The apple cultivars 'Discovery', 'Jonagold' and 'Mutsu' were planted in 1980 at row distances of 3 and 4.5 m. Tree heights of 1.5, 2 and 2.5 m were established at 3 m row distance, and 2.25, 2.75 and 3.25 m at 4.5 m row distance. The tree heights were effective from 1985-86; yield and fruit development were followed during 1982-90. Yield per tree, tree size and fruitfulness were larger at the wider row distance, especially for 'Mutsu'. Thus, in 'Mutsu', yield per hectare at 4.5 m equalled that at 3 m, contrary to 'Discovery' and 'Jonagold', where yield per hectare was higher at 3 m. Also, dry matter contents and colour development ('Jonagold') were improved by 4.5 m row distance in several cases. Reduced tree heights decreased yields and colour development ('Jonagold'), but with minor reductions at tree heights of 2.0-2.5 m during the first 7-8 years. A tree height of 1.5 m, at 3 m row distance, responded negatively, especially for 'Discovery' and 'Jonagold'. |
