Fodder radish May 17, 2016
Fodder radish has a rapid initial development and can provide high dry matter yields, especially with an ample supply of nitrogen. The crop tolerates the first night frosts well, allowing it to have quite a long period of growth.
Fodder radish can be sown both in spring and autumn. The spring planting is aimed at combating the beet cyst nematode. When the crop is three-quarters in bloom, it must be mown at 25-30 cm height. The plants will then sprout again.
Fodder radish is one of the few cruciferae which is not susceptible to clubroot. The crop can therefore be cultivated without any problem in crop rotation with cabbage. However, the cabbage moth can multiply in fodder radish. The fodder radish itself does not sustain any damage from this.
Some fodder radish varieties possess a resistance to Alternaria. It concerns Alternaria species that also occur in other cruciferae such as cabbage and rapeseed. Fodder radish has no effect on Alternaria species that affect, for example, carrots and potatoes.
Since 2009, varieties with resistance to Meloidogyne chitwoodi have been available. Some varieties are double resistant (M. chitwoodi and beet cyst nematodes).
