In the conditions of the Republic of Belarus there were analyzed 3-year data of cost efficiency data of leaf-feeding application of produced in Belarus water-soluble macro-fertilizers in fructifying orchard on two highly scab resistant Belarusian cultivars Nadzeyny and Belorusskoye Sladkoye on dwarf rootstock 57-545. There was marked a different reaction of apple cultivars on foliar application of water-soluble fertilizers. The cultivar Nadzeyny had higher yielding capacity after the leaf-feeding fertilizing with potassium phosphate and a complex of potassium nitrate and potassium phosphate. In cultivar Belorusskoye Sladkoye there was not stated yield increasing after leaf-feeding fertilizing. The average fruit mass was higher in both cultivars after application of 1% potassium phosphate solution. Storage and keeping quality indexes of both cultivars Nadzeyny and Belorusskoye Sladkoye were better after application of 1% solution of potassium phosphate or 1% solution of potassium nitrate. The cultivar Nadzeyny had higher cost efficiency after leaf-feeding application of 1% solution of potassium phosphate; the cultivar Belorusskoye Sladkoye had higher cost efficiency in any variants of water-soluble fertilizers applying in comparison with a complex mineral fertilizer.
