The main thing of the cultivation decision is primarily the variety and its suitability for the location. However the sowing date and sowing density are also definite, irreversible factors for the new rape crop.

While the sowing window is around 4 weeks, the harvesting window is much narrower. As a rule the difference in ripening between an early maturing and a late variety is approximately one week. Especially on large farms, it is worthwhile taking the variety- specific maturity differences into consideration when organising the combine harvest operation.
