Sow the next crop into the standing one before it is harvested, so the new crop is already established the moment the field clears — one extra short-duration crop a year, without waiting for a fresh sowing window.
The quick decision panel — everything you need before reading a single paragraph further.
What actually changes on your farm once this is in place.
One extra short-duration crop a year from the same field, without a separate sowing window.
Uses the residual soil moisture from the standing crop instead of needing a fresh irrigation cycle to establish.
Skips a full round of land preparation between the two crops entirely.
Keeps the soil continuously covered by a growing crop, cutting the fallow period to nearly zero.
An early-established relay crop is less exposed to a late, compressed sowing window than a crop sown after full harvest.
Timely establishment inside the standing crop's moisture often out-yields the same crop sown late after clearing the field.
The practice broken into the steps you will actually follow, in order.
The standing crop should be roughly 2–3 weeks from harvest, with the canopy starting to thin.
Seed is hand-broadcast into the standing crop, relying on residual soil moisture to germinate.
The first crop's final irrigation is timed to also give the relay crop's seed enough moisture to establish.
Cut the first crop by hand or carefully by machine to avoid trampling the young relay seedlings underneath.
Once the field clears, the relay crop is already established and grows on as the sole crop.

Skipping land preparation is the main saving, but the bigger value is the 15–20 days of growing time the relay crop gains over sowing it after the field fully clears.
What farmers already using this technique typically measure.
15–20 days per cycle
Time Saved
1 additional short-duration harvest/year
Extra Crop

None needed for the relay crop — this step is what relay cropping is designed to skip.
The relay crop is broadcast into the standing crop roughly 2–3 weeks before its harvest.
This technique matters most here
The relay seedlings establish under a thinning canopy while the standing crop finishes maturing.
The standing crop is harvested here, and the relay crop takes over the field as the sole crop.
The relay crop, now well-established, continues to its own harvest on its normal timeline.

Relay cropping sows the next crop directly into the standing previous crop, roughly 2–3 weeks before it is harvested, so the new crop is already established the moment the field clears — instead of waiting to sow after the first crop is fully off the field.
It captures a growing window that would otherwise be lost to land preparation and a fresh sowing cycle, typically adding one extra short-duration crop a year and saving 15–20 days per cycle.
Mustard, lentil and moong are commonly relay-sown into standing paddy in eastern India, especially West Bengal, Bihar and Uttar Pradesh, where the paddy-to-rabi window is otherwise tight.
Intercropping grows two crops together for their full overlapping duration in planned rows. Relay cropping only overlaps briefly — the relay crop is sown just before the first crop's harvest, then grows on alone once the field clears.
No — the relay crop is typically hand-broadcast into the standing crop, which needs no machinery, though the standing crop's own harvest needs care to avoid damaging the young relay seedlings.
Roughly 2–3 weeks before the standing crop's harvest, when its canopy is starting to thin and soil moisture is still sufficient for the new seed to germinate — timing by canopy and moisture condition, not a fixed calendar date.
Yes, mainly from poor germination if soil moisture is too low at broadcasting time, or from seedling damage during the standing crop's harvest — both are manageable with careful timing and harvest technique.
Yes — it needs no machinery investment, just careful hand labour and correct timing, which makes it accessible to smallholders looking to add a crop cycle without extra land or equipment.
