This presentation outlines the cultivation practices of tuberose, a significant ornamental plant known for its fragrance and economic value in the cut flower and essential oil industries. It covers the propagation methods, environmental requirements, and post-harvest management techniques essential for successful cultivation. The information provided is crucial for enhancing yield and ensuring high-quality flower production.
Introduction to Tuberose
Tuberose (Polianthes tuberosa L.) belongs to the Amaryllidaceae family and is recognized for its fragrant spikes, which can reach lengths of 30 to 45 cm. The single-flowered varieties are more aromatic than the double types, containing 0.08 to 0.14 percent concrete used in high-grade perfumes. The flowers are versatile, used for essential oil extraction, garlands, and as cut flowers for decoration.
Economic Importance
Tuberose holds a special position among ornamental bulbous plants due to its beauty, elegance, and sweet fragrance. It has significant economic potential in the cut flower trade and essential oil industry, leading to its widespread cultivation in tropical and subtropical regions worldwide.
Origin and Distribution
Natively from Mexico, tuberose spread globally in the 16th century. The Aztecs cultivated it over 600 years ago, and it was introduced to Europe by Spanish explorers. It became popular in Victorian gardens, known for their fragrant white flowers that bloom at night.
Types and Cultivars of Tuberose
There are three main types of tuberose: single (one row of corolla segments), semi-double (2-3 rows), and double (more than three rows). Notable cultivars include:
Cultivar
Characteristics
Rajat Rekha
Single flowered with silvery white streaks.
Shringar
Single flowered, pinkish tinge, ideal for garlands, yielding about 15,000 kg/ha/yr.
Cultivation Techniques
Select a sunny location for planting.
Prepare the soil to a depth of 5 cm.
Water generously after planting, then moderately during the growing season.
Apply a balanced fertilizer and prune to encourage growth.
Harvest bulbs in spring and store them properly.
Required Environment
Climate: Tuberose prefers a mild climate with temperatures ranging from 20°C to 35°C. Extreme temperatures can affect flower quality.
Soil: It thrives in well-drained loam or sandy loam soils with a pH of 6.5 to 7.5, rich in organic matter.
Propagation Methods
Propagation is primarily through bulbs. Dormancy can be broken using a 4% Thiourea solution. Suitable bulbs are spindle-shaped, disease-free, and 1.5 to 3.0 cm in diameter.
General Cultivation Process
Choose a sunny site for optimal growth.
Prepare the soil thoroughly to avoid clods.
Select bulbs with a diameter of 2.0-3.0 cm for planting.
Implement effective weed control measures.
Apply fertilizers based on soil type and climatic conditions.
Nutrient Management
Essential nutrients include nitrogen, phosphorus, and potassium. Deficiencies can lead to reduced flowering and plant vigor. Common diseases include stem rot and leaf spot, while pests like grasshoppers and thrips can damage crops.
Harvesting Techniques
Harvest tuberose by cutting spikes at the base during cool hours. For vases, cut when the first flowers open. Proper timing is crucial to minimize weight loss during transport.
Post-Harvest Management
To prolong vase life, immerse cut spikes in water immediately after harvest. Use a holding solution of 2% sucrose and 300 ppm Al2(SO4)3. Proper grading and packaging are essential for maintaining quality during transport.
Yield and Economic Benefits
Flower yields range from 14-15 t/ha, with concrete yields of 8-10 kg/ha. Tuberose cultivation can enhance biodiversity and provide economic benefits through flower sales.

Land Preparation and Planting
Initial ploughing is required to remove weeds, followed by digging pits of size 30 cu. m. Each pit should have 10 kg of Farm Yard Manure (FYM) before planting rooted cuttings.
Irrigation
Irrigation should be done immediately after planting and then every 7-10 days depending on weather and soil conditions.
Manuring
Each plant should receive 10 kg of FYM, 60 g of Nitrogen, and 120 g each of Phosphorus and Potassium in two split doses.
Inter-Cultural Operations
Weeding and strengthening irrigation channels are essential. The first weeding should occur 20-25 days after planting.
Pruning
Pruning is done to shape the plant and improve yield. It is advisable to prune during the last week of November.
Plant Protection
Major pests include bud worm and red spider mite. Control measures include spraying monocrotophos and sulfur. Root rot and nematode infestation are common diseases.
Season of Flowering and Harvesting
Flowering begins six months after planting, with buds picked in the early morning before sunrise.
Yield
Commercial yields can reach 3500 kg per acre after four years, with the economic life of the plant estimated at 15 years.
Conclusion
Jasmine is an attractive flower with significant socio-cultural value and economic potential, making its cultivation profitable.
