Introduction
Galangal (commonly called Thai ginger, Lengkuas, or Kulanjan) is one of the most important rhizome spices in global cuisines and herbal medicine. It belongs to the Zingiberaceae family, the same group as ginger and turmeric, but has a distinct, sharp, citrusy flavor that makes it a premium ingredient.
Galangal is widely used in Thai, Indonesian, Malaysian, Vietnamese, and Indian cuisines, particularly in soups, seafood, curries, broths, and herbal pastes. It is also a key ingredient in herbal medicine, essential oils, and Asian nutraceutical industries.
Due to its rising demand in international food chains, natural health supplements, and organic spice markets, galangal farming has become a highly profitable cultivation opportunity. It thrives in tropical and subtropical climates and can be grown commercially with moderate investment.

- Farming Guide
Soil Requirements
Galangal grows best in rich, humus-filled soil with high organic content.
Soil type: Loamy, sandy loam, or red soil
Soil pH: 5.5 to 7.0
Good drainage is essential
Heavy clay soils should be avoided unless amended with organic matter
Climate Conditions
Ideal temperature: 20°C to 32°C
Rainfall requirement: 1500–3000 mm annually
Grows well in warm, humid regions
Cannot withstand frost or severe cold
Partial shade improves rhizome quality but excessive shade reduces yield
Land Preparation
Deep ploughing to prepare a friable soil bed
Apply 10–12 tons of compost or FYM per acre
Raised beds recommended in areas with high rainfall
Soil solarization for 2–3 weeks helps reduce soil pathogens
Galangal Planting Material
Propagated through rhizomes (not seeds)
Healthy rhizome fingers of 30–40 grams are used
Ensure disease-free and fresh propagating material
Planting Season
Best time: April to June (monsoon onset)
In tropical countries, can be planted year-round with irrigation
Spacing and Planting Method
Spacing: 45 cm × 30 cm or 60 cm × 45 cm
Depth: 4–6 cm beneath soil
Method:
Place rhizomes with buds facing upward
Cover lightly with soil
Add mulching material (dry leaves, straw) to conserve moisture
Irrigation Management
Requires regular moisture but not waterlogging
First irrigation immediately after planting
Irrigate every 7–10 days in dry season
Drip irrigation improves rhizome size and reduces disease
Nutrient and Fertilizer Requirements
Per acre nutrient schedule:
FYM/organic manure: 10–12 tons
NPK: 40:30:40 kg
Neem cake: 200–250 kg
Vermicompost (optional): 1–2 tons
Apply nitrogen in split doses during active growth
Weed and Crop Management
First weeding after 30–40 days
Subsequent weeding every 45–60 days
Mulching helps reduce weed growth and supports rhizome development
Earthing-up improves soil aeration
Pest and Disease Management
Galangal is relatively hardy, but may face:
Rhizome rot (due to waterlogging)
Leaf spot
Shoot borer
Control measures:
Use well-drained soil
Apply Trichoderma in pits
Spray organic neem-based solutions
Maintain proper spacing
Crop Duration and Harvesting
Crop duration: 8 to 10 months
Rhizomes are harvested when plants start yellowing
Harvest manually or with light mechanical tools
Average yield: 8–12 tons fresh rhizomes per acre
Dried rhizome output is 20–25 percent of fresh weight
After harvesting, rhizomes are washed, cured, and dried or processed depending on market demand.
