LG Skyscraper Performs in a Range of Situations
From early to late drilling, ploughed land to min-tilled, and high to low soil fertility, Fife farmer and contractor Zander Hughes faces almost every possible cropping scenario across the 320 ha (800 acres) he farms for a range of clients.

Such variability represents a stern test for any variety, but for Mr Hughes, LG Skyscraper continues to be the stand-out performer in terms of its consistent yield and quality across multiple seasons, and flexibility to go into a range of drilling situations.

Having grown LG Skyscraper since its launch five years ago, the variety once again accounts for his entire winter wheat area, with around 130 ha in the ground for harvest 2024, up from 81 ha last season, due to rotational shifts and a slight reduction in spring barley area. Most is sown as a first wheat after potatoes, vegetables, grass, or spring barley.

“We’ve never had any problems with LG Skyscraper; we really like it as a variety. To this day, LG Skyscraper remains the variety that produced the biggest yield I’ve ever grown, at 14.5 t/ha in the year we first tried it.”

Although last year’s crop did not quite reach that level, he says it still performed really well, averaging 10.5-10.75 t/ha across the whole wheat area, with big, bold grains, good quality, and plenty of straw that stood well.

That performance came despite relatively high disease pressure last season, and challenging conditions that meant the first T0 fungicide, plus growth regulator, could not be applied, he notes.

“That did put slightly more pressure on the T1 and T2 growth regulators in high fertility situations, but despite this, crops generally still stood really well.”

Looking good in a tough year

As for this year’s crop, Mr Hughes says the vast majority was drilled into good conditions, despite tricky autumn weather that stretched the drilling window from 1 September to mid-November. Some fields were ploughed, while others were min-tilled, although decisions are very much taken on a field-by-field basis, depending on soil conditions and previous cropping, he notes.

LG Skyscraper has a fairly vigorous growth habit once it germinates, so Mr Hughes has no fear of sowing it later, as he might with some other varieties.

As always, seed rates were adjusted according to drilling date and conditions, ranging from 375 seeds/m2 at the lowest, up to 525 seeds/m2 in the most challenging situations last autumn.

“At the moment, there aren’t really any obvious differences between the early and late-sown crops. We’ve found that standing water on some fields – which is a new thing for us this year – has had more of an effect than drilling date.”

With most crops around growth stage 31 (T1) at the time of writing, Mr Hughes says generally the LG Skyscraper all looks well, with no obvious issues, despite ideal conditions for Septoria and yellow rust development over much of the season so far.

Given higher disease risk, robust SDHI and triazole-based T1 and T2 fungicides will be used to protect the important yield-building leaves through the remainder of the growing season, and maximise crop potential. This will build on the prothioconazole-based T0 applied earlier this spring, accompanied by trinexapac-ethyl and chlormequat growth regulators, and trace elements.

“Growth stages are slightly all over the place at the moment, even within the same field, so we’re hoping the T0 growth regulator will reduce the apical dominance of the main stems a bit, as they’re a lot further on than the tillers at this stage. We’ll also apply another growth regulator at T1, although decisions are taken on a field-by-field basis.”

Nitrogen is usually applied in three doses, but this year Mr Hughes has favoured more of a “little and often” approach, based on four applications of granular fertiliser, roughly in a 30-40-20-10% split, to reduce any potential risks of field losses due to the weather. Total application generally averages around 210 kg/ha, although this ranges from 180 kg/ha to 240 kg/ha depending on soil levels and crop potential.

 

Sticking with LG Skyscraper

Looking ahead to next season, Mr Hughes plans to continue growing LG Skyscraper, although is also going to try Limagrain UK’s new hard Group 4 variety, LG Beowulf, which joined the AHDB Recommended List this year as the highest yielding winter wheat.

LG Skyscraper is just one of 16 varieties featuring in a Limagrain UK variety demonstration that Mr Hughes is hosting for the first time this season.

“The demonstration is being held on one of our contract farms that hasn’t grown wheat for around 15 years. My initial plan was to go with LG Skyscraper on this farm, because it’s one we like and has done well for us, but there was some debate as to what variety would best suit the farm, hence hosting the trial here.”

As well as a range of Limagrain UK and competitor varieties, the demonstration is also looking at the impact of different seed rates on four Limagrain wheats, sown at half, three-quarters, 100%, and 125% of the standard seed rate.

