In the conditions of the Republic of Belarus there were presented the results of studies made in 2011 – 2012 in an orchard planted in spring 2010 by two-year-old seedlings of apple (Malus). The cultivars 'Nadzejny' and 'Irnant' were inoculated on the stocks 54-118 and 106-13. Planting schemes: 4.0 x 1.5 m (density – 1666 trees per hectare) and 4.0 x 2.0 m (density – 1250 trees per hectare). It is established that a clonal stock 54-118 use in intense apple orchard at planting density of 1250 – 1666 trees per hectare supplied earlier flower bud initiation and earlier cropping in comparison with trees on the stock 106-13. On the 3rd year after planting bigger productivity (42,9 tons per hectare), the greatest profit and level of profitability of 166,3% were received at the cultivar 'Nadzejny' on the stock 54-118 at the planting scheme 4 x 1.5 m (1666 trees per hectare).
