Turnip rape is genetically different to oilseed rape and grows quickly in the autumn with excellent nitrogen catching and very high organic matter production.
Fast growing varieties can be sown late in September to early October. It needs care in an oilseed rape rotation but can be good value with a low sowing rate.
Winter turnip rape is late to flower so can be sown earlier than oil radish if needed. It can be useful in a mixture with oat species.
