This experiment was conducted to study the effects of genotypic differences in dry weight accumulation, N assimilation and redistribution, and N redistribution efficiency of different plant parts on seed yield and protein content among three faba bean cultivars, using a randomized complete block design. The total dry weight accumulation in different growth stages showed significant differences among cultivars during vegetative growth and early flowering, and during flowering and early seed filling. N was assimilated throughout the growth but a large quantity was assimilated during seed filling ranging from 47.66 to 56.50 of the total plant N. The redistribution of n from leaves, stems and pod walls to the seeds ranged from 26.66 - 31.42, 6.89 - 11.05 and 12.24 - 20.51 of the seed N content, respectively. The remaining seed N content was assimilated during seed filling which accounted for 40.04 - 52.15. High protein content in seeds seemed to be due to the greater N assimilation during seed filling rather than to the N redistribution efficiency from the vegetative plant parts.
