Ashwagandha
Withania somnifera
A medicinal shrub, not a food crop — grown for its roots and berries, which are dried and sold into the Ayurvedic drug trade as one of India's best-known adaptogen herbs, at roughly ₹150–250 a kilo of dry root depending on grade. It is deliberately raised on the leftover fertility of a previous well-manured crop rather than fresh fertiliser, needs just one hand-weeding before its own canopy smothers the rest, and asks for almost no irrigation — but the one thing it cannot forgive is standing water, which rots the very root that is the whole point of growing it.

Quick Summary
Ashwagandha is a medicinal shrub, not a food crop — grown for its tapering roots and papery orange-red berries, which are dried and sold into the Ayurvedic and Unani drug trade, one of India’s best-known adaptogen herbs. There is no MSP; the price is set by drug-market demand for the root, graded mainly on thickness and cleanliness. It is grown above all in Madhya Pradesh, whose Neemuch–Mandsaur belt is the country’s largest trading hub, along with Rajasthan, Gujarat and Maharashtra.
What sets it apart from most crops here is how little it asks for. Government notes describe it as "mainly grown on residual fertility" — sown deliberately on land left over from a well-manured previous crop rather than fertilised in its own right. A single hand-weeding about a month after sowing is usually enough, because the plant’s own spreading canopy then smothers the rest, and it is genuinely rainfed: sown to catch the tail of the monsoon and largely finished on stored soil moisture, with irrigation kept back for a real dry spell.
The trade-off is that it cannot forgive the opposite mistake. Standing water at any stage — especially as the roots mature and the crop wants a dry finish — is its biggest disease risk, since it rots the very root the crop is grown for, so drainage and ridge or furrow planting matter. Sow with the monsoon, thin to a modest stand, and dig from January to March once the leaves have dried and the berries have turned yellow-red — the whole plant is uprooted, the stem cut just above the crown, and the roots cut into short pieces and sun-dried. The page below carries the residual-fertility approach, sowing method and plant density, the weeding and irrigation guidance, the drainage requirement, the harvest and root-drying steps, and dry-root yields and the price range.

Overview
Ashwagandha (Withania somnifera) is not a food crop — it is a medicinal shrub of the nightshade family grown for its tapering, fleshy roots and its papery-husked orange-red berries, both dried and sold into the Ayurvedic and Unani drug trade. The National Medicinal Plants Board (NMPB), under the Ministry of AYUSH, lists it among its priority herbs, and it has no Minimum Support Price — its price is set entirely by drug-market demand for the root, graded mainly on thickness and cleanliness.
What makes Ashwagandha unusual among the crops on this site is how little it asks for. Government cultivation notes are explicit that it is "mainly grown on residual fertility" — deliberately sown on land left over from a well-manured previous crop rather than fertilised in its own right — and that a single hand-weeding around a month after sowing is usually enough, since the plant's own spreading canopy takes over from there. It is also genuinely rainfed: it is sown to catch the tail of the monsoon and largely finishes on stored soil moisture, with irrigation reserved for a genuine dry spell. The trade-off is that it is unforgiving of the opposite mistake — waterlogging at any stage, and especially as the roots mature, is the crop's single biggest disease risk.
It is grown mainly in Madhya Pradesh — whose Neemuch–Mandsaur belt is India's largest Ashwagandha trading hub — along with Rajasthan (where the Nagaur district's "Nagori" strain is a well-known name in the trade), Gujarat, Maharashtra, and smaller acreages further north and south. It is sown with the monsoon (June–July) and dug for market from January to March, 150–180 days later.
Crop timeline, sowing to harvest
A quick visual map of the season — jump to any section below for the detail behind each stage.
- Day 0
Sowing
After pre-monsoon showers bring the soil to a fine tilth, seed is broadcast directly in the field (typically the second week of July) — or sown a little earlier in a nursery bed for transplanting later.
- Day 6–10
Germination
Nursery-sown seed germinates in about 6–7 days under light soil cover; direct-sown seed comes up over a similar window once there is enough soil moisture.
