Einfluss des Saatzeitpunktes ausgewählter Sommerweizen¬sorten auf Ertrag, Qualität und Krankheits- und Schädlingsbefall

Summary

Achieving high baking quality and sufficient yield is often a challenge in organic wheat production. The impact of sowing date (either autumn or spring) was compared regarding grain yield, baking quality and infestation with chloropid gout fly of seven varieties of spring wheat. The field trial was conducted in 2010, 2012 and 2013 on a sandy loam nearby Freising, Bavaria.
Two varieties showed higher grain yield after autumn sowing compared to spring sowing in two of the three years. But the opposite occurred consequently for two other varieties. The other three varieties showed no consistent reaction. This different reaction may refer in the majority to a different infestation with chloropid gout fly. Additionally, a higher baking quality (protein content, wet gluten content, loaf volume) was analyzed for spring sowing compared to autumn sowing.
