In the years 1998-00 two field and laboratory studies on the fertilization value of straw of wheat and winter rape were carried out in the experimental station in Pawlowice near Wroclaw (Poland). Winter rape cultivar Silvia was fertilized with straw of winter wheat cultivar Kobra in the first series. Winter wheat cultivar Kobra was fertilized with straw of winter rape cultivar Silvia in the second series. Examined agrotechnical factors have not exerted distinct influence on lenght of growth stage of rape and winter wheat. Winter rape cultivated after ploughing straw of winter wheat, comparing with without straw, were developing slower in autumn, had 12 percent more siliques per plant and had 10 percent more seeds yield and crude fat. Winter wheat cultivated after ploughing straw of winter rape comparing with without straw, had about 5 percent less amount of grains in the ear and 4.3 percent less amount of grains yield
