Growth Parameters of Apple Trees of the Aidared Variety Depending on the Rootstock and the Effect of Long-term Fertilization in Monoculture

Background: The results of studies the influence long-term fertilization on parameters growth apple trees Aidared variety seed and vegetative M.4 rootstocks during repeated cultivation dark gray podzolic soil were considered. Methods: research was conducted 1990-2016 in tree plantation Uman National University Horticulture an experiment with use different systems. Result: It found that length shoot experimental depended age periods growth, rootstock options. During period fruiting, weak (19.4-22.2 cm) all variants both due to impact toxin difficult weather conditions re-grown trees. fruiting periods, largest, while it decreased again, which increase fruit yield lack moisture for normal A significant crown volume (by 38 %) observed stock compared M.4.
