The paper examines the influence of tillage systems: conventional, reduced tillage and direct drill, plant foliar fertilization with microelement fertilizers (Mikrosol, Ekolist and Wuxal) and harvest methods (two-stage – entire plants or pods only, one-stage – manual and using a combine harvester) on the quality of narrow-leaf lupin (Lupinus angustifolius L.) seeds of the Zeus cultivar. The vigor of the seeds was determined using the conductometric method, seedling growth test and seedling evaluation test. Additionally, vigor index, the weight of 1000 seeds, and the sum of seedling length were measured. The analyzed tillage systems not so much modified the seeds germination ability, as influenced their vigor. Compared to the control, the analyzed foliar fertilizers did not modify the germination ability and seed vigor of narrow-leaf lupin when combine-harvested and when the entire plants were harvested in two stages. The seeds from combine harvest and two-stage harvest of entire plants showed the greatest vigor and germination considering their vigor index and seedling growth test.