Crusoe tops YEN wheat quality awards

Limagrain UK’s benchmark milling wheat variety, Crusoe, has claimed the top three positions in the Yield Enhancement Network (YEN) Milling Wheat Quality awards.

Richard Budd

It is welcome recognition for the Group 1 variety that, in the 12 years since joining the AHDB Recommended List, has established itself as a firm favourite amongst growers and millers due to its consistent yield and quality performance, across a range of very different seasons.

First-place in the 2023 YEN award went to Richard Budd, of Stevens Farm (Hawkhurst Ltd), who grows around 220 ha of Crusoe across 1,400 ha in Kent and Sussex. The farm’s focus is on growing quality Group 1 and 2 wheats, to supply local flour mills and occasional export markets, and he values the reliability that Crusoe offers.

“We’ve only been growing Crusoe for three or four years, as previously we had been doing really well with KWS Zyatt and Skyfall. But, they both became uneconomic to grow due to their disease profiles, so last year we made the decision to go completely with Crusoe, which now accounts for one-third of our wheat area, alongside KWS Extase and Mayflower for the remainder.

“So far, Crusoe has served us well. It’s yielded well, is relatively clean and easy to manage, stands well and has a good specific weight, protein, and Hagberg. It’s a solid, stable variety.”

With milling wheat premiums touching £72/t over feed at the time of writing, and predicted to stay firm for the foreseeable future given tight European supplies, Mr Budd is cautiously optimistic for the 2024 harvest, despite a challenging start to the season.

“Admittedly, I’d like an extra 5% yield, but I understand UK flour millers may be less keen on that due to the potential protein dilution. We do need some new genetics in the Group 1 sector, but at the moment, Crusoe is our default variety.”

Hitting protein spec

Chris Eglington

Norfolk Crusoe grower, Chris Eglington, won gold in the 2022 YEN Milling Wheat Quality awards, and claimed silver with the variety in 2023, recording the highest grain protein of 13.7% and one of the highest specific weights at 78.2 kg/hl for his 10.5 t/ha crop.

He too values Crusoe’s performance in what was a tricky 2023 season.

“Yes, it’s been around a while now, but it’s great to have a variety that we know how to manage and know will perform well.”

Last year’s crop followed oilseed rape, with land cultivated using an 8-metre Väderstad Carrier prior to drilling on 14 September, then rolled and a residual herbicide applied.

Variable rate potash, lime (where required) and nitrogen applications are used across the farm, and he has worked closely with grain buyer Camgrain, and in the past with Sainsbury’s, to optimise nitrogen inputs and protein.

Mr Eglington recognises nitrogen management could be more challenging this spring, given the impact of the exceptionally wet autumn and winter on residual soil levels.

“We’re already towards the top of what we can apply in terms of nitrogen, so I don’t think our programme will change drastically. We’ve always found the highest yields come in years when we’ve managed to get nitrogen on early, and fortunately we did manage to apply the first lot of nitrogen during a narrow window in early February, and might apply some more in early March, depending on how the crop looks.”

Typically, first wheats receive a total of 280 kg N/ha, applied as four splits of solid granular fertiliser, sometimes supplemented with a small amount of liquid urea towards the end of the season (June), to help build grain protein if required.

Regular tissue testing is also used to adjust the nitrogen programme according to crop need.

Mr Budd also recognises the importance of early nitrogen to support tillering and biomass accumulation, and has previously seen good results from applying two large splits of 80-90 kg N/ha when conditions allow in February, and again in late March/ early April. Tissue testing is then used to refine later applications according to crop requirements.

Staying disease free

Mr Budd’s nutrition strategy is supported with a robust, preventative fungicide programme, tailored to disease pressure around each spray timing and varietal resistance. His aim is to keep upper and lower leaves free from disease as long as possible, rather than relying solely on the flag and leaf two to build yield.

“With our direct/ strip-till system, we find that if we can keep leaves 3, 4, and even 5 and 6 relatively clean throughout the year, they are still contributing quite a lot to final yield, right up to cheesy ripe stage.

“That said, we’re not applying maximum rate fungicides all of the time; decisions are guided by what’s there at the time, and varietal choice.

“I like Crusoe; it is a relatively easy, clean variety, with good Septoria scores, and yellow rust is non-existent really.”

Late-season brown rust is something to watch out for in some years, but even that is relatively easy to control, with a good range of chemistry available, he notes. “As an industry, we need to be looking more at genetics rather than a can.”

