BARENBRUG STYLO SIRAN COATED PER KG 171227

Shrubby stylo is native to South America in Northwest Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Venezuela and also in the Caribbean in the Bahamas & Cuba. Siran is a more leafier variety than Seca, and is a composite of 3 bred or selected lines (‘Jecuipe’, ‘Recife’, ‘Feira’) to provide multiple-gene resistance to anthracnose.

Siran is adapted to a wider variety of conditions when compared to Seca, and produces a large quantity of highly nutritious feed for the dry season.

Used in perennial pasture, in grassland or open woodland. Although sometimes sown with introduced grasses, it is most commonly sown into native grassland.

Used for cut-and-carry in some countries. Young regrowth has qualities that suggest value for fodder conservation. Agro forestry potential, providing shade not too intense.

Well adapted to infertile, acid, friable or hard-setting, sandy-surfaced soil; not as well adapted to heavier textured, less acid soils, and not suited at all to heavy clays.

A shrubby legume, that can grow up to 2m tall.

Under heavy grazing, plants can adopt a low, almost prostrate growth habit, to 5 to 10cm high.
Siran has a large tap root to 4 m deep.

Features:

An erect shrubby perennial that can grow up to 2m tall
Exhibits greater Anthracnose tolerance than Seca
Widely adapted and can persist under heavy grazing

Recommended planting rates for AgriCOTE Siran Stylo are:

2 - 5Kg per Hectare Since seedlings are slow to develop, it is best to sow at the end of the dry season or early in the wet season to allow plants to develop sufficiently before the next dry season or the onset of frost.
Siran can be sown conventionally into the soil, or by air. In tropical Northern parts of Australia, Siran Stylo is also commonly included in “loose lick” fed during the dry season, and readily establishes in the dung.

Variety Management / Agronomy:

While seedlings are very slow growing for the first season, they are particularly hardy and able to establish unless grass competition is strong.
In the establishment year, grazing pressure should be managed to minimise grass competition, but the stand should not be heavily grazed once plants start to flower, to encourage seed-set and stand thickening.
In subsequent years, it is best to avoid heavy grazing in the early part of the season, since stock select the grass leading to grass decline and stylo dominance.
This can lead to weedy pastures and soil acidification. However, it may be advantageous to graze heavily following burning and oversowing to reduce competition for the developing seedlings from established perennial grasses.

Performance:

Dry-matter yields on poor soils in a low rainfall area may be less than 1 t/ha, but up to 10 t/ha under more ideal conditions.
In grass/legume pastures it can contribute 2-7 t/ha DM.

Animal Production:

Annual liveweight gains of 140-160 kg/hd can be achieved from grass/legume pastures.
Nutritive value declines with age, leaf crude protein from 20 to 10%, P from 0.3 to 0.1% and IVDMD from 70 to 50%. ADF values of about 30 % in the leaf, and 43% in the stem of the terminal 15 cm of shoots have been measured. Proportion of stem increases with age, from about 20% early in the growing season to 75% at the end of the season (and higher in grazed pastures).
This varies considerably with ecotype.
Often need supplementary P to achieve best animal performance.
Na levels are much higher than those for many other tropical legumes and may be 1-2 % of DM in leaf and stem.