- Day 25–35
Thinning, weeding & transplanting
A direct-sown stand is thinned by hand to about 20,000–25,000 plants/ha and hand-weeded in the same pass; nursery seedlings of this age (5–6 weeks for the oldest) are transplanted into 60×60 cm furrows.
- Day 35–150
Vegetative growth on the monsoon
The plant grows almost entirely on standing soil moisture and monsoon rain, needing little to no irrigation through this stretch; its own canopy closes in and suppresses further weed growth.
- Day ~150 (December)
Flowering & fruiting
Small greenish flowers appear and set into berries that ripen from green to a papery orange-red husk — the clearest field sign the crop is heading into maturity.
- Day 150–180
Leaf-drying & root maturation
Leaves begin to dry and fall as the roots finish bulking; the crop actually wants a dry finish here — one or two late-winter showers help root development, but standing water at this stage is the single biggest risk to the crop.
- Day 150–180 (Jan–Mar)
Harvest
Once the leaves have dried and the berries have turned yellow-red, the whole plant is uprooted, the stem is cut 1–2 cm above the crown, and the roots are cut into 7–10 cm pieces and sun-dried.

Grown here
Climate requirements
Ashwagandha is planted specifically to use the tail of the monsoon and then dry out — it is often grown on land that cannot profitably carry an irrigated food crop for exactly this reason. The climate risk is not too little rain but too much of it at the wrong time: excess rainfall or standing water is explicitly flagged as harmful to the crop, particularly as the roots are bulking up and maturing.
Ideal temperature
20–35°C suits it best; a genuinely dry growing season, with just one or two late-winter showers near maturity, is what actually develops the roots well
Rainfall
500–750 mm — sown to catch the tail end of the monsoon and grown mostly on the soil moisture left behind once the rains ease off
Humidity
Tolerates the monsoon's humidity fine while it is establishing, but wants a dry season for most of its growth after that — continued wet, humid weather past establishment is what favours seedling and leaf blight
Sunlight
Full, open sun — it is not a shade-tolerant crop
Soil requirements
Land selection matters more than land preparation for this crop. Because Ashwagandha is deliberately grown on residual fertility and rainfed moisture, the choice of field — well-drained, on the lighter side, with some carry-over fertility from the last crop — does more to decide the outcome than anything done to the soil once Ashwagandha itself is sown.
Suitable soil
Sandy loam or light red soil — often deliberately the marginal, non-irrigated land on a holding rather than the best-watered field, since the crop is meant to be grown low-input
pH range
7.5–8.0
Drainage
Must drain freely — standing water rots the roots and is the single biggest disease risk this crop carries
Organic matter
Low input by design: the crop is raised mainly on the residual fertility left by a well-manured previous crop, not on fresh manure or fertiliser applied for Ashwagandha itself
Land preparation
Same four steps whichever region you are in — only the timing shifts with the sowing window.
- 1
Work the soil to a fine tilth after the pre-monsoon showers
Plough, disk or harrow once the first pre-monsoon showers have softened the ground, then level with a plank (pata) — this is timed to the rain, not a fixed calendar date.
- 2
Pick marginal, well-drained land over your best-watered field
Since the crop is meant to run on residual fertility and rainfall alone, land that cannot profitably carry an irrigated food crop is often the better choice for Ashwagandha, provided it drains well.
- 3
Skip the fresh manure application
Unlike almost every other crop on this site, government production notes explicitly do not recommend applying fresh FYM or fertiliser for Ashwagandha — it is meant to draw on what a previous, well-manured crop left behind in the soil.
Seed information
How the main varieties compare, so you can pick by duration, yield, disease pressure or what you are growing for.
