Pre-harvest crop analyses, carried out by Limagrain on behalf of local maize growers, indicate that most stands of maize are on track to produce a promising crop, with the majority predicted to be ready for harvest in the next week to 10 days.

The pre-harvest tests (for dry matter, starch, non-digestible fibre, cell wall digestibility and metabolisable energy content) were carried out at a maize demonstration and testing day, hosted by Limagrain and Spunhill at Limagrain’s maize variety trial site on the outskirts of Wrexham.

The event was attended by more than 40 farm businesses from across the region who not only had their own crop samples tested for free, but were also given a tour of the Limagrain variety trial where the latest forage, grain and energy crop varieties are being assessed in an on-farm situation.

“The tests clearly indicated that whilst a minority of crops are already at the point of harvest, the majority are still a week or more away from being ready, with dry matter levels still a little on the low side,” describes Henry Louth, Key Account Manager, Forage Crops, Limagrain UK.

“For most maize growers, the start of this year’s harvest has been delayed by about a fortnight as a result of July’s dull and overcast conditions which saw sunshine hours at 81% of the average for the month. Most crops have caught up well since then, with a few notable ‘very early’ varieties including Dignity and Gema really standing out in terms of maturity. Those two varieties tested particularly well for dry matter, starch and ME content, and also recorded excellent results for cell wall digestibilty.

“If conditions in early October are favourable, we should see most growers taking their crops before the middle of the month, which will hopefully make for a clean and easy harvest and a good quality ensiled crop.”

The event was attended by by more than 40 farm businesses from across the region who had their maize crops tested for dry matter, starch and ME content, and cell wall digestibility.

The tests indicated that the majority of the region’s maize crops  should be ready to be harvested by the middle of October.

Limagrain UK is optimistic that treated maize seed will still be available for the upcoming season as hope grows that the impending ban on seed treatments will be delayed following a successful lobbying campaign.

The future viability of maize being grown in the UK – either for use as livestock forage or as a feed source for AD (anaerobic digestion) plants – has been in question due to an impending ban on all seed treatments including Korit (ziram) bird deterrent, Redigo M (prothioconazole + metalaxyl) fungicide and Force 20 CS (tefluthrin) insecticide.

As it currently stands, from  31^st December 2023 it would be illegal to import, sell or sow any seed which has been treated with any of these products, leaving crops at significant risk of failure.

“Without a suitable bird repellent, insecticide and fungicide, there’s a substantial risk that newly drilled crops could be completely wiped out by corvid grazing, or seriously hindered by insect damage and soil-borne pathogens,” explains Tim Richmond, Maize Manager for Limagrain Field Seeds in the UK and Ireland.

“Corvids are highly intelligent birds, and quickly understand seed drilling patterns, with any attempt to drill seed deeper to prevent bird damage likely to exacerbate the risk of seedling blight, making the application of a fungicide seed treatment such as Redigo M even more critical.”

To counter the ban, which has threatened the industry as a result of the UK’s departure from the EU, an industry working group – spearheaded by Limagrain UK – has been set up to lobby the Government into taking action.

“Limagrain has taken a leading role in this sector-wide campaign which has also included the MGA, AIC and NFU,” Mr Richmond continues. “A number of emergency authorisation (EA) applications have been made to the regulators for the continued use of these treatments for sowing in spring 2024, with a decision on whether the ban will be withdrawn or delayed due imminently.”

The Expert Committee on Pesticides is scheduled to meet in September, with a final announcement are expected to be made before the end of the month.

“As things currently stand, we’re confident that our ongoing discussions with the Farming Minister, the Rt. Hon. Mark Spencer MP, will have a favourable outcome and that all three seed treatments will still be available for use in 2024 – either as a result of the Emergency Authorisations being granted, or because of a change in the law to delay the withdrawal date.”

Despite the imminent announcement there remains significant uncertainty amongst UK maize growers, with some already suggesting they are preparing to sow an alternative crop such as wholecrop winter wheat.

