Our studies aimed at determination of the effect of fertilization with various doses of ionic or elementary sulphur applied into soil or foliar on the yield of crude oil obtained from 'Star' spring rape seeds and on the contents of essential fatty acids (EFA) myristoleic (C14:l), palmitooleic (C16:l), oleic (C18:l), eicosenic (C20:l) and saturated fatty acids (SFA) palmitic (C16:0) and stearic (C18:0) in the Star spring rape seeds.

It was found that sulphur at the dose of 20 kg x ha , independently of the form (ionic and elementary) had an insignificant effect on the total amount of the oil obtained. The amount of oil obtained was significantly decreased as the dose was increased to 60 kg x ha"'.

Fertilization with sulphur stimulated increase of EFA total contents and decrease of unsaturated fatty acid contents in educed oil. The highest total increase of EFA and simultaneously the decrease of SF\ contents were obtained while applying sulphur in elementary form to the foliar.

The content of individual acids was dependent both on the form (ionic, elementary) of sulphur applied and the method of its dosage (into soil, foliar). It was pointed out that fertilization with elementary sulphur stimulated the increase of oleic, linolic, palmitooleic and stearic acids contents, however it caused the decrease of eicosenic and palmitic acid contents. Fertilization with ionic sulphur stimulated the increase of oleic and palmitooleic acid contents and decrease of eicosenic, palmitic, linolic and stearic acids contents.
