Download a copy of the Interval Rape factsheet.
Interval rape is an exciting variety that has a lot to offer. Interval is coated with the AgriCOTE ProTech coat giving up to 4 weeks protection against insect attack. It is also extremely vigorous, fast establishing giving it a better chance to survive insect attacks or environmental stresses during early growth. Grazing can start as early as 8 weeks after sowing depending on the start to the season. Interval rape has shown a very good leaf to stem ration compared to other varieties on the market (see photo below) crops of Interval Rape have measured 19% CP (crude protein) and 13.4% MJ/MEkg DM (energy).
Excellent regrowth after grazing can be obtained through good management practices ie back fencing with an electric fence. Early indications are that you can expect up to 4 ton of dry matter at the first grazing and with re-growth you could expect to gain an extra 2 ton of dry matter for the season. The added advantage is that you can let Interval Rape grow into the winter months if that suits your rotation and by adding some Hulk Italian ryegrass as an over ow you can take the paddock through for a silage or hay crop as well as obtaining good grazings along the way.
Ideally drill the seed into a firm and moist seed bed at 1-2cm depthRecommended sowing rates of 4-5 kg/haApply sufficient starter fertiliser, such as DAP/MAP at 100 kg/ha.
Monitor early for evidence of pests, such as Slugs, RLEM, Lucerne Flea and CutwormOnce at ground cover consider a topdressing application of Nitrogen, as UreaCheck for leaf chewing pests, such as Diamond Back Moth, and treat as required.
Interval is a rape-kale cross, giving high yield with good re-growth ability.
Flexible sowing date:
Interval can be sown from spring through to early autumn to provide a bulk of high quality feed in around 56-84 days. Late spring sowings can be grazed in summer/early autumn then left to re-grow for winter feed.
Interval has performed well in trials – providing excellent DM yields.
Excellent winter utilisation:
Compared to kale, rape typically has higher feed quality, and is better utilised by stock.
Interval has excellent tolerance of dry conditions. It also has strong frost tolerance and resistance to powdery mildew.
