    The field experiment was carried out in the years 2010–2013 at the West Pomeranian University of Technology Experimental Agricultural Station in Lipnik, near Stargard Szczeciński (Poland). The research included the determination of an impact of two weed control methods (mechanical and chemical) and three sowing densities on the yield of selected winter spelt and common wheat cultivars, the yield components and their physiological parameters. The application of a chemical herbicide did not significantly influence grain yielding in 2011 compared to a mechanical weed control method, and increased it in the years 2012 and 2013. An increase in sowing density from 300 to 500 grains per m2 increased the yielding, the number of ears and at the same time, decreased the grain number in an ear. The mass of 1000 grains was similar regardless of sowing density. The highest mean yields in the three years were observed in common wheat Tonacja, lower in spelt cultivars of Plant Breeding Strzelce and the lowest in Oberkulmer Rotkorn spelt cultivar. The responses of spelt various cultivars to different weed control methods and to various sowing densities were similar.
