Summary
Because of the interdiction of chemical seed treatment, smut resistance is a main demand for cultivation of winter barley in organic farming. A comparison of common high yielding varieties with those chosen particularly with regard to good smut-resistance or tolerance showed no significant differences in field performance under the conditions of organic farming. Main criteria were the yield of grain and the content of protein and most important amino acids for animal nutrition (Cystine, Lysine, Me-thionine, Threonine, Tryptophan). Besides this the degree of shading weeds was estimated by means of measuring leaf areas and lengths of stalks. The leaf area proved to be the main factor. The availability of smut resistant or tolerant varieties out of organic production is not satisfying yet.
