Abstract

In the years 2009–2011 in a field trials at Pawłowice (51°09´ N; 17°06´ E), belonging to the Departament of Crop Production, Wrocław University of Environmental and Life Sciences, comparison experiment with sudangrass (variety Akklimat), sweet sorghum (variety Róna 1 and Sucrosorgo 506) and sorghum-sudangrass hybrid (variety GK Csaba, Nutri Honey) was carried out. Sorghum was harvested one time during growing season, sudangrass as well as hybrid of sorghum with sudangrass harvested once or twice during vegetation period. The highest number of tillers before harvest was found on Akklimat variety harvested two times. Sorghum (variety Róna 1 and Sucrosorgo 506) showed lowest tillering and number of tillers before harvest it was significantly lower compared to other sorghum forms. In spite of lowest number of tillers before harvest, highest biomass yield was obtained from sorghum variety: Sucrosorgo 506 (61,18 t · ha^-1) and Róna 1 (57,96 t · ha^-1). The highest dry matter yield was obtained from Nutri Honey varieties harvested one time during growing season. Sudangrass and sorghum-sudangrass hybrid harvested once per season characterise with higher percentage of panicle and lower percentage of stalks and leaves than the same varieties managed with two harvest methods.
