Abstract
The experiment was performed in the Maritsa Vegetable Crops Research Institute, Plovdiv and Experimental station, Samokov during the period 2009-2011. The aim of this study was to investigate yield structure in the production of certified seeds from Bulgarian potato varieties. Three factors field experiment was set with 12 combinations with established effect of the factors - fertilization rate, planting density and term of leaf striping on the yield of the variants. The total yield in production of certified seeds from Bulgarian potato varieties varies from 2282 to 3556 kg/da. The standard yield of the seed fractions increases significantly with the increase of planting density and decrease of the duration of term of leaf striping.
