Weather issues!

Well most of us have and are having to deal with weather issues, most likely for the next 18 months as the after effects of this years weather ease their way through the next cropping year. What do I mean by this, well it matters little what crop you are growing, whether grass or arable, compaction and subsoil damage from stock and machinery will have been considerable this year and these are very noticeable in autumn sown crops already this year and will be evident in grass growth rates in the spring.

About 40% of autumn crops are in the ground down here in the Southwest, a large amount of grass reseeding never got done because the ground conditions were poor too and any Oilseed Rape that was drilled has sustained a prolonged spell of attack from slugs and what is left is now being piled into by pigeons en masse!

To top it all, spring cereal options are now difficult with the chronic lack of spring cereal seed available.  I am not panicking yet as I think there will be seed coming available after new year that has been ordered on the proviso the wheat that was planned is not drilled. I know a lot will say that because the ground is now so wet, there is no chance in hell of it being dry enough to drill by the beginning of February. I remember clearly the statements earlier in 2012 about it taking years to recover the subsurface moisture deficits in much of England due the extreme drought conditions, look where we are now 7 months down the track. If we get this very cold weather that some forecasters are predicting, winter ploughing and late drilling winter wheat is still an option, especially any varieties with Claire in their parentage. Last year we were drilling Istabraq on ground at 800ft on the 1st of March and it still yielded more than all the earlier drilled stuff.

So don't panic, there is time yet still to get winter wheat in the ground, we still have a lot of weather to go through before spring and hopefully that which is planted will have a deep enough root system to survive while the cold weather kills off the slug problem and does something to remedy the soil structure issues. Just remember to raise the drilling rates up towards the 450 seeds/sqm level to account for higher seed mortality and reduced tiller numbers and don't drill too deep!

Maize thoughts

I know a lot of maize growers this year are probably thinking about whether it is the crop they should be growing, or thinking about reducing their acreage grown, or thinking why they decided to grow it in the first place. Yes it has been a really difficult year for maize growers, certainly down here in the south west, but then looking at wheat whole crop results and seeing starch levels down as low as 12%, you question the wisdom of relying on this as a starch source too. The same rules that apply to getting a good crop of wheat apply to growing a good crop of maize, namely good seedbeds, the right fertility, the right field aspect and a whole lot of SUNSHINE! Without the later, nothing grows, as can be seen with grass growth as well this year.

The vital thing now when looking at harvesting maize is to make sure the crop is as fit as possible before going into the clamp, cutting maize below 20% DM is really asking for a lot of trouble when it comes to be fed, the acid loading from the sap and sugars that convert into acid during the fermentation process will be off the richter scale, making for some very unhappy animals that are forced to eat it. Not to mention the potential environmental concerns of trying to control and store, dispose of all the effluent that is likely to pour out the bottom of the clamp.

A crop that has been re-drilled, showing the most yellow cob with the most starch, though only at about 20%DM.  The re-drilled stuff has a long way to go before it's ready to be ensiled.

A really good crop of maize (for this year), but at least 10 days away from being ready to cut. Taking this early will decimate all the hard work and add to the woes of trying to feed it successfully this coming winter.
This crop was at 30% DM, can see the die back in the plants, the sheaves on the cobs have started to brown off and the grains were firm with little milk in them. It may only be an 8 ton crop, but at least all of it will be utilisable. The cows will milk better off this than the crop above if ensiled at this stage.

It's despairing when you see fields as wet as this, this late in the year, the temptation is so strong to go and get the crop on a dryish day, but patience will give a better result.


 Maize under plastic this year seems to have been very variable, it certainly isn't the magic bullet to growing good maize, some very early drilled stuff rotted under the sheets, other stuff never got going as the soil temperatures were too low for adequate mineralisation of nutrients to take place. Those that planted late April and into May however did get some reasonable crops, however due to the low levels of sunlight, they have faced a nightmare trying to cut the crops without dragging up big pieces of plastic into the foragers as there hasn't been enough sunlight for it all to break down.

