Tomato Farming in India: Varieties, Season, Spacing, Fertigation, Pests, Diseases, Yield and Cost per Acre

Tomato is grown across India for much of the year, but each region has its own planting window, so confirm yours with the state agricultural university or KVK. Pick the growth habit first: determinate types stay short and bear over a shorter window, indeterminate types need staking and give a long harvest. Raise seedlings under net for about 25 days, plant 60 x 45 cm (determinate) or 75 x 30 cm (indeterminate), stake at 30 days, and feed in splits. Water evenly to avoid blossom end rot and cracking. Watch for fruit borer, Tuta absoluta, whitefly and leaf curl virus, then early and late blight and wilts, and use only sprays registered for tomato on the CIB&RC list. A Raipur sample study and a fill-in cost sheet are given for costing.

Tomato is one of India's most widely grown vegetables, raised in plains, hills and protected structures. Prices swing hard from season to season, so planning the planting window, the type and the market matters more than area.

An older cost study from Chhattisgarh lists Bihar, Karnataka, Odisha, Andhra Pradesh, Maharashtra, Madhya Pradesh, Chhattisgarh and West Bengal as major producing states, and says tomato there is grown in both kharif and rabi seasons. The Plant Archives paper is dated, so treat that list as a general guide to where the crop sits, not a current ranking.

For a grower, the point is simple. Tomato is not one crop calendar. A farmer near Bengaluru, a farmer in the Himachal mid hills and a farmer in Raipur plant at different times and fight different pests. The rest of this guide gives the common method first and then points to the places where your state recommendation should override it.

Tomato does best in a warm, frost-free season on well-drained sandy loam rich in organic matter, with soil pH about 5.0 to 7.0. Fruit set drops in very hot or very cold weather. Waterlogged or heavy clay beds raise the risk of wilt, root rot and blossom end rot.

The Assam package recommends well drained sandy loam with pH 5.0 to 7.0 and says lime at 10 q/ha every three years, based on a soil test, can lift acidic soil. Fruit set falls in very hot or very cold spells, so pick a planting window that avoids both. Heat-tolerant hybrids are sold by seed companies, so ask for the temperature range in writing.

• Pick a field that drains. If water stands for more than a day after rain, make raised beds or choose another plot.
• Do not follow tomato with another solanaceous crop. TNAU says to avoid planting solanaceous crops after tomato when managing Tuta absoluta. Brinjal, chilli, potato and tomato share pests and diseases.
• Test the soil first. pH and organic carbon decide how much lime, FYM and calcium you need. Our post on crop rotation examples shows where a non-solanaceous crop fits.

Determinate tomatoes grow to a set height, flower together and give most of their fruit in a shorter window. Indeterminate tomatoes keep growing and flowering, so they give a long harvest and need staking. Semi-determinate types sit in between. The type decides spacing, staking, pruning and picking labour.

Many Indian hybrids are sold as semi-determinate or indeterminate. TNAU describes its Tomato Hybrid CO 3 and CO 4 as semi-determinate, and its polyhouse page uses an indeterminate hybrid. A farmer with a labour shortage may do better with determinate types, or with fewer stems on indeterminate plants.

A practical rule: choose determinate for open-field, low-labour plots aimed at a single glut-and-sell window, and choose indeterminate for staked, drip-fed plots where you can pick every 2 to 3 days for months.

Recommended choices depend on your state, so start with the state agricultural university list. As examples, TNAU lists PKM 1, Paiyur 1, COTH 1, COTH 2 and its CO 3 and CO 4 hybrids, while the Assam package lists Punjab Chhuhara, Pusa Ruby, Arka Abha and Arka Alok, the last two resistant to bacterial wilt.

These yields come from research stations and state packages, not from your field. TNAU itself gives two different yield figures for the same CO 3 hybrid (96.2 t/ha on one page and about 30 t/ha rainfed on another), which shows how much management and water change the result. Many private hybrids are sold in India, but the opened university pages do not rate them, so ask the seller for the resistance claims in writing and check at least one nearby grower who used the same hybrid in the same season.

If leaf curl virus is common where you farm, pick a variety or hybrid sold as tolerant. Our post on integrated disease management in chilli explains the same whitefly-virus cycle in a sister crop.

