Introduction

Dennington Hall Farms is a family-run 1,600-ha heavy land farm in east Suffolk, that has recently transitioned to a regenerative farming system as part of its ongoing commitment to sustainability and responsible land stewardship.

There is a particular focus on building the health of the predominantly heavy clay soils, promoting biodiversity, and sequestering carbon, through a range of techniques, including; reduced tillage, cover and catch crops, a diverse 12-year rotation, and managed grazing.

Cropping includes; winter wheat (mainly Group 4s for local feed markets), oats, spring barley, winter barley, sugar beet, vining peas, beans, mustard, oilseed rape, plus Wildfarmed bi-crops, cover and catch crops. Livestock – sheep from a neighbouring farm – are also integrated to graze cover crops.

How many different varieties are grown and how long would you grow a variety for?

This season, the farm is growing around 15 different varieties across all crops, plus several blends. Varieties include:

• Wheat: LG Typhoon, LG Redwald, LG Beowulf, Champion, KWS Extase, KWS Dawsum
• Winter barley: KWS Tardis, LG Caravelle
• Spring barley: LG Aquarius
• OSR: Campus
• Spring oats: WPB Isabel
• Three-way wheat blend trial of LG Redwald, Champion, and KWS Dawsum
• Wildfarmed blend of spring wheat, and Laureate spring barley
• One variety each of beans, mustard and vining peas

Farm manager Ryan McCormack says a variety is usually grown for three or four years (assuming no disasters in year one), before deciding whether to replace it with something else.

“That decision depends how strongly it has performed; there’s no real timescale for how long we’ll keep any variety for. Generally, we’ve got four or five mainstream varieties, and every year we look at what’s new, what’s going to work for us, and then replace the weakest of those main varieties.”

Sometimes a new variety may be trialled on a small 30-40ha area first if there are potential question marks over how it might perform, but he may also commit a whole 100ha block if confident in its potential – as was the case with LG Beowulf and LG Typhoon this season.

What characteristics are most important to you when choosing a variety?

While yield is important, Mr McCormack’s aim is to select varieties that also have good agronomics and characteristics to suit the specific requirements of different parts of the varied rotation.

“After sugar beet, for example, we’re looking for something that gets up and away quickly, and has high vigour, even if sown late into sub-optimal conditions, which is where LG Redwald fits in.

“On other parts of the rotation, we’re looking at lowering our inputs and reducing cultivations, so that’s why LG Typhoon was chosen, as it can be direct drilled, knowing that we’ll get a good plant stand – it has that agronomic advantage over some other varieties.”

Have these characteristics, or weight of importance, changed over recent years?

The farm’s approach to variety selection has evolved with the move to regenerative farming, Mr McCormack says, with greater focus now given to finding the agronomic characteristics that suit specific situations, to improve yield security.

“Traditionally the farm would have been more intensively cultivated, drilled early, looking primarily for high yields, and not necessarily focused on agronomics, gross margin, or soil health when looking at varieties.

“But in recent years, we’ve been focusing much more on gross margin and the other aspects that varieties can bring to the party, not necessarily just looking for ‘barn fillers’. Yield is still important, but it’s about finding varieties that also have good agronomics that suit our soils and the situations we’re putting them in.”

Why have you chosen LG varieties?

This season, Dennington Hall Farms is growing 100ha blocks of three Limagrain varieties, LG Typhoon, LG Beowulf, and LG Redwald.

LG Typhoon was chosen primarily for its suitability to wider-row regen-type systems, says Mr McCormack. “We wanted a variety we could scratch in, or direct drill after legumes, and LG Typhoon seems to be the choice for regenerative farming, given it can go into a very min-till, or direct-drill situation and produce a good plant stand. Agronomically it’s very pleasing and has good yield potential.

“It has definitely got different characteristics to other varieties; it spreads and stays quite flat to the ground over winter, which is good for wider rows, or direct drilling scenarios, where you want a developed canopy to smother any grassweeds before stems start extending.”

He also values LG Typhoon’s suitability for earlier drilling. “We’re not drilling really early, but typically look to start in the first week of October with LG Typhoon, and aim to finish by the end of October.”

LG Redwald, grown for the first time in 2023/24, was chosen for its vigour when being sown later in the autumn after sugar beet. “LG Redwald is known for being very vigorous, and might seem a risky choice for highly fertile, heavy soils, but if it’s being drilled late into a sub-standard seedbed after sugar beet, you want that extra vigour to grow away and still yield well.”

Another new addition this season is LG Beowulf, grown as a first-wheat after oilseed rape. “I saw it twice in trials last year and for me, it was the stand-out variety for its agronomics, yield potential, and vigour,” says Mr McCormack. “I’d describe it as the ‘heavy land LG Redwald’.

“LG Beowulf is clean, high yielding, and has good vigour, but suits our fertile, heavy soils. It’s everything we want from a variety right now.”

LG Redwald also features in a three-way blend alongside Champion and Dawsum, which is being trialled to see if mixing genetics and agronomics can help reduce disease pressure, improve plant stand, and maximise yield.

The farm is heavily into conservation, so avoids using insecticides wherever possible, therefore having Orange Wheat Blossom Midge resistance in all three Limagrain varieties helps in that respect, Mr McCormack notes.

How are the varieties performing to date and have you managed them differently this season?

At the time of writing, approaching the T2 timing in mid-May, Mr McCormack says the 100-ha of LG Beowulf after oilseed rape looks the strongest of the wheats.

“It looked well all winter and early spring, although the lack of rain is a concern for all crops. Coming into spring, it looked like a 12 t/ha crop of wheat, but if I had to put a figure on yield now, I’d say it’d be nearer 11 t/ha, which is still very good. That might reduce to 10 t/ha if we don’t get any rain in the next three weeks though.”

