Эксперимент проведен в Институтe овощных культур «Марица», Пловдив и на Экспериментальной станции по картофелю, Самоков в 2009-2011 годах. Целью изучения являлась структура урожая при производстве сертифицированных семян болгарских сортов картофеля. В результате многофакторного полевого опыта установлено влияние нормы внесения удобрений, густоты посадки и срока удаления ботвы на общую урожайность вариантов и их фракции. Урожайность при производстве сертифицированных семян болгарских сортов картофеля Перун, Калина и Боре варьирует от 2282 до 3556 kg/da. Стандартная урожайность семенных фракций увеличивается при более густой посадке и при более раннем удалении ботвы.

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.