Edward Vipond

Confidence to invest

Having confidence in a variety’s ability to regularly achieve milling specification is vital for Suffolk farmer Edward Vipond, who says Crusoe has become the “go-to” variety in the first wheat slot at the 1,400 ha Troston Farms, near Bury St Edmunds.

The farm grew 160 ha of Crusoe last season, and has increased this to 224 ha for 2024.

“When you’re spending a lot of money on fertiliser to obtain a milling premium, applying 270-280 kg N/ha for example…

“…you need confidence that the crop will deliver in terms of protein, and Crusoe does that. Protein is as much down to the variety’s genetics as how you manage it.”

He also notes that Crusoe seems more consistent than other milling wheats grown on the farm. “For us, even at yields of 10.5 t/ha, it will still regularly obtain 13.3-13.5% protein.”

Last season’s wet summer did pose challenges for protecting quality, with milling wheats prioritised for harvesting slightly earlier than they might have been in a drier year, Mr Vipond says.

This did raise a few issues with thrashing on the combine, resulting in some unthrashed tips in the grain sample, but he insists the benefits of hitting milling specification far outweighed any drawbacks.

“There aren’t that many other competitors in the Group 1 list at the moment. There are one or two coming in, but they’re yet to be proven and have got to do something special to knock Crusoe off. Crusoe suits our land and it delivers.”

Mr Vipond says flexibility and attention to detail are key to getting the best from any crop, particularly in terms of drilling date, seed rates, nutrition and other inputs. He generally drills Crusoe in early October to reduce BYDV risk, opting for seed rates of around 325-350 seeds/m2.

There is no fixed cultivation or drilling strategy though, instead the farm opts for whichever equipment suits conditions at the time. Some fields after potatoes or onions, for example, are established with a plough and combination drill, while others may receive a non-inversion deep tine (e.g. Sumo Quatro) before drilling with a disc or tine machine. “Every season is different, so we do what is required.

“Yield is still king, and if you can get decent yields of good spec milling wheat at a premium of £50-60/t, the return is still there. With the results we had from Crusoe last year, what’s not to like?”

Introducing Kurtis Scarboro – Arable Development Officer

Kurtis started his career in the agricultural industry over 10 years ago, working on a mixed livestock and arable farm, before moving into a role within crop trials at NIAB.

In 2022, Kurtis completed a BASIS certificate in crop protection, giving him an additional recognised industry qualification.

Kurtis says, “I am excited to have joined Limagrain UK, and look forward to the variety and the challenges that the job will entail. I have always been interested in furthering my knowledge within the industry. My new role will help me achieve this, especially working within such an experienced and knowledgeable technical team.”

Since starting in September 23, Kurtis has spent a lot of time working with individual crop teams and getting to grips with the Limagrain variety portfolio (there is still a long way to go!).

Kurtis has been helping to plan and organise the drilling of winter wheat demo sites across the UK, at Rothwell, Woolpit, Newbury and Perth. In addition, alongside Ron Granger, he has also implemented a range of agronomy interaction trials at Rothwell, across wheat and barley. The wheat variety demo compares 36 different varieties, including some new promising Limagrain lines, with treated and untreated replicates. Despite the weather, the Rothwell Demo site was drilled over the first 2 weeks of October, using a Wintersteiger trials disc drill with help and thanks to the Rothwell breeding teams.

Summing up his time at Limagrain so far, Kurtis comments, “I look forward to collaborating with people both internally and externally within the industry, and seeing many of you at the LG open days next summer.”

The benefits of oilseeds in your rotation
With the most recent AHDB early bird survey estimating that the UK winter oilseed rape area has declined by 16% for harvest 2024, partially due to the challenges around establishment, it is easy to overlook the benefits that OSR can bring into an arable rotation.

 

Whilst of course it is important that crops are economically viable, the bigger picture in terms of what added value OSR has to growers, should not be taken for granted. So, whilst growers may begin to question the place of OSR in the rotation, it is worth considering the following benefits below:

LG Skyscraper delivers gold for Lincs grower

It’s second time lucky for Lincolnshire grower Mark Stubbs as he takes top prize in the ADAS Yield Enhancement Network Cereals competition for 2023, with his crop of LG Skyscraper winter wheat yielding an outstanding 16.6t/ha. His last win was in 2019, with a crop of KWS Siskin that yielded 16.3t/ha.

