Název v původním jazyce

The effect of urea and urea with urease inhibitor on the content of macronutrients in tubers and tops of potatoes (Solanum tuberosum L.)

Popis výsledku v původním jazyce

In two-year small-plot field experiments in Žabčice u Brna we explored the effect of nitrogen fertilisation with urea and urea with urease inhibitor (Urea + UI) on the content of macronutrients (N, P, K, Ca, Mg) in tubers and tops of potatoes of the variety Karin. The experiment involved 7 treatments. Both fertilisers (Urea, Urea + UI) were reflected irregularly in the contents of N, P, K, Ca, Mg in the potato biomass and were based on the weather of the year, rate of fertiliser and analysed plant organ(tuber, top). In both years the contents of N, K, Ca and Mg were higher in the tops. The P content was balanced both in the tops and tubers. Some changes in the chemical composition were observed particularly in the case of nitrogen. In 2010 the nitrogen content was higher in tubers after the application of both of the higher rates of urea + UI than after the application of urea alone. In 2011 the N content in tops decreased when the highest rate of N was applied in both fertilisers, as
