    OPTIONS FOR USING VARIOUS MINERAL NITROGEN FERTILIZER APPLICATIONS IN POTATOES

  • Original language description

    Between 2010 and 2014 a field trial was established comprising various dates and ways of mineral nitrogen fertilizer applications in order to compare conventional mineral fertilizer broadcasting prior to planting (urea, DAM 390) and liquid mineral fertilizer application into ridges after potato crop emergence with an applicator (DAM 390). Particularly, an effect of trial variants on potato yield, nitrogen content in foliage dry matter and nitrate content in tubers was observed. Yield results were not statistically significantly affected by trial variants. The tendency to higher yield in individual years was found in the variant with split nitrogen rate, 50 kg.ha-1 of DAM 390 broadcasted prior to emergence and 50 kg.ha-1 of DAM 390 after emergence using an applicator.
