Therefore, a fine, firm seedbed should be produced and rolled after sowing. Sow in February to May, when soil temperatures have reached around 8°C. Nutrition Check indices and apply P&K to seedbed if necessary. A well-established crop will need a nitrogen target of 75-150kg N/ha. This can be achieved in one application after establishment and under good growing conditions to avoid leaching losses. For the best result, apply in 2 or 3 applications. Ideally the first application should be a DAP or compound NPK for improved N up-take*. Sulphur and nitrogen should be applied before the start of stem extension. Consider applying micro-nutrients depending on soil pH. If it is high or low then micro-nutrients may be locked up. Plant Growth Regulators are not required. * Apply according to RB209 guidance Pests Flea beetle attack on cotyledons can be a major problem, crops must be monitored as often as possible during emergence, using the trap method. Be prepared to spray for flea beetle several times during the establishment stages. Pigeons are not so much of a problem as in winter oilseed rape because spring varieties are vigorous once established. However, if cold and wet weather conditions occurs at early growth stage (1 -6 leaves), then they may become a problem as the crop stops growing. Pollen beetle can be a problem in spring rape and must be monitored.

Doktrin Spring Oilseed Rape Lumen Hybrid Spring Oilseed Rape Makro Hybrid Spring Oilseed Rape ^CMirakel Spring Oilseed Rape Diseases Fungal diseases occur less than in winter oilseed rape and spraying may not be economically justified. Alternaria can occur to damaging levels if conditions are favourable (warm and humid weather during flowering and maturation). With a hybrid variety like Doktrin, one application of a triazole is suggested for Sclerotinia. Weeds Broad-leaved weeds Weed control is by application of pre-emergence chemical(s) BASF Butisan® or Katamaran®. If good growing conditions...
