N2  - Two field experiments were conducted at Mal/awi Agricultural Research Station in Minia governorate (Middle Egypt) in 2004 / 2005 and 2005 / 2006 grown seasons, to study the effect of three preceding crops (maize, maize sequence berseem and soybean) and intercropping two legumes crops (fahl berseem and faba bean) on yield and yield components of wheat. The experimental design was split plots with three replications. The data obtained showed that grain and straw yield of wheat grown after maize sequence berseem or soybean were higher than grown after maize. Intercropping wheat with faba bean or fahl berseem resulted in increased yield components of wheat. Grain yield of wheat grown with faba bean was higher than that grown with fahl berseem.. Wheat was a superior intercrop component where the relative yield produced was equal to that obtained from 90 to 94 % of solid. While the relative yield obtained of fahl berseem and faba bean was 16-19% for fahl berseem and 35 to 39 % for faba bean. The values of competitive ratio (CR) for wheat were greater than for common faba bean or fahl berseem indicating the dominance of wheat under these crops mixtures. Similar trend to that of land equivalent ratio (LER) and competitive ratio (CR) was also observed for actual yield loss (AYL). The values of AYL for faba bean was positive in faba bean and Wheat, which indicated a yield advantage for faba bean- wheat, While, A YL values for fahl berseem was negative in common fahl berseem wheat, which indicated a yield disadvantage for fahl berseem. AYL values for wheat was positive in the common fahl berseem wheat and faba bean, wheat. The highest gross return (7156.85 L.E) was obtained by intercropping wheat with faba bean grown after maize followed by intereropping wheat with faba bean grown after soybean
