Kurzfristige Wirkungen organischer Düngemittel mit unter-schiedlichem C/N-Verhältnis auf den Ertrag der Ackerbohne (Vicia faba L.) und Folgefrucht Winterweizen (Triticum aestivum L.) sowie Unkrautwachstum

Summary

The cultivation of grain legumes is important for sustaining nitrogen availability in organic farming systems, but poses problems with weed suppression and plant diseases. To improve soil conditions and nutrient availability for growing grain legumes in organic farming, green chop, horse manure and vegetable compost were applied to faba beans in a field test in 2009 and 2010. Equivalent yield performance after application of these organic fertilizers to faba beans was found compared to the control (without fertilization) and higher yields of the follower crop, winter wheat, resulted. After applying green chop, a strong suppressive effect on the growth of annual weeds was observed.
