II. Biological Characteristics
- Roots & Stem: Fibrous root system, shallow, mainly in topsoil. Annual herb, 15-20cm tall or more depending on growth stage.
- Leaves & Flowers: Leaves near base arranged closely, serrated edges, tough, elongated, dark green. Flowers greenish-white, spherical fruit, small brownish-black seeds.
- Climate: Prefers temperate, cool climate, cold-tolerant. Moisture-loving but intolerant of waterlogging.
- Light: Prefers diffused light; direct sunlight hinders growth and reduces yield. Therefore, shading is necessary for production.
- Soil: Grows well in soil rich in organic matter, light, loose, neutral pH.
III. Cultivation Techniques
1. Season
- Best time: January - February. Can be grown year-round in temperate climates.
- Southern Region: Start sowing at end of rainy season (November to following February).
2. Soil & Fertilizers
Soil Prep: Plow thoroughly, clear weeds. Raise beds 1.1 - 1.5m wide depending on season.
Fertilizer for 1,000m²:
- Decomposed Manure: 1.0 - 1.5 tons
- Superphosphate: 25 - 30kg
- Potassium Chloride: 15 - 20kg
- NPK: 30 - 40kg
* Basal application: All manure, 1/3 NPK, 100% phosphate, 1/3 potassium mixed into bed surface 15-20 days before sowing.
3. Sowing & Care
- Sowing: 1.2 - 1.5kg seeds/1000m². Soak in warm water 35-40°C (10-12h) -> Wash -> Mix with fine soil -> Broadcast. Cover with thin soil and straw/mulch.
- Shading: Use black mesh or bamboo screens 1.8-2.0m high. Must shade year-round.
- Care:
- Water to keep moist (flood or furrow irrigation every 10 days). Drain if heavy rain.
- Weed regularly by hand.
- Top dressing: 1st time (2-3 true leaves) with 6-8kg NPK or Urea 1-2%. 2nd time 12-15 days later. Apply Potassium when growing strongly. - Pests: Few pests. Use biological control and integrated pest management.
IV. Harvest & Seed Production
- Harvest: 35-40 days after planting (5-6 leaves). Harvest mature leaves, leaving 3 old leaves and 1 young leaf at tip. Bundle 5-7 leaves.
- Yield: Harvest 12-13 times/year (about 8 months). In South, often harvest whole plant then resow.
- Seed Production: Stop harvesting leaves in October for flowering. Harvest seeds in December, dry whole plant, collect and store seeds.
