The effect of the cultivation methods (growth on ridges and flat cultivation) and irrigation on nitrate, cadmium, zinc and copper content in storage roots of the carrot was investigated. The climate conditions of the individual years strongly affected the level of nitrate. Irrigation in the warm and dry months (July and August) in 1995, significantly reduced nitrate content in carrots. Cadmium level did not change significantly during the experiment period (1995-1997), but a tendency of its decrease in the case of ridge growth and in the irrigated treatments was observed. No significant effect of the cultivation methods and irrigation on the other mineral compounds was found.