There is no single national date. Tomato can be grown over many months, but each region has a safe window that avoids peak heat, frost and the worst of leaf curl. Use your state agricultural university or KVK schedule. The sourced examples below come from TNAU, Assam Agricultural University and ICAR-CIAH.

Work back from the safe transplanting date and sow the nursery about 4 weeks earlier. Planting into cooler months, as the Assam hill-zone note shows, can cut leaf curl pressure. A crop transplanted into the monsoon meets blight and whitefly, so it needs better drainage and closer scouting. Check your own farm records for the months when whitefly and blight hit hardest.

Raise seedlings on a raised bed 1 m wide and 10 to 15 cm high, or in pro-trays filled with cocopeat, and transplant at about 25 days. TNAU gives seed rates of 300 to 350 g/ha for varieties and 100 to 150 g/ha for hybrids. Cover the nursery with fine net to keep out whitefly.

• Seed treatment. TNAU says to coat seed with Trichoderma viride at 4 g per kg with rice kanji, 24 hours before sowing. If you use a chemical seed treatment, choose one registered for tomato on the CIB&RC list and follow the label dose.
• Bed. Soil mix of 2 parts fine red earth, 1 part sand and 1 part FYM. Lines 10 to 15 cm apart. Cover seed with fine sand or powdered FYM, mulch with paddy straw and water with a rose can. Use clean or solarised soil to lower the risk of damping off.
• Pro-tray option. About 1.2 kg of cocopeat fills one 98-cell tray. TNAU mixes 300 kg cocopeat with 5 kg neem cake and 1 kg each of Azospirillum and Phosphobacteria. One seed per cell. Drench with 19:19:19 at 0.3 percent (3 g per litre) at 18 days after sowing.
• Age at transplanting. TNAU shows 25 day seedlings; its organic farming page says 4 to 5 weeks, when seedlings are 7.5 to 10 cm tall with a sturdy stem.
• Protection. An ICAR-CIAH article describes covering nursery beds with transparent polythene or a 40 mesh insect-proof nylon net in hot arid conditions. Net covering is also the main step against whitefly and Tuta in the nursery.

Seedlings are cheap to protect and costly to replace. If damping off appears (seedlings rot or topple), TNAU lists seed treatment with Trichoderma asperellum at 4 g per kg or Bacillus subtilis at 10 g per kg. Prevent standing water by keeping the raised bed at about 15 cm. For any chemical drench, use only a product registered for tomato on the CIB&RC list at label dose.

Prepare a fine tilth, apply FYM at least 15 days before transplanting, and plant at the spacing for your growth habit. The Assam package uses 60 x 45 cm for determinate and 75 x 30 cm for indeterminate types. TNAU uses a paired row of 90 x 60 x 60 cm with drip, about 23,334 seedlings per hectare.

For the drip layout, TNAU describes laterals 1.5 m apart, drippers at 60 cm (4 litres per hour) or 50 cm (3.5 litres per hour), raised beds 120 cm wide at 30 cm intervals with the lateral in the centre of each bed, and wetting the beds through the drip for 8 to 12 hours before planting. Gap filling is on day 7 after transplanting.

For weeds, TNAU lists a pre-emergence herbicide after planting plus one hand weeding at 30 days. Use only a herbicide registered for tomato on the CIB&RC list, at label dose, or use mulch instead as covered in the next section.

Stake at about 30 days after planting with 1 to 1.5 m stakes and remove side branches up to 20 cm from the ground. TNAU says this helps spraying and harvesting, reduces buckeye rot and improves yield and quality. Indeterminate types need stronger support and regular tying than determinate types.

• Staking. Put a stake or a string line beside every plant or pair, and tie the main stem loosely every 20 to 25 cm of growth. Tying too tight cuts the stem as it thickens. This tying advice is practical, not from TNAU.
• Pruning. For indeterminate plants, remove the lowest branches and manage suckers. Keeping one or two main stems is a common choice; with a labour shortage, fewer cuts mean less work. For determinate plants, remove only the growth that touches the soil.
• Mulch. TNAU lists black LDPE mulch, 25 micron, with both ends buried 10 cm deep, as a weed control option. In a hot, dry spell, mulch also evens out soil moisture, which helps with cracking and blossom end rot. Our post on mulching types and depth compares plastic and organic options.

