English. Influence of application of plant growth regulators (Poteitin; Novosil, Ehpin; and peat hydrohumate) against the background of organic and mineral fertilizers on yielding capacity and quality of potato (Solanum tuberosum) tubers was studied in the conditions of the Republic of Belarus. Application into presowing cultivation of Р60К90 against the background of application at winter fertilization with 60 t/ha of straw cattle manure and dressing of crops with growth regulators on sod-podzolic soil has provided the 193-201 c/ha productivity of potato tubers. Increase of yielding capacity due to plant growth regulators has made 23-31 c/ha. The applied plant growth regulators promoted the increasing of starch and nitrates content.

На дерново-подзолистой рыхлосупесчанной почве внесение в предпосадочную культивацию Р60К90 на фоне применения под зяблевую вспашку 60 т/га соломистого навоза КРС и обработка растений регуляторами роста обеспечило урожайность клубней картофеля 193-201 ц/га. Прибавка урожайности от регуляторов роста составила 23-31 ц/га. Регуляторы роста способствуют увеличению содержания крахмала и нитратов.
