Beetroot Farming in India: Sowing Time, Varieties, Seed Rate, Fertiliser, Diseases, Yield, Cost and Profit per Acre

Beetroot is a cool-season root vegetable. Sow October to November in the north Indian plains and June to November in the south (Tamil Nadu sources say July to August; Kerala says August to January), at about 2.5 to 4 kg seed per acre, on ridges 30 to 50 cm apart, thinned to one seedling every 10 to 15 cm. Apply 8 to 10 tonnes of FYM per acre and borax (Bayer: 4 to 6 kg per acre). Roots are ready at 3 to 5 cm across, about 8 to 10 weeks after sowing for most types. Sources give 8 to 12 tonnes per acre; a 2020 Maharashtra survey averaged about 6.3 tonnes per acre at a cost near Rs 48,800 per acre.

Beetroot (chukandar, Beta vulgaris) is a root vegetable grown for its swollen, deep red root. It is eaten raw in salads, boiled, grated into dishes and pressed for juice. The tops are edible too. The same species also gives sugar beet and Swiss chard.

TNAU names Tiruppur, Coimbatore, the Nilgiris, Dindigul and Theni as growing districts in Tamil Nadu, with Mettupalayam, Coimbatore and Erode as the main markets. Kerala promotes it in the high ranges through VFPCK, and the 2020 survey we use for costs was done in Ambegaon and Junnar near Pune. It is grown across the north Indian plains in winter as well.

It is a short crop and a cash crop: most types are out of the ground in about two to three months. That is its attraction on small plots. The catch is that you are selling a fresh vegetable, so the price you get on the harvest day decides your profit far more than the yield does.

Sow so that the roots swell in cool weather. In the north Indian plains that means October to November. In the south the window is wider: Bayer gives June to November, TNAU says July to August for Tamil Nadu, and VFPCK gives August to January for Kerala. In all cases, aim for the 18 to 25 degree C range.

Why does temperature matter so much? Bayer says the best growth is at 18 to 25 degrees C, that about two weeks at 5 to 10 degrees C can push plants to bolt (send up a flower stalk), and that excessive heat causes zoning, which is alternating light and dark rings inside the root. A bolted or zoned beetroot sells badly. So do not sow in the hottest months on the plains, and in cold hill pockets do not sow so late that roots form in near-frost weather.

One trick that growers use to avoid a glut is staggered sowing. Sow a part of the field every two to three weeks inside your window, so that you harvest over a month instead of in a single week. If you are planning a winter vegetable block, our cool-season crops list and the radish (mooli) guide cover the crops that share this window. It works because roots left in the field too long crack and turn woody, as we explain in the harvest section.

Beetroot grows best in deep, well-drained, loose soil with a pH between 6 and 7. VFPCK says sandy loam is best, that it is sensitive to acidic soil and that it tolerates salt. Heavy clay or stony soil gives rough, forked roots and waterlogged patches invite root rot. Choose a field that drains well after rain.

If you do not know your pH, test it before you spend on seed. Our guide to soil pH and nutrient lock shows why a fertiliser can be in the soil and still not reach the plant, and how to read your soil health card turns the report into a dose.

The open-pollinated varieties named by the university and company sheets are Detroit Dark Red, Crimson Globe, Ooty 1, Red Ball, Early Wonder, Crosby Egyptian and Ruby Queen. Ask your local seed dealer which of these has done well in nearby fields.

How do you choose? Pick by your market first. Buyers in most Indian mandis want round, dark red roots of medium size with a small tap root. Then pick by your sowing window and by what the local seed shop can show you from real fields nearby. Avoid very late types if you want a quick cash crop.

The TNAU 120-day figure is for Ooty 1, a slow variety. Most other types are ready in 8 to 10 weeks, depending on variety and how big you let the root grow.

Plan on roughly 2.5 to 4 kg of seed per acre. TNAU gives 6 kg per hectare (about 2.4 kg per acre), VFPCK gives 7 to 8 kg per hectare (about 2.8 to 3.2 kg per acre) and Bayer gives 3 to 4 kg per acre. Sow 1.5 to 2.5 cm deep. The number of plants depends on your spacing, so work from the table below.

