Chamaecytisus palmensis

Scientific name

Chamaecytisus palmensis

Common name

Tagasaste

Tree lucerne

Origin

The plant appears to have originated from the Canary Islands, but is found in most countries with a Mediterranean climate (Snook, 1982). It is also common in new Zealand and has been introduced to parts of Africa (Anonymous, 2000)

Botany

Chamaecytisus palmensis belongs to the Fabaceae family. It is a evergreen bushy tree with profusing white flowers and form flat black pods about 5 cm long, each pod containing about 10 seeds. The seeds are flat, oval and about 5 mm long by 3 mm wide by 1 mm thick. 1 kg contains about 45.000 seeds (Dann and Trimmer, 1986). If grown alone can Chamaecytisus palmensis reaches an hight of 7 – 8 m, but normally it grows multistemmed and spreading of which it reaches a hight of 5 – 7 m (Anonymous, 2000).

Ecology

Chamaecytisus palmensis grows well in a range of enviroments and once established handles climates ranging well. It has been grown mainly in temperate regions with wet winters and dry summers, with annual rainfall ranging from 350 to 1600 mm. It is has been reported that Chamaecytisus palmensis is moderate frost tolerant (Milhorpe and Dann, 1991). However, there has also been reported, that in New South Wales in Australia due seedlings proliferate vigorously along roadside despite annual frost to – 15 ░C (Anonymous, 2000). Once Chamaecytisus palmensis is established is it resiliant to drought (Milhorpe and Dann, 1991). Anonymous (2000) reported that ‘seedlings are remarkably drought resistant and can survive six months of hotweather without rain or irrigation. Of more importance, established shrubs have a remarkable capacity to recover from defoliation. Regrowth occurs even in the prolonged absence of rain’. On the side there has been reported that Chamaecytisus palmensis is very sensitive to water logging (Dann and Trimmer, 1986).

It can be established on a wide range of soils types (gravels, loams, acid laterites and limestones), but is established best on sandy-surfaced soils and has been very useful for the reclamamtion of eroded soils (Dann and Trimmer, 1986; Anonymous, 2000). It can cope with at least moderately acid soils with a pH of 5.0 to 7.0, but requires soils that are free draining (Dann and Trimmer, 1986; Anonymous, 2000).

Pest and Diseases

No major attack have been describes (Snook, 1982). However, if there are waterlogged conditions, even for a short period has there been reported to arise problems with the root disease Fusarium oxycarpum (Dann and Trimmer, 1986). If bark from Chamaecytisus palmensis has been stripped of by browsing sheep has there been observed that many plants died of Phytophthora fungus (Dann and Trimmer, 1986).

Establishment

Chamaecytisus palmensis can be established by drirect seeding or transplanting. The hard coat of tagasaste seed results in a very low gerination of untreated seed. The seeds have therefore be treated by scarifying or hot water treatment. The seed is is dropped into the hot boiling water and the container removed from the heat right away, where the seeds is left to soak. Swolen seeds can be sieved out, while those who are not are treated again (Dann and Trimmer, 1986). If the soil in which Chamaecytisus palmensis is planted does not contain rhizobia bacteria for the nodulation of the plant has the plant to be inoculated with appropiate rhizobia. This can be done by taking soil from around the roots of a healthy mature Chamaecytisus palmensis tree (Dann and Trimmer, 1986).

Although, Chamaecytisus grows rapidly, weed competition can be a problem, as well as young tree should be protected well for animals, since it is very palatable. Furthermore, does is it not tolerante to waterlogged conditions during the establishement, eventhough it is just for a short time (Milthorpe and Dann, 1991).

Yield

With spacing of 4 plants/m of over 4.5 kg/m of hedge were achieved in the third and fourth years after establishment from which 66% was ‘edible’ (McGowan and Mathews, 1992). Anonymous (2000) reported that ‘under current systems of dryland farming in Western Australia, plantations should produce at least 10 t/ha of edible dry matter from a single annual grazing or cutting. This is equivalent to 1.5 kg each for 18 sheep every day of the year. If plantations are harvested three or four times a year, or subjected to rotational or continuos grazing, yields can be even higher’.

Major uses and functions

Chamaecytisus palmensis is mainly used as forage, firewood, improving soil fertility through nitrogen fixation, against wind and water erosion and as a source of nectar for bees (Mengistu, 1997; Springwood, 1996).

Fedding value

Chamaecytisus palmensis has a high palatability and is normally readily consumed. In vitro dry matter digestibility of the leaves has been found to be high: 0.77 – 0.82 (Borens and Poppi, 1986) and 0.72 (McGowan and Mathews, 1992). It has a high feeding value, since the content of secondary plant compounds is generally low. Most elements have been found to be adequate in leaves, except from P which can be marginal and Na, which is low. It has therefore been suggested to offer a complete mineral mix to animals grazing Chamaecytisus palmensis (Borens and Poppi, 1990).

In an experiment of Varikko and Khalili (1993) cows were fed a basal diet of ad libitum native hay and replacing 4.5 kg a concentrate mix, which was based on noug (Guizotia abyssinica) cake and wheat middlings with Chamaecytisus palmensis on a weight-for-weight basis of 0, 33, 66 and 100 %. The cows refused to eat the higher levels of 66 and 100 %, which resulted in a significant (p<0.001) lower total dry matter intake crude protein intake. The decline in nutrient intake resulted in an decreased milk yield from 5.18 kg day-1 (100% concentrate mix) to 4.02 (100% Chamaecytisus palmensis), as well as the protein content content in the milk decreased.
