The research investigated the impact of the yellow lupin biomass undergoing decomposition in soil on the emergence and initial growth of seedlings of winter wheat and spring barley, depending on the dose and the method of biomass introduction into the topsoil. The laboratory experiment was carried out in the vegetation lab of the Dept. of Land and Plant Cultivation of the Bydgoszcz University of Technology and Agriculture from 1997 to 99. The experiment factors included yellow lupin biomass dose, the method of biomass introduction, namely onto the soil surface, into at the depth of 4 cm, biomass mixed with soil up to the depth of 5 cm, biomass mixed with a soil layer at the depth of 5-10 cm. The results suggest that the impact of yellow lupin biomass undergoing decomposition on the emegrence and initial growth of winter wheat and spring barley depended both on its dose and the method of its introduction into the topsoil. The yellow lupin biomass introduced into soil at the seed sowing depth inhibited the emergence significantly in both cereal species; the higher the dose, the greater the inhibition
