ABSTRACT:
The purpose of this study was to determine the influence of the soil fertilizer UGmax on zinc, copper and manganese contents in potato tubers. A three - year field experiment was carried out on soil which belonged to a very good rye complex. The experiment was established according to randomized split-plot method, in three replications. The following factors were examined: factor I: edible potato varieties (Satina and Typhoon), and factor II: doses and timing of UGmax application. As a result of conducted research, significantly smaller copper content in potato tubers was found, after usage of the soil preparation UGmax, in comparison with a control object, while zinc and manganese content continued to show only a downward trend. The influence of weather conditions and potato varieties on the copper cumulation in the dry mass of potato tuber was proved. An important influence of the factors of the experiment on the uptake of researched macroelements with the potato tuber yield was also shown.
