The experimental data of 2011-2012 on influence of chelate foliar fertilization on fructification, quality and pear fruits preserving of Belorusskaya pozdnyaya on a dwarf quince S1 rootstock are presented. Chelate foliar fertilization has made the positive influence on productivity, marketable quality and preserving of pear.
Scientific-based use of clonal rootstocks of fruit crops is one of defining factors of increase in efficiency of horticulture and providing the competitiveness of domestic products. According to the Agreement for creative cooperation, in RUE Institute of Fruit Growing (Belarus) the apple rootstocks NC (North Caucasus) series of the North Caucasian Federal Scientific Center of Horticulture, Viticulture, Wine-making breeding are tested. According to the opinion of authors and other researchers, these rootstocks are characterized by a positive impact the adaptability and productivity of grafted varieties. The article presents the results of evaluation of economic and biological apple rootstocks properties of NCFSCHVW breeding in the maternal rootstocks plantings, in the fields of nursery formation and in the garden. On the most of the indicators the dwarf rootstocks of 3 and 4 is close to the standard 62-396; the advantage of 4 rootstock is identified by productivity of the maternal bush (8.1 compared with 7.5 pieces/mat. bush). The condition of Imant apple trees for 10 years after planting in the garden was better on the rootstocks of 3 (3.7 points) and 4 (4.2 points) than on the control rootstock of 62-396 (3.0 points). Safety of trees on the 62-396 rootstock was 83.3 %, on the rootstocks of 54-118, 2, 4 100 %, on 3 rootstock 92.0 %. The assessment of the trees strength in the soil (anchorage) showed that 50 % of Imant trees on 62-396 dwarf rootstock have a slope of 1.0 points (weak slope of the tree), on the rootstock the share of trees with a slope of 1.0 points was less up to 33 %. The income of the sale of fruits on the 4 rootstock was more than on the 62-396 rootstock (16 660 and 16 100 rubles/ha) due to better preservation of trees and higher marketability of fruits.
