Abstract
Nitrogen management in winter wheat is one of the most studied agricultural practices. Optimization of nitrogen nutrition and sowing density requirements of specific winter wheat cultivar are major objectives for improvement of trade-offs between grain yield, environmental sustainability and maximum profitable production. Therefore, the aim of this study was to assess the effects of interaction between nitrogen fertilization and sowing density on grain yield and yield determinants of modern wheat cultivars. The trial consisted of five winter wheat cultivars, four top-dressing nitrogen doses and four sowing densities was carried out under rain-fed conditions at the experimental field of the Institute of Field and Vegetable Crops, Novi Sad, Serbia. The analysis of variance showed statistically significant effects of all three factors on studied traits, while significance of interactions between studied treatments varied among traits.
