Planting scheme influence on yield and economic indexes of variety and rootstock apple tree combinations

Abstract

The researches were made in 2011-2012 in an orchard planted in spring 2010 by two-year-old seedlings. The cultivars ‗Nadzejny‘ and ‗Imant‘ were inoculated on the stocks 54-118 and 106-13. Planting schemes – 4.0 х 1.5 m (density – 1666 trees/hectare) and 4.0 х 2.0 m (density – 1250 trees/hectare). It is established that a clonal stock 54-118 use in intense apple orchard at planting density of 1250-1666 trees/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 t/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 х 1.5 m (1666 trees/hectare).
