The purpose of this study was to determine the extent of the impact of the combination predecessor – nitrogen fertilizer rate on: The amount of grain yield; Growth and development of crops; Individual parameters and components of crop yield; The quality of grain and biomass yields; Reutilization effectiveness of carbon and nitrogen in the biomass; The use and reutilization of phosphorus, and Efficiency of nitrogen fertilizer for new and current Bulgarian winter wheat varieties. It was found that the introduction of leguminous crop rotation predecessor in most positively affected overall performance and productive crop density, total and productive tillering and plant height. Nitrogen fertilizer rate defines the average number and weight of grain in the class whose values do not differ after various ancestors, but of different fertilizer levels, their differences are statistically proven. The absolute mass of grain and harvest index depend on the genotype and did not change significantly in the increase in fertilization. Grain yield was positively correlated with crop density, total and productive tillering, plant height, number and weight of grain in class.
