Tim Lamyman is constantly rising wheat crops yielding 15t/haps utilizing a high-input, high-output system throughout quite a lot of varieties on his Lincolnshire Wolds farm.
His methodology of utilizing excessive ranges of nitrogen, micronutrients and fungicides has produced prime yields of wheat varieties corresponding to Theodore, Champion, Colosseum and Garibaldi.
In a season when foliar illness arrived late in Mr Lamyman’s wheat fields, fungicides have been key in his three-pronged method.
“For those who drop one in all these parts – nitrogen, crop vitamin or fungicides – crops will undergo. This season, crops definitely wanted the fungicide aspect and plenty of who in the reduction of on fungicides noticed flag leaves misplaced early,” he says.

Lack of daylight
This was not a basic high-yielding season, with daylight down 20% within the spring and summer time, however Mr Lamyman nonetheless grew some large crops on his 600ha largely arable farm at Worlaby, simply south of Louth.
He grows 4 key varieties as first wheats in an intensive system, utilizing 350kg/ha of nitrogen, a five-spray fungicide technique and micronutrient programme.
The nitrogen is utilized in 4 splits and the fungicide programme features a T4 to guard towards late brown rust. Two micronutrient foliar feeds are utilized within the autumn to assist rooting, and 5 within the spring, together with fungicides to help with development and improvement.
This high-input, high-output methods price about £250/ha greater than his commonplace farm method, which requires 220kg/ha of nitrogen and less-intensive programmes of fungicides and micronutrients.
The intensive method has seen him take the highest yield title within the Yield Enhancement Community (YEN) competitors, organised by crop marketing consultant Adas, for 5 out of the eight years it has been run. He additionally holds the present winter barley yield world file, and he has been the world file holder for wheat and oilseed rape yields up to now.
As a part of his drive for consistency and seek for wheat varieties to suit right into a second, third and fourth cereal spot, he has assessed quite a lot of varieties and highlights 4 from this season.
This feed wheat with wonderful septoria resistance is a shy tillering selection, so requires a excessive seed charge and selective drilling window.
Mr Lamyman grew 13ha of this DSV-bred selection for harvest 2021, and it gave a yield of 15t/ha with a particular weight of 74.5kg/hl. The crop was drilled on 30 September at a comparatively excessive seed charge of 250kg/ha.
He says this was one of many best wheat varieties to handle due to its good illness resistance, particularly to septoria. It additionally doesn’t appear to undergo too badly from drought within the spring.
“Due to its good illness resistance, we felt we may push the yield on the suitable sort of land. I believe it’s a selection that could be proper for the early drilling slot,” he says.
The crop was harvested on 18 August, giving an ear inhabitants of 770 heads/sq m.
The variability has the benefit of excellent standing energy, early maturity and a great illness resistance package deal, but it surely have to be drilled between 25 September and the final week of October, he says.
He’s on the lookout for a second wheat to interchange his previous favorite, Marston, so Theodore appears to be like like a great, stable wager, and he plans to extend his space as much as 50ha this autumn.
That is one other feed wheat selection from DSV with nice yield potential, which yielded 14.9t/ha this summer time, regardless of utilizing a a lot decrease seed charge due to the scarcity of obtainable seed.
The variability, which was picked out by Mr Lamyman’s son, Rob, threw up plenty of grains per ear, and has superb septoria resistance for a Group four feed wheat.
“We imagine the variability has the potential to be pushed onerous with the suitable daylight and water, however this season we have been in need of daylight,” he says.
The variability was sown on 13 September at 75kg/ha, giving solely 81 crops/sq m, however produced practically 15t/ha, with a great particular weight of 76kg/hl.
Every massive wheat ear delivered 65-70 grains, and was harvested on the identical day as Theodore.
Mr Lamyman says this tall selection has a really extensive drilling window, from mid-September to the top of December, though he warns towards ultra-early drilling because of its straw peak.
“We expect it exhibits good grain high quality and seed measurement, and it appear like a really constant selection, with an extremely extensive drilling window.”
He plans to extend his space of the variability from 9ha to 40ha this autumn, as he feels the variability has large potential on the proper seed charge. This autumn he’ll use a better seed charge of 125kg/ha.
He’ll assess whether or not Champion or Theodore can take over the second wheat place from Marston, which is essentially the most constant wheat he has ever grown and produced yields of 9.5-13.9t/ha within the second, third and fourth wheat slot at harvest 2021.
This feed selection from breeder KWS is one other early driller like Theodore. It produced 15.6t/ha, however at a disappointingly low particular weight of 71.5kg/hl.
It delivered a daring pattern, however with out the hoped-for first rate particular weight. If the particular weight had been 78kg/hl, this might have challenged the New Zealand-held wheat world file of 17.4t/ha, set in February 2020.
The variability was drilled on 14 September at a seed charge of 225kg/hl because of its shy tillering. It may fill the early drilling slot, as it’s a gradual to medium starter at rising away.
It once more produced large heads of 55-60 grains/ear and had a comparatively small flag leaf, which permits gentle to get to leaves two and three.
“It’s the most constant of the early-drillers, and has good standing energy and usually good illness resistance,” Mr Lamyman says.
It does have barely low resistance to eyespot, so he included the azole prochloraz at T0 and prothioconazole at T1.
This wheat selection from impartial breeder Invoice Angus is an extremely robust tillerer, so is properly suited to late drilling.
It produced a yield of 14.7t/ha this summer time at a great particular weight of 78kg/hl after being drilled on 30 September at a seed charge of 200kg/ha.
A second discipline drilled later in November yielded 12.9t/ha at 79kg/hl. It exhibits related tillering means to Champion, throwing up daring heads.
“I see this selection as a implausible late-driller with an unbelievable tillering functionality, giving good grain measurement and an excellent crop,” he says.
This season, Mr Lamyman will probably be rising one other 20ha of the variability, making an attempt it out as a second wheat drilled from late October to the primary two weeks of November at a comparatively low seed charge of 150kg/ha.
This tall selection may show a really helpful late-driller from mid-October to end-December, and could possibly be good in a delayed-drilling state of affairs to manage blackgrass.
The one new selection Mr Lamyman is making an attempt this season is Hurricane, from breeder Limagrain, which has a great tillering means.
