Abstract: This study was aimed to determine the effect of different intercropping systems on growth, yield and quality of green bean under field conditions. Land Equivalent Ratio (LER) was determined as an index of intercropping advantage and economic net income to assess the efficiency of different cropping systems. Green bean (Phaseolus vulgaris L. cv. Paulista) as a main crop was intercropped with head lettuce (Lactuca sativa L. cv. Target) and/or green onion (Allium cepa L. cv. Giza 20) as intercrop. Lettuce was planted on the other side of green bean rows in the same time green onion was planted on both sides of the row. All crops were also grown in pure stands. Results indicated that all intercropping systems used in this trail had positive effects on land use efficiency and available growth resources. All intercropping systems used did not affect the yield of green bean. Nitrogen, phosphorus and potassium contents of bean leaves did not vary significantly in response to cropping systems. Under investigation conditions, LER and net income increased when all intercropping systems were used.