Mr Stubbs puts his success down to an attention to detail encompassing delayed drilling, widespread use of farmyard manure and a move away from ploughing.

Farming 688 ha’s across two sites, on the Wolds and along the coast, wheat is the mainstay of the rotation which also includes oilseed rape and spring barley, for A&C Stubbs & Sons.

The block of 120 ha’s on the Wolds at Marsh Chapel is a heavy, clay site and Mr Stubbs has been growing LG Skyscraper here for several years.

He has always been pleased with the variety’s yields, which have averaged 10.5t/ha over this time. Grain quality has also been consistently good, and while this is not crucial to him from an end market point of view, specific weight is a priority with last year’s crop delivering a very acceptable spec weight of 80kg/hl.

LG Skyscraper joined the AHDB Recommended List in 2019, as the highest yielding wheat and maintained this pole position in 2020. Since then, it has remained a firm favourite on farm for its consistent high yielding performance across seasons, strong agronomics and suitability for later drilling for black-grass control.

Mr Stubbs’ attention to detail and planning before the season begins is a key part of his approach.

This starts with variety choice; he grows seed crops of new varieties, so is in a good position to see what varieties do well in the colder, exposed Wold conditions, or in fields along the coast.

The 2023 YEN winning wheat crop followed an oilseed rape crop that was allowed to green-up for as long as possible acting as a catch crop, before cultivating with a tine disc cultivator and packer, followed by a shallow disc cultivator.

Wheats are generally drilled around the last week of October; however, last year it was very wet, so he waited a week, drilling the LG Skyscraper on 11 November, at a rate of 250kg/ha aiming for a plant population of 275 plants/m2 in the spring.

His aim – given the blackgrass legacy – is to produce a thick, competitive crop which has immediate access to nutrients, so that it can grow away strongly.

LG Skyscraper has a fairly vigorous growth habit once it germinates, so I don’t worry about sowing it later, as I might with some other varieties,” he says.

After several years of growing wheats, and particularly LG Skyscraper, Mr Stubbs recognises the importance of optimising crop nutrition to achieve the high yields he is pushing for.

He says manures, which are applied to stubbles and then incorporated within six hours, have seen the soil organic matter rise from an index of 2-10 despite the highly, acidic calciferous soils.

“We find that the nutrition contained in the manures kicks in early on, giving the crop a good start.”

For the YEN crop, liquid Nitrogen (225N,10%S) was applied in three splits, four weeks apart, and on average received 210kgN/ha, excluding the manure.

He favours a “little and often” approach, and in-season crop monitoring to fine-tune requirements. “We soil test and use the Yara N-tester to gauge how well the plant is doing and to address any shortfalls.”

A standard four spray programme was used for the LG Skyscraper. “ The variety has a weaker rating for Septoria (4.9), so it is important to tackle this early which means we are not chasing disease through this season, and in doing so we have never had too much of a problem,” he says.

“I don’t cut corners in terms of timing but will alter products according to the weather and disease pressure at the time.”

“Despite being slightly taller-strawed, lodging in LG Skyscraper has never been an issue even on the more fertile Wold soils, but we use PGR’s as and when needed, to support the crop we have in the ground.”

“As last year’s crop was grown on the March site with heavier soils, crop emergence and growth were slower, and coupled with late drilling, the crop didn’t reach a leggy stage, so a robust T1 was used which proved sufficient to regulate the crop.”

He explains that a T0 was applied but with the key aim of manipulating the plant to ensure it was strong and healthy, and a bio stimulant was applied to boost the plant’s defence mechanism to fight any initial infections.

Harvest took place on August 10 – which Mr Stubbs points out was early for a late-drilled crop. “It literally turned overnight, it wasn’t ripe when we checked it two days before, so I think we caught it just in time.”

His YEN report is useful and highlights where attention to detail is needed.

“We’re using YEN where we can to improve the farm,” Mr Stubbs says.

Limagrain Upgrades Malting Barley Laboratory at UK Head Quarters

Our malting barley laboratory at Rothwell in Lincolnshire has been upgraded to increase testing capability for the early screening of new varieties, from 1000 to 4000 samples a year, for both the UK and European markets.

“This will allow us to use the data generated more efficiently to enable more accurate genomic selection, to better predict the malting potential and quality of the next generation of malting barleys,” says Sophie Buon, barley breeder.