“We appreciate that the clock is ticking and that for some growers any announcement might come too late,” Mr Richmond adds. “But until a concrete decision has been made, we’d urge growers not to rush into making any changes to next year’s rotation.

“We will know more in a relatively short timeframe and will announce the Committee’s decision as soon as it has been made known to us. In the meantime, we are continuing to lobby for the new generation of maize seed treatments to be registered with the CRD as quickly as possible to ensure maize remains a viable crop in the UK in the long-term.”

Limagrain UK will be exhibiting at the UK Dairy Day in Telford on Wednesday 13^th September. Please feel free to visit stand H120 to discuss the latest situation with a member of the LG team.

Three new forage maize varieties from Limagrain have been added to the 2023-24 BSPB/NIAB Descriptive List, with two very early maturing varieties sitting atop the new list of first choice varieties for favourable sites, and the third, a later maturing option, topping the list for very favourable sites.

Skipper and Foxtrot are ranked numbers one and two respectively as first choice varieties for starch yield on favourable sites, while LG31.207 tops the chart for ME yield for varieties suited to very favourable sites.

“With an early FAO of 160, an ME yield of 221,175 MJ/ha and the highest starch yield (6.74 t/ha) on this year’s favourable site list, Skipper is ideal for farmers who want to fill their clamps with a very early maturing crop of exceptionally energy-rich and starch-filled maize,” explains Tim Richmond, Maize Manager for Limagrain in the UK and Ireland.

“Skipper also performs well on marginal sites, where its good early vigour (6.9), excellent standing power (7.6) and early ripening cobs deliver an easy to harvest crop that gives exceptional dry matter and energy yields.”

Foxtrot is also classified as a very early maturing variety (FAO 170) and is second only to Skipper in terms of starch yield (6.54 t/ha). Foxtrot also sits towards the top of the rankings for ME yield (222,363 MJ/ha) and DM yield (18.7 t/ha) and also shows good early vigour (7.2). “And with a Cell Wall Digestibility of 59.4%, Foxtrot is ideal for dairy and beef farmers who are looking for a bulky and very early maturing variety that will improve the feed conversion efficiency of their herd’s ration,” Mr Richmond adds.

The third new Limagrain variety to be added to this year’s Descriptive List is LG31.207: with an FAO of 210, this intermediate to late-maturing variety is one of the best options for very favourable sites.

“LG31.207 is impressive on paper and in the field, and is the perfect choice for those growers looking to maximise their return on investment with a variety that poses minimal risk,” Mr Richmond describes.

“LG31.207 tops the Descriptive List for very favourable sites with an ME yield of 217,115 MJ/ha and dry matter yield of 18.7 t/ha ,” Mr Richmond continues. “And with excellent agronomic traits that include good standing power (8.0) , excellent early vigour (8.2) and an eyespot resistance rating of 7.5, LG31.207 is a really safe choice for growers looking for an energy-rich, easy to grow variety for AD purposes.”

Information: Forage Maize Seed Treatments for Sowing Spring 2024

The Issue

Forage maize seed used in the UK is produced and pre-treated in Europe, with an appropriate fungicide to safeguard it against root zone diseases such as seedling blight, and a bird repellent to discourage corvids from taking the seed.

As part of the European Union free market, seed treated with a crop protection product has free movement across Member State boundaries. Now that the UK is no longer a member of the EU, such rules do not apply and, as of 31 December 2023, it will be illegal to import, sell or sow treated seed with Korit (ziram) bird deterrent, Redigo M (prothioconazole + metalaxyl) fungicide and Force (tefluthrin) insecticide, since the products are not licenced by the UK CRD/HSE.

The Impact

A lack of suitable bird repellent can result in the total loss of the crop. Corvids are intelligent birds and quickly understand seed drilling patterns. In the photograph below, the crows were able to identify which plots were untreated taking almost all of them.

Any attempt to drill the seed deeper to avoid bird damage exacerbates the issue of seedling blight, making application of a fungicide seed treatment such as Redigo M more critical.

Alternatives

Current alternatives include the use of bird scarers, with the accompanying noise pollution, or control of corvids by shooting; neither of which make sense in today’s agriculture.

