The aim of the investigation was to evaluate the possibility to ensure yield of 20 – 25 t haE-1 in different orchard systems. Flowering data obtained during 11 years are summarised. Influence of orchard system on the number of inflorescence per tree at the whole period of investigation is stated, but on the number of inflorescences per orchard area it is stated during the first eight years. Only in some years influence of orchard systems on intensity of flowering was observed. To obtain yield 20 – 25 t haE-1 correspondent vegetative growth or crown volume should be ensured. In the trial desired crown volume was reached only at the 7 – 9 year of experiment.
