The subject of the research presented in this paper is the impact of surface-earth covering on the watering regime and reproduction potential of the sour cherry cultivar Oblacinska, in the period of its growth. The experiment included fruit trees of various age (one-year, two-years, and three-years old fruits). The covering of earth was done at the beginning of June, after the abundant rainfall of spring and the variants of the earth covering that were used were the following: black foil, white foil, organic (plant) material (rotting straw), manual piling of earth, control without cultivation. The width of the covered zone was 2 m in all of the cases. The remaining space in between the rows was maintained in the state of infertile fallow. In the variant of applying black foil as the covering material, the average content of the soil humidity at the depth of 0.0 to 0.30 cm was 17.3%, ranging between 17.3-17.2% in various-age trees. For white foil, the humidity average was 16.9% (17.6-16.1%). Favourable results were produced by use of rotting straw as well, with the average humidity recorded at 17.4% (17.7-17.2%). In the cases when the classical soil cultivation measures are used, the results lag behind the ones described above, since the recorded average humidity was 15.8% (16.6-14.9%), and the same can be said of the control variant, where the recorded average humidity was 13.1% (13.2-13.0%).
