| In a recently started long-term field trial (2002-2011), located in Frick (1000 mm mean annual precipi-tation) near Basle (Switzerland), the effect of reduced tillage on crop yield, weed infestation, and oc-currence of toxigenic fusaria was studied on a heavy soil (45% clay) in a crop rotation under organic farming conditions. Here, we present results of the first two experimental years (2003-2004), which are considered as the conversion period. Wheat yield was 16% higher (p < 0.001) in ploughed plots than in the plots with reduced tillage (chisel and rotary harrow). In the following year, sunflower yield was enhanced by 5% (p = 0.06) in reduced tilled plots. Reduced tilled plots manifested a higher weed infestation, in particular with Convolvulus... |
