There are around 10.500 vascular plant species in the Flora o f Turkey (I, 2). Some o f these

species are used for different purposes such as medical, nutritious, colored, vitaminous, nectarous,

resinous etc. Among the useful plants are feed plants. It is possible to see these feed plants especially

in vegetations o f Turkey such as desert, steppe, grass, forest, mountain steppe, mountain grass,

subalpine and alpine grass (3). Some feed plants occur individually whereas others arc spreaded as

monodominant covers in the field.

A considerable part o f Turkey display arid properties. Especially, the S and the SE Anatolia fiat

lands show arid characteristics. The vegetation o f these areas are steppe type. Usually it is possible

to see succession process toward becoming a desert. It is important to prevent the process o f

becoming a desert, and then convert the vegetation in a land useful for pasture. For this purpose it is

important to determine the feed piant types that grow in this area. It is another problem to form a

culture-pasture agrophytosenose that is consisted from these species.

Some o f these plants are the species that belong to the

Onobrychis

Miller (

Fabaceae

) genus.

There are 51 species o f

Onobrychis

in the Flora o f Turkey (2,4). With the last revision o f this genus,

it is understood that the number o f these species is around 53 (5).'

Most o f the species that belong to the

Onobrychis

genus has important properties as feed

plants. Among these species,

Onobrychis viciifoiia

Scop.,

O. transcaucasica

Grossh. arc cultured.

For example the value o f

О transcaucasica

as a feed plant is higher in its phenophase. For this plant

some o f the values are as follows; humidity 77%, hygroscopic water 7,76%, ash 6,85%, protein

20,80%, lipid 4,84%, cellulose 21,81%, nitrogenless extracts 48.98% (6).

O. transcaucasica

spreaded over Turkey.

Onr results sliowed that these species are commonly encountered in Turkey's arid regions,

especially in Malay, Gaziantcp. Urfa and Diyarbakir. Table 1 shows the

Onobrychis

species that has

importance as feed plants.

All o f the species given in Table 1 has important properties and values as feed plant. These

species arc eaten well by sheep and cows. It is possible to form cultures of these plants it! arid
