Baby corn is one of the easier exotic vegetables to grow in India: it is ordinary maize cut as a young, unfertilised cob 41 to 53 days after sowing, it needs no polyhouse, and a farmer near a city can fit up to four crops a year. It pays when there is a buyer for dehusked cobs, a dependable supply of true baby-corn seed, and labour for daily picking, which is the biggest single cost.
The best Indian cost figures come from a 2016-17 survey of 60 farmers in Sonipat, Haryana: about ₹45,700 per acre to grow, about 13 quintals of cobs per acre, and a net return near ₹58,400 per acre. Those figures are now several years old, so rework them with today's seed, labour and local prices.
Where it grows in India
- States: a Haryana agricultural university paper lists Meghalaya, western Uttar Pradesh, Haryana, Maharashtra, Karnataka and Andhra Pradesh as baby corn areas. ICAR trials have also been run in New Delhi, Allahabad (Uttar Pradesh), Goa and the north-western Himalayan mid-hills.
- Climate and season: it can be sown in rabi, summer and kharif. In a two-year ICAR Goa trial (temperature 19 to 35 °C), the rabi crop gave the best cob size and yield, summer crops matured earliest, and the rainfed kharif crop did worst because waterlogging and cool, humid weather slowed plants.
- Sowing date: at Allahabad, sowing on 30 October in the rabi season gave 35.79% more cob yield than 1 October and gave the best return of the three sowing dates tested (1 October, 30 October, 29 November).
- Soil: avoid places where water stands; waterlogging slowed the Goa kharif crop. The Goa trial grew it on acidic lateritic soil (pH 5.4) with added manure and fertiliser.
- Near a market: the Haryana paper notes demand is rising in urban areas and recommends crops near towns, since fresh cobs spoil quickly.
Varieties and hybrids
| Variety | Source | Traits in Indian trials |
|---|---|---|
| HM 4 | ICAR-IIMR (Directorate of Maize Research) | Single-cross hybrid popular for baby corn; first pick 53 days after sowing in the IIMR trial. At Allahabad it gave 8.68% more cob yield and 21.60% more fodder than VL Baby Corn-1. |
| VL Baby Corn-1 (VLBC-1), VL-42 | Vivekananda Parvatiya Krishi Anusandhan Sansthan, Almora | Early. VL-42 was earliest in Goa, at 44.67 days to harvest start. |
| COBC-1 | TNAU, Coimbatore | Smaller cobs in the Goa trial, so lower dehusked weight. |
| Madhuri | Directorate of Maize Research, New Delhi | Longest dehusked cobs in the Goa trial. |
| Golden Baby, G-5406, Mridula | Private-sector hybrids | Gave the highest net returns and benefit:cost ratio in Goa; Golden Baby was best on most traits in all three seasons. |
- IIMR also notes that nearly any early, prolific, medium-height single-cross maize hybrid can be used for baby corn, and rated its experimental hybrid CML 325 x CML 338 promising. That is a research line, not seed you can buy.
- Seed problem: 80% of the Sonipat farmers said standard, high-yielding baby corn seed was hard to find, and that seed supplied to them was often adulterated and costly. Their seed averaged about ₹537 per kg (₹5,368 for 10 kg an acre). Buy sealed, labelled seed from a known source and keep the bill.
Sowing, spacing and seed
- Seed rate: about 10 kg per acre (IIMR; the Sonipat farmers also used 10 kg).
- Spacing: trials used 60 x 15 cm (IIMR), 45 x 25 and 60 x 25 cm (Allahabad) and 50 x 30 cm (Goa). That is about 45,000 plants per acre at 60 x 15, about 36,000 at 45 x 25, and about 27,000 at 50 x 30 or 60 x 25. At Allahabad, HM 4 at 45 x 25 cm sown on 30 October gave the best gross return, net return and benefit:cost ratio.
- Detasseling: remove the tassel from every plant before it sheds pollen. IIMR calls this a key practice for baby corn since it increases the number of ears per plant (prolificacy), and it helps regardless of the sowing season.
