Abstract

THE VARIABILITY OF SOME QUANTITATIVE FEATURES INVOLVED IN THE FODDER YIELD AT SAINFOIN (Onobrychis viciifolia Scop.) Sainfoin (Onobrychis viciifolia) is an important fodder plant, adapted to dry or semi-arid areas, where the cultivation of alfalfa or clover is limited to the environmental climax. Sainfoin is a fodder with a very high palatability. It does not induce meteorism when it is used in animal nutrition as green mass. It is a species that has an extremely marked intra-individual variability. The improvement of this species aims mainly at the yield of green and dry mass, the yield of seeds and the fodder quality. There have been observed 20 sainfoin genotypes, situated in the second year of vegetation. Determinations have been made at cuttings I, II and III. The results obtained for the second year of vegetation emphasize the fact that the newly created genotypes are characterised, besides by the regeneration capacity, by an obvious perenniality.