There are some things we can do however to improve the agronomy aspect of growing maize here in this part of the world. The issue is we have to get contractors and growers likewise to take it forward, as  contractors are heavily invested in the status quo at present.

Inter-row cultivation with something like this in the picture link below is what I have used very successfully in Zimbabwe in a pre-post-emergence herbicide application situation up to about 6 leaf stage. It is very useful where the soil has capped off after a heavy downpour and the soil has slumped a bit, destroys any young weeds, aerates the soil and can be configured to through the soil towards the plants, or into the middle of the row. It works tremendously well in combination with a post emergence fertiliser application as you can 'brush' the nitrogen in towards the roots, making the uptake and utilisation far better. The other beauty of these machines is they are light and don't require a lot of horsepower (and weight) to pull them.

Strip tillage / Rip-on-row tillage is another way we can get maize established, a very well documented and proven form of growing maize in both the southern hemisphere as well as the USA is slowly making an appearance here in the UK, but the machinery looks really expensive and requires a lot of horsepower to pull. There are simpler and less costly manufacturers about.
http://www.seeddaily.com/reports/Strip_till_improves_nutrient_uptake_and_yield_999.html

We also need to look at these types of planters to maximise sunlight availability per plant, whilst maximising nutrient uptake too. I saw one of these in the Freestate last December and the maize planted this way was noticeable healthier, further forward with thicker stems than that drilled conventionally. The farmer reckoned he was seeing a least a 10% grain yield advantage, in some cases up to 20% or more. I know Great-plains (Simba) have a machine here in UK, they have done some work with it this year, but I haven't yet been able to see how well it went. The link below is the machine I saw.

All food for thought.

Wheat Demo Plots 2012

The two sites, one at Tregony and the other at Bude had very contrasting starts this last season.

Tregony followed Winter Oats and was drilled by the 10th October in relatively good conditions at a seed rate of 64kg/ac (158kg/Ha) and had a good start with the mild and albeit wet conditions through till Christmas. Bude on the other hand followed grain maize in part of an oilseed rape field, which came off mid October. However, the heavens then opened and the stova on the surface acted as a lovely mulch retaining all this moisture. The situation was worsened by the fact that a Simba cultipress had disced the stalks just after cutting with the result the land became like a sponge and nothing could move on it till we got a lucky break mid November when we managed to get a plough in and sowed the plots right behind using a light tractor with a 3m triple K type cultivator and air drill. Even so, there were wet areas where we had to lift the implement out of the ground almost in order to get through without getting stuck.

The above photo shows the thin looking Stigg (more brown than green) with JB Diego (New seed) on the left of the dividing strip and farm-saved JB Diego on the right. Ignore the very green headland which is Nickerson Original Invicta seed, look closely at the establishment of the JB Diego. The new seed has established far better with a denser plant number, is more vigorous in its growth at this early stage, something that would continue right through the plots lifespan.
Edgar, a new variety bred by Limagrain in Germany and a useful Group 1 milling variety was in the demo to see how well it might fair down in wet and wild Cornwall. It was the greenest all through winter, well established and very clean. It has a disease rating similar to Alchemy with similar yield. It is the very dark green plot, with Solstice on it's left and Exsept on it's right and Crusoe, a new group 1 in the foreground. The photo below shows the difference between Invicta and Alchemy coming through the winter, Invicta had much more biomass and leaf area, Alchemy much more prone and prostrate.



The three plots visible below are left to right Istabraq (low vigour seed and looking thin), Gravitas and Horatio to right of the central divide and Avatar below it. Gravitas had a low Thousand Grain Weight TGW, so looks very thick, Horatio looked well and green through out the winter. Avatar is just visible to the right of the Horatio.



The Bude plots by contrast looked quite rough given the way it was mauled in.

