The aim of the study was determination of the influence of differentiated plant density and nitrogen fertilization on the growth and yielding of blueweed. In experiment the seeds of blueweed cv. Bedder were sown at the end of April in rows 45 cm apart - 4.0 kg per ha. After developing sprouts, thinning were done to estabilish respective plants population (10, 20, 30 and 40 plants per square m). The effect of plants population was examined at two levels of nitrogen fertilization (0 and 50 kg N per ha). The plants that grew at the smallest population were highest, had greatest number of side branches and produced greatest mass per plant. The yield of seeds calculated per ha in this object was the smallest and seeds contained less fat as compared with another plant densities
