The research was carried out during 2017/2018 growing season at Buqa Farm, Faculty of Agricultural Engineering, Tishreen University in Lattakia, to study the effect of plant density and infection with mosaic cucumber virus on the productivity of beans (Vicia faba L.). The local bean variety was used with three plant densities (5, 10 and 20 plants/m2). Virus infection was made when the length of the plant reached 15 cm. The design of the experiment was carried out according to the Randomized Complete Block Design (RCBD) with the arrange of split plot with three replicates. The treatments of infection were distributed to the main plots while the sub plots included the density treatments. Results showed that the plant density of (5 plants/m 2) surpassed the plant densities of (10, 20 plants/m2) in number of branches per plant and fresh green weight of the plant at pods formation stage and the number of pods per plant. The plant density of (20 Plants/m 2) surpassed the other densities (5 and10 plants/m2) in seed yield and weight of 100 seeds, and the height of the plant. The infected plants (E0) when planted at high density (20 plant/m2) had the highest seed yield and weight of 100 seeds. The infection with mosaic virus did not affect the height of the plant, and the healthy plants (E1) were superior to infected plants (E0) in all studied traits (The plant height had declined by 10.23- 12.17% and fresh green weigh for each plant by 0.76- 1.77% and the number of pods per plant had declined by 14.08- 31.76 % and the seed yield by 13.80 – 19.84 % and weight of 100 seeds by 1.77-5.50 % in the infected plants by mosaic cucumber virus compared to the healthy plants )