The late planting proves that sowing low vigour seed is not a good idea! It was a struggle to do plant counts in the Istabraq plot, Stigg also was not looking happy, so can safely say this is not a variety to drill late!


However, by the end of March they had started to pull together remarkably well. The Edgar still looking very green compared to all the rest as can be seen below.


By May, the Istabraq plot that had looked bare looked like this, a transformation, as it tillered like mad with some plants having 20 plus tillers. This was really surprising as this would have been ploughed in in normal circumstances to establish a spring crop.

By May, the Edgar was showing just what a huge plant relative to everything else it is, very noticeable with the thick wide chord leaves. This photo I took up at Bury St Edmunds shows this clearly.

I held two open days this year at both venues, the main ones being the 5th and 12th of July, first at Bude, then Tregony. The Bude day was well attended with 60 people attending during the course of the day to look at the Wheat and Oilseed Rape plots. Alastair Moore, Nickerson Sales Director was in attendance and gave everyone a frank and well appreciated appraisal of what was happening with the varieties, as well as in the wider grain areas to the north. It was really useful having a large scale cereal growers' perspective on the risk versus reward of varieties, how spray costs this year were making such a dent in farm budgets and what the wet weather was doing to potential yield estimates. 


Finally, on the last day of August, we managed to harvest/salvage the wheat plots at Bude, with the ones at Tregony done a week later. Here are the videos of both demo plots just prior to them being cut, this gives you a fairly accurate idea of how well these varieties stood up to this years conditions.




I am trying to get the results into a format I can post on here, so far it is not like excel or pdf files!

Playing Russian Roulette

For a fortunate few, Harvest 2012 is drawing to a protracted and very difficult close, certainly this is a year that we aren't going to forget in a hurry!

It has been a revelation this year, a 'shake out' year as one of our breeders described it, as some serious issues that potentially threaten wheat breeding program's are starting to emerge with some very serious consequences for UK farming.

In the past some breeding program's have focused on genetic resistance to regular disease pressures, septoria tritici being the main one, with other traits being bolted on. Some other breeders have been focusing on all out yield, regardless of how genetically strong these varieties were, their consensus being that disease risk could be managed by chemistry tailored to curb disease outbreaks. Barn filling varieties with poor to average disease traits proliferated as farmers bought into the idea that chemistry could solve all disease problems. As with anything in nature, disease pressures and mutations give rise to new challenges. Single gene resistance to disease instead of dual, or multiple gene resistance is easier to breed into new varieties and allows quick turn around from lab to field. As a consequence we are now seeing multiple incidences of varieties succumbing  to Yellow Rust and Brown Rust strains that are evolving, varieties that have only just been registered on the HGCA recommended lists, with the resultant increase in usage of full blown ag-chem programs to try and control these issues.

Throw into this mix one of the wettest growing seasons, especially from pre flowering all the way to harvest with low solar energy levels, high humidity and very damp soil conditions and you have a perfect storm scenario for a whole host of new diseases to make their presence felt too, especially Fusarium which has quite literally sucked all yield out of wheats this year, apart from those like Istabraq that has not suffered as much and is still producing a reasonable sample.

A common theme I am hearing on farm is a new level of questioning with regard to ag-chem inputs, how expensive this last season has been to get a crop that basically isn't near covering costs. It's is interesting to note how some of these chemistry suppliers have gone from small scale operations to giants in the industry in a very short period of time, considering how long the 'green revolution' in agriculture has been going on for. In a very short time span, farmers have seen their supply base of agricultural chemicals diminish considerably down to just a handful of players in the market, with the agronomy angle reduced even further and geared almost exclusively to structured spray programs. In a wet year like this last one, total reliance on sprays to control disease has been severely tested and the basic fundamentals of genetic resistance and a variety's ability to cope under stress have been fully on display. Some have coped and a lot have not.