TNAU's drip schedule for tomato is 200:250:250 kg N:P:K per hectare, with 75 percent of the phosphate applied as basal and the rest, plus nitrogen and potash, split over four stages across about 150 days. The Assam package for rainfed fields is FYM 10 t, N 75, P2O5 60 and K2O 60 kg per hectare.

The page also lists FYM at 25 t/ha before the last ploughing and 2 kg per hectare each of Azospirillum and Phosphobacteria mixed with 50 kg of FYM. A footnote on the page gives basal quantities, but it does not explain how they relate to the superphosphate dose, so confirm the basal split with your KVK before buying. The TNAU fertigation page is dated June 2023.

Foliar sprays from TNAU's cultural practices page: zinc sulphate 0.5 percent three times at 10 day intervals from 40 days after planting; 19:19:19 plus micronutrient mix at 1 percent at 60 days; boric acid 0.3 percent at flowering and again 10 days later. For the protected-cultivation crop, TNAU shows N sprays at 2 ml per litre at 30, 55 and 75 days after planting.

If you farm without drip, the Assam package says to apply half the nitrogen and all the FYM, phosphate and potash basally, and top dress the remaining nitrogen in one or two splits. It also lists a foliar urea program (about 9.7 kg urea in 1,000 litres at day 30, 14.1 kg in 1,500 litres at day 40, and 19.3 kg in 2,000 litres at day 50, per hectare) in place of part of the basal nitrogen. Buying water-soluble grades for drip is covered in our water-soluble fertilizer buying guide.

For soil-building before planting, Katyayani Tomato Unnati Organic Kit is a bio-input set. Its page lists NPK Bio Consortia at 1.5 to 2 kg per acre mixed with compost during soil preparation, Bhumiraja (VAM) at 4 to 8 kg per acre broadcast with manure, and Humic plus Fulvic Acid at 2 kg per acre through drip. The page does not say how many acres one kit covers, so work out the area from the per-acre doses.

Irrigate right after transplanting and then at 10 to 15 day intervals in rainfed or furrow systems, depending on soil, as the Assam package says. Under drip, TNAU feeds the crop through the lines in stages. The key is steady moisture. Swings between dry and wet cause blossom end rot and cracking.

The TNAU polyhouse page uses an irrigation regime of 20 kPa for the rainy-season protected crop, which means keeping the soil moist rather than wet. For open-field crops, the pages opened do not give a litre figure, so base the schedule on soil, crop stage and weather.

• Do not let beds dry out, then flood them. That cycle is what cracks fruit and causes end rot.
• Use mulch. It holds moisture and lowers swings between irrigations.
• Cut water around heavy rain. Waterlogged beds invite wilt and late blight. See the disease sections below.
• Cut back nitrogen and water together if you see only leaf growth. TNAU also notes using nitrogen and irrigation judiciously as part of whitefly management.

Blossom end rot is a dark, sunken patch at the flower end of the fruit. It happens when calcium does not reach the growing fruit, usually because of uneven watering, not because the soil lacks calcium. It is a physiological problem, not an infection. Even moisture and a soil test are the first fixes.

The Ohio State University Extension page says calcium moves mostly to the leaves, especially under moisture stress, high air temperature and high humidity, so the fruit misses out while it is expanding fast. Its prevention list is to mulch around the base, water consistently while fruit develops and supply calcium through fertiliser as needed. The same OSU note frames it as a delivery problem rather than a disease.

If a test shows low calcium, Katyayani Calcium Nitrate (18.8 percent calcium, 15.5 percent nitrogen on the page) lists blossom end rot among the disorders it targets. Its only listed method is soil application at 3 to 5 kg per acre, and the page gives no tomato-specific timing, so count its nitrogen when you plan your urea. Fix the water pattern first. Calcium does not help if watering stays uneven.

Fruit cracks when the plant takes up a lot of water quickly after a dry spell, such as heavy irrigation or rain on dry soil. The fruit swells faster than the skin can stretch and splits. Steady soil moisture, mulch and picking at the right stage reduce cracking.