| Variety | Duration | Yield | Disease resistance | Best state | Suitable for |
|---|---|---|---|---|---|
Released in 1989 by Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Mandsaur — the older of the two Ashwagandha varieties on ICAR-DMAPR's own official released-varieties list. A short-statured, high-alkaloid line bred for high-density planting. | ~180 days to root maturity | Total withanolide content of about 0.30% in dry root (species-level figure ICAR-DMAPR cites for this line) | Not stated in the official release record | Madhya Pradesh | General cultivation, high-density planting |
Released in 1998, also by JNKVV, Mandsaur — the second variety on ICAR-DMAPR's released list, sharing JA-20's short-statured, high-density-planting, high-alkaloid profile. | ~180 days to root maturity | Total withanolide content of about 0.30% in dry root | Not stated in the official release record | Madhya Pradesh | General cultivation, high-density planting |
Registered by CSIR-CIMAP, Lucknow, through half-sib selection specifically for drought-prone areas — the highest dry-root-yielding Ashwagandha variety documented on this site. | ~180 ± 20 days to root maturity | 34.95 quintals/ha dry root in its registration trial, against 21.99 quintals/ha for the best check variety | Bred for drought tolerance rather than disease resistance; not documented as disease-resistant | Rajasthan, Madhya Pradesh, Gujarat (drought-prone tracts) | Rainfed and marginal land |
Released in 2018 by CSIR-CIMAP, Lucknow, from a Nagouri × Kashmiri hybrid — the only Ashwagandha variety documented here with a specific disease-tolerance trait, and prized for its root textural quality. | 168–178 days to root maturity | 9–10 quintals/ha dry root, average | Tolerant to leaf blight | Madhya Pradesh, Rajasthan, Gujarat | General cultivation, valued for root quality |
Released in 2011 by CSIR-CIMAP, Lucknow, through half-sib family selection out of Nagori Ashwagandha stock — a high-yielding, semi-vigorous line bred for medium-irrigated areas, with dry root yield about double the check variety it was compared against. | ~180 days to root maturity (species-level harvest window) | Dry root yield of 11.77 quintals/ha in the variety's own registration trial, against 5.45 quintals/ha for the check variety — roughly double | Not stated in the variety's registration trial record — that trial evaluated and documents yield and withanolide content, not disease reaction | Rajasthan | — |
A high-yielding Ashwagandha line developed and marketed by CSIR-CIMAP, Lucknow — contact the institute directly for seed and planting-material availability. | ~180 days to root maturity (species-level harvest window; a perennial-type line that can also be held over more than one season) | Dry root yield of about 14 quintals/ha with a total withanolide content of about 0.25%, evaluated alongside CIMAP-Pratap and other CIMAP lines in multi-year cultivar trials | Not stated in the multi-year cultivar trial data — that trial evaluated and documents yield and withanolide content, not disease reaction; Poshita is a perennial-type line, unlike the annual-type JA-20/JA-134/CIMAP-Chetak | Uttar Pradesh | — |
A local Ashwagandha strain traded under the well-known name "Nagori", after Rajasthan's Nagaur district — prized for its starchy root, but not a formally released ICAR or state-university variety. | Not separately documented — treat as the species-level 150–180 days | No separately documented yield figure; traded on its starchy-root quality rather than a stated yield advantage | No rating exists — Nagori is farmer-saved landrace seed that has never been through a formal variety trial | Rajasthan | — |
- Seed rate
- 5–12 kg/ha for direct broadcast sowing (2–5 kg/acre); a nursery raised for transplanting needs only about 5 kg/ha of seed to produce enough seedlings
- Certified seed
- A genuine, named release — JA-20/JA-134 from JNKVV, or a CIMAP line like CIMAP-Pratap (highest yielding, drought-prone areas), CIM-Pushti (leaf-blight tolerant), CIMAP-Chetak or Poshita — is worth seeking out from JNKVV or CSIR-CIMAP, Lucknow, but most Ashwagandha in trade is still grown from farm-saved or locally-traded seed — Rajasthan's Nagaur belt in particular trades under the well-known local name "Nagori", prized for its starchy root, without being a formally released variety.
- Spacing
- 60 cm × 60 cm for a transplanted crop; a direct-sown stand is thinned at 25–30 days to about 20,000–25,000 plants/ha
- Seed treatment
- Treat seed with Captan at 5 g/kg before broadcast sowing, or with Dithane/Diathane M-45 at 3 g/kg before nursery sowing — both guard against seed rot and seedling blight in the first weeks.
Sowing guide
Direct sowing is the cheaper, lower-labour route and is what most growers actually use, but it needs a firm thinning at 25–30 days to bring the stand down to the right density. Transplanting gives a more even, controlled stand from the start at the cost of raising and moving a nursery.
