Fodder Radish


(Raphanus sativus)

Also commonly known as oil radish, fodder radish is a brassica, it is not a legume but it will hold any residual nitrogen in the soil, which it will then release as it breaks down over time. This species is slower to flower and go to seed than mustard and produces a deeper root system.


Used for increasing organic matter and breaking through layers of compaction in the soil. Also used as a seed bearing component of wild bird mixtures.


Fodder radish is an annual brassica.


Fodder radish holds residual nitrogen in the soil, which it will then release as it breaks down over time It produces a large amount of biomass, which can be incorporated into the soil. This quick growing species is competitive against weeds forming early ground cover in a basal rosette before gaining height and producing a flower head after 6-8 weeks.

Frost Tolerance

Fodder radish is more tolerant to lower temperatures than mustard, however it is not frost hardy and several sharp frosts will usually kill off the plant.


Large amount of biomass can be produced and incorporated into the soil.

Sowing Rate Advice

5kg per acre / 12.5kg per ha.

This small brassica seed should be broadcast or shallow sown on to a fine seedbed. It should be rolled immediately after sowing. The sowing rate is variable if covering large areas.

Mixture Sowing Rate Advice

Vegetative State

Flowering Plant

Flowering Plant
As with most brassicas, fodder radish grows from a basal rosette, but with a glossier leaf surface than some. It develops rounded, segmented, toothed to lobed leaves, that almost cut back into the midrib. It can be slightly sprawling in its growth habit, but with a stout centre stem. The flowers are generally white but can be pinkish to lilac, or have coloured veins. Later developing obvious seed pods. It has a stout taproot with several lateral side shoots.

Additional Info

Itís a similar plant to mustard but typically flowering later than mustard and taking longer to set seed.

Works well with

It can provide a deeper root structure to break up soil compaction when combined with the shallow rooting mustard. It can also be combined with seed bearing species like gold of pleasure, mustard, or millets for winter bird food.
