This paper presents grain yields of winter wheat in 3-field crop rotations in relation to forecrops (winter rape and pea) and doses of nitrogen (60, 100 and 140 kg/ha). The experiment was carried out since 1986 on black soil with the granulometric composition of light loam. Results obtained in 1987-91 prove a more favourable effect of pea as forecrop than winter rape on grain yield of winter wheat. N fertilization can be reducted on fertile soil without reducing the yields of winter wheat, when forecrop is pea
