THE EFFECT OF DIFFERENT TRAINING SYSTEM ON YIELD AND FRUIT QUALITY OF ‘JONAGOLD’ APPLE VARIETY

The influence of four different training systems (slender spindle, Northern Holland spindle, solex and ‘V’ system) on the productivity of the apple cultivar ‘Jonagold’ have been evaluated.
Research was conducted at two experimental orchard located in Skopje and Resen during 4 consecutive years.
The planting distance was different and according to the training system.
For slender spindle and solex the planting distance was 4 x 1.5 m (1667 trees/ha) and for Northern Holland spindle and ‘V’ system 4 x 1 m (2500 trees/ha). The results showed statistically significant differences between location and between different training systems.
Concerning the productivity, the tree grown under the slender spindle system has the highest yield, whereas the ones from the ‘V’-system had the lowest.
Shown in per hectare, the Northern Holland spindle system is mostly productive.
The solex system had the lowest yield per ha.
The trees on solex training system have the highest yield efficiency, the lowest was observed on slender spindle system.
The highest value for the fruit weight was obtained at slender spindle and solex whereas the ones from the ‘V’- system was with the lowest value for the fruit weight.
