Tuberose cultivation

TUBEROSE (Polianthes tuberosa L.)


Tuberose commonly known as Rajni gandha. It produces waxy,  white and fragrant flowers on long spikes, which are mostly used as cut flowers; for making garlands and extracting essential oil.

Tuberose cultivation

Climate: Tropical conditions with a temperature range of 28 to 300C

Well drained loamy soil having a pH of 6.5-7.5 is ideal for cultivation.

Propagation and planting
Bulbs are used for commercial propagation. Bulbs (25 to 30 g) are planted (1,12,000 corms/ha) on the sides of ridges at 45 x 20 cm spacing at 2.5 cm depth during June – July. Bulbs are planted after 30 days of harvest. Dip the corms in 5000 ppm CCC (5 g/lit) before planting to increase the yield.

Micronutrients: Manuring and after cultivation
Manuring can be done with FYM 25 t/ha and NPK 200:200:200 kg/ha (IIHR Recommendation). Full P and K can be applied during the final preparation of plots, while N can be applied in 3 equal split doses i.e., at the final preparation of plot, 60 and 90 days after planting of bulbs.

Foliar spray ofZnSO4 0.5% + FeSO4 0.2% + Boric acid 0.1%.

Growth regulators: 
Foliar application of GA3 at 50 to 100 ppm thrice at 40, 55 and 60 days after planting.

Plant protection
Thrips: Spray Dimethoate @ 1.5 ml/lit or Fipronil 5 % SC @ 1.5 ml/ l

Aphids: Spary Dimethoate @ 1.5 ml/lit or Imidacloprid @ 1.5ml/l

Root knot nematode:
Apply Carbofuran 3 G 1 g/plant near the root zone and irrigate immediately to control nematode infestation.

Basal rot (or) stem rot: Soil drenching with Carbendazim @ 0.1 %

Crop duration
It extends up to 2 years. The crop can be maintained for one more year with good management practices.


For Loose flower and concrete extraction: Individual florets are plucked during early morning hours before 8 am daily, when they start to open.
For cut flower: Whole spike is cut leaving 4 to 6 cm from the base.

Loose flowers: 14-15 t/ha; Cut flower: 2 – 3 lakhs spikes/ha/year; Bulbs & bulblets: 20 -25 t/ha (at the end of 3rdyear).
Concrete recovery: 0.08 – 0.11 %
