Abstract

Studies were carried out in the two years in Trzcianka near Nowy Tomyśl, on brown soil, IIIa – IVa with pH 7.1 – 7.2. Plants of five maize cultivars were cut at the height of 15 cm and 55 cm. The lower parts of stems with leaves which remain on the field in case of high cutting, were characterized by a smaller content of protein and by a greater content of fibre, in comparison with the higher parts of plants. The energetic value of 1 kg of dry matter of the lower 40 cm part with leaves expressed in MJ NEL, in spite of significant differences in the chemical composition, was only insignificantly lower than the upper part. The content of dry matter, the chemical composition and the energetic value of both parts differed, depending on the cultivar.
