Lincolnshire grower Tim Lamyman has broken two world top-yielding grain records with a massive near-18t/ha winter wheat crop, at more than twice the UK average yield, while he has smashed his own record for winter barley with a whopping harvest of 16.21t/ha.
Mr Lamyman’s 17.96t/ha wheat crop topped previous world record holder Eric Watson, who harvested a 17.40t/ha crop in February 2020 on his South Island farm in New Zealand.
Mr Lamyman’s record at harvest 2022 came when UK wheat yields rose sharply despite a record heatwave and a prolonged drought.

The Lincolnshire Wolds grower also broke his own winter barley record with his crop of 16.21t/ha, beating his previous record harvest by a clear 2t/ha compared to his 2021 crop of 14.20t/ha on his fertile, chalky loam soils.
The record-breaking harvests surprised crop experts after such a dry spring, but his crops put down deep roots in a dry autumn, and his chalky soils acted like a sponge to preserve moisture to maintain strong plant growth through the spring and early summer drought.
“As long as we get enough moisture through the winter, a dry season is an advantage to us, and all our winning crops were on north-facing slopes, which allowed them to escape the worst of the heatwave,” he told Farmers Weekly.
Tweaked approach
His high input/high output system came up trumps as he tweaked his approach to add more crop nutrition late in the season to the ears of both his wheat and barley crops to keep them green throughout the summer, which helped push specific weights sharply higher.
The record-breaking wheat and barley crops earned him top gold awards in the annual Yield Enhancement Network (YEN) competition organised by crop consultants Adas, and he achieved a hat-trick of wins with a high-yielding crop of oilseed rape.
Over its 10 years, YEN has looked for record-making yields, but has also tried to understand what is behind top yields.
It has drawn entries from the UK and across northern Europe, while YEN competitions have started in eastern Canada and the Great Lakes region of North America.
Roger Sylvester-Bradley, head of crop performance at Adas and founder of YEN, said potential UK wheat yields ranged up to as high as 24t/ha.
Many crops at harvest 2022 were over 14t/ha, while the average wheat yield of some 200 YEN wheat entrants was 11.3t/ha.
“High yields of 14t/ha are possible almost everywhere as long as the soil holds sufficient water.
Most farmers seem to have increased yields so the crops must have had good rooting systems to cope with the dry weather,” he said.
Prof Sylvester-Bradley admitted they had underestimated how good some of the entrants’ soils were, and how deep the rooting systems had been, with some roots going down more than 2m to find moisture.
These high yields were possible with an adequate soil water supply, a good level of organic matter, soil phosphate, early sowing and low seed rates on narrow rows.
The frequency of applying inputs such as nitrogen was more important than the actual amount, he added.
World wheat yields
Mr Lamyman has tussled with mainly New Zealand growers for world-beating yields over the past decade, while his 2022 wheat triumph gave him three straight YEN wins.
He has now won gold for his wheat crops in seven out the 10 years the competition has been running.
The Lincolnshire grower first broke the world wheat yield record back in 2015 with a yield of 16.50t/ha.
He held it only for a few months before Rod Smith, in Northumberland, harvested a crop of 16.52t/ha on his farm near the Scottish Border, before he himself was pipped by Mr Watson.
The New Zealander, farming near Ashburton on the fertile silty soils of the Canterbury Plain just south-west of Christchurch, took back the record in February 2017 with a yield of 16.79t/ha,.
He then pushed ahead with a new world record crop of 17.40t/ha in February 2020.
Mr Lamyman, as well as the wheat and winter barley prizes, also picked up the top crop prize for oilseed rape at a yield of 8.98t/ha – itself one of the highest yields on record.
The top spring barley crop came from Hampshire, grown by Simon Budden at 11.02t/ha, with the winning oat crop from John Anderson of Caithness in the far north eastern tip of Scotland, while the best quality milling wheat sample came from Chris Eglington in Norfolk.
Winter wheat
Mr Lamyman’s winning wheat crop was grown on his 600ha farm at Worlaby on the Lincolnshire Wolds, just north of Horncastle, on his free-draining, chalky loam soils.
This was closely followed by neighbour Mark Stubbs with a yield of 16.70t/ha, while third place came from a grower in Denmark.
The new feed wheat variety Champion was chosen by Mr Lamyman, and after previous work using the nitrogen-phosphate-potash foliar feed TipTip on his oilseed rape.
