This work is aimed at solving the actual problem of increasing in the fruit plants productivity. The research presents the results of studies of top dressing efficiency by �Lignohumate� fertilizer for fruit crops under the conditions of the Crimea Republic, the impact the yield and the quality of the fruit products is assessed. The analysis of the influence of seasonal conditions and the usage of fertilizers the main indicators of the studied fruit crops was done. The experimental research was carried out during 2018-2020 on apple-tree of Spartan variety (JSC Artvin, Bakhchisarai district), on peach-tree of Red Haven and sweet cherry of �igarrean Burlat (Agropolis farm, Kirovsky District). It is established that the use of �Lignohumate� foliar fertilizing increased in average length of annual shoots in the studied crops from 14.7 % (peach) to 16.5 % (apple). Mathematical analysis of the results showed that the share of seasonal influence the annual shoots growth rate varies in the interval 8,7 % (sweet cherry) � 55,0 % (peach), at � < 0,05. Top dressing of plants increased in chlorophyll concentration in apple and peach leaves by 14,0 and 13,2 %, respectively; mass concentration of sugar in apples by 6,1 %, and in peach by 7,5 %; in sweet cherry by 16,1 %; solid substance content in the fruits � by 0,9 % (peach) 1,7 % (apple). Also it is shown that the use of �Lignohumate� top dressing of plants increased in the content of mineral elements in the studied crops, relative to a control group, and the yield on average 16,3-20,6 %.
