abstract:
The investigations were aimed at estimating white mustard yielding and its sulphur concentration resulting from supplying sulphur to the soil as multi-component fertilizers and single-component mineral fertilizers containing this element as a by-product. In the first year of the expe-riment dry matter yields of white mustard, either silique or stems with leaves, did not differ significantly between treatments. No marked effect of sulphur supplement or fertilizer containing this element on the amount of mustard aboveground part yield was observed. In the second year of the studies markedly larger yields of plant silique were noted in treatments with sulphur addition applied against the mineral background. The highest total yields of white mustard in both years of investigations were obtained from plants fertilized with multi-component Polimag S fertilizer and in treatments with sulphur applied as ammonium sulphate against NPK background. The highest sulphur content was found in silique. In both years of the experiment a comparable amount of sulphur was assessed in plant silique from Polimag multi-component treatments to those where sulphur was used under mustard as sodium sulphate, but lower than in silique of mustard fertilized with ammonium sulphate. Sulphur concentrations in mustard roots from the treatments where sulphur was applied were higher than in roots of plants fertilized with mineral fertilizers without sulphur.
