Onion, tomato and potato are the three vegetables almost every food manufacturer buys – for soups, sauces, seasonings, snacks and ready meals. In India, their prices rarely move together, and each follows its own seasonal pattern. In October 2026, onion prices were nearly double last year's level, while tomato and potato prices were lower than a year earlier.
For buyers, that means the cost of a recipe can change sharply from one quarter to the next. This guide sets out a simple price calendar for the three crops and explains how dehydrated vegetables help you buy at the right time and avoid the peaks.
Short answer: in India, tomato and potato prices usually rise between May and July, onion prices tend to climb from August to October as stored crops run low, and all three usually ease from December to April when new harvests arrive. Because dehydrated vegetables keep for many months in sealed packs, you can buy them when supply is good and hold stock through the expensive months.
What is happening to vegetable prices in 2026?
This year shows how differently the three crops behave. On 18 August 2026, the average wholesale onion price in India was about ₹2,898 per quintal, 118% higher than a year earlier, according to Agmarknet data reported by FreshPlaza. On the same day, tomato prices were about 58% lower and potato prices about 31% lower than in 2025.
By late October, AgroSpectrum India reported that onion prices were still nearly double their level of a year ago. Earlier in the year, tomato had its own spike: in June 2026, wholesale tomato prices were almost 59% higher than a year before.
The onion, tomato and potato price calendar
The exact numbers change every year, but the pattern repeats. Analysis of ten years of wholesale data by CMIE, reported by Outlook Business, found that tomato, onion and potato prices consistently rose between May and July and fell from December to mid-April, when kharif and rabi arrivals came to market.
| Months | Onion | Tomato | Potato |
|---|---|---|---|
| December – April | Usually easing as new kharif and rabi crops arrive | Usually easing | Lowest around the main harvest |
| May – July | Supported by stored rabi onion | Often rising – heat and planting delays hit supply | Often rising as cold-store stocks are used |
| August – October | Often the peak – stored stocks run low before kharif arrivals | Can swing sharply with monsoon damage | Usually steady |
| November | Easing once kharif arrivals pick up | Mixed | Steady to easing |
Weather can shift the calendar by weeks – a late monsoon, a heatwave or storage losses can all move a peak earlier or later. Even so, the broad seasons are reliable enough to plan purchases.
Why each crop follows its own cycle
- Onion: most of India's onion is harvested in the rabi season and stored for months. As stored stocks shrink and lose quality from August, prices rise until the kharif crop arrives.
- Tomato: tomato is highly perishable and cannot be stored, so prices react quickly to heat, rain and planting delays – especially in the summer and monsoon transitions.
- Potato: potato keeps well in cold storage, so its price is usually the most stable of the three, though it can rise in summer as stored stocks are used.
How dehydrated vegetables smooth out the peaks
Fresh vegetables force you to buy at whatever the market charges that week. Dehydrated vegetables change that, because the water – and the perishability – is removed at the source:
- Buy in the low season: sealed packs store for months, so you can book volumes when fresh supply is plentiful.
- Lower freight and storage: it takes about 8–10 kg of fresh onion to make 1 kg of dehydrated onion, so you ship and store far less weight.
- No cold chain: dehydrated vegetables need only a cool, dry store, not refrigeration.
- Consistent recipes: a fixed specification gives you the same colour, flavour and particle size in every batch.
Which dehydrated vegetables replace onion, tomato and potato?
| Fresh vegetable | Dehydrated forms | Typical uses |
|---|---|---|
| Onion | Flakes, chopped, minced, granules, powder | Seasonings, sauces, soups, snacks, ready meals |
| Tomato | Flakes, granules, powder | Soups, sauces and ketchup bases, noodle and snack seasonings |
| Potato | Flakes, dices, granules, powder | Instant mash, snacks, bakery, soups and ready meals |
How to plan your purchases
- Map how much onion, tomato and potato your recipes use each month.
- Decide which part of that volume can switch to dehydrated vegetables without changing the product.
- Book dehydrated stock ahead of the usual peaks – before May for tomato and potato, and before August for onion.
- Fix the specification in writing – form, size or mesh, moisture and packing – and ask for a certificate of analysis (COA) for each lot.
- Test samples in your own application before you place a bulk order.

Frequently asked questions
When are onion prices highest in India?
Onion prices usually climb from August to October, when stored rabi onion runs low and before the new kharif crop arrives. In 2026, wholesale onion prices in August were 118% higher than a year earlier.
When do tomato and potato prices rise?
Ten years of wholesale data show tomato and potato prices usually rise between May and July. Tomato is the most volatile because it cannot be stored.
Are dehydrated vegetables cheaper than fresh?
Per kilogram, dehydrated vegetables cost more because several kilograms of fresh produce go into each kilogram. Per unit of flavour and solids, however, they save freight, storage, peeling and waste, and they let you avoid buying fresh vegetables at peak prices.
How long do dehydrated vegetables last?
In sealed packaging, stored in a cool, dry place, dehydrated vegetables keep for many months; Frzex dehydrated onion, for example, has a typical shelf life of up to 24 months. Ask us for the shelf life of each product and form.
