Bihar and West Bengal.
Ajmoda is an erect, glabrous or
minutely pubescent a profusely branched winter annual herb.
The stems are striated; the leaves are rather distant, 2-3-pinnately
divided, the segments linear. The flowers occur in terminal
or seemingly-lateral pedunculate, compound umbels, white and
small. The fruits are ovoid, muricate, aromatic cremocarps,
greyish brown. The mericarps, which are the components of
the fruit, are compressed, with distinct ridges and tubercular
surface.
4.1 Soil & Climate
It is mainly grown as a winter crop in
subtropical and temperate climate and as summer crop in temperate
climates. It grows on any soil type but performs best in humus
rich loamy soil. It is grown as a rain fed crop in heavy soils
whereas it requires irrigation in light textured soils. It
is basically a sun loving plant.
4.2 Land Preparation
The soil is reduced to a fine tilth by
ploughing or digging repeatedly during September - October.
The field is also weeded and heavily manured by FYM.
4.3 Propagation
It is generally propagated by seeds. Seeds
are broadcast or drilled in rows 45 cm apart in November.
Seed dose is 2.3-3.5 kg/ha. Irrigation is given immediately
after sowing and later at 7-10 days interval. The seeds germinate
in 7-14 days. Broadcast crop may be thinned to a spacing of
30-45 cm. N, P2O5, K2O and S are applied at 80,30,30,50 kg/ha,
respectively for obtaining best yields. Flowering starts in
2 months time.
4.4 Fertilizer
For one hectare area, application of 80
kg Nitrogen, 30 kg each Phosphorus and Potash and 50 kg of
Sulphur is recommended.
4.5 Irrigation
Irrigation is given immediately after
sowing and subsequent irrigations are given at an interval
of 15 days.
4.6 Weed control
Weeding is generally done twice.
4.7 Pest control
Collar rot caused by Sclerotium rolfsii
is observed in some pockets, which is treated by common fungicides.
4.8 Harvesting
Harvesting is done in February-March when
the flower heads turn brown. The plants are pulled out by
the roots.
5.0 Post harvest
operations
5.1 Drying
The harvested plants are dried on mats
on the threshing floor till moisture content is low enough
for storage.
5.2 Threshing
The fruits are separated by carefully rubbing by hands / thrashed
and winnowed to separate the clean seeds.
5.3 Oil distillation
The dried seeds are crushed and distilled to obtain the essential
oil. Hydro or steam distillation is resorted to. Seeds lose
the essential oil when stored for long time. On an average,
the dry seeds contain 2-4% oil.
6.0 Yield
On an average about 1000 kg dry seed is
obtained from an area of one hectare.
7.0 Economics of cultivation per hectare
