Ertragsleistung und Rutingehalte verschiedener Buchweizensorten unter ökologischen Anbaubedingungen

Summary

Buckwheat is an ancient traditional food and medicinal plant. In this study we
investigated grain yield and rutin content of common (Bamby, Lileja, Hruszowska) and
tataric (Lifago) buckwheat varieties under organic farming conditions at different N
levels. Grain yield and rutin content were not significantly affected by the factors ‘year’
and ‘N-supply’. However, strong effects of the factor ‘variety’ could be determined. The
tataric buckwheat Lifago showed highest grain and rutin yields compared to the
common buckwheat varieties. Due to the rutin related bitter taste Lifago buckwheat is
rather useful for medical application than for basic food. Converting rutin into less
bitter active substance quercetin during processing as well as cross-breeding of
common buckwheat x wild type buckwheat might be alternatives for basic food
application. Since we found no effect of additional N-supply, buckwheat is well suited
for low input farming systems like organic farming.
