In order to assess soybean, sweet basil and borage yield intercropping system, an experiment wasconducted based on randomized complete blocks design with 9 treatments and three replicates in 2011.Treatments were consisted of replacement ratios of 75: 25, 50: 50, 25: 75 soybean: sweet basil and borageand pure culture of each plant. The results showed that the first pod in 75: 25 soybean: borage and solecropping of soybean observed to be positioned at upper height than other treatments. The node number ofstem was more in intercropping treatments than sole crop. In intercropping treatments, the pod numberper plant except 25: 75 soybean: borage and seed number per plant except 25: 75 and 50: 50 soybean:borage was higher than sole crop. Seed yield and biological yield was decreased by increasing sweet basiland borage proportions in intercrop except 75: 25 soybean: sweet basil. The seed yield and dry weight ofplant of intercropping was higher than pure culture of soybean. Yield of sweet basil in both growth periodand also seed yield of borage was decreased through increasing soybean presence. Area-time equivalentratio indicated 9, 11 and 14 percent advantages of the 75: 25 soybean and sweet basil and borage ratio and50: 50 soybean and borage compared to monoculture, respectively.
