Field trial was conducted at El-Serw Research Station, A.R.C., Damietta Governorate, during 2017/2018 and 2018/2019 seasons to study the intercropping faba bean plant densities (33.3, 25.0 and 16.7%) with three sugar beet variety or genotype namely; Glorius (Z), Lilly (N) and Cleopatra (E). Split plot design with three replications was used. Results showed that the interaction between sugar beet varieties and faba bean plant densities significantly affected leaf area index (LAI), root diameter, root and sugar yields fed-1 and sucrose % in both seasons and other traits significantly affected in one season. Intercropping faba bean with Glorius variety had the highest yield and its attributes of faba bean comparison to those intercropping with other varieties in both seasons. Yield attributes of faba bean significantly increased by decreasing faba bean plant density from 33.33 to 16.7%, while the converse was hold true for plant height and seed yield fed-1 in both seasons. All studied traits of faba bean were not affected significantly by the interaction between sugar beet varieties and plant densities of faba bean in both seasons, except plant height in second season. The total land equivalent ratio (LER) and relative crowding coefficient (RCC) values were greater than one in all the studied treatments providing advantages of intercropping faba bean with sugar beet has advantages. Faba bean was dominant crop. Intercropping faba bean plants at 25% plant density with Glorius variety had the highest LER (1.29 and 1.33) and MAI (3449 and 4267) in both seasons.
