The objective of this trial was to evaluate the influence of foliar fertilizers on the content of nutrients in leaves, growth, fruit quality and yield of sweet cherries on dwarf rootstocks. Cultivars Burlat, Vanda, Starking Hardy Giant, Summit and Kordia on dwarfing rootstocks Gisela 5, P-HL-A, P-HL-B and Tabel Edabriz were evaluated in an experimental orchard established in 1998. In addition to the basic fertilization, three foliar fertilizing variants variants were applied: urea, full ration of foliar fertilizers and half amount of fertilizers plus lignohumate. Application of additional foliar fertilizers had positive influence on the tree growth and the yield amount. The trees attained the highest yields after using urea. Application of lignohumate with half amount of fertilizers as well as urea spraying had positive influence on the fruit size. Trees on the Gisela 5, roostock had the highest yield efficiency and in the leaves content of N, Ca and P.