“This new approach will test varieties under different micro-malting regimes, that require less water and less steeping – and in response to end user requirements, do this in the most carbon neutral way possible.”

“We hope that the new facility will encourage end-users to visit and see for themselves, the extensive work that we are doing to breed new and exciting malting barley varieties, that meet all of today and tomorrows market requirements.”

Limagrain varieties top the 2024/25 AHDB Recommended List
Plant breeder Limagrain’s winter wheat LG Beowulf and 2-row winter barley LG Caravelle, are the highest yielding varieties to join the 2024/25 AHDB Recommended List.

LG Armada also takes lead position as the highest yielding oilseed rape variety on the Recommended List for the UK, whilst LG Adeline takes pole position for oilseed rape in the North.

In addition, high yielding maize variety Saxon tops the 2024 BSPB Forage Maize Descriptive List for ME yield (‘000s MJ/ha).

This means that LG now offer the highest yielding varieties in; winter wheat, 2 row winter barley, OSR and maize*.

Ron Granger

“This is an exceptional achievement for any breeder,” explains Ron Granger, Limagrain’s arable technical manager.

“Last year saw our winter wheat and winter barley varieties take pole positions across the RL. We have built on this success for a second year running, producing higher yielding varieties, backed up with desirable agronomic characteristics, securing high yield performance on farm. What’s more, these varieties have proven to be robust and consistent performers across seasons and regions.”

 
Highest yielding winter wheat

Group 4 hard wheat LG Beowulf yields 106% across the UK and shows the same consistency of performance across all regions: east (106%), west (106%) and the north (107%) – an outstanding achievement for any variety.

LG Beowulf has produced these exceptionally high yields consistently in National List and RL trials over regions and seasons, in both the unusually dry summer of 2022 as well as the exceptionally wet summer of 2023. Alongside these yields, it offers a good grain quality, with a spec weight of 78.3 kg/hl.

LG Beowulf is much like LG Skyscraper; it performs wherever you grow it,” he says. “It can be drilled early or late – providing growers with a wide drilling window, as a first or second wheat, on light or heavy land, and there are very few varieties that meet this criterion,” he says.

LG Beowulf yields are backed up by a set of strong agronomic characteristics, offering an excellent disease resistance profile with ratings of 9 for yellow rust, 6.7 for septoria, as well as orange wheat blossom midge (OWBM) resistance.

It has very stiff straw and is rated 8 for standing in untreated and PGR treated trials, which strongly contributes to its reliability on farm.

“In summary, LG Beowulf is a very high yielding, robust and versatile variety that comes at a time when growers are looking more than ever to maximise output, in order to maintain profit in times of increasing costs,” says Mr Granger.

 
Highest yielding winter barley

LG Caravelle is the highest yielding two-row winter barley for the second year running, since joining the Recommended List in 2023.

“Offering UK yields of 105.6%, LG Caravelle continues to dispel any misconception that two row barleys are lower yielding than hybrids. The variety certainly competes with the best yielding hybrid barleys, especially in the east,” says Mr Granger. “LG Caravelle is competitive in a black-grass situation, another characteristic that is normally associated with hybrids.”

LG Caravelle’s high yields are backed up by an excellent disease profile, reflected in its superb untreated performance, it is early maturing with stiff straw and good brackling resistance.”

LG Caravelle also offers an exceptionally high specific weight for a winter barley, of 71.4 kg/hl combined with low screenings %,” he adds.

“Indeed, LG Caravelle possesses all of the key characteristics for a winter barley.”

LG Capitol is a two-row winter barley that joins the Recommended List this year and is a sister variety to LG Caravelle, offering similar yields and consistency of performance over seasons and regions. Its yields sit just 0.1% behind that of LG Caravelle, at 105.5%.

LG Capitol also combines a high specific weight and ripening, similar to KWS Tardis, with a solid disease resistance profile and good straw attributes.

 
Highest yielding OSR

The top three highest yielding oilseed rape varieties on the 2024/25 AHDB Recommended List all come from the Limagrain stable, offering exceptional consistency over regions and seasons.

LG Armada tops the UK and E/W List at 107%, LG Academic follows 1% behind at 106%, with LG Adeline taking pole position on the Northern List with an outstanding yield of 108.3%.

