ABSTRACT
Data about formations and associations of legume fodder crop group of the steppe vegetation cover of Steppe Plateau have been shown in the paper. Classification of dry steppe plants is limited by 1 type (Steppe), 2 formation classes (shrub-bean-cereal dry steppes and moutley grasses-legunimous dry steppe); 3 formations groups (Astragaletum-Stiposum, Onobrychisetum-Festucosum and Artemisetum-Astragalosum), 4 association class (Astragaletum mollis-Stiposum capillata; Onobry¬chisetum vaginalis - Fe¬stucosum ovina; Ono¬brychisetum iberica-Festucosum giganteum; Artemisietum fragrans-Astragalosum microcephala) and 4 association groups (Astra¬galus mollis + Stipa capillata+ ephemeretum; Onobrychis vaginalis+ Festuca ovina +ephemeretum; Ono¬brychis iberica+Festuca giganteum+herbosum; Artemisia fragrans+ A.caucasica + A.campestris +Astragalus microcephala + Trifolium striatum+Lotus tenuis). Each association contains about 30-45 plant species, in each of which the legumes play role of ecosystem engineering (or plant edificator). Classification of the leguminous group spread around dry steppe area have been compiled.
