In the conditions of the Republic of Belarus in 2005-2009 there was analyzed growth and yielding capacity of sour cherry (Prunus cerasus L.) trees cv. Vyanok and Nort Star on rootstocks wild cherry, Izmaylovsky (PN) and OVP-2 depending on planting schemes 4 x 1.5 m; 4 x 2; 4 x 2.5 m. The variety differences of growth strength, flowering intensity and yield were established on cherry trees. The cross-section area of cv. Vyanok trees was in 1.12-1.24 times higher than of cv. Nort Star. Decreasing the spacing between the trees led to reducing of the bole cross-section area of cv Vyanok on OVP-2 and cv. Nort Star on PN. The trees yield of cv. Nort Star was in 2-2.5 times higher than the one of cv. Vyanok. The two-year yield of both cultivars was higher on the rootstock Izmaylovsky. The compaction of the cv. Vyanok trees to 1.5 m was appropriate only on OVP-2. The wild cherry and Izmaylovsky rootstocks using with 2 m spacing between trees gave the higher yield per hectare than OVP-2. The profitability had close relation to the yield. The most profitable was using cv. Vyanok on Izmaylovsky at planting scheme 4 x 2 m and using cv. Nort Star on OVP-2 and Izmaylovsky at scheme 4 x 1.5 m.
