In 1981-83 under the different agroecological conditions on representative soil types: alluvial soils (NP), alluvial gley soils (NPg) and illimerized soils (IP) in the East Slovak Lowlands, problems of crop rotation were examined. The dependence between the yield of winter wheat and the infestation by stem break was observed. With the higher intensity of plant infestation the yield of winter wheat decreased by 19.3 percent (1,2 t.ha-1) to 46.8 percent (3,4 t.ha-1) depending on the soil types. The greatest yield depression of winter wheat was found out in low fertility soils
