The effects of fungicidal seed dressing and Rhizobium inoculation on the chemical properties of faba bean seeds were studied. Two fungicides, Captan and Fernasan-D at concentrations between zero and 10 g/kg seeds were used. Inoculation with Rhizobium leguminosorum bv. viceae strain TAL 1397 immediately before or after seed dressing or inoculation at the seedling stage was adopted.Compaired to uninoculated plants, Rhizobium inoculation by both methods significantly (P≤0.01) increased  seed moisture content, fat content, fibre and protein content. Carbohydrate content was significantly (P≤0.01) decreased while  no effect was detected on ash content. No clear differences were observed between inoculation immediately before or after seed dressing (First season). Fungicide seed dressing significantly (P≤0.01) increased ash, moisture and carbohydrate contents when applied at the field recommended dose. Fat, fibre and protein contents were significantly (P≤0.01) decreased with different degrees depending on fungicide toxicity and concentration. Increasing the concentration of both fungicides resulted in lower contents of fat, fibre and protein contents. No differences between the two fungicides were observed in the contents of moisture, ash and crude fibre. Captan seed dressing resulted in lower fat and crude protein content and higher carbohydrates content compared to Fernasan-D.
