What sort of brassica are you after?

  • Cleancrop brassica – The HT Brassica system has a range of cultivars that have been BRED to be tolerant to the sulphonyl urea herbicide Telar, a broad-spectrum herbicide that provides excellent control of broad leaf weeds from the pre-emerge.
  • Kale – Kale (also known as Chou Moellier) is winter active and mainly used as a “winter feed”.
  • Rape – Forage rape may be sown alone or in mixtures as a specialist “summer to winter feed”.
  • Forage brassica – Forage brassica (also known as Leafy Turnip) may be sown alone or in mixtures as a specialist “summer to winter feed”.
  • Turnips – Turnips can either be spring (for summer feed), summer or autumn(for autumn or winter feed) sown.
  • Swedes – Swedes are sown between November to early December, either ridged in cool areas, or conventionally drilled to provide specialist winter feed.
  • Fodder Beet – Fodder Beet is one of the highest yielding forage options available to farmers, but it is actually not a brassica!


 

Cleancrop brassica:

The Cleancrop Brassica system is a simple weed management system which eradicates a range of key problem weeds commonly found in brassica crops.

Weed control is applied at the pre-emerge stage within 48 hours of sowing.
Weeds controlled include the following:

  • Calandrina, Californian Thistle, Chickweed, Cornbind, Dandelions, Docks, Fathen, Hawksbeard, Nodding Thistles, Rayless Chamomile, Redroot, Scarlet Pimpernel, Scentless Chamomile, Scotch Thistle, Shepards Purse, Spurrey (Yarr), Stinking Mayweed, Twin Cress, Vetch, White clover, Wild Turnip*, Willow Weed, Yellow Cromwell.

* Apply Telar pest emerge when Cleancrop brassica are at the forth-true leaf stage. Consult your retailer to order 2nd Telar spray.

Kale:

(Sowing rates: 4 – 5 kgs per hectare)

Kale can provide high dry matter/ hectare yields however for best results kale requires high soil fertility and good soil moisture. Kale is suitable for cattle, sheep, and deer but the taller or giant types are best used for only cattle grazing, while the shorter, leafier cultivars are more suited to sheep and deer. Higher sowing rates lead to thinner and more palatable stems.

There are three types of Kale:

  • Medium Stem types: Lowest growing of the three Kale types medium stem kales normally have high leaf to stem ratios which makes utilisation better but have the lowest yield potential of the three types. Also medium stem types have improved lodging resistance which make them excellent in snow prone areas. Suitable for all stock types but normally used for sheep grazing
  • Intermediate Stem types: These types are the result of crossing a medium stem and giant stem type together to get the most desirable traits from each parent. Higher and narrower stems intermediate kales have very good leaf to stem ratios leading to higher palatability and utilisation. Suitable for all stock types
  • Giant Stem types: Giant stem types obtain more of their yield from their stems rather than from their leafs. In the man these kales are only used for cattle/dairy cow grazing where a high overall yield per hectare is required. Grazing management is very important otherwise they can have poorer quality than the other two types

Rape:

(Sowing rates: 0.5 – 1 kgs per hectare)

Rape can be sown from early spring to late summer and is generally ready to graze 12-16 weeks after sowing. Rape can be sown on lower soil fertility soil than most other brassicas. With good soil fertility and moisture, yields of 8 tonne DM/ha can be achieved. (Note: Some care is required when grazing rape and it is best to allow the crop to fully mature before grazing and to gradually increase Rape in their diet.)

Forage brassicas can be sown from early spring to late summer and have minimal maturity requirements before grazing. Forage brassica can be sown on lower soil fertility soils than most other brassicas. With good soil fertility and moisture, yields of 10-12 tonne DM/ha can be achieved. (Note: Some care is required when grazing stock on Forage brassica and it is best to gradually increase it into their diet.)

Turnips:

(Sowing rates: 0.5 – 2kg per ha)

Turnips vary in yield potential, ploidy level, maturity, size of bulb, bulb keeping quality, and these factors considerably influence the choice and intended mixtures with rape or grasses, particularly Italian Ryegrasses. Yields tend to increase with later maturity types and vary from 5 to 8 tonne DM/ha. Turnips being Root Crops provide greater resistance to aphid than rape crops but are more senstitive to deficiencies of boron, particularly in wetter areas. Stock grazing root crops need sound teeth to make effective use of them, and energy requirements are higher because of high water content of the bulbs.

Swedes:

(Sowing rates: Alone: 3 -4 kg. Mix: 0.5 – 1kg per ha)

Turnips can yield between 10 to 16 tonne DM/ha over the winter months. Swedes being Root Crops provide greater resistance to aphid than rape crops but are more sensitive to deficiencies of boron, particularly in wetter areas. Generally yellow fleshed swede varieties are commonly used for human consumption because of improved flavour and lower water content compared to white fleshed type. Stock grazing root crops need sound teeth to make effective use of them, and energy requirements are higher because of high water content of the bulbs.
