Parameters of apple tree crowns depending on the crown shape and pruning time

The apple tree is a leading fruit crop in Ukraine terms of production volumes and planting areas valuable food product with high content vitamins. In new modern plantings, producers prefer intensive cultivation technologies that ensure the maximum amount high-quality yield per unit area. main criterion for solving this problem design plantings: narrow-row scheme trees low-volume crown shape. purpose study was to establish influence pruning period different types formations on growth productivity two varieties: Fuji Honey Crisp. conducted conditions central Forest-Steppe (Uman National University Horticulture). 4x1 m, M.9 rootstock, chernozem sod-podzolic soil, drip irrigation. Field, statistical, computational-analytical methods were used course study. It identified pattern examined varieties differed substantially, volume, projection area, development feeding area prevailed Crisp trees. However, productivity, plantings variety substantially exceeded values variety. Forming ballerina removal overgrown wood 25 cm zone trunk above lower tier semi-cellular branches provided an increase activity by 3-5%. A substantial decrease parameters formation French axis – there diameter 44%, volume 67%, 69%. Performing additional summer also helped reduce 6-11%. specific doubled 45-50% introduction double recommended agricultural investigate forms, considering varietal characteristics, create compacted stands intensification
