Oilseed Rape in the Dry: Exactly how much rain do we need?

Will oilseed rape establish this autumn? With many growers still waiting for meaningful rainfall after a prolonged dry summer, drilling decisions are becoming increasingly difficult. In this article, we explore why soil moisture matters more than drilling date, how much rain may be needed to trigger successful establishment, and what realistic growth targets look like if drilling is delayed. We also cover variety choice, seedbed preparation, fertiliser placement in dry conditions, and the practical considerations that could influence establishment success this autumn.
