HUSBANDRY GUIDELINES
ROTATION
Excellent first, second and continuous wheat.
DRILLING RATE
The optimum drilling date for Deben is the end of September through to early October. Deben can be safely drilled until mid February.
SEED RATE
In order to decrease lodging risk, care should be taken with seed rates. Seed rates should be similar to Claire when drilled at the end of September i.e. 200-265 seeds per sq. metre. This assumes good seedbed conditions with moisture available. The earlier the sowing date, the lower the seed rate that should be used. Deben has large seed with a high thousand grain weight. Care must be taken to ensure the crop is not drilled at too high a seed rate.
NITROGEN
The exact amount will depend on soil type, yield potential and residual fertility. In first wheats, early applications of nitrogen should be avoided. In most instances, two thirds should be applied at the terminal spikelet stage and the remainder approximately 4 weeks later.
DISEASE CONTROL
Deben has excellent disease resistance so there are opportunities to reduce fungicide usage particularly when targeting Septoria and yellow rust. Resistance to mildew is moderate so attention should be paid to controlling this disease if infection occurs.
GROWTH REGULATION
Deben is highly responsive to plant growth regulators. Careful timing of chlormequat(CCC) based products is important to reduce the threat of lodging.
HARVEST
In order to take full advantage of Deben’s good grain characteristics, priority should be given at harvest over feed varieties.
