Influence of heading heights of the tree leader on growth and fruiting of sweet cherry
A study was carried out at the Institute of Agriculture, Kyustendil, Bulgaria from 2009-2012 with the objective of evaluating the effect of pruning on the growth and reproductive behaviour of the main sweet cherry cultivars grown in our country - 'Bigarreau Burlat', 'Bing' and 'Van'. The trees were grafted on Gisela 5 rootstock and planted at a distance of 4×2.5 m. Three pruning treatments composed of stem heading height (70, 110 and 150 cm) were imposed annually. As heading height decreased, trunk diameter and fruit size increased. From an economic point of view, the highest net incomes was obtained for 'Bing' shortened to 70 cm height of the stem which had a gross production value of 1195.25 lv da-1 and the net income of 638.38 lv da-1.
