About this variety
JS 335 is an early-duration, high-yielding soybean variety bred at JNKVV, Jabalpur, from the cross JS 78-77 × JS 71-05. It carries documented resistance to lodging and pod-shattering, letting it stand in the field through a delayed harvest better than many older releases. That is one reason it became the variety most responsible for Madhya Pradesh’s rise as India’s largest soybean-growing state, and it is still widely sown decades after release.
Should you pick this variety?
Pick JS 335 if your harvest often gets delayed by late rain and you want a variety every dealer, labourer and buyer in your area already knows. The JNKVV Jabalpur release from JS 78-77 × JS 71-05 resists lodging and pod-shattering, so a crop standing a few extra days loses less than a shatter-prone one. It takes 95–100 days for 15–18 q/ha, with moderate yellow mosaic virus resistance. It needs moisture at flowering and pod-fill, and does not suit land that waterlogs. For the same season length and more yield, choose JS 20-29; for an earlier harvest, JS 95-60.
Sowing & cultivation
- Sowing timeFirst fortnight of June in north-west India (PAU)
- Seed rate25–30 kg per acre (PAU)
- SpacingLines 45 cm apart with 4–5 cm between plants, seed sown 2.5–5.0 cm deep
- Sowing methodSow into good moisture, after a pre-sowing irrigation if the monsoon has not broken — heavy rain just after sowing wrecks soybean germination. Inoculate the seed with Bradyrhizobium, which lifts grain yield by up to 8%
- IrrigationWith good, well-spread rain the crop may need no irrigation at all; otherwise 3 or 4, and the one at pod filling is the one that pays (PAU)
- Fertilizer12.5 kg N and 32 kg P2O5 per acre at sowing — 28 kg urea with 200 kg single superphosphate. Drop the phosphorus to 24 kg P2O5 if the crop follows a well-fertilised wheat. A 2% urea spray at 60 and 75 days adds yield (PAU)
Advantages & considerations
Why farmers may choose it
- Bred-in resistance to lodging and pod-shattering, so a rain-delayed harvest costs less yield than it would with a shatter-prone variety
- The variety most responsible for Madhya Pradesh becoming India’s largest soybean-growing state — still one of the most familiar names to farmers, decades after release
Things to consider
- Needs more irrigation than shorter-duration varieties, with flowering and pod-fill the two stages where a moisture gap costs the most yield
- Suits fields that hold rainfall moisture well into the season — not a good fit for land prone to waterlogging
- Reported yield varies by source: the conservative field range is 15–18 q/ha, though some seed-trade pages report 25–30 q/ha under good management — treat the higher figure as a best case, not a guarantee

Why a rain-delayed harvest costs less on this variety
JS 335 carries bred-in resistance to lodging and pod shattering. In a season when the rain does not stop and the combine or the labour cannot get in for a week, that is money: a shatter-prone variety drops seed on the ground while this one holds the pods.
It is not a free pass. Pods that stay wet still discolour and the seed loses germination value, so harvest at the first dry window, thresh at the right moisture and dry the seed properly before bagging — especially if you plan to keep part of the lot for seed. On the other side, this variety needs more irrigation than the shorter-duration ones: flowering and pod-fill are the two stages where a moisture gap costs the most, so if you have one watering to spare, use it there.
Can you keep your own planting material?
This is an open-pollinated variety, so seed from a healthy crop of your own can be sown again. Keep seed only from disease-free plants, dry it properly, store it cool and dry, and bring in fresh certified seed every three to four years so the variety does not drift.

Frequently asked questions
Why is JS 335 still grown decades after its release?
Its resistance to lodging and pod-shattering means less yield is lost to a delayed or rain-hit harvest than with shatter-prone varieties, and its long track record across Madhya Pradesh has kept it a name farmers trust even as newer JS releases have arrived.
What does JS 335 seed look like, to check I have the right variety?
Purple flowers and yellow seed, with oil content around 17–19% and protein around 40–41% per seed-trade variety descriptions — a rough check that seed sold as JS 335 matches type.
Should I move from JS 335 to JS 20-29?
In most of Madhya Pradesh, yes — JS 20-29 fits the same 95–100 day window and gives 20–22 q/ha against 15–18. Stay with JS 335 if your worry is a rain-delayed harvest, since its lodging and shattering resistance is its strongest documented trait. Trying the new one on part of the field first costs you nothing.
Is JS 335 fine on land that waterlogs?
No. It suits fields that hold rainfall moisture well into the season, not land where water stands. On waterlogging-prone land, JS 20-29 is the better pick, since it was bred from the waterlogging-tolerant line JS 97-52.
When does JS 335 need water the most?
At flowering and at pod-fill. A moisture gap at either stage costs more yield than one at any other time, so if you have even one irrigation in hand, save it for those two stages.
What seed rate and sowing window does JS 335 need?
25–30 kg per acre (PAU), sown in the first fortnight of June in north-west India. Sow on a settled monsoon, not on the first shower: soybean germinating into a dry week after a false start is the commonest way a field is lost.
Will a rabi crop fit after JS 335?
Yes, it takes 95–100 days, so a June sowing is off the field through September and chana or wheat can follow on time. The risk is not the calendar but the rain: JS 335 is grown where the harvest may be rain-delayed, and a wet harvest is what eats the rabi window.
