Linseed (Alsi / Flaxseed) Farming in India: Cost per Acre, Sowing, Diseases, Pests, Yield and Profit

Linseed (alsi, flaxseed) is a cool-season rabi oilseed grown on about 3 to 4 lakh hectares in India, mostly in Madhya Pradesh, Chhattisgarh, Uttar Pradesh, Maharashtra, Bihar and Odisha. Sow from about the first fortnight of October to mid November (rainfed) in lines, using roughly 8 to 12 kg of seed per acre, and treat the seed first. In KVK demonstrations with improved practice, farmers got about 3 to 6 quintals per acre; the national average is far lower, around 1.6 quintals per acre by one 2021 paper. Total cost in the studies read was roughly Rs 6,500 to Rs 10,400 per acre. Linseed is not covered by central MSP, so your profit depends on the local mandi price: use the break-even formula in this guide. The main field problems are rust, wilt, powdery mildew, Alternaria blight and bud fly; early sowing and seed treatment help with most of them.

Yes. Linseed and flaxseed are one plant, Linum usitatissimum. Farmers call it alsi, tisi or jawas, depending on the state. The name changes with the purpose. Grown for seed oil, it is linseed. Grown for stem fibre, it is flax. Grown for both, it is dual-purpose flax. The KVK Sagar paper explains it this way, and it is worth knowing before you buy seed, because the fibre types and the oil types are not the same crop in practice.

The table says one thing plainly: if you are on plains land and want a rabi oilseed, you are growing the seed type. Fibre flax needs retting, a buyer for the straw and its own varieties, and we found no Indian price or buyer data for it. Talk to your KVK before putting an acre under fibre.

Mostly in Madhya Pradesh, Chhattisgarh, Uttar Pradesh, Maharashtra, Bihar and Odisha, with smaller pockets from the Himalayas to Karnataka and across the North-East. After rapeseed-mustard it is the second biggest rabi oilseed. A 2021 KVK paper puts India at about 4.36 lakh hectares and 1.67 lakh tonnes. FAOSTAT 2020 numbers, quoted in another paper, say about 3.2 lakh hectares and 1.74 lakh tonnes.

The figures do not match because the years and sources differ. We could not open a current state-wise table (area, production, yield by state), so there are no 2023-24 state numbers here. The Directorate of Economics and Statistics has one. The thing to take from all of this is the yield: India sits far below the world average, and the trial pages later in this guide show why.

Linseed wants a cool season and moderate moisture. The ICAR-AICRP guide gives 450 to 750 mm of annual rainfall, 25 to 35 degrees C for germination, 21 to 26 for flowering and 15 to 20 for seed filling. Loamy soil with pH 5.5 to 7.0 is preferred. KVK Sagar adds that drought and high heat early on or at seed filling reduce yield and quality.

Assam's package also prefers loamy soil. It suggests dolomitic lime at 65.5 kg per bigha, 15 days before sowing, where fields grow more than one crop a year. That advice is for acidic soil. Do not copy it to alkaline black soil. Before you buy any fertiliser, read your soil health card, because KVK Sagar is blunt that fertiliser doses should follow a soil test.

Linseed is a rabi crop. In rainfed areas sow in the first fortnight of October if the soil holds moisture (KVK Sagar). The Rewa demonstration sowed from 25 October to 10 November. The ICAR-AICRP guide says finish rainfed sowing by 15 November and irrigated by 25 November. You harvest in March to April.

Here is the trade-off. Sow too early into dry soil and the seed does not come up evenly. Sow too late and the crop flowers into warm, humid weather, which is when rust, powdery mildew and bud fly are worse. KVK Sagar says timely sowing helps the crop escape all three. So the rule on the ground is simple: sow as soon as the seedbed has moisture, and treat the middle of November as the last date, not the target.

If your paddy is late and the field is still wet in November, utera is the way out. The ICAR guide says relay sowing already covers about 25 percent of India's linseed area.

There is no one best variety for the whole country. The sources we opened name JLS-27 (Rewa, MP), JLS 66 and JLS 67 (rainfed Sagar, MP), T-397, Shekhar, Padmini and RLC-153 (Assam), Priyam and LSL-93 (Nagaland), and BAUP 101 and RLC-143 for utera. Ask your KVK which one is released for your zone, and buy certified seed with a tag and a bill.

Read the JLS 66 and JLS 67 row again. The improved varieties gave almost double what the farmers' own old mixed seed gave in the same village, same season. That gap is the cheapest yield you can buy. Three more names turned up only in search summaries: Sabour Tisi-1 (utera, north-eastern zone), Arpita (Odisha) and Varsha Alsi-2 (RLC 171, rainfed north and east). Treat those as leads for your KVK, not as recommendations. You may also see Nagarkot, Jeevan and Him Alsi-2 named for the Himalayan dual-purpose crop. We could not confirm them in any ICAR source we opened, so we leave them out.