Mr McCormack says a different establishment approach was tried on some fields of LG Beowulf this season, whereby a summer catch crop went in after the OSR harvest, which was mob grazed with a neighbour’s sheep, before direct drilling LG Beowulf on 27/28 October. “That’s later than most people would drill first-wheat after oilseed rape, but it was a good opportunity to bring a catch crop and livestock into the rotation. It also improved soil resilience to a spell of heavy rain in mid-October.”

Given the dry spring, the LG Beowulf has only received liquid fertiliser, while other varieties have had a 50:50 split of granular and liquid fertiliser.

Disease pressure has been relatively low across all varieties, with no real issues seen thus far, other than odd incidences of rust and Septoria, Mr McCormack says. As a result, he has been able to reduce fungicide spending at the T0 and T1 timings, adjusting both product choices and rates to risk and yield potential.

The later-sown LG Redwald has so far received the lowest fungicide input, reflecting the fact that yield potential has been compromised by an estimated 1-1.5 t/ha due to late sowing after beet, and a very dry spring, he says. The more open canopy also means ground has dried out slightly more than in the other LG wheats where larger canopies have provided more of a shading effect, he notes.

While fungicide inputs have been reduced overall, this has been supported with additional micronutrients, such as manganese and magnesium, to build plant health and natural disease resilience.

Mr McCormack says LG Typhoon has stayed true to its characteristics, remaining close to the ground in early spring, before a dramatic change in late April/early May as growth started to extend upwards.

“Now it’s looking good, and more vigorous. If I had to put a yield on it at this stage, I’d say it’s on the ‘good’ spectrum, at around 10 t/ha, providing we get some much-needed rain in the next few weeks.”

The blend trial looks well, although he admits the dry conditions have not really tested the aims of the trial. “We haven’t had the disease pressure, nor have we been increasing fertiliser due to massive yield potential, so it’s hard to judge performance. Crops look well from the field edge, but once you get into them, you often find they haven’t put huge amounts of biomass on.”

Finally, if a breeder gave you three wishes for varietal traits what would they be?

One key trait would be to have mainstream wheat varieties with resistance to barley/cereal yellow dwarf viruses (BYDV), to remove the need for using any insecticides in the autumn, says Mr McCormack.

Ergot is another issue that can be “a bit hit and miss”, so removing that through varietal breeding would be beneficial, he says. Another is gout fly resistance, as that seems to be becoming an increasing issue, he adds.

“Finally, if I were to fast forward 20 years, we’d be looking to grow varieties that allow us to be fully self-sufficient, so we’re not having to buy in lots of fertiliser and we can supply the nutrients required.”

Saskatchewan Pulse Growers (SPG) and Limagrain Field Seeds are excited to announce a new collaboration for pulse breeding in Saskatchewan, Canada.

This new collaboration has a strong commercial focus and will bring new and additional investment into pea and lentil breeding locally in Saskatchewan, increasing competition, and creating a strong
environment to foster innovation.

Developing new and better performing varieties of peas and lentils is the focus of the breeding collaboration. Farmers’ priorities and greatest production challenges are at the forefront of the breeding program, with major areas of focus including resistance to root disease in peas and lentils, increased protein content, and overall improvements in yield performance under varying conditions.

Breeding will take place in Saskatchewan for the benefit of Saskatchewan producers. “We are excited for this new direction in pulse breeding for farmers in Saskatchewan. It is important to continue fostering innovation and competition in pulse breeding and to bring new perspectives to challenging on-farm issues like root rots and herbicide resistance,” says Shaun Dyrland, Chair of SPG Board of Directors.

“We believe this new collaboration with Limagrain on pulse breeding will allow for targeting grower priorities and ensuring that growers’ direction and voices are at the table helping to drive new varieties.”

The new Limagrain Field Seeds breeding, and research program will be based in Saskatoon, where a dedicated pulse breeding team will be created, bringing new expertise in breeding, pathology, molecular genetics, and field trial evaluation to the region.

This technology driven program will lead to higher performing varieties being made available to producers more quickly by deploying all available technology to both shorten the breeding cycle and accelerate seed production.

Commitment and Collaboration

“Limagrain is very committed to producing plant-based proteins. Saskatchewan is at the heart of global pulse production, so it makes perfect sense for Limagrain Field Seeds to extend its existing cereal breeding research in Saskatoon, and to now include these two pulse crops reinforcing our commitment to Saskatchewan,” remarked Régis Fournier, CEO of Limagrain Field Seeds.

“Collaboration is a core value for Limagrain and partnering with SPG, a fellow farmer-led organization is a crucially important component.”

Both SPG and Limagrain are farmer-led with farmer-based boards of Directors. This is an important pillar to this new collaboration, which was developed around shared values to support and foster profitable growth and opportunities for Saskatchewan farmers.

The collaboration has SPG and Limagrain sharing in upfront investments, with future royalties from the sale of new varieties to be shared. SPG will provide input on breeding priorities and ensure that farmers’ voices, needs, priorities, and challenges are driving the goals of the program every step of the way.

Benefits for European and UK pulse markets

Will Pillinger, pulse breeder for Limagrain UK believes European and UK markets can expect to see the benefits from this incredibly significant pulses breeding collaboration in the near future through combined technology and genetic diversity. “The partnership with Saskatchewan Pulse Growers (SPG), has increased our investment in genomic selection and specific trait related genetic markers for peas, beans and lentils.”

“This increased global pulse breeding will have an immediate impact on the ability for Limagrain UK to access accelerated improvements in yield, quality and disease resistance and it should not be too long before we see these attributes on UK farms.”