A beetroot "seed" is really a dry fruit holding several seeds, so a single piece can give two or three seedlings. That is why thinning is not optional. Without it, roots come up small, crowded and misshapen. VFPCK suggests mixing seed with fine sand for even sowing, and Bayer suggests dibbling seed mixed with sand or mud, or using seed balls.

Do not convert seed rate to bigha by guesswork. A bigha is a different size in different states. Take the per-acre figure and multiply by the share of an acre your local bigha covers.

Plough until the soil is fine and free of clods, because lumps make forked, misshapen roots. At the last ploughing mix in well-decomposed farmyard manure at 20 tonnes per hectare (TNAU, VFPCK), which is about 8 tonnes per acre. Bayer gives 8 to 10 tonnes per acre. Then form ridges and furrows, or raised beds if drainage is poor. The same ridge-and-bed approach is described in our cauliflower package of practices.

• Ridges and furrows. TNAU forms ridges 30 cm apart and sows on the ridge at 10 cm spacing. VFPCK forms ridges about 20 cm high and 45 cm apart and places seed 15 to 20 cm apart.
• Raised beds with drip. TNAU describes beds 120 cm wide with four rows, a 30 x 30 x 10 cm layout, and a drip lateral down the middle of each bed at 1.5 m intervals.
• Sowing depth. 1.5 to 2.5 cm. Deeper sowing delays the seedlings.
• After sowing. Give a light irrigation straight away so the soil stays moist until the seedlings are out.

Do not sow directly after a heavy rain into wet clay. A crust forms, and the small seedlings cannot push through. If a crust does form, break it gently with a light sprinkle of water.

There is no single national dose. TNAU gives 120:160:100 kg of N:P2O5:K2O per hectare (about 49:65:40 per acre), VFPCK gives 75:37.5:37.5 (about 30:15:15 per acre) and Bayer gives 30:40:25 kg per acre. All three add FYM. Test your soil first and use the dose that matches your soil and expected yield.

What does that mean in bags? Using VFPCK as the middle dose and the usual fertiliser analyses (urea 46 percent N, DAP 18:46:0, muriate of potash 60 percent K2O), one acre needs roughly 33 kg DAP, 25 kg potash and 53 kg urea. Put all the DAP and potash and about 20 kg of urea in at sowing. Top-dress about 33 kg of urea at 3 to 4 weeks. Using the Bayer dose, it is roughly 87 kg DAP and 42 kg potash at sowing, and 31 to 33 kg of urea as top dressing. Adjust it with a soil test.

Two practical cautions. Beetroot is a root crop, so do not over-feed nitrogen: lush leaves with small roots is the classic result. And keep top dressing away from the stem, as Bayer advises (7.5 to 10 cm from the plants), so that fertiliser does not scorch the crown.

If you irrigate through drip, TNAU gives a fertigation plan: of the 120:160:100 total, about 48 N, 20 P2O5 and 10 K2O per hectare in the first 30 days; 48 N, 12 P2O5 and 60 K2O in the next 60 days during early root development; and 24 N, 8 P2O5 and 30 K2O in the final 30 days. Note that the TNAU page spreads this over a 120-day crop. For a shorter-duration variety, compress the stages.

Beetroot needs more boron than most vegetables. When it is short, you see dark, corky patches inside the root, called internal black spot or heart rot. Bayer advises 4 to 6 kg of borax per acre to prevent it. Do not guess the dose: borax carries only about 11 percent boron and over-application can scorch plants. A soil test is the safe guide.

The symptom is the problem here, because you cannot see it until the root is cut. By the time the leaves look odd, the damage inside is already done. That is why Bayer treats it as a prevention step at sowing and why good growers add borax to the basal dose and do not wait.

Katyayani sells Boron 20, a boron fertiliser that corrects boron deficiency and can be used as a foliar spray or applied to the soil. Follow the pack directions together with your soil report.

Never apply boron more heavily than the label says in the hope of faster results. Too much boron burns leaf edges and can hurt the next crop.

Keep the soil evenly moist from sowing to harvest. Give a light irrigation after sowing and again after the nitrogen top dressing. Bayer puts the water need at about 20 to 30 mm per week depending on weather and soil. Avoid a long dry spell followed by heavy watering, because that is what splits and hardens roots.

