In an experiment carried out in the years 2004-2007 at the Agriculture Research Station Zawady owned by the Podlasie Academy in Siedlce (Poland) the forecrop value was evaluated for winter wheat of post-harvest residues alone or in combination with straw, of spring wheat, faba bean and spring wheat-faba bean mixtures. Post-harvest residue and straw biomass as well as total nitrogen, phosphorus and potassium accumulations were assessed. Spring triticale produced more post-harvest residues and straw than faba bean. Spring triticale-faba bean mixtures in turn produced intermediate amounts of post-harvest residues and straw compared with the plants in question cultivated in pure stand. Spring triticale biomass was poorer in nitrogen and potassium than faba bean and spring triticale-faba bean mixtures. Winter wheat cultivation following faba bean and mixtures of spring triticale and faba bean significantly increased grain yield and total protein yield, compared with winter wheat cultivation after spring triticale. Soil quality increased as faba bean share in the mixture increased. Straw added to forecrop post-harvest residues significantly increased grain yield, number of ears per 1 square m and total protein content and yield
