Grain quality
Ketchum is a nabim Group 2 variety and, when grown for quality, meets the specifications required for breadmaking.
Source: HGCA Recommended List 2009-10. On the 1-9 scale high figures indicate that a variety shows the character to a high degree (e.g. high resistance).
Growth habit
Ketchum has a semi-erect growth habit and will benefit from the application of a PGR. It has rapid growth through stem elongation and is suitable for drilling from October onwards.

Agronomics
Always consult your agronomist and adapt to local conditions.
Seed rate
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 seed rates per square metre are shown below, these should always be used in conjunction with TGW.
- Early October: 220-250 seeds/m2
- Mid-October onwards: 250-275 seeds/m2
Core fungicide programme
As with all high yielding varieties, a robust fungicide programme is likely to result in an increase in yield.
- T0 - Cherokee 0.75lt/ha only if disease risk is high + triazole if rust risk is high
- T1 - Cherokee 1.25-1.5lt/ha + Unix 0.5kg/ha
- T2 - Amistar Opti 1.25lt/ha + triazole (60% rate)
- T3 - Amistar 0.5lt/ha + triazole (quarter to half rate)
Nitrogen application
Ketchum’s high yield means that extra nitrogen may be required to ensure that breadmaking specifications are met.
- Total application in the region of 180-220kg/ha
- 40-60kg N/ha at flag leaf fully emerged will increase the grain protein level
These figures are for guidance purposes only. 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
- Ketchum is a tall-strawed variety with moderate standing power
- Apply Moddus 0.2lt/ha + chlormequat 1.25lt/ha at T1
- Apply an ethephon-based product at T2
Storage management
Correct storage of quality wheat is a priority to ensure harvest quality remains. 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
