Dense Planting Effect on the Productive Capacity of Some Plum Cultivars

Abstract

The basic objective of this paper was to determine the productive capacity of different spindle-trained plum cultivars grown in dense planting at a 4 x 2 m planting distance (1,250 trees/ha). The investigations were carried out in an experimental plantation established in 2001 in the village of Prislonica near Cacak. The used material included the 'Ruth Gerstetter', 'Cacanska Rana', 'Violeta', 'Cacanska Lepotica', 'Cacanska Najbolja', 'Stanley' and 'Cacanska Rodna' cultivars. The cultivars were grafted on 'Belosljiva' (Prunus domestica var. alba) seedlings. Fruit mass (g), yield per tree (kg) and yield per unit of area (kg/ha) were examined. The results showed that in the sixth and the seventh years after planting, the highest yield per tree was recorded with the 'Cacanska Rodna' (16.70 kg) or 23,350 kg/ha. The lowest yield per tree was registered with the 'Cacanska Lepotica' (14.70 kg) or 18,375 kg/ha and 'Cacanska Rana' (14.90 kg) or 18,625 kg/ha. The highest and the lowest fruit masss were determined in the 'Cacanska Rana' (66.70 g) and 'Cacanska Rodna' (25.60 g).
