The experiment was conducted at the Research and Didactic Station of Poznań University of Natural Sciences (52^o29' N; 16^o49' E). The aim of the research was to evaluate the effect of tillage systems: ploughing system (traditional), no-ploughing system (reduced) and zero system (direct sowing), foliar microelement fertilization (Mikrosol, Ekolist and Wuxal) and harvest methods (two-stage – of entire plants and pods only, one-stage – manual and with a combine harvester) on the quality of seeds of the yellow lupine variety Parys. The seed vigor was determined with the conductivity test, seedling growth test and seedling evaluation test. Additionally, the vigor index and seedling length sum were calculated. The tillage systems and foliar fertilizers applied did not affect the germination capacity and vigor determined by the conductivity test and vigor growth tests. Yellow lupine seeds from two-stage harvest of entire plants and one-stage harvest with a combine harvester were characterized by the highest germination capacity. Seeds harvested with a combine harvester or the seeds from two-stage harvest of entire plants also obtained the highest parameters in vigor tests. Seeds coming from no-ploughing tillage system, after two-stage harvest of entire plants or combine harvest were characterized by the highest vigor.