Rather than a fixed calendar, use the finger test: if the top 2 to 3 cm of soil is dry and crumbly, water lightly. In cool, damp weather you may need none for a week.

A mulch between the rows also helps hold even moisture; see mulching types and depth.

Thin at about 20 days after sowing (TNAU), or three weeks (VFPCK), or when seedlings are 5 to 6 cm tall (Bayer), leaving one strong seedling at each spot, 10 to 15 cm apart. Hand weed 2 to 3 times and hoe shallowly. When roots begin to swell, earth up lightly so that shoulders do not turn green.

• Thinning. Pull, do not cut. Water the bed lightly afterwards.
• Weeding. Bayer advises first hand weeding and shallow hoeing at about 20 to 35 days after sowing, then again as needed. Keep hoeing shallow, because beetroot roots sit near the surface.
• Earthing up. VFPCK lists shallow hoeing and earthing up as the main intercultural operations. A light earthing up supports the plant and keeps the shoulder covered.

The main beetroot diseases in India are Cercospora leaf spot, downy mildew, powdery mildew, virus yellows, rust, and Rhizoctonia root rot or damping off. Leaf spot is the one you will meet most often. Seed-borne and soil-borne problems are best handled by clean seed, drained beds and rotation.

Do not spray for every yellow leaf. Pull up a few plants from a bad patch. Eaten or rotted roots mean soil pests or root rot. Spots with a purple edge on lower leaves mean leaf spot. A cut root with dark corky patches means boron. Each has a different fix.

Start by removing badly infected leaves and rotating crops. Spray right after the first symptoms. KAU lists copper oxychloride 50 WP at 2 g per litre, mancozeb 75 WP at 3 g per litre, carbendazim 50 WP at 1 g per litre, and hexaconazole 5 EC or propiconazole 25 EC at 1 ml per litre. For 200 litres of water per acre, that is a pack of 400 g, 600 g, 200 g or 200 ml.

Other sources differ a little. TNAU gives mancozeb at 2 g per litre and VFPCK gives Bavistin (carbendazim) at 2 g per litre. The KAU doses come from its beetroot leaf spot page; the others are from TNAU and VFPCK. Always match the dose to the pack label.

Beetroot is eaten raw or juiced, so follow the pre-harvest interval on the pack before you spray.

Katyayani lists K-Zeb mancozeb 75 WP, a mancozeb fungicide for spots, mildews and blights on vegetable and horticultural crops, and COC 50 copper oxychloride 50 WP, a copper fungicide for fruits and vegetables. These are the same actives that KAU and TNAU name for leaf spot; follow the pack label and the pre-harvest interval.

Spray coverage matters as much as the product: wet the under-surface of the lower leaves where spots start. Our notes on fungicide application methods explain nozzle, volume and timing.

Prevention is cheaper. Use clean seed, control weeds, remove crop residue after harvest and rotate away from beet and its relatives. Our crop rotation guide shows how to fit a break crop into the plan.

Sow on ridges or raised beds, avoid waterlogging, and treat the seed. TNAU suggests spot-drenching Rhizoctonia patches with carbendazim at 1 g per litre.

A biological option is Trichoderma. Katyayani's Trichoderma viride bio-fungicide page says it works against wilt, rot, blight and damping off in pulses, chilli, paddy, cereals, fruits and vegetables. Follow the pack for seed or soil use. You can also see what else we stock for the same problem in our damping-off collection.

If a patch of seedlings collapses, do not water more. Lift the irrigation, open the soil surface lightly and drench only that patch. Over-watering a damping-off patch is the fastest way to lose the whole bed.

Leaf miner, flea beetle, webworm, aphids, cutworm and leaf-eating caterpillars are the usual pests. VFPCK recommends a 2 percent neem and garlic oil emulsion for leaf miner, flea beetle and webworm. TNAU lists malathion 50 EC at 2 ml per litre for leaf miner and flea beetle. Start with scouting and with hand removal, and spray only when counts rise.

Bayer says to apply insecticides well in advance of harvest to avoid residue problems. For a vegetable that goes into salads, that advice is the one to follow.

For aphids, a neem-based spray is a low-risk first step. Katyayani's Activated Neem Oil is a neem insecticide for aphids, whiteflies, thrips, jassids and mites; follow the label dose. Keep field edges and weed hosts clean, because aphids come in from outside.

Most of these are cheap to prevent and costly to fix. A buyer will turn down cracked, forked or zoned roots, so watering rhythm, sowing date and boron decide how much of your crop is actually saleable.

Harvest when roots are 3 to 5 cm across. VFPCK and Bayer both give this size. Most types are ready in 8 to 10 weeks after sowing (VFPCK), while the TNAU page shows a 120-day cycle for the slower Ooty 1. Do not leave roots in the soil too long, because big roots turn woody and crack.

How to harvest: loosen the soil lightly, pull the plants by hand, shake off the soil and twist or trim the tops to leave a short stalk (VFPCK). Handle gently, because bruised or cut roots bleed and spoil sooner. Wash if your market wants it, and grade by size before you pack.

Most Indian growers sell fresh, within a day or two. If you must hold roots, trim the tops and keep them cool. Without cold storage, plan to sell within days.

Who buys? Local mandis, vegetable wholesalers, supermarkets and juice vendors. Sorting into even sizes and presenting clean, dark roots earns a better price than a mixed lot. If you can tie up with a local juice bar or hotel, you get a steady offtake for oversize roots that the mandi discounts.

Price changes by market and by week, and wholesale mandi prices are not what a farmer receives at the farm gate. Check Agmarknet or your own mandi on the harvest day before you plan your sale.

The sources give a wide range: 20 to 25 tonnes per hectare (about 8 to 10 tonnes per acre) from TNAU, 25 to 30 tonnes per hectare (about 10 to 12 tonnes per acre) from VFPCK, and 12 to 15 tonnes per acre from Bayer. A real-farm survey in Maharashtra averaged 155.8 quintals per hectare, about 6.3 tonnes per acre.

Why such a gap? Advisory figures describe good land, good seed and good management. A survey describes what farmers actually harvested. Plan on the survey number until you have a season of your own records.

A 2020 survey of 90 beet growers in Ambegaon and Junnar, Pune. It reports a total cost per hectare of Rs 152,607 for the smallest farms, Rs 130,428 for medium farms and Rs 104,786 for the largest, which is about Rs 61,760, Rs 52,780 and Rs 42,410 per acre. The cost per quintal was Rs 774.12 on average.

The paper also prints a few line items for the overall average. Hired labour was Rs 13,856.68 per hectare (11.48 percent of the total, about Rs 5,610 per acre), manures Rs 16,833.88 (13.95 percent, about Rs 6,810 per acre) and plant protection Rs 6,875.90 (5.70 percent, about Rs 2,780 per acre). Seed was 14.12 percent of the total, which works out to roughly Rs 6,900 per acre. The authors name high seed cost and labour shortage as the most serious problems, along with the cost of fertilisers and pesticides.

Your own cash cost may differ from the survey figures. The paper also finds that cost per hectare falls as the beet area on a farm grows.

Profit per acre is quintals per acre times price per quintal, minus cost. The Maharashtra survey gives a B:C ratio of 1.24 at overall level.

Net profit per acre = (quintal per acre x price per quintal) - cost per acre. The break-even price at the survey yield and cost is about Rs 774 per quintal (Rs 7.74 per kg). Replace the cost with your own bills.

How to read this: every cell is quintals x price minus a cost of Rs 48,800 per acre (the survey average). These are scenarios, not forecasts. Price is the biggest lever, and farm-gate price is usually below wholesale. A poor crop at a low price loses money, while a good crop at a fair price pays well.

So what should you do? Grow a small block first, sow in batches, and line up a buyer before harvest. Beetroot rewards growers who control watering, boron and the sowing date and who have an outlet, and it punishes those who plant a large area, then hope for the mandi.

Conclusion

Beetroot is a quick, cool-season crop that pays when you hit the weather window, thin properly, give boron, water evenly and harvest at 3 to 5 cm. Yield claims range from about 6 to 15 tonnes per acre, and a 2020 Maharashtra survey puts total cost near Rs 48,800 per acre with a B:C ratio of 1.24, so the price you get decides the profit.
