Winter barley (Hordeum vulgare L.) is an important crop in Romania grown under different pedoclimatic conditions over whole country. The aim of this study was to establish the influence of four different sowing densities (300, 400, 500 and 600 seeds/m2) of Lucian variety and of Jallon hybrid (200, 250, 300 and 350 seeds/m2), under pedoclimatic conditions of Giurgiu county during 2021-2022. Assessments were conducted in order to evaluate production elements and the quality indexes (number of tillers, plants height, number of ears, number of grains/ears, the 1,000-grains weight, protein content and starch content). The results obtained showed that yield was obviously influnced by sowing density and by variety grown. Hybrid Jallon has provided the highest yield (7,875 kg/ha) when sown at 350 seeds on square meter. An yield of 6,487 kg/ha has been recorded when Lucian variety was sown at 600 seeds on square meter. Productivity elements and quality indicators of barley yield were strongly influenced more by sowing density than variety sown.
