Floral Varieties and Bulb Selection Standards
Rajnigandha varieties are classified into Single (single row of corolla segments) and Double types.
Single varieties (such as Prajwal and Shringar) possess intense fragrance and are predominantly sold as loose flowers for garlands and religious worship.
Double varieties (such as Suvasini and Vaibhav) yield dense multi-petaled spikes highly valued as long-stem cut flowers for florist bouquets.
- Single types (Prajwal, Shringar): Highly fragrant, heavy spike yield, ideal for loose flower marketing and concrete oil extraction
- Double types (Suvasini, Vaibhav): Sturdy long flower stems ideal for premium vase cut flowers and florist arrangements
- Bulb grading: Choose disease-free, spindle-shaped mature bulbs measuring two to three centimeters in diameter
Field Preparation, Spacing, and Planting Practices
Planting is ideally carried out between March and May for year-round flower production.
Tuberose demands well-drained fertile sandy loam soil with high organic carbon and full direct solar exposure.
Bulbs should be treated with approved fungicides before planting on raised ridges to prevent sclerotial stem rot.
- Seed rate: Approximately forty to fifty thousand mature bulbs per acre
- Spacing: Plant bulbs at twenty centimeters by twenty centimeters spacing at a depth of four to five centimeters
- Bulb treatment: Dip bulbs in Carbendazim or Trichoderma slurry for thirty minutes to prevent basal rot
Harvesting, Ratoon Management, and Mandi Marketing
Flowering begins approximately eighty to ninety days after planting, providing continuous harvesting for two to three years as a ratoon crop.
Harvest individual loose florets early in the morning, packing them in ventilated bamboo baskets for immediate wholesale transport.
Growers can track live wholesale flower mandi prices on the KisanPe Mandi Rates portal.
- Loose flower picking: Pluck fully open individual florets early in the morning when moisture turgor is highest
- Cut flower harvest: Cut spikes when bottom one or two florets are opening, using a sharp sterilized knife
- Mandi rates: Check live wholesale flower rates across major regional mandis on the KisanPe Mandi Rates dashboard
