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.

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.
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.
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.
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.
Fertilizer
For one hectare area, application of 80 kg Nitrogen, 30 kg each Phosphorus and Potash and 50 kg of Sulphur is recommended.
Irrigation
Irrigation is given immediately after sowing and subsequent irrigations are given at an interval of 15 days.
Weed control
Weeding is generally done twice.
Pest control
Collar rot caused by Sclerotium rolfsii is observed in some pockets, which is treated by common fungicides.
Harvesting
Harvesting is done in February-March when the flower heads turn brown. The plants are pulled out by the roots.
Post harvest operations
Drying
The harvested plants are dried on mats on the threshing floor till moisture content is low enough for storage.
Threshing
The fruits are separated by carefully rubbing by hands / thrashed and winnowed to separate the clean seeds.
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.
Yield
On an average about 1000 kg dry seed is obtained from an area of one hectare.
