In the conditions of the Republic of Belarus there were analyzed the results of growth and productivity research of apple (Malus) tree varieties Antey and Tellisaare grown on clonal (small-stature form of stock) rootstock 62-396 and semiclonal (semidwarf) rootstock 54-118 in 1999-2008. Schemes of planting was the following: one-line – 4 x 3 and 4 x 1,5 m with density 833 and 1665 trees/hectare; two-line - (4+1) x 1,5 m with density of 1335 and 2665 trees/hectare. It was determined that more compact scheme of planting reduced the strength of body of a tree growth. Decreasing of area increment of cross-sectional area of stem, as well as size of crown was observed in plantations with thicken scheme of planting on the rootstock 62-396, notably in variants with scheme of planting 4 x 1,5 m and (4+1) x 1,5 m and orchard density 1665-2665 trees/hectare. More vigorous increment of cross-sectional area of stem was noted with scheme of planting of 4 x 3 m and orchard density 833 trees/ hectare. The greatest productivity from area unit for 10 years was obtained in thickened plantings: on rootstock 62-396 with scheme of planting (4+1) x 1,5 m - 54,2 and 32,5 ton/hectare; 4 x 1,5 m - 47,6 and 27,6 ton/hectare; (4+1) x 3 m - 47,5 and 24,6 ton/hectare, respectively. At thinned scheme of planting (4 x 3 m) productivity of variety Antey on rootstock 54-118 was 35,6-37,6 ton/hectare, variety Tellisaare on the same rootstock - 18,4-22,8 ton/hectare.
