Abstract:

The objective of the study was to investigate the impact of sulphur application on the content and uptake of boron (B) with the yield of potato tubers. A field experiment with potato was conducted in 2009–2011, with S applied in different forms (elemental and K2SO4) and at different rates (0, 25, and 50 kg ha-1).
The content of B in tubers depended significantly on each fertilizer S rate and form. The uptake of boron with dry mass of tubers was equally advantageous in the application of each rate and form with sulphur fertilization compared to controls. No significant effect of weather on the content and uptake of boron tubers was found. The tuber yield and starch content were significantly increased by both the fertilizer S rate and form. A positive correlation was found between B content and B uptake of the yield of tubers. B uptake positively correlated with tuber yield and with a yield of DM and with the yield of starch.
Sulphur applied as sulphate increased the content of SO4-S in the soil. Application of elemental S at a rate of 50 kg ha-1 decreased the pH of the soil. Soil content of total C depended on each rate and form of S applied. No correlation was found between B content and B uptake between the analysed soil parameters. The content of total C in the soil was positively correlated with tuber yield. The pH of soil negatively correlated with tuber yield.
