Tuberose, known in India as Rajnigandha, is a popular flower crop valued for its strong fragrance, beautiful white blooms, and high demand in the market. It is used in garland making, bouquets, essential oil extraction, and decorative purposes. Because of its steady demand and good earning potential, many farmers are now growing tuberose as a commercial crop. Cultivating tuberose is not very difficult, but it requires proper planning and timely field operations for best results.
Climate and Soil
Tuberose grows well in warm, humid climates. It can be planted almost throughout the year in many parts of India, but the best planting seasons are February–March and August–September. The crop prefers full sunlight, which helps in good flowering. For soil, well-drained sandy loam or loam soil with good organic matter is ideal. Waterlogging must be avoided because it can damage the bulbs.
Land Preparation
Before planting, the land should be ploughed 2–3 times to make it loose and friable. Adding 10–12 tonnes of well-decomposed farmyard manure (FYM) per acre improves soil fertility and helps in root growth. Beds or ridges should be prepared to ensure proper drainage.
Planting Material and Spacing
Tuberose is grown from bulbs. Farmers should select healthy, disease-free bulbs of about 1.5–2.0 cm diameter for good flowering. Bulbs should be dipped in a fungicide solution before planting to avoid rot.
The recommended spacing is 30 cm between rows and 20–25 cm between bulbs. Planting depth should be around 3–5 cm. After planting, light irrigation should be given to help bulbs sprout.
Irrigation
Tuberose requires regular moisture but cannot tolerate standing water. Irrigation should be given once every 6–7 days in summer and once every 10–12 days in winter. Drip irrigation works very well for tuberose because it saves water and reduces disease risk.
Fertilizer Application
Tuberose responds well to fertilizers. Farmers can apply:
Nitrogen (N): 40–50 kg per acre
Phosphorus (P₂O₅): 30–40 kg per acre
Potassium (K₂O): 30–40 kg per acre
Half of the phosphorus and potassium should be applied at planting. Nitrogen should be given in 2–3 split doses at monthly intervals to encourage continuous flowering.
Weed and Pest Management
Weed control is essential, especially during the first two months. Farmers can do hand weeding or use mulching to reduce weed growth. Common pests include thrips, aphids, and mites, which suck sap from leaves and flowers. Regular monitoring helps in early detection. A recommended insecticide spray can be used when pest levels increase.
Flowering and Harvesting
Tuberose starts flowering 45–60 days after planting and continues for several months. Flowers are harvested early in the morning or late evening when they are fresh. Spikes used for bouquets are harvested when the lower 1–2 flowers have opened.
Conclusion
With proper planting, timely fertilizer application, good irrigation, and pest management, tuberose cultivation can give excellent returns. It is a reliable and profitable flower crop that offers continuous income through its long flowering period.
