The aim of this study was to assess the value of sowing and the vigor of narrow-leaved lupin depending on the crop production system, density of sowing and variety. Laboratory tests conducted in the years 2007-2009 at the Department of Agronomy, Poznań University of Life Sciences, on the grain derived from field experiments of the Agricultural Experimental Station Winna Góra belonging to the Institute of Plant Protection - National Research Institute. In the laboratory experiments evaluated parameters were: energy capacity, germination capacity and vigor using: seedling growth test, seedling growth rate test, Hiltner test, comprehensive stress test. In addition vigor index was calculated and root length and weight of thousand seeds determined. It was found that production system significantly modified the sowing value of narrow-leaved lupine. Seed of conventional crops was characterized by higher parameters of energy capacity, germination capacity and vigor expressed in seedling growth test, Hiltner test, test of comprehensive stress, vigor index. The density of sowing of narrow- leaved lupine, except germination capacity, didn’t influenced the quality of sowing. Among the compared varieties, higher seed value and vigor were observed in Boruta variety.