The danger is that farmers and growers turn away from the growing of forage maize, a high-density nutritious feedstock both for the dairy and livestock sectors, and for the anaerobic digestion industry for energy production.

What are we doing about it?

Limagrain, along with a number of other seed breeders have initiated a working group which has successfully galvanised the NFU, AIC and other parts of the industry into action. Letters to MPs, Select Committees and Ministers have either been sent or are in the process of being sent. Civil servants have been contacted and the media “activated”.

How You could Help

We are keen that as many MPs as possible are aware of this issue:

1. Complete this survey put together by the MGA and NIAB which will give a deeper insight into the issue and who it’s affecting

2. Would you consider writing to your local MP on this subject?

3. Can you raise the problem with their local NFU representatives?

4. Evidence: we are definitely on the hunt for photos of where untreated seed has been planted and anecdotes thereof. Have you seen this problem in action?

After last year’s cold and dry spring resulted in some meagre first cut crops of silage, livestock farmers are looking for ways to ensure their silage clamps are fully filled this autumn. One option, according to Limagrain’s Tim Richmond, is to grow more maize.

“The severity of last year’s poor grass yields was highlighted by the sight of livestock farmers harvesting the last flushes of grass

growth as late as October and even into November,” Mr Richmond comments. “The silage those crops yielded will have been of questionable nutritional value, but with purchased feed prices as high as they were farmers had to do whatever it took to ensure they had enough feed to see them through the winter. As such, they will understandably be keen to avoid a repeat this year.”

One option to mitigate the risks associated with another difficult spring is to grow more maize Mr Richmond explains: “A well-managed crop of maize will be less susceptible to the stresses which led to last year’s grass problems,” he states, “with modern maize varieties able to deliver strong yields even when the growing season is foreshortened by late drilling.”

Mr Richmond explains that the latest generation of maize varieties require 10% fewer heat units than their predecessors and can be drilled up the end of May. “Limagrain’s European maize breeding programme has focused on producing new varieties with improved vigour and which require fewer Ontario Heat Units to reach maturity earlier in the year.

“We also breed and select varieties based on their stability of performance and standing power under the varying conditions that the UK climate can throw at crops, with our vigorous UK trials programme ensuring we only bring to market those new varieties which are truly suited to local conditions.

“Varieties such as Gema, Prospect, Dignity and Trooper all have an FAO rating in the 160-180 range which means they can be drilled later and harvested sooner. And, despite requiring a shorter season to reach maturity, they can still reliably produce clamp-filling yields of 16.5-18.3tDM/ha, almost twice as much as most grass leys will produce in the same timeframe.”

These varieties will also deliver a higher energy yield Mr Richmond says: “For example, 10ha of Trooper (FAO 170) can be expected to produce around 180 tonnes of dry matter and could easily be the difference between having enough forage in the clamp and having to choose between restricting forage intakes or purchasing additional feed.

“But it’s not just dry matter yield or earliness of maturity that matters,” Tim continues. “Fifty percent of the energy in maize is stored in the stalk and leaves of the plant so it’s important to select a variety which is easily digested in the rumen. In older varieties, this vegetative material was harder for livestock to process so Limagrain’s maize breeding programme has focused on ensuring those same high-yielding varieties also deliver more readily available energy by breeding in improved cell wall digestibility (CWD).”

Mr Richmond concludes by stating that the inclusion of more maize into dairy and beef diets has the added advantage of supporting improved rumen function and encouraging greater feed intake which translates into better milk yields and improved daily live weight gains.

“Growing an early maturing variety also gives farmers the option to establish a successor crop in the autumn and for that crop to be used as an early source of fresh forage in the following spring,” he advises.

Last year’s testing weather conditions have brought into focus the challenges maize growers can face when trying to produce a high-yielding, nutritionally valuable crop.

With last year’s dry and hot conditions causing many crops to underperform and in the worst cases fail, Limagrain’s Tim Richmond and Neil Potts of Matford Arable share their thoughts on how to mitigate the effects of variable weather patterns, disease and pest-related stresses.

