| Abstract | The paper presents the results of three-year (2000-2003) experiments to determine the effect of the date of sulfur application (fall + spring or spring only) and the fertilizer rate (0, 30, 60, 90 kg⋅ha-1) on the usability of winter rape seeds. The pre-sowing and the spring rates of sulfur as well as the rate applied entirely in the spring did not lead to significant variations in crude fat concentrations, but a clear tendency towards an increase in the total protein content was observed in rape seeds. A one-way increase was reported to the level of 60 kg S⋅ha-1. An increase in the sulfur rate (regardless of the date of application) to 90 kg⋅ha-1 raised the concentrations of alkene glucosinolates, mainly gluconapin and progoitrin, and – to a lesser degree – of indole glucosinolates, mainly 4-hydroxyglucobrassicin, in rape seed cv. Lisek. The splitting of the total sulfur rate into two rates (fall + spring) caused a higher increase in the concentrations of gluconapin, progoitrin and 4-hydroxyglucobrassicin than a single rate application in the spring. |
