A. Suitable time to plant cardamom in the land:

If the height of the cardamom plant is less than one foot, it should be planted in the ground. Cardamom should be planted in the land during monsoon. However, in India it can be planted in July. Because during this time the need for irrigation is less due to rainfall. Remember that cardamom plants should always be planted in the shade. Its growth is reduced due to excessive sunlight and heat. While planting cardamom trees in pits or beds, the distance from one tree to another should be kept at 60 cm.

b. Soil and Climate for Cardamom Cultivation:
Red loam soil is considered good for cardamom cultivation. Apart from this, other types of soil can be easily cultivated using fertilizers. For its cultivation, soil pH should be 5 to 7.5. On the other hand, tropical climates are considered best for cardamom cultivation. Cardamom requires a temperature of 10° to 35°C for cultivation.

c. How to grow cardamom:
Before cultivating cardamom, it is necessary to prepare the field for it. For this, the field must be plowed and leveled first. So that rain water does not come out from the field during monsoon. Before planting cardamom, the field should be plowed once with a rotavator.

1. Planting cardamom seedlings:
If you want to plant cardamom seedlings in the field, you need to make beds at a distance of one to two feet. At the same time, to plant cardamom in the hole, the seedlings should be planted at a distance of 2 to 3 feet. Dung manure should be mixed well in the dug hole.

2. How to grow cardamom tree in nursery:
Cardamom seedlings are prepared in the nursery before planting in the field. For this, cardamom seeds should be sown in the nursery at a distance of 10 cm. For this, one kg of cardamom seeds is enough to make a nursery in one hectare. When the cardamom seeds start sprouting, you cover the sprouts with dry grass.

3. Irrigation System in Cardamom Cultivation:
If the seedlings are planted in the field during monsoon, it requires less irrigation. Cardamom plants should be first irrigated immediately after planting if rainfall is low. After that, irrigation should be done as needed. At the same time, adequate irrigation should be provided during the summer season. Care should be taken during irrigation so that the field is not filled with water more than necessary. Therefore, proper arrangements for water drainage should be made on the land. On the other hand, irrigation should be continued every 10 to 15 days to maintain the required moisture in the soil.

4. Use of fertilizers in cardamom cultivation:
Before planting cardamom trees in the land, each tree should be placed in a pit with 10 kg of old cow dung and 1 kg of vermicompost. Apart from this, neem pitha and chicken manure should be applied to this tree two to three times a year. Due to which the plant develops well.

5. Take these measures to control weeds:
Like other crops, weeds grow in the field during cultivation of cardamom. It should be removed from time to time. For this, the field should be weeded from time to time. Weeding of the field keeps the field moist and thus the cardamom plant grows faster.

6. Control of insects and diseases in cardamom cultivation:
Incidentally, cardamom crops are less prone to pests and diseases. But many times it shows symptoms of powdery mildew and fungal diseases. In this disease, the leaves of the plant shrivel and die. Cardamom seeds should be treated with medicine called Trichoderma before sowing in the nursery to control this disease. If a disease occurs on any plant, it should be immediately removed from the field to prevent the disease from spreading to other plants.

7. Incidence of whitefly disease and its control in cardamom cultivation
Cardamom is also prone to whitefly disease. If affected by this disease, the growth of cardamom plant stops. Whiteflies mostly attack cardamom leaves and destroy the plant by sucking the sap. To prevent white fly disease, mix caustic soda and neem water well and spray on the leaves.

8. When to collect cardamom:
Collecting seeds from cardamom plants should be done a little before the seeds are fully ripe. Cardamom loses its quality when overripe. Clean the seeds thoroughly after harvesting. After that, dry the seeds thoroughly to remove any excess moisture. Once the seeds are completely dried and ready, take them to the market for sale.

d. What is the yield of cardamom?
With improved technology and proper cultivation, the yield of cardamom is 135 to 150 kg of cardamom per hectare after proper drying.

e. Price of cardamom:
The price of cardamom in the market is twelve to two thousand taka per kg. Its price fluctuates according to market demand.
