A study was conducted to determine hay and crude protein yields of cereal-vetch mixtures under the rainfed conditions of central Anatolia. Barley (Hordeum vulgare L.), rye (Secale cereale L.), Hungarian vetch (Vicia pannonica Crantz.) and wooly-pod vetch (Vicia villosa Roth.) were grown alone and in combination with each other in different seed compositions following barley harvest. A two-year wheat-fallow rotation system was used in the central Anatolia to overcome a water deficit in the wheat. Higher hay yields were obtained from all treatments in the 1979/80 crop season than in the 1980/81 crop season. Cereals grown alone produced 20 and 46 percent and vetches 52 and 28 percent lower hay and crude protein yields than the crops grown as mixtures, respectively. Increasing the ratio of cereals in the mixtures increased hay yield but not crude protein yield. Cereal and vetch mixtures for hay production seemed to be better alternative feed sources than vetches grown alone. Higher crude protein content and hay yields from mixtures could be explained by a positive association between vetches and cereals and by readily available N forms fixed by vetches for cereal usage
