Within 2005-2010 years of the research sweet cherry growth and fruiting of three following varieties 'Syubarovskaya', 'Gastinets' and 'Vityaz' on the seed rootstock of wild cherry tree were studied in the orchard of 2005 planting year in the conditions of the Republic of Belarus. Trees planting scheme in the orchard was 4.5 x 3.0 m at planting density of 740 trees per hectare. Economic efficiency of their cultivation was calculated. According to the investigation, trees growth vigour and yield depended on crown pruning forms and on biological traits of the variety. Trees of the variety 'Vityaz' showed the most intensive growth. Formation of natural and improved crown let to more intensive stem growth in thickness and to intensive blossom and also ensured for high initial yield of sweet cherry such as 4.2-6.4 tons per hectare depending on a variety but it didn't influence essentially on one-year-old seedlings growth. At cultivation of the varieties 'Syubarovskaya' and 'Gastsinets' the average initial yield of 6 tons per hectare and more with natural and improved crown formation at trees let getting profit of 3.61 and 4.44 million of the Byelorussian rubles from hectare and profitability appeared to be at the level of 33.9 and 41.2% accordingly.