Do not save seed from a field that had wilt or Cuscuta, and replace seed often. KVK Sagar names old mixed seed as one of the main reasons farmers get low yields.

Plough 2 to 3 times with a cultivator, then harrow 2 to 3 times to get a fine, moist seedbed. The Rewa package also did deep ploughing in April. Sow in lines 25 to 30 cm apart, 2 to 3 cm deep in moist soil or 5 to 8 cm if the topsoil is dry. About 15 days after the seedlings come up, thin to roughly 10 cm between plants (ICAR-AICRP).

• Use a seed drill, not your hand. KVK Sagar found that broadcasting gave poor germination and a patchy stand. Line sowing at 25 to 30 cm by 7 to 10 cm gave a better crop with fewer pests and diseases.
• Know your plant count. The ICAR guide aims for 4 to 5 lakh plants per hectare.
• Keep the seed in moisture. Linseed seed is small. If you drop it deep into dry soil, it will not come up.
• Narrow rows may pay. A Gujarat trial in 2021-22 found 22.5 cm rows gave the best seed yield and net return of three spacings (22.5, 30 and 45 cm). It was one season at one place, so treat it as a hint.

In line sowing, plan for 20 to 30 kg per hectare, which is about 8 to 12 kg per acre. Assam's package is lower at 15 to 20 kg per hectare (6 to 8 kg per acre). Relay broadcast needs 35 to 40 kg per hectare (14 to 16 kg per acre). Farmers who used 30 to 50 kg per hectare in the MP studies were wasting seed and growing a crowded, weak crop.

We have not converted seed to bigha. A bigha is a different size in every state, and a wrong conversion wastes seed or thins your stand. Ask the seller to weigh it for your local bigha, using 8 to 12 kg per acre as the reference. Seed size, purity and germination also change the right rate (KVK Sagar), which is another reason to buy tested seed.

Fungicide first, biofertilizer second. The sources do not agree on the product or dose, so match your state advice. They use thiram or Bavistin at 2.5 g per kg (ICAR-AICRP), carboxin at 2 g per kg for wilt (Assam), and in the MP trials Trichoderma at 5 g per kg with Azotobacter and PSB at 5 to 10 g per kg.

Bavistin is a carbendazim fungicide, and carbendazim is the usual seed-dressing choice in these trials. If you want a carbendazim product, the Katyayani range has carbendazim 50 WP. It is a general-purpose fungicide: its page lists root rot, collar rot and seedling blight, but it does not name linseed and gives no seed dose, so follow your KVK and the pack. For the biological step, Trichoderma viride lists wilt on its page, and Azotobacter lists oilseeds under field crops. Neither page names linseed or gives a dose.

Do the chemical dressing first and let the seed dry in shade. Add the culture just before sowing, so the live bacteria and the fungus are not hurt by the fungicide. The same two-step order is explained for another rabi crop in our chana seed treatment guide.

Rainfed linseed gets 40:20:20 kg of nitrogen, phosphorus and potash per hectare (about 16:8:8 per acre) at sowing. Irrigated gets 90:40:30 per hectare (about 36:16:12 per acre), with half the nitrogen held back for the first irrigation. Several MP trials add sulphur, and KVK Rewa says most of its district is short of it.

Assam also gives the product version: 88 kg urea, 125 kg SSP and 16 kg MOP per hectare, or 12, 18 and 2 kg per bigha (Assam bigha). That is about 36 kg urea, 51 kg SSP and 6.5 kg MOP per acre. The ICAR guide lists FYM or compost at 5 to 8 tonnes per hectare, dhaincha green manure and gypsum at 30 to 40 kg per hectare as options.

Pick the row that matches your water and soil, or better, your soil test. More nitrogen is not safer. The flax rust literature advises against excess nitrogen, and a lush crop is easier for rust. If you need a sulphur source, ammonium sulphate carries 21 percent nitrogen and 24 percent sulphur, so 25 to 40 kg of it per acre gives roughly 6 to 10 kg of sulphur (our arithmetic) and some nitrogen that you should subtract from your urea. The Katyayani ammonium sulphate page lists mustard among oilseeds but not linseed, and its printed doses are for other crops, so use the soil test rate. Our mustard fertiliser schedule shows how sulphur is handled in the neighbouring rabi oilseed.

Linseed is mostly rainfed, but one or two timely waterings lift yield. The ICAR-AICRP guide asks for at least two, at 35 and 65 days after sowing, and three (35, 55 and 75 days) if water is available. KVK Sagar says one at 30 to 40 days and one just before flowering when winter rain fails.