LG Armada is one of the next generation of versatile high yielding oilseed rape varieties, improving on the characteristic trait loaded-hybrids that growers have come to expect from Limagrain.

“‘Ambassador-like’ in its growth habit, LG Armada has strong autumn vigour, is robust, with good adaptability to all regions of the UK,” says Limagrain’s oilseeds product manager, Liam Wilkinson.

Liam Wilkinson - Limagrain UK in Oilseed Rape trial plots“LG Armada is the first of our seventh generation of hybrids, bringing new maintainer and restorer lines to our OSR portfolio. This effectively means we are bringing varieties to market offering a stacked portfolio of much improved stem health attributes, alongside the standard pod shatter, TuYV and RLM7 resistance traits.”

“We know stem health is key to driving consistent oilseed rape yields across farms and with these seventh-generation hybrids, we are seeing bigger stems and better rooting which also results in higher oil content,” he says.

 
Highest yielding maize

Limagrain’s maize variety, Saxon was added to the BSPB 2023 Forage Maize Descriptive List and has made the top of the list for 2024 for its ME yield of 225 (‘000s MJ/ha). It has dry matter yields of 19.1 t/ha, making it ideal for all uses, including anaerobic digestion.

“On the Descriptive List, Saxon yields 105% of the average and additionally is quite an early variety with an FAO of 180,” says Tim Richmond, Limagrain’s product manager for maize.

Saxon combines superb early vigour with good standing power, making it perfectly suited for all mainstream maize sites.”

“LGAN has long been the watchword for maize varieties that deliver what really counts – high yields of high-quality feeds that sustain excellent milk yields. Saxon is one of the latest examples of the benefit of breeding varieties that deliver in the clamp.”

Five priorities when choosing a spring barley variety

Five priorities when choosing a spring barley variety

Spring barley is an important rotational option on many farms, and more growers may be looking to the crop in 2024 as exceptionally wet autumn weather has disrupted winter cropping plans.

But, whether the decision to grow spring barley is planned or unplanned, There are some key factors to consider says Limagrain UK arable technical manager, Ron Granger.

Market requirements

Start by fully understanding your grain buyer’s requirements in terms of variety and grain quality, especially when looking to supply premium brewing or distilling markets.

In some instances, contract specifications will dictate the variety that must be grown to supply a particular market, and criteria such as grain nitrogen content, will have an important impact on agronomic decisions and crop inputs throughout the season.

Dual use potential

Where variety choice is not dictated by the end user, growers have flexibility to select one that suits their requirements, growing conditions and farm situation.

Mr Granger recommends considering a dual use variety such as LG Diablo, which combines decent yield performance, with multiple end market opportunities, offering an advantage over many varieties now listed.

Vigour and tillering capacity

LG Diablo offers excellent spring vigour and high tillering capacity, which is a valuable trait in spring barley given the relatively short growing period.

The best way to maximise spring barley yield potential is to ensure high final ear counts. An 8-9 t/ha crop needs around 800 ears/m2, which at a 350 seeds/m2 rate, equates to around 2.5-3 tillers per plant at harvest.

Choosing a more vigorous tillering variety will help, as it will give some reassurance that the optimum tiller count will be reached.

Where spring barley is being used in a black-grass situation, it is important that a vigorous, high tillering variety is selected, as a high tiller number must be ensured for the variety to compete.

Spring barley is a fast-growing crop and if key nutrients are deficient at any time, yield potential will be affected.

Limagrain trials show that higher yielding varieties respond positively to higher nitrogen inputs, due to their increased yield potential and,more importantly, a dilution of grain nitrogen content.

Phosphate, potash, magnesium and sulphur, have proven beneficial to tiller retention and final yield, while micronutrients, including manganese, zinc, copper, iron, and boron, applied at the stem extension phase into flowering, are also useful.

Disease resistance

Strong disease resistance is an important characteristic to look for in any variety, and spring barley is no exception, with mildew, rhynchosporium, and brown rust being the main considerations, says Mr Granger.

Early drilling can significantly increase disease risk, so it may be particularly important to consider more disease resistant varieties for this situation.

Resistance to lodging/brackling

Choosing a variety with good straw characteristics, is key to protecting yield and grain quality at harvest and potentially offers another significant output from the crop.

While a variety’s RL ratings for lodging and brackling provide a useful indication, it is also important to recognise the role that agronomic decisions play, notably around seed rate, nutrition, and the use/timing of growth regulators.