According to Tim Richmond, maize manager for Limagrain, the key factors to consider when planning for a successful maize crop are varietal agronomics, drilling depth and seedbed conditions, minimising the threat from pests, disease and birds, and ensuring the crop matures early enough to enable a timely harvest without risking excessive soil compaction, erosion or run-off.

“With weather patterns becoming increasingly volatile and difficult to predict, it pays more than ever to plan carefully for the season ahead to ensure maize crops stand the best chance of achieving their true potential in terms of yield and energy content,” Mr Richmond explains.

“What last year’s excessively hot and arid conditions taught us is that it’s crucial to get crops off to a strong start so they are better able to cope with stresses later in the season.

“Growers should therefore select the most appropriate variety for their specific location and preferably one which has been tested and proven in UK conditions.”

“Factors including available heat (measured in Ontario Heat Units) and average rainfall will dictate whether a ‘very early’ variety such as Prospect, an ‘early’ variety such as Saxon or an ‘intermediate’ maturing variety such as LG31207 should be grown”.

“That’s as true for maize grown for ensiling as it is for crimped or grain maize and for crops destined for biogas production, but there’s never any guarantee the season will pan out as expected. Therefore, to give the selected variety the best start, additional care is required at drilling and during the establishment phase.

Mr Richmond explains that drilling should only commence once the soil temperature has reached 10^oC for at least four consecutive days and when the medium-term forecast looks favourable, “so seed germinates quickly and plants grow away strongly. Crops should also be drilled into well-aerated soils as maize won’t thrive in compacted soils where oxygen is limited. A starter fertiliser – applied with the seed at drilling – will also help the crop to grow away quickly.”

How crops coped during last year’s drought came down to how they fared during the establishment phase Mr Richmond adds: “Crops drilled into a warm, well-aerated seedbed with a decent amount of retained moisture rapidly put down strong roots which helped them to cope with the ensuing dry conditions and allowed them to develop an early canopy which helped to out-compete and suppress weeds”.

“In contrast, those crops which went into drier ground, either as a result of poor timing, lack of rainfall or where heavy cultivation had caused excessive moisture losses, failed to put down a decent root and suffered more as the dry conditions took hold.”

In terms of specific agronomic traits, Mr Richmond recommends looking not just at the usual performance indicators – dry matter yield and starch content – but at additional factors including early vigour, lodging ratings, disease resistance and maturity classification.

“Irrespective of the crop’s end-use, there’s no point chasing outright yield if the crop doesn’t contain enough metabolisable energy or if it grows too tall for its root structure and ends up lodging. A variety which puts down strong roots stands a better chance of remaining upright and will also be able to grow away more quickly and withstand dry conditions for longer thanks to the ability to scavenge water and nutrients from depth.

“Likewise, a crop with natural resistance to diseases such as stalk rot (Fusarium graminearum) will also be easier to grow, although it will still pay to manage disease carefully, particularly if the season turns out to be less than ideal.”

Neil Potts of Matford Arable agrees, stating that cool and humid conditions will aggravate the threat of disease. “Thankfully, the cool, damp conditions which exacerbate diseases have been relatively scarce in recent years, but it still pays to be aware of the risk especially as fusarium can be tricky to control once it has taken hold. It therefore makes sense to thoroughly bury the previous crop’s stubbles and debris to reduce diseases from over-wintering and to have plans in place should a fungicide application be required.

“In recent years, the drive to reduce costs has resulted in a small but significant groundswell towards establishing maize either via direct drilling or minimum tillage. In a favourable year these techniques work reasonably well, although the resulting crops can be a little smaller than their conventional counterparts. It is worth noting however, that last year’s conditions proved too much for reduced tillage crops in the driest parts of the UK which struggled because of their less-developed root systems and because many of the drills used didn’t have the ability to apply a seedbed fertiliser.”

