Opis:: The aim of the study was to determine the effect of applied herbicides and growth regulators on the airborne limitation of dry weed mass and the total yield of three edible potato varieties. The field experiment was established as two-factor in a (split-plot) system in three replications. The experiment examined: I factor – three moderately early varieties of edible potato: Bartek, Gawin, Honorata. II factor – five ways of using herbicides and bio-stimulants: 1. control object: mechanical care 2. Harrier 295 ZC herbicide at a dose of 2.0 dm³·ha^-1, 3. Harrier 295 ZC herbicide at a dose of 2.0 dm³·ha^-1 and then after the plant rises the Kelpak SL bioregulator twice at a dose of 2.0 dm³·ha^-1, 4. Sencor 70 WG herbicide at a dose of 1.0 kg·ha^-1, 5. Sencor 70 WG herbicide and then after the plant rises the Asahi SL bio-stimulant twice at a dose of 1.0 dm³·ha^-1. The obtained test results showed that the smallest dry weed mass determined in both research dates was obtained using Harrier 295 ZC herbicide and Kelpak SL growth bio-stimulant (0.7 g·m^-2 and 3.1 g·m^-2), while the largest in the control object (15.1 and 64.7 g·m^-2), respectively. The total yield of potato tubers depended on both the types of herbicides and bio-stimulants used and the varieties cultivated in the experiment. However, the weather conditions which varied in particular years significantly influenced both the size of the air-dried mass of weeds and the total yield of potato tubers.

Opis:: 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 dm^3-1 and herbicide Sencor 70 WG in a dose of – 1.0 kg ·ha^-1.

Opis:: A field experiment was carried out in the Agricultural Experimental Station Zawady (52°03’ N; 22°33’E), owned by the Siedlce University of Natural Sciences and Humanities in 2005–2007. The research was designed as a two factors randomized block with three replicates. The factors examined in the experiment included two potato varieties – Irga and Balbina and four weed control methods combined mechanical and chemical for herbicides application: Plateen 41,5 WG (metribuzin + flufenacet), Racer 250 EC (fluorochloridone), Sencor 70 WG (metribuzin), and control object – mechanical weeding before and after potato sprouting. The study was designed to test the influence of weed control methods on nitrates content in consumption potato tubers. The nitrates (V) content depended on the weed control methods, varieties and weather conditions throughout the growing season. The highest nitrates (V) content was determined when weeds were controlled mechanically and chemically using Sencor 70 WG. The study results demonstrated that Balbina had a higher concentration of nitrates (V) compared with Irga.