The Ohio State page gives the cause as quick water uptake after dry soil is heavily watered or rained on, and the fix as keeping soil consistently moist with mulch. The Assam package says the variety Punjab Kesri shows no fruit cracking. Ask for crack tolerance when you buy seed if your area has sudden monsoon showers.

• Irrigate lightly and often in a hot spell, not once heavily.
• Pick before a forecast heavy rain if the fruit is near ripe. This is practical advice, not from a university page.
• Keep leaf cover on fruit. Heavy leaf removal exposes fruit to sun, which raises damage.

Fruit borer (Helicoverpa armigera) feeds on tender leaves when young and bores round holes into fruit when older. Start with sanitation, a marigold trap crop and pheromone traps, add Trichogramma and HaNPV, and use a spray only if it is registered for tomato on the CIB&RC list. Destroy bored fruit.

TNAU lists these non-chemical steps: collect and destroy infected fruit and grown larvae; plant 40-day-old African marigold with 25-day-old tomato seedlings in a 1:16 row ratio; set pheromone traps with Helilure at 12 per hectare; release Trichogramma pretiosum at 1 lakh per hectare every 7 days from flower initiation; spray HaNPV at 1.5 x 10^12 POBs per hectare; and evening sprays of Bacillus thuringiensis at 2 g per litre or azadirachtin 1 percent EC at 2 ml per litre. The page gives no economic threshold.

If scouting shows damage beyond what these steps hold, use only an insecticide registered for tomato on the CIB&RC list, at the label dose, and observe the pre-harvest interval. Rotate groups rather than repeating one. Our post on biopesticides, types and examples explains how HaNPV, Bt and neem fit a rotation.

Tuta absoluta is a small moth whose larvae mine leaves, stems and fruit. Because larvae feed inside the leaf, sprays alone fail. Combine clean nurseries, pheromone traps, removal of infested plants and, only if needed, a spray registered for tomato on the CIB&RC list. Avoid solanaceous crops after tomato.

Start with seedlings: raise them under fine net and transplant only healthy ones. In the field, scout the underside of leaves for mines every 3 to 4 days in the first weeks. This scouting interval is practical advice, not from a university page. Pull out and destroy badly mined plants and fruit instead of leaving them in the plot.

TNAU's pinworm page lists mining of leaves and stems and pinholes on fruit, then says collect and destroy affected plants and fruit, avoid planting solanaceous crops after tomato, transplant healthy seedlings, and use pheromone traps for the adult males. For any spray, use only an insecticide registered for tomato on the CIB&RC list, at label dose and pre-harvest interval, and rotate groups.

Pheromone lures differ by maker, so follow the trap density and lure-change interval printed on the lure pack. Traps catch males and tell you when moths arrive. They do not control the pest alone.

For a leaf miner spray plan, the Katyayani Leaf Miner Protection Kit pairs spinosad 45 SC and activated neem oil, and its page lists tomato among the crops. The page gives no spray timing or interval and does not name Tuta absoluta, so follow the pack label and rotate chemistry.

Tomato leaf curl is a virus spread by whitefly. Infected plants stunt and leaves curl and crinkle, with no cure once infected. Control the vector: protected nursery, yellow sticky traps, weed removal, barrier crops and tolerant varieties. Uproot diseased plants early and rotate insecticide groups.

The TNAU leaf curl page lists stunting, downward rolling and crinkling, tough brittle older leaves, shortened internodes and a bushy look. Integrated management: raise nurseries under protection; plant sorghum, maize or bajra as a barrier crop; use disease-free seed; yellow sticky traps at 5 per acre; remove the weed host Abutilon indicum; and, if whitefly builds up, spray only an insecticide registered for tomato on the CIB&RC list at label dose and pre-harvest interval.

TNAU's whitefly page adds uprooting leaf-curl plants and using nitrogen and irrigation judiciously. Older university pages can list products whose registration has since changed, so do not copy a product name or dose from an old page. Check the current CIB&RC list.

• Choose tolerant material. TNAU lists its CO 3 hybrid and COTH 2 as resistant to leaf curl virus.
• Time planting. The Assam package suggests October planting in the hill zone to escape leaf curl.
• Scout every 3 to 4 days in the first 6 weeks, since early infection hurts yield most. That is practical advice, not from TNAU.