Seed treatments and biological growth enhancers can also help to mitigate the effects of a poor season: “With feed prices remaining high the value of home-grown forage has also risen,” Mr Richmond continues. “It therefore pays to protect crops from the very outset, with seed treatments such as Korit Pro which, as well as repelling birds and protecting against damping off diseases such as pythium, also provides manganese and zinc to improve crop emergence and establishment through the susceptible 2-6 leaf period. It also contains a plant growth promoting rhizobacteria (PGPR) which colonises the rootzone and aids nutrient uptake, thereby giving plants a healthier start.

“Ultimately, the key factor affecting how a crop performs at harvest is how well it was managed in its infancy,” Mr Richmond concludes. “It’s therefore essential to do everything possible to get crops off to a vigorous start so that they stand a better chance of coping with whatever the season might subsequently throw at them.”

Maize growers can boost the contribution their crops make to their farm’s bottom line by using the free Maize Manager App from LG Seeds to select the most appropriate varieties for their specific use and location.

Suitable for Android and iOS phones, the easy-to-use app is designed to help growers maximise the performance of their maize crops and offset the cost of purchased feed.

“When it comes to choosing which variety to grow, the first port of call should be to study the independent data provided by the BSPB/NIAB Forage Maize Descriptive List,” explains LG Seeds maize manager, Tim Richmond. “Beyond that growers can also use the free LG Seeds Maize Manager App to determine which variety or varieties are best suited to their specific location and to ensure their 2023 crop delivers a reliable return on investment.”

The Maize Manager App uses the latest trials data and compares the energy output and milk, meat or biogas production potential of individual varieties within a similar maturity range to simplify the decision about which variety to grow for forage, grain or AD purposes.

“The Maturity Manager tool within the App uses postcode-specific Met Office data to calculate Ontario Heat Unit accumulations for the specified location and processes this information to recommend relevant varieties,” Mr Richmond says. “In doing so, growers can select the optimum variety for their location and purpose.”

The App’s Feed Value Manager tool enables users to calculate how much their chosen variety will save by offsetting purchased feed costs either as result of the variety’s ability to increase milk output from home-grown forage, or in the case of beef rearers and AD plants, how much the chosen variety will contribute to improved daily liveweight gains or increased biogas output.

The App also features a tool which helps growers to calculate the optimum seeding rate for their chosen variety, and one which determines the optimum date for harvest. It also contains a new LG Animal Nutrition (LGAN) tool which highlights the cost savings associated with using one of these high yielding, high energy varieties – either in terms of increased milk yields, higher liveweight gains or increased biogas (AD) output.

Richard Camplin, Technical Manager

According to Richard Camplin, LG Seeds Technical Manager, farmers who are able to grow maize, or who can work in partnership with an arable neighbour who is happy to grow the crop could benefit from increasing the acreage grown this year.

“There is still time to get maize in the ground and it could be used to increase forage output with reduced reliance on fertiliser. Maize requires less fertiliser per tonne of dry matter than grass and a large proportion on maize requirements can be met from slurry.

“Alternatively, it could be used to produce crimped maize to help trim the requirement for purchased starch sources. Careful variety selection can allow a degree of flexibility to be retained about how crops are utilised as the season unfolds.”

He says advances in plant breeding mean there have been massive improvements in the standing ability and disease resistance. New hybrids such as Prospect, Pinnacle and Resolute now have the combination of improved agronomy plus the advantages of superior digestibility and high starch yield, making them ideal for quality forage and also for crimping.”

If 2022 is a better than average grass growing season so grass silage yields are higher and if maize crops grow well, Mr Camplin the situation might develop where a proportion of the maize could be crimped to help reduce the requirement for purchased starch sources for the TMR.

Crimped maize is typically a 65-75% dry matter feed with 14.0-14.5MJME/kgDM and 60-70% starch making it a valuable ingredient in diets. Having been processed prior to clamping, it is a rumen-friendly feed with a higher proportion of bypass starch.  It can be clamped or stored in AgBags.

LG Grain Trial, Leicestershire

LG has been running UK trials looking at crimping potential and Mr Camplin advises that variety choice allows flexibility of use to be a real option.

