Abstract


The influence of 3 tillage treatments (moldboard plough - MT, chisel - CT, disc-harrow - DT) and 50 rapeseed cultivars (41 hybrids and 9 open-pollinated varieties) was assessed within a 2-year study that was carried out on a cambic phaeozem (RSTS-2003) in Suceava Agricultural Research and Development Station for highlighting farmer oriented crop management options regarding tillage and rapeseed cultivar. MT>CT>DT in terms of yield for the entire period, and all pairwise comparisons showed significant (p≤0.05) differences between treatments. The differences among cultivars of the same seed company were insignificant (p≤0.05). Despite having the highest costs, MT remained the most efficient tillage option in Suceava Plateau when compared with both minimum tillage treatments.
