The field experiment was conducted in the years of 2012–2014 in the Agricultural Experimental Station Zawady belonging to the University of Natural Sciences and Humanities in Siedlce. The two factor experiment was set up in the split-plot system in triplicate. The investigated factors were: I – three varieties of edible potato: Bartek, Gawin and Honorata. II – five ways of care: 1. Harrier herbicide 295 ZC – 2.0 dm³·ha^-1; 2. Harrier herbicide 295 ZC – 2.0 dm³·ha^-1 with the biostimulator Kelpak SL – 4.0 dm³·ha^-1; 3. Sencor herbicide 70 WG – 1.0 kg·ha^-1; 4. Sencor herbicide 70 WG – 1.0 kg·ha^-1 with the biostimulator Asahi SL – 1.5 dm³·ha^-1; 5. The control object – mechanical care. The content of zinc and copper and their collection with the yield of tubers significantly depended on the ways of care, genetic factor and climatic conditions in the years of the study. In the objects (2, 4) where herbicides were used with biostimulators, a greater concentration of zinc was obtained in relation to the control object and the remaining (3, 5) in which only herbicides were used. The applied care methods did not affect the content of copper in the analysed tubers. The greatest collection of zinc an copper with the yield of tubers was obtained in the objects: where the mixture of the Sencor herbicide 70 WG – 1.0 kg·ha^-1 was used with the biostimulator Asahi SL – 1.5 dm³ ha^-1 and herbicide Sencor 70 WG in a dose of – 1.0 kg ·ha^-1.
