| Abstract:
The study was carried out at the Institute of Agriculture, Kyustendil (Bulgaria). The aim was to compare economic indices of sour cherry production of the ‘Heimanns Rubinweichsel’, ‘M-15’ and ‘Nefris’ cultivars grown on their own roots (trees obtained by in vitro propagation) with trees grafted on seedlings of the ‘IK-M9’ Mahaleb rootstock. The balance value, productivity and economic efficiency of these cultivars were evaluated. The analysis showed that the balance value per one hectare of the own-rooted trees was higher than that of the grafted ones. The gross production of trees grafted on ‘IK-M9’ was higher than that of the own-rooted. The differences were 60.8% for ‘M-15’, 98.9% for ‘Nefris’ and 86.5% for ‘Heimanns Rubinweichsel’. The most suitable cultivar/rootstock combinations, from the economic point of view, were those of ‘M-15’ and ‘Nefris’, grafted on the ‘IK-M9’ rootstock. | |