Soil science, I would say is one of the most important factors governing yield, has been largely forgotten, farmers have devolved responsibility in many areas to their ag-chem supplier and crop walkers who supposedly are more knowledgeable in maximising yields and thus returns on their behalf. The knowledge gap on farm has been further diminished as a result of squeezed margins in the 'naughties' that lead to farmers farming more acres with less personnel and thus being more time restricted to chase knowledge in this regard. Universities and Agricultural Colleges too reduced the soil science input and concentrated more on the chemistry and machinery aspects of tillage, horsepower and technology as soil science generally was considered boring by most students. How many modern day farmers really understand and know what is going on in their soils?

A common theme I hear on farm is this; "why is it that with all your new fancy varieties you are breeding I am still only getting the yields we were getting 10 years ago"? Well, this time I heard an answer that came from a soil specialist company that has been growing a database on soils across the UK for the last 10 plus years and what he said was scary. The basis of it is this, pure arable farmers have been depleting the soil organic matter for so long with simple cereal and rape rotations that in some areas these levels are so low as to be irreplaceable, the soils have had all the life sucked out of them and as a result they physically are unable to provide the growing crops with the nutrients to attain their genetic potential.

It really has been noticeable in fields this year, those with good organic matter, good structure, good nutrient status have still delivered a reasonable yield and machinery has still been able to travel at critical times without leaving 3ft deep ruts. A farmer I know in Wiltshire has been chopping his straw for 10 years now, been applying copious amounts of compost and maintaining his lime and nutrient status with almost religious zeal. On very heavy clay over chalk, he has managed to keep going during harvest when his neighbours were getting stuck, his fields have a natural 'sponginess' to them as you walk them with very few areas of standing water in any of them, whilst neighbours have had 6" across whole fields of standing water for long periods of time. When you look where the combine has been traveling, there are no deep ruts, look over the hedge and it looks like a battlefield.

The genetic potential of some of the older wheat varieties like Einstein is well in excess of 25t/ha, we know from data attained in New Zealand these varieties are currently doing 18t/ha on farm in places consistently where the fertility of the soils has been maintained and the soils well managed in terms of rotation, organic manure levels, trace element replacement and most importantly, soil structure. These farmers have good rotations with break crops designed to replace organic matter and recharge the soil nutrient levels, instead of relying on stuff out of a bag. UK farmers in the main have not been doing this and yield increases have largely flatlined.

We need a radicle rethink in how we manage crop rotations, increase soil organic matter levels, improve soil structure and rejuvinate trace element levels. We need to sometimes stop and think; the soils we are farming are the product of millions of years in the making, yet with our modern cropping methods we are depleting their ability to produce the very food that our growing populations will need in the future.

How are the future generations of young farmers going to produce a decent crop that provides an economic return if the very medium needed to grow it is barren? Those who think GM will gallantly ride to the rescue are sadly going to be disappointed because the focus in GM at present is geared towards mainly chemistry, rather than soils.

The last 5 years have in the main been benign to cereal varieties, yes there has been pressure from disease, but the weaker ones were still able to deliver a credible yield with a lot of ag-chem help. This year we hit chamber six and it has blown a huge hole in many a bottom line  Lets hope this year the HGCA clamps down on low disease threshold varieties whose presence on the list now is very questionable and we move away from 'spray and weigh' varieties.

A little glimmer of light amongst a tale of woe.

Speak to many westcountry farmers and the opinion is the same, we have never seen a 'summer' like this one, in fact the whole year has been pretty much up the spout with no let up in difficult conditions.

With harvest struggling on and the results looking far from brilliant so far, it is great to hear a success story, well success in part anyway. A while ago I put a short clip up on youtube where our Sales Director Alastair Moore and I were looking at the ins and outs of establishing Oilseed rape, the link to the clip is down below. Our Rape breeder has been saying for years that canopy management, establishment and nitrogen influence final yields much more so than the individual variety that are ranked on the HGCA 'descriptive' list (I call it descriptive, because some of the LSD numbers are so far out so as to make the results statistically null and void). We get shoehorned into chosing varieties according to their results on this list, which incidently through the way the data is gathered is automatically selecting for taller and later maturing varieties, not ideal given the conditions this year!