“We ran trials on three locations with an average 27.5% moisture at harvest with the wettest crops being 33%. As the crops are harvested around six weeks after silage would have been taken, it is vital to be growing early maturing varieties and to allow the maximum growing season. So I would recommend not making crimp from later drilled crops.

“Early maturing varieties that performed best in the trials are LG30179, Prospect, Resolute and Pinnacle, so growing these varieties would give the option for quality forage or a crimped crop (see table).”

He stresses the importance of selecting a variety suited to the farm and to look for varieties with low levels of disease and high standing ability and lodging resistance. As crops are harvested later it is essential they stand well.  Bad infections of fusarium, for example, can lead to fusarium stalk rot which can weaken the stem and increase the lodging risk.

If a crop is being planted specifically for crimped maize, he advises it is usual to reduce the seed rate to 85,000 seeds/ha. This is primarily to help bring maturity forward but this is less of a concern if an early variety has been chosen as they tend to have good cob maturity. However, having more space and light will help improve cob size and starch content.

“If a grower is interested in growing a crop guaranteed to produce high quality forage but which could be switched successfully into crimping to maximise the contribution from maize the key will be choosing an early maturing variety with good feed quality and the best agronomics.

“In this way, maize can provide a flexible way to meet the challenges of feeding cows this winter,” Mr Camplin concludes.

Maize was often seen as a challenging crop to grow due to the late harvest. However, new earlier maturing varieties mean the crop can fit very well into rotations, allowing successor crops to be drilled in good

 conditions and in good time.

While not a full alternative to oilseed rape, which will usually provide a better return on investment in most years, maize can be incorporated into rotations as a way to increase the break crop area and leave a good margin.

Agronomically, maize can prove particularly effective on farms wanting to control problematic weeds like blackgrass. The crucial thing to look for is early maturing varieties that will suit your site’s conditions, as you need a variety which will mature at the right rate for your farm to ensure a timely harvest and successful establishment of a successor crop.

Try our OHU Calculator to find the right variety for your location

Maize maturity is all about heat, which is expressed as Ontario Heat Units (OHU). Maize needs to accumulate a minimum of 2500 OHU, before being fit to harvest. The fewer OHU required, the earlier a crop will be ready to harvest.

Earliness is defined by the FAO for the variety; earlier varieties have a lower FAO. They can be ready to harvest as much as two weeks earlier than later maturing ones, which can make a big difference to crop success. If you have a shorter growing season, selecting an earlier variety will reduce the risk of variable weather delaying harvest and will increase the chance of the successor crop being established.

Look for varieties with an FAO of 140-220, to ensure you get a variety that will mature in good time. Varieties like Resolute, Saxon and Mantilla, all combine early maturity with excellent yields, while Gema with an FAO of 150, is very early maturing. To simplify variety choice for your site, download our unique Maize Manager App, available free on the Apple or Google Play stores!

The Maturity Manager section was developed with data from the Met Office. It shows the average heat units for your postcode and then lists varieties which are suited to your farm, and will mature within the average accumulated OHU. The Maturity Manager will allow you to make an informed choice and select the optimum variety – reducing risk, ensuring an effective break crop and the establishment of the successor crop.

Whether you’re growing maize for high milk yields from your dairy herd, or exceptional performance from an anaerobic digester, you need the same thing – a high yield of a high energy variety. Look no further than LGAN varieties.

Check out the new LGAN section in the app!

LGAN varieties are bred to unleash the 50% of energy which is stored in the vegetative parts of the maize plant. By being bred for higher cell wall digestibility (CWD), this energy is more readily accessible than in other varieties.

Combining higher CWD with high starch content is the recipe for better quality, more productive crops.

Independent trials show that LGAN varieties produce higher intakes of more digestible feeds leading to:

• Increased milk yields
• Higher liveweight gains
• Increased gas output

All this means more money from forage and lower purchased feed costs.

Watch our brand-new video below which explains how LGAN varieties can boost energy yield from your crop.

Then download the LG Maize Manager app to identify the LGAN variety that gives you the most profitable performance.
