About Lesson
Botanical Information
- Botanical Name: Cinnamomum verum, Cinnamomum zeylanicum
- Family: Lauraceae
- Common Names: Cinnamon
- Origin: Sri Lanka and the Malabar Coast of India
- Plant Part Used: Bark and Leaves
Uses
- Bark: The bark of cinnamon is the primary commercial product, used in spice and medicinal applications.
- Leaves: The leaves of cinnamon yield an essential oil, the main constituent of which is Eugenol, giving it a strong fragrance. The oil is used for flavoring, aromatherapy, and medicinal purposes.
- Oil: The oil extracted from the leaves has antiseptic, antibacterial, and anti-inflammatory properties, often used in perfumes, soaps, and cosmetics.
Soil and Climate Requirements
- Soil Requirements:
- Cinnamon thrives in well-drained, sandy loam soils that are rich in organic matter and humus content.
- Red, dark brown soils that are free from rock or gravel are ideal for cinnamon cultivation.
- Soil pH should ideally range from 5.5 to 6.5.
- Climate Requirements:
- Cinnamon requires a hot, humid climate to grow well.
- The plant thrives at an average temperature of 27°C.
- Annual rainfall of about 2000–3000 mm is favorable for cinnamon growth.
Varieties of Cinnamon
- Navashree: High and stable regeneration capacity (6-7 shoots/year). High yield.
- Nithyashree: Another high-yielding variety, suitable for cultivation in Indian conditions.
- Konkan Tej:Released by BSKVV Dapoli in 1992. Known for high volatile oil content in the bark (3.2%).
- Sweet Cinnamon: Known for its sweet aroma and flavor.
- Honey Cinnamon: A variety with a unique flavor profile.
Propagation Methods
- Seed Propagation:
- Cinnamon is propagated by seed. The seeds are extracted from ripe fruits, washed free of pulp, and sown in sand beds or polythene bags.
- Seeds germinate in 10–20 days, but they have low viability, so they must be planted soon after extraction.
- Cuttings: Semi-hardwood cuttings from mature plants can be used for propagation.
- Air Layering: Air layering is another common method for vegetative propagation, where branches are encouraged to root while still attached to the parent plant.
Planting and Spacing
- Planting Time: Cinnamon is typically planted during June–July, coinciding with the monsoon season for proper seedling establishment.
- Planting Method: Pits of 50 cm depth are dug, spaced at 3 m x 3 m. Each pit is filled with compost and topsoil before planting. One-year-old seedlings are transplanted into these pits.
- Shade Requirement: The plants benefit from partial shade during the initial years for healthy and rapid growth.
Manuring and Fertilization
- First Year: Apply 20 g of Nitrogen (N), 18 g of Phosphorus (P₂O₅), and 25 g of Potassium (K₂O) per seedling.
- After Three Years:
- Apply 30 kg of FYM (Farm Yard Manure), 4 kg of neem cake, 150 g of Nitrogen, 75 g of Phosphorus, and 150 g of Potassium per plant.
- Fertilizers are applied in two doses: once in September and again in March.
Training and Pruning
- Coppicing: When the seedlings reach 2-3 years old, the shoot is cut back to about 30 cm from the ground to encourage the growth of side shoots. This practice is called coppicing.
- Pruning: Prune dead, diseased, or overgrown shoots to maintain a healthy plant structure.
Harvesting
- Harvesting Time:
- Cinnamon is harvested 2-3 years after planting.
- The ideal harvesting period for cinnamon bark is from September to November.
- Harvesting Method:
- The stems with a diameter of 2–3 cm and length of 1–1.25 m are cut close to the ground.
- A “test cut” is made on the stem to check if the bark separates easily, signaling the right time for harvesting.
- Peeling the Bark:
- Peeling is done with a small, round-edged knife. It should be done on the same day the stems are cut.
- After peeling, the stems are earthened up with soil to promote the growth of new shoots.
Post-Harvest Handling
- Drying and Packaging:
- The harvested bark is dried, cleaned, and bundled together for storage.
- It should be carefully processed to maintain its quality, and the bark is made into quills.
- Oil Extraction:
- Leaves yield oil, which is extracted through steam distillation. The yield of oil is about 1 to 1.25 kg of oil per ton of leaves.
Yield
- 3–4 Years After Planting: The yield of quills ranges from 62 to 125 kg per hectare.
- 10–11 Years After Planting: The yield increases to 225 to 300 kg of quills per hectare.
- Leaves: 1 ton of leaves per hectare yields approximately 1 to 1.25 kg of oil per year.