KVK Sagar also says many farmers wrongly believe linseed needs no irrigation, and counts this among the gaps behind low yields. In the Rewa demonstration the field was watered before sowing, at 35 days and at 70 days, which is seed setting. If you have water for only one round, give it near 35 days, before flowering. Both sources agree on that stage. Keep water off the field once capsules are filling and turning, and never let it stand in the rows.

Keep the field clean for the first 35 to 60 days. KVK Sagar says the crop suffers worst from weeds between 25 and 45 days after sowing. The ICAR guide suggests hand weeding twice, at 4 and 7 weeks. Assam says one weeding at 20 to 25 days, and Rewa did one hand weeding at 30 days.

KVK Sagar names the weeds to watch: Anagallis arvensis, Vicia hirsuta, Fumaria parviflora, Melilotus, Chenopodium album and Phalaris minor. Cuscuta (dodder) is the worst. It looks like thin yellow or orange string wrapped round the crop, and the ICAR review calls it a serious problem in some areas. If you see a patch, pull it out with the host plants and burn it before it sets seed. Never take seed from that field.

The sources name isoproturon, pendimethalin before emergence and metsulfuron-methyl after it. We did not check the current CIB&RC label for linseed for any herbicide, so we give no herbicide dose. Ask your KVK what is registered for linseed in your state and read the pack. If you want to see what is stocked, the Katyayani herbicides collection has 7 products, and none of them is promised for linseed here. Check the label line for linseed on the pack before you buy.

Four diseases matter most in India: rust (Melampsora lini), wilt (Fusarium oxysporum f. sp. lini), Alternaria blight and powdery mildew. The ICAR Journal of Oilseeds Research review lists the powdery mildew fungi as Oidium lini and Leveillula taurica. In an epidemic, these fungal diseases can cut yield by 80 to 100 percent. Minor ones include collar rot, damping-off and Botrytis rot.

We should be honest about this table. The ICAR review and the other sources we opened name these diseases and give the rust and wilt facts, but their abstracts did not describe powdery mildew or Alternaria symptoms in detail. The wording for those two, and for damping-off and Cuscuta, is a plain field description that we could not check against an Indian source in this session. Photograph the crop and show it to your KVK before you spend on a spray.

On the chemical side, the Rewa demonstration used a ready-mix of carbendazim plus mancozeb at 30 days. The Katyayani carbendazim 50 WP page lists powdery mildew, leaf spot and root rot, but it does not name linseed or give a dose, so it is a general option, not a linseed recommendation. To compare what else is stocked, see the fungicides collection. For how to spray properly (nozzle, water volume, covering the leaf), read our fungicide application methods guide. For wilt in another rabi crop, our chana wilt guide shows the same seed treatment and rotation logic.

Bud fly (Dasineura lini) is the pest that Indian linseed research keeps returning to. It is a tiny midge, and its maggots feed inside the flower bud. The bud swells and stays shut, and no capsule forms. A trial from 1995 to 97 put avoidable yield loss at up to 60.81 percent. Early sowing is the first defence. A spray at bud initiation comes next, if you actually see it.

Walk the field when the first buds show. Pinch a few swollen buds that have not opened. If you find tiny maggots inside, you have bud fly and the numbers matter. If the buds open normally, do not spray.

Read the Nagpur row slowly. The two sprays took yield from about 689 to about 1,100 kg per hectare, which is why the authors call it worthwhile. But those concentrations are what the trial used. They are not label doses, and we did not check the CIB&RC list for a linseed row. Ask your KVK or dealer for a product whose label lists linseed, and wear gloves, mask and full sleeves.

If you need an insecticide that shares the active used in the Nagpur trial, the Katyayani range has acetamiprid 20 SP. Be clear on what this is. Its page lists aphids, thrips, whiteflies and jassids and does not name linseed, bud fly or a dose. It is a general sucking-pest insecticide, so check the pack for linseed before you use it. The wider list is in the insecticides collection, which names soybean, cotton and chilli, not linseed.

On aphids and caterpillars we found no Indian source with thresholds for linseed, so we quote none. If you see aphid colonies on the growing tips, count them on 20 plants and compare with how winter aphids are scouted in rabi oilseeds. Our mustard aphid guide shows the method. Always confirm the product against a linseed label.

With improved practice, KVK demonstrations got about 3 to 6 quintals per acre (7.41 to 14.88 per hectare). Farmers' own practice in the same studies gave about 1.6 to 4.1 quintals. The all-India average sits far below both. Unless you follow the whole package, plan on the lower column.

So what closed the gap at Rewa? Five things together: a new variety, less seed (20 against 35 kg per hectare), line sowing, balanced fertiliser with sulphur, and seed treatment with a timely spray. The farmers' plots next door used no seed treatment, no hand weeding and no irrigation. None of these steps is costly. Skipping them is what costs.

