High yielding breadmaking winter wheat
Yield potential
Ketchum is a very high yielding nabim Group 2 winter wheat, with an unbeatable second wheat yield among breadmaking varieties. Ketchum also has the highest yield of all breadmaking varieties in a late-drilled situation (over 0.5 t/ha more than Xi19).

Fungicide use
Always consult your agronomist and adapt programmes to local conditions.
Core fungicide programme
With all high yielding varieties, a robust fungicide programme is likely to result in an increase in yield. As with other varieties, with a new race of yellow rust now present, it will be important to factor this into fungicide decisions from the start.
- T0 - Cherokee 0.75 lt/ha only if rust risk is high
- T1 - Cherokee 1.5 lt/ha + Unix 0.5 kg/ha
- T2 - Amistar Opti 1.25 lt/ha + triazole (60% rate)
- T3 - Amistar 0.5 lt/ha + triazole (quarter to half rate)

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 the end of September onwards.
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 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
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 180-240kg/ha
- To increase the grain protein level, 40-60 kg of the total N should be applied at flag leaf fully emerged (GS39)
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 0.2 lt/ha + chlormequat 1.25 lt/ha at T1
- Apply an ethephon-based product at T2
Grain quality
Ketchum is a nabim Group 2 variety and, when grown for quality, meets the specifications required for breadmaking.
