Abstrakt:

Field trails set up on very light and light soil were conducted in 2012-2014. The experiment was designed in triplicates, using the method of random sub-blocks in a split-plot system. The investigated factors were: I – three varieties of edible potato: Bartek, Gawin and Honorata. II – five ways of management: 1. control object – with mechanical weed control; 2. the herbicide Harrier 295 ZC - 2.0 dm3·ha-1; 3. the herbicide Harrier 295 ZC - 2.0 dm3·ha-1 with the biostimulant Kelpak SL - 4.0 dm3·ha-1; 4. the herbicide Sencor 70 WG - 1.0 kg·ha-1. 5. the herbicide Sencor 70 WG - 1.0 kg·ha-1 with the biostimulant Asahi SL - 1.5 dm3·ha-1. The aim of the study was to determine the influence of herbicides and biostimulants on the content and uptake of the selected macroelements: phosphorus, calcium and magnesium, with the yield of potato tubers. The content of phosphorus, calcium and magnesium and their uptake with the yield of tubers depended significantly on the varieties, weed control and weather conditions during the growth season. The highest mean phosphorus content was found in the variety Bartek and the highest mean levels of calcium and magnesium were determined in the variety Honorata. The variety Honorata was also distinguished by the highest ability to take up macroelements with the yield of tubers. The highest content and uptake of phosphorus, calcium and magnesium were noted in tubers collected in the treatments (4, 5) where a mixture of Sencor 70 WG herbicide at a dose of 1.0 kg·ha-1 with the Asahi SL biostimulant at a dose of 1.5 dm3 ha-1 was used.
