Abstract :A field experiment was conducted in the Wielkopolska region insert ignore into journalissuearticles values(52◦29’ N, 16◦49’ E, Poland); in Central Europe. The study was conducted over a 3-year period insert ignore into journalissuearticles values(2008, 2009, 2010); as a two-factorial desingn with four replications in the randomised plots The first factor consisted of lupin species insert ignore into journalissuearticles values(S);: yellow lupin insert ignore into journalissuearticles values(YL); and narrow-leaved lupin insert ignore into journalissuearticles values(BL);; the second factor was the adopted soil tillage system insert ignore into journalissuearticles values(TS);: conventional tillage insert ignore into journalissuearticles values(CT);, reduced tillage insert ignore into journalissuearticles values(RT); and no-tillage insert ignore into journalissuearticles values(NT);. The following tillage systems were applied continuously since 1997 insert ignore into journalissuearticles values(before 1997 CT was used);. YL compared to BL developed significantly higher stems, a greater plant mass, more pods and seeds per plant, but the number of seeds per plant pod and the mass of 1000 seeds were not differentiated between S. The seed yields of lupins were very similar and amounted to 1.15 t ha-1 for YL and 1.01 t ha-1 for BL. NT decreased significantly the plant density both lupin species. The seed yields of both lupin species were very similar and there were not significant differences between TS. For this reason both lupin species may be cultivated in simplified soil tillage systems without losses of seed yields. Key words: narrow-leaved lupin, tillage systems, yellow lupin