- Best time
- Direct sowing: the second week of July, once pre-monsoon showers have brought the soil to a fine tilth. Nursery sowing: just before the monsoon properly sets in, with seedlings ready to transplant 5–6 weeks later.
- Row spacing
- 60 cm (transplanted crop)
- Plant spacing
- 60 cm (transplanted); thinned to an even stand if direct-sown
- Sowing depth
- Shallow — 1–3 cm
- Method
- Either broadcast directly into the prepared field, or raise seedlings in a nursery bed under light soil cover and transplant them into 60 cm furrows once they are 5–6 weeks old.
Fertilizer schedule
A split dose beats one large dose applied at sowing — nitrogen especially is lost to the air and to leaching if it all goes in on day one.
- 1
None, by design
Land preparation
Government production notes are explicit that Ashwagandha is grown mainly on the residual fertility left by a previous, well-manured crop — no fresh manure or fertiliser is routinely recommended for the crop itself.
- 2
Optional light NPK
Basal, at sowing
On land with genuinely poor carry-over fertility, a modest 20:20:0 kg N:P:K per hectare is sometimes applied — growers who do this are advised to keep the plant population on the lower side to compensate.
Irrigation schedule
1. Establishment
At/soon after sowing or transplanting
A light shower or a single irrigation helps seedlings establish; often not needed at all if the monsoon is running on schedule.
2. Dry monsoon spells
Through vegetative growth
A life-saving irrigation only if there is a genuine, extended gap in the monsoon — this crop is grown rainfed by design, not topped up on a fixed schedule.
3. Root maturation
Late season (Dec–Feb)
The crop wants dryness here, not water — one or two natural late-winter showers help the roots finish developing, but irrigating at this stage is far more likely to cause harm than good.
Critical stages
- Establishment
- Root maturation (needs dryness, not water)
Water-saving tips
- Ashwagandha is chosen specifically as a rainfed crop for land that cannot profitably irrigate a food crop — it is not a candidate for drip or sprinkler investment, and treating it as one misreads what the crop is for.
- Unscheduled, "just in case" irrigation late in the season is the most common way growers unintentionally cause root and collar rot in this crop — when in doubt, leave it dry.
Weed management
Common weeds
Organic control
- One hand-weeding, done at 25–30 days after sowing or transplanting, is usually enough on its own.
- On a direct-sown crop this weeding is combined with thinning the stand down to the target population — the two jobs are typically done in the same pass.
Chemical control
- No standard herbicide programme is documented for Ashwagandha — it is a hand-weeded crop, and its own dense canopy after establishment does most of the remaining weed suppression.
Nutrient deficiency identification
What a shortage of each nutrient actually looks like on the plant, so you can tell a deficiency apart from a disease before you spray the wrong thing.
Nitrogen
Visible symptom
Pale, weak, stunted growth on genuinely poor land that carries little residual fertility from a previous crop — the standard fix for this crop is choosing better residual-fertility land next season, not routinely fertilising it.
Phosphorus
Visible symptom
Weak early root and branch development on very poor soils — where fertiliser is used at all, phosphorus makes up half of the modest 20:20:0 kg N:P:K/ha dose sometimes recommended, alongside a lower plant population.
Diseases to watch for
Symptoms, likely cause and what actually treats it — not just a spray name.
Damping-off / seedling blight
- Symptoms
- Seed rots in the soil before it emerges, or young seedlings collapse at the collar within the first few weeks, in the nursery bed or a wet patch of a direct-sown field.
- Cause
- Soil-borne fungi favoured by excess moisture right at sowing and germination — one of the two major diseases government cultivation notes name for this crop.
- Treatment
- There is no rescue once seedlings have collapsed; remove and avoid re-sowing the same wet patch until drainage improves.
- Prevention
- Treat seed before sowing — Captan at 5 g/kg for direct sowing, or Dithane/Diathane M-45 at 3 g/kg for nursery sowing — and never sow into waterlogged soil.
Alternaria leaf blight
- Symptoms
- Brown to grey spots on the leaves that enlarge into blighted patches in humid weather, cutting down the leaf area feeding the roots.
