The Seasonal Calendar of Karnataka Pulses and Oilseeds
When is each Karnataka pulse and oilseed at peak quality? A month-by-month answer from a 40-year-old trading house at APMC Yard, Bandipalya, Mysuru — covering sesame, neem seeds, tamarind, horse gram, loba, groundnut, and honge seeds (pongamia) across the kharif and rabi cycles. If you are planning a full year of procurement from Karnataka and want to know when to forward-book, when to draw on stored lots, and when to stay patient, this is the calendar to keep at hand.
Two seasons, eight commodities
Karnataka's agricultural year is governed by two cropping seasons, and every buyer planning procurement here needs to have them fixed in mind before discussing price or availability with any yard trader.
- Kharif (June to October)
- The monsoon-fed season. Sowing happens in June and July once the southwest monsoon arrives over Karnataka. Harvests come in September through November depending on crop and geography. Kharif produces loba, sesame, and the first flush of groundnut. Arrival quality at the yard is highest immediately post-harvest, when moisture levels are still manageable and before long storage begins.
- Rabi (October to March)
- The winter crop, grown on residual soil moisture or under limited irrigation. Sowing follows the kharif harvest. Rabi produces horse gram, the second groundnut flush (in irrigated tracts), and — later — the collections of tamarind and honge. Quality varies more with rabi lots because the crop is more dependent on local irrigation decisions; in deficit rainfall years, yields drop and lot uniformity suffers.
Outside these two formal seasons sit the tree-borne collections: neem seeds (harvested when neem trees shed their fruit, May to July) and tamarind (the pod-bearing season runs January to April). These operate on their own cycle, independent of the ploughing calendar, though a poor monsoon will still affect neem fruit set and tamarind pod fill the following season.
Month-by-month availability: the full calendar
The table below draws on our experience at KVM & Co., Mysore across four decades of yard trading. "Peak Availability" means the months when fresh-lot arrivals are highest and quality — moisture, uniformity, purity — is at its best. "Off-Season" means the period when supply runs on stored carry-over lots only; quality can still be acceptable but you will pay a storage premium and accept older grain.
| Produce | Peak Availability | Off-Season | Typical Quality Notes | Lead Time Considerations |
|---|---|---|---|---|
| Sesame (til) | October – January | April – June | Kharif harvest; moisture 6–8% at fresh arrival. White varieties from Chamrajnagar and Nanjangud taluks. Bold seed, good oil content in peak lots. | Book in November–December for Jan–Mar delivery. By February, a portion of available stock is already 3–4 months old. |
| Neem seeds | May – July | August – April | Collection-season commodity; availability concentrated over 10–12 weeks. Oil content peaks in June–July collections. Older stored lots lose extractable oil yield. | Advance expression of interest by April. Season is short; single-window procurement. No second flush. |
| Tamarind (fruit) | January – April | May – December | Pod-bearing season peaks Feb–March. Tartaric acid content and pulp-to-seed ratio are best in fresh Feb–Mar collections. Quality drops sharply in lots held beyond June without proper cold storage. | Year-round availability is possible from cold-storage operators, but quality and price diverge significantly from fresh-season lots. Plan seasonal forward-booking if consistency matters. |
| Tamarind seeds | February – May | June – January | A by-product of tamarind pod processing; arrives 4–6 weeks after peak fruit harvest. Used in industrial starch and tannin applications. Germination rate and xyloglucan content are highest in fresh lots. | Dependent on tamarind pod processing timelines. If a buyer sources both tamarind and its seeds, coordinating the two procurement windows simplifies logistics considerably. |
| Horse gram (hurali) | December – March | July – September | Rabi crop, rain-fed in dry tracts of Mysuru, Chamarajanagara, and Hassan. Hard seed coat; lower moisture sensitivity than loba. Bold, uniform lots appear December–January. | Rainfall adequacy in September–October determines yield; watch IMD seasonal forecasts for the northeast monsoon. Procurement windows that run to March capture the bulk without storage risk. |
| Loba (alsande / cowpea) | June – September | January – March | Kharif pulse; early arrivals in late June from fast-maturing varieties. Moisture content at arrival can be 12–14%; insist on drying confirmation before accepting large lots. Colour retention and seed coat integrity decline with prolonged storage. | Procurement should be wrapped up by October–November, before stored lots begin to show moisture migration. Kharif loba held into the new year is typically discounted 8–12% from fresh-season price. |
| Groundnut (shengdana) | July – December | April – May | Dual-season commodity: kharif crop (June sowing, Sep–Oct harvest) from Kolar, Tumkur, and Chitradurga; rabi irrigated crop (Oct sowing, Jan–Feb harvest) from coastal-adjacent tracts. Peak uniformity at each harvest; transition months (Nov–Dec) see both new-season and stored kharif lots in the yard simultaneously. | Moisture is the single biggest risk variable. APMC arrivals in September carry 10–12% moisture; properly dried lots stabilise at 7–8%. Check drying status on every lot before committing. See our note on groundnut harvest volatility. |
| Honge seeds (pongamia) | January – April | September – November | Tree-borne collection; pods shed January–March after the tree loses its leaves. Oil content (karanj oil) is highest in January–February collections. Industrial buyers (biodiesel, soap, pesticide) should target this window. | Collection is labour-intensive and fragmented; no organised procurement structure comparable to APMC arrivals for field crops. Allow additional lead time for aggregation from village-level collectors. |
What actually moves the seasons
The southwest monsoon is the master variable
Most kharif crops in Karnataka depend on the southwest monsoon arriving by the first week of June over coastal Karnataka and the second week over the Mysuru plateau. A delayed onset — even by two weeks — shifts the entire kharif arrival calendar forward. In our experience at the APMC Yard, a late onset year will push sesame arrivals from the usual October start to late October or even November, compressing the peak-quality procurement window significantly. Buyers monitoring procurement timelines should track the India Meteorological Department seasonal forecast from April onwards, not just during the monsoon itself.
