The objective of this research was to investigate different levels and the combined effect of nitrogen and phosphorus on the nodulation and yield components of faba bean (Vicia faba L.). A large seeded 584-066 accession numbered faba bean line, which was taken from a breeding program of the Field Crops Department, was used in the experiment. Four different nitrogen (0, 30, 60, 90 kg/ha) and three phosphorus (0, 40, 80 kg/ha) levels were applied to the soil at the sowing time. The number of pods/plant, biological and grain yield per unit area, together with grain and plant N content, were increased by 60 kg/ha nitrogen combined with 40 kg/ha phosphorus applications. The highest nodule and nodule weight/plant and 100-kernel weight were obtained from 80 kg/ha phosphorus and 30 kg/ha nitrogen combination.