- Cause
- An Alternaria fungus favoured by humid conditions once the crop is established — the other major disease named in government cultivation notes for Ashwagandha.
- Treatment
- Spray Dithane M-45 at 3 g/litre of water once the crop is about 30 days old, repeating at 15-day intervals if the disease keeps spreading.
- Prevention
- Treated seed reduces the initial disease load; avoid overly dense, poorly-drained stands that stay humid at canopy level.
Root & collar rot
- Symptoms
- Rotting and discolouration at the root and collar in waterlogged patches; affected plants wilt and their roots are unmarketable.
- Cause
- Soil-borne fungi favoured by standing water — the single biggest disease risk in a crop that is otherwise grown to finish dry.
- Treatment
- Improve drainage in the affected patch immediately; there is no reliable in-season cure once roots have rotted.
- Prevention
- Never let water stand around the crop — this is exactly why well-drained land and rainfed (not scheduled) irrigation are the standard practice for Ashwagandha.
Pests to watch for
What to look for before the damage is visible, and organic options before you reach for a chemical.
Stem borer
- Identification
- Caterpillars boring into the stem — one of the two major insect pests government cultivation notes name for Ashwagandha.
- Damage
- Weakens or kills the shoot it has bored into, cutting the plant's overall vigour and root bulking.
- Organic control
- Hand-pick and destroy affected shoots where the infestation is light, and keep the field free of alternate host weeds.
- Chemical control
- A fenvalerate-based insecticide (Sumicidin) at about 10 ml/litre is the spray government notes cite when the borer population is clearly damaging the crop.
Mites
- Identification
- Tiny mites feeding on the underside of the leaves — the other major pest named in government cultivation notes for this crop.
- Damage
- Leaf stippling and curling that saps the plant's vigour, though this crop otherwise sees relatively little pest pressure.
- Organic control
- A neem seed kernel extract spray is the specifically recommended organic control for mites on Ashwagandha.
- Chemical control
- A recommended acaricide only if the neem-based spray is not keeping the mite population down.
Common mistakes to avoid
The mistakes that cost growers the most, ranked by how often they show up in the field — not in the order you might expect.
- 1
Applying fresh manure or fertiliser the way you would for a normal crop.
Why it hurts
Wastes money for little real return — Ashwagandha is specifically grown on the residual fertility of a previous well-manured crop, not fed in its own right.
- 2
Sowing before the soil has properly received its pre-monsoon showers.
Why it hurts
The standard sowing window (second week of July) is timed to the rain, not the calendar — sowing into dry, unprepared soil gives a poor, patchy germination.
- 3
Skipping the seed treatment before sowing.
Why it hurts
Untreated seed is far more exposed to seed rot and seedling blight in the crop's first, most vulnerable weeks — Captan or Dithane M-45 treatment is cheap insurance against both.
- 4
Leaving a direct-sown stand unthinned past 25–30 days.
Why it hurts
An overcrowded stand competes for the same limited rainfed moisture and produces thinner, weaker roots than a properly thinned 20,000–25,000 plants/ha population.
- 5
Irrigating on a fixed schedule instead of only when genuinely needed.
Why it hurts
Unnecessary watering, especially late in the season, is the single most common way growers cause root and collar rot in what is meant to be a dry-finishing crop.
- 6
Harvesting before the leaves have dried and the berries have turned yellow-red.
Why it hurts
Roots dug too early are immature and lighter — wait for both signs of maturity together before uprooting.
- 7
Growing the crop on heavy, poorly-drained land.
Why it hurts
This is the single biggest disease risk the crop carries — standing water rots the root and collar, which is the entire economic product.
- 8
Rough handling of dried roots during cleaning, beating and transport.
Why it hurts
Buyers pay a real premium for clean, unbroken, well-graded root — careless handling breaks pieces and drops the whole lot into a lower grade.
- 9
Growing the crop without first checking who will actually buy it.
Why it hurts
Ashwagandha has no MSP and no mandi-style open market the way food crops do — it is traded on quality and grade directly with drug-market buyers, so a grower without a buyer lined up in advance carries real price risk.
