Abstract

The optimal planting distance of tree seedlings is a basic requirement for optimal utilization of agroecological
conditions and achieving higher yields. This is especially important when it comes to apple vegetative
rootstocks. Four apple cultivars were included in the research: Idared, Gloucester, Jonagold, Golden Delicious,
grafted on two rootstocks. Idared cultivar is grafted on vegetative rootstock M 9, with planting distance 4 x 1.4 m,
while the other three cultivars have planting distance 4 x 1.6 m, grafted on rootstock M 26. Research was conducted
during 2018 and included vegetative and generative parameters for the aforementioned cultivars and rootstocks.
Research has shown that the Idared cultivar grafted on the M 9 rootstock had a smaller trunk diameter of 24.13 cm while the Gloucester cultivar 28.06 cm grafted on the M 26 rootstock had the largest trunk diameter. The dry matter content in the largest fruit was in the Golden Delicious cultivar (19.37%) while the smallest amount in the Jonagold cultivar (16.97%). Differences between cultivars and rootstocks that were in research for the studied parameters were with high significant differences for both levels 0.05 and 0.01 The development of intensive orchards, represents a more accumulative production with high quality fruits in relation to the achieved yields. Based on practical experience, it has been concluded that the shape of the tree crown is only one of the successful factors in the profitability of fruit production, while all other factors are complementary, such as the number of plants per unit area and the technology of applied, which aims to maintain the most harmonious relations between the number of plants and the shape of the crown