This was used on wheat at the T3 ear wash stage, and he was “blown away” with a very high specific weight of 83.6kg/hl from a variety that can tend to give medium to low values.
Mr Lamyman uses high doses of nitrogen in a range of 310-350kg/ha for his record crops, but due to a dry autumn, and therefore a good level of mineralised nitrogen in the soil, his winning wheat crop received only 314kg/ha.
His total variable costs for seed, fertiliser and sprays was a not-too-excessive £850/ha.
Even using relatively high nitrogen levels, he is getting good nitrogen use efficiency and so argues that this is a more environmentally friendly approach by being efficient and getting such high yields rather than only achieving moderate yields.
His success came when the UK 2022 harvest saw overall wheat yields rise 10% to 8.6t/ha to produce a national crop of 15.54m tonnes – one of the highest on record – and marking a strong recovery from the low point of just below 10m tonnes at harvest 2020.
Best potential wheat yield in the YEN came from Ashley Jones, operating the mixed 190ha Smeaton Farm, near Saltash in eastern Cornwall, where he is a AHDB Monitor Farmer and is a previous YEN winner.
Winter barley
Mr Lamyman was advised to bring the drilling of his winter barley variety Tardis forward three weeks by agronomy expert David Robinson from advisory group Frontier as the crop followed barley rather than wheat, so there was no threat of wheat volunteers.
The drilling date was 26 September rather than 14 October, and then the same foliar treatment was used on the barley ears as with the wheat.
The result was a massive 16.21t/ha crop – again more than double the national average – and a “wheat type” specific weight of 73.2kg/hl.
The success came in a good year for winter barley with UK national yields up 9% at 7.4t/ha, and with a higher area this saw total production up 17% at 3.2m tonnes
At harvest 2021, Mr Lamyman broke the world record with the same variety yielding 14.2t/ha, topping the old record of 13.8t/ha set by New Zealander Warren Darling.
The silver award went to mixed farmer and AHDB Cereals and Oilseeds sector council member David Bell from East Fife in Scotland.
He produced a 13.40t/ha harvested crop, which also won him the gold award for the best potential winter barley yield.
Spring barley
Mr Budden won gold for spring barley on his 460ha Netherly Farm, Chalton, just above Portsmouth on the Hampshire Downs.
Early drilling got the variety Laureate off to a good start before the drought kicked in and the crop yielded 11.02t/ha.
The crop was drilling on 28 January, while nitrogen levels were trimmed back to 150kg/ha after the previous year’s 175kg/ha had produced a lush crop that suffered in heavy summer rains.
This nitrogen was applied in two doses when the crop had just emerged.
The crop gained from rain in February and March before the dry weather began, and the high yield diluted the nitrogen content of the malting quality grain down to an amazingly low 1.2%.
“It was so dry we had no need for any plant growth regulators and the crop stayed green with little disease,” said Mr Budden, who won the YEN gold award for milling quality wheat in 2021.
The result reflected higher yields nationally for spring barley, with UK average yields up 9% at 6.2t/ha, although a contraction in the area saw production down 1% at 4.2m tonnes.
The silver award went to Dyson Farming of Lincolnshire with a yield of 10.6t/ha. The business, owned by Britain’s biggest farmer Sir James Dyson, also won gold for the highest potential spring barley yield.
Oilseed rape
Tim Lamyman scooped up gold for his gross output yield of 8.98t/ha for oilseed rape, which would have been a world record but it was only grown across 2ha and world record attempts need to be across at least 8ha.
The current rapeseed record is held by Kent grower Richard Budd with a 7.19t/ha crop harvested in 2019.
Mr Lamyman used a mix of the conventional variety Acacia and hybrid Attica at a reasonably heavy drilling rate of 70 seeds/sq m.
The Attica grew more than 2m in height and the Acacia filled in below to give more than 1m height of pod canopy to harvest.
The mixed-variety approach is used by Mr Lamyman to deter cabbage stem flea beetles, with Attica emerging first and then Acacia, which tends to attract any flea beetles while the Attica grows away.
In the UK, oilseed rape yields at harvest 2022 rose sharply, showing an increase of 16% to 3.7t/ha, and with the first rise in area for a number of years, the national crop rose 39% to 1.36m tonnes.
The silver YEN award went to Lincolnshire neighbour Mr Stubbs with 7.82t/ha, while the best potential yield came from David Passmore on the southern edge of the Chiltern Hills in Oxfordshire.
