🌸 Gladiolus, Tuberose, and Lily — Production Technology
Gladiolus, Tuberose, and Lily — Production Technology.
Gladiolus, tuberose, and lily are high-value bulbous floriculture crops where planting material quality, climate control, and correct harvest stage directly determine market grade and vase life.
Gladiolus (Gladiolus spp.)
Introduction
Gladiolus, known as the "Sword Lily", belongs to the family Iridaceae. It is one of the most important bulbous cut flower crops, valued for its tall flower spikes with multiple florets.
Varieties
- Red: American Beauty, Oscar, Red Majesty
- Pink: Pink Friendship, Priscilla, Rose Supreme
- White: White Prosperity, Snow Princess, White Friendship
- Yellow: Gold, Nova Lux, Jester Gold
- Bicolour: Peter Pears, Suchitra, Arka Kesar
Production Technology
- Propagation: Through corms (modified underground stems) and cormels
- Corm size: Large corms (>5 cm diameter) produce best quality spikes
- Planting depth: 5-7 cm in light soils; 3-5 cm in heavy soils
- Spacing: 20 x 20 cm or 30 x 20 cm
- Season: Plant from September to February for winter-spring flowering
- Soil: Well-drained sandy loam, pH 5.5-6.5
- Fertilizers: N:P:K at 200:200:200 kg/ha; half N at planting, half at 4-leaf stage
- Staking required to prevent lodging of tall spikes
Harvesting
- Harvest when 2-3 lower florets show colour
- Cut spikes in the early morning with a sharp knife
- Leave at least 4 leaves on the plant for corm development
- Vase life: 7-10 days with preservative solution
- Corm harvesting: Lift corms 6-8 weeks after flower spike removal
Summary Cheat Sheet
| Crop | Key Production Point |
|---|---|
| Gladiolus | Use healthy corms and stake spikes to prevent lodging |
| Tuberose | Bulb size and timely planting decide spike and loose flower yield |
| Lily | Bulb quality, temperature regime, and harvest stage are critical |
| Common strategy | Maintain drainage, balanced fertigation, and rapid post-harvest cooling |
Tuberose (Polianthes tuberosa)
Introduction
Tuberose, also called "Rajnigandha", is valued for its fragrant white flowers used in garlands, perfumery, and essential oil extraction. It belongs to the family Amaryllidaceae.
Varieties
- Single: Shringar, Prajwal, Calcutta Single, Mexican Single
- Double: Suvasini, Calcutta Double, Pearl
- Semi-double: Vaibhav
Production Technology
| Parameter | Requirement |
|---|---|
| Climate | Warm and humid; 20-35°C |
| Soil | Well-drained loamy; pH 6.5-7.5 |
| Propagation | Bulbs (offsets); >1.5 cm diameter |
| Planting time | February-March (main crop); September (ratoon) |
| Spacing | 30 x 30 cm or 30 x 20 cm |
| Planting depth | 3-5 cm |
| Fertilizers | N:P:K at 200:200:200 kg/ha |
| Irrigation | Regular; avoid waterlogging |
Harvesting and Yield
- Harvest flower spikes when lower 2-3 pairs of florets have opened
- For concrete extraction, harvest fully open flowers
- Yield: 8-10 tonnes/ha of loose flowers; 2-2.5 lakh spikes/ha
- Ratoon crop possible for 2-3 years
Lily (Lilium spp.)
Introduction
Lily is a premium bulbous cut flower belonging to the family Liliaceae. It is gaining popularity in India as a high-value cut flower for bouquets, floral arrangements, and decorations.
Types and Varieties
| Type | Characteristics | Varieties |
|---|---|---|
| Asiatic hybrids | Upward-facing, unscented, early | Brunello, Navona, Tresor |
| Oriental hybrids | Large, fragrant, outward/drooping | Stargazer, Casa Blanca, Sorbonne |
| LA (Longiflorum x Asiatic) | Sturdy, medium fragrance | Brindisi, Courier, Royal Trinity |
Production Technology
- Propagation: Through bulbs (10-14 cm circumference for cut flower production)
- Growing medium: Well-drained mix of cocopeat, perlite, and soil (1:1:1)
- Temperature: 14-18°C (night) and 20-25°C (day)
- Spacing: 15 x 15 cm (12 x 12 cm for Asiatic)
- Planting depth: 10-12 cm (2-3 times the bulb height)
- Light: Partial shade; 50% shade net during summer
- Fertilizers: N:P:K at 150:100:200 kg/ha through fertigation
- Growth regulators: GA3 at 50-100 ppm for stem elongation
Harvesting
- Harvest when first bud shows colour (just before opening)
- Vase life: 10-14 days (Asiatic), 7-10 days (Oriental)
- Cold storage at 2°C after pulsing with preservative solution
