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 autumnincorporated 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.