In the studies we read, total cost was about Rs 16,000 to Rs 18,000 per hectare in two MP studies (about Rs 6,500 to Rs 7,300 per acre) and about Rs 25,600 per hectare in a Chhattisgarh farm survey (about Rs 10,400 per acre). These are old (2016 to 2019 and 2017-18) and indicative. We did not find an official line-item table of seed, labour and fertiliser costs, so the sheet below is for you to fill in with local prices.

Make your own sheet with these lines and your local prices: land preparation, seed (8 to 12 kg per acre times your seed price), seed treatment, fertiliser (use the per-acre table above), sowing, weeding labour for two rounds, irrigation or pumping, plant protection, harvesting and threshing, and transport. Add land rent if you pay it. Add it all up and divide by the quintals you expect. That is your cost per quintal, and you will use it in the profit section.

No. The Cabinet's rabi MSP list for the 2026-27 marketing season has six crops: wheat, barley, gram, masur, rapeseed and mustard, and safflower. Linseed is not one of them, so no support price waits for you at the mandi. You get whatever the local mandi or buyer pays on the day. We did not fetch a live mandi price, so check your nearest mandi (Agmarknet) before you sow or sell.

Who buys? KVK Sagar says about 80 percent of linseed oil goes to industry (paint, varnish, ink, soap), so your buyers are mostly oil mills and traders, not retail. We found no sourced buyer list or price series. Before sowing, ask two local traders what they paid last season and whether they will take your lot. That is the market check the studies skip.

The studies imply the prices they used in their years. Gross return divided by yield gives about Rs 3,700 per quintal at Rewa (2016-19) and about Rs 4,700 per quintal at Sagar (2017-19). Those are derived, old and not today's price. Our rabi MSP rates guide has the current list so you can compare other crops. A 2027-28 MSP release also appears to exist and we did not read it, so confirm the latest list on the PIB release page and the newer one.

Profit per acre is yield in quintals times your selling price per quintal, minus total cost per acre. Break-even price is cost divided by yield. In the studies, break-even came to about Rs 1,200 to Rs 3,200 per quintal. Above your break-even you earn. Below it you lose.

Be realistic about it. The best numbers come from supervised demonstrations. The Chhattisgarh survey of ordinary farmers shows a far thinner margin. Linseed looks best when your costs are low, your yield is decent, and the land would otherwise sit fallow after paddy. An ICAR journal paper from MP (Sagar, Hoshangabad, Mandsaur) concluded that linseed beat the main rabi crops under limited water, but its abstract gave no figures. For crop risk, see how rabi cover works in our PMFBY rabi registration guide. Whether linseed is notified in your district is something to check on the insurance portal, because we could not confirm it.

In utera or paira cropping you broadcast linseed seed into the standing paddy, 10 to 15 days before the paddy is cut. The seed grows on leftover soil moisture. The ICAR guide says this covers about 25 percent of India's linseed area. Use 35 to 40 kg of seed per hectare (14 to 16 kg per acre) and give 10 to 20 kg of nitrogen when seedlings are about 10 cm tall.

The ICAR North-East article explains why it fits that region. Most rice land lies fallow in rabi because of poor irrigation and early withdrawal of rain, and linseed is a hardy, short-duration crop that copes with moisture stress. Expect less: the ICAR guide gives 5 to 9 quintals per hectare for utera. Seed supply, markets and farmer awareness were the constraints. Sort out the buyer before you commit the area. And do not grow linseed after linseed in a field where wilt showed up.

Harvest the seed crop when about 90 percent of the capsules have turned brown and the seed looks shiny (ICAR-AICRP). Assam says wait until plants are dry and leaves have fallen. Harvest falls between March and April. At Rewa it was 15 to 25 March. Crop duration in Assam is 125 to 135 days.

• Cut when capsules are brown, not green. Early cutting gives shrivelled, low-oil seed.
• Dry on a clean floor, then thresh. Do not store damp seed, because it heats and spoils.
• Keep seed for sowing only from a healthy plot, and treat it again before the next sowing.
• Fibre crop: harvest about a month after flowering, as the ICAR guide says, not at capsule maturity.

Most linseed oil goes to industry: paint, varnish, printing ink, soap, linoleum and waterproof cloth. The seed is also eaten as a health food. Alpha-linolenic acid (ALA), an omega-3, makes up about 57 percent of the fatty acids. The cake left after pressing holds about 36 percent protein and is used as cattle feed and manure.

Conclusion

Linseed rewards the farmer who does the boring things on time: a certified variety, treated seed, line sowing, a timely watering or two, and a walk through the buds when flowering starts. Skip them and you will likely land near the national average of well under 2 quintals per acre. There is no MSP, so work out your break-even price before you sow and ask local traders what they paid last year. Where your KVK or state university gives a different date, dose or variety, follow them over this guide.
