🌸 Jasmine

Understand jasmine cultivation, including species, varieties, propagation, pruning, plant protection, and postharvest handling.

Jasmine is one of the most important loose flower crops in India for garlands, worship, perfumery, and export value products. This lesson covers species, cultivation package, pruning, harvest, and postharvest handling for exam use.

Identity, Origin, and Uses

Scientific name: Jasminum spp. Family: Oleaceae Common names: Juhi, Chameli, Mogra, Malligai

Jasmine is native to tropical and subtropical regions and has long ceremonial and commercial importance in India and Asia. The major cultivated species are J. sambac, J. grandiflorum, and J. auriculatum.

Main uses:

  • Loose flowers for garlands, veni, and worship.
  • Extraction of jasmine concrete and absolute for perfumes.
  • Hair oils, attar, soaps, and cosmetics.
  • Some species are used for tea flavoring and traditional remedies.

Important Species and Varieties

Major species

  • J. auriculatum (Mullai)
  • J. grandiflorum (Pitchi/Spanish jasmine type)
  • J. sambac (Gundumalli/Mogra/Arabian jasmine)

Notable varieties and types

  • J. auriculatum: Parimullai, CO.1, CO.2, long and short bud types.
  • J. grandiflorum: CO.1 and CO.2 selections/mutants for loose flower and oil extraction.
  • J. sambac: Ramanathapuram gundumalli, Khoya, Double Mogra, and related local forms.

Climate, Soil, and Field Establishment

Jasmine performs best in warm summer and mild winter regions. J. grandiflorum and J. sambac are sensitive to frost.

Soil and site:

  • Well-drained sandy loam to clay loam with organic matter.
  • Sunny location and assured irrigation.

Field preparation:

  • Pits of about 45 cm x 45 cm x 45 cm are prepared at least one month before planting.
  • Fill pits with FYM, topsoil, and coarse sand mixture before transplanting.

Propagation, Planting, and Spacing

Jasmine is propagated by cuttings, layering, suckers, budding/grafting, and tissue culture.

Practical propagation points:

  • J. auriculatum: semi-hardwood cuttings.
  • J. grandiflorum: terminal cuttings.
  • J. sambac: terminal and semi-hardwood cuttings.
  • Rooting support: IAA/IBA dips are commonly used.

Recommended spacing and density:

Species Spacing Approx. plants/ha
J. auriculatum 1.5 m x 1.5 m 4,400
J. grandiflorum 2.0 m x 1.5 m 3,350
J. sambac 1.25 m x 1.25 m 6,400

Best planting period in many regions is monsoon; plantation can remain productive for around 10 to 15 years.

Nutrient, Irrigation, and Pruning Management

Nutrient response is strong, but excess nitrogen can increase vegetative growth at the cost of flowering.

Indicative fertilizer schedule:

Species N:P2O5:K2O (g/plant/year) Split strategy
J. auriculatum 60:120:120 Multiple bimonthly splits
J. grandiflorum 100:150:100 2 splits (monsoon and post-pruning)
J. sambac 60:120:120 2 splits (monsoon and post-pruning)

Foliar support:

  • Zinc and magnesium sprays before flowering improve output.
  • Iron sprays may be used to correct chlorosis.

Irrigation:

  • Commonly at 7-10 day interval depending on soil and climate.

Pruning:

  • Done to increase productive shoots and regulate flowering.
  • Typical pruning window: late Nov to Jan depending on species.
  • Usual pruning height: around 45-50 cm above ground.

Plant Protection

Key pests:

  • Bud worm
  • Red spider mite
  • Blossom midge

Key diseases:

  • Leaf blight
  • Wilt

Management is based on timely scouting, sanitation, and recommended insecticide/fungicide schedule as per local advisory.

Harvest, Yield, and Postharvest

Harvesting stage depends on end use:

  • For loose flower market: fully developed unopened buds.
  • For concrete extraction: fully opened fresh flowers.

Important point:

  • Delayed picking (late day harvest) reduces concrete quality and recovery.

Indicative flower yield and concrete recovery:

Species Flower yield (kg/ha) Concrete recovery (%)
J. auriculatum 4,733 to 9,152 0.28 to 0.36
J. sambac 739 to 8,129 0.14 to 0.19
J. grandiflorum 4,329 to 10,144 0.25 to 0.32

Packing and transport:

  • Cool flowers before packing when possible.
  • Use ventilated baskets/boxes with moisture-retaining lining for loose flowers.
