Yielding five per cent more than any other variety on the 2021 BBRO Recommended List, BTS1915 leads the pack with an adjusted tonne yield of 108.1 per cent and a high sugar content of 17.7 per cent.
Bred by Betaseed and marketed by Limagrain UK, BTS1915 leads the Recommended List by a considerable amount – five per cent more than any other variety – and this is exceptional.
“Next on the list is KWS Evalotta yielding 103 per cent, followed by last year’s list topper KWS Kortessa at 101.9 per cent, so it’s clear to see the exceptional yield increase brought by BTS1915,” Limagrain’s sugar beet product manager, Ron Granger, said.
“We normally expect to see year on year yield advances of one to two per cent in yields, so BTS1915 is something quite special – and this is at a time when many other arable crop yields have plateaued.
“Nor is it a one year wonder performance” he added. “These extremely high yields have been consistent during the past three years that the variety has been in trials – so we’re confident in the variety’s ability to perform in different seasons and situations.
“We’re also in the fortunate position where sugar beet breeders are still able to push yields without compromising the sugar content – and this is reflected in BTS1915 with its very acceptable sugar percentage of 17.7.”
And it’s not all about the yield either.
“BTS1915 has excellent agronomic characteristics that make it a very useful variety on-farm,” Mr Granger said. “We recognise that varieties also need to establish well, have good bolting tolerance and robust disease resistances to succeed.
“However when BTS1915 is sown in the normal sowing window from mid-March onwards, it has shown excellent bolting tolerance, recording no bolters. This result has been consistent during the past three years, including data from 2019, which we know was a high year for bolting.
“However, it should be recognised that when BTS1915 is sown early, the variety might show excessive bolting as the Early Sown Bolter trials, conducted as part of the Recommended List trial series, demonstrate.
“The variety has the highest brown rust disease resistance rating on the Recommended List of 8.7, making it the first choice for late lifting where brown rust is potentially the key disease to control.”
BTS1915 provides an opportunity for growers who want to take the next step-up in yields, as in doing so they’re raising the bar in sugar beet production even higher – making themselves more resilient against the rising costs of producing a sugar beet crop.
According to figures from the John Nix Pocketbook for Farm Management 2019 edition, the additional benefits of this five per cent yield are significant in terms of profitability, irrespective of the crop being low, average or high yielding.
Increasing the yield by 5.0% on a crop yielding 66.5t/ha by 3.325t/ha brings a financial benefit of £67/ha. For a crop yielding 78t/ha, a 5% increase in yield of 3.9t/ha is worth £79.80/ha and on a crop yielding 89.5t/ha an extra 5% benefit in yield of 4.475t/ha is worth £91.51/ha. This is based on a 2020 beet price, on a three-year contract, at £20.45/t with no crown tare reduction.