TNAU also lists tomato spotted wilt, which is spread by thrips (not whitefly) and shows as rings on leaves, bronzing of young leaves, tip die-back and yellow-ringed fruit. Its advice is to transplant healthy seedlings, rogue infected plants up to 45 days after planting and use sorghum, maize or bajra barrier crops. Do not mistake it for leaf curl, because the vector and the spray plan differ.

Early blight (Alternaria solani) shows brown spots with rings, like a target, and a yellow edge on leaves, and ringed brown rot at the stem end of fruit. Clean up debris, rotate crops, treat seed with Trichoderma and, at the first spots, use only a fungicide registered for tomato on the CIB&RC list, rotating groups.

TNAU's early blight page lists the cultural steps: remove and destroy crop debris, rotate crops and treat seed with Trichoderma asperellum at 4 g per kg. For sprays, use the label dose, interval and pre-harvest interval of a product registered for tomato. Do not copy a dose from an old page.

The Katyayani All Vegetable Disease and Yield Kit lists early blight in tomato on its page for the Dr. Zole fungicide. The page also names paddy, wheat and onion targets, so read the physical pack and follow its dose and interval for tomato.

Spraying alone is not enough. Early blight builds in dense, wet canopies. Staking, mulch to stop soil splash and drip instead of overhead water all lower pressure.

Late blight (Phytophthora infestans) spreads fast in cool, humid, wet weather and turns leaves into purple-brown oily patches and fruit into firm brown areas. It cannot be cured once it shows. Apply a protectant before infection in wet spells, avoid overhead water and remove infected plants quickly.

Late blight spreads when cool, humid, wet weather lasts for hours, so a protectant has to be on the leaf before infection, not after symptoms show. Do not lean on a single product; rotate fungicide groups as the label advises, and check your state advisory in wet spells.

From the Assam package, the spray practice: match water volume to crop size (600 litres per hectare in month one, 800 in month two and 1,000 in month three), add a sticker in rainy weather, and wet the underside of the leaf. For the fungicide itself, use only a product registered for tomato late blight on the CIB&RC list, at label dose and interval.

Potato and tomato share this disease, and blight in a nearby potato crop is a warning for your tomatoes. Our post on potato late blight control and prevention has a weather-based calendar that carries over to tomato.

Wilting plants need a quick check: Fusarium wilt starts with yellow lower leaves and a brown vascular ring; bacterial wilt wilts the whole plant rapidly and oozes white bacteria from a cut stem. Rotation, resistant varieties, clean seedlings and drainage matter most, because there is no field cure.

The table draws on TNAU's Fusarium wilt and bacterial wilt pages, and the Assam package for resistant varieties. For any chemical drench, use only a product registered for tomato on the CIB&RC list at label dose.

To suppress soil-borne fungi before planting, the Tomato Unnati Organic Kit includes Trichoderma viride (label: 1 to 2 kg per acre as a soil drench at planting, aimed at wilt, damping off and root rot). Treat that as prevention, not rescue, and keep rotation and drainage in place.

Tomato starts bearing from about 55 to 60 days after transplanting for early determinate types, and about 110 to 145 days from transplanting for hybrids. Picking runs for weeks. Yields range from 12 to 16 t per acre for varieties to 32 to 38 t per acre for protected hybrids, per TNAU.

The spread is large for a reason. Research-station and protected yields come from tight management, drip and tall indeterminate hybrids. The Raipur figure comes from real farms a decade ago. Plan with the lower end and treat the top end as a target, not a promise.

TNAU's fertigation schedule runs picking on alternate days for 80 days (stage 4). The polyhouse page gives 110 to 115 days from transplanting for the indeterminate hybrid, which is 135 to 140 days from sowing. Pick at the maturity or colour stage that suits your buyer and the distance to market, and follow the grading your mandi or buyer uses.

• Pick on a fixed schedule. Every 2 to 3 days in peak, in the cool morning, into shaded crates.
• Keep a harvest log by picking. It shows the yield curve and tells you if a stress cut fruit set.
• Do not stack crates in the sun. Heat and pressure in the field bring on rot in the market.

