Resumo: 	At the experimental farm Wiesengut in Hennef (Germany) in 2007/8 four different  cultivation methods of rapeseed and an application of fertiliser in springtime were  tested in order to manage weeds, to reduce nitrogen losses during wintertime and to  enhance grain yield. Cultivation methods tested included i. narrow row distance (12  cm), no mechanical weed control; ii. wide row distance (24 cm), mechanical hoeing;  iii. rapeseed sown in double rows intercropped with buckwheat (Fagopyrum  esculentum Moench) sown in double rows, row distance 12 cm, no mechanical weed  control; iv. rapeseed sown in double rows and left double rows free, row distance  12 cm, mechanical hoeing. In a two factorial completely randomised block design  these treatments were fertilised (I. 80 kgN/ha as PPL, Potato Protein Liquid) and not  fertilised (II.) in March 2008 at EC 30. In contrast to the hypothesis treatment iii.  (rapeseed intercropped with buckwheat) did not control weeds efficiently nor  enhanced nitrogen uptake before winter. Grain yield was significantly lower in this  treatment compared to all other treatments. The most cost-efficient treatment i.  controlled weeds effectively. Grain yield was not significantly lower in this treatment  compared to the more cost-intensive treatments (ii. &amp; iv.) where hoeing was  performed. Across treatments calculated, application of PPL increased grain yield  significantly.
