The 2025 oilseed rape (OSR) harvest is shaping up to be one for the history books.
United Oilseeds expects UK OSR yields could surpass the long-standing record of 3.91 t/ha, set all the way back in 2011, and possibly even break through the 4.0 t/ha barrier. It predicts an average yield in the range of 3.95–4.0 t/ha, driven by improved genetics, a season of favourable weather, and reduced cabbage stem flea beetle pressure.
With a 227,000 ha harvested area, this step-up in productivity is remarkable. At 4.0 t/ha, the total crop is expected to be around 900,000 tonnes, well ahead of 700,000 tonnes from the long-term average of 3.11 t/ha. United Oilseeds calculates it is worth £100 million in additional UK GDP before even considering the knock-on benefits for the industry. It estimates the volume will require almost 7,000 extra lorry journeys, worth another £3 million to UK hauliers.
James Warner, managing director of United Oilseeds, said: “Our members are delighted to see yields lift this year, with the benefits of the OSR Reboot work now coming through. For those prepared to give the crop the focus it deserves, oilseed rape continues to prove why so many still regard it as the number one break crop.
“Lower flea beetle pressure, favourable growing conditions, and major advances from seed breeders have all played their part. We’re optimistic that this will encourage more growers to bring OSR back into their plans for the season ahead.”
With farmgate OSR prices holding steady in the £370 – £420 range and other commodity prices remaining flat, OSR will be the top gross-margin crop on many arable farms in 2025 the organisation believes.
On a yield of 4.0 t/ha at £400/t, OSR revenue hits £1,600/ha. Even accounting for higher variable costs, gross margins north of £1,000/ha are achievable, comfortably outpacing many wheat budgets this season. Stable prices and record-breaking yields mean the crop is delivering on all three OSR Reboot pillars while also rewarding growers financially.
Commenting on how the sector can capitalise on current momentum, James added: “For growers wanting practical tips, the joint AHDB and OSR Reboot Top 10 Management Strategies for Combatting CSFB are there for everyone — these principles have been agreed across the industry, and with collective effort in the field, we can ensure the future viability of this vital homegrown crop. With the considerable investment in the new CSFB Research+ project, it’s clear that the industry is fully committed to OSR’s future.”
