Why sow forage rape?


Spring-sown rape fills the summer feed gap. The perfect non-pasture feed for stock when facial eczema spore count or internal parasite larval challenge is high. Finish lambs, feed your ewe lamb replacements or flush ewes late summer. For milking platforms, plant rape as part of your summer brassica feed system, start by grazing Barkant® summer turnip and switch to forage rape in late summer. This means cows spend more time on summer brassicas. Autumn-sown rape delivers high quality winter feed just when you need it.


Forage rape is a high quality feed with nutritional benefits for grazing animals. The excellent leaf percentage of rape (average 68% leaf) and soft stems mean better performance by stock. Rape contains energy levels of 11-13 megajoules of metabolisable energy (MJME)/kgDM and moderate to high crude protein content (Westwood and Mulcock 2012*). The ideal high quality forage to balance summer pastures or silage/straw supplements over winter.


Single or multi-graze, the choice is yours. Goliath® and Titan® are new generation, multi-graze cultivars that are an interspecies cross between rape and kale parentage. Graze now, close up for a month and regraze later. Expect up to 3.5 tDM/ha regrowth at the first regrazing. Combining Goliath or Titan rape with an Italian or short-rotation ryegrass increases the flexibility of rape as a multi-graze option.


PGG Wrightson Seeds rape cultivars range in maturity dates from 70-110 days after sowing (DAS). Ideal for matching feed supply with stock demand and avoiding crops being ready to graze at the wrong times. Planting two forage rape cultivars on the same day allows you to leverage the variation in plant maturity to graze feed over a longer period. Graze early maturing Titan 70-90 DAS. Later maturing Goliath and Cleancrop™ rape are ready to go 90-110 DAS.


Compared with other brassica species, forage rape tolerates lower soil fertility – a suitable option when soil tests come back with less than ideal results. Like all species, forage rape dry matter yields improve when soil fertility is optimal. For areas prone to summer or autumn dry, choose forage rape. Rape is more tolerant of drier growing conditions than other summer brassicas such as leafy turnip and bulb turnip. Despite tolerance of dry conditions, rape performs best when irrigated or planted in summer-safe areas.

Cleancrop™ Rape

Cleancrop™ rape is a high yielding, multi-graze forage rape with good leaf percentage and excellent crop ultilisation by animals. As part of the Cleancrop Brassica System, it has the added benefit of a herbicide resistance trait. Telar® herbicide can be applied at both pre- and post-emergence for excellent weed control, freeing up moisture and nutrients to give this multi-purpose forage rape the best chance of maximising summer, autumn and winter feed.

  • High yielding, multi-graze rape with good leaf percentage and crop utilisation
  • Multi-purpose forage rape with excellent summer/autumn/ early winter feed
  • Good regrowth potential with excellent winter keeping ability
  • Similar Aphid tolerance as Goliath®
  • A new generation rape and kale interspecies cross
