The aim of the investigation was to determine the response of sowing density on yielding of maize hybrids with different maturity class. The field experiment was conducted in 2009-2012 in the Department of Agronomy at the Poznań University of Life Sciences, in the fields of Experimental and Educational Center Gorzyń, Station in Swadzim. The analysed factor was variety: PR39D60 (FAO 210), PR39T45 (FAO 240), PR38N86 (FAO 280), PR38A24 (FAO 330). The second order factor was sowing density: 6, 7, 8, 9, 10 plants per 1 m2. The investigated hybrids were yielding at the same level: ranging from 103.1 to 105.3 dt·ha-1, except early hybrid PR39D60, which grain yield was significantly the lowest and amounted 89.6 dt·ha-1. Average for the four years of investigation, regardless of the variety, the highest yields were obtained at a density of 7 plants per 1 m2.
