QUALITY IMPROVING OF APPLE PLANTING MATERIAL BY USING FOLIAR FERTILIZERS

Abstract

In the conditions of Tambov region on leached chernozem soil there was studied the infl uence of foliar nutrition with complex of mineral fertilizers on morphological characteristics and productivity of clonal rootstocks and seedlings. The positive infl uence of additional fertilizing on the yield of annual seedlings was established. The highest effi ciency was provided by treatments with preparations Aquarin and Master (the concentration of working solution was 0,5%). It was noticed the variability of scion-rootstock combinations responsiveness to the additional fertilizing: the most variable there were the varieties grafted on the rootstock 62-396, in comparison with the varieties grafted on the stock 54-118. Among the tested varieties the most responsive to the use of foliar nutrition was the variety Antonovka obyknovennaya grafted on both rootstocks.
