Contents of Zinc, Copper and Manganese in Potato Tubers Depending on the Ways of Application of the Soil Fertilizer Ugmax

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.

A comparative study on proximate and mineral composition of coloured potato peel and flesh

“…The Red Emmalie and Highland Burgundy Red cultivars contained significantly lower contents of Cu in both flesh (3.21 and 3.20 mg kg −1 DM, respectively) and peel (4.01 and 4.55 mg kg −1 DM, respectively). According to other authors, Cu content in the whole potato tuber dry mass is, on average, 3.0 to 13.7 mg kg −1 DM , and it depends on cultivars, growth technologies and weather conditions . Our results are also consistent with a previous report that peels always contain more Cu than the peeled tubers …”

“…However, our values for Mn contents are lower than those established in other studies. Baranowska et al . found that the contents of this element in whole potato tubers ranged from 20.5 to 22.7 mg kg −1 DM.…”

“…However, our values for Mn contents are lower than those established in other studies. Baranowska et al 29 found that the contents of this element in whole potato tubers ranged from 20.5 to 22.7 mg kg −1 DM. In the study of Wszelaki et al, 14 Mn content in the light-flesh potato peels ranged from 25.9 to 99.6 mg kg −1 DM, while for the flesh, it was 11.1 to 16.9 mg kg −1 DM.…”

Influence of organic fertilizers on potato yield and quality in different humidity years