The northeast monsoon matters for rabi
Horse gram and some rabi groundnut in Karnataka depend on the northeast monsoon (October–December) for soil moisture at sowing time. A deficit northeast monsoon — more common in La Niña years — can reduce horse gram yield and lot size from December harvests. The Karnataka State Department of Agriculture publishes district-level crop condition reports that we find useful for early-season assessment.
Tree-borne collections are weather-lagged by one full year
Neem seed collection volumes and honge seed yields respond to the previous year's monsoon, not the current one. Good fruit set on neem and pongamia trees happens in the monsoon months; you collect the resulting seeds six to nine months later. This means a drought year in Karnataka shows up in neem and honge procurement as a supply constraint the following spring — a lag that catches buyers by surprise if they are not tracking it.
Year-to-year variability is real and should be built into planning
Peak quality versus end-of-season: the honest trade-off
Every commodity has a point in its seasonal arc where quality is highest and a later point where it is lowest. Buyers who understand this trade-off can make better decisions than those who simply track market price.
Peak-season lots: what you gain and what you pay
- Fresh arrival, low moisture. Sesame at 6–7%, groundnut at 7–8%, loba at 10–11% after yard drying — these are the benchmarks. Fresh-season lots arrive within weeks of harvest and have not yet had time to absorb ambient humidity.
- Higher uniformity. Freshly threshed and cleaned lots have more consistent seed size, colour, and purity than carry-forward lots that have gone through multiple handlings.
- Higher price. Demand is concentrated in the harvest window. Traders are buying actively; competition drives prices up. For price-sensitive buyers, this is a real cost.
- Shorter negotiation window. Peak-season lots move quickly at the APMC Yard. Buyers who delay tend to find the best-quality lots already committed to forward contracts.
End-of-season lots: what you gain and what you accept
- Lower price. Traders holding stored inventory are motivated sellers in the off-season. Discounts of 8–15% versus peak-season price are common, depending on commodity and how far into the off-season you are purchasing.
- Older grain. A lot sold in May that was harvested in October is now seven months old. Even in well-managed storage, oil content will have dropped, colour may have shifted, and there is some risk of insect pressure depending on storage conditions.
- Moisture creep. Any lot held through the pre-monsoon months (April–May) in poorly sealed storage will have absorbed humidity. Always insist on a moisture reading at time of purchase, not just at harvest. Check AGMARKNET daily price and arrival data — large arrival spikes outside the normal season often indicate distress liquidation of stored lots.
"The best lot we ever traded was not the cheapest lot. It was the one that arrived exactly when our buyer needed it, at the moisture level they had specified, with no re-handling required. Timing is quality."
Planning a full year of procurement
For buyers who need continuous supply across twelve months — food processors, exporters, large agri-commodity traders — the standard approach is a combination of forward-booking in peak windows and planned drawdown from stored lots in the off-season. Here is how we see it working in practice from our position at KVM & Co., Mysore.
Forward-book in peak months
The peak-quality window is also the forward-booking window. A buyer who agrees on a price in October for sesame to be delivered through March is locking in both quality and a fixed lot — and typically achieves a better price than a spot buyer in December when the yard is busiest. Forward contracts also give the seller confidence to hold the lot without selling into the spot market; this is meaningful for commodities like neem seeds where the entire season runs for only ten to twelve weeks.
Draw from stored lots in the off-season
For bulk industrial uses where quality parameters are well-defined and tested on receipt, off-season stored lots can be acceptable — especially if the buyer can verify storage conditions and has a moisture threshold written into the contract. The key is written specification: moisture at delivery, purity, absence of adulterants or insect damage. Verbal agreements on stored lots create disputes; written lot inspection notes prevent them.
Watch the weather before you commit
Do not forward-book in bulk before the southwest monsoon performance is clear. If you are planning procurement for a kharif commodity — sesame, loba, early groundnut — an expression of interest in May is sensible, but hard commitment should wait until the July IMD monsoon progress report indicates normal or above-normal progression over Karnataka. A deficit monsoon will push prices up and compress lot quality. See the IMD extended range forecast for a lead indicator.
Five rules of thumb for Karnataka commodity buyers
- Map your commodity to its season before you map it to a price. Buyers who chase the lowest spot price without understanding where a commodity sits in its seasonal cycle routinely end up with older, higher-moisture, or more variable-quality lots than buyers who pay a modest premium at the right time.
- Neem and honge are single-window commodities. Unlike field crops that have carry-forward inventory, these tree-borne collections have a sharp and non-repeating season each year. Miss it, and you pay a significant premium for the thin remaining stock or wait twelve months. Arrive early and express interest in advance.
- Write moisture into every contract. The single most common source of quality disputes in pulse and oilseed trade is unspecified moisture at delivery. Specify acceptable moisture percentage, the instrument used to measure it, and whether re-drying cost falls on buyer or seller.
- Track IMD and AGMARKNET from April. The AGMARKNET daily arrivals and price data shows you real-time arrival volumes at Karnataka mandis; a sudden drop in arrivals mid-season is usually a signal of either a weather disruption or a hold-back by farmers. Neither is good for a buyer on a tight timeline.
- Build in four to six weeks of flexibility on either side of the peak window. Monsoon variability, transport disruptions, and APMC yard logistics mean that even well-planned procurement can slip by a fortnight. Buyers with hard delivery deadlines and no buffer consistently pay a premium to secure last-minute lots or air-freight substitutes.