Last summer a variety called Artoga, bred by Limagrain, started to raise it's profile because it was doing stunningly well in large parts of Europe and was one of only a few varieties that proved it could survive bitterly cold conditions and produce a crop that doesn't readily shatter at harvest time. I persuaded a few of my customers to try it and lo and behold it does what it says on the can! One of my customers on really wet heavy and very marginal soils on the cornish border put some in with a Sumo, very late (late September) and although we had a mild autumn, the fact we had so much rain drowned quite a bit of it where water pooled and sat from November through till March. However, on the one field that is south facing and reasonably well drained it was stonkingly good. Considering as well that it didn't have an autumn herbicide, that it only had one fungicide spray during it whole lifetime, to end up with an average yield well over 1ton/ac is encouraging, given that some crops that have had everything thrown at them are only doing 1.5t/ac. To appreciate how much abuse it had, it was dessicated and then left a good 3 weeks enduring torrential rain and thunderstorms, with long spells and damp mizzle thrown in as well, followed by bursts of very steamy hot weather before the combine managed to get to it last weekend (11th August). The grower fearing the worst gingerly started cutting thinking that most of the seed would have dropped out, or worse would start shedding from the vibration of the cutter bar on the combine. I am happy to report his worries were unfounded; no lodging, no cutterbar losses, no shedding! 

Elsewhere we are seeing yields consinstently in the 1.55-1.8t/ac range down here, which given the conditions and the season is quite encouraging and certainly on a par or exceeding the yields of the high ranking varieties on the HGCA list.

At last something that backs up what I have been saying for a long time.

There is a lot of marketing hype that gets printed in the popular farming press, but I have to say this is one of the first articles I have read that talks common sense and puts the whole economic perspective of dairy farming in a neat concise article. It is something Simon Broddle of Nickersons has been saying too about over leafy, young, watery grass types that are being stuffed in grass mixes. They are out of balance with the animals needs, they may analyse well in a lab, but more often than not I am coming up against a common theme of the forages not feeding as well as they analyse.

Add to this the ever increasing issue we are brewing up in our soils highlighted here in easy to understand language, I hope that producers start looking at their soils in the manner they should be, as I have already highlighted in a previous post.

Farmers Guardian article December 2011

Taking a 'holistic' approach to dairy management is allowing better returns to be made.

Growing a specialist variety of grain maize , as well as lucerne and grass and managing it according to specific advice from leading forage experts Nickerson Direct has resulted in North Cornwall farmers Michael and Anthony Grills being able to consolidate and expand their dairy enterprise even in the face of price adversity.

Continuing pressure on the dairy industry has encouraged Michael and Anthony to focus on increasing efficiency and cost-effectiveness over the last few years, during which they have expanded their dairy business from 250 to 320 cows, with the eventual aim of reaching 500. They have also implemented major advances in genetics and nutrition, reduced costs, improved attention to detail and increased profitability.

Until 2009, cropping at West Trelay Farm, Marhamchurch included 60-80 acres of forage maize, which was included in the ration at the rate of one part to two parts grass silage. However, the Grills found it difficult to achieve consistently good results from forage maize and variability in the clamp made correct rationing difficult. Typical butterfat levels struggled to get to 4% on the wheat and barley mix as a starch source along with forage maize, which when on a cheese contract is costly.

In early 2009, Nickerson Direct Seed Specialist Simon Montgomery suggested that Michael and Anthony include grain maize with the forage maize as an additional energy source to supplement grass silage, its higher energy/starch content significantly improving milking performance and making the ration easier to manage throughout the year.

The initial crop produced an average of 5 tonnes per acre of grain which was put into the clamp for £68/t, making it very cost-effective. The maize fed tremendously well, with average butterfat content increasing from 3.98% to a maximum of 4.54% during the winter and never dropping below 4.2% the following summer, while protein remained at 3.18-3.21% throughout. The resulting increase in the quality of the milk, all of it contracted to Dairy Crest for cheese production, netted the Grills a 1p/litre quality premium worth £25,000 per year.

