Abstract

A field experiment was conducted in the Wielkopolska region (52◦29’ N, 16◦49’ E, Poland) in Central Europe. The study was conducted over a 3-year period (2008, 2009, 2010) as a two-factorial desingn with four replications in the randomised plots The first factor consisted of lupin species (S): yellow lupin (YL) and narrow-leaved lupin (BL); the second factor was the adopted soil tillage system (TS): conventional tillage (CT), reduced tillage (RT) and no-tillage (NT). The following tillage systems were applied continuously since 1997 (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.
