Production Technology
- Propagation: Semi-hardwood stem cuttings (15-20 cm) treated with IBA 3000 ppm; also by layering
- Spacing: 1.5 x 1.5 m (J. sambac); 2 x 2 m (J. grandiflorum)
- Planting time: June-July (onset of monsoon)
- Pruning: Annual pruning in November-December to 30-40 cm height; promotes profuse spring flowering
- Fertilizers: N:P:K at 120:240:120 g/plant/year + 10 kg FYM/plant
- Irrigation: Weekly during summer; drip irrigation preferred
Harvesting and Yield
- Harvest unopened buds in the early morning (4-6 AM)
- J. sambac: 8-10 tonnes/ha/year (12 months of harvest)
- J. auriculatum: 6-8 tonnes/ha/year (April-September harvest)
- J. grandiflorum: 5-7 tonnes/ha/year
- Concrete and absolute extracted for perfumery industry (Rs. 3-5 lakh/kg for jasmine absolute)
Summary Cheat Sheet
| Crop | Key Point |
|---|---|
| Jasmine | High-value fragrant crop; species-wise spacing and pruning are critical |
| Crossandra | Loose flower crop suited to warm humid regions with good drainage |
| Harvest window | Early morning harvest preserves freshness and market value |
| Value addition | Strong linkage to garland trade and fragrance industry |