 

County Durham estate finds perfect variety fit for regen system

A large estate in the North east of England, has turned to wheat variety LG Typhoon as part of its drive to build a more sustainable regenerative cropping system.

The in-house farming operation of County Durham-based Raby Estates began conversion to direct drilling in 2018 and is striving to reduce the use of artificial inputs where possible, without compromising on the quality and quantity of crops produced.

Philip Vickers

It is a challenge that the variety lived up to last season, according to farm manager Philip Vickers, who decided to trial the variety on the recommendation of Limagrain UK’s arable technical manager, Ron Granger.

“We’re trying to move away from growing high input varieties, so are primarily looking for those that offer a robust disease package, good standing power and suitability for our direct drilling system,” Mr Vickers says.

“Direct drilling in northern England is not something you want to be doing into November, so I also look for varieties that suit the early drilling slot. From what we’ve seen so far, LG Typhoon seems to fit our requirements well.”


Strong performance

Last season the farm grew around 32 ha (80 acres) of LG Typhoon, alongside several other varieties, but Mr Vickers has been so impressed with its agronomics, ease of management and yield performance, that he plans to increase this to 100 ha for 2023/24.

The LG Typhoon averaged an excellent 9.4-9.6 t/ha. A number of weather-related challenges throughout the season however, including exceptionally high Septoria pressure, did not make for an easy growing season.

The LG Typhoon was direct drilled in mid-September as a first wheat after oilseed rape, using the farm’s 6-metre Horsch Avatar, or 6-metre Väderstad Seed Hawk, drills. Seed rates were kept relatively high at around 300/m2, to counter the slightly lower establishment percentage experienced when direct drilling.

All crops received a base application of phosphate and potash fertiliser, plus a total of up to 170 kg N/ha in the spring, applied as three splits; the first as granular urea, followed by two liquid nitrogen applications.

“We have been reducing nitrogen use significantly in recent years, but in contrast to conventional thinking, some crop yields have gone up in that period,” Mr Vickers notes.

“Agronomy-wise, LG Typhoon was problem-free,” he continues. “It established quickly in the autumn, got away well in the spring, and was relatively early to harvest, tight behind Graham.”

But even though it established quickly, he says LG Typhoon did not get too large, unlike some other varieties, which continued tillering throughout a very mild autumn, during which temperatures hit 21°C in November. Those varieties then became much harder to manage with growth regulators and fungicides in the spring.


Robust disease profile

Strong Septoria resistance is a must-have for all winter wheat varieties grown on the farm, as the disease remains the number one yield-robber in high pressure seasons such as 2023, Mr Vickers says. “We generally look for varieties with a Recommended List score of at least six.”

With a Septoria rating of 7.3, backed up by a combination of genetics that are different to those in other RL varieties, giving LG Typhoon a distinct advantage over other varieties.

Although crops received the farm standard fungicide programme, based around Iodus (laminarin) at T0, bixafen/prothioconazole at T1, Univoq (fenpicoxamid + prothioconazole) at T2, and straight tebuconazole at T3, he was able to reduce rates by 10-15% on the LG Typhoon due to its robust disease profile.

“To ease management, we generally try to keep fungicide products similar across all varieties, but will look to vary the rate where appropriate.

“Despite doing so on the LG Typhoon, we still didn’t see any disease of significance at all last season, even though there was very high Septoria pressure which caused some other varieties to struggle.”

Accurate spray timing is also key to maintaining effective disease control, as is a robust trace element programme to bolster plant health and reduce the crop’s susceptibility to disease infection, he adds.


Perfect fit for regen systems

Mr Granger says LG Typhoon has certain attributes that make it ideally suited to strip tillage/direct drilling, regenerative crop establishment systems, that often feature wider rows.

LG Typhoon’s growth habit, for example, means plants sit prostrate with slower growth through the winter into spring, which is ideal for those direct drilling earlier in the autumn and who do not want a variety that races off too quickly.

It is a high tillering variety that has the capacity to utilise the space between the wider rows, often found with some direct drilling equipment.

Indeed, while Mr Vickers’s Horsch drill works on a standard row spacing, the Väderstad is at a slightly wider 180-200 mm spacing, and he also trialed a new 12-metre tine drill last season, which worked on a wider 250 mm row width.

