The field experiment was conducted on good rye soil in 2002-04. Kobra cultivar of winter wheat was grown as a continuous crop at different levels of reductions in post-harvest and pre-sowing soil tillage. The control treatments were: wheat grown in crop rotation (winter rape-winter wheat-spring barley) and wheat in continuous cropping under conventional tillage. The yield of wheat depended significantly on crop sequence and on method of soil tillage. Under conventional plow-based soil tillage, growing wheat as a continuous crop reduced its grain yield by 17.3 percent, and also distinctly: plant height, grain weight per head and thousand grain weight, compared with wheat in crop rotation
