Choosing the right maize variety BSPB/NIAB Maize Descriptive List Trial SitesWith well over 60 maize varieties available in the marketplace, thechoice can sometimes be overwhelming.So which varieties are going to be right for you? It depends on a number of factors: yourlocation – whether a favourable growing area or not, the field conditions, growing system,and also, how soon you expect to harvest the crop.

Maize crops need to reach maturity in time for harvest if their full energypotential is to be obtained. To help you focus on the varieties of asuitable early maturity for a given growing area and sowingdate, Limagrain UK has developed its own MaturityGroupings, dividing varieties into one of three categories- Late, Early and Very Early (see page 1).

In livestock rations, the proportion of maize fed in theforage component also determines variety choice –i.e. whether starch or ME yield is more important.

To help guide decisions, the forage maize data ispresented in three different ways – ranked forearliness, for starch yield and for metabolisableenergy (ME) yield (see pages 2 and 3).

This Variety Selection Guide includes performancedata on all varieties on the 2015 NIAB DescriptiveList for Forage Maize and the new BSPB/NIABAnaerobic Digestion List. It also includes trial resultsfrom independent and some of Limagrain's own trials.

We hope you will find this Guide useful in helping youmake an informed decision on which maize varieties will bestsuit your growing conditions and end needs.

Having selected the appropriate LG Maturity Group and NIAB List to use from the LG Maturity Group Selector on page 1, the next step is to evaluate the varieties available for the bestagronomic and quality profile for your situation. The tables on the following pages provide detailed data on all the agronomic and quality characters recorded in the official NIAB trials.The scattergrams display the key information and provide easy at-a-glance comparisons between varieties. An explanation of how to use the scattergrams and tables is given below.

Step 2: Using the NIAB Data Tables & Scattergrams

Requires earlyApril sowing on only thebest sites, resulting in alater harvest with:

• High dry matter yield

• Low dry matter content

• Lower starch content

LATE

Usually sown on moremarginal sites in May, resulting in anearlier harvest with:

• Assured 32% dry matter content

• High starch content and yield

• Opportunity to sow an autumn crop

VERY EARLYUsually sownlater in April on goodsites, resulting in an earlyharvest with:

• High dry matter yield

• Very good feeding quality

Yield DataDry matter yieldEarlier varieties ensure crop maturity isreached, but tend to have lower yields thanlater types.

Dry matter content (%)Choosing a variety that can mature to 32%DM by harvest will ensure cob maturity andtotal yield potential is reached.

Figures range from 29% to 40% with theaverage in the 2015 Less Favourable Listbeing 33.5%. The higher the dry mattercontent of a variety, the earlier it will mature.

Agronomic DataEarly vigourA strong, vigorous plant will quickly establisha good root system and develop good leafsurface area to maximise photosynthesis andalso shade out any weeds below.

Standing When sowing maize it is important thatplants will remain standing without havinglodged before harvest.

Leaf senescence A variety should remain green and healthyup to harvest. Only select varieties with ascore above 6.0.Varieties with a lower score may suffer fromFusarium, which causes the plant to ‘die off’early.

Eyespot rating A high score indicates a lower level of diseasesusceptibility. Varieties with a lowersusceptibility may be selected for use in areaswhere the disease is more common.Selecting a variety with the correct yield,quality and earliness for the farm shouldalways take precedence, as fungicide sprayscan be applied in cases of high levels ofinfection.

Starch DataStarch yieldStarch yield is the total quantity of starchproduced per hectare. Varieties areranked by starch yield to see the relativeperformance of different varieties for thischaracteristic.

Starch % at harvestVarieties with a high starch content areespecially important in rations with alower percentage of maize fed (<50%).Maize starch balances the rapidlyavailable energy and higher proteinlevels found in the grass silage.

Why is starch important?Starch is a fundamental component ofmaize silage providing ‘rumenfermentable energy’ which fuels themicrobial population in the rumen. A proportion of starch is also absorbeddirectly by the animal as glucose. Maizestarch is a ‘safer’ source of energy thanfeed ingredients such as cereals, asfermentation rates can be slower,reducing the risk of acidosis.

Energy DataME yieldME is most important in rations with ahigh maize silage inclusion rate.Varieties in this table are ranked by ME yield.

ME (MJ/kg)Growers looking to improve feedingperformance and animal outputshould consider the energy value inmega-joules (MJ) of each 1kg of drymatter of silage produced. It is directlyaffected by the starch content andfibre digestibility of the plant.

Digestibility DataCell wall digestibilityFor growers feeding a high level ofmaize in the ration (>60%) it isimportant to consider how muchenergy can be derived from the part ofthe plant that is not starch, i.e. thestover (leaves and stem). The digestibility of the stover isindicated by the cell wall digestibility(CWD) score.

