Der Einfluss von Minimalbodenbearbeitung, Zwischenfrüchten, Frischmulch und Kompostdüngung auf die Entwicklung der Kraut- und Knollenfäule

Summary in the original language of the document

Reduced tillage combined with about 10cm of fresh mulch of a mixture of green peas and rye was compared to a system with conventional tillage with a plow for its effects on disease development of Phytophthora infestans. Within tillage treatments the precrops for potatoes were weedy fallow, vetch (Vicia sativa), or a mixture of oilseed radish and black oats with or without compost application. The Area Under the Disease Progress Curve in the minimum tillage and mulched plots was on average 881 while in the plowed plots it was 1336, a highly significant difference. Yield data are currently being analyzed and will be presented.
