Mulch- und Direktsaat von Soja in abfrierende und überwinternde Zwischenfrüchte

Summary

Growing soybeans, the risk of erosion can be reduced with mulch-tillage or no tillage. A field trial was carried out at one site in 2013 and 2014. Soybeans were sown in six
different frost terminated and four drill with or without seedbed preparation. In 2014, only some plots after winter hard cover crops could be harvested. The weed infestation and the mulch layer were mostly significant higher without seed preparation than with seedbed preparation during soy beans´ growing period. These higher concurrence to soybeans in the variants without seedbed prepartion resulted in significant lower yields of soya.
