Аннотація: The article presents the results of the research, aimed at studying the influence of doses and methods of fertilizer application and mass of planting material on the formation of the yield, seed productivity and yield structure of potato tubers in conditions of Vinnytsia region. As a result of the researches carried out by us during 2019-2021 it was established that the yield and yield of seed potatoes change depending on a dose and a way of application of fertilizers, weight of garden tubers and variety features. The highest indicators of structure of a crop yield and yield were received on the variant of experience, where on a background of action of the half-digested manure brought under the precursor and phosphorus-potassium fertilizer under the basic potato processing were brought into rows (locally) Nitroammophoska (N45Р45К45). At the same time, the number of tubers under a bush increased from 9.0 to 9.5 pieces and the average weight of tubers from 78.1 to 79.5 g, the yield increased from 38.3 to 41.1 t / ha with increased fraction of seed tubers . At intensification of potato growing the highest rates due to varietal peculiarities of Granada variety tubers yield, the size of which on the greatest transverse diameter of 28-60 mm were obtained on the experiment variant, where on the background of half-digested manure introduced under the predecessor and phosphate-potassium fertilizer under potato, into rows (locally) Nitroammophoska (N45Р45К45). At the same time, the share of tubers of this fraction varied depending on the weight of planting material from 44.9 to 54.6%.