CWD figures are expressed by NIAB asa percentage. However, in thisLimagrain guide, CWD values havebeen converted to a simpler range of4.3 to 8.7, with each increase of 1 unitrepresenting an increase of 1% in cellwall digestibility.

Using plastic coverThe ‘under plastic’ system was developed inIreland to enable farmers in the more marginalareas to grow maize successfully. In the UK, it canbe of benefit in advancing crop maturity in verymarginal areas, such as Scotland and areas ofhigh altitude in the south west of England andnorth Wales.

The plastic cover enables sowing to start earlier –at a soil temperature of 6°C, as it creates a‘greenhouse’ effect so maize seeds can germinateand become established during periods of coldtemperatures and frost. In addition, it increasesthe total heat accumulation of the growing crop,and brings forward maturity. This allowsharvesting to take place earlier, and/or allowstime for a follow-on crop to be sown.

AgronomyPlastic cover does add an extra growing cost ofaround £250/hectare. This is partially offset bythe use of a lower seed rate of 100,000 seeds/ha(40,000 seeds/acre).

Good weed control prior to sowing is vital. A pre-emergence herbicide spray is applied at time ofsowing but after this, options are limited due tothe plastic cover.

Variety selection for forage maizegrown under plasticCurrently, the only independent source ofpublished data on how maize varieties performunder plastic is DAFM (Department ofAgriculture, Food and the Marine) in Ireland. Thelater maturing LG variety Award is fullyrecommended by DAFM for use in plasticcovered systems, and provides an improvedquality alternative to Justina.

UK TrialsOver the past five years, Limagrain has been carrying out plastic trials at sites inthe midlands and south west of England and at the SAC in Scotland. Resultsshow that although all varieties can grow through plastic, performance doesvary. Varieties – Ambition, Asgaard, Award, LG30.211 and Yukon have proventhemselves, both in these trials, and also commercially.

# Limagrain estimated days earlier to harvestthan Marco - the latest variety on theFavourable NIAB List.

Yield DataDry matter yieldEarlier maturing varieties help ensure cropmaturity is reached, but tend to have loweryields than later types.Dry matter content (%)Choosing a variety that can mature to 32% DMby harvest, will ensure cob maturity and totalyield potential is reached.NIAB figures range from 29% to 40% with theaverage in the 2015 Favourable List being32.9%. The higher the dry matter content of avariety, the earlier it will mature.

Agronomic DataEarly vigourA strong, vigorous plant will quickly establish agood root system, and develop good leafsurface area to maximise photosynthesis andalso shade out any weeds below.Standing When sowing maize it is important that plantswill remain standing without having lodgedbefore harvest. Leaf senescence A variety should remain green and healthy upto harvest. Only select varieties with a score of6.5 and above.Varieties with a lower score may suffer fromFusarium causing the plant to ‘die off’ early.Eyespot rating A high score indicates a lower level of diseasesusceptibility. Varieties with a lowersusceptibility may be selected for use in areaswhere the disease is more common. Selectinga variety with the correct yield, quality andearliness for the farm should always takeprecedence, as fungicide sprays can be appliedin cases of high levels of infection.

Starch DataStarch yieldStarch yield is the total quantity of starchproduced per hectare. Varieties areranked by Starch Yield to see the relativeperformance of different varieties for thischaracteristic.

Starch % at harvestVarieties with a high starch content areespecially important in rations with alower percentage of maize fed (<50%).

Maize starch balances the rapidlyavailable energy and higher proteinlevels found in the grass silage.

Why is starch important?Starch is a fundamental component ofmaize silage providing ‘rumenfermentable energy’ which fuels themicrobial population in the rumen.

A proportion of starch is also absorbeddirectly by the animal as glucose. Maizestarch is a ‘safer’ source of energy thanfeed ingredients such as cereals, asfermentation rates can be slower,reducing the risk of acidosis.

Energy DataME yieldME is most important in rations with highmaize silage inclusion rates. Varieties inthis table are ranked by ME yield.

ME contentGrowers looking to improve feedingperformance and animal output shouldconsider the energy value in mega-joules(MJ) of each 1kg of dry matter of silageproduced. It is directly affected by thestarch content and fibre digestibility ofthe plant.

Digestibility DataCell wall digestibilityFor growers feeding a high level of maizein the ration (>60%) it is important toconsider how much energy can bederived from the part of the plant that isnot starch, i.e. the stover (leaves andstem).

The digestibility of the stover is indicatedby the cell wall digestibility (CWD) score.

CWD figures are expressed by NIAB as apercentage. However, in this Limagrainguide, CWD values have been convertedto a simpler range of 4.8 to 10.5, with eachincrease of 1 unit representing an increaseof 1% in cell wall digestibility.

