Two field trials were conducted at the Experimental Farm, Faculty of Agriculture, Al-Azhar University at Assiut Governorate, Egypt, during the summer of 2014 and 2015 seasons to study the effect of four patterns intercropping and three time cutting. Soybean as main crop with guar as secondary crop beside solid planting of each crop on yield and its components, as well as chemical contents of both crops in addition to competitive relations and the economic return . Pattern of (P9) significantly increased plant height of soybean as compared with pure stand and other intercropping patterns. The intercropping pattern of (P2) soybean produced the greatest values of No. of bonds/plant, 100-seed weight, seed yield/plant and seed yield/fed. while seed yield/fed. hat the minimum reduction at (P9) pattern. The pure stands of the guar plants produced the maximum forage yield/fed Ton. as compared with other intercropping patterns in both seasons. Meanwhile, growing guar under the intercropping pattern of (P9) produced the highest values of forage yield/fed. as compared with the other intercropping patterns in both seasons. The protein ratio/plant grown soybean under intercropping pattern of (P11) produced the maximum as compared with all the other intercropping patterns Meanwhile, growing soybean under the intercropping pattern of (P2) produced the highest value oil ratio seeds/plant. The intercropping patterns of (P9) of guar produced the greatest values of the protein ratio/plant and total ash/plant as compared with other intercropping patterns in both seasons. The highest value of crude fibers for the guar crop was (P10) intercropping pattern. Intercropping pattern (P11) was the best for land utilization from land equivalent ratio (LER) and relative crowding coefficient (RCC). Soybean (dominant) and guar had the lowest values for aggressivity.
