| Abstract | ||||
| Two field trials were carried out at the Agricultural Experimental Station, Faculty of Agriculture, Cairo University during 2000/2001 and 2001/2002 seasons to study the effect of intercropping faba bean at different plant densities with sugar beet on growth, yield and yield components of both crops. Sugar beet seeds were sown in hills spaced 20 cm apart on one side of the ridge whereas faba bean was seeded on the other side of the ridge in hills spaced 10, 20, 30 or 40 cm apart at one or two plants/hill. The results obtained indicated that growth yield and yield components of sugar beet were significantly decreased by faba bean intercropping compared with solid sugar beet in both seasons. Chemical traits of sugar beet and root/ratio were insignificantly affected by intercropping patterns in both seasons. Sugar beet yield and its attributes were significantly reduced with increasing plant density of the over story crop. The intercropping pattern including 100% sugar beet plus 12.5% faba bean recorded the highest sugar beet root yield, which were 95% and 93% of its pure stand in the first and second seasons, respectively. However, intercropping sugar beet with 100% faba bean density recorded the lowest values of sugar beet root yield and its attributes in both seasons. Estimated sugar yield showed the same trend. NI faba bean traits except 100 seed weight were significantly affected by intercropping in both seasons. The highest faba bean yield was obtained from 100% sugar beet and 100% faba bean pattern, which were 70 and 74 % of the pure stand in both seasons, respectively. The lowest values were obtained from 100% sugar beet and 12.5% faba bean pattern (25% fate bean) in both seasons. The maximum values of Land Equivalent Ratio (LER), 1.36 and 1.38 in the first and second seasons were recorded when 100% sugar beet and 33% faba bean was applied. Intercropping 33 % of faba bean with 100% sugar beet recorded the highest values of Relative Crowding Coefficient (K) in the first and second seasons. Faba bean was the dominant partner in all-intercropping patterns, in both seasons. The highest values of total income were recorded from intercropping 100% sugar beet with 33 % faba bean in both seasons. | ||||
