Summary in the original language of the document
The effect of the false seedbed technique on weed abundance and yield has been
tested in organically grown winter wheat at 3 trials (2005-2007). The investigations
were focussed on the evaluation of the different effects of the false seedbed and, in
addition, the late sowing date. Early sowing resulted in high weed density and also low
grain yield in all years. Also there was no clear proof, that the false seed bed
technique results in lower weed infestation. Weed density and crop yield were on the
same level as the late sown winter wheat with only one pass of seed bed preparation.
In a long-term the false seedbed might reduce the weed seed bank, but due to the
more intensive soil tillage there is also a high risk of sealing. Therefore the false
seedbed technique can not be recommended especially for silty soils.