Maize for Crimping or Grain Maize crops can be combined for their grain (cobkernels), from which crimped maize or dried graincan be produced.

Growing maize for grain is an attractive cash cropoption, and for arable farmers has the added benefitof breaking the cereals rotation, giving anopportunity to reduce blackgrass populations.

Danish Farmers’ Union Grain Trial ResultsDenmark has similar growing conditions to the UK with an increasingarea grown for grain maize. The Danish Farmers’ Union (DFU) conductsextensive independent variety trials. In these, three LG varieties -Ambition, Yukon and Glory - have produced high grain yieldsdemonstrating their suitability for both grain and crimping use.

Opportunities for grain and crimped maizeThere are two main uses for grain maize:

1. Dried grain maize for use in the bird and pet foodindustry. This small specialised market demandsvarieties with attractive yellow kernels.

2. Moist crimped grain maize for livestock feeding.For this larger market, maize grains are treated with a preservative to create a moist anddigestible high energy feedstuff with ametabolisable energy content of 14.0-14.5 MJ/kg DM.

In the UK, grain maize yields are around 8t/ha of DM, giving a crimped maize output potential of12t/ha (@ 65% DM).

Variety selection for grain andcrimping useTo harvest maize for grain the crop needs to reach amoisture content of 25-35% (DM of 65-75%) beforebeing combined. This means it is left longer in thefield than forage maize crops.

So, the main criteria when choosing which varietiesto grow for grain or crimped maize are earliness andyield. It is a high risk strategy to grow later maturingvarieties, even though DM yields may be high.

Since grain maize crops remain in the field for alonger period, varieties need to have good standingpower and also good cob cover - this reduces theirsusceptibility to Fusarium infection (and probability ofmycotoxins forming). * Selected varieties with two years of results

The role of maize as a feedstockTo maximise the production efficiency of anaerobic digestion (AD)plants, it is important that the feedstock used is consistent. Thisenables maintenance of the optimum environment for themicroorganisms and ensures a stable gas output. Maize forms thebase feedstock for most on-farm AD plants as it is consistent interms of supply and physical qualities, enabling a homogenousmix to be maintained.

The best crops for using as a feedstock are those which canproduce a large volume of gas per hectare.Maize has the potential to produce veryhigh yields of an energy dense crop andwhen used as a feedstock producesthe greatest amount of biogas perhectare of any crop. With relativelylow inputs and a high energy output,maize is excellent value in terms of itscost per tonne of dry matter.

The combination of improved cell walldigestibility, top ME content and high yieldsmake Atrium an ideal feedstock.

High yield and good ME content.

ASGAARDAn exciting new variety which combines earlymaturity with very high ME yield and content.

An earlier high ME yielding option to helpspread harvest cutting dates.

Early maturing with a very high ME yield,enabling an earlier harvest withoutsignificant yield loss, and a follow-on crop tobe sown sooner.

A blend of two varieties chosen for theirperformance for AD production from our maizescreening trials.

One of the highest yielding varieties availablefor biogas use. Already widely used on biogasplants across northern Europe.

Maize variety selection for biogas productionMaize can be successfully grown in most areas of the UK, but it is importantto choose varieties suited to the growing conditions of your farm. Largeareas of maize are needed for an AD plant, for example a 500KW anaerobicdigester requires approximately 220ha of maize silage. So to make it moremanageable to harvest all of the crop at the correct dry matter, it isrecommended that varieties with different rates of maturity are sown, inorder to spread the harvest window.

Varieties should be selected which will reach maturity early enough to allowharvesting before wet weather sets in to avoid soil structure damage. Thetarget dry matter content at harvest is 28-32%.

LG Maize varieties for anaerobic digestersThe extensive UK-based Limagrain research programme tests potential newvarieties at trial sites spread across the country and on working AD plants. A vigorous selection process ensures that only the very best varieties are available to growers.

* Limagrain estimated days earlier to harvest than LG30.223 the latest variety on the AD Favourable List.

A new ‘Maize for Anaerobic Digestion List’ is available to provide AD (anaerobicdigestion) plant operators and growers with independent data to use whenselecting varieties to maximise biogas (methane) production.

This List has been compiled from over 3 years of independent BSPB/NIAB trialdata and recognises that the selection criteria for anaerobic digesters are differentfrom those for livestock feeding. When selecting varieties to maximise theproduction of biogas, the best indication of their potential is the total energy (ME)yield per hectare.

As with the List for forage maize, information on variety performance is providedfor sites which are Favourable and Less Favourable. On this page, the FavourableList is shown, as most AD plants are in good growing areas. Further informationfor Less Favourable sites can be found at www.lgseeds.co.uk/maize
