Vetiver (Khus Grass) Organic Farming — Complete Guide India

Vetiver (Chrysopogon zizanioides), called khus or khus-khus in India, is one of the world’s most versatile grass crops. Its aromatic roots yield vetiver essential oil — one of the most prized ingredients in perfumery (used in Chanel No. 5, Dior Fahrenheit, and hundreds of luxury fragrances). The oil is steam-distilled from dried roots at 8–10 months, and organic certified vetiver oil commands ₹15,000–30,000/kg from international perfume houses and aroma chemical companies — making it one of the highest-value essential oils per kg globally. Additionally, vetiver has extraordinary soil conservation properties: its deep, dense root system (roots grow 2–4 m deep) prevents soil erosion on bunds and slopes — many Karnataka and other state governments subsidise vetiver planting for this purpose. Income: ₹50,000–2 lakh/acre from root oil, plus potential government subsidies for soil conservation use.

What Are the Two Completely Different Applications for Vetiver?

Essential oil production (commercial):

• Grow vetiver in rows; harvest roots at 8–10 months; steam-distil for oil
• Oil yield: 0.3–1.5% from fresh root weight; income ₹50,000–2 lakh/acre
• Requires access to distillation unit; buyers are aroma companies, perfumers, Ayurvedic companies

Soil and water conservation (bunds, slopes, channels):

• Plant in dense rows along bunds, farm roads, terrace edges, stream banks
• Roots prevent erosion; water infiltration improves; zero harvesting required
• Government subsidy available: NABARD, MNREGS schemes fund vetiver bund plantings
• Secondary income from leaf harvest (used for thatching and handicrafts at ₹3–8/kg)

For income-focused production: oil extraction model. For watershed management with supplementary income: bund planting model.

Which Vetiver Varieties Should You Use for Commercial Production?

• Dharanahalli (Java type, Chrysopogon zizanioides): The sterile, non-invasive commercial variety recommended by FAO; non-spreading; highest oil yield; recommended for all commercial production
• VRINAV (Sugandha): CIMAP selection; high root biomass and oil content; recommended for Deccan plateau conditions
• Sunshine type: South Indian ecotype; good adaptation to Karnataka dryland; good oil quality
• North Indian type (Himalayan vetiver): Slightly different oil profile; also commercial; sourced from Rajasthan and UP farmers

Critical note: Use only non-seeding sterile varieties (like Dharanahalli Java type) for agricultural planting. Wild or seeding types spread invasively and become difficult to remove.

What Soil and Climate Conditions Does Vetiver Tolerate?

Vetiver is extraordinarily adaptable:

• Grows in poor, degraded, saline, acidic, or alkaline soils (pH 3.3–12.5 — probably the widest tolerance of any cultivated grass)
• Tolerates annual rainfall of 200–2,500 mm
• Temperature: 5–55°C; truly remarkable range
• Waterlogging: tolerates temporary flooding and drought equally well
• Full sun required; does not grow in shade

Karnataka suitability: excellent across all districts. Even the most challenging dryland and degraded soils in Bellary, Chitradurga, and Raichur are suitable.

How Do You Plant Vetiver for Oil Production or Bunds?

For oil production (field planting):

• Spacing: 30 cm × 30 cm (approximately 14,500 plants/acre) for maximum root density
• Plant slips (divisions from established clumps) with 3–5 tillers each
• Plant at onset of monsoon (June–July) for best establishment; irrigation plantings any time
• Field preparation: one plough; 1 tonne vermicompost/acre broadcast and incorporated

For bund planting:

• Single row along bund top; 15–20 cm within-row spacing; no between-row spacing needed
• Plant dense enough that roots interlock within 2 growing seasons

What Organic Nutrition Does Vetiver Need?

Vetiver needs minimal external nutrition — it is adapted to poor soils. Over-fertilising produces excessive leaf at expense of root oil content:

• At planting: 1 tonne vermicompost/acre incorporated into soil
• At 3 months: Jeevamrutha drench 200 litres/acre — sufficient
• No additional nutrition needed for oil production crop

For maximum oil concentration: moderately fertile to poor soil + minimal irrigation during last 2 months before harvest (mild stress concentrates sesquiterpenes in roots).

How Do You Harvest Vetiver Roots for Oil Production?

Roots are ready at 8–10 months after planting in tropical conditions. Harvest indicators:

• Leaves partially dry down naturally; root growth has slowed
• During summer months (February–April) before next monsoon is ideal timing

Harvesting:

1. Irrigate 3–4 days before harvest to soften soil
2. Dig or mechanically harvest; roots typically 30–50 cm deep (some extend to 1 m)
3. Shake off soil; wash roots
4. Chop roots into 2–3 cm pieces; dry in shade for 2–3 days before distillation
5. Or dry completely to below 12% moisture; store for distillation in batches

Yield:

• Fresh root: 3–5 tonnes/acre
• Dry root: 1.5–2.5 tonnes/acre
• Oil yield from dry root: 0.5–1.5%
• Oil per acre: 7–37 kg

What Determines Vetiver Oil Quality and Who Are the Buyers?

Vetiver oil quality depends on:

• Variety (Dharanahalli Java type produces highest-quality perfumery oil)
• Soil type (well-drained red/laterite soils tend to produce finer oil than heavy clay)
• Root maturity at harvest (8–10 months is optimal; under-harvesting reduces oil)
• Distillation method (steam distillation; avoid hydrodistillation which degrades top notes)

Buyers: Nargis Perfumers (Kannauj), Ajmal Perfumes, International Flavors and Fragrances (IFF) India, Givaudan India all purchase certified organic vetiver oil. Register through Organic Mandya’s export liaison to access verified buyers.

What Is the Income Potential from Organic Vetiver Oil?

Scenario	Fresh root	Oil yield	Organic price	Revenue	Net
Conservative	3 tonnes	10 kg oil	₹18,000/kg	₹1,80,000	₹1.4 lakh
Standard	4 tonnes	20 kg oil	₹20,000/kg	₹4,00,000	₹3.6 lakh

Input cost per acre: ₹20,000–40,000 (including distillation cost or distillation access fee).

Selling dry root to distilleries (without own distillation): ₹80–150/kg dry root; net income ₹80,000–2.5 lakh/acre depending on yield.
