Turmeric can be grown in a variety of climates, but it thrives best in warm, humid conditions with an average temperature of 20-30°C. It requires a well-drained, sandy loam soil with a pH of 6.5-7.5.
Land preparation
The land should be prepared by plowing and harrowing to create a fine tilth. It is essential to remove all weeds and debris before planting.
Planting
Turmeric is planted from rhizomes, which are the underground stems of the plant. The rhizomes should be selected from healthy, disease-free plants. They should be treated with a fungicide before planting to prevent diseases.
Rhizomes are planted in furrows or ridges that are spaced 45-60 cm apart. The rhizomes are planted 5-7 cm deep and 25-30 cm apart within the row.
Irrigation
Turmeric requires regular irrigation, especially during the early stages of growth. The soil should be kept moist but not waterlogged.
Fertilization
Turmeric requires a balanced fertilizer application. A good fertilizer mix for turmeric is NPK 125:37:37 kg/ha. The fertilizer should be applied in three splits: one-third at planting, one-third at 60 days after planting, and the remaining one-third at 120 days after planting.
Weed control
Weeding is important in turmeric cultivation to prevent competition for water and nutrients. Weeding should be done at least three times during the growing season.
Pests and diseases
Turmeric is susceptible to a number of pests and diseases, including rhizome rot, leaf spot, and nematodes. It is important to monitor the crop regularly and take preventive measures to control pests and diseases.
Harvesting
Turmeric is harvested 8-10 months after planting. The rhizomes are dug up and then cleaned and dried.

Additional notes
- Turmeric can be intercropped with other crops, such as coconut and areca nut.
- Turmeric can also be grown in pots and containers.

Turmeric is a long-duration crop, and it can be intercropped with a variety of short-duration crops to increase the overall yield from the land.
Some of the most popular intercrops for turmeric in India include:
- Legumes: Legumes, such as cowpea, black gram, and green gram, are a good choice for intercropping with turmeric because they fix nitrogen in the soil. This can help to improve the fertility of the soil and increase the yield of turmeric.
- Oilseeds: Oilseeds, such as sesame and groundnut, are also a good choice for intercropping with turmeric. They have different root systems than turmeric, so they do not compete with each other for water and nutrients.
- Vegetables: Vegetables, such as okra, eggplant, and tomato, can also be intercropped with turmeric. However, it is important to choose vegetables that have a short growing season, so that they do not interfere with the growth of the turmeric crop.
When intercropping turmeric with other crops, it is important to choose crops that have different growth habits and root systems. This will help to avoid competition between the crops for water and nutrients. It is also important to plant the crops at the right time so that they do not interfere with each other's growth.
Here are some tips for successful intercropping with turmeric in India:
- Select crops that have different growth habits and root systems.
- Plant the crops at the right time, so they do not interfere with each other's growth.
- Manage the crops carefully to ensure that they both get enough water and nutrients.
- Monitor the crops for pests and diseases and take preventive measures to control them.
Intercropping can be a very effective way to increase the productivity and profitability of turmeric cultivation in India. By following the tips above, farmers can successfully intercrop turmeric with other crops to maximize their yields and income.
