The Effect of Urea and Urea with Urease Inhibitor on the Yield and Content of Essential and Non-Essential Amino Acids in the Tubers of Potatoes

Popis výsledku v původním jazyce

The aim of 3-year experiments was to determine the effect of nitrogen fertilisation with urea (46% N) and urea with urease inhibitor (UI) - NBPT (Urea stabil fertiliser) on the yield and content of essential and non-essential amino acids in tubers of potatoes of the variety Red Anna. The small-plot experiment involved 7 treatments: 1) 90 kg N/ha - Urea; 2) 72 kg N/ha - Urea; 3) 54 kg N/ha - Urea; 4) 90 kg N/ha - Urea + UI; 5) 72 kg N/ha - Urea + UI; 6) 54 kg N/ha - Urea + UI; 7) unfertilised control. These fertilisers were applied on the soil surface and incorporated into the soil during planting. Tuber yields were significantly affected by the year, the 3-year average ranging between 27.3 and 32.9 t/ha, and the yields were the lowest in the unfertilised treatment. Yields were significantly lower only in two treatments (3 and 7) as against treatment 1. The year also significantly affected the content of amino acids (18.94-21.57 g/kg essential and 32.06-35.13 g/kg non-essential amino acids as the 3-year average). It was surprising that the lowest content of both the essential and non-essential amino acids was associated with the highest rate of urea (treat. 1). The highest rate of urea with IU (treat. 4) significantly increased the content of both amino acids in contrast to the highest rate of urea (treat. 1) and in terms of essential amino acids also in contrast to treatments 6 and 7. The efficiency of the urease inhibitor usually lasts 1-2 weeks and is affected by a number of factors. For more objective conclusions it would be desirable to continue in the experiments.