Harvesting
January to March, 150–180 days after sowing, once the leaves have dried and fallen and the berries have turned from green to a papery yellow-red — that colour change, together with the leaf drying, is the clearest sign the roots are mature.
Signs it is ready
- Leaves dried and falling
- Berries turned yellow-red
- Roots plump with the skin firmed up rather than soft
Tools
- Spade or plough to uproot the whole plant
- Sharp knife to cut the stem 1–2 cm above the crown and to cut roots into 7–10 cm pieces
- An open, clean area for sun-drying
Expected yield
400–500 kg/ha of dry root under normal rainfed management (roughly 650–800 kg fresh before drying), plus about 50–75 kg/ha of seed threshed out from the dried berries.
Post-harvest & storage
Storage
Dried roots are cleaned, trimmed and graded by thickness before being stored in a dry, moisture-proof place that keeps them from reabsorbing damp and moulding.
Packaging
Roots are beaten with a club, or lightly threshed, to knock off adhering soil and the thin, brittle lateral rootlets, then trimmed with a knife and sorted by grade before bagging for the buyer. Berries meant for next season's seed are threshed and dried separately from the root lot.
Transportation
Handle dried root carefully — breakage and dust lower the grade, and buyers pay a genuine premium for clean, unbroken, well-sorted pieces.
Shelf life
Well-dried, properly graded root stores for a reasonably long period in a dry, moisture-proof store; seed kept for the next sowing should be stored separately and used the following season rather than held indefinitely.

Frequently asked questions
Does Ashwagandha have an MSP?
No. Ashwagandha is not on the government's list of MSP-notified crops — that list covers cereals, pulses, oilseeds and a few commercial crops, not medicinal plants. The National Medicinal Plants Board (NMPB), under the Ministry of AYUSH, recognises it as a priority herb and offers cultivation subsidy support through its schemes, but there is no price floor — the crop is sold entirely on negotiated price and grade to drug-market buyers.
Why is fertiliser not recommended for this crop?
Government production notes are explicit that Ashwagandha is meant to be grown mainly on the residual fertility left behind by a previous, well-manured crop, not fed fresh manure or fertiliser in its own right. This is part of why it is often planted on marginal, non-irrigated land rather than a farm's best field — it is a deliberately low-input crop by design, not an oversight.
Should I direct-sow or raise a nursery and transplant?
Direct sowing (broadcasting seed into the field around the second week of July) is cheaper and lower-labour, and is what most growers use — but it needs a firm hand-thinning at 25–30 days to bring the stand down to about 20,000–25,000 plants/ha. Transplanting nursery-raised seedlings at 5–6 weeks old into 60×60 cm spacing gives a more even, controlled stand from the start, at the cost of raising and moving a nursery.
Which variety should I plant?
JA-20 and JA-134, both released by JNKVV, Mandsaur, are the two Ashwagandha varieties on ICAR-DMAPR's own official released-varieties list. CSIR-CIMAP, Lucknow, has since released several higher-yielding lines: CIMAP-Pratap (34.95 quintals/ha dry root in its registration trial, bred for drought-prone areas), CIM-Pushti (9–10 quintals/ha, leaf-blight tolerant, released 2018), CIMAP-Chetak (bred from Nagori stock for medium-irrigated land) and Poshita (~14 quintals/ha in multi-year trials). That said, much of the crop actually traded in India — including Rajasthan's well-known "Nagori" strain — is still grown from farm-saved or locally-traded seed rather than a formally released variety.
When and how do I harvest Ashwagandha?
Harvest January to March, 150–180 days after sowing, once the leaves have dried and the berries have turned from green to yellow-red. Uproot the whole plant, cut the stem 1–2 cm above the crown, cut the roots into 7–10 cm pieces, and sun-dry them. Berries are hand-plucked or threshed separately to recover the seed.
What are the main pest and disease risks?
Government cultivation notes name stem borer and mites as the main insect pests, and seedling blight/damping-off and Alternaria leaf blight as the main diseases — but by far the biggest risk to the crop is waterlogging, which causes root and collar rot at any stage and is the reason Ashwagandha is grown on well-drained land with irrigation kept to a genuine minimum.
