Rapid growing ability with good winter hardiness. Forage rape is a high-energy feed for grazing ruminants.
- Sowing rate: 4-5 kg/ha (if broadcasting use a higher rate)
- Frost tolerance: Good

- Pests & diseases: Generally not a problem, but clubroot could become an issue if brassicas are used as a cover crop over a period of years.

Sowing time: July to late August

Sowing instructions: Soil test approximately eight weeks prior to sowing. Cultivate to achieve a fine, firm seedbed. Ploughing will help level rough fields. Apply lime as per soil test results. Sow in good conditions (warm with rain forecast), no deeper than 10 mm. Roll well after sowing to ensure good soil/seed contact. Apply N, P & K as per soil test results and nitrates rules.
After sowing: Monitor for pest attack and seek advice where a problem arises

- Brassicas are low in iodine, copper, cobalt and selenium – a slow-release bolus will ensure animals receive adequate minerals
- Supplementary fibre (e.g. silage, hay or straw) should account for 30% of the diet, with 70% coming from the brassica
- Introduce stock to brassicas gradually (build from 1-2 hours access per day to full-time access over 10-14 days)
- Always ensure animals have access to fresh water
