Agronomic information
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. Ketchum performs very well in the late-drill slot.
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: 250-300 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 180-240 kg/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.