It was so successful that in 2010 they substituted the area of forage maize for grain maize, drilling 90 acres of Lorado between 18th and 21st April. The crop established quickly in favourable conditions, grew consistently throughout the season despite being subjected to severe drought stress and in terms of maturity behaved more like a Group 9 than its official NIAB Group 7 rating would suggest with harvest completed by 17th October and averaging a respectable 4.5 -5 t/ac in yield.

This year, the area was increased further, with a number of fields being 3rd year grain maize. 2011 started off far drier than 2010, with the crop being planted on the 14th and 15th April in ideal conditions. What was startling though on the light ground was how much moisture had been retained by the 2 previous years mulched stalks, allowing easy seed bed preparation and perfect planting conditions giving a very even plant establishment, something others struggled with this year. Herbicide applications also worked well. Even with the extremes of weather this year, first hot and dry, then cold and dry, followed by cool windy and wet conditions from 15th June onwards, the crop looked good.

By the 11th October the crop was ready to harvest, even after the poor growing conditions this year, with contractor Phil Strout combining 4 - 5 tonnes per acre (at 30-34% moisture) of what Anthony Grills describes as ‘a wonderful product, like gold dust’, although he acknowledges that their location on relatively dry ground in North Cornwall favours the crop. The fact that Lorado dries down quickly, right to the base of the kernel, 'enables us to put it through the crimper efficiently, producing a gritty flour type product, even though we are adding water with the acid type preservative, which as a result has increased surface area allowing easy digestion in the cows' gut. We're also getting better protein values from the maize as a result of using this method. In doing so we are reducing the overall acid loading on the cows digestive system, which with good quality grass silage is making a noticeable difference'.

After appraising and careful consideration with Simon, a trial field of Lucerne was planted in one of the drier fields 'to see what happens'. Simon's past experience of growing Lucerne in Zimbabwe helped in getting a fantastic establishment in difficult dry conditions. The first cut was made mid July, being left to wilt for 4 days with one turning with an old Vicon Acrobat doing the job very well without losing the leaf, before row up and baling. The Lucerne was chopped as being baled, resulting in very dense, tightly packed bales which had an additional layer of plastic to stop any 'porcupine effect'. The resultant forage has surpassed expectations. The second cut in early September was done the same way and has analysed equally well, yielding similarly at 8 600kg bales per acre. Next year, four cuts should be easily achievable.

                                               Sowing Lucerne near Bude, 15th April 2011


                                                 Establishment is everything with lucerne.
                                   Cutting and wilting properly, without loosing the leaves is critical
The inclusion of 1.5 kg per cow of Lucerne in the diet has raised protein levels from 3.18 to 3.35%. It has also allowed the removal 0.25kg per cow of soya from the ration, saving over £900/month in bought in soya cost. It has also helped boost butterfat levels which are now up to 4.64% in cows producing 10,000 litres of milk. The milk from forage figure is now standing at 4500 litres, from grazed grass and grass silage only, as the grain maize is treated as a concentrate.

What is noticeable too is how cow health is improving. Cows are very 'on the go'; alert, but contented and relaxed looking when you study them, they do not look tired and lethargic. They are showing better bulling signs and better holding post AI. As a result the cull cow numbers have reduced, calving index is improving, there is now a surplus of heifers being reared which is providing another good revenue stream to the business.

Soil management has also been appraised, some time ago soil conditioning fertilisers became part of the crop fertilising regime, recently the inclusion of 'bugs' into the slurry towers is enhancing nitrogen values by 18-20% with silage ground staying green after cutting, rather than the usual browning off period whilst swards recover. This has lead to a reduction in bought in Nitrogen fertiliser use over the whole farm, particularly in the grain maize fields, the flora and fauna levels in the soils as a result is improving along with soil structure.

