The work presents results of studies conducted from 2008 to 2011 to determine the effect of undersown catch crops, which were either autumn-incorporated or left on the soil surface as mulch for spring incorporation, on the content microelements in potato tubers cultivated in various production systems. The following two factors were examined: I. - manuring with an undersown catch crop: control, farmyard manure, white melilot, white melilot + westerwolds ryegrass, westerwolds ryegrass, white melilot applied as mulch, white melilot + westerwolds ryegrass applied as mulch, westerwolds ryegrass applied as mulch; II. - production system: integrated and organic. Potato tuber samples were taken to determine microelements. The results demonstrated that manuring of potato with undersown catch crops, in particular autumn-incorporated white melilot, increased iron, zinc and boron contents, and reduced copper and manganese contents in potato tubers. Potatoes cultivated in the integrated production system had a higher concentration of copper, manganese and zinc whereas organic tubers had more iron and boron.
