Fungicide use
Always consult your agronomist and adapt programmes to local conditions.
Many winter wheat varieties face an added threat from a new yellow rust race this season. Whilst Duxford is less susceptible to this new race than some varieties due to its parentage, this threat must still be taken into account along with Septoria tritici and brown rust. Use of a T0 fungicide has taken on increased importance.
- T0 - Cherokee 0.75-1.0lt/ha
- T1 - Cherokee 1.75 lt/ha (Unix 0.5 kg/ha if high risk of mildew / eyespot)
- T2 - Amistar Opti 1.0 lt/ha + Opus 0.75 lt/ha
- T3 - Amistar 0.3 lt/ha + Proline 0.3 lt/ha
Agronomic information
Duxford has the maximum 9 rating for resistance to lodging (with and without a PGR).

Growth habit
- Duxford is a medium to high-tillering variety
- Duxford is a fast developing variety
- Suitable for drilling mid-September onwards for England and the end of September for northern England and Scotland
Recommended sowing rates
Seed rates are dependent on soil conditions, rotation and time of drilling. The more difficult the environment, the higher the seed rate needs to be to compensate for potential plant loss. Suggested seeds per square metre are shown below, these should always be used in conjunction with TGW.
- Mid-September to mid-October: 220-275 seeds/m2
- Mid-October onwards: 275-300 seeds/m2
Nitrogen application
Standard nitrogen input programme for a feed variety, typically not exceeding 180 kgs N/ha.
- 40% middle of March (GS25-29)
- 60% April (GS32)
These figures are for guidance purposes only. Although Duxford is a Group 4 variety it does have gristing potential, therefore N should be increased appropriately if growing for quality (for example, an extra 40-60 kg/ha at GS37-39). You must work with your agronomist when calculating nitrogen rates and timings, taking into consideration end market requirements and the fertility of the field. You should also work within any Defra guidelines / restrictions.
PGRs
- Duxford is a very stiff-strawed variety with excellent resistance to lodging
- In low plant populations, Moddus applied at GS29-30 will help root stimulation and promote tiller numbers
- As an insurance measure apply chlormequat 1.25lt/ha + Moddus 0.1 lt/ha at GS30-31
Grain quality
Duxford has excellent grain quality.
- Specific weight ~ 75.7kg/hl

Duxford also has gristing potential and, when grown for quality, can meet full milling specification (nitrogen input would need to be adjusted to ensure protein levels). Always check the exact specifications required by end users to ensure that you have a market for your crop.

Storage management
nabim advises that Duxford tends to have strong gluten quality, so check with your merchant to see if it is worthwhile keeping Duxford separate in store. Detailed wheat storage and marketing information can be found in the nabim publication ‘Getting it right’ and on the nabim website: www.nabim.org.uk