This is a labelled sample study, not a current benchmark. The Raipur (Chhattisgarh) study of sample farms in 2014-15 gave Rs 29,233 per hectare cost (about Rs 11,830 per acre), 127 quintals per hectare yield and Rs 63,971 net income per hectare (about Rs 25,890 per acre). Use its split below as a guide, then fill in the sheet after it with your own figures.

In the Plant Archives paper, labour was over 60 percent of cost and plant protection only about 2.5 percent. That reflects open-field tomato under the management of that study. A staked, drip-fed hybrid crop adds stakes, twine, mulch, drip lines, hybrid seed and more sprays, so its cost split differs. The Assam package quotes a benefit cost ratio of 6.41 with a yield of 350 to 400 q/ha, but it does not say what costs go into it.

Dividing the study's output value (Rs 93,205) by its yield (127.16 q) gives about Rs 733 per quintal, or Rs 7.33 per kg, realised by those farmers in 2014-15. For your own plan, take the mandi rate for your market and month from Agmarknet.

Price risk is the real cost. Tomato prices can swing hard inside one season, so staggered planting, grading and a buyer agreed in advance matter as much as yield. For a sister crop with a fuller per-acre breakdown, see our post on potato farming cost per acre.

Protected cultivation raises yield per acre and lets you plant outside the open-field window, but it needs capital and skill. TNAU reports 80 to 95 t per hectare for protected hybrids against 30 to 40 t for varieties. Run the numbers on structure cost, subsidy and your market before you commit.

TNAU's protected cultivation page describes 35 percent shade net for the summer crop and an indeterminate hybrid in a polyhouse for the rainy season, on a medium of FYM, composted coir pith and sand in a 2:1:1 ratio, with black polyethylene mulch (50 micron) and fertigation of 250 kg each of N, P and K per hectare. The paired row spacing is 80 x 40 x 60 cm. Duration is 110 to 115 days from transplanting.

The page does not give structure cost or returns. Our posts on greenhouse farming cost, types and profit cover those, and net or polyhouse structures also help keep whitefly and Tuta out of the crop.

Bio-inputs work best as a base layer in the soil and nursery, not as a rescue. They build roots and soil life, add calcium from the soil store and suppress soil fungi. Pair them with a university fertiliser schedule and proper water management. They do not replace spraying where a pest outbreak has started.

Two Katyayani combos are built around tomato. The Tomato Unnati Organic Kit is for soil preparation and planting, listing NPK Bio Consortia, Trichoderma viride, Bhumiraja (VAM), Metarhizium anisopliae, Humic plus Fulvic Acid and Calcium Solubilizing Bacteria. Its label doses are per acre: Trichoderma 1 to 2 kg, Metarhizium 1 to 2 kg near the root zone for grubs, cutworms and root weevils, and Calcium Solubilizing Bacteria at 5 to 10 ml per litre every 10 to 15 days.

The Tomato Unnati Drip Kit is a liquid set for drip: Bio NPK, Trichoderma viride, K-Raja (VAM), Metarhizium, Seaweed Extract, Mix Micronutrient and Calcium Solubilizing Bacteria. The page gives doses per litre for some parts (for example Bio NPK 2 to 3 ml per litre every 10 to 15 days, Seaweed Extract 2 ml per litre every 20 days) but no full-season plan or area covered, so follow the pack label for the timing of the other parts.

Do not stack the organic kit and the drip kit on the same acre without checking, since both contain Trichoderma, Metarhizium and Calcium Solubilizing Bacteria. For other vegetable kits, see the vegetable combo collection; the page does not list a tomato-named kit among its items, so pick what matches the problem you have, not the name.

Conclusion

Tomato rewards growers who decide the basics early and keep them steady. Choose determinate or indeterminate to match your labour, raise net-covered seedlings for about 25 days, plant at 60 x 45 cm or 75 x 30 cm, stake at 30 days, and feed in stages using the TNAU schedule as a guide. Keep water even to prevent blossom end rot and cracking, scout weekly for fruit borer, Tuta absoluta, whitefly and leaf curl, and spray blight before the weather turns wet. Cost data is thin, so keep your own sheet from day one.