“Unfortunately, we don’t yet have the yield data available, as the demo field was combined by a contractor, but the LG Typhoon did seem to really suit that wider row spacing. It’s something we may potentially look at in the future, although I’m not sure a 12-metre machine is suited to some of the smaller fields on our farm.”

Another attribute of LG Typhoon that makes it a good fit for regenerative systems, and for those looking for flexibility with crop protection inputs, is its strong standing power and disease resistance – reflected by its high untreated yield (92%), Mr Granger says.

Unlike some other feed varieties, it also offers Orange Wheat Blossom Midge (OWBM) resistance, in addition to a six-rating for eyespot and Fusarium.

“It’s a high yielding, consistent and resilient variety, that delivers across seasons and rotations.”

LG Caravelle proves its value

Two row winter barley, LG Caravelle, joined the AHDB RL last year as a contender to match hybrid barley yields, and early harvest reports confirm that it has lived up to its promise.

Despite the challenging season, the variety has performed well on the Yorkshire Wolds. Mark Ullyott of Langtoft Grange Farm near Driffield, is really pleased with his seed crops of LG Caravelle, yielding between 8.5-9.5 t/ha.

“We have grown seed crops of barley for over 10 years, and LG Caravelle must be the best we have seen,” he says.

He grew two fields this year: one following vining peas and the other after potatoes. The crop following the vining peas was drilled on the 28th September at the standard seed rate of 300 seeds/m2. This field was ploughed, pressed & combination drilled.

The field following the potatoes was min-tilled and went in a bit later, on the 23rd October, with a slightly higher seed rate of 350 seeds/m2, to compensate for the later drilling.

Both fields established well and looked pretty good. “We don’t have too much of a black-grass issue, so a pre-emergence application of flufenacet and diflufenican at 0.4 l/ha and some Avadex, pretty much tidied up any weeds,” explains Mark.

Disease-wise, the crop stayed clean with a standard fungicide programme, and received 160 kg of Liquid N32/ ha, which was reduced slightly due to the increased fertiliser costs at the time.

“It’s a fairly tall variety, so we used a ‘bottom-shortening’ PGR, chlormequat, but I think the crop would benefit from a ‘top shortener’ as well next time, just to reduce its height that bit more, although it’s important to note the straw strength was good and we didn’t have any lodging or brackling issues.”

“Both fields were ready to harvest by the third week of July, but the wet weather meant the field following the vining peas was ready first on the 31/7 but we had to hold on for another week for the second field, again due to the weather.”

“Despite this, the crop held its own, germ still looked good and bushel weight held up with no sprouting. The straw came off well; all of which goes for home use,” he adds.

“It is always interesting growing a new variety for the first time to see how it performs, and we are very pleased with LG Caravelle and will grow it again. If we could, we would put all of our acreage down to the variety,” says Mark.


LG Caravelle joined the 2023/24 Recommended List as the highest yielding two row winter barley.

“We launched the variety not just on the back of its high yields but with a confidence that the variety would deliver across a range of conditions,” says Ron Granger, Limagrain’s arable technical manager.

“The years running up to its recommendation were dry and the variety yielded exceptionally well, however this season has been much wetter but LG Caravelle has upheld its promise of consistency and delivered the yields – and that’s a very valuable attribute on farm.”

Ron explains LG Caravelle’s yield potential is backed up by its specific weight. “Specific weight is important no matter what, and LG Caravelle’s is very high at 71.8 kg/hl. It’s one of the best scores available and is only surpassed by KWS Cassia.”

LG Caravelle’s yield potential is also bolstered by its disease resistance profile, says Ron. “The variety has a 7 for mildew, a 6 for rhynchosporium and a 5 for net blotch,” he explains. “Although there’s no rating on the RL yet, our data indicates the variety scores a 7 against brown rust, which is high against this disease.”

The variety also has resistance to barley yellow mosaic virus, giving it all round disease resistance, he adds. “The culmination of this can be seen in its untreated yield.” “It has a very high untreated yield of 89%, which really gives growers security,” he adds.

Ron feels that growers who’ve been growing hybrids might be interested in returning to two-rows because of LG Caravelle’s performance. “Hybrids account for about 20-25% of the winter barley market but this could change. Plus, we’re currently testing to see if LG Caravelle could be suitable for more than just the feed market.”

“We’re seeing the next step in on-farm varietal security for farmers and these types are proving to be an option on-farm again.”