The combination of crimped maize and Lucerne in the diet has added an additional 1.5p quality premium to their milk price, which is making the business far more viable. It is also providing the basis for a more balanced diet, with good quality grass silage under pinning it. 'Most importantly, the growing of grain maize at £70 per ton in the clamp, the improved milk price as a result of better quality milk, the savings from inclusion of Lucerne into the diet has stabilised the farm business, on the borrowings side and the new bank protocols, our business is more sound and is allowing us to push forward and further invest in our enterprise.

As Simon has said before, "Dry grain production requires varieties with rapid dry-down rates, harvested after the leaves have died back and typically followed by the removal of 10%-15% moisture in a dryer, which increases the cost of the final product and is a major factor in steering producers towards moist storage after crimping".

“The high energy content and slow starch degradation characteristics make crimped grain maize an ideal moist concentrate feed for high-performance dairy and beef animals. It is convenient and reliable, ideal for use on farms where maize silage area is limited but where additional starch is required in the diet. Typically, the nutrient analysis for crimped grain is 65%-75% Dry Matter, 12-13 ME, 9-11% crude protein and 60%-70% starch. What makes Lorado so good is that it typically has a protein value of 12.7%, much more than other varieties and this does make a big difference in the ration".

“Grain maize provides a much more concentrated form of energy than forage maize, which is very important in achieving the correct energy-density in rations, enabling cows to eat more and make more milk. It is also very convenient, allowing livestock farmers to ‘top up’ lower-quality forages and those who buy in straights to purchase the exact tonnage they require, as and when they need it, which benefits cash-flow.

“Many farmers have tried to produce grain maize using conventional forage varieties, but these will only dry down slowly to a minimum of 30% moisture, making the crop difficult to combine in often wet and windy conditions late in November or December. Growing specialist grain maize varieties will make a big difference, but producing a good crop requires a different technique in terms of variety, plant population, nitrogen management and timing".

“It is essential to choose the correct variety. Lorado was bred by Limagrain specifically to perform well in Northern Europe. It is one of the earliest-maturing varieties in the Maize Growers Association trials and under favourable conditions does not require covering with plastic. Despite being the tallest on the NIAB list, it has excellent standing power, good disease resistance, excellent early vigour and good cob tip cover, which eliminates the risk of mould infection from ‘snouting’. Lorado produces excellent yields of high-quality grain, has superb dry-down characteristics and will reach 25% moisture, making it easier to harvest.What growers don't always appreciate is that dry-down gets slower the later the crop gets into October, particularly when you start getting into November, whilst the ground and conditions typically are getting wetter! It sounds obvious, but I am seeing combines running down in the southwest in late November by which time white moulds, fusarium and cob rot are starting to really take hold. The whole idea should be to harvest as pure a form of starch as possible, yet by planting later maturing varieties, even under plastic, the resultant contamination risks are hugely increased, negating the advantages of inclusion in the diet. We are harvesting Lorado at Bude before most of the forage varieties are harvested, which gives some idea of just how early to mature it is".

“Grain maize crops should be sown as early in April as possible, when soil temperature reaches 8°C, into light, free-draining soils in South-facing fields that warm up quickly during the spring and drain well right through until harvest. Whereas crops grown for crimped maize production typically require a seed rate of 38,000-40,000 seeds/acre, for grain maize production this should be reduced to 36,000-38,000 seeds/acre.

“In addition to its many economic benefits, grain maize also has significant environmental benefits. The defra guidelines indicate that farmers should sow a green cover crop after harvesting forage maize to prevent soil erosion. With grain maize, however, this is not necessary as the stova is chopped and spread, creating a ‘mat’ that allows machinery to travel on the land more easily, greatly reducing soil erosion/run-off, improving soil structure and lowering the export of Phosphate and Potash from the field/farm, a big win-win situation given the current rising cost of fertiliser”.
