The study on different varieties of wild oat competition in spring barley was carried in 1989 and 1990y. 10 varieties of Avena fatua in 4 densities ( 0, 16, 32, 64 plants per m2) were sown with spring barley. Each variety had different influence on the yield and elements of its structure. On the tillering the highest had varieties G and C, the lowest D. On a number of grains in a head - the highest - D, the lowest A, B, G, H, I, J and on a mass of 1000 grains the highest - F,I and the lowest - A. Beginning from the density of 16 wild oat plants, the yield of spring barley is lowering significantly. This is due to lower number of grains in the head