Nutrition and irrigation
- IIMR (Delhi): 10 t farmyard manure per hectare 10 to 15 days before sowing, plus 180 kg N, 80 kg P2O5, 80 kg K2O and 25 kg zinc sulphate per hectare. That is about 4 t FYM, 73 kg N, 32 kg P2O5, 32 kg K2O and 10 kg zinc sulphate per acre. Phosphorus, potash and zinc go in as a basal dose, and nitrogen is split, with portions at the 4-leaf stage, the 8-leaf stage and before detasseling.
- Goa trial: 25 t FYM, 125 kg N (half at sowing, the rest one month later), 40 kg P and 30 kg K per hectare.
- What Sonipat farmers used: about 80 kg N, 24 kg P and 8 kg K per acre. A third of them said they did not know the recommended dose, so test the soil and ask the KVK. See fertilizers.
- Standing water harms the crop, as the Goa kharif results show, so choose drained fields. Most Sonipat farmers sowed on ridges. Drip irrigation can save water in summer crops.
- Pests: insects and diseases cost the Sonipat farmers a good part of their yield, and 30% blamed poor-quality pesticide. Baby corn is eaten fresh, so residues matter. Scout young plants for fall armyworm, use only products labelled for maize, and ask your KVK which ones are safe close to harvest. See pests.
Harvest and yield
- Stage: pick when the silk is 2 to 3 cm out, before pollination, within 1 to 3 days of silk emergence depending on season. In the Goa trial cobs were cut on the second day after silk appeared.
- Timing: first pick came 41 to 53 days after sowing at IIMR, and a crop gives 3 to 4 pickings. The first picking is the most uniform, with nearly 99% marketable cobs in IIMR's trial; the share of marketable cobs falls with later pickings.
- Quality standard: IIMR quotes export-quality cobs as 4 to 9 cm long and 1.0 to 1.5 cm across, pearly white to light yellow, cylindrical, free of pests and disease, with straight rows of small kernels. Keep the husk on until sale to hold freshness; a good husked-to-dehusked weight ratio is 5 to 6 to 1.
- Yield: the Sonipat farmers averaged 12.97 quintals of cobs per acre (11.8 on marginal farms to 14.2 on large farms). The paper does not say whether this is husked or dehusked weight; at the price it implies, about ₹75 per kg, it looks like dehusked cobs. Fodder from the remaining plants brought another ₹6,800 per acre.
- Fodder: the green plants left after picking are fed to cattle, as ICAR papers note, so the crop adds to dairy feed.
💡 Tip: Sow in batches a week or two apart so cobs arrive steadily for your buyer, and arrange transport before the first pick. Fresh cobs spoil quickly, which is why the Haryana paper recommends growing near towns.
Cost and returns
| Item (Sonipat, 2016-17, per acre) | ₹ |
|---|---|
| Harvesting labour | 8,588 (about 19% of cost) |
| Seed (10 kg) | 5,368 |
| Total variable cost | 26,654 |
| Fixed cost, including land rent value of 12,725 | 19,053 |
| Total cost | 45,707 |
| Cobs: 12.97 quintals | 97,313 |
| Fodder | 6,800 |
| Gross return | 104,113 |
| Net return over total cost | 58,405 (₹2.28 returned per ₹1 spent; cost of ₹3,523 per quintal) |
- Read this carefully: the average farm sold at about ₹75 per kg (₹97,313 divided by 12.97 quintals). If your price is ₹60 per kg and you harvest 8 quintals an acre, income from cobs is ₹48,000, barely above the Sonipat cost. Net return depends on yield and on selling price more than on any other factor.
- Large farms did best (net ₹67,824 per acre) and marginal farms worst (₹50,156), mainly through yield.
- No current (2025-26) cost or price survey was found, so check the local rate and see mandi bhav for vegetables, though baby corn is often sold on direct contracts.
Market and risks
- Buyers are hotels, restaurants and caterers, vegetable traders in cities, and canning or freezing processors. Sonipat farmers named lack of processing facilities (23%) and lack of awareness of value addition (35%) as problems, and the paper says value addition raises profit a lot.
- Main risks from the same survey: costly or fake seed (80%), high harvesting cost (60%), poor pesticide quality (30%), wrong fertiliser dosing (33%) and labour shortage at harvest (23%).
- Agree on size, colour and husk rules with the buyer before sowing. Cobs that are too long or have uneven rows are downgraded.
- For group selling and processing links see FPO and subsidy finder. For planning sowing dates see crop calendar. No baby-corn-specific subsidy was verified.
