<br/><br/> Two field experiments were carried out at the Experimental farm of Hort. Res. Inst. (Qaha farm), Kalubia Governorate,  Egypt during 2009/10 and 2010/11 seasons to determine the effect of intercropping of green onion (Allium cepa L. cv. Giza 20)  with lettuce (Lactuca sativa L. cv. Dark Green) and/or spinach (Spinacia oleracea L. cv. Saloniki) on growth,  yield and quality of the sole and intercropped plants. Land Equivalent Ratio (LER) was evaluated as a real index  for intercropping advantages and economic net income to assess the efficiency of different culture systems applied in this study.
