The study has been undertaken to assay the effect of soil contamination with diesel oil on yellow lupine yield and macroelement contents as well as to examine the relationships between the accumulation of macroelements versus the yellow lupine yielding and some yield quality characteristics. The influence of soil pollution with refinery products depended on the type of soil, diesel oil concentration in soil and mineral fertilisation. Increasing contents of soil pollution with diesel oil promoted higher concentrations of phosphorus, sodium, magnesium and calcium in aboveground parts and roots of yellow lupine. More severe contamination was also responsible for depressed yield of yellow lupine aboveground parts and roots as well as accumulation of nitrogen in aboveground parts and potassium in roots of the crop. The addition of nitrogen to soil diversified the yielding and content of macroelements in yellow lupine. The direction these changes took depended on the plant organ, type of soil and degree of diesel oil contamination.Keywords:
