ABSTRACT

The aim of the present research was to define the effect of sulphur nutrition on the seed yield of ‘Star’ spring oilseed rape and the content of glucosinolates. Sulphur was applied in different forms (elemental or ionic), in different ways (through soil or leaves) and doses (0, 20, 60 kgˇha^-1). The laboratory research material involved seeds from a three-year field experiment set up on degraded black earth containing 1.93 mg SO₄ˇkg^-1 of soil. The content of glucosinolates in seeds was determined with the HPLC according EN ISO 9167-1. The application method and sulphur forms and doses increased the oilseed rape seed yield. The highest mean seed yield was obtained from plants exposed to foliar fertilisation with elemental sulphur at the dose of 60 kgˇha^-1. In this case the content of glucosinolates amounted to 10.78 µMˇg^-1 of dry matter and was lower as compared to objects non-fertilised with sulphur. A total content of glucosinolat

Key words: oilseed rape, fertilisation, sulphur, glucosinolates.
