Description

Oil radish or melioration radish is a variety, rarely a subspecies of garden radish, which belongs to the cruciferous family (Brassicaceae). Oil radish grows rapidly (up to 1 m tall), produces strong leaf growth in a short time, and forms deep (up to 1.5 m) taproots. Its seeds are very oleaginous. Susceptibility to cabbage hernia is not as severe as in other cabbage crops. Heavy shading of the soil is to be expected even at the young plant stage. Not hardy. Now grown for green manure rather than oil. Insect friendly.

Growing tips

Can be used as a green manure, soil loosening, nematode control and weed suppression. Good soil cover. Seeds germinate already at 2-3°C. For seed collection sowing from March to May. For green manuring until mid-September. Broad-cast or in rows. Approx. 3 g per m^2. Germination at above 2°C after 2 weeks. Drought resistant once taproot has formed. If sown early, cut off flowers to avoid self-seeding. Used as a rotation crop of sugar beets.
