In the'experiments were investigated possibilities recompensation yield losses of winter and spring different cereals species, caused by unsown area of travel paths. In the cases when unsown travel paths were established during sowing, the plants of border rows gave higher yield than another plants situated between travel paths. It is because, the plants of border rows have relatively better conditions of growing. The most high yields were reached by winter wheat (104%). The lowest yield gave spring barley (61%). There was noticed some positive influence rows neighbouring border on level of yield. The increase of yield in border rows is caused by different factors depend of species. For winter and spring wheat, rye, winter and spring triticale and winter barley the most important is number of ears per 1 meter of row and number of grain in the ear. For spring barley most important is only number of ears per 1 m of row. For oat the most important is number of grains in the panicle. Theoretically calculated reduction of the yield amounted to 0.7% for winter wheat and for winter barley and 4.2% for spring barley when the distance between pairs of paths is 8 metres (the unsown space amounted to 8%).Analogicaly calculated reduction of the yield amounted to 0.4% for winter wheat and winter barley and 1.8% for spring barley when the distance between pairs of paths is 18 metres (the unsown area amounted to 3.6%). In the cases when travel paths were established during vegetation of plants did not notice influence the travel path on yields increase of border rows. In connection of this, was not noticed any recompensation yield losses as the effect of mechanical destroying plants caused by tractor wheels.
