Cultivation of Ajwain (Carom Seeds)

Carom seeds, also known as Ajwain, are an important medicinal plant. They are counted among the major spices as well. Ajwain is cultivated both for its leaves and seeds. The oil extracted from its seeds is used to prepare various medicines. It is used in the treatment of several ailments such as indigestion, stomach pain, and colds. Due to its constant demand, cultivating Ajwain can be profitable for farmers. In this post, we will go through the important details of Ajwain cultivation, from sowing to harvesting.
How to Cultivate Ajwain?
Suitable Time for Cultivation
- In Northern Indian regions, Ajwain cultivation is typically done between September and October. During this season, the weather remains relatively cool, which is favorable for seed germination and plant growth. However, extreme cold and frost should be avoided as they can damage the crop. In some regions, it is also sown between July and August.
Ideal Climate
- Ajwain thrives in moderately dry and warm climates. It grows well in temperatures around 15-17°C. Generally, tropical and subtropical regions are well-suited for Ajwain cultivation.
Suitable Soil
- Well-drained loamy soil rich in organic matter is ideal for Ajwain cultivation. Additionally, light sandy loam and deep fertile soils can also support successful cultivation. The soil pH should range between 6.5 and 8.5. Soils rich in organic matter tend to yield better crops.
Best Varieties
- The yield of ajwain also depends on its varieties. For a good harvest, you can choose from varieties like Gujarat Ajwain-1, Ajmer Ajwain-1, Ajmer Ajwain-2, Pratap Ajwain-1, and others.
Field Preparation Method
- Preparing the field is crucial for cultivating ajwain. First, perform deep plowing of the field to make the soil loose and crumbly, providing enough space for the roots to grow. After this, conduct 2-3 light plowings and level the soil using a plank to make the field smooth.
Seed Quantity
- For cultivation on one acre of land, 1 to 2 kilograms of seeds are required. When selecting seeds, ensure they are free from any diseases. Choose healthy seeds and treat them before sowing.
Sowing Method
- Ajwain seeds are sown in rows. Maintain a distance of 12 inches between the rows and 8-12 inches between the plants. Avoid sowing the seeds too deep, as this can make germination difficult.
Irrigation Management
- Proper drainage is essential for ajwain (carom seed) crops. The first irrigation is done immediately after sowing. Subsequent irrigations are done based on the weather and soil conditions. Ajwain does not require frequent irrigation, but it is important to maintain moisture in the soil.
Weed Control
- Special attention should be given to weed control in ajwain cultivation. If weeds become a problem in the field, plant growth can be affected, leading to reduced yield and quality. In smaller areas, weeding should be done 20-25 days after germination. In larger areas, tools like hoes or small agricultural equipment can be used for weeding. If the weed problem is severe, the appropriate amount of chemical herbicides can be used.
Pest and Disease Control
- Ajwain crops are commonly affected by blight, stem rot, and aphids. Regular monitoring of the crop is essential to prevent these diseases and pests. This allows for early control. Use chemical treatments as recommended by agricultural experts to manage these diseases and pests.
Harvesting the Crop
- Ajwain takes around 140 to 150 days to mature. Harvesting should be done when the plant's leaves and stems turn yellow and the seeds change from green to brown. After harvesting, allow the plants to dry in the sun for a few days. Once the plants are fully dried, the seeds can be separated through threshing.
