Caraway

Carum carvi

1. Identification and origin

Carum carvi L. is a biennial herbaceous species of the Apiaceae family, known as caraway or meadow cumin. It is native to Europe, North Africa and Western Asia, and is currently cultivated in temperate regions all over the world. The aromatic seeds are used as a spice, and the plant also has medicinal and industrial applications.

2. Economic importance

Caraway is valued for its seeds rich in essential oils, widely used in the food industry (bread, cheeses, beverages, condiments), pharmaceutical and cosmetic industries. The crop has growing importance in production systems of aromatic and medicinal plants, due to the high commercial value of the seeds and the interest of the natural extracts industry.

3. Botanical characterisation

Biennial herbaceous plant, with a basal rosette in the first year and an erect flowering stem in the second. The leaves are finely divided, of intense green colouration. The flowers are small, white or pinkish, grouped in compound umbels. The fruits (mericarps) are elongated, aromatic and constitute the marketed part. Reproduction is by seed.

4. Soil and climate requirements

It prefers temperate climates, with moderate temperatures and good luminosity. It tolerates cold in the first year, but late frosts can affect flowering. It requires well‑drained, fertile soils, with a medium texture and pH between 6.0–7.5. The crop needs regular moisture, but is sensitive to waterlogging, which favours root diseases.

5. Main pests

• Aphids (Aphididae): cause deformations and may transmit viral diseases.
• Carrot fly: Psila rosae causes damage to the young roots.
• Lepidopteran caterpillars: partial defoliation in early stages.
• Mites (Tetranychidae): silvering and reduction of the photosynthetic area.
• Nematodes: Meloidogyne spp. may affect root development.

6. Main diseases

• Powdery mildew: Erysiphe heraclei causes white mycelium on leaves.
• Alternaria blight: Alternaria spp. causes leaf spots and necrosis.
• Root rots: Pythium and Phytophthora associated with waterlogged soils.
• Bacterial blight: caused by opportunistic bacteria in conditions of high humidity.
• Damping‑off: caused by soil fungi in seedlings.

7. General cultural management

It includes the use of seedlings or direct sowing in well‑prepared soils, weed control, moderate irrigation and monitoring of pests and diseases. Crop rotation is essential to reduce soil problems. The harvesting of the seeds should be carried out when the fruits begin to darken, avoiding losses by dehiscence. Adequate drying is fundamental to preserve the essential oil content.
