    Estimation of the Selected Winter Wheat (Triticum Aestivum l.) Varieties Cultivated in Organic and Conventional Crop Production Systems

    Four winter wheat (Triticum aestivum L.) cultivars (Akteur, Adler, Discus, JB Asano) derived from organic and conventional production systems carried out in 2010–2011 at Gülzow (Germany) were evaluated. The wheat samples were analysed for content of dry mass, protein, fat, crude fibre, total carbohydrates and fibre fractions (NDF, ADF, ADL, HCEL, CEL). Grain originated from organic system had on average the crude protein 27% lower than that from conventional one (p < 0.05). It was found, that the winter wheat grain from organic system contained the higher level of total carbohydrates (p < 0.01) and crude fibre than that from conventional one (p < 0.05). The examined cultivars also significantly differed in the content of crude fiber and dietary fiber fractions. The conducted research did not allow an unequivocal determination of the crop production system that would have more beneficial influence on nutritious value of winter wheat grain.
