| Abstract:
An intensive sweet cherry orchard was planted in early spring 1994 at Ahrweiler (western Germany) with the objectives to compare the performance of planting densities between 1666 and 5000 trees per ha where the trees were trained in a V-shaped 30° spindle system and a V-shaped 60° trellis system. The trial included four cultivars: ‘Starking Hardy Giant’, ‘Noire de Meched’, ‘Fercer’ and ‘Lapins’, all grafted on Tabel Edabriz (Prunus cerasus). The first two crops showed a positive correlation between planting density and yield, but also a large influence of the cultivar was observed. Highest yields were obtained by ‘Lapins’ at density 5000 trees per ha. Two different rain covering constructions were established as a part of the trial. The covering systems did not completely prevent cracking and rotting, but gave an efficient protection against frost during flowering in 1997. | |
