摘要：

A field investigation of two faba bean cultivars (cv.), Agabat and Silaim, showed that bean yellow mosaic virus (BYMV) infection reduced (p less than or equal to 0.001) yield (Kg/ha), protein content and in vitro protein digestibility (IVPD) but increased (p less than or equal to 0.05) tannin content (mg/100 ml). Nitrogen fertilization with viral infection significantly reduced yield and IVPD for cv. Silaim and increased (p less than or equal to 0.05) protein and tannin contents. Nitrogen fertilization alone was found to increase (p less than or equal to 0.05) yield, protein and tannin contents but slightly reduced IVPD. Rhizobium inoculation with viral infection significantly decreased yield per unit area, protein content and IVPD, but increased (p less than or equal to 0.05) tannin content. Rhizobium inoculation alone significantly increased (p less than or equal to 0.001) yield and tannin content and slightly increased protein content but decreased IVPD. The results indicated that nitrogen fertilization or nitrogen fixation increased yield, protein and tannin contents and decreased IVPD. Viral infection had an adverse effect on yield, protein content and IVPD but had no effect on tannin content.
